Firewalling

Your business can count on a secure, available and efficient environment. The firewall forms a crucial link in this context. Combell provides firewall solutions based on different products from several suppliers.

Load balancing

By using load balancing technology, Combell distributes the workload of your servers optimally across your server farm. This way, we make sure that your infrastructure is as ready as possible to support your business.

There are different methods: a layer 3 load balancer distributes the workload of the servers at the level of the network, a layer 7 load balancer does that at the level of the application layer, combined with SSL or not.

Intrusion Prevention System & Intrusion Detection System

Combell uses several techniques and technologies to detect intrusions on the network and react - automatically or not - as adequately as possible.

Intrusion detection is performed on all core components of the infrastructure and, if desired, can also be performed on the customer's dedicated firewalls.

Routing

Combell is in charge of all the network and routing management. Thanks to our independence from external transit providers, we can provide a faster and more flexible solution to your network needs.

Combell acts as an independent player towards transit providers. Today, Combell uses the networks of Colt, Tiscali, Interroute, Level 3 and KPN (among others). From InterXion, if desired, Combell can provide you with an even greater variety of transit providers.

The networks of over twenty providers are available from InterXion. That gives Combell the flexibility to let you work with your preferred provider. Since we invest and manage ourselves, you always benefit from superior network services: more efficiency and less downtime.

VPN tunnelling

A VPN is an encrypted tunnel over the Internet that connects private networks together. From one LAN (e.g. the company network), there is a connection to another LAN (e.g. the data centre).

In addition to such a fixed LAN-to-LAN connection through a secured Internet connection, it is also possible to use VPN tunnels for temporary point-to-point connections. That sort of VPN tunnelling is popular among companies that want to give their employees secure remote access to the company network or to the data and the applications in the data centre.

Caching

Through caching or temporary storage of often-used data, Combell speeds up the access to these data. The technique of caching consists in the web service storing images, text fragments and other elements of a website on the user's device.

The next time the web service needs one of those elements, it retrieves it from the device's memory, not from the host's. To make this possible, Combell uses Varnish, a solution based on the principle of the reverse proxy server. The benefit of Varnish is that the solution was also specifically developed as a reverse proxy. That provides very efficient caching. This way, Varnish is definitely more efficient than the solution developed by Squid, which is originally a proxy server that was later converted so it could be used as a reverse proxy.
