Poor security culture accounts for 3 in 4 breaches

Let's fix that!

CLTRe was established in 2015 to accurately answer how do you measure security culture?

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.

Security Culture Defined

"the ideas, customs and social behaviours that your organisation, and its subgroups, have, use and act upon to create a state of being free from threat and danger"

Kai Roer, Build a Security Culture, 2015

What we do

Security culture is an effective mechanism to influence employee behaviour and thereby reduce risk. We help organisations measure and manage their security culture by providing an efficient platform to assess and build their security culture or awareness training programs. Dissatisfied with the lack of useful metrics that awareness programs typically provide, organisations come to us from around the world for services that include:

  • security culture assessments,
  • action items tailored to their needs,
  • external and internal benchmarking used to meet compliance requirements,
  • detailed reports and insights that provide clear strategical direction for managing security culture

Customers include both private and public organisations, such as large banks, multinational retailers and governmental organisations. CLTRe bring insights on human behaviour from a security perspective to influential industry and government bodies, researchers and security practitioners worldwide. We are passionate about helping organisations understand and make sustainable improvements to their security culture long-term.
