How Does Public Cloud Firewalls Work?

by Daniel Smith Cloud Consultant | Content Writer

Public cloud firewalls are a great way to protect your network from the outside world. They can be used for many different purposes, including: 


  • Protecting sensitive data and applications 

  • Preventing unauthorized access to your network 

  • Enforcing security policies 


But how do they work? What is their purpose? And what should you look out for when choosing one? Let’s take a closer look at public cloud firewall technology. 


What Is a Public Cloud Firewall? 


A public cloud firewall is a software-based solution that protects an organization’s network by filtering traffic between its internal resources and external networks. 


It does this by inspecting all inbound and outbound communications on the network. This means it will monitor everything going through the router or switch, such as email messages, web requests, file transfers, etc. 


A public cloud firewall works by analyzing packets of information sent over the internet. When a packet arrives, it is inspected to determine if it meets certain criteria. 


If it does, then the packet is allowed to pass through; otherwise, it is blocked. The criteria may include things like IP addresses, ports, protocols, MAC addresses, and more. 


How Do Public Cloud Firewalls Protect Your Network? 


The main function of a public cloud firewall is to prevent malicious attacks against your network. By blocking any threats before they reach your network, you can ensure that your systems remain safe. 


This is because the firewall inspects each incoming packet of information to see if it matches any of the rules set up by the administrator. If it doesn’t match any of these rules, then it is blocked. 


If a threat is detected, the firewall can also block it so that it cannot harm your network. For example, if someone tries to send spam emails using your company’s domain name, the firewall will block them. 


This helps keep your network secure because it prevents hackers from accessing your system. 


How To Choose a Public Cloud Firewall 


Choosing a public cloud firewall isn’t always easy. There are several factors to consider, including: 

  • Cost 

  • Security features 

  • Support options 

  • Performance 

Let’s take a look at each of these points in turn. 


Cost 


One of the most important considerations when choosing a public cloud firewall is cost. You need to make sure that the price is right for your budget. 


You don’t want to pay too much for a product that won’t provide adequate protection. On the other hand, you don’t want a cheap product either. 


There are two ways to find out whether the price is fair. First, check the reviews of the product. Look for feedback from people who have already purchased the product. Also, make sure that there are no hidden costs. Some companies charge extra fees for additional services, which aren’t included in the original price.
