Erium

What Erium does

Erium is a French cybersecurity company founded in 2011 and headquartered in Paris, with offices in Rennes (R&D), Bologna (Italy), and Doha (Qatar). The company develops two core platforms under the BlackNoise brand: BlackNoise AEV (Adversarial Exposure Validation), a Breach and Attack Simulation (BAS) platform that simulates more than 2,000 adversarial behaviors across endpoint and cloud environments (Linux, Windows, macOS, AWS, Azure) to measure MTTD/MTTR/MTTA metrics and automatically generate Sigma/Yara/Suricata detection rules; and BlackNoise HRM (Human Risk Management), an immersive cyber training and behavior measurement platform with native AI/LLM integration for generating bespoke training content. The two platforms share a REST API architecture for integration with SIEM/XDR/SOAR infrastructure and Learning Management Systems, and target enterprise CISOs and SecOps teams facing regulatory pressure from DORA, NIS2, TIBER-EU, and PCI DSS mandates.

Erium operates a subscription-based software model with both SaaS and on-premises deployment options, complemented by professional services including custom API connector development, proprietary adversarial behavior development, technical certification training, crisis exercise facilitation, and bespoke training programme design. The company sells primarily through direct enterprise sales with a structured MSSP and consultancy Partner Programme, supported by thought leadership through the annual BlackNoise Barometer and Annual Report. Its 200+ customer base spans banking (BPCE, Société Générale), retail (Carrefour), luxury goods (Hermès), industrial gases (Air Liquide), insurance (Malakoff Humanis), building services (EQUANS), e-commerce (Mirakl), flooring (Tarkett), and government (European Parliament, CVRIA).

The 50-person team is led by Chairman Florent Skrabacz, CEO Arnaud Le Men, CTO Pierre Texier, and COO Emilien Marimpouy. Erium participates in France 2030 national cybersecurity programmes (CYBAS consortium with BreacHunt, GATEWATCHER, HarfangLab, and Snowpack; CYBR-H with Anozr-way), joined the European Cyber Security Organisation (ECSO) in June 2023, and was selected as a Gartner Representative Vendor in the Market Guide for Adversarial Exposure Validation 2026.
