The cloud and mobility are empowering digital transformation – all to make business moreagile and competitive. At the same time, users are increasingly remote, working on any device
in any location. Plant operations and OT system owners need a capability to execute outcomeswith a workforce now located anywhere.
Predictive maintenance and remote diagnostics that improve plant uptime requires secure
remote connectivity. VPN-based solutions connecting employees and third-parties to OT
environments introduce significant security risk and complexity. Unplanned downtime fromcyber security incidents or network outages can cause serious harm to plants and personnel,
and result in revenue loss or reputational impact. As a result, security and resiliency to provide
maximum uptime to OT and ICS environments is key.
