Bitdefender or BullGuard, which antivirus software is a better pick in 2021?

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

The onslaught of malware threats is so rampant and ruthless that you’ll find it in the most unexpected and innocent of places. It’s mind-boggling.

Did you know that researchers have recently discovered a new attack campaign that hides malicious code inside WAV audio files? You heard that right. Is it any surprise that a new malware attack happens every 14 seconds these days? And this gap is expected to reduce even more by 2021 to just 11 seconds.

In this situation, the wise thing is not to take anything for granted and employ the highest level of security to guard personal and financial information of yourself and those you love.

Most of us rely on freeware against malware. But given the complexity of these viruses, free software isn’t well-equipped to detect and remove them.

What you need is a premium antivirus software that extends multi-layered protection to block malware entry through a multitude of routes. Premium software provides an array of advanced features and modern technologies that enhance digital security and offer extra layers of protection.

It is the only way to ensure your safety on the internet and that of your loved ones.

Winner: Bitdefender. BullGuard offers some really nice features, including behavioral engine and cloud backup, but in comparison, Bitdefender provides much more extensive anti-malware and system enhancing coverage. Therefore, Bitdefender wins this category.

2. Anti-Malware Protection

There’s hardly any feature more important than malware protection since it’s the chief objective of an antivirus software. So, let’s see how well Bitdefender and BullGuard can protect their devices.

We’ll use independent test results from the AV-Test Institute and AV-Comparatives for our comparison.

The first of these, The AV-TEST Institute, assesses antivirus products in three different categories of Protection, Performance, and Usability, carrying grades from 1-6, 6 being the highest score.

For their Protection category, Bitdefender achieved the highest score with a 6 out of 6.


BullGuard received the ‘almost perfect’ 5.5/6 score.


AV-Comparatives is another testing organization that conducts the Real-World Protection Test, rating different products in the form of awards. Bitdefender received an Advanced+ award for this assessment. Whereas, BullGuard didn’t participate in it.


Evaluating different products for protection against viruses transmitted through network drives and removable storage media, Malware Protection Test is another assessment carried out by AV-Comparatives. Here as well, Bitdefender was ahead of the game with the ADVANCED+ award, while BullGuard wasn’t part of this test as well.


Winner: Bitdefender. While BullGuard did show a good performance in the AV-Test evaluation, it wasn’t present for the AV-Comparatives’ tests, leaving the field open for Bitdefender to claim this category.

 3. Impact on System Speed

The second most important factor to consider when choosing an antivirus software is its ability to engage minimum resources on your system. So, let’s now look at the system performance related test results from the same organizations.

AV-TEST Institute ran its Performance Test, once again, with a 6 out of 6 metrics. Bitdefender scored a perfect 6 out of 6 score in this test, as well.


BullGuard was a little behind with a 5 out of 6 score.


AV-Comparatives carried out their own Performance Test. Here as well, Bitdefender got another ADVANCED+ award, indicating high performance on regular computers running normal operations.


As mentioned above, BullGuard was not a part of AV-Comparatives evaluations.

Winner: Bitdefender. BullGuard was behind Bitdefender in the first assessment while it didn’t even show up for the second one. So, Bitdefender wins this category as well.

4. User Interface

The interface of antivirus product commands a big impact on users as that’s how they interact with the software. Let’s see what kind of user-experience both our brands bring to the table through their interfaces.

The first thing you notice about the Bitdefender interface is the clarity of the design and its intuitiveness. The interface consists of distinctive panels and icons that provide all the information and access points for different functions and settings.

Bitdefender also offers customization to modify the look and settings of the interface to suit your preference. This interface is equally efficient for both light and seasoned users.

Bitdefender Antivirus Interface

Now we’ll turn our attention to the BullGuard interface.

BullGuard interface is simple in design yet uses the entire Home screen to display all the necessary information needed by a user.

Big rectangular blocks take up the entire screen and give access to different features and functions, such as antivirus, firewall, backup, PC tune-up, parental control, etc. These blocks also show current updates about the relevant function.

Each block also contains drop-down menus to access settings for that specific function. Overall, the interface is simplistic, intuitive, as well as easy to understand and navigate.

BullGuard Antivirus Interface

Winner: Both. Both interfaces are complete in their designs. Bitdefender does offer customization options, but BullGuard has a design that works for both casual and expert users as is. So, both win this category.

5. Pricing

Both Bitdefender and BullGuard’s entry-level products cost the same. But going up the security ladder, we see that BullGuard’s prices get steeper and steeper compared to Bitdefender.

Winner: Bitdefender. It is clear from the pricing table that BullGuard’s later products cost higher compared to Bitdefender’s. Even though Bitdefender provides more value with each product.

6. Popularity

Our next criteria for today’s brands is their overall popularity among users. To gauge that, we are going to use survey reports from two famous companies, OPSWAT and Statista, and find out which one is more popular.

According to OPSWAT’s recent Windows Anti-Malware Market Share Report, Bitdefender commands a good 11.2% market share. Whereas BullGuard doesn’t show up among the top 10 most popular products. It falls among all other products that collectively take up 10.66% of the market share.

OPSWAT Antivirus Market Share

Looking into the market survey report from our second source, Statista, we see that Bitdefender takes up 10.17% of the market share. Once again, BullGuard doesn’t show up on the list.

Winner: Bitdefender. The survey reports make it crystal clear that BullGuard is nowhere near as popular as Bitdefender, which commands a huge chunk of the market share.

7. Customer Ratings

Our final criteria for today’s comparison is customer satisfaction. To gauge our brands on this metric, we’ll take help from two reviewing websites: Consumeraffirs.org and G2.

Consumeraffairs.org is a review collecting company that ranks products on a 5-star scale based on the reviews they get. Bitdefender, it turns out, has three out of five stars here. While BullGuard doesn’t have any reviews on this site as of now.

Next, we are going to look at ratings on the G2 website. As per this source, Bitdefender has an excellent 4.8 out of a total 5 score. As it turns out, BullGuard hasn’t been rated on this website either.

Winner: Bitdefender. Since BullGuard doesn’t have any ratings, we can’t assess customer satisfaction for it. However, looking at both ratings for Bitdefender collectively, the customers seem relatively satisfied with it.

Bottom Line

BullGuard did manage to take on Bitdefender on the interface design, but that’s about the only area where it did that. Bitdefender was ahead of BullGuard in all other categories with better features, better anti-malware and system performance, better pricing, and more.
