Network Access Control (NAC)
A control layer that recognizes every user and device connecting to your network and gives only authorized, secure ones as much access as they need.
About This Solution
Today it is not only company computers that connect to the corporate network: guest phones, personal devices, printers, IP cameras and an ever-growing number of IoT devices share the same network. Network Access Control (NAC) evaluates every connecting device by who it is, what it is and how secure it is, and applies the same policy across wired, wireless and VPN connections.
A NAC project is more than installing a product. Building the device inventory, integrating with the identity infrastructure (Active Directory, certificates, MDM), designing policies and moving step by step from monitoring to enforcement without disrupting users all take experience. NAC is one of Novus BT's strongest fields; our projects are run end to end by engineers with deep field experience in this technology.
Risks You Face Without This Solution
When nobody knows which users and devices are on the network, an unauthorized device can reach the internal network unnoticed.
A device with missing updates or disabled antivirus puts the whole network at risk the moment it connects.
Guest and personal devices sharing a network segment with corporate systems make an attacker's lateral movement easier.
IoT devices such as printers and cameras often cannot run security software and stay invisible.
What We Offer
802.1X-based authentication for wired, wireless and VPN access
Automatic discovery and profiling of every connecting device (IoT included)
Posture checks: updates, antivirus and disk encryption
Role-based access and network segmentation with dynamic VLANs / ACLs
Separate, logged access flows for guest and BYOD access
Automatic quarantine of non-compliant devices; firewall, EDR and SIEM integration
Who Is It For?
Ideal for organizations with many users, guests and IoT devices on their network that must answer "who is on our network?" with records for KVKK, ISO 27001 or industry audits.
After deployment, we sustain the value this solution delivers through regular health checks, performance optimization, and 24/7 managed service support whenever needed.
