NFIR (short for Nederlands Forensisch Incident Response) is a Dutch cybersecurity firm built around incident response, digital forensics, and managed detection and response (MDR), backed by a 24/7 emergency response line for organizations actively dealing with a breach. Beyond crisis response, the company offers security testing and ethical hacking, security consulting, and independent digital forensic investigations — services aimed at both preparing for and responding to security incidents.
Founded in 2017 by Arwi van der Sluijs and two co-founders, NFIR has grown from a three-person startup to a team of more than 50 security experts, with offices in Zwolle and the Rijswijk/The Hague area of the Netherlands. The company is a recognized partner of the Dutch national cybersecurity ecosystem, including membership in Security Delta (HSD) and Cyber Veilig Nederland (Cyber Safe Netherlands).
NFIR operates in the incident response and MDR category alongside larger multinational IR firms, but its focus on the Dutch market and its all-Dutch-language emergency response line give it a specific regional advantage for Netherlands-based organizations navigating both an active incident and local regulatory/disclosure obligations. Its growth from three founders to 50+ staff over roughly eight years reflects real organic demand, though independent, named breach case studies with quantified outcomes were not found in public sources.
Innovation Matrix Assessment
Grew from a three-person founding team to a 50+ person specialist firm over about eight years by steadily adding service lines (IR, MDR, forensics, pentesting), a solid but not headline-grabbing pace typical of a bootstrapped services firm.
Provides a genuinely deployable, full incident-response operation with a 24/7 emergency line, MDR, and independent digital forensics — real operational capability rather than a conceptual offering.
Staff growth from 3 founders to 50+ experts and recognized membership in the Dutch national cybersecurity ecosystem (Security Delta HSD, Cyber Veilig Nederland) point to durable regional demand, though no financial figures or major recent catalysts were found.
Incident response and digital forensics is an established service category with many competitors, including large multinational IR firms; NFIR's differentiation is regional focus rather than a novel technical approach.
No independently published, named breach case studies with quantified outcomes were found; efficacy evidence rests on the company's longevity, staff growth, and industry-body affiliations rather than third-party validation.
Incident response and forensic investigation remain essential services, and a Dutch-language, Netherlands-based responder offers a genuine advantage for organizations navigating local breach-notification and regulatory requirements.
Why CISOs Should Care
Gives Netherlands-based organizations a 24/7, Dutch-language incident response and forensics partner familiar with local regulatory and disclosure requirements during an active breach.
What Makes It Different
Combines emergency incident response with independent digital forensic investigation and MDR under one Dutch national-ecosystem-affiliated firm, rather than requiring a multinational IR vendor unfamiliar with local context.
The Matrix Verdict
45/100 — EMERGING / UNRANKED
A credible, steadily-grown regional incident response specialist with real operational depth, appropriately scored as a solid but not disruptive player in a mature service category.
Editorial Note: Claims vs. Verified Findings
Company history (founding year, founder names, staff growth to 50+) and industry affiliations (Security Delta HSD, Cyber Veilig Nederland) are corroborated by the company's own site and partner listings; no independent breach-outcome case studies were found to verify incident-response efficacy claims.
