Have maintained strong endpoint protection through behavioral analysis and daily monitoring
I previously mentioned that Kaspersky Endpoint Security for Business doesn't have built-in DLP, which was a concern. I think they could add it in the future; however, antivirus cannot provide a proper DLP solution, but they can offer a mix of DLP, similar to Trend Micro Apex One, which provides some sort of DLP file management. Nonetheless, we need a proper DLP solution such as Forcepoint or Symantec, whichever suits us. We'll be conducting performance evaluation in the next quarter while working on other projects. More value means a better GUI, user interface, and comprehensive reporting capabilities. In Sophos, we receive a daily system-generated report about what is happening, plus an alert system. The reporting system in Trend Micro is also excellent; I receive an email every day at 10:00 AM with a report for the last 24 hours.

Product deployment protects assets but needs improvement in system support
I am doing maintenance for Microsoft Defender for Business, and I'm currently working with it. We don't need to use the latest version of Microsoft Defender for Business. We still use the latest virus definition file that Microsoft Defender for Business has automatically updated. We implement a basic update mechanism. Our compliance division manages how many servers and PCs we have and whether those servers have antivirus solutions. I am not certain about how Microsoft Defender for Business helps with AI-driven security strategies. I just use it normally and don't know if it uses AI technology. I rate Microsoft Defender for Business a six out of ten.
