Fortify Every Endpoint Against Data Breaches with Strac Endpoint Data Loss Prevention

What is Endpoint DLP Security?

Endpoint DLP (Data Loss Prevention) security protects sensitive data directly on employee devices like laptops and desktops. It monitors how files and data move across endpoints — including USB drives, browsers, desktop apps, cloud uploads, and AI tools — and prevents unauthorized exfiltration of sensitive information such as PII, PHI, source code, and customer data.

Modern Endpoint DLP goes beyond just blocking file copies. It includes real-time detection, historical scanning of existing files, visibility into which applications accessed a file, and enforcement across browsers and GenAI tools. Strac’s Endpoint DLP extends traditional endpoint protection by combining endpoint agents with browser and GenAI DLP, so sensitive data is protected even when users upload content to tools like ChatGPT or Gemini.

Why Endpoint DLP Protection is Broken in 2026 (Agent-only thinking is dead)

Traditional Endpoint DLP tools were built for a world where data lived mostly on laptops and moved via USB or email. That world is gone.

Today, most data exfiltration happens through:

• Browsers (uploads to personal Google Drive, Dropbox, Notion)
• SaaS apps (Slack, Jira, Zendesk, Salesforce)
• GenAI tools (ChatGPT, Claude, Gemini, Copilot)

Agent-only Endpoint DLP can’t reliably see or control these modern exfiltration paths. Even worse, many legacy tools still rely on brittle regex rules, creating massive false positives and alert fatigue.

Strac’s approach combines:

• Endpoint visibility
• Browser-based DLP
• GenAI DLP
• Data lineage across local files

This ensures Endpoint DLP protection works in the real world — where users copy-paste into AI tools, drag files into browsers, and sync data to cloud apps.

How Endpoint DLP Works (Real-time + historical scanning)

Modern Endpoint DLP works in two modes:

1) Real-time protection
Strac monitors file access, uploads, copy-paste events, and browser activity in real time. If sensitive data is detected during a risky action (e.g., uploading to ChatGPT or personal cloud storage), Strac can alert, redact, or block the action instantly.

2) Historical discovery & remediation
Strac also scans existing files on endpoints to discover sensitive data already sitting on laptops. This helps security teams answer:

• Where is sensitive data stored locally?
• Which files are high-risk?
• Who accessed them?

This dual approach ensures Endpoint DLP is not just reactive, but also proactive in reducing long-term data exposure.

Endpoint DLP for Windows

Strac provides deep Endpoint DLP protection for Windows devices, covering:

• File access and file movement tracking
• Browser-based uploads to personal cloud apps and AI tools
• Detection of sensitive data before exfiltration
• Visibility into which Windows applications accessed sensitive files

This allows security teams to prevent data leaks even when employees use unmanaged apps or personal accounts on corporate Windows laptops.

Endpoint DLP for macOS

Strac’s macOS Endpoint DLP protects sensitive data on MacBooks used by engineers, executives, and go-to-market teams. It provides:

• Real-time monitoring of sensitive file access
• Detection of uploads via browsers and desktop apps
• Visibility into risky user behavior
• Integration with browser-based and GenAI DLP policies

This ensures sensitive data stays protected even when users copy files into SaaS apps or AI tools from macOS devices.

Endpoint DLP for GenAI & Browsers (ChatGPT, Claude, Gemini)

The biggest blind spot in Endpoint DLP today is GenAI.

Employees increasingly paste sensitive data into:

• ChatGPT
• Claude
• Gemini
• Copilot
• Other AI copilots

Strac’s Endpoint DLP integrates directly with browser-based DLP to inspect prompts, file uploads, and responses flowing into GenAI tools. This allows organizations to:

• Detect sensitive data before it leaves the endpoint
• Block or redact sensitive content in AI prompts
• Alert users in real time
• Create audit trails for AI usage involving sensitive data

This bridges the gap between Endpoint DLP and GenAI governance — a critical requirement for modern enterprises rolling out AI at scale.

Data Lineage for Endpoint DLP (Strac’s Differentiator)

Most Endpoint DLP tools can tell you that a file was uploaded. Very few can tell you where that file came from.

Strac’s Data Lineage for Endpoint DLP tracks:

• Which local file was accessed
• Which application opened it
• Whether the file was copied, transformed, or uploaded
• Where the data ultimately went (browser, SaaS app, GenAI tool)

This lineage view helps security teams answer questions like:

“This sensitive snippet was pasted into ChatGPT — which original file did it come from?”

This context dramatically improves investigations, insider risk detection, and compliance reporting.

Endpoint DLP vs Network DLP vs SaaS DLP

Endpoint DLP, Network DLP, and SaaS DLP solve different parts of the data protection problem:

• Endpoint DLP protects data at the source — on employee devices
• Network DLP inspects traffic flowing through corporate networks
• SaaS DLP secures data stored and shared within SaaS applications

In a remote, cloud-first world, Endpoint DLP alone is not sufficient. Users work outside corporate networks and move data directly from endpoints into SaaS apps and AI tools. Strac combines Endpoint DLP with SaaS and Browser DLP to provide end-to-end data protection across the entire data flow lifecycle.

How Strac Endpoint DLP Works (Architecture)

Strac’s Endpoint DLP architecture combines:

• Lightweight endpoint agents for file visibility
• Browser-based DLP for cloud and AI uploads
• Centralized cloud policy engine
• Contextual ML-based classification
• Data lineage correlation across endpoints and SaaS

This unified architecture allows Strac to enforce consistent policies across Windows, macOS, browsers, and GenAI tools — without relying solely on brittle endpoint-only enforcement.

Endpoint DLP Use Cases

Common Endpoint DLP use cases include:

• Preventing engineers from uploading source code to ChatGPT
• Stopping customer data from being copied to personal Google Drive
• Detecting sensitive documents stored locally on laptops
• Monitoring risky data movement by departing employees
• Enforcing data protection policies on remote devices

Endpoint DLP is especially critical for companies in healthcare, fintech, SaaS, and AI-native organizations where sensitive data routinely touches employee endpoints.

Buyer’s Guide: What to Look for in Endpoint DLP Software

When evaluating Endpoint DLP solutions, look for:

• Real-time + historical scanning
• Coverage across Windows and macOS
• Browser and GenAI protection
• Data lineage and forensic visibility
• Low false positives using contextual ML
• Integration with SaaS DLP and DSPM
• Policy-based remediation (block, redact, alert)

If your Endpoint DLP vendor can’t see GenAI uploads or browser-based exfiltration, it’s already outdated.

Spicy FAQs: Strac vs Purview, Forcepoint

How is Strac different from Microsoft Purview Endpoint DLP?
Purview focuses heavily on Microsoft 365 workflows. It has limited visibility into non-Microsoft SaaS apps, browser-based uploads to personal accounts, and GenAI tools. Strac covers these gaps with broader endpoint + browser + GenAI coverage.

How is Strac different from Forcepoint or legacy Endpoint DLP tools?
Legacy Endpoint DLP tools were built for USB and email-era threats. Strac is built for modern data flows involving SaaS, browsers, and AI tools — with contextual ML and lineage rather than brittle regex-only enforcement.
