Heimdal

Heimdal Security A/S was founded in Copenhagen in 2014 by Morten Kjaersgaard, who moved to chairman when Jesper Frederiksen became chief executive in May 2024; Marlin Equity Partners, a US private-equity firm, has held majority control since March 2020 through Danish holding companies. It claims over 15,000 customers and its registered address and VAT number appear on its own pricing page. Engineering locations are not published and we found no Russian or Chinese link.

Pricing needs a conversation. The pricing calculator on heimdalsecurity.com lets a visitor pick from twelve modules, a customer type (end customer, reseller, MSP or distributor), device and server counts and a currency including pounds, then demands a name, company, job title, email and phone before it will show a figure. We did not submit one, so we have no commercial price. The only fixed pounds prices we could find are Heimdal's listings on the UK Government's Digital Marketplace (G-Cloud 14): £4.00 a device a month, about £48 a year, for a bundle of next-generation antivirus, ransomware encryption protection, patch management and 24/7 SOC monitoring, and £2.98 a user a month for a Unified Threat Platform bundle of DNS security, patching and antivirus with mobile device management. Those are public-sector framework prices, not confirmed as what a small company pays. Trials run 14 or 30 days depending on the bundle. The grid says "Not published".

The platform is genuinely broad for the money it does not publish: Next-Gen Antivirus and Firewall, Ransomware Encryption Protection (which detects encryption without signatures), Patch and Asset Management for Windows, Linux and third-party software, DNS Security at network and endpoint level, Email Security for Microsoft 365 and Google Workspace, Privileged Access Management with automatic de-elevation on detection, Application Control, EDR, XDR and a managed MXDR service, all in one cloud dashboard with a multi-tenant view for MSPs, a documented REST API and integrations with ConnectWise RMM, Autotask PSA and HaloPSA. Windows Server deployment is documented, macOS 10.15 to 14 is listed, Linux is covered for patching. No MCP server was found.

The gap is evidence. Heimdal does not appear in AV-Comparatives' H1 2026 business test, its only AV-TEST result is a 2020 consumer product, we found no SE Labs rating and it did not take part in MITRE's 2025 round. Support on the G-Cloud antivirus bundle is email and ticketing, weekdays nine to five, with a four-hour response and no phone or chat, although the MXDR service has its own 24/7 channel. No breach of Heimdal was found. Trustpilot is 3.8 on 970 unprompted reviews, 4 per cent one-star, though some reviewers appear to be consumers. Not yet tested by Saaskly: assessed on published pricing, the independent test labs, vendor documentation and third-party reviews.
