Heimdal is a Danish security company based in Copenhagen that sells a single unified platform to organisations, mostly mid-sized ones and through managed service providers. It is younger than most vendors here and grew from one idea — stopping threats at the DNS and patch layer, before anything needs to be detected on the endpoint — into a broad suite. The range is modular and each module carries the company name: Heimdal DNS Security, Heimdal Patch & Asset Management, Heimdal Application Control, Heimdal Ransomware Encryption Protection, Heimdal Email Security and Heimdal Email Fraud Prevention, with Heimdal Privilege Elevation & Delegation Management and Heimdal Privileged Account & Session Management covering administrative rights. Detection and response run from Heimdal Endpoint Detection & Response up through Heimdal XDR and the managed Heimdal MXDR. Its positioning is European compliance — NIS2, GDPR, ISO 27001 — and prevention rather than detection, which is worth bearing in mind when comparing it here: much of what it sells is designed to act before the point at which a detection test measures anything.
