Who We Are

Cobalt provides the world's largest pentesting platform, delivering thousands of pentests per year. Cobalt's Pentest as a Service (PtaaS) platform is modernizing traditional pentesting. By combining a SaaS platform with an exclusive community of testers, we deliver the real-time insights you need to remediate risk quickly and innovate securely. We see the Pentest as a Service model as a first step in our vision to create a new interface to the security workforce. We have seen tremendous traction over the years and today we have 1000+ customers on Cobalt's platform, ranging in size from Fortune 50 companies to emerging tech start-ups.

We are remote-first with local hubs in Austin, Boston, Berlin, and San Francisco. We have Scandinavian roots, an American base and a global outlook. Our team is characterized by a fun, fast-paced and collaborative culture based on individual responsibility and ownership.

We have secured more than $50M in funding from a variety of top flight investors, led by Highland Europe. We are using our funding to expand global usage and continue development of the Cobalt platform, which pioneered the Penetration test as a Service (PtaaS) model.

You’ll work collaboratively with engineering managers, product managers and engineers to understand the system as a whole and the purpose of the tests, educate on testing best practices, and train engineers with examples and guidelines as they keep new feature development up to our code quality standards.
