Web browsers have long been the security sinkhole of enterprise infrastructure. While email is often cited as the most common entry point, malware often enters via the browser and is more difficult to prevent. Phishing, drive-by attacks, ransomware, SQL injections, man-in-the-middle (MitM), and other exploits all take advantage of the browser’s creaky user interface and huge attack surface, and the gullibility of most end users.
It is this last item — humans — that is the problem, and we need to be protected against ourselves. This is especially true as SaaS applications grow in usage, not to mention that every piece of hardware seems to come with a web server (and therefore a browser) to configure it. These use cases are aided and abetted by the increasing number of work-from-home staffers who depend on more browser-based apps.
This is why enterprise secure browsers have finally gotten their moment. The category, which has been mostly flying under the radar for the past six years, has seen a lot of changes. Google announced its own entry into the field in 2025. Appaegis, Talon and Perception Point were acquired by Mammoth Cyber, Palo Alto Networks and Fortinet respectively, showing how this technology has become part of a larger security context. To that end, other established security vendors have brought forth products in what Gartner is now calling the “remote browser isolation” market to complement their zero trust, secure services edge, or posture management security platforms.
