Chrome is the most secure browser of the top three

Internet Explorer second and Firefox a distant third.

In a recent study by the security research firm Accuvant Labs, the top three internet browsers in the world were thoroughly tested for security. Google’s Chrome came in first, Microsoft’s Internet Explorer came in second and Mozilla’s Firefox came in third; all three combined accounting for 93% of the global internet browser market share.

Instead of looking at historical data to see vulnerability of each browser, Accuvant instead had a more proactive approach, by looking at the anti-explotation safeguards implemented by each browser. Sandboxing, 3rd party plug-in security and JIT hardening are three key features that Chrome has successfully implemented, with Internet Explorer showing some deficiencies in. However, Firefox doesn’t have any of these technologies at all, making it one of the most vulnerable browser of the three.

Google Chrome 12 & 13, Internet Explorer 9 and Firefox 5 were tested for this study running on Windows 7 (32bit).  As far as patching security holes is concerned, once again Google came out on top with average patch time of 53 days, followed by Mozilla with 158 days and Microsoft’s 214 days.

You can see the whitepaper for full analysis of the study.


From auditing to editing, I now test and analyze the latest gadgets and games instead of the latest financial statements. Both jobs are equally intense and rewarding. When I'm not burning up hardware in the name of science, you'll find me nuking in DOTA 2 or engineering in TF2.
