Cobalt

Cobalt transforms traditional penetration testing into a dynamic, tech-enabled experience through its Pentest as a Service (PtaaS) platform. You can move away from slow, static PDF reports and instead launch comprehensive security assessments in days rather than weeks. The platform connects you directly with a vetted community of on-demand security researchers who test your web applications, APIs, and cloud infrastructure in real-time.

You can manage the entire testing lifecycle from a single dashboard, allowing your developers to communicate directly with testers for faster vulnerability remediation. It integrates with your existing development workflows to ensure security keeps pace with your release cycles. Whether you need to meet compliance requirements like SOC2 or harden your external attack surface, you get actionable data and on-demand retesting to stay secure.
