GlobalConnect launches NAC to improve control over network access. The new security service helps organizations identify which users and devices connect to their networks and strengthens cybersecurity as the number of connected systems and devices continues to grow.
Today’s corporate networks include far more connected devices than in the past. IoT solutions, remote work, and the use of personal computers and mobile phones for work mean more users and systems must be managed within the same network environment. At the same time, demands for access control, traceability, and documented security have become stricter.
GlobalConnect is now launching the NAC security service (Network Access Control), which gives businesses better visibility and control over which users and devices connect to the network and strengthens organizations’ ability to meet increasing security and regulatory requirements.
A network cannot be secure if you lack an overview of who and what is connected. NAC provides the visibility and control needed to protect critical systems and comply with tighter regulatory demands, says Anna Granö, EVP B2B at GlobalConnect.
Small devices can create major security gaps
Many organizations host critical systems alongside a growing number of connected devices that are not always managed by IT. These can include cameras, sensors, printers, and other Internet of Things (IoT) devices with limited built-in security. If such a device is compromised, it can serve as an entry point for attackers seeking to move deeper into the network.
When devices are automatically trusted as soon as they connect, they may gain broader access than intended. NAC changes that by identifying and classifying every user and device and enforcing precise access policies for each.
Limits damage and prevents lateral movement
With Network Access Control in place, the network becomes a more controlled environment where access is granted based on well-defined rules. Unknown or non-compliant devices can be blocked or placed into segmented areas with restricted access. That containment reduces the impact even if an individual device is compromised.
NAC is not about stopping every single attack, but about ensuring that an intrusion cannot spread across the network. By controlling access, we significantly reduce the risk of lateral movement, which is crucial for limiting the consequences of security incidents, says Søren Gjevert Petersen, Senior Director, Security Services.
Practical support for modern security requirements
The need for Network Access Control is driven by several concurrent developments. The number of connected devices is rising, working practices are changing, and the threat landscape is increasingly dominated by ransomware and attacks that exploit weaknesses inside the network. At the same time, organizations are expected to demonstrate clear control over their digital environments.
For many organizations, the core goal is to reduce the attack surface and achieve real operational control at the network level. NAC is a practical tool for turning security requirements into concrete measures, says Søren Gjevert Petersen.
About NAC (Network Access Control)
NAC is a security service that:
- Provides full visibility of users and devices connected to the network
- Controls access based on identity, device type, and security posture
- Blocks or isolates unknown and non-compliant devices
- Contains the spread of security incidents
- Serves as an important enabler for a Zero Trust network
- Supports requirements for access control and documented security
By combining identification, continuous monitoring, and automated policy enforcement, NAC helps businesses maintain a secure, manageable network environment even as connectivity and device diversity increase. Implementing NAC complements broader security strategies, including endpoint management, network segmentation, and identity-based access controls, and supports compliance efforts by providing documented control over who and what connects to corporate networks.
