Swiss-domiciled · EU AI Act native · Free to try

Red-team your
AI agents before someone else does.

We built Sixi AI because we kept seeing AI agents go to production without adversarial testing. Point it at your chatbot, MCP server, or A2A endpoint — it runs 285+ attack techniques and maps every finding to EU AI Act articles. You get Article 15 robustness evidence and Article 9 risk management inputs, not a vague risk score.

What It Does

Adversarial testing, purpose-built for AI agents

Penetration testing tools weren't designed for systems that understand natural language. Sixi AI was — from day one.

Thinks Like an Attacker

41 autonomous agents probe for prompt injection, MCP tool poisoning, AI router MITM, indirect content poisoning, data exfiltration, excessive agency, goal hijacking, and EU AI Act Article 5 prohibited manipulation. The same vectors real adversaries exploit — tested systematically.

Swiss-Domiciled. Not Relocated.

Your red-teaming vendor should not be a geopolitical dependency. Sixi AI is Swiss-registered under FADP, outside Five Eyes, with no Cloud Act or FISA 702 exposure. Built for EU AI Act, DORA, and NIS2 from day one. Your assessment data never touches a jurisdiction your legal team has to worry about.

Evidence, Not Opinions

Every finding includes the exact payload, the agent's response, severity scoring, and step-by-step remediation. Auditors get evidence. Engineers get fixes.

Regulation-Mapped Output

Every finding maps to EU AI Act articles (Art. 9, 15, 73), OWASP LLM Top 10, MITRE ATLAS, and DORA. Produces Annex IV §2(g)-ready technical documentation. Built for the teams that answer to notified body auditors, not just engineering.

Any Agent, Any Protocol

REST chatbots, MCP tool servers, A2A agent networks, WebSocket gateways. One tool, consistent methodology, regardless of how your agent is deployed.

How It Works

Three steps. No complexity.

01

CONNECT YOUR AGENT

Provide your endpoint URL and select the protocol — REST, MCP, A2A, or WebSocket. Configuration takes under a minute.

02

SIT BACK

41 attack agents execute 285+ techniques in parallel. Adaptive rewriting generates novel variants on the fly. Go grab a coffee.

03

READ THE REPORT

Article 15 robustness evidence, Article 9 risk management inputs, Annex IV §2(g) technical documentation components. Severity-scored findings with reproduction steps and remediation guidance. Export as HTML, PDF, JSON, or BFSI regulatory report.

About

Independent.
Built with Swiss-grade discipline.

We work in security and AI engineering across Europe — in the industries that cannot afford to get AI wrong. Banking, pharma, enterprise. We built Sixi AI because we kept seeing AI agents deployed to production without adversarial testing, and the EU AI Act deadline was not going to wait.

No VC pressure to ship half-tested features. No sales-driven roadmap. We treat this the way Swiss engineering treats everything: thoroughly tested, cleanly architected, built to satisfy the auditor, not just the developer.

The Team

Three Countries, One Obsession

Security engineers and AI practitioners across the European tech community. Senior people who ship production systems by day — and build the tools to break them by night.

Privacy-first. No exceptions.

Your scan data stays on your infrastructure. No telemetry, no tracking, no data harvesting. We built this the way we'd want it built for our own employers.
