Network Access Control (NAC)
Overview of Network Access Control (NAC)
Network Access Control (NAC) is a critical security solution that helps organizations manage and secure access to their networks. As the number of mobile devices, Internet of Things (IoT) devices, and remote connections continues to grow, NAC solutions provide the necessary controls to ensure that only authorized and compliant devices can access your network resources. By enforcing security policies, NAC helps safeguard your organization against unauthorized access, malware, and other cybersecurity threats.
Why NAC is Important
In today's rapidly evolving digital landscape, organizations must contend with a diverse array of devices and users accessing their networks. NAC solutions are essential as they provide visibility, control, and compliance capabilities, enabling organizations to:
NAC systems can deny access to noncompliant devices, quarantine them, or limit their access, preventing insecure devices from compromising the network.
By evaluating compliance based on device type, user role, and security status, NAC helps organizations maintain a robust security infrastructure.
NAC solutions offer customizable portals for managing guest access, including registration, authentication, and sponsorship, ensuring guests can connec
NAC can automatically enforce security policies to block, isolate, or remediate compromised devices without manual intervention, streamlining incident response.
Core Capabilities of NAC Solutions
- Policy Lifecycle Management: NAC enforces security policies consistently across all operating scenarios, reducing the need for additional products or modules.
- Device Profiling and Visibility: NAC identifies and profiles devices and users before they access the network, preventing malicious activity.
- Guest Network Access: NAC allows for secure and managed access for guests, contractors, and partners, ensuring they have restricted access to network resources.
- Security Posture Evaluation: NAC checks devices against security policies, ensuring that only compliant devices can connect to the network.
- Integration with Other Security Tools: NAC solutions integrate with other security and network systems through APIs, enhancing the overall security ecosystem.
- Automated Incident Response: NAC responds to security threats by automatically enforcing policies that isolate or repair noncompliant devices.
