Profile bio

About Brian Maier

My interests in Cyber Security is very high are both professional and personal. Specializing in the Ethical Hacking, Penetration Testing, Cisco Networking, Red team, Blue Team and general Security practices. Why react, when you can identify and prevent a vulnerability before it happens. Knowledge is power, and if you know your weak points, you know where to create better defenses. Call it Tiger team, Purple Team, or threat hunter, all of these are applicable.When we all do our part as part of well defined organization, it is amazing to what it can become. Call me patriotic, but one less risk is one less vector against ourselves, our work, and our nation. Cybersecurity is a must, otherwise the inevitable cyber destruction will happen.
