Bitdefender or Kaspersky, which software is a better option in 2021?

Read this ultimate Bitdefender versus Kaspersky comparison to make a smart choice.

From small-time hackers looking for mischievous amusement to high-level cybercriminals eyeing to loot big companies, data and privacy of both individuals and companies are always at risk of being compromised.

According to a recent report from RiskIQ, 1,274 new unique pieces of malware are created each year, 156 million phishing emails are sent every day, and 100 new phishing pages are created each minute.

The global threat management company also found that in every single minute, 1,861 people fall victim to cybercrime, 9.2 new instances of malicious advertising attacks are executed, and $1,138,888 is stolen by criminals.

The data suggests that cybercriminals keep looking for new ways to attack your devices. Therefore, as long as you are connected to the Internet, you must need an antivirus suite that gives you ultimate protection.

An antivirus – as the name might suggest – doesn’t only protect you from viruses, but it also safeguards you against other malware types, including ransomware, spyware, trojan horses, bots, worms, and more.

But that’s not all. Most antivirus products these days go beyond malware protection. They also provide features like parental controls, VPN, secure browser, password manager, file shredder, identity theft protection, system speed optimization tools, and much more.

However, almost all of these features are included in premium antivirus suites. They may cost you a few bucks, but the peace of mind they give in return is just priceless.

You may consider free antivirus software as well, but again, it provides only basic protection.

Now, let’s dig into the details.

1. Features

‘The more, the better’ applies to most good things in life, as it does to antivirus products. The more a product packs security intensive features into it, the more comprehensive the overall protection becomes. Let’s see what features are jammed into different Bitdefender and Kaspersky security suites.

We’ll start with Bitdefender.

The first offering from the company is Bitdefender Free Edition, which is a Windows-only product. The edition provides basic-level protection against different malware, but that’s about it.

We’ll move onto Bitdefender Antivirus Plus 2021, the entry-level premium product from the company. Also, a Windows-only software, it comes with features such as:

  • Comprehensive protection against all kinds of malware threats.
  • You also get the benefit of secure and anonymous browsing via a limited-use VPN, which prevents hackers from tracking you.
  • An Anti-Fraud module protects your financial information and provides you safe online shopping experience.
  • Also included is a File Shredder. This feature permanently deletes your confidential information so no one can access it.
  • A Vulnerability Scanner fixes network security gaps to keep you well protect from threats across this channel.
  • There’s a password manager that secures your password and saves your information from being hacked.
  • This product covers protection for 3 PCs with the option to add more if required.

Next comes Bitdefender Internet Security 2021, another Windows-only product covering up to 3 PCs. Apart from everything from the previous product, this package also includes:

  • A two-way firewall that protects your home network against any security weaknesses.

  • There’s an Anti-Theft utility that allows you to locate missing or stolen devices as long as they have this product installed on them.
  • This suite applies to Mac, Android, and iOS devices as well.
  • A single license of this product covers up to 5 devices.

Bitdefender Family Pack 2021 is essentially the same product as Total Security, only this suite is meant for families. The only difference is that the Family pack includes:

  • Advanced parental controls to monitor, restrict, and supervise your kids’ online activities.
  • Coverage for up to 15 devices (fair use policy applies).
Bitdefender Security Suites features

For Mac devices, the company offers a separate product: Bitdefender Antivirus for Mac. This product includes features such as:

  • Comprehensive malware protection against all Mac-related cyber threats.

Now let’s look at what Kaspersky has to offer in terms of a feature-set.

Kaspersky Free is the first software from the company. It has a firewall that provides some level of protection, but it is barely more than an introduction to the software interface and workings. So, let’s move to the paid tiers.

Kaspersky Anti-Virus is the entry-level, Windows-only product from the company. It includes features like:

  • A firewall that protects you from all kinds of digital threats.
  • Multilayer Ransomware Protection saves you from becoming a victim to money-related fraud and viruses.
  • There’s also a Gamer Mode that ensures distraction-free gaming or movie time by stopping pop-ups and notifications so you can enjoy your entertainment time.
  • A Vulnerability Scanner checks your security weaknesses and fixes them before you can fall prey to a hacker.

