# Security Groups

> Optidata Security Groups are platform firewalls for Cloud Compute: you define ingress and egress rules by protocol, port and source or destination once, and attach them to instances instead of managing host firewalls by hand.

**Firewall rules once. Fleet-wide.** Security Groups are platform firewalls for Cloud Compute: ingress and egress rules you attach to instances instead of managing host firewalls by hand.

## What you get

- **Ingress & egress:** Allow or deny by protocol, port, and source/destination.
- **Attach to instances:** Apply the same ruleset across the fleet.
- **Wizard-friendly:** Create or select a group while deploying Compute.
- **Pairs with VPC:** Private networking plus firewall policy in one model.

## How it works

1. **Create a group:** Name the ruleset and define allow/deny entries.
2. **Attach to Compute:** Select the group during deployment or attach it to an existing instance.
3. **Update centrally:** Change rules once: instances inherit the policy.
