What NVISO does

NVISO is a privately held, pure-play European cybersecurity consulting firm founded in 2013 in Brussels by five security professionals. Headcount has grown from the founding team to 300+ specialized experts operating from offices in Belgium, Germany (Frankfurt and Munich), Austria (Vienna), and Greece (Athens), with no disclosed external institutional investors. The firm operates under the explicit mission of safeguarding European society from cyber attacks, and maintains full European data residency and GDPR-aligned operations as a core positioning element.

The company delivers a comprehensive cybersecurity services portfolio organized around three functional axes — Prevent, Respond, and Detect. Services include advisory offerings (CISO as a Service, Governance Risk & Compliance, Secure Development), technical assessments (Penetration Testing, Cloud Security), offensive security (Red & Purple Teaming, including TIBER/TLPT exercises delivered by the ARES research team), managed security services (24/7 Managed Detection & Response, Posture & Vulnerability Management, User-Reported Phishing Response), Security Operations Engineering, Digital Forensics & Incident Response, and Threat Intelligence. The customer base is anchored in European financial services (including SWIFT, BNP Paribas, KBC, Belfius, AG Insurance, AXA, Euroclear), public sector and critical infrastructure (ESA, the European Commission under the MC17 FREIA contract, STIB, Bpost), and large industrial and technology enterprises (Bekaert, Grohe, IMEC, Hexaware).

Revenue is generated through a mix of project-based professional services engagements, recurring managed services subscriptions (MDR, IR retainers with 4-hour on-site SLAs, CISO-as-a-Service retainers), and multi-year framework contracts such as the 2025 EU Commission MC17 FREIA consortium award covering 71 European institutions. The technology stack integrates with Microsoft Sentinel, Microsoft Defender, Microsoft Cloud App Security, Microsoft Purview, Palo Alto Cortex XSOAR/XMDR, ServiceNow GRC, and MISP, overlaid with proprietary tooling maintained by NVISO Labs and the ARES team — including custom command-and-control frameworks, safe ransomware simulation tools, and detection rules for tracked threat families (VShell/UNC5174, BRICKSTORM/UNC5221, SparkCockpit, SparkTar). Approximately 10% of annual revenue is reinvested in research, supporting SANS course authorship (SEC401, SEC560, SEC575, SEC599, SEC699), conference presentations (Black Hat, BruCON, SecAppDev), GitHub-published tools, and MISP threat intelligence contributions. The firm holds ISO/IEC 27001, SOC 2 Type II, Trusted Introducer, BSI APT, EPI PSP, FIRST, SOC-CMM Gold, and Microsoft Cloud Security and Threat Protection accreditations.
