Network Access Control (NAC) and Secure Access
Know who and what connects to your network, and isolate non-compliant devices automatically.
Network access control (NAC) identifies every user and device at the moment it connects to your wired or wireless network, verifies its identity, checks its security posture and decides which resources it may reach. It ends the old assumption that anything plugged into a wall port is trusted.
Who needs NAC?
Multi-floor and multi-branch offices, factories, clinics, schools, hotels and any company with heavy visitor traffic, bring-your-own-device policies or a growing number of printers, cameras and other IoT devices. Organisations preparing for ISO/IEC 27001 or handling personal data under KVKK and GDPR also benefit from the access records NAC produces.
What we deliver
- Device discovery and profiling to build a real inventory of what is on the network.
- 802.1X authentication with a RADIUS back end, preferring certificate-based EAP-TLS for corporate devices and MAC authentication for devices that cannot run 802.1X.
- Guest and BYOD access through isolated segments, portals and time-limited credentials.
- Posture checks that quarantine devices with missing patches or disabled endpoint protection until they are remediated.
- Dynamic segmentation with VLANs and ACLs, aligned with a wider Zero Trust approach.
How we work
We start with discovery, design an access policy matrix, run NAC in monitor-only mode so nothing is blocked, then enforce it gradually, starting with guest and IoT networks. Racurity delivers the infrastructure of expert solution partners under one contract and one point of contact, and can forward NAC events to SIEM and SOC monitoring. Network, identity and endpoint security are handled by the same team at Pedante Bilişim.
Frequently asked questions
Will NAC disrupt daily work?
No, if it is rolled out properly. We begin in monitor-only mode and move to enforcement gradually, pilot group first.
Can devices without 802.1X support be managed?
Yes. Printers, cameras and similar devices are profiled, admitted with MAC authentication and placed in restricted segments.
