RedSwarm

Autonomous offensive testing for web applications and APIs.

RedSwarm autonomously maps, attacks, and validates vulnerabilities in your web applications and APIs. Every confirmed finding includes reproducible evidence, such as the triggering request and confirming response or out-of-band callback. Scope, logging, and a kill switch are agreed and tested before the first request is sent.

Web applications and APIs · Scoped to your environment

The problem

A pentest describes the application you shipped that month.

Code ships weekly; a point-in-time engagement reports once. Between engagements, new endpoints and changed authentication flows go untested, and the result arrives as a PDF weeks after the test.

A new API route ships and is never added to a test scope.

A scanner reports hundreds of pattern matches with no evidence of which ones are exploitable.

Findings reach engineering weeks after the test, as a document instead of a ticket.

An unscoped AI model cannot be pointed at production: no audit trail, no blast-radius limit, no way to stop it.

Scope

What RedSwarm tests

Web applications and APIs, tested by active exploitation. A pattern match alone is never reported as a finding.

Attack surface discovery

Endpoints are mapped before any attack runs, including undocumented and legacy routes.

Vulnerability classes

Tested with real requests against the target: injection, broken authentication, broken access control, SSRF, XXE, XSS, insecure deserialization, security misconfiguration, sensitive data exposure, and cryptographic failures.

Blind vulnerabilities

Out-of-band callbacks, correlated to the scan session, confirm blind SSRF, blind XXE, and Log4Shell-class issues where the application shows no visible output.

Multi-model swarm

Several AI models plan and run attacks against the same target. A result proposed by one model is cross-checked by others before it is reported, to reduce false positives from any single model.

Methodology

How it runs

Five steps, from signed scope to tickets in your backlog.

Authorize

Scope is signed off. Blast-radius limits and the kill switch are tested before any traffic is sent.

Discover

The attack surface is mapped: endpoints, parameters, and authentication flows.

Attack

A planner selects attack vectors for each target and interprets responses; an executor sends the requests.

Validate

A finding is reported only when there is confirming evidence. The triggering request and the confirming response or out-of-band callback are stored with the finding.

Deliver

Each finding becomes a Jira, GitHub, or GitLab ticket with CVSS, CWE, and OWASP mapping. Slack, PagerDuty, and webhook notifications are available.

Two different targets

RedSwarm tests the application. The assessment tests the agent.

RedSwarm

Autonomous exploitation-style testing of web applications and APIs, with confirmed, reproducible findings.

AI Agent Security Assessment

Adversarial testing of an AI agent: its tools, its authority, and the action paths attacker-controlled input can open.

They are independent. An agent with sound authority boundaries still runs on APIs that can be broken, and the reverse.

Deliverables

What you receive

Finding tickets with proof

The triggering payload and the confirming evidence (response or out-of-band callback), reproducible by your engineers.

Action log

Every request RedSwarm sent, reviewable by your security team or an external reviewer.

Framework cross-references

Findings include relevant security-framework and regulatory cross-references where applicable (for example SOC 2, ISO 27001, HIPAA, GDPR), for use in your own compliance work. They do not establish compliance on their own.

RedSwarm deploys as Docker inside your network; air-gap deployment is available. Which models run, and where, is agreed as part of the scope. We recommend a staging environment for the first run.

Why Themis

Why RedSwarm

Proof, not pattern matches

Nothing is reported without confirming evidence. Engineers receive the request that reproduces the issue.

Governed by design

Every action is scoped, logged, and stoppable. Scope is signed off and the kill switch is tested before any traffic is sent.

Historical RedSwarm results

First finding in 39 minutes (API surface of an APAC insurance group); first confirmed vulnerability in 52 minutes (a port operator with 46 member units). 2,374 confirmed findings across 847 scan sessions. Historical RedSwarm platform data, through April 2026.

FAQ

Questions we get asked

Is this a pentest?

RedSwarm performs active exploitation-style testing and delivers confirmed findings as engineering-ready evidence. It complements, but does not replace, human-led testing where manual review, compliance, or specialized expertise is required.

Is it safe to run against production?

Scope, blast-radius limits, and a kill switch are agreed and tested before any traffic is sent, and every request is logged. We recommend staging for the first run.

Does it test AI agents?

No. Security testing of AI agents is handled by the Themis AI Agent Security Assessment. RedSwarm focuses on the applications and APIs around them.

How is it priced?

Pricing is scoped to your environment: the number of applications and how often they change. We do not publish a tier price.
