Traditional detection-based security tools, including AV, EDR/EPP, firewalls, IDP/IPS, and SWGs/CASBs fail to address new zero-day threats because their reactive approach relies on signatures and IoCs, limiting their effectiveness to only attacks that have been seen before. Even AI tools integrated into these traditional systems are typically trained on existing attacks and Indicators of Compromise (IoCs), fundamentally limiting their ability to stop zero-day threats and giving enterprises a false sense of security. While many enterprises have attempted to improve browser security, they continue to focus on improving security at the network or endpoint level, failing to prevent sophisticated malware or advanced phishing threats for a number of reasons including:
While many enterprises have tried to improve browser security, they tend to focus on security at the network or endpoint level. These tools are not equipped to combat evasive threats in the browser and often don’t even see them until it’s too late.
