Encrypted Calling
Strong security is the name of the game. With Encrypt Fortress Call, you can count on secure communication provided through:
For your protection, Encrypt Fortress Call registers your incoming phone numbers in trust. Your company can depend upon its privacy being protected by the Republic of Panama's offshore privacy protection and secrecy laws.
To avoid unwanted calls, your outgoing caller ID can keep your number anonymous with the option of setting it to one of your private incoming numbers or Encrypt Fortress Call general voicemail. Every device on the Encrypt Fortress Call system also functions with a unique and private internal encrypted calling 5-digit number.
Encrypt Fortress Call from Encrypt Fortress® always deploys preventive measures to protect our clients against MitM (Man in the Middle attacks). We are dedicated to keeping your encrypted conversation between you and your intended party. Encrypt Fortress Call ensures that no one interferes with the ZRTP encryption negotiation through simple but powerful mechanics (Short Authentication String and Retained Shared Secrets).
With every call, both caller and recipient will see the 4-character SAS displayed on the screen. Each caller can verify the SAS data and match verbally over the secure connection. For example, the caller can read the initial two SAS characters and the receiver reads the last two characters.
A matching SAS confirms that no one interfered with the key negotiation during ZRTP encryption. It is best to do this at the beginning of your conversation. You may then change the SAS status to “verified”. Verification is necessary for Encrypt Fortress Umbra to subsequently secure information in further encrypted connections. A warning message will appear if the SAS key does not match or if Encrypt Fortress Umbra identifies possible MitM.

Encrypt Fortress Umbra is packed with amazing features. You get one-on-one and group video calling, text and picture messaging, screen sharing, free voice calling, and more while all staying completely encrypted with almost no extra effort.
We needed to rethink our digital communications strategy and switch to a secure messaging program. Members of our company were all using different platforms such as Skype, SnapChat, Facebook Chat, WhatsApp, or Google Chat. As part of a campaign to find "Secure and usable crypto," we evaluated 29 messaging products ranging from chat clients, text messaging apps, email applications, and voice and video call tools to find what would work for all our employees to unify them. In the end, it was the features and Ease of use to stay secure in Encrypt Fortress Umbra and messaging that made us switch.
