Users only need to install the VPN and authenticate with their email address
I primarily use remote VPN solutions to connect securely. We have configured both site-to-site VPN and remote VPN, and it is connected to FortiClient Implementing this solution has streamlined time management in our organization. Without SSO, we would need manual configuration for each PC, but…
Takayuki-Umehara - PeerSpot reviewer
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.
