Network Access Control (NAC)
Network Access Control (NAC)
What is it?
Network Access Control (NAC) is a security technology that helps organisations protect against unauthorised access, malware, and other security threats, enhancing overall network security and compliance. It does this by regulating and managing the access of devices to a network, ensuring that only authorised and compliant devices can connect. It involves authentication, authorisation, and enforcement policies to safeguard network resources. A modern NAC solution identifies every device across a heterogeneous environment, checking devices for security updates, antivirus software, and adherence to network policies before granting access. It provides organisations with the ability to assess the security posture of each device, activate remediation workflows and implement access controls. It will continuously monitor all the connected devices on the network and automate responses when unusual behaviors or noncompliance is detected.
Why now?
- The average CIO will be responsible for securing more than 3 times the number of endpoints in 2023 compared to 2018 including IoT & OT.
- Effective cyber resilience starts with 100% visibility of all IP connected devices, in real time.
- Digital transformation continues to drive automation of business operations. Improved efficiency, interconnectivity and information sharing is needed to support this, which increases business risk.
- Threat actors can now move more freely across interconnected networks, accessing sensitive information and causing business disruption.
- IT and OT convergence has resulted in new demands on CIOs and CISOs, who are now tasked with protecting the entire business ecosystem. Responsibilities now extend beyond user devices, applications and data, to ensure secure and streamlined business operations.
- Communications between devices and networks are much faster. Transient devices only need milliseconds of unmonitored access to expose an organisation to risk. To take on these challenges, quick access to a real time view, with 100% device visibility, is required.

Real World Scenarios
Asset Management
Gain visibility of hardware and software that you didn’t know you had for an annual software audit.
Endpoint Compliance
Streamline a security audit to determine whether networked devices are running up-to-date security software.
Continuous Monitoring
Create and apply a policy that notifies you of out-of-compliance hosts and confirms that systems are restored to company standards.
Incident Response
Respond to an outbreak such as WannaCry by using an automated policy to quickly locate vulnerable / infected hosts and determine which need action.
Network Segmentation
Assess endpoints and restrict, block or quarantine non-compliant devices. Then tag non-compliant systems and use assets, such as firewalls, to segment.
Management Reporting
On demand reporting of device hygiene, asset inventory and vulnerabilities. Communicate cyber posture effectively with management in response to any incident or latest outbreak.
