From advanced inventions to real-world products.
C-K9 is developed by VESNX, a Belgian company focused on advanced cybersecurity and encryption. In less than a decade, our technology has reached over 20 million downloads. Our goal is simple: to become the cybersecurity layer people can rely on, everywhere.
Behind C-K9 is a multidisciplinary international team of cybersecurity experts, focused on building resilient, future-proof protection for digital environments.
C-K9 is not just a logo.
C-K9 is a digital watchdog. Inspired by the Belgian Malinois. Alert every nanosecond. Built to protect digital identity, private data, communication, clouds, devices and businesses.
Charlie doesn't sleep, doesn't blink, and never asks for permission to notice. That's the standard we hold every C-K9 product to.
