A Zero Trust approach to cyber security is a concept that has been around for decades, but thanks to advances in technology and the need to adapt cyber security capabilities to support secure hybrid working models and ways of doing business in the digital era, it has never been more relevant.

As businesses embrace Digital Transformation and become increasingly cloud-native, mobile, and interconnected, the corporate network perimeter is gradually disappearing, exposing users to malware, ransomware, and other cyber threats. Traditional perimeter security tools no longer provide adequate protection from these threats.

Zero Trust architectures have gained popularity as a more secure, yet flexible and future-proof alternative to traditional perimeter-based security. By eliminating the very notion of a trusted system, ZT architectures enforce strict identity verification and least-privilege access policies for every user, device, or application, regardless of where they are located.

Zero Trust Network Access (ZTNA) solutions apply this concept to network-based access to existing applications and other systems. By creating a logical identity- and context-based overlay for existing networks and preventing discovery and access of applications for unauthorized users, ZTNA solutions enforce strict, fine-grained policies, thus eliminating the possibility of implicit trust and unchecked access to sensitive resources.

ZTNA is the key technology that enables modern Zero Trust architectures, together with comprehensive identity management, strong multi-factor authentication, and real-time behavior analytics. End user organizations have a multitude of solutions to choose from that promise to address various usage scenarios from cloud migration, and seamless hybrid and multi-cloud architectures, to modern replacements for VPN.

“ Existing ZTNA solutions might be based on different underlying technologies and focus on different aspects of the Zero Trust methodology, but fundamentally, all of them solve the same problem: enabling secure yet convenient access to business applications and other resources for users regardless of their location, whether in an office, at home or anywhere else.”
