Cost efficiency and ease of setup define network management while potential improvements in complexity handling are noted
Optimizing and configuring for network segmentation is the biggest thing for helping with segmenting traffic management. Configuring QoS on Linksys is pretty easy, especially compared to Cisco QoS, which I am certified in, as it helps ensure that the bandwidth for voice or other applications doesn't bleed over into the data links. In the past, Linksys has been pretty good at network protection, segmenting off that protection for unauthorized access or cyber threats. Cost savings and ease of use are the benefits I've seen from Linksys. It's a little bit less complex to set up and configure compared to Cisco switching. I utilized the VLAN support feature in the Linksys switches. A lot of the networks I have were broken up by VLAN, and I definitely configured them for different VLANs. The best feature of Linksys in my opinion is cost, as they tend to be more cost-effective compared to larger switches or Cisco switches.

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.
