Industrial network security

A security computer for providing secure communication over a network, wherein the security computer includes one or more processors that execute instructions to perform actions, comprising:

• wherein one or more security computers are coupled between one or more of a plurality of computers and the network;
• employing an overlay network to enable the one or more security computers to selectively provide secure communication over the network between the one or more of the plurality of computers;
• and
• in response to one or more policies that configure the overlay network as a mesh network, disabling or enabling segments of the overlay network for secure communication over the network for the one or more of the plurality of computers, wherein a management platform stores the one or more policies in a processor readable non-transitory memory.

A system for providing secure communication over a network, comprising:

• one or more security computers coupled between one or more of a plurality of computers and the network;
• a management platform that performs actions, including:
• providing an overlay network that employs the one or more security computers to selectively provide secure communication over the network between the one or more of the plurality of computers;
• and
• providing one or more policies to configure the overlay network as a mesh network, wherein the one or more policies are stored in a processor readable non-transitory memory, and wherein segments of the overlay network are disabled or enabled to provide secure communication over the network for the one or more of the plurality of computers in response to the one or more policies.

A processor readable non-transitory storage memory that includes instructions for providing secure communication over a network, wherein one or more processors execute instructions that perform actions, comprising:

• providing one or more security computers coupled between one or more of a plurality of computers and the network;
• providing an overlay network that employs the one or more security computers to selectively provide secure communication over the network between the one or more of the plurality of computers;
• and
• providing a management platform that includes one or more policies to configure the overlay network as a mesh network, wherein the one or more policies is stored in a processor readable non-transitory memory, and wherein segments of the overlay network are disabled or enabled to provide secure communication over the network for the one or more of the plurality of computers in response to the one or more policies.
