European Cloud Stateful Filtering API Driven Cloud

Instance-Level Network Security with Security Groups.

Thalassa Cloud's Security Groups let you easily control which network traffic is allowed to and from your instances.

Stateful Security Controls

Implement stateful traffic filtering with Security Groups that automatically track connection states. Flexible access control with high performance. Infrastructure in the Netherlands ensures compliance with European security standards.

Granular Access Control

Define precise access rules for your instances, working seamlessly with VPC firewall rules for comprehensive security. Implement complex access policies while maintaining network performance and flexibility.

Why Use 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.

Instance-Level Security

Apply security policies directly to instances, ensuring that only allowed traffic reaches your critical workloads, regardless of the underlying network topology.

Dynamic & Flexible Rules

Easily update Security Group rules via API or console as your environments evolve, supporting rapid DevOps changes and automation without downtime.

GDPR-Compliant & EU Hosted

Security Group infrastructure is hosted in the Netherlands, ensuring your data and access policies remain compliant with European and GDPR data sovereignty standards.

High Performance & Scale

Designed for low-latency traffic filtering and able to protect instances add scale, Security Groups add network security without slowing down your applications.

Simple Management

Manage rules and assignments easily through our web console or API. Integrate with Infrastructure-as-Code tools like Terraform for deployment consistency and automation.

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
