COSGrid Zero Trust Network Access Control (ZT-NAC) is an identity-first, agent-based network access control solution that replaces legacy NAC with a continuous "never trust, always verify" security model — designed for hybrid workforces, BYOD environments, and distributed enterprise infrastructure. Built on the NIST 800-207 Zero Trust Architecture framework, ZT-NAC moves beyond location-based trust to validate every user and device before granting access — and keeps validating throughout the session. Unlike traditional NAC that relies on hardware appliances, VLAN segmentation, and 802.1X infrastructure, COSGrid ZT-NAC is cloud-managed, infrastructure-light, and deployable in under 15 minutes per site without changes to existing networks. The solution performs real-time device posture assessments — checking patch levels, antivirus status, encryption compliance, and application control — and enforces least-privilege access policies based on user identity, device health, location, and time. MFA and SSO integration ensure strong authentication at every access point, while endpoint-level micro-segmentation prevents lateral movement even after a breach. A single management console provides unified visibility across all endpoints, users, and locations, with comprehensive audit logging to support compliance requirements across industries including financial services, healthcare, and manufacturing. Key capabilities include: Continuous identity and device posture verification Agent-based enforcement — no VLAN changes or hardware appliances required MFA and SSO/IdP integration Real-time posture checks (patch, AV, encryption, app control) Endpoint micro-segmentation to contain lateral movement Cloud-managed with 15-minute zero-touch deployment Unified visibility console with full audit trails * * * Seller [COSGrid Networks](https://www.g2.com/sellers/cosgrid-networks) Discussions [ZT-NAC Community](https://www.g2.com/products/zt-nac/discuss) Overview by Murugavel Muthu (Founder & CEO, COSGrid Networks | Helping CIOs & CISOs Simplify SASE, ZTNA, WAAP & NDR | Predictive Security Through Unified NetSecOps) Show More ## Top-Rated Alternatives [ ![Cisco Duo](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Cisco Duo") Cisco Duo 4.5/5(520) ](https://www.g2.com/products/cisco-duo/reviews) [ ![ThreatLocker Zero Trust Platform](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "ThreatLocker Zero Trust Platform") ThreatLocker Zero Trust Platform 4.8/5(514) ](https://www.g2.com/products/threatlocker-zero-trust-platform/reviews) [ ![Zscaler Internet Access](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Zscaler Internet Access") Zscaler Internet Access 4.4/5(312) ](https://www.g2.com/products/zscaler-internet-access/reviews) [ View All Alternatives ](https://www.g2.com/products/zt-nac/competitors/alternatives) ![Vinay M.](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Vinay M.") VM Vinay M. Technical Lead Small-Business (50 or fewer emp.) 7/24/2026 "Fast, Appliance-Free NAC with Continuous Posture Checks for Hybrid/BYOD" 5/5 What do you like best about ZT-NAC? ZT-NAC let us move away from legacyNAC without ripping out existing network infrastructure deployment was fast and didn't require hardware appliances. The continuous device posture checks (patch level, AV status, encryption) mean access isn't just a one-time gate at login it's re-verified through the session, which fits our hybrid/BYOD environment well. Review collected by and hosted on G2.com. What do you dislike about ZT-NAC? I haven’t used it for very long yet, so I haven’t come across anything I dislike. Review collected by and hosted on G2.com. What problems is ZT-NAC solving and how is that benefiting you? Before ZT-NAC, we relied on legacy NAC ,which meant access was largely location-based and didn't account for device health or ongoing risk. With BYOD and remote employees, that model didn't scale well. ZT-NAC's identity- and posture-based access, plus micro-segmentation to limit lateral movement, has reduced our exposure to compromised or non-compliant devices reaching sensitive systems.
