About

We protect the software supply chain.

O3 Security is the only platform that traces a supply chain attack from the vulnerable line of code that introduced it to the exploit happening in production — across every stage of the SDLC.

Our mission

Modern software is assembled, not written. Every dependency, container image, and CI pipeline step is an attack surface. We built O3 because existing tools catch vulnerabilities but miss attacks — they tell you what's wrong, not how a real adversary would exploit it.

Our mission is to give every engineering team the same adversarial visibility that offensive security researchers have — automated, continuous, and integrated into the workflows they already use.

Our story

Founded by security researchers who lived through supply chain attacks firsthand.

The founding team spent years doing offensive security — red teams, Black Hat research, CVE discoveries — watching organizations get breached through vectors that existing scanners would never catch.

Supply chain attacks succeed because defenders think in terms of known vulnerabilities, not attacker kill chains. We built O3 to close that gap: a platform that reasons about how an attacker would move through your software supply chain, not just whether a CVE score is high enough.

How we work

Security that actually ships.

Security first

Every product decision starts with one question: does this make the attacker's job harder? We don't ship features that look good in demos but miss real attack vectors.

Ship fast

Security tools that ship quarterly can't protect teams that ship daily. We move at the pace of the teams we protect — and we expect the same from our own engineering.

Think adversarially

We build with an attacker's mindset. Our researchers have presented at Black Hat, filed CVEs, and contributed to open-source security tooling trusted by thousands of teams.
