WithSecure Labs

Formerly F-Secure Labs; Finnish; strong on European threat actors. Cadence is sparse (low-frequency rotation source). The /publications landing does NOT surface per-post dates. Drill rule: open the most recent 3 posts on the landing and read their byline date inside the article. Reliability MEDIUM due to publication frequency, not quality. | 2026-06-20 full audit (v2.62): URL MOVED — labs.withsecure.com/publications now 301s to www.withsecure.com/en/resources-hub/w-labs/ (WebFetch won't auto-follow the cross-host 301). url updated. Sparse cadence; drill into per-publication pages for dates.
