Senior Technical Manager at Flexaccel
Remote access has become seamless and secure while deployment remains simple for our users
Performance could be improved today. People are now moving toward SASE, which stands for Secure Access, Secure Edge Solution. Fortinet also has that offering, which would be easier since it operates through the cloud, acting as a first line of defense. When the user connects to the internet, they connect to the cloud first for posture assessment and monitoring before connecting to the outside world. The impact is significant because nowadays people are adopting SASE. During COVID time, many users were trying to connect back to their office, causing the performance or CPU utilization of the firewall to increase tremendously, which slowed down performance. I have not worked with endpoint telemetry in Fortinet FortiClient that could have been helpful for threat mitigation.
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.
