HOW IT WORKS

Pentesting Made Easy

Starting a pentest doesn't have to be complicated.
With Cobalt, you're up and running in a few simple steps:

Step 1 CHOOSE YOUR ASSETS

Test every asset. Secure every surface.

Not all assets are equal, but none are low-risk. Select individual assets or set up a program to cover your full environment. Customers use Cobalt to test critical web applications and APIs in production, AI and LLM-based applications still in development, and globally distributed networks segmented by location and business unit.
Step 2 CHOOSE YOUR TESTING MODEL

Flexible pentesting to meet your needs

Every environment is different. Cobalt offers two testing delivery models so you can match the depth and velocity of offensive security testing to your needs. Choose one or the other, or mix and match depending on your assets, environment, release cycles, and goals.

Human-Led

Human-led, AI-powered pentesting remains the most effective approach for uncovering complex vulnerabilities. Leverage purpose-built methodologies and 500+ vetted security experts in the Cobalt Core to find critical exposures in your most important assets.

Autonomous

Autonomous pentesting pairs the speed of AI with elite pentester oversight to deliver actionable, proof-backed findings across your entire portfolio.

Step 3 CHOOSE YOUR FREQUENCY

Control pentesting frequency to reduce exposure windows

Periodic penetration testing meets compliance deadlines. Continuous testing gives you coverage in between. Cobalt gives you the flexibility to blend testing frequencies as your security program and threat landscape evolve.

Continuous

Move beyond point-in-time tests with a continuous pentesting program that combines expert human testing, AI-powered automation, and continuous monitoring to identify exploitable vulnerabilities across applications and infrastructure.

On-demand

Compliance requirements, code releases, and business events all call for different testing frequencies. Schedule pentests on demand whenever you need them. Our planning calendar and credit-based model lets you purchase a block of credits and deploy them as needed.

Some of the issues that come back are phenomenal—things I'd never think of. We're talking chained exploits and complex business logic issues that we could never find internally ourselves. The Cobalt pentesters go deep and find vulnerabilities that a real hacker in the wild could exploit.

Cobalt provides a genuinely collaborative pentesting experience. Our team deeply appreciates the direct access to pentesters working on European hours and the constant communication via Slack. This setup enables us to learn so much, as the pentesters clearly explain their findings and guide us on remediation.
