enSilo took a different approach to securing the endpoint. It all began with a simple premise.


How do you protect endpoints despite being infected?

The answer was simple. Protect the endpoint and its corresponding data, out of the box, and in real-time, no matter what. In doing so, it required development of a patented approach to provide post-infection protection. Over time we have developed pre-infection, threat hunting, and incident response capabilities for a comprehensive endpoint solution. Some of our customers have called it an upside-down approach. Others have said we take all the security drama out of the picture. Any way you look at it, it’s a refreshing approach, because enSilo protects endpoint both pre- and post-infection. We worry about malware so you don’t have to.


The enSilo team brings over 100 years of operational experience in cybersecurity from some notable companies.
