Insider risk stopped being a side conversation in security budgets once generative AI tools became part of daily work. An employee pasting a customer list into ChatGPT, a departing engineer zipping up a source-code repo the night before resignation, a contractor downloading a client database to a personal drive — these are the scenarios that insider risk management platforms are built to catch, and in 2026 three vendors dominate the conversation: Microsoft Purview Insider Risk Management, Proofpoint Insider Threat Management, and Incydr, the Code42 product now owned by Mimecast. This comparison breaks down pricing, detection architecture, and the real cost data behind why organizations are buying these tools at all.
The urgency is not hypothetical. According to the 2026 Global Cost of Insider Risks report from the Ponemon Institute and DTEX Systems, the average organization now spends $19.5 million a year managing insider incidents, up from $17.4 million in the 2025 edition of the same study. That increase landed the same year AI coding assistants and chatbots became standard office tools, and the report’s own framing, covered in a February 2026 GlobeNewswire release, is blunt: AI is creating new blind spots inside companies that thought they had insider risk under control.

What Insider Risk Management Actually Monitors in 2026
Insider risk management (IRM) platforms sit in an awkward middle ground between data loss prevention, user behavior analytics, and endpoint monitoring. Unlike a traditional DLP tool that blocks a file transfer based on a content rule, an IRM platform tries to build a behavioral picture of a person: what they normally access, what changed, and whether that change correlates with other risk signals like a resignation letter, a flagged HR event, or unusual after-hours activity. That behavioral layer is what separates Microsoft Purview Insider Risk Management, Proofpoint Insider Threat Management, and Incydr from a plain DLP policy engine.
All three vendors monitor overlapping but distinct data sources. Microsoft Purview leans on the Microsoft 365 graph — email, Teams messages, SharePoint, OneDrive, and, notably, Copilot prompts and responses, which makes it one of the few platforms that treats AI assistant usage as a first-class insider risk signal rather than an afterthought. Proofpoint Insider Threat Management pulls from endpoint activity, email, and cloud app telemetry into a single console with session timelines and screenshots. Incydr focuses tightly on data movement itself: file exfiltration across cloud storage, USB devices, browser uploads, and personal email, with less emphasis on broader behavioral scoring and more on catching the moment data actually leaves.
The practical difference shows up in deployment. Purview requires an existing Microsoft 365 E5 or Purview-specific licensing relationship and works best when an organization is already deep in the Microsoft ecosystem. Proofpoint ITM is platform-agnostic and commonly deployed alongside its email security stack, which overlaps with how organizations already evaluate Proofpoint against Mimecast and Microsoft Defender for email. Incydr, since the Mimecast acquisition, is increasingly sold as part of a bundled human-risk suite alongside Mimecast’s email security and the awareness training Mimecast has folded into its portfolio.
Insider Risk vs. DLP, PAM, and SSPM: Where the Category Lines Blur
One of the most common buying mistakes with insider risk management is assuming it replaces adjacent categories that security teams already own. It doesn’t, and understanding the boundaries helps explain why Purview, Proofpoint, and Incydr are priced and packaged the way they are.
Data loss prevention tools, like the ones compared in our look at Microsoft Purview against Forcepoint and Netskope for DLP, work by matching content against rules: block this file type, redact this pattern, quarantine this attachment. Insider risk management sits a layer above that, deciding which users and which moments deserve that scrutiny in the first place. Purview’s Adaptive Protection is the clearest expression of this relationship — it uses IRM’s behavioral score to decide how strict the DLP layer should be for a specific person at a specific time, rather than applying one static policy to everyone.
Privileged access management tools, the category covered in our CyberArk vs. BeyondTrust vs. Delinea comparison, control who can reach sensitive systems in the first place — vaulting credentials, enforcing just-in-time access, and session recording for admin accounts. Insider risk management assumes that access already exists and focuses on what a legitimately authorized person does with it. A PAM tool stops an unauthorized login; an IRM tool flags that an authorized engineer just downloaded ten times their normal volume of customer records the week before resigning. Organizations with mature security programs typically run both, because PAM and IRM catch different failure modes of the same underlying problem: trusted access getting misused.
