Enterprise Cyber Resilience


TenEight applies best in class processes developed in collaboration with academia to help organizations recover from cyber incidents, define cybersecurity strategy, assess security maturity, lead improvement projects and obtain security certifications, such as CMMC.

TenEight is founded by Greg Crabb, who developed proven methods to deliver resilient and secure national critical infrastructure. For six years, as Postal Service CISO, he applied these methods to protect its technology and information assets against nation state threats; including the protection of military mail and the 2020 US elections. Independent of organization size and technology stack, these process improvement methods assure secure, resilient and compliant systems. Greg’s 25 years in law enforcement, risk management and cyber security leadership give him a distinct perspective on enterprise challenges.
