Network Access Control
Control Who & What Gets on Your Network
Always Verified, Always Managed
When all sorts of devices and users are trying to connect — employees, guests, BYOD, IoT, shadow devices — your network is exposed. Key pain points include:
- Unknown or unmanaged devices slipping in
- Weak or inconsistent enforcement of access policies
- Lateral movement, insider threats, rogue endpoints
- Guest / contractor access lacking controls
- Visibility gaps: who is connected, how, and what posture
- Scaling access management across wired, wireless, remote
If NAC is weak or missing, intrusion, data exfiltration, and compliance failure become real risks.
Network Access Challenges
Unseen / Unmanaged Devices
Devices join your network without IT’s knowledge — unmanaged IoT, shadow systems, rogue hardware.
Admission of Non-Compliant Endpoints
Devices may have missing patches, weak AV, misconfigurations — yet still be allowed on the network.
Lateral Movement & Insider Risk
Once inside, malicious users or compromised machines can move across your network to reach critical assets.
Guest / Contractor Access Chaos
Guests, contractors, and partners often need access — but unmanaged guest connectivity is a major risk vector.
Policy Inconsistency Across Domains
Wired, wireless, remote VPN segments, and switches often use disjointed systems — policy drifts, enforcement gaps.
Scale & Complexity of Management
As the network grows, so does the operational burden of rules, exceptions, onboarding, and changes.
Subnetik Solutions
Unseen / Unmanaged Devices
Continuous discovery, fingerprinting, profiling, and integrating with endpoint and inventory systems.
You see every device and can enforce access—or deny—before things go wrong.
Admission of Non-Compliant Endpoints
Enforce posture checks (OS version, security agents, patch level), and block or remediate noncompliant machines.
Only trusted, secure devices gain access — reducing risk.
Lateral Movement & Insider Risk
Micro-segmentation, dynamic isolation, context-aware access—limit lateral spread by role, time, behavior.
Even if one node is compromised, it can’t freely traverse the network.
Guest / Contractor Access Chaos
Self-service portals, sponsored access, limited role-based access, time-bound connectivity, auditing.
Temporary access without sacrificing security or requiring heavy IT effort.
Policy Inconsistency Across Domains
Centralized policy engine / controller, lifecycle policy templates, uniform enforcement across domains.
Policies stay consistent everywhere — reduce misconfiguration, simplify audits.
Scale & Complexity of Management
Automation, policy templates, zero-touch device onboarding, rule cleanup, role-based delegations.
Less manual work, fewer errors, scalable NAC operations.
Why This NAC Approach Works
- Comprehensive Visibility & Control — Every device and user is accounted for, profiled, and controlled.
- Trusted Device Admission — Enforce endpoint health before granting access.
- Zero-Trust Enforcement Inside — Micro-segmentation and conditional access prevent lateral spread.
- Safe Guest / BYOD Handling — Guests, partners, and personal devices can be managed without weakening security.
- Unified Policy & Seamless Enforcement — One policy engine across wired, wireless, remote domains.
- Operational Efficiency at Scale — Automation, templates, onboarding reduce cost and complexity.
NAC is a foundational element of a Zero Trust Architecture — verifying every access, enforcing least privilege, and continuously monitoring post-admission behavior.
