Industry leaders understand that an in-depth security strategy is required to combat attackers. Organizations are still using legacy antivirus (AV) tools that may be inefficient for IT staff and ineffective at stopping today’s threats.Pulse and BlackBerry surveyed 100 IT security executives to understand how they handle unknown malware threats and how they plan to improve preventative security tools. More than half (55%) of respondents say their IT staff are spending more than 5 hours per week administering and updating signature-based AV solutions. By comparison, only 47% of respondents indicated this was the case a year ago. Specifically, the number of respondents who say their IT teams spend 6-10 hours on updates and administration jumped from 28% to 41%.
