About Guardsix

Guardsix is a European security company that sells a sovereign security platform for lean defenders, with products for SIEM, NDR, SOAR, fleet management and access governance.[1][14]

Guardsix says its platform is aimed at European organisations that protect society, such as energy, healthcare and public services, and the partners who serve them. Guardsix says cloud-first security shifts control away from defenders while leaving accountability behind, and says it closes that gap by giving customers control over their data, deployment and operations. Guardsix says it designs for European legal and operational requirements, partners with regional cloud providers, and offers on-prem and sovereign-ready deployments. Guardsix offers on-demand or instructor-led training to help analysts grow from day one.

Guardsix SIEM is for lean teams defending Europe in energy, healthcare and government, and for the MSSPs who serve them. Guardsix says it delivers sovereign log management across hybrid, on-prem, OT and cloud environments, and continuous audit-ready evidence for NIS2, DORA and GDPR Article 32. Guardsix SIEM is self-hosted and air-gappable, and its pricing is node-based, so spend scales with the infrastructure rather than with data volume. Content packs aligned with NIS2, DORA and GDPR requirements are ready to use. Guardsix SIEM brings logs from IT estates, OT environments, identity systems, network devices and applications into a single instance that the customer controls.[7][9][11]

Guardsix NDR pairs with Guardsix SIEM as one platform with a chain of events across IT and OT. Guardsix says it uses machine-learning analytics and stitches related signals into a timeline across the seven phases of an attack. Guardsix says Guardsix NDR is designed so any analyst on a lean team can use it productively from day one. Guardsix SOAR is the automation and response layer of Guardsix SIEM, and its playbooks execute locally. Alerts from Guardsix SIEM and NDR enter SOAR with full context already attached, and Guardsix SOAR can expand with hundreds of additional integrations across EDR, identity, cloud and OT.[9][10]

Guardsix Governance for Healthcare gives hospital IT and compliance teams the visibility, reporting and audit trails that healthcare regulators expect. Guardsix says the access control model it built first for healthcare applies to any regulated environment where access has to be visible, explainable and defensible.[12]

Guardsix describes two audiences. For critical national infrastructure operators, Guardsix says it helps them. Guardsix points to hospitals, energy grids, water management and transportation as systems whose failure harms communities. Guardsix says it prices by the number of nodes, devices or entities in an environment.[13]

Guardsix was formerly Logpoint, which officially announced its transformation into Guardsix on March 12, 2026. Guardsix traces its history to a company founded in Denmark as a cybersecurity consulting business. Swedish investment firm Summa Equity acquired a majority stake in Logpoint, and Guardsix names Summa as its majority investor. Logpoint acquired the Danish cybersecurity company Muninn, specialised in AI-driven NDR. Logpoint also acquired the Israeli company SecBI, specialising in SOAR, XDR and automated threat detection. Mikkel Drucker joined Logpoint as CEO. Guardsix A/S carries the company reg. no. 26 30 19 39, and Guardsix says it is EU-HQ and EU-governed.[1][2][5][10][11][12]
