Use Case

    Data Loss
    Prevention

    Control file uploads and downloads, mask sensitive data in web apps, and watermark web pages to prevent leakage through the browser. No proxies, just browser-native DLP that deploys in minutes.

    The Challenge

    Data Leaves Through the Browser

    A large portion of sensitive data exfiltration happens through web browsers, including uploads to personal cloud storage, file transfers to unauthorized apps, and downloads from compromised sites. Traditional DLP solutions focus on endpoints and networks, completely missing the browser channel where modern work actually happens.

    How Atakama solves this

    Inspect Classify Enforce

    Browser-native DLP covers uploads, downloads, and on-screen exposure, the moments where data actually leaves your environment.

    01

    Inspect

    Observe uploads, downloads, and on-screen rendering in real time. No proxy, no certificate, no inspection delays.

    02

    Classify

    Apply policy by destination URL, content category, and business vs. personal classification, per tenant.

    03

    Enforce

    Block, mask, warn, or allow with audit log based on the policy that fired. Users see clear interstitials when blocked.

    Capabilities

    Browser-Native Data Protection

    Control data movement at the point of action: uploads, downloads, on-screen rendering, and more.

    Report Uploads and Downloads

    Capture every upload and download across AI tools, SaaS, and file-sharing sites, with full user, destination, and file context for review.

    Classify by URL, Category, and Business Class

    Apply policy based on destination URL, content category, and business vs. personal classification so the right files move only to the right places.

    Mask Sensitive Data Inside Web Apps

    Hide PII fields in the rendered page so only authorized users see the full data, without modifying the underlying SaaS application.

    Block Uploads and Downloads by Policy

    Block file uploads and downloads by file type, destination URL, or content category, across SaaS, AI tools, and any other web app.

    Block Non-Business Destinations

    Block uploads to non-business websites and personal cloud storage so corporate data doesn't move into unsanctioned tenants.

    Apply DLP Across Every Web App

    Same upload, download, and masking policy applies to every web app users touch, no per-app integration or proxy required.
