By default `vminsert` and `vmselect` nodes use unencrypted connections to `vmstorage` nodes, since it is assumed that all the cluster components run in a protected environment. [Enterprise version of VictoriaMetrics](https://victoriametrics.com/products/enterprise/) provides optional support for [mTLS connections](https://en.wikipedia.org/wiki/Mutual_authentication#mTLS) between cluster components. Pass `-cluster.tls=true` command-line flag to `vminsert`, `vmselect` and `vmstorage` nodes in order to enable mTLS protection. Additionally, `vminsert`, `vmselect` and `vmstorage` must be configured with mTLS certificates via `-cluster.tlsCertFile`, `-cluster.tlsKeyFile` command-line options. These certificates are mutually verified when `vminsert` and `vmselect` dial `vmstorage`.
Additionally the following optional command-line flags related to mTLS are supported:
The following optional command-line flags related to mTLS are supported:
- `-cluster.tlsCAFile` can be set at `vminsert`, `vmselect` and `vmstorage` for verifying peer certificates issued with custom [certificate authority](https://en.wikipedia.org/wiki/Certificate_authority). By default system-wide certificate authority is used for peer certificate verification.
- `-cluster.tlsCipherSuites` can be set to the list of supported TLS cipher suites at `vmstorage`. See [the list of supported TLS cipher suites](https://pkg.go.dev/crypto/tls#pkg-constants).
