What F3C Systems does
F3C Systems is a Luxembourg-based cybersecurity managed services provider founded in 2018 that serves small and medium enterprises as well as larger corporations across Luxembourg and broader Europe. The company operates a four-pillar service model — Security Audit, Security Infrastructure, Co-management & Security Operations, and SOC & Threat Detection — delivered by a team of 12 specialized professionals. Its primary technical platform is a 24/7 SOC built on the Sekoia XDR engine (a European-sovereign platform with native CTI and 200+ integrations), augmented with AI-driven capabilities for autonomous alert investigation, NLP-based log querying, automated triage and deduplication, and UEBA behavioral detection. Service delivery combines managed security services, professional services engagements, and resale of third-party security hardware and software from partners including Fortinet, Palo Alto Networks, SentinelOne, Splunk, Microsoft, and Sekoia.
The company monetizes primarily through recurring managed-services contracts (SOC monitoring, co-management) and project-based engagements (audits, infrastructure deployments), with multi-year contract cadences and bespoke quote-based pricing. Its go-to-market is sales-led, anchored on an "audit request" intake form on the website, supported by LinkedIn presence, blog-driven thought leadership, and event participation — most notably Nexus Luxembourg 2026, where it co-exhibited with Cegecom (telecom) and Luxcontrol (compliance) at Stand 84. The company holds ISO 27001, Made in Luxembourg, and RSE certifications, and positions European data sovereignty plus regulatory alignment (NIS2, DORA, GDPR, CSSF) as its core differentiator against non-European and generic MSSP competition.

F3C Systems product offering
Product offeringCore offering
F3C Systems sells a managed cybersecurity services portfolio delivered as four integrated pillars: Security Audit, Security Infrastructure, Co-management & Security Operations, and SOC & Threat Detection. The SOC provides 24/7 monitoring powered by the Sekoia XDR platform with SIEM, XDR, EDR, UEBA, and IDS/IPS, combined with deployment and configuration of firewalls, WAF, proxy, segmentation, MFA, and email/web security. Services are scoped per client and primarily delivered under multi-year managed services or co-managed engagement contracts to organizations in Luxembourg and broader Europe.
Product overview
F3C Systems is a cybersecurity services company offering four integrated service pillars: Security Audit, Security Infrastructure, Co-management & Security Operations, and SOC & Threat Detection. Rather than a single software product, the offering is a managed services portfolio — audits assess and prioritize risks, infrastructure services deploy and configure protection tools, co-management embeds F3C experts within client operations, and the SOC delivers continuous 24/7 monitoring via the Sekoia XDR platform. The four services are designed to work together as a cohesive cybersecurity lifecycle: audit informs infrastructure and co-management priorities, infrastructure builds the protective foundation, co-management maintains day-to-day operations, and SOC provides round-the-clock threat detection and response.

F3C Systems competitors and assessment
Company assessmentDirect peers
- Orange Cyberdefense: European MSSP arm of Orange Business, operating SOC/MDR services across multiple EU countries with very similar 24/7 monitoring, incident response and compliance-led positioning (NIS2, GDPR). Most directly comparable competitor to F3C across EU mid-market, but at vastly larger scale.
- Kudelski Security: Swiss-headquartered mid-size MSSP offering managed detection/response, cyber advisory and managed security services to European enterprises and high-net-worth verticals. Closest peer in scale, scope and European sovereignty positioning; comparable to F3C's mix of SOC, audit and infrastructure services.
Emerging players
- Sekoia.io: European XDR/MDR platform vendor whose Sekoia XDR product powers F3C's SOC. Sekoia itself runs partner-enabled MSSP programs that overlap with F3C's service line, making it both core technology partner and partial competitor on the MSSP layer.
- HarfangLab: European (French) cybersecurity vendor specializing in EDR/XDR with a growing MSSP/MDR partner ecosystem. Competes with the platform layer that F3C builds its services on and partially overlaps on managed detection.
Broad incumbents
- Sopra Steria Cybersecurity: Major European IT services group with a large cybersecurity practice offering SOC, identity, compliance and managed security across public and regulated sectors. A broad incumbent competitor to F3C in Luxembourg and Benelux enterprise accounts.
- Devoteam Cybersecurity: Pan-European IT consultancy with a dedicated cybersecurity service line covering managed detection, cloud security, identity and compliance. Competes with F3C for EU mid-market and enterprise cyber mandates and shares a similar partner-channel GTM motion.
- Capgemini Engineering (Cybersecurity): Global systems integrator with extensive cybersecurity capabilities including managed SOC, identity and compliance services. Overlaps with F3C in regulated European sectors but operates at significantly larger scale and with broader geographic reach.
Regional players
- POST Luxembourg: Luxembourg's incumbent telecom operator offering cybersecurity services including SOC and managed security to local enterprises and institutions. Direct regional competitor and adjacent infrastructure provider in F3C's home market.
- Proximus Cybersecurity: Belgian telecom-group cybersecurity arm delivering SOC, managed security and compliance services across Belgium and Benelux. Comparable regional competitor targeting SME/enterprise segments in adjacent jurisdictions.
Others
- Cegecom: Luxembourg telecommunications operator and F3C's strategic co-marketing partner at Nexus Luxembourg 2026. Included as an ecosystem adjacent rather than direct MSSP competitor, but a key cross-sell and connectivity infrastructure partner that shapes F3C's distribution.
