Conclusion
Zero Trust offers many benefits.
It enables you to protect your organization from internal and external threats, prevent data breaches, and vastly reduce the scope of potential data loss, if an adversary should gain entry into your network.
There is no one-size-fits-all answer to implementing Zero Trust.
Each organization will approach it differently, depending on the make-up of their IT environment and their business requirements. The reality is no one can simply start with a clean slate and keep their organization running at the same time. As the authors at NIST put it: “Moving to a Zero Trust Architecture will likely never start from scratch but will involve a series of upgrades and changes over time.” The extent of those changes, however vast or slight, will depend on your organization.
But with a proven methodology—one that makes use of the security investments you have made, supplementing or replacing those investments with new technology only where necessary—you can implement Zero Trust, even in the most complex environment.
