Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.7
Cisco IOS SSL VPN offers strong security with high ROI, easy installation, minimal resource impact, and positive user feedback.
Sentiment score
2.1
OpenVPN Access Server Enterprise efficiently connects employees, balancing initial costs with intellectual value, and provides essential connectivity benefits.
 

Customer Service

Sentiment score
7.7
Cisco IOS SSL VPN is praised for its responsive, skilled customer support and clear documentation, reducing direct contact needs.
Sentiment score
3.6
OpenVPN Access Server Enterprise technical support is highly rated, with responsive service and comprehensive documentation aiding user problem-solving.
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.
We contact support regularly, especially for deployments, and they are very responsive.
It was very good, and I would rate it an eight.
I have not dealt with support or customer service, however, the documentation is good, and I would rate it a seven out of ten.
 

Scalability Issues

Sentiment score
7.8
Cisco IOS SSL VPN is scalable and integrates well with Cisco's ecosystem but may need improvements in pricing and licensing.
Sentiment score
5.5
OpenVPN Access Server is scalable yet faces challenges like international expansion, downtime, and client ease-of-expansion processes.
It integrates well with Cisco's ecosystem, providing flexibility and options to connect to diverse environments.
It's not very easy to expand, and it would be beneficial if the process were simpler.
I would give OpenVPN a six out of ten for scalability, as it's usually a single user or single device.
 

Stability Issues

Sentiment score
8.0
Cisco IOS SSL VPN is highly rated for stability but can experience intermittent issues and requires frequent updates.
Sentiment score
4.1
OpenVPN Access Server Enterprise is stable and reliable, with minor issues during Windows 10 updates resolved by patches.
Linksys can be fairly stable for easy environments, but in more complex network environments, Cisco is definitely a lot more stable.
 

Room For Improvement

Cisco IOS SSL VPN needs better integration, usability, compatibility, language support, and simplified licensing to enhance user experience.
OpenVPN Access Server Enterprise needs improved usability, stability, security, and features like Active Directory support and centralized management.
There have been issues with operating systems where newer updates cause problems with backward compatibility.
I believe Cisco could support easier configuration and having tools that allow for easier management and configuration.
It doesn't matter if it's Windows, Apple, Mac, or Linux - they're all very easy.
OpenVPN could improve in centralized management.
 

Setup Cost

Cisco IOS SSL VPN is expensive but valued by enterprises; pricing is $60 per seat for over 100 users.
OpenVPN Access Server Enterprise offers transparent pricing, affordable plans, and exceptional value, making it cheaper than Microsoft and Cisco.
For more than one hundred users, it costs about $60 per seat.
My experience with pricing is excellent as the pricing is free.
 

Valuable Features

Cisco IOS SSL VPN offers strong encryption, reliable connectivity, seamless integration, multi-factor authentication, and practical management for secure remote access.
OpenVPN Access Server Enterprise offers easy setup, strong security, compatibility, affordability, and seamless integration with multiple operating systems.
The solution is also very scalable, offering up to one hundred licenses for free, and can integrate well with Cisco's ecosystem, such as Cisco ISE and NAC.
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.
The most valuable features of OpenVPN are its ease of use, client familiarity, end-user familiarity, operating system integration, and price points.
What I appreciate the most about OpenVPN Access Server is that it's very easy to set up.

Featured Reviews

Rupesh Kolhapurkar - PeerSpot reviewer
Offers easy setup phase but needs to improve connectivity
For our company's remote workforce connectivity, the tool was very useful during the COVID-19 situation. In general, the VPN functionality offered by the product was very useful during the COVID-19 situation. In terms of the product's ability to secure third-party access, the tool works very well. The most valuable feature of the product in terms of network security stems from the fact that the tool provides access to the whole network, and even if users give access to some special applications, it is still really helpful. The clientless access feature is not available for clients. My company installed the product for its clients. If the product offers a clientless access feature, then it is okay and can be very helpful for our company. I recommend the product to those who plan to use it. Cisco IOS SSL VPN is a reliable product. The product is very helpful for a work-from-home setup as the tool can be used to access our company's internal network, which Falls outside the network of our organization. I rate the tool a seven to eight out of ten.
