AI red team for software teams

Hackers now attack with AI swarms. Attack yourself first.

Counterswarm runs a swarm of AI agents against your code, API and app builds on every push and every new threat. Only proven holes reach you, each with a fix you can paste into Cursor or Claude Code.

Why now

Finding a hole got cheap for attackers. Fixing it has to get cheap for you.

AI agents now scan every public app for weak spots, and new vulnerabilities are exploited within hours of disclosure. Big companies have security teams. Most SaaS and mobile teams have nobody watching.

Hours, not days

Critical flaws are exploited within hours of going public. We watch advisories and researcher chatter around the clock and tell you if you are exposed.

Logic bugs scanners miss

The costly bugs are valid code: one customer reading another's data, a free plan reaching paid features. Agents that know your business rules find them.

No security team needed

Plain-English findings, ranked by real exposure, with a fix you can paste. Quiet until something is real.

How it works

Your own swarm, on every change

01 · CONNECT

Two minutes

Install the read-only GitHub app, upload a mobile build if you have one, and tell us who your users and tenants are.

02 · MAP

Learns your app

We map routes, logins, data and money paths once, so every later run is fast and focused.

03 · ATTACK

Swarm on every push

Scouts sweep the change and the code around it; a deep-dive agent proves each lead across files.

04 · VERIFY

Two labs must agree

A model from a different AI company re-checks every finding from four angles. Anything unproven is dropped.

05 · FIX

Paste the fix

You get the file, who can reach it, the evidence and a fix prompt for Cursor, Lovable or Claude Code, by email or Slack.

What the swarm checks

Built for how you ship

B2B SaaS

Tenant isolation, roles and stale access, SSO and sessions, API key scope, webhook signatures, billing bypass.

Mobile apps

Keys hidden in iOS and Android builds, open Firebase and Supabase rules, the real API your app calls, purchase checks.

AI-built apps

Supabase row-level security, service keys in the frontend, public storage, routes missing ownership checks.

AI agent apps

Over-powerful tools, token storage, untrusted content reaching actions, irreversible steps with no approval.

We only ever attack what you own

Read-only

Read-only repo access by default. No secrets, no production data, no changes without your approval.

Your systems only

Live tests run on staging, only after you verify the domain and approve the scope.

Your code stays yours

Throwaway sandboxes, deleted after every run. Zero-retention model providers. Never used for training.

See every action

A full activity log of what was checked, found and ruled out on each run. Pause any time.

Questions

FAQ

Does it replace a penetration test?

It runs continuously and catches most common and business-logic holes between pentests. For some compliance needs you may still want a human sign-off.

Which stacks do you support?

Any web stack and any iOS or Android build. We are tuned for Next.js, Supabase, Node and Python.

What does it cost?

Your first scan is free. Team plans start at $499 a month for up to five repos or apps.

Will it make my app unhackable?

No tool can. It closes the common holes and shrinks your exposure window from days to hours.

Their swarm scans everyone. Yours scans you first.
