Allowlist-Based Policy
Only devices explicitly approved are permitted to communicate. Everything unknown — new contractors, rogue devices, infected endpoints — is blocked by default. No exceptions unless explicitly configured.
Default-Deny Network Enforcement
Lock the Network Down. Instantly.
Network Lock enforces allowlist-based access policies across your entire network — blocking every unauthorized device, connection, and protocol by default. No complex NAC infrastructure. No 802.1X dependencies. Works on every device, including IoT, OT, and legacy systems.
The Problem
Traditional NAC Fails Modern Networks
Traditional Network Access Control (NAC) was built for a world of managed laptops, RADIUS servers, and 802.1X-capable infrastructure. That world no longer exists in most environments.
Today's networks include IP cameras, HVAC controllers, infusion pumps, industrial PLCs, VoIP phones, and thousands of other devices that cannot run agents, do not support 802.1X, and were never designed with network authentication in mind. Traditional NAC cannot govern them.
Meanwhile, attackers actively scan for unmanaged devices as entry points. A single IP camera on the wrong VLAN with default credentials can provide a foothold into your entire network. Network Lock solves this with a fundamentally different approach: instead of trying to authenticate every device, it simply permits only what is known and blocks everything else.
- IoT and OT devices cannot run agents or participate in 802.1X
- Legacy devices have no authentication mechanism
- Unknown devices appear on networks constantly — shadow IT, contractors, guest hardware
- Static ACLs and firewall rules cannot keep pace with dynamic network change
- Traditional NAC deployments can take months and cost hundreds of thousands
How It Works
Inventory. Baseline. Lock. Monitor.
-
Inventory Your Network
IoT Secure automatically discovers every device on a network segment — including devices that don't appear in your CMDB, endpoint agents, or vulnerability scanners. Get a complete picture before making any enforcement decisions.
-
Build Your Allowlist
Review discovered devices and approve what belongs. IoT Secure builds a verified allowlist of known-good devices, MAC addresses, and approved communication patterns. No pre-existing inventory required.
-
Enable Audit Mode
Start with zero disruption. Audit Mode alerts your team whenever a new or unapproved device connects — without blocking anything. Use this phase to validate your allowlist before enforcement.
-
Enable Lock Mode
When you're ready, enable Block Mode. Any device not on the verified allowlist is automatically blocked from the network — in real time, without manual intervention, without firewall rule changes.
-
Monitor & Adapt
As your network changes, Network Lock adapts. New approved devices are added to the allowlist. Anomalies trigger alerts. The enforcement posture stays current as your environment evolves.
Key Capabilities
Enforcement Without Complexity
One-Click Lock
Lock an entire network segment with a single action. IoT Secure automatically blocks unauthorized devices the moment you enable enforcement — no ACL changes, no switch configuration required.
Smart Allowlist Learning
Start with an accurate device baseline through passive network observation. Network Lock learns what's connected, how devices communicate, and which connections are normal — before any enforcement is applied.
Zero-Day Protection
Allowlist-based enforcement blocks zero-day threats by default. Even if a device exploits an unknown vulnerability, lateral movement is blocked because the resulting traffic pattern isn't in the approved allowlist.
Where Network Lock Applies
Critical Segments. Consistent Protection.
Camera & Physical Security Networks
Lock down IP camera subnets to prevent cameras from communicating with IT systems, cloud storage, or unexpected destinations. Block unauthorized recording software and credential scanners.
OT & Industrial Networks
Protect PLCs, HMIs, SCADA systems, and industrial controllers from unauthorized access. Enforce strict communication allowlists that prevent IT-OT crossover threats.
Guest & Contractor Networks
Ensure guest and contractor devices cannot access internal systems. Lock segments so that only approved, credentialed devices can reach protected resources.
Clinical & Medical Device Networks
Protect infusion pumps, imaging systems, and patient monitors from lateral threats. Enforce network policies without disrupting clinical workflows or requiring device agents.
One-Click Enforcement
From Discovery to Protected in Minutes
The fastest path from open to locked.
Most organizations spend months configuring NAC systems before achieving any enforcement. IoT Secure flips this model: discover your network, review your devices, and enable lock mode — all in a single session.
Start with your most critical segment. Camera network. Plant floor. Clinical devices. Get that segment under control first, validate the results, then expand. Network Lock scales from a single subnet to enterprise-wide enforcement on your timeline.
Lock your network. Stop the drift.
Deploy in minutes. No agents, no RADIUS, no 802.1X required.
