Glacier

Glacier is a bespoke provider of secure devices and encrypted communications solutions for enterprise and government customers. The job it does: replacing internal email with channels and direct messages.

It makes the most sense for every team. Alongside the main category they mention Communication Hardware, Messaging, Mobile Apps and Security. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Glacier is based in Annapolis Junction, Maryland and around since 2015. More on glaciersecurity.com.

Our checklist for this category: search, retention policies, and external guest access. Ask for a trial on your own data, not a canned demo.

If you have worked with Glacier, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
