Browser Security Must Anchor Your Defense
Strategy
Lessons from the First Half of 2025
By Dakshitaa Babu, Security Researcher, SquareX
The security landscape of 2025 has crystallized around an undeniable truth: the web browser has
become both your most critical application and your greatest vulnerability. Looking at recent major
breaches, the pattern is clear - attackers have overwhelmingly shifted to browser-based attack vectors
that bypass traditional security controls entirely.
This shift isn't coincidental. As organizations moved critical operations to cloud applications, the browser
transformed from a simple website renderer into a complex application platform. It now functions as the
primary workspace where employees access sensitive data, corporate systems, and authentication
portals. Attackers have followed, developing sophisticated techniques that exploit the browser's
complexity.
