How Aaron is building a better working world 

Empathy. By truly putting yourself in the shoes of a Chief Information Security Officer (CISO) who has to report progress every quarter; a Security Operations Center (SOC) manager who has to wake up early and go to bed late at night due to the global threats the company is facing; or a new employee who is eager to explore and learn more about cybersecurity, you start to see the world of business working better together.
