About Cobalt

Cobalt offers a full suite of offensive security services, from autonomous pentesting to human-led pentesting. The Cobalt Offensive Security Platform helps customers move beyond point in time pentesting to a continuous offensive security program.[1][3]

Cobalt says most pentesting programs still operate on an annual cycle. Cobalt describes the gap between how fast risk changes and how often organizations test for it as the exposure adversaries count on.[7]

The Cobalt Platform centralizes access to the full range of security testing services: web app, API, cloud, network, red teaming, AI and LLM, and more. Customers can launch a pentest in hours and get real-time findings. Customers can collaborate directly with testers via the platform, Microsoft Teams or Slack. Cobalt says Cobalt Sage AI powers every Cobalt pentest and is built on 13 years of expertise, informed by thousands of security engagements. Cobalt says Cobalt Sage AI removes the reconnaissance, scanning, triage and reporting work so human experts can focus on complex attack paths and creative scenarios.[1][3][4][7][10]

Cobalt delivers penetration testing across the entire application portfolio to find and fix vulnerabilities before they are exploited. Cobalt says network and cloud infrastructure are high-value targets in a constant state of change, and that Cobalt identifies and validates real exposures across the attack surface.
