About Us

Zyston is an information security solutions company providing businesses the comprehensive range of end-to-end services required to build and operate mature, cost-effective information security programs.

Our Story

A Zyston (properly spelled Xyston in ancient Greek) was a warfare innovation used by the Macedonian army under conqueror Alexander The Great. A type of long thrusting spear, the Xyston extended several feet longer than the typical enemy spear, giving the army a more aggressive offensive weapon that extended the long range of its military force.

At Zyston, our tireless approach to innovation and development gives our clients the aggressive weapon needed to combat the many cyber threats that exist today. Whether you choose Zyston for Advisory Services, Human Capital Delivery, MSSP(e), or all three, you will be out in front of your enemies.

Keyvan Bohlooli


“We partnered with Zyston to build and mature our security team.  Zyston was successful in recruiting the current CISO as well as the Head of Security for my team.  I found them to be very resourceful, accommodating, and very good communicators. I would highly recommend them to anyone looking to build a successful environment.”
