Protect every server and workload with granular, rule-based traffic control. Cantech Cloud Security Groups act as virtual firewalls, giving you precise control over access to your cloud resources.
Our Security Groups provide essential, instance-level protection for your cloud infrastructure. They act as virtual firewalls that filter traffic precisely where your workloads run, giving you greater control, stronger security, and simpler management.:
Define precise rules based on IP, port ranges, and protocols. Open only what is necessary and block everything else.
Once a connection is allowed, return traffic is automatically permitted. No complex rule duplication required.
Attach Security Groups directly to virtual machines, databases, load balancers, and Kubernetes nodes.
Modify rules instantly without restarting servers. Changes apply immediately.
Apply layered protection by assigning multiple groups to a single instance.
Fully integrated with Cantech Cloud networking, compute, and firewall services.
Security Groups for Cloud Environments can be deployed across these key use cases:
Allow HTTP and HTTPS access while blocking all unnecessary ports.
Restrict database access to specific application servers only.
Control traffic between pods, nodes, and clusters.
Secure communication between internal services.
Permit only trusted IPs to access backend APIs.
Limit SSH or RDP access to authorized IP addresses.
Restrict servers from making unauthorized external connections.
Cantech Cloud Security Groups give you complete control over your cloud traffic while keeping your infrastructure secure and scalable.
Define precise inbound and outbound rules by IP, port, and protocol.
Secure individual virtual machines, databases, and workloads.
Automatic response traffic handling for simplified management.
Apply changes instantly without server downtime.
Combine multiple security groups for stronger protection.
Works smoothly with Cantech compute, networking, and firewall services.
Security Groups and Network Firewalls serve different layers of your cloud security architecture. Understanding how they complement each other helps you build a stronger, defense-in-depth strategy.
| Feature | Security Groups | Network Firewall |
|---|---|---|
| Protection Level | Instance or server level | Network or perimeter level |
| Scope | Applied to individual VMs | Protects entire network |
| Traffic Control | Controls inbound/outbound traffic for specific servers | Filters traffic entering or leaving the network |
| Rule Type | Based on IP, port, and protocol | Based on network security policies |
| Configuration | Simple and instance specific | More advanced and network wide |
| Use Case | Secure specific applications or servers | Protect the entire network from threats |
| Security Layer | Internal security layer | External network defense |
Expose only required services and eliminate unnecessary open ports.
Meet internal security standards and regulatory requirements with strict access control.
Control access policies centrally through the Cantech Cloud Console.
As you deploy more servers, apply consistent security rules instantly.
