Industry first: NAC-integrated private APN security

A private APN trusts the SIM. We verify the device behind it.

APNZone pairs every SIM with its device, validates posture and location, and quarantines a moved SIM before it reaches your systems, on 4G and 5G, through the carriers you already use.

Every connection is checked for IMSI, IMEI, MAC and location. A SIM moved to an unknown device is quarantined.

  • 350K+ cellular field endpoints at a national law-enforcement agency
  • 4G · 5G multi-carrier through standard RADIUS; no carrier lock-in
  • Live policy changes on active sessions, without restarting the SIM or device

How APNZone verifies a SIM before it connects

Five checks on every connection, through the telecom core you already run.

  1. Telecom Core Authentication

    Private APN authentication requests flow through telecom core infrastructure using RADIUS validation.

  2. Identity & SIM Binding

    IMSI and IMEI pairing validates hardware integrity before granting access.

  3. NAC Policy Engine

    Device posture, risk signals and user identity are evaluated in real time.

  4. Dynamic Authorization Control

    Change-of-Authorization enables live segmentation, quarantine and policy injection without disconnecting the device.

  5. Firewall & Data Center Enforcement

    Access is restricted to defined systems only, enforcing micro-segmentation across cellular networks.

One console for every SIM, port and session.

Cellular, wired, wireless and guest access under one policy engine. See it, decide in real time, and ask SAMI when you need an answer fast.

S3M consolidates the controls scattered across your access stack — wired, wireless, mobile and guest — under a single policy and visibility layer.

350K+ endpoints

National Law Enforcement Agency

Our responsibility is national public safety. That means hundreds of thousands of devices operating far beyond the walls of any building — vehicles, mobile data terminals, handheld units, and field equipment spread across an entire country, connecting over cellular networks we do not own. Traditional network security assumes a perimeter you can defend. We do not have one perimeter; we have 350,000 of them, and every single one is mission-critical. A security failure for us is not measured in money. It is measured in public safety. APNZone is the first platform we have seen that treats cellular connectivity as part of the Zero Trust architecture rather than an exception to it. Every field device connects through a private APN — it never touches the public internet, and it is effectively invisible to anyone outside our network. SIM-based identity is fused with network access control, so a device is authenticated and its policy is enforced before it can reach any operational system. If a device is lost, stolen, or behaves abnormally, it is isolated centrally and instantly — across the entire country, from one console. We have run this at a scale of more than 350,000 endpoints. At that scale, most products break, and most vendors disappear. APNZone did neither. For an organization where connectivity is operational capability, S3M turned our largest attack surface into our most controlled asset.

  • Marmia Foods

    People are sometimes surprised when a food distribution company talks about network security, but our business runs on uptime. Our facility operates around the clock: handheld scanners, label printers, cold-storage monitoring, and the systems behind our online ordering platform all depend on the same infrastructure. If that network goes down — or worse, gets compromised — trucks don’t leave, cold-chain visibility goes dark, and customers across more than sixteen states don’t receive their orders. For us, the network is as mission-critical as the warehouse floor itself. ConnGuard gave us something we had never had before: a live picture of every device connected anywhere in our operation, with automatic segmentation that keeps warehouse and IoT equipment completely separate from our business and e-commerce systems. A scanner can reach the warehouse system and nothing else. EndGuard ensures that every office laptop and every sales rep’s device on the road meets our security baseline before it connects — no exceptions. And SpotGate lets visiting vendors, drivers, and contractors get online at our facility without ever touching our operational network. We are not a ten-thousand-person enterprise, but the systems we protect are critical to everyone who depends on us. S3M gave us enterprise-grade Zero Trust without enterprise-grade complexity.

  • Grape Law Firm PLLC

    As a law firm, the confidentiality of our clients’ information isn’t a feature of our service — it is the foundation of our practice. Our attorneys handle immigration cases involving passports, financial records, and government filings every single day, and because we build our own technology in-house, our network carries both privileged case data and an active development environment. There is no version of our business where a compromised network is an acceptable risk. ConnGuard changed how we think about access from day one. Every laptop, phone, printer, and server on our network is now identified, profiled, and held to policy before it can reach anything — and our case-management environment is segmented away from everything that doesn’t strictly need to touch it. EndGuard verifies that every attorney’s device is encrypted, patched, and running our security stack before it connects to case files, whether they are working from our office or remotely. And with SpotGate, clients visiting our offices get seamless connectivity that is completely isolated from the systems where their own sensitive files live. For a firm whose entire reputation rests on protecting what clients entrust to us, that level of control isn’t a luxury. With S3M, an unknown or non-compliant device simply never gets near privileged data.

  • Egea Food

    Egea Food has produced halal-certified Mediterranean and Middle Eastern proteins since 1983, distributing across the United States, Canada, Mexico, and the Caribbean under USDA and HACCP certification. Behind that is a 24/7 operation — production-line controllers, cold-storage and refrigerated-fleet monitoring, warehouse scanners, and the B2B ordering systems our wholesale customers rely on, all on one network. A disruption there doesn’t just slow IT down; it threatens the cold chain and the shipments restaurants and retailers expect on time. ConnGuard gave us a live inventory of every device in the plant and automatically segmented our production and cold-chain IoT away from business and ERP systems — a sensor or scanner can reach exactly what it needs and nothing more. EndGuard makes sure every office and sales device meets our security baseline before it connects. And with SpotGate, the USDA and HACCP auditors, drivers, and outside vendors who come through our facility get online without ever touching our operational network. For a family business whose name has meant trust for four decades, S3M let us extend that trust to our network — without slowing the line.
