**Encryption in transit** refers to protecting data while it moves from one place to another.

There are many options available for encrypting data as it moves over a network. The most common are <Gloss term="MACsec" anchor="macsec" />, <Gloss term="IPsec" anchor="ipsec" />, and host-level encryption. Each of these approaches has its advantages and disadvantages, and each operates at a different level of the network stack.

Using the [OSI Model](https://en.wikipedia.org/wiki/OSI_model), MACsec operates at <Gloss term="Layer 2" anchor="layer2" />, IPsec operates at <Gloss term="Layer 3" anchor="layer3" />, and host level, including TLS and SSH, typically operates at Layers 4-7 within the clients and servers rather than at the network level.

Megaport works with customers using various combinations of all of these protocols, along with many others.
