Black Box (IBB)

Data and Voice/Data Models
Support Commercial & Industrial Applications
Up to 2,048-bit Encryption
Automatic Reboot and Monitored

Interoperable Black Box (IBB)

Authorized by M-SIM®, the IBB connects operational, life-safety, and security systems to the back-end of the mobile carrier network. The IBB features automatic reboot through built-in analytics and can be remotely monitored for periodic health checks. The IBB is available in data and voice/data models with up to 2,048-bit encryption.

Secure Private Network

Uses MPLS Switching
Fortified by a Bank-Grade Firewall
Segregated on the Back-End of Mobile Carrier Networks

Secure Private Network

The Secure Private Network leverages the back-end of most mobile carrier networks. The connection uses Multi-Protocol Label Switching (MPLS) and is fortified by a bank-grade firewall. The result is a true, secure private network. Command and operation centers can connect without exposure to the Internet.

Bank-Grade Firewall

Automatic Failover for High Availability (HA)
Updated in Real Time
Segregated on the Back-End of Mobile Carrier Networks

Bank-Grade Firewall

Using Data Quarantine Technology, the Bank-Grade Firewall detects unknown malware, siphons off malicious code, and isolates threats. High-Availability (HA) service is supported by Automatic Failover and the firewall updates in real-time to ensure protection from the latest known threats.

Various Topologies Available

Levels of Security

Secure Utility’s multi-layered cybersecurity wouldn’t be complete without the Authorized Integrator. They provide technical insights for implementing your true private network, maintain the monthly service, and can pass along extended warranties for your equipment. If you currently work with an Integrator, refer them to Secure Utility for training. If you need an Integrator, contact us and we will provide a referral.

SOC Connection

(Off the Public Internet)
Highest Security

Custom connection from your Secure Operations Center (SOC) to the cellular backhaul. A SOC connection would be used for monitoring and remote system management.

SPN Connection

(Off the Public Internet)
Highest Security

Your remote connection is directed to the Secure Private Network (SPN) by the IBB. SPN connections would be used for remote monitoring and remote system management.

VPN Connection

(Requires Internet)
Limited Security

Connecting over a VPN is more secure than the Internet, but less secure than SOC and SPN. The threat surface includes all users and technology on the VPN.


(Public Internet)
Less Security

Connection to the Secure Utility Bank-Grade Firewall is made over the Internet with a fixed IP. This is less secure and recommended for monitoring only, not remote system management.
