Featured Reviews

Public Cloud Engineer at Prudential
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.

Provides stable and resource-efficient protection but lacks clear modern security features
Symantec Endpoint Security Enterprise is highly compatible and rarely causes disruptions in production. It operates transparently and is easy to maintain. The automated response feature helps to mitigate breaches effectively. When comparing with ThreatDown agent, I have noticed that ThreatDown detects behaviors more readily and flags suspicious user activities more clearly. While Symantec Endpoint Security Enterprise remains effective, ThreatDown's user interface is more manageable and provides a clearer system overview. The management interface is crucial for maintaining Symantec Endpoint Security Enterprise effectively. A significant advantage of Symantec Endpoint Security Enterprise is its lightweight resource usage. It consumes less memory, CPU, and IO compared to alternatives such as ThreatDown and Bitdefender.
