The zero trust security architecture was created in 2010 by John Kindervag at Forrester Research Inc. It is based on the concept that organizations should not trust anything that is inside or outside its security perimeters, instead of taking the time to verify everything that is trying to gain access to its system before granting it. The zero trust model is growing in use because, despite the fact that organizations are spending more and more on cybersecurity, cybercrime continues to cost businesses millions and billions of dollars. Data breaches are also increasing in scope.

With the traditional security mindset that everything inside an organization’s perimeters doesn’t pose a threat and therefore can be trusted, hackers have been able to move through internal systems without any resistance once they managed to gain access.
