Break it. Build it.
Ship it secure.
Pentesting, infrastructure hardening, and DevSecOps — from the team that finds the vuln and writes the fix.
What we do
Penetration Testing
Web apps, APIs, infrastructure, cloud. Manual testing backed by automated tooling. We find what scanners miss.
Infrastructure Hardening
Remediation delivered as Infrastructure as Code you can actually deploy. Not a report — a commit.
DevSecOps & Tooling
Custom scanner pipelines, SAST/DAST integration, security gates baked into your workflow.
How we work

Autonomous Security Agents
We're building autonomous security agents that deploy directly into your infrastructure, paired with real-time dashboards for continuous visibility into your security posture.
Built by builders.
Broken by experts.
We met in college, but our interests pulled us to opposite sides. One spent every free hour breaking into systems, the other building and defending infrastructure.
We kept seeing the same problem: scan reports buried in noise, manual triage eating weeks, and critical CVEs lost in spreadsheets. The gap between finding a vulnerability and actually fixing it was broken.
So we built DualStack.
Two-person firm by design — no account managers, no handoffs, no noise. You talk directly to the engineers doing the work. That means faster turnaround, deeper context, and fixes that actually ship.
