Anyone can hack now.
AI can now find and exploit vulnerabilities on its own.

Meet tCell, our offensive agent.
It runs the same attacks on your infrastructure, first.

Chains exploits into working attacks

tCell links weaknesses the way an attacker would. One small gap opens the path to the next, until it reaches something that matters. Scanners see the pieces; tCell finds the route.

Probes your systems like an attacker

tCell signs into accounts, moves between them, and maps your full attack surface. It hunts for cross-tenant leaks, broken isolation, and misconfigured access. It tests like someone with intent would and not like a checklist.

Finds what point-in-time audits miss

tCell routinely finds vulnerability missed by years of point-in-time audits. Your engineering team ships new changes daily; tCell keeps up where ordinary pentests don't.

Security at the speed you ship.

Point-in-time testing and continuous testing

Point-in-time pentesting

Vulnerabilities frozen at audit time.

  • Weeks of setup before testing begins.
  • You receive a PDF report 2 weeks later
  • Patching is your team's problem
  • Fixes are tested again 6-12 months later

Continuous pentesting

Probes your systems like an attacker

  • Easy setup and onboarding
  • Findings show up on the board in real time, as they're found.
  • Antigen opens PRs, your engineers review and merge.
  • Every fix is immediately retested end-to-end.

Find, fix, verify

The lifecycle of a vulnerability

01.

Discover vulnerabilities

Every finding comes with a working exploit

Antigen probes your live attack surface the way an attacker would, chaining weaknesses traditional security scanners report in isolation into paths that actually reach sensitive data.

Every finding arrives with a reproducible exploit attached, so instead of a backlog of hypothetical CVEs, you start with confirmed, exploitable routes.

02.

Remediation and review

Antigen makes your team faster

Antigen writes the fix, opens a pull request with the patch, and updates your project management tool. But nothing merges on its own: the PR routes to your engineers, who review and approve before anything reaches production.

Integrates with

GitHub and Linear

03.

Verification by pentest

tCell reattempts the exploit to verify the fix

In security, fixing a vulnerability often surfaces a deeper, underlying problem. Antigen runs in a loop, so after deploying the fix, tCell reattempts the exploit. If new issues are surfaced, it reopens the vulnerability with detailed logs, and writes a new patch using what it learned.

Experts in the loop

Each customer gets a dedicated security expert.

Hi Tyler, how can I help?

Abdullah Nauman

Your dedicated expert

Book office hours anytime.

Our researchers will hop on a call, walk your team through a finding, or think through your setup with you.

Every report is reviewed by a researcher before it reaches you.

Your expert reviews every vulnerability to prevent false positives, so your engineering team can focus on the vulnerabilities that really matter.
