More secure than TLS, because messages encrypted with TLS will be decrypted by the relay server, whereas messages encrypted with E4 can only be decrypted by their recipients (end-to-end encryption).
More efficient than TLS, and runs on the most underpowered platforms thanks to its minimal CPU and memory usage, and a negligible per-message overhead.
Teserakt AG was founded in 2018 in Switzerland by noted cryptographer JP Aumasson. Our goal is to establish strong encryption as standard in IoT and machine-to-machine communications, in the same way that it's now an established practice in human-to-human messaging.
We rely on our experience building secure communication software and industrial cryptography systems. Security protocols and algorithms that we designed are now deployed in millions of devices, and some have become international standards.
We have customers in diverse sectors, such as aerospace and law enforcement technology.
Cryptography is our core expertise. We designed algorithms now used in the Linux kernel and Apple devices.
We design secure software. A security product should improve your security posture, not diminish it.
No bells and whistles. We are not ashamed to say that our solution is simple and only supports a handful of parameters.
"Complexity is the enemy of security" is cliché but true.
Be it CPU, memory, or bandwidth, we minimize resources usage thanks to a meticulous choice of algorithms and software components.
Our technology runs on even the most constrained platforms.
