    A firewall is a network security system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both.

    A firewall is a network security device that grants or rejects network access to traffic flows between an untrusted zone (e.g., the Internet) and a trusted zone (e.g., a private or corporate network). It can be implemented in both hardware and software, that uses rules to control incoming and outgoing network traffic.

    Hardware Firewalls- It can be purchased as astand alone product but are also typically found in broadband routers, and should be considered an importnat part of your system and network setup.

    Software Firewalls- It has to be installed on your computer (like any software) and you can customize it; allowing you some control over its function and protection features. A software firewall will protect your computer from outside attempts to control or gain access your computer.

    I cant speak on whether or not the firewall offers any seo benefits but I would imagine it would especially if it is caching faster. However Moz has compiled a listing of algorithm updates. I would look at when your rankings started to fall and see if it matches up with the updates and check your backlink profile and do some competitor research to see if anyone is doing anything different.

    A firewall is a network security device that monitors traffic to or from your network. It allows or blocks traffic based on a defined set of security rules.

    A firewall is a network security system, either hardware or software-based, that uses rules to control incoming and outgoing network traffic.

    A firewall acts as a barrier between a trusted network and and an untrusted network. A firewall controls access to the resources of a network through a positive control model. This means that the only traffic allowed onto the network is defined in the firewall policy; all other traffic is denied.

    A firewall program is a system protection device that watches inbound and confident system visitors and chooses whether to allow or block specific visitors based on a detailed set of protection rules.
