The Ultimate List Of Cyber Security Gurus You Should Be Following On Twitter

Twitter has become a really great place to find out cyber security information. You can even get insider views on the types of threats as they happen, as well as trends in the cyber security landscape. Instead of waiting for articles or white papers to be written, you can get on-the-fly notice of events. One perfect example of this, was the Twitter feed of Brian Krebs who has made it onto our list.
