As explained in our August 2015 report, our market share reports now provide data on the market share of anti-malware vendors and products instead of focusing solely on antivirus providers. We believe this shift in our reports parallels the shift in the security industry towards developing products that offer protection from a larger spectrum of threats than just computer viruses. Anti-malware products offer protection from threats such as PUAs, ransomware, spyware, keyloggers and botnets that antivirus products do not always detect.
For this report, we analyzed the market share of 59 anti-malware vendors, and the following three anti-malware vendors came out on top: In first place, Microsoft with 15.9% market share, in second place Avast with 15.0%, and in third place Malwarebytes with 11.6%. Other vendors that appeared in the top rankings, listed in descending order, include (but are not limited to) ESET, Symantec, AVG, Avira and Kaspersky Lab. For the purposes of this report, only vendors that offer RTP capabilities were included in our data. A list of the top 12 anti-malware vendors and their corresponding market share can be seen in the graph above.
While the above comparison only includes data from products with real time protection (RTP) enabled, we also analyzed data for all installed security products, including those that may have expired or been disabled. In this additional data set, Malwarebytes is the leading anti-malware provider, with a market share of 14.3%. Microsoft and Avast follow, with 10.6% and 9.7% market share respectively.
Although Windows Defender is heavily saturated in the anti-malware product market, we exclude it because we feel that it does not accurately represent the user's product of choice as it comes pre-installed on many Windows systems and cannot be removed.
This section of the report covers the popularity of Windows encryption products detected on devices using Metadefender Endpoint Management. This is the first time this data has been included since our September 2011 Market Share Report. In our September 2011 report, the top three encryption products were TrueCrypt (22.29%), Bitdefender (21.69%), and Kaspersky (12.46%). For this report, Bitlocker takes an overwhelming lead with an 82.1% market share, followed by TrueCrypt at 3.8% and AVG Internet Security at 2.5%. Bitlocker holds the majority mostly due to the fact that it comes pre-installed on many Windows devices and thus is not actively acquired by the user. If Bitlocker is excluded from encryption product market share results, the top spot is taken by TrueCrypt with a 21.1% market share, followed by AVG Internet Security at 13.9% and Bitdefender Total Security at 12.8%.
Interestingly, TrueCrypt is one of the top three encryption products for Windows users, despite the fact that development of the product ceased in May of 2014. Because product development has stopped, so has support for security issues, leaving the product exposed to potential vulnerabilities. James Forshaw, a member of Project Zero at Google, recently exposed two critical flaws in the encryption product. When the development of TrueCrypt was ceased, warnings from its creators were issued explaining that there could be “unfixed security issues” in the program.
One of the reasons that TrueCrypt has remained popular for hard disk encryption among Window users is because the product is free and Bitlocker is not available for those using home editions of Windows. Home users account for 63.4% of the devices included in this report, which could account for the higher than expected popularity of TrueCrypt.
