# Firewall Product Description

A firewall is a system that monitors and filters traffic passing through it based on configured rules. It protects the infrastructure located behind it from network attacks.

Available for order:

* [hardware firewalls](#hardware-firewall);
* [virtual firewalls](#virtual-firewall).

The suitable [firewall type](/firewalls/order/firewall-types.mdx) depends on your infrastructure and intended use cases.

You can also use free firewalls:

* for dedicated servers and Colocation — [basic stateless firewall](/basic-firewall/about/about-basic-firewall.mdx);
* cloud servers — [cloud stateful firewall](/cloud-servers/firewalls/about-firewalls.mdx).

With a single firewall, you can protect servers across different services and pools; to do this, use the [Selectel Global Router](/global-router/about-global-router.mdx).

### Hardware firewall \{#hardware-firewall}

A hardware firewall is a dedicated device for traffic processing.

For [ordering](/firewalls/order/order-hardware-firewall.mdx), the following hardware firewalls are available:

* Selectel is a solution based on a dedicated server with the [pfSense](https://www.pfsense.org/) software package deployed, which acts as a router and firewall;
* Fortinet;
* UserGate;
* Cisco;
* Continent;
* CheckPoint.

For a list of available models and their specifications, see the [Firewall Types](/firewalls/order/firewall-types.mdx#hardware-firewalls) guide.

The hardware firewall rental service includes:

* a rack-mounted firewall;
* firewall connection to the Internet with a public IP address allocated;
* connection to the Selectel local network;
* access to the graphical and console interface for managing and configuring the firewall;
* replacement of failed components and network equipment in case of hardware malfunction;
* technical support for device operation and network connectivity.

Configuration and administration of the firewall are your responsibility. If you need assistance with firewall configuration or administration, [order a managed services plan](/managed-services/about-managed-services.mdx#security-tools-administration).

### Virtual firewall \{#virtual-firewall}

A virtual firewall is software that is deployed in a virtual environment, for example, on a [cloud server](/cloud-servers/about/about-cloud-server.mdx) or in a [VMware-based cloud](/public-cloud/about/about-public-cloud.mdx).

Depending on the required firewall throughput, the configuration of the server where the firewall is deployed must meet the [requirements](/firewalls/order/firewall-types.mdx#configuration-requirements) for the number of vCPUs, RAM, and disk space.

For [ordering](/firewalls/order/order-virtual-firewall.mdx), UserGate Virtual Edition virtual firewalls are available. For a list of available models and their specifications, see the [Firewall Types](/firewalls/order/firewall-types.mdx#virtual-firewalls) guide.

The virtual firewall rental service includes:

* a firewall image with a license activation key;
* [additional modules](/firewalls/order/firewall-types.mdx#additional-modules).
* access to the graphical and console interface for managing and configuring the firewall;
* support for Selectel resources on which the firewall is deployed.

Configuration and administration of the firewall are your responsibility. If you need assistance with firewall configuration or administration, [order a managed services plan](/managed-services/about-managed-services.mdx#security-tools-administration).
