What Computest does
Computest is a Netherlands-based, privately held cybersecurity services firm operating commercially under the DEFION Security brand since its 2005 founding. The company delivers an integrated suite of five security service lines — Security Advisory (including CISO-as-a-Service), Penetration Testing, Managed Detection & Response (MDR), Digital Forensics & Incident Response (DFIR), and Business Continuity — supported by an overlay of continuously updated Threat Intelligence drawn from 40+ sources. Service delivery is anchored by a 24/7 Security Operations Center staffed by 100+ senior in-house security experts (no offshore triage) operating from headquarters in Zoetermeer, Netherlands and a regional office in Barcelona, Spain, with an average customer response time under five minutes.
The underlying technology stack combines offensive security expertise with AI-assisted capabilities: AI-supported signal correlation, automatic Indicator-of-Compromise enrichment, and machine-learning-based alert triage — all wrapped with human decision-making by certified analysts. The firm monitors 100,000+ endpoints across its customer base and serves 1,000+ organizations spanning manufacturing, government, financial services, retail/ecommerce, research/education, technology/SaaS, and critical infrastructure. Notable clients include Dutch municipalities (Gemeente Arnhem), financial institutions (Knab, Hienfeld, OPP), a national lottery operator (Nederlandse Staatsloterij), the SURF consortium covering 75+ Dutch educational and research institutions (jointly with DTX), and a flagship multi-year partnership with AZ football club.
Commercially, DEFION uses a sales-led, consultative enterprise go-to-market with direct field engagement and dedicated account management for major accounts; pricing is quote-based and not publicly disclosed, with MDR delivered as recurring subscription and the remaining lines billed as professional services (annual billing cadence referenced for enterprise agreements). Revenue is generated primarily from European clients, with cross-border delivery via the Barcelona office following the July 2023 acquisition of a majority stake in Spanish cybersecurity firm Incide, a transaction explicitly framed as the foundation for an independent European security platform.

Computest competitors and assessment
Company assessmentBroad incumbents
- Orange Cyberdefense: European MSSP subsidiary of Orange, offering managed security, consulting, and threat intelligence across multiple European markets. Larger and broader portfolio than DEFION but competes directly in the European MDR/DFIR space.
- Trustwave: Global MDR/MSSP and DFIR provider serving enterprises and governments worldwide. Comparable in service portfolio (MDR, DFIR, pen testing, advisory) but operates at significantly greater global scale than DEFION.
- CrowdStrike: Global cybersecurity platform with native EDR/XDR and an expanding MDR/managed services portfolio. Represents the hyperscaler-adjacent, platform-led competitive threat to standalone MSSPs like DEFION.
- Rapid7: Global cybersecurity vendor combining MDR services with its SIEM/EDR/XDR platform. Competes with DEFION in the managed detection layer while leveraging its own software stack, representing a platform-led alternative.

- Northwave: Netherlands-based cybersecurity services firm offering managed security, incident response, pen testing, and advisory. Closely comparable to DEFION on services mix, Dutch mid-market/enterprise focus, and independent MSSP positioning.

- Fox-IT (NCC Group): Dutch-origin cybersecurity firm now part of NCC Group, providing managed security, intelligence, and incident response services. Comparable to DEFION on Dutch roots, MSSP/MDR focus, and European government/critical-infrastructure client base.
- WithSecure: Nordic-headquartered cybersecurity provider with managed detection, incident response, and consulting services across Europe. Comparable on European focus, MSSP/MDR service mix, and independence from hyperscaler ecosystems.
