TLS certificates for internal services done right
This technical post discusses the implementation of TLS certificates for internal network services using a split-horizon DNS strategy. The author argues that using public CAs with WAF-protected internal services is more efficient than managing self-signed certificates across multiple clients.
Why it matters
Efficient internal network security is critical for IT infrastructure management, particularly for organizations balancing remote access and internal service security.

Some of those services are external, others internal. In order to reach the internal ones you need to be connected to the VPN.