Kaspersky Internet Security comes next on the security spectrum. This suite includes everything from the previous product and some additional features:

  • A two-way firewall that provides you control over inbound and outbound connection requests and protects your system from connecting to unwanted apps.
  • There’s a hardened internet browser that offers secure browsing for you.
  • The suite also provides a secure VPN allowing anonymous browsing.
  • Webcam protection is also part of this suite.
  • Also included in the suite is a Wi-Fi Network Securer so that you don’t encounter any threats on your home network.
  • This product is compatible with all Windows, Mac, and Android devices.

The highest tier of protection comes with the Kaspersky Total Security suite.Along with everything from previous packages, this product also offers the following utilities:

  • An extensive Parental control module, called Safe Kids, monitors children’s activity on the internet and blocks access to age-inappropriate websites. This utility ensures a safe browsing experience for your kids.
  • A password manager secures your sensitive information on your device restricting anyone accessing it.
  • A file shredder that permanently deletes any confidential information that you don’t want to be discovered.
  • You also get 2GB of cloud data storage thanks to Dropbox.

Kaspersky Security Cloud is another high-end product that includes everything from Total Security suite as well as:

  • An innovative ‘Adaptive Technology’ that lets you import and update security settings across devices to guarantee a smooth transition for you from one device to another.
  • The technology also includes the functionality to adjust its automated settings according to a change in your online habits.
  • There are two versions available with this product: Personal and Family.
Kaspersky Security Suites and Features

Kaspersky also offers several business-related antivirus products. Check out these products here.

Winner: Bitdefender. Kaspersky has a nice spread of features, but Bitdefender provides more features and much more functionality across its products.

2. Malware Protection

The core purpose of spending money on an antivirus suite is to get the best malware protection. If the security solution is weak in this category, there is no point of buying it no matter how good features offers.

Let’s see which among Bitdefender and Kaspersky is more worthy when it comes to malware protection.

We are going to take assistance from two best independent organizations – AV-Test and AV-Comparatives – to determine the winner.

First, let’s take a look at the findings of AV-Test. In its April 2020 Protection evaluation, the AV-Test Institute gave Bitdefender a perfect 6 out of 6 score, which bears testimony to Bitdefender’s outstanding malware protection capabilities.

Bitdefender Protection Test Results AV Test Evaluations Mar Apr 2020

Bitdefender protected against all the zero-day malware attack samples used in the test, including web and e-mail threats.

In comparison, Kaspersky was trailing behind with a score of 5.5 out of 6.

Kaspersky Protection Test Results AV Test Evaluations Mar April 2020

Unlike AV-Test, AV-Comparatives runs two different protection tests, namely the Real-World Protection Test and the Malware Protection Test.

The Real-World Protection Test is web-based, whereas in the Malware Protection Test the vectors can be USB or network drives where the malware is already on the disk.   

In the latest AV-Comparatives’ Real-World Protection Test, conducted in May 2020, both Bitdefender and Kaspersky delivered excellent performance and received the highest 3-star ADVANCED+ award.

Real World Protection Test Results AV Comparatives Evaluations Feb May 2020

In the March 2020 Malware Protection, again both companies bagged the maximum ADVANCED+ award.

Malware Protection Test Results AV Comparative Evaluations March 2020

Winner: Bitdefender. Both companies scored exceptionally well in all malware protection assessments, surpassing many other popular brands. However, Bitdefender is the winner here, as it was slightly ahead of its competitor in the AV-Test evaluation.

3. System Performance

A distinct quality of an excellent antivirus suite is that it uses minimal system resources so that your PC can perform other operations without a whiff of trouble.

Let’s see how Bitdefender and Kaspersky perform in this category in the light of independent performance evaluations.

According to AV-Test’s Performance Test results, issued in April 2020, both Bitdefender and Kaspersky received a perfect score of 6 out of 6, suggesting that their average influence on computer speed in daily usage is minimal.

