The term "We take security seriously" has almost become a joke. Every corporation or company throws it around. Recently on a vulnerability disclosure, a megacorp stated that very line but then proceeded to hide critical details and handle things poorly.

What is the sniff test for you when deciding if a company actually does in fact take security seriously?

Also, what companies are more progressive and are actively pushing security as a differentiator? I seem to remember a company recently that not only had 3rd party code audits performed but they even disclosed details of what the auditor found. I cannot however recall the name.

Thanks
