OPSWAT releases quarterly market share reports for several sectors of the security industry. This quarter’s report includes both worldwide and North American market share and usage data for antivirus software and Windows Operating Systems, and for the first time, worldwide data for backup client software. The data used was collected between August 16, 2010 and November 15, 2010.

The Research

Data was collected from a sample of the estimated 100 million endpoints that employ the OESIS Framework. OPSWAT analyzed almost ninety thousand opt-in reports that were submitted between August 16 2010 and November 15 2010.

Data for this report was collected using the detection capabilities of the OESIS Framework as well as by searching for common applications in the OS registry on endpoints. Antivirus vendors and Backup Clients looking for inclusion in the OESIS Framework are encouraged to contact marketing@opswat.com to partner with OPSWAT through the OESIS OK Certification Program and ensure that they are fully supported.
