CLTRe - a KnowBe4 company

CLTRe was established in 2015 to accurately answer, how do you measure security culture?  By pooling the knowledge and experience of its co-founders and a wider team of experts together, CLTRe developed the Security Culture Survey to provide an effective and easy-to-use method to assess the current state of your security culture and track its changes over time.

The Security Culture Survey uses proven social scientific methods and principles to provide reliable, evidence-based results that enable organizations to assess, build and improve their security culture.

What we do

Security culture is an effective mechanism to influence employee behaviour and thereby reduce risk. As the dedicated security awareness, behavior and culture research center of KnowBe4, inc, we explore huge datasets to learn how millions of employees worldwide discover and respond to cyber threats.

By combining data from the Security Culture Survey with behavior data, knowledge tests and training content consumed by millions of employees, CLTRe is diving deep into how organisations best can reduce their risks.
