In 2025, the browser has become one of the primary battlefields for cybercriminals. Once considered a simple access point to the internet, it now serves as the main gateway for employees into critical business applications and sensitive data. This shift has drawn attackers to target browsers directly, exploiting them as the weakest link in a highly connected and decentralized work environment. With enterprises relying heavily on SaaS platforms, online collaboration tools, and cloud applications, the browser has transformed into the focal point of modern cyberattacks, and security teams must rethink their defenses to stay ahead. 

The reason attackers focus on browsers is not because of the technology itself, but because of what lies beyond them. When a user logs into a SaaS tool, an ERP system, or a customer database, the browser acts as the entryway.
