Our take
Founded by experts from the US Military’s Cyber Command and MIT Lincoln Laboratory, SimSpace is a cyber training platform that provides users with simulations, training exercises and rehearsals that act as stress tests for the cyber security of tech and its users.
At a time when cybersecurity is becoming a military and corporate priority, SimSpace’s Cyber Force Platform helps train sophisticated tech enterprises, governments and national infrastructure companies to become more resilient. Its comprehensive medley of stack optimization tools, attack simulations, actionable analysis, and “live fire” exercises are built to both strengthen cybersecurity and increase the efficiency of a company’s tech.
With the founding team's background in the military and government research and development sectors, the company has a good foundation of expertise surrounding its target market. Substantial funding from L2 Point, that was awarded in 2023, is also aiding its growth as it accelerates expansion into new territories.
