DefensX — Browser-Based Zero Trust Security

DefensX protects users at the browser level with zero-trust web isolation, content disarming, and real-time threat prevention. No VPN, no proxy, no endpoint agent required — security that works wherever your employees browse.

The browser is the new endpoint. Employees spend most of their day in a web browser — accessing SaaS apps, downloading files, clicking links in emails. DefensX secures this attack surface by isolating web content, disarming malicious files, and enforcing zero-trust policies at the browser level without requiring an endpoint agent or VPN.

Brivy IT deploys DefensX for clients who need an additional layer of protection against web-based threats — drive-by downloads, malicious redirects, credential harvesting, and phishing pages. It complements endpoint protection tools like ThreatDown by stopping threats before they ever reach the endpoint.

Core Capabilities

  • Browser Isolation — Render web content in an isolated environment so malicious code never executes on the user’s device, even on compromised or unknown websites.
  • Content Disarm & Reconstruction (CDR) — Strip active content from downloaded files (macros, scripts, embedded objects) and reconstruct clean, safe versions automatically.
  • Zero-Trust Web Access — Enforce access policies based on user identity, device posture, and content risk — not network location.
  • Phishing Protection — Real-time detection and blocking of credential harvesting pages, even zero-day phishing sites that haven’t been catalogued yet.
  • URL Filtering & Web Policies — Category-based web filtering with granular policies by user, group, or department.
  • Agentless Deployment — Deploy via browser extension or DNS — no heavyweight endpoint agent required. Works on managed and unmanaged devices.

Frequently Asked Questions

Does DefensX replace endpoint protection?
No. DefensX adds a security layer at the browser, complementing endpoint protection. Think of it as catching web-based threats before they reach the endpoint — while EDR tools like ThreatDown catch anything that gets through.
How does browser isolation work?
DefensX renders web content in an isolated environment (either cloud-based or local). The user sees a normal browsing experience, but malicious code, scripts, and exploits execute in the isolated container — never touching the actual device.
Does it work on personal devices?
Yes. Since DefensX can deploy as a browser extension without a full agent, it can protect employees browsing on personal devices — ideal for BYOD environments.
