Provides a user-friendly experience compared to other endpoint security solutions and excellent real-time threat protection but poor customer service and support
I appreciate the user interface (UI/UX). Kaspersky provides a user-friendly experience compared to other endpoint security solutions. Additionally, Kaspersky offers a large number of robust default policies, such as USB blockage. I really like this feature. Kaspersky provides excellent real-time threat protection. Your main database server is connected to the Kaspersky server, preventing zero-day exploits, advanced threats, and APTs (Advanced Persistent Threats). This protects your confidential data. Importantly, Kaspersky now uses signature-less technology, a crucial feature for combatting modern viruses, malware, and threats that have evolved beyond traditional signature-based detection. Before 2011, endpoint security worked on signature-based detection. Kaspersky is working on signature-less technology, so I really like that.

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.
