Because Your Business is None of Their Business

Talk Securely Anytime, Anywhere: Protect your calls and messages with end-to-end encryption

Encrypted calls are crystal clear with HD quality audio.

No outsider can hear what you’re saying; while participants in the call can hear each other perfectly.

Consumer-based products are designed to be easy to use, while compromising on privacy. The consumer’s metadata is “the product”. Consumer-based products are not secure.

Enterprise & Government-ready solutions also need to be easy to use, while requiring security and privacy with high performance, oversight, management and control and include enterprise-grade features.

TrustCall is the only solution designed from the ground up to meet government needs and is hosted and run in an IL 4+ Government Cloud.

Department of Homeland Security Recommends End-to-End (E2E) Encryption

“…cellular phones can be tracked, tapped, and hacked—by adversaries thousands of miles away—through SS7-enabled surveillance.”
– US Congress, Letter to Department of Homeland Security (DHS)

“A number of threats against SS7 have been publicly described, including the ability to…intercept or block SMS text messages, and redirect or eavesdrop on voice conversations.”
– Department of Homeland Security (DHS)

“The front lines of cyber conflict today is on the mobile device and even more specifically it’s all about mobile communications”

Koolspan’s Core Principles

We believe that our freedom rests upon a foundation of another liberty, privacy, without which freedom would crumble.
History has demonstrated that when people believe their conversations are monitored they change how they communicate, hold back and refrain from sharing their thoughts and feelings accurately.
Without privacy, we no longer truly have freedom of speech, freedom of religion, a free press or many other sacred liberties.

Stay ahead of pervasive threats to mobile communications; including voice, messaging, and data.
