Today, businesses of all sizes need to protect their networks. Network access control (NAC) is key to keeping these networks safe and reliable. NAC helps see who is on the network and controls access by setting rules for devices and users.
In this blog post, we’ll explain what Network Access Control (NAC) is, how it works, and why it’s important. We’ll also look at how NAC is different from firewalls and suggest other security options like VPNs to keep your business network secure.
Key Takeaways
- NAC secures private networks by ensuring only authorized devices and users can connect, enhancing overall network safety.
- NAC is crucial for managing Bring Your Own Device (BYOD) environments, ensuring personal devices meet security standards before accessing network resources.
- Combining NAC with VPNs, like TurisVPN, provides comprehensive network security.
What Is Network Access Control ?
Network Access Control (NAC) is a security method that keeps private networks and sensitive information safe by controlling who can connect. It makes sure only approved and secure devices and users get access.
Firewalls and NAC work well together. Firewalls protect against external threats, while NAC manages internal security. Hence, this integration can provide your business’s network a strong and safe protection against security threats.
Is NAC Everything A Business Needs For A Secure Network?
While Network Access Control (NAC) is crucial for network security, it’s not enough on its own. To fully secure a business network, integrating VPN (Virtual Private Network) technology is essential.
Here’s how NAC and VPN work together to enhance network security:
- Secure Remote Access: When employees use a VPN to connect to the company network from remote locations, NAC ensures their devices meet the organization’s security standards before granting access.
- Enhanced Authentication: NAC adds an extra layer of authentication. Even if VPN credentials are stolen, NAC prevents unauthorized devices from accessing the network.
- Policy Enforcement: NAC can enforce security policies on devices connected via VPN, such as requiring up-to-date antivirus software or the latest system patches.
- Real-Time Monitoring: NAC monitors the network in real-time and can detect and respond to any non-compliant behavior, even on devices connected through a VPN. It can isolate or block devices that pose a threat.
For a comprehensive and user-friendly solution that integrates both technologies, we recommend using TurisVPN along with NAC to enhance your network security strategy.
With TurisVPN, users can safely connect to the network from remote locations, perfect for remote work setups. Combining TurisVPN with NAC provides a powerful security solution by securing connections and controlling who can access the network.

Bottom Line
Network Access Control (NAC) is key for protecting business networks by stopping unauthorized users and devices. NAC identifies and checks devices, sets access rules, and keeps an eye on network activity to enforce security policies. This ensures only safe and approved devices can connect.
However, NAC alone isn’t enough. Firewalls control traffic between networks, while NAC focuses on internal device communication. VPNs add an extra layer of security, especially for remote access, by encrypting data and ensuring secure connections.
For the best security, businesses should integrate both NAC and VPN solutions. This combination provides comprehensive protection, securing both internal and remote connections. We recommend using TurisVPN with NAC for strong and easy-to-use security.
