Browser Security

Working from home for many has become the “new normal” during the COVID-19 pandemic. Threat actors are shifting tactics to target these remote employees who may not benefit from corporate security. This makes the protection offered by web browsers more important than ever.

The ability to warn potential victims that they are about to stray onto a malicious website puts web browsers in a unique position to combat malware. Websites that trick (socially engineer) users to download malware have short lifespans, so it is essential that the site is discovered and added to the reputation system as quickly as possible. A good reputation system must be both accurate and fast to realize high catch rates.

Phishing attacks pose a significant risk to individuals and organizations by threatening to compromise or acquire sensitive personal and corporate information. Email, instant messages, SMS messages and links (URLs) on social networking sites are all vectors for phishing attacks. A browser’s ability to block malicious URLs was measured every six hours to determine how long it would take a vendor to add protection.

The Comparative Test Reports provide detailed results including block rates for each product and data recording consistency of protection over time.