SaaS security posture management, the category behind our AppOmni vs. Obsidian vs. CrowdStrike Falcon Shield comparison, is a third adjacent piece: it hardens the configuration of SaaS applications themselves, closing misconfigurations and excessive OAuth grants that insiders (or compromised insider accounts) could exploit. None of Purview, Proofpoint, or Incydr audit SaaS app configurations the way an SSPM tool does; they assume the SaaS environment is reasonably locked down and focus purely on user behavior within it. Buyers evaluating insider risk platforms in 2026 should budget for these categories as complements, not substitutes, which is also why Microsoft’s bundled Purview pricing — folding IRM, DLP, and eDiscovery into one contract — has a real cost advantage over stitching together point products from different vendors.
Microsoft Purview Insider Risk Management: Inside the Platform
Microsoft Purview Insider Risk Management is the deepest-integrated option of the three because it is not really a standalone product — it is a module inside the larger Purview data security suite, which also includes Data Loss Prevention, Information Protection, eDiscovery, Communication Compliance, and Audit. Microsoft’s pitch is correlation: instead of looking at a single risky action, Purview combines dozens of weak signals across the Microsoft 365 estate into a risk score per user.
Microsoft bills Insider Risk Management using Data Security Processing Units, or DSPUs, rather than a flat per-seat fee. One DSPU covers the compute needed to process roughly 10,000 user-activity log events, so the real cost depends heavily on how many indicators and users an organization enables in its policies — a company monitoring 500 high-risk users with a dozen indicators will consume far fewer DSPUs than one monitoring 50,000 employees with broad policies. Microsoft also sells IRM bundled into a broader Purview data-security package listed at $12 per user per month billed annually, and a lighter package for Microsoft 365 Business Premium customers at $10 per user per month billed annually that includes insider-risk analytics, Adaptive Protection, DLP, and data classification.
Adaptive Protection is Purview’s most distinctive feature heading into late 2026: it uses the insider-risk score to automatically tighten or loosen DLP enforcement in near real time, so a user who suddenly shows elevated risk signals gets stricter data controls applied without a human analyst manually adjusting policy. Microsoft also ships an Insider Risk Management solution built for Microsoft Sentinel, which correlates risk behavior signals across more than 25 Microsoft products, and the platform includes upward of 100 ready-to-use indicators and machine learning models out of the box, according to third-party product listings. The Copilot-monitoring angle is the feature security teams ask about most: Purview can search M365 data for Copilot prompts and responses tied to an investigation, giving it visibility other platforms currently lack into what employees are actually typing into Microsoft’s own AI assistant.
Proofpoint Insider Threat Management: The Telemetry-First Approach
Proofpoint Insider Threat Management takes a different architectural bet than Purview: instead of correlating signals across a single vendor’s productivity suite, it unifies endpoint activity, email metadata, and cloud telemetry into one console regardless of which cloud platform or office suite an organization runs. That cross-platform independence is Proofpoint’s main selling point against Purview, which only reaches full strength inside Microsoft 365.
Proofpoint ITM builds activity timelines complete with screenshots around flagged events, which gives investigators a visual record rather than just a log line. The platform ships with prebuilt alert libraries tuned for common insider scenarios — data exfiltration before resignation, mass file downloads, printing of sensitive documents — alongside privacy controls that let legal and HR teams limit what identifying information analysts see during an investigation, and geographic data controls for multinational organizations with regional privacy requirements like GDPR.
Pricing is where Proofpoint gets murky. An AWS Marketplace listing shows Proofpoint ITM priced around $1 per user, though the listing does not clearly specify whether that figure is monthly or an incomplete subscription fragment. Independent buyer guides instead cite an indicative range of $30 to $50 per user annually depending on deployment size and how many integrations an organization needs, which is roughly consistent with a quote-based enterprise sales motion rather than transparent self-serve pricing. Either way, buyers should treat any number here as a starting point for a sales conversation, not a locked list price — the same caveat that applies to Proofpoint’s email security and security awareness training products, which are also sold on negotiated enterprise contracts.
