New ways to deploy!

Beacon Application unlocks new deployment scenarios

Beacon devices and Beacon virtual machines have helped our customers to always know if their networks leak. After first deployments our customers also wanted to always know when their computers leak. Now they will!

Computers can leak in many ways. Workstations can be plugged to wrong networks in meeting rooms or someone may miswire the patch panel. VPN can fail and a laptop ends up exposed directly to the Internet. Someone connects to the USB port to charge his phone and accidentally tethers the machine to the Internet. Our customers can now deploy the Beacon to all their workstations and laptops and get alerts when accidents happen.

Moreover, sometimes you can not deploy devices and virtual machines to isolated networks. But it is hard to imagine an environment where you can't deploy applications. Beacon Application allows you to secure your assets also in cloud environments such as Amazon AWS, Google Cloud or Microsoft Azure.

Reference customers:

Erillisverkot - State Security Networks Group Finland
Finnish Air Force
Kuopion Energia
Tampere University
Seinäjoen Energia
Turun Seudun Puhdistamo

"Sometimes even the experts get it wrong! So how can we build and ensure the policies - and the technical enforcement of those written policies keep accidents and slip ups from occurring?"

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, 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! With Beacon, the testing is straightforward.


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 Syslog or Slack.

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 ».

Security Camera Network
Security Camera Networks are usually firewalled, Beacon Device can be used to test isolation.

Device Virtual
Management Network
Isolation in Management networks is usually layered. Beacon Device or Beacon Virtual can be used.

Secure Workstation Network
Secure Workstation Networks are usually strictly firewalled, Beacon Device can be used to validate the isolation.

Layered - Airgapped
Dedicated workstation
Needs and means to isolate dedicated workstations can be strong - use Beacon Application to make sure they stay strong.

Device Virtual APP
Industry Network
The strong layered isolation in Industry Networks can be tested with Beacon Device, Virtual or App.

Firewalled - Layered
Virtual Private Cloud
Beacon Application can be installed in clouds and is used to test isolation in VPCs or individual service deployments.

Deploy every way

There are three ways to deploy Beacon - Device, Virtual and App

Beacon Application

Beacon Application is extremely easy to deploy to existing environments. You can also use management tools like Microsoft System Center or GPO, Puppet, Ansible, etc. Just add Beacon application to your management automation and get full coverage on how well your isolation is working.

Beacon Virtual

Launch the virtual Beacons inside data centers and see if they can call their Home. Download Beacon Virtual Machine in standard OVA -format from Beacon Home and put your VM to right network and you are ready.

Beacon Device

Use the Beacon Devices to test network isolation on premises. Leave them behind, move them around, have them all around. Works with Raspberry Pi*. Download image from Beacon Home, copy it to SD card and you are ready to deploy the Beacon Device to your network.
