2021 TOP3 metric description
TOP3 metric reflects how successful a vendor was inindependent tests within a calendar year.
The main characteristic of success is a TOP3 score that show s how many times a vendor w ith its products gained
the first, second, or third place in independent tests they participated in w ithin a reported period. The TOP3 score iscalculated by dividing a vendor’s TOP3 counter by a vendor’s Participation counter.

The TOP3 score is determined for each participating vendor separately and then compared to each other.
1.

Depending on a test, final test results may vary from giving aw ards for participating vendors to providing only alist of their detection rates and false positives.
A vendors' TOP3 counter is incremented either for w inning an aw ard or ranking in the first three places in atest. It cannot be incremented both for receiving the aw ard and one of the first three places. Several vendors
can achieve equal results in detection rates, or summary results, or w in aw ards of the same grade. In this case,the vendors share the same place in the same test. In case of detection rates or summary results, the place of avendor w ith the low er result is calculated as “number of higher ranked vendors + 1”. For instance, the sequence“1,1,2,3” is not possible, w hilst “1,1,3,4”, or “1,2,2,4”, or “1,1,1,1,1,6” are. In the latest sequences TOP3 counter
w ill be incremented for bolded vendors only.

2.

A vendor’s Participation counter is incremented each time one of its products participates in atest/review /overview . In some tests several products of one vendor can participate in the same test. In thosecases, since all products increment the vendor’s Participation counter, the Participation counter can be higher
than a total number of tests.

Only those w ho participate in 35% or more of the total number of tests have their results represented in the chart.
The deadline for submitting scores attained in 2021 w as February, 1st 2022, w ith no option to add any test/review
after this date.

Among the security vendors participating in the TOP3 measurements are: Avast, AVG, Avira, Bitdefender,Blackberry (Cylance), Broadcom (Symantec), BullGuard, Crow dStrike, ESET, F-Secure, G DATA, McAfee,Kaspersky, Microsoft, NortonLifeLock, Palo Alto, Panda, Sentinel One, Sophos, Trend Micro, Quick Heal andVMw are (Carbon Black). A complete list of participants appears at the end of this document.

*Broadcom (Symantec) participated in only 23% of the total number of tests, but weconsider it valuable to have the vendor’s results represented in the chart .
