Legacy NAC is Infrastructure-Heavy
- VLANs and switches required
- Difficult to scale to branches
- Costly hardware & maintenance
Secure Corporate LAN Access
Validates every device at connection. Applies deny-by-default firewall policies
Secure Network Access
through Zero Trust
An agent-based Zero Trust NAC that enforces
access policies at the moment of connection.
What Is COSGrid NAC?
COSGrid’s Zero Trust NAC is a modern, agent-based network access control solution designed to enforce strict access policies the moment a device connects to your LAN without requiring legacy VLAN segmentation or manual switch configurations.
Challenges
LAN Access is Blindly Trusted
- No user identity enforcement
- Devices access LAN instantly
- No posture or compliance check
Remote + Office creates Policy Gaps
- Separate controls for each zone
- Split-tunnel risks at branches
- Inconsistent enforcement experience
Compliance Needs Continuous Proof
- Audit trails often incomplete
- No visibility into LAN users
- Difficult to prove Zero Trust
