Datacenter Firewall

Securing datacentre access with a virtual firewall

Virtual OPNsense firewall for your applications

Your Virtual Servers, Email & Calendar, as well as Identity and Access Management in the Swiss Business Cloud, deserve the highest level of protection. The OPEN CIRCLE Datacenter Firewall reliably helps protect your systems and data against unauthorised access and malware.

We rely on OPNsense, a powerful, open-source firewall and routing platform that can be flexibly adapted to your needs. Depending on your requirements, we operate your firewall as a shared or dedicated service, equipped with the necessary CPU, RAM and storage. For maximum reliability, we offer a high-availability option: two firewalls operate in rotation, ensuring your systems remain accessible even during maintenance.

Features

Here’s what you can expect

OPNsense

We use OPNsense as a powerful, flexible and open-source firewall and routing platform for our virtualised data centre firewalls.

Shared or dedicated

Depending on your requirements, we can provide you with either a shared or a dedicated data centre firewall.

High Availability

Would you like to be able to keep working during maintenance windows? No problem. With ‘High Availability’, you get two virtual data centre firewalls. While we maintain one, the other seamlessly takes over.

Resources on demand

The resources (CPU, RAM and storage) of your data centre firewall can be easily scaled to meet your actual needs.

Tools & Technologies

Reliable, transparent, independent – our technology stack

The OPEN CIRCLE Datacenter Firewall is built on robust tools – either open-source or fully self-hosted. This allows us to retain full control over security, management and operations.

Enjoy a wide range of benefits

Network-level security

The firewall allows you to restrict access to your data centre resources at the network level. This enables you to block access from known malicious systems or entire regions (geo-blocking).

Secure networking via VPN

Various VPN technologies (e.g. WireGuard, IPsec, OpenVPN) are available to help you establish secure connections between locations and systems.

Regular updates

We monitor the firewall and update the software regularly, so that you are always up to date.

Flexibly expandable

As an open-source firewall platform, OPNsense offers maximum flexibility. If required, we can assist you with the implementation of specific use cases and solutions.

High availability and reliability

If your systems behind the firewall need to remain available with as little downtime as possible, we offer a high-availability setup so that we can update your firewall without any downtime.

Disclaimer: A comprehensive security strategy is always multi-layered and must cover all systems involved. The data centre firewall is an important component (first line of defence), but on its own it does not provide absolute protection against today’s threats from malware, encryption Trojans and other attacks.
