Secure Network Access through
Zero Trust
Overview
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
Legacy NAC is Infrastructure-Heavy
- VLANs and switches required
- Difficult to scale to branches
- Costly hardware & maintenance
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
Core Features
What Sets ZT-NAC Apart From Others?
Micro-Agent Footprint with OS-Level Enforcement
- Occupies under 2 MB, minimizing endpoint performance impact
- Enforces policies via built-in OS firewalls without overlays.
Continuous Posture Validation Beyond Initial Authentication
- Verifies device posture continuously throughout user sessions.
- Dynamically adjusts access based on real-time compliance status.
Endpoint-Centric Micro-Segmentation
- Segments traffic directly at endpoints,removing VLAN dependencies.
- Prevents lateral movement without complex network reconfiguration.
Unified Agent for LAN and Remote Access
- Single agent secures both on-premises and remote connections.
- Consolidates policy configuration within one unified management interface.
Use Cases
Secure Corporate LAN Access
Validates every device at connection. - Applies deny-by-default firewall policies.
Real-Time Device Compliance Enforcement
- Continuously monitors patch and antivirus.
- Automates remediation for non-compliant devices
Secure BYOD and Contractor Onboarding
- Profiles and segments unmanaged devices.
- Enforces contextual access rules automatically.
Guest Network Isolation Control
- Creates temporary micro-segments for guests.
- Restricts guest-to-corporate network communications.
Rogue Device Infiltration Prevention
- Detects unauthorized devices in real-time
- Quarantines suspicious endpoints automatically in seconds.
Audit & Regulatory Readiness Acceleration
- Generates detailed access audit trails.
- Helps Audit team in being prepared with logs
