Features

Enterprise browser extension management,
built for security teams

A lightweight agent gives you complete endpoint browser extension visibility across your fleet. Audit browser extensions across employees, enforce policy, and eliminate shadow IT browser extensions.

Real-time discovery
Complete browser extension inventory across Chrome, Edge, Firefox, Brave, and Safari. The agent polls every 90 seconds, automatically detecting new extensions installed across all managed endpoints.
Automated risk scoring
Browser extension risk scoring assigns every extension a score of 0–100 based on malicious extension threat intelligence, permission patterns, and metadata — surfacing malicious browser extensions before they become a problem.
Blocklist & allowlist
Browser extension policy enforcement across your entire fleet. Block specific extensions, or switch to allowlist mode for chrome extension allowlist management — deny everything except approved extensions, enforced via native browser policy.
Automated enforcement
When a blocked extension is detected, users receive a warning notification before automatic removal. Browser extension compliance monitoring keeps your fleet clean without manual intervention.
Multi-tenant dashboard
Each organization gets their own isolated subdomain dashboard. Role-based access for admins and analysts. Full audit trail and removal logs.
Slack & SIEM integration
Receive instant Slack alerts on browser extension security events. Forward all events to Splunk, Elastic, or any SIEM endpoint — full browser extension compliance monitoring in your existing security stack.

Built for enterprise security teams

Whether you're a 50-person startup or a 50,000-seat enterprise, Extensight gives you the browser extension inventory software and enforcement tools your security team needs.

Shadow IT
Eliminate shadow IT browser extensions
Employees install browser extensions that exfiltrate data, bypass DLP, or introduce malware. Extensight surfaces every extension instantly — block browser extensions by company policy or flag shadow IT browser extensions before they become a liability.
Compliance
Audit browser extensions across employees
SOC 2, ISO 27001, and HIPAA audits increasingly ask about endpoint software controls. Extensight is a browser extension security tool that lets you audit browser extensions across employees and generate evidence of your extension governance program.
Threat Prevention
Block malicious browser extensions enterprise-wide
Browser extension data exfiltration risk is real — compromised extensions have been used to steal credentials, session tokens, and sensitive data. Extensight's threat intelligence feed flags known-malicious extensions across your entire fleet automatically.
Policy
Block browser extensions by company policy
Use allowlist mode to enforce a strict approved-only policy, or blocklist mode to block specific high-risk extensions. Policies are enforced via native browser policy — no MDM required, though MDM browser extension control integrations are on the roadmap.
Visibility
SaaS browser extension monitoring at any scale

Manage browser extensions across your organization from a single dashboard — chrome extension management for enterprise teams made simple, with per-org isolation for MSSPs and multi-tenant deployments.