Incydr (Code42/Mimecast): Built for Data Exfiltration Detection
Code42 built Incydr around a narrower, sharper thesis than its two rivals: most insider risk tools drown analysts in behavioral noise, so Incydr tries to focus almost entirely on the moment data actually moves somewhere it shouldn’t. Mimecast, which acquired Code42 in July 2024 in a deal with undisclosed financial terms, has kept the Incydr name and architecture largely intact while folding it into a broader human-risk platform that also covers email security and security awareness.
Incydr tracks file movement across cloud storage services, USB drives, browser uploads, airdrop-style transfers, and personal email accounts, flagging exfiltration events without requiring an organization to write detailed DLP content-matching rules first. It is sold as a quote-based, per-user subscription with tiered packages rather than published list pricing, and current packaging includes one cloud-exfiltration detector per license, with add-ons available for extending historical data retention up to three years — useful for post-incident forensic work when an investigation starts long after the actual data left the building.
The tradeoff with Incydr’s narrower focus is that it does less of the broader behavioral correlation that Purview and Proofpoint attempt. Teams that want a single tool scoring overall employee risk across many signal types may find Incydr thinner on that front; teams that mainly care about catching data walking out the door — the single most common and costly insider scenario according to the Ponemon/DTEX data below — may find that focus to be exactly the point.

Pricing Breakdown: What Each Platform Actually Costs
None of these three vendors publish a clean, directly comparable per-seat price, which is itself a useful data point — insider risk management remains a negotiated-enterprise-contract category in 2026, not a self-serve SaaS purchase. That said, the available pricing signals diverge in instructive ways.
| Platform | Published or indicative pricing | Billing model | Notes |
|---|---|---|---|
| Microsoft Purview IRM (bundled, broader Purview package) | $12/user/month, billed annually | Per-user annual commitment | Includes DLP, Information Protection, eDiscovery, audit, communication compliance |
| Microsoft Purview IRM (Business Premium package) | $10/user/month, billed annually | Per-user annual commitment | Lighter bundle: insider-risk analytics, Adaptive Protection, DLP, data classification |
| Microsoft Purview IRM (standalone consumption) | Variable, billed in DSPUs | Consumption-based | 1 DSPU ≈ compute to process 10,000 user-activity logs; cost scales with indicators/users enabled |
| Proofpoint ITM (AWS Marketplace) | ~$1/user (term ambiguous) | Marketplace listing | Listing does not clearly specify monthly vs. annual |
| Proofpoint ITM (indicative enterprise) | $30–$50/user/year | Quote-based | Varies with deployment size and integration count |
| Incydr (Code42/Mimecast) | Quote-based, tiered | Per-user subscription | No public list price; add-ons for extended retention |
The takeaway for budget planning: Microsoft’s bundled packages give finance teams the clearest number to model against, largely because Microsoft is selling insider risk as a line item inside a much larger Purview compliance suite that organizations often already need for DLP and eDiscovery. Proofpoint and Incydr both default to sales-quoted pricing, which typically means better per-seat economics at scale but more friction for small security teams trying to get a fast budget estimate without engaging a sales cycle.
Benchmarks: Cost, Containment Speed, and User Ratings
Insider risk tools don’t have a clean FPS-style performance benchmark the way GPUs or LLMs do, so the most meaningful comparative data comes from three different angles: independent cost-of-incident research, vendor-marketplace listings, and user review platforms.
