Assessing the Effectiveness of Antivirus Solutions
How good is antivirus? How should enterprises invest in endpoint protection? Imperva collected and analyzed more than 80 previously non-cataloged viruses against more than 40 antivirus solutions. Imperva found:
- Antivirus solutions have a difficult time detecting newly created viruses While antivirus vendors may constantly work to update their detection mechanisms, the initial rate of detection of new viruses by antivirus solutions in the study was less than 5%. Antivirus solutions in the study were unable to provide complete protection since they are unable to keep up with virus propagation on the Internet.
- Antivirus solutions lag in updating signatures In some cases in the study, it took anti-virus solutions up to four weeks following the initial scan to detect a virus.
- Investment in antivirus is misaligned In 2011, Gartner reported that consumers spent $4.5 billion on antivirus while enterprises spent $2.9 billion, a total of $7.4 billion or more than a third of the total of $17.7 billion spent on security software. In addition, certain freeware solutions in the study proved equally or more effective than paid solutions.
