We built Sixi AI because we kept seeing AI agents go to production without proper adversarial testing. Point it at your chatbot, MCP server, or A2A endpoint — it runs 134+ attack techniques and maps every finding to EU AI Act risk categories. You get a compliance-ready report, not a vague risk score.

What It Does
Penetration testing tools weren't designed for systems that understand natural language. Sixi AI was — from day one.
26 autonomous agents probe for prompt injection, data exfiltration, excessive agency, and goal hijacking. The same vectors real adversaries exploit — tested systematically.
Every finding includes the exact payload, the agent's response, severity scoring, and step-by-step remediation. Auditors get evidence. Engineers get fixes.
REST chatbots, MCP tool servers, A2A agent networks, WebSocket gateways. One tool, consistent methodology, regardless of how your agent is deployed.
Findings map directly to OWASP LLM Top 10, MITRE ATLAS, and EU AI Act articles. Built for the teams that need to answer to compliance, not just engineering.
How It Works
Provide your endpoint URL and select the protocol — REST, MCP, or A2A. Configuration takes under a minute.
26 attack agents execute 134+ techniques in parallel. Adaptive rewriting generates novel variants on the fly. Go grab a coffee.

Use Cases
If your AI agent interacts with users, handles sensitive data, or operates in a regulated industry — it needs adversarial testing. Not next quarter. Now.
AI advisors, fraud-detection bots, trading assistants. If it touches FINMA-regulated workflows, it needs adversarial testing.
FINMA · EU AI Act High-Risk
Clinical data agents, drug-interaction checkers. Swissmedic GxP data integrity applies to AI systems too.
Swissmedic · GxP
Triage chatbots, diagnostic assistants, patient portals. Catch hallucinated medical advice before patients see it.
BAG · Art. 14 Oversight
Customer chatbots, internal copilots, MCP tool servers. If users can talk to it, it should be tested.
SOC 2 · ISO 27001
Citizen-facing AI assistants, policy chatbots. Evidence-backed assessments with nDSG and EU AI Act mapping.
NCSC · nDSG
Shopping assistants, recommendation engines, support bots. Prevent goal hijacking and price manipulation.

About
By day, we work in security and AI engineering across Europe — in the industries that can't afford to get AI wrong. Banking, pharma, enterprise. On evenings and weekends, we build Sixi AI — because we kept seeing AI agents deployed to production without adversarial testing, and the EU AI Act deadline wasn't going to wait.
We treat this the way Swiss engineering treats everything: thoroughly tested, cleanly architected, built to satisfy the auditor, not just the developer. The only difference is we get to choose the problem — and this one matters.
The Team
Three Countries, One Obsession
Security engineers and AI practitioners who met through the European tech community. Weekdays: our respective employers. Weekends: making AI agents harder to break.
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.
