The good news is that most companies found out that they didn’t have the bug. Windows IIS servers are immune to it as they don’t rely on the OpenSSL libraries that are the heart, no pun intended, of the Heartbleed issue. Many Unix and Linux-based webservers run older implementations of OpenSSL that are also not vulnerable to Heartbleed. Many servers have a lot of issues with SSL that are unrelated to this latest vulnerability. One of the biggest ones is the use of older SSL protocols that have long been obsolete and shown to be exploitable.
