Intego Earns 100% Detection in AV-Comparatives 2021 Independent Testing

Posted on by

Intego Mac Internet Security X9 and VirusBarrier X9 - AV-Comparatives approved Mac security award 2021
In a recent publication from independent anti-malware testing firm AV-Comparatives, Intego Mac Internet Security X9 earned the coveted Approved Security Product award for 2021.

Intego detected 100% of Mac malware and 100% of Windows malware samples used in the test, which consisted of 538 recent Mac samples and 500 prevalent Windows samples.

Why independent testing matters

It is important to use an antivirus product that is independently tested and certified to ensure that it works as expected and meets rigorous standards. Not every tested product passes certification, of course. Professional testing by a neutral, independent third party is a good way to confirm that a product works well and performs as expected.

AV-Comparatives has been a leading independent antivirus testing organization since 1999. The firm has strict criteria for certifying security programs. When AV-Comparatives grants certification to a security program, this indicates that the product “has proven itself to be effective, honest, transparent and reliable.”

Review highlights

AV Comparatives APPROVED Mac Security Product award 2021AV-Comparatives only evaluated the anti-malware functionality of Intego Mac Internet Security X9, specifically VirusBarrier X9. The firm noted that Intego Mac Internet Security X9 also includes Intego’s NetBarrier X9 firewall, which was not tested.

Some highlights from the test include (emphasis added):

  • 100% score in Mac Malware Protection (VirusBarrier X9 detected all 538 recent Mac samples)
  • 100% score in Windows Malware Detection (VirusBarrier X9 detected all 500 prevalent Windows malware samples)
  • “The program’s interface makes the most important functions easy to find and use.”
  • “We found Mac Internet Security X9 to have sensitive and reliable on-access protection against malware.”
  • “Standard user accounts cannot take any risky actions” such as disabling protection features.
  • “Overall, the program is straightforward and reliable in use.”
  • “A simple but useful help feature explains the main functions using an overlay.”

Intego also met AV-Comparatives’ certification requirements for Mac PUA Protection. “PUA” is shorthand for “potentially unwanted application,” a loosely defined category that can include non-malicious files and software that has potentially legitimate uses. None of the Mac antivirus products that AV-Comparatives tested detected all of the nearly 800 files that the testing organization defined as “potentially unwanted.” Because antivirus vendors may disagree on whether some samples should be detected as PUA, AV-Comparatives’ minimum PUA threshold for certification is a 75% detection rate—but Intego earned a very respectable 97% score for Mac PUA Protection based on files that AV-Comparatives defined as potentially unwanted.
