Hardware Firewalls

       Hardware Firewalls are security devices that represent a separate piece of hardware placed between an internal and external network.

Software Firewalls

A software firewall is installed on the host device. Since it is attached to a specific device.It has to utilize its resources to work. Therefore, it is inevitable for it to use up some of the system's RAM and CPU.

Cloud Firewalls

A Cloud firewall or firewall-as-a-service (Faas) is a cloud solution for network protection. Like other cloud solutions, it is maintained and run on the internet by third party vendors.

Proxy Firewalls

It serves as an intermediate device between internal and external systems communicating over the internet. It protects a network by forwarding requests from the original client and masking it as its own.

Circuit-Level Firewalls

Circuit-Level gateways are a type of firewall that work at the session layer of the OSI model, observing TCP (Transmission Control Protocol) connections and sessions.

Stateful Inspection Firewalls

Circuit-Level gateways are a type of firewall that work at the session layer of the OSI model, observing TCP (Transmission Control Protocol) connections and sessions.

Packet-Filtering Firewalls

Packet-Filtering Firewalls serves as an inline security checkpoint attached to a router or switch. As the name suggests, it monitors network traffic by filtering incoming packets according to the information they carry.

Next-Generation Firewalls

The next-Generation firewall is a security device that combines a number of functions of other firewalls. It incorporates pocket, stateful, and deep packet inspection.
