Room For Improvement

Cisco IOS SSL VPN requires improvements in language support, pricing, GUI, compatibility, deployment processes, and enhanced remote access options.
OpenVPN Access Server needs improvements in security, interface, pricing, stability, compatibility, and admin tools to enhance user experience.
There have been issues with operating systems where newer updates cause problems with backward compatibility.
Technical Services Lead at Telenet Solutions
I believe Cisco could support easier configuration and having tools that allow for easier management and configuration.
student at a university with 1,001-5,000 employees
Lastly, it would be awesome to see native support for newer, lighter protocols through WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency.

Additionally, native support for newer, lighter protocols like WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency would be beneficial.
Manager at a computer software company with 201-500 employees
With WireGuard, which is locked down over UDP, it is harder for attackers to probe ports.

Setup Cost

Cisco IOS SSL VPN is costly compared to FortiGate and Aruba, though discounts exist and pricing reflects its stability.

Ease and speed of connectivity impress and recommend
I have not found any areas that could be improved so far. I am not sure how Cisco IOS SSL VPN can continue their improvements for the future, but I think it is a great product. To stay on top, they probably need updates to this product. I do not know what kind of improvements these updates are offering. It is a great product so far.
AS
Network operation center engineer at a computer software company with 10,001+ employees
Secure remote access has protected critical data and now simplifies role-based user management
An area for improvement is the pricing model. The concurrent user licenses get expensive pretty quickly as your organization grows, so more flexible pricing options would be a huge plus. Another area is configurational disconnect. While the admin web UI handles about 90% of what you need, the moment you have to do deep, advanced routing customization, you still have to drop back to the command line interface to make those changes. It would be great to see those deeper configurations completely integrated into the web portal. Lastly, it would be awesome to see native support for newer, lighter protocols through WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency.
