Virtual Firewall: Keep Your Data Safe!

The internet is an amazing place. It’s also a dangerous one. For years, companies have been trying to come up with solutions that will keep your data safe on the web. There are many ways that hackers can get into your computer and steal information; it may be as simple as clicking on a malicious link or installing malware onto their system. A virtual firewall is something they’ve created to help combat this problem. This blog post will teach you what they are, why they’re important, how they work, and more.

What is a Virtual Firewall?

A virtual firewall is a software program that acts as an additional security measure on your computer. They were created for environments where setting up a hardware firewall was difficult or not possible. That’s where virtual firewalls come in handy as they are software.

Virtual Firewall creates a sort of wall between you and the outside world, protecting your data from malicious viruses or hackers who are looking to steal it. 

Virtual firewalls have become very popular over the years because they provide another layer of protection for people’s information online. There are many different types out there so companies constantly try to come up with new ways to keep their customers safe.

How Does a Virtual Firewall Work?

A virtual firewall works by allowing you to control incoming and outgoing data on your computer. When the program is first installed, it creates a sort of map for itself that tells it what can be allowed through and where to block off access. 

It does this based upon rules set up within the software; these tell it whether or not certain actions are allowed or disallowed in certain circumstances (such as if someone tries to connect with your system from an unknown source). If there isn’t already a rule created for whatever action they’re trying, then the firewall ignores them completely.

What Are The Types of Virtual Firewalls?

There are several different types out there, each with its pros and cons. The main two that people think about when they talk about virtual firewalls are host-based and network-based. Let’s take a look at the best one in each category:

Host-Based Security Systems  

These are installed onto an individual computer’s software (or even part of its hardware) so whoever is using this device will have these extra security measures available. 

They’re very effective but can also cost quite a bit because they’ve got every single piece of data coming in or going out. 

It’s also more difficult to administer these types of firewalls, so they’re usually only used by big businesses that have the necessary funding and employees available for upkeep.

Network-Based Security Systems  

Network-Based Security Systems are installed onto networks instead of computers; this makes them easier to manage because people just have to look at what information is being sent over their system as a whole rather than dealing with systems one at a time. 

However, network-based virtual firewalls are not nearly as effective since hackers can still get in if they know which ports need to be open on your firewall (or even hack you through an unprotected wireless internet connection). 

They are less expensive but don’t provide much protection against cybercrime.

What Is The Difference Between a Virtual Firewall and a Hardware Firewall?

A virtual firewall  is entirely software-based, meaning it’s going to be available on whatever device you’re using at the momentA hardware firewall needs to have its dedicated piece of equipment (like an external hard drive) before its security features are active
Software firewalls need to run off another program so if someone manages to get past this one then they can more easily access the other programs on your system.There is no way for hackers to crack into these types of firewalls unless they do something like destroying the physical product itself since all of the information will stay within this one unit rather than being split up between multiple machines.
Virtual firewalls are more expensiveHardware firewalls tend to be a lot cheaper since they don’t require any extra software or processing power from another machine

If you’re looking for something that’s going to give you some more advanced protection abilities (like being able to block certain websites) then it may be worth investing in some of the top-of-the-line virtual firewall software. Even though there are many benefits when it comes to using physical security measures like locks and alarms, nothing beats having an entire wall separating you from intruders.

Benefits of Using a Virtual Firewall

Here’s just a handful of reasons why you should consider adding one onto your system:

  1. They Can Block Unauthorized Applications from Accessing Your System

This is especially useful if someone sends out an app that looks like it does something completely different than its actual function (like trying to steal all your personal information and send it back to them). If this happens then the application will be blocked off immediately because it has no permission whatsoever; however, for those who don’t know how these types of attacks work or aren’t tech-savvy, this can be a massive inconvenience.

  1. They Can Block Unauthorized Devices from Accessing Your System

If you’ve ever used a USB and plugged it into someone else’s computer then you know just how quickly data can be stolen. This is especially true if the other person has something like keylogger software installed on their machine; this way they can see absolutely everything that pops up whenever you’re using your keyboard (which also means they’ll have access to anything private such as your email, bank accounts, etc.). Blocking off certain devices will keep everyone safe!

  1. They Keep You Safe During Public Wi-Fi Use 

Even if you try to be as careful as possible while using public Wi-Fi, there’s always the chance that someone could still access your computer without you even realizing it. This is because hackers can easily create fake networks to get their hands on all kinds of private information; however, a virtual firewall will automatically block off any suspicious activity so this doesn’t happen.

  1. They Can Protect Your System from Viruses and Other Malware 

Since they’re designed specifically to keep people out, these types of firewalls are going to have much more advanced security measures than just about anything else available on the market today. If something does manage to sneak past whatever other type of protection you have then it won’t matter since your firewall should take care of it.

  1. They Can Help You Recover from a Hack

Sometimes even the best firewalls can’t stop hackers completely because they’re just that good. That’s why many of the software have backup systems in place which will still allow you to gain access to your computer after an attack; this way you’ll be able to fix whatever damage has been done without too much hassle. The last thing anyone wants is for their entire system or network to be taken down when something like this happens so having backup measures in place is beneficial.


Overall, there are some pretty great benefits when it comes to using virtual firewalls. They’re not only extremely easy for just about anyone to use but they can also help you get your entire system back up and running after an infestation of viruses or malware has taken place; this way you don’t have to worry too much about any data loss (which is always a good thing!).
