KnowBe4 Security Awareness Training

Who We Are

At KnowBe4, we’re happy to go against the grain. We don’t turn out bloatware year after year, and we work with far more than just the bottom line in mind.

We’re a team of free-thinking techies who look at IT security issues a little differently. Where other IT security companies may value profits, we value security — helping organizations reinforce their human firewall and build a stronger security culture.

Our Rules

  • 1 Do it right the first time.
  • 2 Do it fast.
  • 3 Have fun while you do it.

We work like that because we think it’s the only way to go. We believe that only with community can you effectively secure your domains. We believe that as IT pros, we need to hang together because if we don’t, we will fall alone.

We support and stand behind the Universal Declaration of Human Rights, which states that equal and inalienable rights of all members of the human family are the foundation of freedom, justice and peace in the world. All human beings should be treated with decency, kindness and respect.

We’re not just a different kind of security company. We’re a security company that, together with you, makes a difference.

Customers of all sizes can get the KnowBe4 platform deployed into production twice as fast as our competitors. Our Customer Success team gets you going in no time, without the need for consulting hours.
