Cloud, security and software built around real infrastructure.
Cloud and cybersecurity services designed around the physical infrastructure 21CTL operates, with software for the business on top.

Security boundaries from the network to the application.
Cloud, cybersecurity and software are designed around the physical layer 21CTL operates, so the platform and the facility are planned together rather than stitched together later.
