Our take
With AI-powered scams and deepfakes on the rise, companies are struggling to keep their teams safe from ultra-realistic phishing attacks.
That's where Adaptive comes in with its next-generation security training platform built to tackle the kind of threats traditional tools can't keep up with. In short, Adaptive helps people spot the fakes before they get fooled. And it does so by using lifelike simulations across email, voice, and SMS to train employees for real world attacks.
It's clearly working too as they've recently raised $55M, backed by OpenAI and Andreessen Horowitz. The company's already trusted by the Dallas Mavericks, First State Bank, BMC and more too. And with threats evolving fast, Adaptive is set to continue helping companies protect their people.
