HYAS Infosec

Steady expansion from a DNS-security point product into a public-sector-focused platform via its Carahsoft partnership, plus continued threat-intelligence investment over a decade, though not an unusually fast release cadence.

Pairs a genuinely differentiated adversary-infrastructure mapping capability (HYAS Insight) with the protective DNS product, giving customers both a blocking control and an investigation and attribution tool most DNS-security-only vendors don't offer.

Roughly $48 million raised over four rounds and a public-sector channel partnership are solid but modest for a company a decade old; it remains a relatively small, privately held player of roughly 27 employees rather than showing hypergrowth.

Protective DNS itself is an established category alongside vendors like Cisco Umbrella and Infoblox; HYAS's differentiation is depth of adversary-infrastructure intelligence rather than a fundamentally new technical approach.

Independently tested by AV-TEST with concrete, published block-rate and false-positive figures, plus a separate comparative industry evaluation showing it outperformed competing protective DNS services, genuine third-party validation rather than just vendor claims.

DNS remains a foundational, hard-to-evade control point for blocking malware command-and-control and phishing, and adversary-infrastructure attribution is increasingly valuable as threat actors reuse infrastructure, though DNS security itself is a mature, well-served category.