First, the Ponemon Institute and DTEX Systems’ 2026 Global Cost of Insider Risks report, the most frequently cited independent research in this category, found that containment speed is the single biggest cost driver. Organizations that contained an insider incident in under 30 days paid an average of $14.2 million annually in insider-risk-related costs, while those that took more than 90 days to contain an incident paid $21.9 million annually — a direct demonstration of why faster detection tooling pays for itself. The report does not break out the share of organizations containing incidents within 30 days. The 2026 report put average containment cost at $247,587 per incident, up from $211,021 in the 2025 edition, and average time to contain an incident actually improved to 67 days, down from 86 days in 2023 — evidence that better tooling, including platforms like the three compared here, is helping some organizations move faster even as overall incident costs rise. The report also broke out incident type: negligent insider incidents averaged $747,107 each, while malicious insider incidents averaged a close $742,125.
Second, on marketplace and review signals, Microsoft Purview Insider Risk Management holds a 4.3 out of 5 rating from a small base of 16 reviews, while Proofpoint Insider Threat Management holds the same 4.3 out of 5 score across a larger pool of 48 reviews, according to user review aggregation. For context, the broader insider threat management category on the same review platform averages 4.6 out of 5 across 176 reviews, suggesting both named products track slightly below the category’s overall satisfaction average — though with sample sizes this small, that gap is more directional than statistically decisive.
Third, AWS Marketplace listings function as an informal pricing benchmark across the category: Proofpoint’s ITM marketplace listing sits at the low single-digit-dollar range per user, reinforcing that cloud marketplace pricing for insider risk tooling tends to undercount what enterprises actually pay once implementation, integration, and support are added through a direct sales relationship.
Taken together, these three data points tell a consistent story: the headline list price is rarely the real price, independent researchers are more useful for understanding the cost of getting insider risk wrong than for ranking vendors against each other, and review-platform sample sizes in this category are still small enough that a handful of enterprise deployments can swing a product’s average rating meaningfully. That’s a different dynamic than, say, EDR or SIEM, where thousands of G2 reviews make vendor comparisons statistically sturdier. Buyers should weight hands-on proof-of-concept testing more heavily than published ratings when evaluating insider risk tools specifically, because the review base simply hasn’t caught up to how fast the category is growing.
The Shadow AI Problem: Insider Risk Meets Generative AI
The reason insider risk management has become a 2026 board-level topic rather than a niche security purchase is the collision between hybrid work and generative AI adoption. The Ponemon/DTEX report’s own framing — that AI is creating new blind spots — reflects a shift security teams have watched happen in real time: employees now have a frictionless way to move sensitive company data outside the corporate perimeter just by typing it into a chat window.
This is also where the three platforms diverge most sharply in actual capability rather than marketing language. Microsoft Purview is currently the only one of the three with native visibility into Copilot prompts and responses, because it owns both the AI assistant and the data security layer sitting underneath it — a structural advantage that’s difficult for competitors to replicate without a comparable AI product of their own. Proofpoint and Incydr can both detect that a user uploaded a file to a browser-based AI tool or pasted a large block of text into an external site, but neither currently inspects the actual prompt content the way Purview can for Microsoft’s own Copilot.
That gap matters because the actual damage happens at the text level, not just the file level. An employee doesn’t need to upload a document to leak a trade secret; they can summarize it from memory into a prompt. Purview’s Copilot-specific visibility closes part of that gap for Microsoft’s own AI stack, but it offers zero advantage once an employee opens ChatGPT, Gemini, or Claude in a browser tab outside Microsoft’s ecosystem — which is most of the real-world shadow AI usage security teams actually worry about.
Implementation Timelines: What the First 90 Days Actually Look Like
Vendors rarely publish honest implementation timelines, so it helps to separate what each platform requires before it starts producing useful alerts rather than noise.
Microsoft Purview Insider Risk Management’s first obstacle isn’t technical, it’s organizational: policies require sign-off from legal and HR before activation, since the platform surfaces personally identifiable behavioral data that most jurisdictions treat as sensitive employee information. Once policies are approved, technical setup is comparatively fast for organizations already on Microsoft 365 E5, since the data connectors to Exchange, SharePoint, OneDrive, and Teams are native rather than bolted on. The slower part is tuning: Microsoft recommends running default policies in a learning period before acting on alerts, and most deployments take four to eight weeks to reach a state where the risk scoring reflects the organization’s actual behavioral baseline rather than generic defaults.
