Windows Defender Vs Bitdefender | Independent Comparison [2019]

Windows Defender or Bitdefender, which antivirus software is a better pick in 2019?

Our experts have put together this comprehensive Windows Defender versus Bitdefender comparison to help you make a wise decision.

Every device we use today, for personal or professional use, is supported by hackable technology: our phones, computers, credit cards, bank accounts, social media accounts, even smart home appliances, and home security systems.

Everything is within easy reach of hackers UNLESS … you are well protected.

There’s a hacker attack every 39 seconds that affects one in three Americans each year. In 2018, around 700 million people became victims of one or another type of cyber-attack.

In such a situation, it’s crucial that you get yourself top-quality protection if you want to be safe in today’s digital environment. And this security can only come from a premium antivirus software.

But what about the free software you already have installed on your device? Well, that’s not enough. Freeware only provides an elementary level of protection against some known malware types. But it lacks the advanced security solutions that only premium software can offer, such as ransomware protection, behavioral analysis, multi-layer protection, etc.

Our today’s guide gives you a detailed comparison between two famous brands i.e., Windows Defender and Bitdefender. Let’s find out which one of these is better at protecting you against malware and cyber-attacks.

Let’s get into details.

1. Features

Features are one of the first things a customer notices about antivirus software. As more features means better protection, we are going to explore which of our products offers a more comprehensive feature set.

Windows Defender’s Features

Windows Defender is the built-in antivirus program for Microsoft Windows users. So if you’re already a Windows user, you don’t need to install this program. You may need to update your software if you’re using an older version.

If, however, you wish to install another antivirus program, Windows Defender will automatically turn off and you can run the new software without any interference.

Windows Defender only offers a single built-in version that provides the following features:

  • Firewall – guards against malware and hacking attacks.
  • Malware Definition Updates – probably the only free software that gets regular malware definition updates against emerging threats.
  • SmartScreen – blocks phishing websites and corrupt downloads. However, this feature is only compatible with Microsoft Edge Browser.
  • Find My Device Function – helps to locate stolen PCs or laptops. You can also use this function to lock your device or erase your sensitive data.
  • Parental Controls – monitor the online activities of your children and block their access to harmful content or unwanted websites.

Bitdefender’s Features

The first product from Bitdefender is a freeware called Bitdefender Free Edition. This program is only compatible with PCs and offers barebones protection against malware attacks compared to paid tiers that start with Antivirus Plus.

Bitdefender Antivirus Plus is a PC-only program, but it provides a number of useful features against the latest malware crimes:

  • Advanced Firewall – provides complete and proper protection against all kinds of malware attacks, including botnets, rootkits, Trojan horses, phishing attacks, and worms.
  • Ransomware Protection – shields against ransomware attacks by encrypting your personal and financial information on the internet.
  • Limited VPN – offers temporary anonymity while browsing as well as hides your actual location.
  • Secure Internet Browser – saves you from phishing and fraudulent websites.
  • Password Manager – saves your passwords and other related information in a digital space to protect it from hackers.

The next product from the company is the Bitdefender Internet Security suite. Along with everything from the previous product, this suite also offers some additional features such as:

  • File Encryption – encrypts your important files and documents and blocks unauthorized access to them.
  • Vulnerability Checker – scans your home network for security gaps and fixes them instantly.
  • Parental Controls – Save your kids from unpleasant digital experiences by monitoring their online activities and restricting their access to unwanted content.
  • Webcam Protection – prevents your family against webcam malware attacks by restricting unsanctioned access to camera settings.

The next tier of protection comes with Bitdefender Total Security, the most premium product from the company. This suite comprises the most advanced features and comprehensive protection from the company. Features included are:

  • Anti-Theft Function – locates missing or stolen devices that are subscribed to Total Security.
  • Wi-Fi Advisor – notifies about unsafe public Wi-Fi networks and secures against malicious threats across these channels.
  • Optimizer – frees up valuable system space by organizing temporary files and deleting junk data.
  • Photon Technology – this feature functions a few steps ahead of an optimizer by analyzing both hardware and software to free up system resources so the users can experience the optimal processing power of the device.
  • Rescue Mode – reboots the system if it detects a virus has managed to lodge itself on your computer’s core code without deleting essential files on your system.

Total Security is also available in the family version if you want all of your home devices protected under a single subscription, called Bitdefender Family Pack. This suite provides complete peace of mind for your entire family.

For Mac-users, Bitdefender offers Antivirus for Mac. This product provides complete protection against Mac-related cyber threats.

All Bitdefender users can enjoy top-quality customer services by contacting the company via phone, online chat, or email.

Bitdefender Security Suites and Features

Bitdefender also offers business-related antivirus security. You can go here for information about that.

Winner: Bitdefender. It is evident from the above comparison that Bitdefender offers complete, all-encompassing security solutions compared to Windows Defender’s limited features.

2. Anti-Malware Protection

Naturally, antivirus software should provide top-notch anti-malware security. We’ll look at some independent tests to see how both products fare in this area.

We’ll first look at the Protection Test results from the AV-TEST Institute that conducts evaluations in Protection, Performance, and Usability categories. All categories are rated on a scale from 1 to 6.

Windows Defender scored a perfect 6/6 score on the Protection test.

Bitdefender wasn’t behind because it also gave a super performance with a 6/6 score.

Next, we’ll consider two different evaluations from the AV-Comparatives, another testing organization. This organization rates the contenders in the form of awards. For their Real-World Protection Test, Windows Defender was in second place with the ADVANCED award, while Bitdefender got the highest rating from this source as well with an ADVANCED+ award.

