How SGBox and CGNAT solve the IPv4 shortage problem.

News | 15.10.2025

With public IPv4 addresses nearly exhausted, companies and internet service providers face the need to find effective and secure ways to expand their networks. One of the key technological solutions to this problem is Carrier-Grade Network Address Translation (CGNAT).

The IPv4 exhaustion problem: a new challenge for business

The shortage of IPv4 addresses is not just a technical limitation. It directly affects a business's ability to scale, connect new users, and launch services. Purchasing the remaining IPv4 blocks on the open market involves huge costs, making this option unaffordable for many organizations. Ignoring the problem leads to network infrastructure stagnation and growth restrictions.

What is CGNAT and how does it solve this problem?

CGNAT (Carrier-Grade NAT) is a technology that allows multiple users within a single network to share one public IPv4 address. Unlike standard NAT used in home routers, CGNAT is designed to operate in large, carrier-grade networks. It efficiently translates private IP addresses from the internal network to a single public one, optimizing the use of address space.

Benefits of SGBox with an integrated CGNAT module

The SecureGate SGBox cybersecurity platform offers a built-in CGNAT module that transforms the standard solution for address shortages into a powerful tool for network management and protection. It's not just address translation; it's a comprehensive approach to network infrastructure.

Key features:

  • Cost savings: Eliminates the need to purchase expensive IPv4 address blocks, allowing the budget to be allocated to developing key services.
  • Enhanced security: By its nature, CGNAT hides the internal network structure from the outside world, acting as an additional security barrier. SGBox enhances this function with its SIEM and SOAR capabilities.
  • Centralized management: The SGBox platform provides a single interface for managing IP addresses, monitoring sessions, and analyzing traffic, which significantly simplifies network administration.
  • Compliance: SGBox maintains detailed translation logs, making it possible to accurately identify a user by their internal IP address and port at any given time. This is crucial for meeting regulatory requirements and investigating incidents.

SGBox turns the necessity of implementing CGNAT into an opportunity to enhance control and security over your network infrastructure.
