I'm able to transfer data over internet network security. With the GRE I'm able to transfer data within one bunch to another bunch in a public way, like the internet. The communication is encrypted and is private. It gives me added privacy.

Previously, anyone in the organization would see any data point in the wall. They could just go and connect their machine with that data point and could access the network. But now, even if someone came and tried that, they will not be given access.

There's a technology called SD-WAN that we would like to see. We are unable to handle multiple connections or to automatically load balance. I would like to have a feature that enables us to automatically prepare for load balancing.

We have a very bad experience on the support. They take too much time requesting logs, and they are not coming directly online to resolve the issues.

The routers, don't have like long-term tendency features, or higher availability features available for the IOS. It could also use a better user interface.

I wish it would be more like the next generation firewall technology. There should be more selection between the application and filtering.

I think setup could be one area for improvement, because sometimes we don't have people inside so we have to move to the place.