The other assessment from the same organization is the Malware Protection Test. This assessment puts antivirus software to the test against malware types transported via network routes or removable media.

Malware-Protection-Test-Results-AV-Comparatives-Evaluations-March-2019

In this test, both Windows Defender and Bitdefender were at par receiving the ADVANCED+ awards.

Winner: Bitdefender. Windows Defender gave excellent performance in two independent tests, but Bitdefender was at the top in all three evaluations.

3. Impact on System Speed

Sometimes an antivirus program tends to drag your system speed just as much as a virus would do. But of course, you wouldn’t want that, would you?

So, let’s see what kind of impact both Windows Defender and Bitdefender have on the system speed.

In the Performance Test by the AV-TEST Institute, Windows Defender was just short of the perfect score with a 5.5/6 rating.

Windows Defender Performance Test Results AV Test Evaluations July August 2019

Bitdefender received a full score with 6/6 points.

Next, we’ll have a look at the Performance Test results from AV-Comparatives. Here, Windows Defender was not so impressive as it received the third-place STANDARD award. However, Bitdefender remained in the lead with the highest ADVANCED+ award.

AV-Comparatives-Performance-Test-April-201

Winner: Bitdefender. Bitdefender consistently demonstrated in the evaluations that it had minimal effect on system performance, whereas Windows Defender was inconsistent in its performance ratings.

4. User Interface

The user-interface doesn’t affect the working of antivirus software, but it does affect what the user perceives about it. Naturally, a user would favor a product that has a more functional interface.

Let’s see how Windows Defender and Bitdefender compare on this metric.

Windows Defender has a pretty simple user interface that displays all the primary functions on the Home screen with their updates. The same functions can also be accessed from the panel on the left-hand side of the screen.

There’s a button at the bottom of the screen to start a quick scan. Using this interface is quite easy as it doesn’t offer any challenges in terms of layout.

However, you can’t customize the interface, nor can you pre-schedule your scans. You’ll have to start a scan manually every time you want to see a threat analysis.

Windows Defender Antivirus Interface

Now let’s have a look at Bitdefender’s interface.

Bitdefender is known for its sleek interface and neat look. You can access most of the major functions from the Home screen, including “Quick Scan” as well as “Vulnerability Scan.” A narrow side panel gives access to other features and utilities.

Bitdefender also provides the option to customize the look of the software interface completely. You can also schedule your scans according to your preferred time. Overall, the interface is highly intuitive, easy to operate, and ideal for all kinds of users.

Bitdefender Antivirus Interface

Winner: Bitdefender. Bitdefender fulfills where Windows Defender lacks. Not only do you get the customization option from Bitdefender, but you also get the choice to schedule your scans as required.

5. Pricing

Pricing is something every user is conscious about. When you’re paying for something, you want it to give you a justifiable value for your money. Let’s see how today’s products impact our wallets.

Windows Defender

Bitdefender

Entry-level Product Windows defender is a free-of-cost program that comes built-in with Windows operating systems. Bitdefender Antivirus Plus costs $29.99 for the first year for up to 3 Windows devices.
Premium Product Bitdefender Internet Security costs $34.99 for the first year for 3 Windows devices.
Bitdefender Total Security costs $39.99 for the first year for 5 Windows, Macs, and mobile devices.
Family Suite Bitdefender Family Pack costs $54.99 for the first year for 15 Windows, Macs, and mobile devices.

Winner: Bitdefender. You don’t have to pay anything with Windows Defender. Still, in terms of the value, you also don’t get as much as you do with Bitdefender that provides top-grade security for extremely reasonable pricing.

6. Popularity

Now we’ll see what percentage of antivirus market share is held by both our products. We can find that out by looking at survey reports from two well-known organizations that regularly conduct market survey i.e., OPSWAT and STATISTA.

First, we’ll consider the market survey report from OPSWAT that shows Bitdefender at a market share of 11.2%. However, Windows Defender falls somewhere at the bottom with several other brands, all holding a collective market share of 10.66%.

Now let’s see what Statista survey report presents in its August 2019 edition. According to this report, Bitdefender holds a share of 10.17%, whereas Windows Defender is once again nowhere to be seen among the top-ranking brands.

OPSWAT Antivirus Market Share

Winner: Bitdefender. The above survey reports leave no doubt in our minds that Bitdefender is one of the most popular brands, whereas Windows Defender doesn’t even come close in recognition.

7. Customer Ratings

Next, we come to the actual existing users of these products and see how satisfied they are with their overall experience. Let’s look at the customer satisfaction ratings from two reviewing websites to compare our brands.

The first of these organizations is Consumeraffairs.org. This website gathers customers’ feedback and averages it out on to a 5-star scale. Bitdefender scored a modest 3-star rating on this website.

Windows Defender was not rated on this website, probably for the lack of customer responses.

Now let’s look at G2 for its antivirus ratings that are spread on a 1-5 point system as well as a 5-star scale. Here, Bitdefender scored a close to perfect score with 4.8 points.

Unfortunately, Windows Defender wasn’t rated on this website, as well.

Winner: Bitdefender. Once again, Bitdefender is ahead of the game, scoring favorable ratings from two different sources, whereas Windows Defender was nowhere to be seen.

Bottom Line

We have seen that Bitdefender has consistently won all the categories against Windows Defender with exceptional ratings in Malware Protection and System Performance. This shows that Bitdefender is undoubtedly a much better product compared to Windows Defender.
