What Levelrail adds around it:
- Automatic HTTPS and an ingress shield in front of every domain.
- Deploys are gated on the health check before traffic switches.
- One-step rollback to the previous revision.
- Exposure report shows what is reachable from outside.
- Host firewall rules managed for published ports.
