Hoboken, NJ, November 17, 2021 — Semperisthe pioneer of identity-driven cyber resilience for enterprises, today announced it ranked No. 62 on the Deloitte Technology Fast 500™, a ranking of the 500 fastest-growing technology, media, telecommunications, life sciences, fintech, and energy tech companies in North AmericaFor the second year in a row, Semperis ranked among the top 10 fastest-growing companies in the greater New York area. Semperis continues to expand its global presence and accelerate hiring across all departments to support market demand for comprehensive hybrid Active Directory threat mitigation and rapid response solutions.  

 “Our designation in the Deloitte Fast 500 for the second year is testament to rapid adoption from the market, which was driven by our work on the front lines fighting back against the cybercrime wave that is flooding the world right now,” said Mickey Bresman, CEO of Semperis. “For example, Semperis is helping multiple healthcare providers that have been hit by ransomware attacks and have lost control of their environments—with devastating effects on their ability to deliver patient care. We help those companies rebuild their infrastructures as fast as possible, regain control by removing the adversary, and close security gaps so they can trust their environment again.” 

Cyberattacks targeting Active Directory, the identity system used in 90% of organizations worldwide, are on the upswing. Attackers take advantage of weak Active Directory configurations to identify attack paths, access privileged credentials, and deploy ransomware. To help organizations stay ahead of cybercriminals, Semperis recently announced its latest release of Directory Services Protector (DSP), which provides a complete picture of exposure in hybrid environments by monitoring for threats in both on-premises Active Directory and Azure Active Directory in one view.

“Each year the Technology Fast 500 shines a light on leading innovators in technology and this year is no exception,” said Paul Silverglate, vice chair, Deloitte LLP and U.S. technology sector leader. “In the face of innumerable challenges resulting from the pandemic, the best and brightest were able to pivot, reinvent and transform and grow. We celebrate the winning organizations and especially the talented employees driving their success.”
