Managed browser DLP & extension governance
Secure Google Chrome, Microsoft Edge, Mozilla Firefox 128+, and Apple Safari 26+ without forcing employees onto a dedicated enterprise browser or installing a kernel agent. Mask or block sensitive AI inputs, block unauthorized domains, score Chrome and Edge extension permission exposure, and spot bulk file downloads.

What Browser DLP covers
Standalone enterprise browsers create adoption friction, while OS endpoint DLP agents slow down developer machines. Elba ships as a lightweight Manifest V3 extension deployed through your MDM.
Inspect drafts and text or code attachments (up to 5 files / 16,000 characters) on ChatGPT, Claude, Gemini, and Copilot. Replace sensitive entities with realistic fictional values (18s fail-closed) or block submission outright.
Inventory installed browser extensions across Chrome, Edge, and Firefox 128+, and evaluate extension permission exposure (Low, Medium, High) on Chrome and Edge without maintaining brittle 32-character ID spreadsheets by hand.
Block unapproved web domains, detect bulk downloads of 10 or more files on Chrome, Edge, and Firefox 128+, and enroll Chrome and Edge silently with Google, Microsoft 365, or Okta identity plus Windows TPM device signals.
Browser runtime & architecture matrix
Keep employees in their native browsers while pairing last-mile controls with cloud SaaS DLP and access reviews.
| Browser security dimension | Dedicated enterprise browser | OS endpoint DLP / TLS proxy | Elba managed browser extension |
|---|---|---|---|
| Employee browser experience | Forces staff off Chrome, Edge, Firefox, or Safari onto a new browser | Installs kernel agents or TLS certificates that break dev CLIs | Runs natively inside Chrome, Edge, Firefox 128+, and Safari 26+ (macOS 26+) |
| AI prompt & code upload protection | Policy rules locked inside the replacement browser only | Heavy regex tuning with frequent false-positive blocks | Fictional-value prompt masking (18s fail-closed), blocking, and 5-file / 16k-char text/code DLP |
| Chrome & Edge extension risk | Restricts store access but blind to existing Chrome/Edge fleets | Network proxies cannot see local browser extension permissions | Extension inventory (Chrome, Edge, Firefox) + Low/Medium/High permission scoring (Chrome, Edge) |
| Bulk downloads & unauthorized domains | Browser-locked policies with high per-seat add-on licensing | Generates raw SOC logs without owner follow-up | Domain blocking + bulk-download alerts (>=10 files on Chrome, Edge, Firefox) + Sam workflows |
| Cloud SaaS oversharing & OAuth gaps | Blind to historical Anyone links in Google Drive or SharePoint | Requires separate SSPM and awareness contracts | Included in one platform with 7-source Cloud DLP, OAuth audits, and 46-app access reviews |
Deployment to enforcement
Use ready-made policies for Microsoft Intune, Windows GPO, Google Admin Console, macOS MDM, Apple DDM, or RMM PowerShell.
Force-install the Manifest V3 extension on Chrome, Edge, and Firefox 128+, and deploy the Safari 26+ package on macOS 26+ via Apple DDM or .pkg with enrollment heartbeat tracking.
Review discovered web apps, personal vs work AI sessions, High-exposure Chrome and Edge extensions, and bulk-download events from one unified inventory.
Turn on Automated Prompt Masking or Prompt Blocking, block unapproved domains, and let Sam send brief guidance in Slack, Teams, Google Chat, or email when risky behavior occurs.
Connected workflows & documentation
A closer look
Google Chrome and Microsoft Edge support the full suite: Shadow IT/AI visibility, AI account context, AI prompt masking/blocking and text/code upload DLP, unauthorized domain blocking, peer extension inventory, Low/Medium/High permission exposure scoring, bulk-download detection (>=10 files), silent identity sign-in, and Windows TPM signals. Firefox 128+ supports all of these except permission exposure scoring and silent sign-in. Safari 26+ (on macOS 26+ via .pkg or Apple DDM) supports app visibility, AI account status, AI prompt/text-upload DLP, browser logs, and enrollment heartbeat.
Browser upload DLP evaluates up to 5 text or source-code files (up to 16,000 characters per check) attached to ChatGPT, Claude, Gemini, or Copilot prompts. Binary files such as PDFs, Office documents, images, and archives record metadata in the browser while API-connected cloud drives scan full PDF and Office text.
Elba enforces an 18-second fail-closed timeout on automated prompt masking. If sensitivity replacement cannot finish within that window, the submission is blocked so unmasked sensitive data is not sent.
No. Elba focuses on business SaaS discovery, configured domain rules, and supported AI assistants without decrypting network traffic, and never stores raw prompt text or personal email addresses.
