1 The Challenge
Traditional perimeter or "castle and moat" security tools have faced unprecedented challenges in adapting to the demands of rapidly changing digital environments. The evolving threat landscape is exemplified by the persistent threat of cyberattacks, driven by cybercriminals' exploration of new tools and techniques. As a result, Zero Trust has emerged as a key concept for modern cybersecurity.
The concept of Zero Trust is based on the assumption that any network is always hostile, and thus, any IT system, application, or user is constantly exposed to potential external and internal threats. This Zero Trust philosophy has become increasingly relevant as organizations grapple with the proliferation of remote work, cloud adoption, and the growing sophistication of cyber threats. Within Zero Trust, the concept of ZTNA (Zero Trust Network Access) plays a central role.
1.1 Perimeter Security
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. But even more so, traditional remote access solutions like virtual private networks (VPN) can no longer ensure the scalability and performance needed for the increasingly mobile and remote workforce.
