What Clavister does
Clavister is a Swedish cybersecurity vendor founded in 1997 and headquartered in Örnsköldsvik, Sweden, listed on the Nasdaq First North Growth Market (CLAV.ST). The company develops, tests, and supports all of its technology in Sweden, marketing this European digital sovereignty as a differentiator against non-European competitors such as Fortinet, Cisco, Check Point, and Palo Alto Networks. Clavister serves public sector, defence, energy, telecom, and industrial customers across more than 100 countries, with approximately 120 employees distributed across offices in Örnsköldsvik, Stockholm, Gothenburg, and Munich. Its target verticals are public administration, energy and utilities, telecom, and defence, where it sells into mission-critical environments that must comply with NIS2, GDPR, and NATO interoperability requirements.
The product portfolio comprises three categories. First, Next-Generation Firewalls (NetWall, NetShield, and the military-grade CyberArmour) built on proprietary cOS Core and cOS Stream software. Second, Identity & Access Management (IdAuth, IdAuth Cloud, IdSign, IdSphere) inherited from the 2025 brand unification with PhenixID, which had been wholly owned by Clavister since 2016. Third, Cross-Domain Security (TactiGate XD, co-developed with Saab) for NATO Restricted and NATO Secret environments. Clavister holds a US patent for AI-based cybersecurity technology integrated into CyberArmour, and its products carry Common Criteria and ISO/IEC 27001 certifications (the latter audited by DNV and concluded in 2025). Notable deployments include the Norwegian Defence Material Agency's 280 MSEK Tactical Core Network System (TCNS) contract, BAE Systems Hägglunds, NXP Semiconductors (automotive AI exploration), and European telecom operators securing 5G core infrastructure.
Clavister's revenue model combines subscription-based product licensing for NGFW and IAM offerings (e.g., per-user IdAuth Cloud subscriptions with volume discounts), multi-year development and support contracts with defence agencies (e.g., the TCNS contract, of which approximately 250 MSEK is for development and 30 MSEK for four years of support), and professional services. The company operates a channel-first distribution model anchored by Arrow Electronics, which expanded coverage from Sweden to 11 additional European markets in November 2025, alongside direct enterprise sales for large defence and government accounts such as the NDMA, BAE Systems Hägglunds, and unnamed European defence contractors. In November 2025, Clavister raised approximately SEK 167 million via a directed share issue from European institutional and qualified investors to repay debt and fund growth initiatives.
