Browser Guard

Proactively protect your browser
against new web threats. 

Security from threats. Seen and unseen.

Trend Micro™ Browser Guard is an easy-to-use browser plug-in that prevents both known and unknown web threats. Zero-day attacks, such as Aurora and Hydraq, are proactively blocked by Browser Guard, which detects and prevents behavior associated with these types of threats. Browser Guard also protects you from malicious JavaScript inserted into web pages where attacks can happen without any visible effect.

Browser Guard has zero-day vulnerability prevention and protects against malicious JavaScript using advanced heuristics and emulation technologies.

Browser Guard is quickly and continuously updated to deliver the most secure and up-to-date technology. The latest version includes detection enhancement for Web Trojans, and for tracing infection chains.