Proofpoint ITM’s rollout centers on endpoint agent deployment, which is the most labor-intensive step for any insider risk platform. Organizations need the agent installed across whichever endpoints they want visibility into, which for most mid-market and enterprise customers means working through an existing endpoint management tool (Intune, Jamf, or similar) rather than a manual push. Once agents are deployed, Proofpoint’s prebuilt alert libraries mean the platform can start generating useful signal faster than a platform built entirely around custom policy authoring, though security teams still typically spend two to four weeks adjusting alert thresholds to cut down on false positives tied to legitimate bulk file operations like quarterly reporting or audit prep.
Incydr’s narrower scope makes it the fastest of the three to stand up in most cases, since it isn’t trying to build a comprehensive behavioral profile — it’s watching specific exfiltration pathways (cloud uploads, USB, personal email, browser transfers) that are well-defined and don’t require the same multi-week learning period. Organizations that have used Incydr report getting to a working detection baseline within one to two weeks of agent deployment, though that speed comes at the cost of the broader correlation Purview and Proofpoint offer once you need to understand why a user’s risk score changed, not just that a file moved.
Real-World Insider Risk Incidents These Platforms Are Built to Catch
Vendor pitch decks lean on hypothetical scenarios, but recent incidents show the pattern isn’t theoretical.
- Coinbase, May 2025: Overseas customer-support contractors allegedly accessed and exfiltrated customer account data; Coinbase disclosed the breach after receiving a $20 million extortion demand tied to the insider-sourced data, as detailed in PKWARE’s 2025 breach roundup. This is the exact class of third-party/contractor access risk that drives IRM purchases outside of full-time employee monitoring.
- Disgruntled-employee extortion case, guilty plea September 2024: A former contract employee pleaded guilty to stealing sensitive company data and threatening to publish financial records and employee personal information unless paid $2.5 million, according to the National Insider Threat Special Interest Group’s incident report. Timeline-based platforms like Proofpoint ITM and Incydr are specifically built to flag the data-access spike that typically precedes this kind of scheme.
- OpenAI, October 2026: OpenAI fired three researchers over alleged mishandling of sensitive internal information outside established procedures, according to BBC reporting. It’s a reminder that insider risk isn’t limited to IT or finance departments — frontier AI labs now sit squarely in the same threat model.
- The departing-engineer scenario: A software engineer gives two weeks’ notice, then downloads a proprietary codebase to a personal cloud drive the night before their last day. This is the single most common pattern that Incydr’s exfiltration-focused detection and Purview’s resignation-correlated risk indicators are purpose-built to catch, since both platforms weight HR-event proximity heavily in their scoring.
- The shadow-AI paste scenario: A product manager pastes an unreleased roadmap or a customer contract into a public AI chatbot to get a faster summary, with no malicious intent and no awareness that the text may be retained by the AI vendor. This negligent-insider pattern, not malicious theft, is what the Ponemon/DTEX data suggests now costs organizations nearly as much per incident as deliberate insider attacks.
Use-Case Recommendations: Which Platform Fits Which Organization
There isn’t a universal winner here — the right pick depends heavily on existing infrastructure and what kind of insider risk actually worries the organization most.
- Organizations already on Microsoft 365 E5: Microsoft Purview Insider Risk Management is the pragmatic default, since the Copilot monitoring, Sentinel integration, and bundled DLP/eDiscovery functionality are difficult to replicate cost-effectively with a bolt-on third-party tool.
- Multi-cloud or non-Microsoft-centric enterprises: Proofpoint ITM’s platform-agnostic telemetry collection makes more sense than forcing a Microsoft-first tool onto a Google Workspace or mixed-cloud environment.
- Organizations primarily worried about data exfiltration, not broad behavioral scoring: Incydr’s narrower, exfiltration-first design avoids the alert fatigue that comes with broader behavioral platforms, which matters for lean security teams without a dedicated insider-risk analyst.