Kaspersky Performance Test Results AV Test Evaluations Mar April 2020

AV-Comparatives, on the other hand, also conducted Performance Test in April 2020. Once again, both Bitdefender and Kaspersky performed flawlessly and received the maximum ADVANCED+ (3-star) award.

AV Comparatives Performance Test April 2020

Winner: Tie. Bitdefender and Kaspersky performed brilliantly in both independent evaluations, earning the highest possible score.

4. User-Friendliness

Just as an antivirus should be subtle in its impact on a computer system, the same idea should resonate in the design of its interface. For most of us, we don’t want to have complex operations for something that is supposed to be running quietly in the background.

So, let’s review both our companies’ user interfaces and see how they fit with that concept.

Bitdefender uses sharp contrast to divide its interface into two prominent sections. One of these sections is the black rail on the left-hand side that displays buttons for different functions and features. You can expand these buttons to get into more specific tasks.

Bitdefender User Interface 2020

The white screen, on the other side of the interface, takes up almost 80 percent of the space and houses large blocks that each signifies a different function. You can move or modify which utilities you want to see on the home screen in order of your liking. The interface is exceptionally intuitive and straightforward and yet hides detailed personalization functionality in its design. Basically, Bitdefender optimizes its design for both casual and skilled users in this way.

Now let’s see how Kaspersky’s interface compares.

Kaspersky has gone for a sort of open-frame design using green and whites as primary colors. A big horizontal green panel across the top of the screen displays security status with a light checkmark. However, if there’s an issue, the mark will turn to a red cross demanding your immediate attention.

Below this panel, different functions have been organized into two rows. You can easily access any feature from the home screen. If you want, you can further personalize your screen settings to suit your preference.

Kaspersky User Interface 2020

At the bottom of the screen, the interface displays your current subscription status and notifies you when it’s time for renewal. Overall, the design is easy to operate, intuitive, and very user-friendly.

Winner: Bitdefender. Both companies have intuitive, user-friendly designs. But Bitdefender offers a much more intuitive and customizable design functionality that is suitable for both casual users as well as skilled professionals.

5. Pricing

Pricing has a huge role to play on a customer’s purchasing decision. The simple truth is that most of us play on a budget. So, the more bang a company provides for your buck, the more you’ll prefer it.

Let’s begin with Bitdefender pricing.

  • Bitdefender Antivirus Plus costs $29.99 per year and protects 3 Windows PCs.
  • Bitdefender Internet Security costs $39.98 per year and offers protection for 3 Windows-only PCs.
  • Bitdefender Total Security comes at $44.99 per year and protects all devices including PCs, Macs, and smartphones.
  • Bitdefender Family Pack is priced at $59.99 per year and gives protection to up to 15 devices per household.

Bitdefender Family Pack$119.99/yearCheck here
Bitdefender Antivirus for Mac$59.99/year Check here

Now let’s take a look at how Kaspersky prices its products.

  • Kaspersky Antivirus costs $29.99 per year for 3 PC-only licenses.
  • Kaspersky Internet Security costs $29.99/year for 1 device, $38.99/year for 3 devices, and $51.99 for 5 devices.
  • Kaspersky Internet Security comes at $39.99/year for 1 device, $48.99/year for 3 devices, and $62.99 for 5 devices.
  • Kaspersky Security Cloud Personal costs at $49.99 per year, whereas the Family version at $149.99 per year. The Family pack is priced quite steeply, but it comes with 20 universal licenses, ideal for a big family with each member owning several devices.
Kaspersky Products Regular Price Discounted Price
Kaspersky Anti-Virus$59.99/yearCheck here
Kaspersky Internet Security$79.99/year Check here
Kaspersky Total Security$99.99/year Check here
Kaspersky Security Cloud (Personal)$89.99/yearCheck here
Kaspersky Security Cloud (Family) $149.99/yearCheck here
Kaspersky Small Office Security $149.99/yearCheck here
Kaspersky End Point Security Cloud$300.00/yearCheck here

Winner: Bitdefender. Both companies have priced their products within the same range for each tier. However, Bitdefender offers far more value for your money for its most premium product than Kaspersky, that too with an unlimited number of licenses.

