How secure is your browser? That is a hard question to answer, but the folks from Skybox Security may have an answer. They took these variables into account: fewest exposed vulnerabilities, most published (and patched) vulnerabilities, and the shortest time between security patches.





Does this mean Opera is the most secure? Probably not as Opera's market share is around one percent so there's probably not a lot of interest in finding Opera vulnerabilities.

The next variable is the browser with the most published and fixed vulnerabilities. Chrome and Internet Explorer come head-to-head for this one, but bear in mind that vulnerabilities are still popping up in Internet Explorer 6 over 14 years after its release.

And finally, time between patches. Chrome is the most responsive to security vulnerabilities.



So, while there is no clear winner, bear in mind that each browser can reduce their attack surface if they can block high-risk vulnerabilities and make sure security controls and policies are effective.
