When Cisco first took over, it was a bit more difficult to get support, but they now integrate it without differentiating the support for Linksys versus full-blown Cisco switches.

It's not very easy to expand, and it would be beneficial if the process were simpler.

Room For Improvement

OpenVPN Access Server requires user-friendly upgrades, enhanced security, improved compatibility, centralized management, and pricing adjustments for better usability.
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
Adding stronger multi-factor authentication and continuous monitoring using tools like Splunk.
Cloud Engineer at PowerSchool
If they had a one-click setup where you provide credentials instead of manually running commands, that would be beneficial.

If there was a dedicated plan for startups, it would be really helpful.
Devops Engineer at Emergent
 

Setup Cost

Cisco IOS SSL VPN is costly compared to FortiGate and Aruba, though discounts exist and pricing reflects its stability.
OpenVPN Access Server offers cost-effective enterprise pricing with free access, affordable licenses, and straightforward licensing, but paid support.
For more than one hundred users, it costs about $60 per seat.
Technical Services Lead at Telenet Solutions
The sticker price may look clear, but the real cost includes the time spent untangling subscription limitations, account conflicts, sales handoffs, and unclear guidance.
Webmaster & Software Engineer at a university with 501-1,000 employees
My experience with pricing is excellent as the pricing is free.

The experience with pricing, setup cost, and licensing for OpenVPN Access Server is really good, not that expensive.

Valuable Features

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.

The valuable features of Cisco IOS SSL VPN are the ease of use and the speed.
student at a university with 1,001-5,000 employees

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.
Fedir Plotnikov - PeerSpot reviewer
Senior Cloud Infrastructure Engineer at Globant
User management has simplified internal VPN access and now provides clear visibility and control
I do not use any role defining features because it is a really small organization, so it wasn't required, but it is there if needed. I have seen OpenVPN Access Server integrations such as LDAP, RADIUS, PAM, and SAML, but again, due to the size of the company, it wasn't necessary and we didn't have it inside the company. However, it was nice that it is already embedded inside. We haven't used much in terms of integrations with OpenVPN Access Server, so it's hard to say. We only used basic features there. My advice for others looking to implement OpenVPN Access Server is that it is at least worth trying if you need a fast and easy implementation solution without technical overhead and you just need VPN access, which is supported by all operating systems and mobile operating system vendors. It is definitely worth a try. OpenVPN Access Server was purchased directly from the website, not on the AWS marketplace or through a partner purchase. I would rate this product an overall eight out of ten.
