SerSo

What SerSo does

SerSo is a Belgian managed IT services provider founded in 2008 and headquartered in Lummen (with a registered entity in Bilzen), operating primarily in the Limburg region. The company delivers a unified portfolio spanning cybersecurity (security audits, ethical hacking, continuous monitoring, incident response, NIS2 advisory), IT support (all-in helpdesk subscriptions with unlimited user requests, on-site support, proactive monitoring, and temporary or permanent IT outsourcing), networking (firewalls via WatchGuard, segmentation, WiFi, secure remote access), and cloud and infrastructure services built around Microsoft 365, Teams, SharePoint, and Azure, with servers and infrastructure hosted in Belgium. The core technology stack is composed of third-party best-of-breed products integrated and managed by SerSo (Microsoft, SentinelOne, WatchGuard, Duo MFA, Phished, N-able, HPE) rather than proprietary platforms, augmented by an in-house AI-assisted mail triage capability that flags urgent support emails to the team.

SerSo sells primarily to Flemish SMEs (kmo's) either lacking an internal IT function or seeking supplementary capacity for an existing IT team, and increasingly to organizations facing NIS2 compliance obligations. Its go-to-market is consultative and field-sales driven, beginning with a free intake meeting, followed by a tailored roadmap and proposal. Commercial mechanics combine all-in recurring subscriptions (the core revenue driver) with project-based professional services for audits, migrations, and VLAIO-subsidized cybersecurity improvement trajectories. As an official VLAIO partner with KMO-portefeuille registrations (DV.O243319, DV.A110299) and ISO 9001 / ISO 27001 certifications, SerSo can offer Flemish SMEs up to 50% subsidy on its cybersecurity programs, providing both a regulatory qualification advantage and a subsidized demand channel. The company is founder-owned and privately held with no disclosed external funding rounds, parent company, or M&A activity, and operates as SERSO BVBA under Belgian law.
