KnowBe4 Cloud Email Security
By KnowBe4
An API-based cloud email security product built from Egress, the UK data-loss-prevention and email security vendor KnowBe4 acquired in 2024, now sold alongside KnowBe4's training platform so simulated-phishing failures and real inbound threats feed the same per-user human risk score. Positioned as a complement to an organization's existing secure email gateway rather than a full replacement.
