Mutual TLS
The main requirement to make it work is that SSL traffic should be terminated by Tyk itself. If you are using a load balancer, you should configure it to work in TCP mode.
How Tyk Supports mutual TLS
Tyk has support for mutual TLS in the following areas:
mTLS for cloud users:
- Cloud users can secure their upstream services with mTLS but mTLS between the client (caller of the API) and Tyk’s gateway cannot be done for the time being.
- Multi cloud users - since you own and manage the gateways, you can use mTLS for gateway <–> upstream as well as client <–> gateway connections.
Before going into details about each of these areas, let’s describe the basic building blocks used to make it work.
