The Quiet SSL Revolution Powering Internal Apps – 4 Case Studies

Securing internal web applications—whether they’re behind a firewall or only accessible within a company network—can be surprisingly complex. Most public SSL certificate providers don’t support non-public domains, and self-signed certificates often trigger browser warnings and compromise user trust.

That’s where SecureNT Intranet SSL steps in.

In this post, we showcase four real-world case studies of companies across industries that solved their internal security challenges using SecureNT Intranet SSL. From manufacturing firms to software development agencies, each company had one thing in common: they needed a simple, secure, and trusted SSL solution for internal use. Here’s how they did it.
