Alessandro Spiandore - PeerSpot reviewer
Proprietario at IL COMPUTER snc
Long-term licensing has provided reliable lightweight protection for commercial customers and maintains strong performance without disrupting existing security tools
Kaspersky Total Security is a lightweight solution that does not slow down Windows. In many years of use for my customers, I have not had any broken software or other problems. Safe Money technology is available in the product, but I do not use it because my customers have other security solutions that intercept malware before Kaspersky on the firewall and networking firewall of LAN. I sell the various solutions of next generation, Optimum, and Advanced through MCP licensing.
Takayuki-Umehara - PeerSpot reviewer
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.
