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.

Secure remote access has protected diverse users while access controls provide precise permissions

The user interface of OpenVPN Access Server is good but can be improved. I would prefer to see it become more intuitive. I use Twingate as an alternative, and in Twingate, you see resources, while in OpenVPN Access Server, those would be IP addresses. You get to see dashboards and access views of who can access a particular resource or subnet. You can see who can access what resources from the user view, but you can also see the reverse, which is which resource can be accessed by what users. That reverse view would be a nice addition to have in a dashboard. Additionally, access logs associated with that resource would be helpful, so it would be beneficial to have different views for the same content. Beyond the positive aspects, I would like to see improvements in OpenVPN Access Server. Twingate offers a different approach to the same problem by moving more towards resource-specific resources and fine-grained zero-trust access, as opposed to entire subnets and entire networks. I would prefer to see views on resources. In the same way that we can define subnets, perhaps we could have views that describe what this particular subnet does and what this particular resource does. Then we can assign those resources and subnets to individual users and groups. It is more about granularizing the resources that can be accessed rather than simply bundling them under subnets or a list of subnets, which is the current approach. Apart from that, I would like to see UI enhancements in OpenVPN Access Server in the future. Making it more modern would be beneficial.
