Value proposition
Replaces one-off penetration-test audits with continuous, AI-driven offensive security. AI agents map the attack surface, find vulnerabilities, prove exploitability, support remediation and re-test fixes. The work takes hours rather than weeks, at lower cost, on European infrastructure.
Products and solutions
Agentic AI pentesting platform built on five pillars: exposed-asset mapping, vulnerability identification, exploitability demonstration with proof of compromise, remediation support (prioritization and tool integrations), and automated re-testing with fix verification. The platform runs two AI agents, Emile and Champollion. The company also offers a free exposure check and a compliance cost calculator.
Unique value
A European, sovereign alternative to US autonomous-pentest agents. It is EU-hosted (on Scaleway) and multi-tenant, and every finding comes with proof of compromise plus automated remediation verification.
Target customer
European companies of all sizes. This includes SMEs that lack resources for regular pentests and enterprises in regulated sectors facing NIS2 and sovereignty requirements.
Industries served
Cybersecurity, regulated industries (financial services, insurance, SaaS), enterprises subject to NIS2
Technology advantage
Multi-agent offensive AI (Emile and Champollion) backed by the founders' pentesting expertise. Continuous attack-surface monitoring triggers re-tests whenever systems change. All agents run on European infrastructure, which addresses sovereignty needs for regulated buyers.
How they differentiate
EU-hosted and sovereign by design, positioned as the European alternative to US players such as XBOW. It covers the full loop from discovery through exploit proof to remediation verification, rather than one-off tests or scanning alone.
