Haven't tried it myself, but while it seems Gravitational is focused on SSH and Kubernetes use-cases, we've built Twingate to support a wide range of protocols and use-cases across the organization.

We use Kubernetes internally and we use Twingate to securely access internal tools (Like ELK, Grafana, as well as SSH) without having to expose public IPs or worry whether they get hacked or DDoSed. Before Twingate we had to spend a lot of effort to make such tools accessible securely.
