These problems are well known, yet enterprise IT management seems to persist in sticking with IE, even spreading disinformation to their employees with claims that FF, Safari, Opera and Chrome are more vulnerable.<p>One incident still boggles my mind. A friend of mind attended a security conference last year with a corporate IT manager who had been insisting that IE is the better choice from a security model standpoint. One after another speaker stood up and presented a paper or a speech or a lecture or a round-table all saying essentially the same thing:<p>The security of networked systems is only as good as it's weakest link, and IE has consistently been the weakest link for years. Even with hundreds of security patches since XP was released, it's still such a threat to the network that it's irresponsible to continue using it. Not one presenter used it anymore. They continued that enterprise IT should not only be recommending other browsers, they should be enforcing other browsers as part of their security policy and disabling IE as much as possible on all systems under their control. It was damning.<p>After we got back to the office, he sent out a corporate wide email reminding everyone that browsers other than IE are vulnerabilities to the network and won't be tolerated.
