Network Access Control — no unknown device will enter the network

NAC (Network Access Control) is a technology that verifies every device before it gets network access. 802.1X, MAC auth, posture check, and dynamic segmentation — full control over what's on your network.

What we deploy

NAC deployment scope

From port authentication to identity-based dynamic segmentation — we design and deploy comprehensive network access control.

802.1X authentication

Before network access, every device must authenticate via RADIUS. Machine certificates for corporate computers, user accounts for the rest. Integration with Active Directory and LDAP.

Posture check — device state assessment

Before granting access, the system checks: whether the device has up-to-date antivirus, installed patches, and is encrypted. Devices that don't meet requirements are placed in a quarantine network.

MAC Authentication Bypass

Devices without 802.1X capability (printers, IP phones, IoT) authorized by MAC address. Device profiles and automatic assignment to appropriate VLANs.

Profiling and device visibility

Automatic inventory of all devices on the network — type, manufacturer, operating system. Visibility into what's not in the CMDB. Alerts about unknown devices.

Dynamic segmentation

Based on user or device identity — automatic assignment to the appropriate VLAN and access policy. One port, many segments — without manual configuration.

Reporting and compliance

Access reports: who, when, and from where connected to the network. Evidence for security audits and regulatory requirements (NIS2, ISO 27001, Polish financial supervisor KNF).

Do you know what's connected to your network?

The average company doesn't know about 30–40% of devices connected to its network.

An unknown device on the network is an open door for an attacker. NAC closes that door — every device must identify itself before getting access.

FAQ

NAC access control questions

With a properly planned deployment — no. The typical scenario: first we deploy NAC in monitoring mode (without blocking), gather information about devices and profiles, and only then enable policy enforcement. Users with corporate devices don't notice the change.
Devices without 802.1X support are authorized by MAC address (MAB). Device profiles automatically classify device types and assign them to appropriate network segments. Printers to the print network, cameras to the monitoring network — without manual configuration.
No — NAC integrates with existing switches via RADIUS. We require 802.1X support on switches (supported by nearly all enterprise switches from the last 10 years). No hardware replacement needed.
NAC directly meets the access control requirements of ISO 27001 and network asset management requirements. NIS2 requires measures limiting unauthorized network access — NAC is one of the key tools for meeting these requirements.