- Regulated industries needing privacy-sensitive investigations (finance, healthcare): Proofpoint ITM’s built-in privacy redaction and geographic data controls are specifically designed for jurisdictions with strict employee-monitoring and data-residency rules.
- Organizations already running Mimecast for email security: Incydr’s bundling into Mimecast’s human-risk suite creates procurement and integration efficiencies that are hard to match by mixing vendors across email security and insider risk.
- Security teams specifically worried about generative AI data leakage: Purview is currently the only option with native Copilot prompt/response visibility, though all three platforms can detect bulk uploads or large text pastes to external AI tools at the network or browser layer.
Migration Guide: Switching Insider Risk Platforms
Moving between insider risk platforms is a slower, higher-stakes migration than swapping most SaaS tools, because historical behavioral baselines and open case investigations don’t transfer cleanly between vendors. Security and compliance teams planning a switch in 2026 should expect roughly four phases.
Phase 1: Parallel run and baseline rebuilding
Run the new platform in parallel with the existing one for at least 30 to 60 days before decommissioning anything. Behavioral risk scoring needs a baseline period to understand what “normal” activity looks like for each user; switching cold means the new platform starts blind, exactly when an organization can least afford a detection gap. This is especially important moving onto Incydr or Proofpoint ITM from Purview, since neither inherits Microsoft’s existing Adaptive Protection risk history.
Phase 2: Policy and indicator mapping
Map existing detection policies to the new platform’s indicator framework rather than trying to recreate them identically. Purview’s 100-plus indicators don’t translate one-to-one to Proofpoint’s alert library or Incydr’s exfiltration detectors, so this phase typically becomes a policy redesign exercise, not a simple export/import. Prioritize re-implementing the highest-severity indicators first (resignation-correlated access spikes, bulk downloads, personal cloud uploads) before migrating lower-priority behavioral signals.
Phase 3: Investigation and case history archival
Export and archive open and historical case data from the outgoing platform before access is cut off, particularly for any case tied to active litigation, HR action, or law enforcement involvement. Legal holds don’t pause just because a security team changed vendors, and losing access to historical investigation evidence mid-litigation is a far costlier mistake than any migration delay.
Phase 4: Integration cutover and SIEM reconnection
Reconnect the new platform to SIEM and SOAR pipelines last, after confirming detection accuracy during the parallel-run period, to avoid flooding the SOC with duplicate or unvalidated alerts from a platform still being tuned. Purview’s native Sentinel integration generally makes this step fastest for Microsoft-centric SOCs; Proofpoint and Incydr both require manual connector configuration for most third-party SIEMs.
Pros and Cons: Microsoft Purview Insider Risk Management
- Pros: Native Copilot prompt/response visibility; bundled pricing with DLP and eDiscovery reduces total tool sprawl; Adaptive Protection automatically tightens controls on rising-risk users; deep Sentinel integration across 25-plus Microsoft products.
- Cons: Full value only realized inside Microsoft 365; DSPU consumption billing is harder to forecast than flat per-seat pricing; limited native visibility outside the Microsoft ecosystem, including non-Microsoft AI chatbots.
Pros and Cons: Proofpoint Insider Threat Management
- Pros: Platform-agnostic deployment works regardless of cloud or productivity suite; strong privacy-redaction and geographic controls for regulated industries; visual activity timelines with screenshots speed up investigations.
- Cons: Pricing is opaque and quote-dependent; no native generative-AI prompt monitoring; requires a separate agent and integration layer that Microsoft-centric shops don’t need with Purview.
Pros and Cons: Incydr (Code42/Mimecast)
- Pros: Sharp focus on data exfiltration reduces alert noise; bundles efficiently with Mimecast email security and awareness training; extended historical retention add-on supports long-tail forensic investigations.
- Cons: Thinner broad-behavioral risk scoring compared to Purview and Proofpoint; no public pricing; post-acquisition product roadmap under Mimecast remains less mature than its two more established rivals.
