Instance-Level Network Security with Security Groups.

Thalassa Cloud's Security Groups provide granular control over instance-level network traffic, allowing you to define precise access rules for your cloud resources. Working in conjunction with VPC firewall rules, our security groups enable comprehensive security for your cloud infrastructure.

Stateful Security Controls

Implement stateful traffic filtering with Security Groups that automatically track connection states. Our platform provides flexible access control while maintaining high performance. All infrastructure is located in the Netherlands, ensuring compliance with European security standards.

Granular Access Control

Define precise access rules for your instances, working seamlessly with VPC firewall rules for comprehensive security. Our Security Groups enable you to implement complex access policies while maintaining network performance and flexibility.

Frequently Asked Questions

Security Groups are instance-level network security controls that act as virtual firewalls for your cloud resources. They allow you to control inbound and outbound traffic based on protocols, ports, and source/destination IP addresses. Security Groups are stateful, meaning they automatically track connection states.

Security Groups and VPC Firewall Rules work together to provide layered security:
  • Security Groups control traffic at the instance level
  • VPC Firewall Rules control traffic at the network level (VPC and subnet)
  • This multi-layer approach provides defense-in-depth security

Our Security Groups include:
  • Stateful traffic filtering
  • Protocol and port-based access control
  • Source and destination IP filtering
  • Integration with VPC firewall rules
  • Multiple security groups per instance

You can implement new security group rules instantly through our API or web console. Our platform supports:
  • Immediate rule application
  • API-driven automation
  • Bulk rule updates
