Today’s OT networks need to strike a balance between the convenience of convergence and the ability to maintain observability, operability and controllability (i.e. OT security). There are many points in OT security architecture design where these attributes are likely to be targeted.
Security weaknesses found in the control network and field devices are likely to be around for some time yet. Splice secures the OT network with a new approach to logical isolation, control enhancement and behavioural monitoring. This means that investments already made in vulnerable legacy devices and systems will not expose the entire operation.

The diagram below depicts a typical Splice deployment covering an embedded device environment typically found in Property Management, Retail and Healthcare.
The deployment model below is an example of the architecture design for Sensor Networks and SCADA installations typically found in Critical Infrastructure, Mining and Oil and Gas. Splice is deployed with a highly redundant architecture and runs in mirror mode. The Splice overlay network is available as a contingency and can be moved to in-path mode if the network is under attack
