Beacon — Always know if your networks leak!

Always know if your network leaks

Reference customers

"Companies should invest in monitoring the isolation of their production networks. 81% of the participant organisations’ networks that were intended to be isolated leaked in unexpected ways"

Beacon calls Home

Always know if your network leaks. Designed for customers who depend on network segregation.

Network isolation

You rely on it. You may call it isolation, segregation, segmentation, partition or sandboxing. But do you know it works? Privacy, critical infrastructure protection, payment safety or your sanity may require it.

Cover all the layers

Firewall rules, routing, VPNs, switch VLANs, cabling - it is just impossible to review everything works right everywhere and all the time! With Beacon, the testing is straightforward and continuous.


Rather than finding 300 potential issues in one location, test one important security control in 300 locations.

Beacon calls Home and Home alerts User

Put them in your networks and they will alert if your networks leak. Beacons try to connect to their Home over IPv4, IPv6, TCP, UDP, ICMP, DNS, Ethernet Broadcast and IP Payload. If they succeed, Home alerts you via Slack or HTTP-API.

Beacon covers your bases

Beacon checks for problems with firewalled, layered and air gapped isolations. You can use Beacons to cover a wide range of your protection scenarios, see below for examples and get more in depth look into how Beacon can help from our whitepapers ».