The Verdict: Which Insider Risk Platform Wins in 2026
There’s no single champion here, and the data backs that up. Microsoft Purview Insider Risk Management is the strongest pick for the large and growing share of enterprises already paying for Microsoft 365 E5 or a Purview compliance bundle, because its $10–$12 per user bundled pricing effectively absorbs insider risk monitoring into tools organizations need anyway, and its Copilot-specific visibility currently has no direct equivalent in the market. Proofpoint Insider Threat Management is the better fit for organizations that need vendor-neutral coverage across a mixed cloud and device environment, or that operate under strict regional privacy rules that demand built-in investigation redaction. Incydr is the right call for teams whose primary fear is data walking out the door — departing employees, contractors, and exfiltration via personal cloud storage — who want a leaner, more targeted tool rather than a full behavioral-scoring platform, especially if they’re already inside the Mimecast ecosystem.
What the 2026 Ponemon/DTEX numbers make clear is that speed, not platform brand, is the deciding economic variable: the gap between containing an incident in 30 days versus 90-plus days is $7.7 million a year in average organizational cost. Whichever of these three platforms an organization chooses, the real return on investment comes from how fast it gets fully tuned, integrated with SIEM/SOAR, and trusted enough by analysts to act on its alerts quickly — not from which vendor’s name is on the contract.
Frequently Asked Questions
What is insider risk management software?
Insider risk management (IRM) software monitors employee and contractor behavior across email, cloud storage, endpoints, and productivity tools to detect data exfiltration, policy violations, and behavioral patterns associated with malicious or negligent insiders, correlating multiple weak signals into a risk score or investigation case.
Is Microsoft Purview Insider Risk Management included in Microsoft 365 E5?
Insider Risk Management is part of the Microsoft Purview compliance suite, which is included with Microsoft 365 E5 licensing or available as an add-on through Purview-specific bundles priced between $10 and $12 per user per month, billed annually, depending on the package.
What happened to Code42 Incydr after the Mimecast acquisition?
Mimecast acquired Code42 in July 2024 for undisclosed financial terms and has integrated Incydr into its broader human-risk security platform alongside Mimecast’s email security and awareness training products, while largely keeping the Incydr product name and detection architecture intact.
Can insider risk management platforms detect data pasted into ChatGPT or other AI chatbots?
Microsoft Purview can natively inspect Copilot prompts and responses as part of an investigation, but it has no equivalent visibility into non-Microsoft AI tools. Proofpoint ITM and Incydr can detect file uploads or large data transfers to browser-based AI tools at the network or endpoint layer, but none of the three platforms currently inspects raw prompt text typed into third-party AI chatbots like ChatGPT, Gemini, or Claude.
How much does insider risk cost organizations on average in 2026?
The Ponemon Institute and DTEX Systems’ 2026 Global Cost of Insider Risks report found organizations spend an average of $19.5 million annually managing insider incidents, with average containment cost per incident at $247,587 and average time to contain an incident at 67 days.
Which insider risk platform is easiest to deploy for a non-Microsoft organization?
Proofpoint Insider Threat Management and Incydr are both built to be platform-agnostic and deploy via lightweight endpoint agents and cloud telemetry connectors, making them a more natural fit than Microsoft Purview for organizations running Google Workspace or a mixed cloud stack, since Purview’s deepest features depend on Microsoft 365 integration.
Do these platforms replace a DLP tool?
Not entirely. Microsoft Purview IRM is designed to work alongside Purview DLP and can dynamically adjust DLP enforcement through Adaptive Protection, while Proofpoint ITM and Incydr are commonly deployed alongside separate DLP tools rather than as full replacements, since DLP focuses on content-based blocking while IRM focuses on behavioral detection and investigation.
What is the biggest difference between malicious and negligent insider costs?
According to the 2026 Ponemon/DTEX report, the per-incident costs are surprisingly close: negligent insider incidents averaged $747,107 while malicious insider incidents averaged $742,125, suggesting that accidental data exposure from careless or untrained employees is now roughly as expensive as deliberate insider attacks.
