About Us
We Humanize Security Testing.
Founded in 2018, Simuna Infosec is built on a simple conviction: every major breach involves a real human attacker — so real human experts are what it takes to stop them.
Our Story
Simuna Infosec was founded in October 2018 by a group of industry experts who saw the same problem repeating: automated scanners were being sold as "penetration testing," leaving enterprises with a false sense of security and undiscovered critical vulnerabilities.
We built Simuna on the opposite principle. We rely on human intelligence for security testing. We understand that AI and automated tools, however advanced, cannot yet replicate the creativity of a skilled attacker probing your business logic. So we assembled a team of offensive security specialists and built proprietary testing methodologies and in-house test cases that commercial scanners simply cannot replicate.
Seven years later, we've delivered 500+ projects for 50+ enterprise clients across four continents — securing telecom platforms, banking systems, automotive infrastructure, and government smart-city initiatives.