6. Customer Satisfaction

If you want to know how quickly a company will solve your issues in the future, you need to look at their previous record. This record comes from existing customer responses. Let’s compare the findings from two independent websites that collect customer responses and compile them into an average feedback rating.

Our first source is the Better Business Bureau that issues its rankings distributed across a ranking scale from A to F. Bitdefender received an average C from this source while Kaspersky got a rotten F.

Now let’s look at the ratings from that compile its ratings based on a 5-star score. Both Bitdefender and Kaspersky scored an overall satisfaction rating of 3 stars, showing average customer service performance.

Winner: Bitdefender. Both companies received similar ratings from the second website, but Kaspersky was far worse in the first rating. So, Bitdefender is the winner here.

Final Thoughts

Both promise a high level of security and performance, but Bitdefender is superior choice thanks to its comprehensive feature-set, excellent malware protection, and zero impact on system performance. Also. Bitdefender’s plans are cheaper than Kaspersky’s.

Our recommendations: If you want to get the highest level of security and performance, there's no better choice than Norton, which protects over 50 million users worldwide.


After reviewing dozens of antivirus products from some of the biggest names in the cybersecurity realm, we believe that Norton 360 Deluxe is the best antivirus suite available on the market. It provides flawless anti-malware protection without slowing you down. Plus, you get almost all the advanced features you could ever want.


If you're willing to pay more for advanced identity protection features, we recommend Norton 360 with LifeLock select (only available in the US). It's a bit pricey but worth the price.

7 thoughts on “Bitdefender vs Kaspersky | Head-to-Head (2021)”

  1. I have had Kaspersky Total Security for several years and paid $49.99 per year.
    However, you should note that Kaspersky increased the cost in 2019 to $84.99 for the same protection suite. Thinking of switching to Bitdefender!

    1. Hey Peggy,

      Thanks for your comment. And yes, Bitdefender is the best option available right now for both Windows and Mac users. Don’t forget to buy through our link, you can get a special 50% discount. Plus, it will also help us with our work 😉

  2. I heard its very difficult to get a hold of Customer Service, thru email or phone. I am concerned because. I always end up getting locked out of my account and can never recover my password at a responsible time with my Current Webroot . DO they have this issue as I want to try another service as Webroot wants me to renew for 79.99 for one year with no dealer for current customers. Nervous of changing as I came from Norton before Webroot so I need more confidence on changing yet again.. Help any advice is helpful and yes I do use Windows 10

    1. Hello Olly,

      Thanks for your comment. Sorry for all the hassle that you have gone through. I would recommend you get Bitdefender. Their support is pretty good and their software is very intuitive and user-friendly. Make sure you to purchase through links on this page if you want to get the maximum discount and also support our work 🙂

  3. I would probably pick either Kaspersky or BitDefender over all other vendors (as of this writing), though I find BitDefender much less straightforward to use (for someone who likes to see what the anti-virus software is doing and have intuitive control over it).

    Your 2nd rank vendor, McAfee, is not good and should not even be in the top 5, and for me, this somewhat clouds your results. There are several sources to cite to support my statement. For example, MRTG-Effitas reviews software (apparently at a cost to vendors who want to be considered), and while they focus more on banking-related protection, they are pretty detailed in their testing methodology, and you can see from all of their reports, including the latest from 2019, that McAfee is terrible, and McAfee was clearly one of the worst of the products tested. I think it’s not good to recommend this vendor as 2nd overall with results like the ones MRTG-Effitas consistently shows. I would never recommend TrendMicro or McAfee for end-point protection.

    1. Hello Rob,
      Thanks for your comment. We usually base our results on tests conducted by AV-Test and AV-Comparatives — two best independent labs out there when it comes to antivirus software testing. We have put McAfee in the second place because of its consistent, exceptional performance in the independent tests.
