Picus Security is a cybersecurity company founded in 2013 by Dr. Süleyman Özarslan and Volkan Ertürk and headquartered in San Francisco, California, with offices in Ankara, Turkey and London. Picus is credited with pioneering the Breach and Attack Simulation (BAS) category — a continuous security validation approach that safely simulates real-world cyberattack techniques across production environments to test whether security controls actually block or detect threats as intended. The company's Security Validation Platform maps simulations to the MITRE ATT&CK framework and provides prescriptive mitigation content, allowing security teams to identify gaps and harden their defenses without waiting for a real breach or periodic penetration test.
