# Security

How Captic protects your devices, your data and your networks.

Security is built into every layer of the Captic platform.

1. [Device & Cloud Security](/docs/overview/good-to-know/security/device-and-cloud-security.md): how the device and the Captic cloud protect your data.
2. [Network Security](/docs/overview/good-to-know/security/security.md): the five connectivity tiers, from open internet to no internet access at all.
3. [Remote Access](/docs/overview/good-to-know/security/remote-access.md): how we support your devices remotely, and how to use your own tool instead.
4. [IT/OT Separation](/docs/overview/good-to-know/security/it-ot-separation.md): how Captic keeps your IT and OT networks apart.
