| Assumes implicit trust for users and devices within the network perimeter | Never trust, always verify: every access request is explicitly verified, regardless of location or network origin |
| Emphasizes securing the network perimeter using firewalls and intrusion prevention systems | Focuses on securing individual resources by enforcing strict access controls and continuous verification |
| Grants broad access once inside the network, often leading to over-privileged users | Implements the principle of least privilege, granting users only the access necessary for their roles |
| Typically relies on single sign-on or periodic authentication, assuming continued trust post-login | Requires continuous authentication and authorization, often incorporating multi-factor authentication and real-time context evaluation |
| Reactive approach, detecting threats after they have penetrated the network | Proactive monitoring with real-time analytics to detect and respond to threats promptly |
| Challenges in adapting to cloud environments and remote work scenarios due to reliance on a defined perimeter | Designed for scalability, accommodating cloud services, remote workforces, and BYOD policies seamlessly |
Implementation Complexity | Generally simpler to implement in traditional static environments | May require significant changes to infrastructure and policies but offers enhanced security posture |
| Suitable for organizations with centralized resources and minimal remote access requirements | Ideal for modern enterprises with distributed resources, cloud adoption, and a mobile workforce |
