# S3M Security

Source: https://s3msecurity.com/

S3M Security is a US-based cybersecurity company headquartered in Sunny Isles Beach, Florida, providing a hybrid Network Access Control (NAC) platform that unifies Zero Trust, endpoint posture, guest access, and private APN / cellular security under a single policy engine.

S3M replaces up to four separate access-control vendors with one platform: NAC, endpoint, guest and private APN — on-prem, SaaS, or MSSP. Its strongest differentiator is NAC-integrated private APN / cellular Zero Trust security, an industry first that extends identity-based access control to cellular and IoT connections legacy NAC cannot reach.

## 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.

## Key figures

- **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
- **4 → 1** — Replace up to four access control vendors with a single platform.
- **60%↓** — Lower licensing & operational spend vs. Cisco ISE-class deployments.¹
- **Days** — First module live in days, not quarters. Full platform rollout in weeks.
