Picus Security
Picus Security is an Ankara-founded cybersecurity company that built one of the earliest commercial breach-and-attack simulation (BAS) platforms — software that continuously runs safe, controlled attack techniques against an enterprise's production environment to see which ones are actually detected and blocked by the deployed security stack. Instead of trusting vendor claims, security teams get a measured, MITRE ATT&CK-mapped view of where their SIEM, EDR, firewalls, and email gateways are silently failing. Founded in 2013 by Alper Memiş and Volkan Ertürk, Picus has raised over USD 80 million from Turkvent, Earlybird, and Mastercard Ventures among others, and is regularly named a leader in Gartner's security validation and exposure management categories. It is one of the most internationally credible Turkish cybersecurity companies and a strong example of the region's deep-tech security talent.
