01Find
We test it the way AI-powered attackers do.
AI-assisted testing at attacker speed, verified by senior engineers.
Attackers have AI now. Your defense should too.
With generative AI, attackers exploit flaws in hours. We find yours first, fix them and harden the AI you ship.
02Fix
Ranked by real risk. Fixed in your code.
Exploits now show up within hours. Every finding comes with a fix we ship with your team.
03Harden
Ready for attackers that never sleep.
We retest every fix and leave AI-specific tests running.

Cutting-edge security, backed by SONNET CODE.
We test AI because we build it.

Recent attacks
Generative AI changed how attacks happen.
Public cases from the last year: faster, more automated and aimed at AI itself.
Oct 2026
PHP2Shell: found by AI, exploited within hours
AI helped find two critical flaws in PHP, which runs most of the web. Attackers tried them before the disclosure and at scale right after.
What it means Patch windows are now measured in hours.

- Oct 20 Flaws announced
- Oct 21 Patch out, broad exploitation attempts
An attack agent that runs on stolen AI
Symantec caught an agent that hijacks exposed AI models to run intrusions on its own, for up to 100,000 steps without a human.
What it means Your exposed AI can become the attacker's engine.
Source: Help Net SecurityThe first AI-orchestrated espionage campaign
Anthropic stopped a state-backed campaign against about 30 organizations in which AI did 80 to 90% of the work.
What it means One operator with agents works like a whole team.
Source: AnthropicMalware that asks AI what to do next
Google saw APT28 use malware that asks a generative AI model for commands in the middle of a live attack, a first.
What it means Signature-based defenses miss attacks that write themselves.

Most security playbooks were written before generative AI.
That's where we come in: cutting-edge security, built for attackers that use AI.

When your stack is in the news
A flaw like PHP2Shell hits your stack and you need to know today if you're exposed.
Vulnerability AssessmentBefore shipping an AI feature or agent
Your product uses generative AI or runs agents, and nobody has tried to break it yet.
Generative AI SecurityWhen more of your code is written by AI
Assistants write code fast, and slip in insecure patterns. We review what ships.
Security Code ReviewBefore an enterprise security review
Customers now ask how you secure your AI. Have the answers ready.
Penetration TestingHow it works
From scope to retest.
