About HackHeart
In short
HackHeart is an independent offensive security firm founded by Sébastien De Coninck, a penetration tester based in Sophia Antipolis on the French Riviera. HackHeart performs web, API, infrastructure and Active Directory penetration tests and develops its own multi-agent AI-assisted pentesting platform.

Before cybersecurity, Sébastien De Coninck worked in B2B sales. He kept one conviction from it: a pentest report only has value if decision-makers understand it and act on it.
Why HackHeart invests in AI
Time is the scarcest resource in a penetration test. HackHeart therefore built Umbra, a platform where specialised AI agents handle exploration and first-pass analysis, then challenge each other to eliminate false positives before the tester validates. The goal is not to replace human expertise but to extend its reach.
