Modern network security is shifting from traditional perimeter defenses to a model driven by remote access and zero trust principles. As organizations adopt remote work and cloud solutions, legacy VPNs are becoming less effective due to their inherent vulnerabilities and broad access permissions. The zero trust approach, built on the principle of continuous verification, ensures that no user or device is trusted by default. This model limits access based on identity and context, reducing risk exposure. Solutions like zero trust network access provide a more secure and flexible alternative, enabling organizations to protect resources while supporting modern workflows and adapting to evolving security challenges.
