Cobalt

Cobalt is a cybersecurity company that pioneered the Pentest as a Service (PTaaS) model, combining a SaaS platform with a global community of security researchers to deliver offensive security solutions. Headquartered in San Francisco, California, the company also maintains offices in Berlin and London, operating with a remote-first approach. Its mission is to empower organizations to operate securely and innovate fearlessly by modernizing traditional penetration testing.

The company's core offerings include a comprehensive offensive security platform that provides application, network, and cloud security services. These services encompass web and API penetration testing, AI and LLM testing, secure code review, automated Dynamic Application Security Testing (DAST), digital risk assessments, red teaming, and attack surface management. The Cobalt platform is designed to streamline pentest launches, facilitate real-time collaboration with testers, enable continuous scanning, and integrate seamlessly with remediation workflows, serving over 1,500 customers.

Recent notable developments include the appointment of cybersecurity pioneer Tony Spinelli to its Board of Directors in April 2026 and earning five industry awards at RSAC 2026 in March 2026. In March 2026, Cobalt also introduced new AI capabilities for continuous pentesting and released its eighth annual State of Pentesting Report. Led by CEO Sonali Shah, Cobalt has been recognized for its rapid growth, securing a spot on the Inc. 5000 list for the fourth consecutive year in August 2024, reinforcing its position as a leader in the offensive security market.
