Ivanti Secure Access and Zscaler provide secure access to corporate networks, their methods and features may differ. Ivanti Secure Access offers granular control over network access, allowing for on-demand VPN connections when accessing corporate resources. This means users may not need to initiate a VPN connection manually but can access resources seamlessly when accessing corporate websites or applications. This granular feature helps enhance security and user experience by providing secure access only when needed.

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.

Quotes from Members

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

Pros

"Pulse Client is a very good solution; it is very easy to manage, and very stable."
"It also provides an auto-connect feature. When you turn on your laptop and put it on auto-connect, it automatically connects."
"The most valuable feature of Pulse Client is integration with Google authenticator for two-factor authentication."
"The scalability of Pulse Client is good."
"OpenVPN Access Server is a simple and easy-to-use solution that I can use myself without anybody's help."
"OpenVPN Access Server has positively impacted my organization mainly through improved security for myself."
"The core VPN functionality is reliable and relatively easy to administer once it is deployed."
"It allowed people to remotely access files from their mobile devices and was so easy for end-users to use that they were able to work more efficiently no matter where they were, whether at a client’s campus, home, traveling – wherever they had a device and internet access."
"Provides privacy and cryptography for my network communication."
"Overall, OpenVPN Access Server has positively impacted our organization by giving us a highly reliable, stable environment for remote work."
"The product’s adaptability is valuable."
"It is very easy to look at the quality of the connection and the bandwidth and do an investigation if there are problems on the network."
 

Cons

"Pulse Client could improve the reports. The reports are not in PDF and we can't check the details in the reports of users who are using the VPNs."
"Pulse Client could improve the system tokens for authentication."
"Ivanti Secure Access and Zscaler provide secure access to corporate networks, their methods and features may differ."
"It is not scalable."
"The product is fully customized through configuration files, which is all achieved through manual data entry."
"OpenVPN Access Server could be improved in several areas. The encryption strength is inevitably lower compared with the latest technologies, and when I try to add features like two-factor authentication, the needed plugins and so on often are not really available or do not fit well."
"The lack of an official Linux client is a clear gap."
"There could be an easier way to set up the solution."
"I would be more happy with the idea of licensing to have a reduced price with longer, grouped, annual fees. We have a lot of other software that does the same thing. It's a little higher price if you're going with a shorter stint, but there's a reduction in price for three- and five-year contracts."
"Regarding scalability, I find OpenVPN Access Server scalable with some caveats. However, sometimes your license disappears or gets wiped out when you scale the infrastructure, which can be quite annoying and requires reaching out to support to get set up again."
"​There was one annoying feature where we had to disable and enable the user. I cannot remember what it was exactly, but I think it was for a password lockout. It would be nice if there was a checkbox, or something, in the web interface to allow you to unlock a user whose password was locked."
 

Pricing and Cost Advice

"Pulse Client has two types of licenses. One is subsistence-based and the second is perpetual-based. The license cost is good, it is not very costly."
"OpenVPN Access Server is free and open source."
"The product's pricing is good value, definitely. It is one of the best features, I would say. Evaluate the product before seeing which type of licensing is good for you. I think there is a good evaluation method available for OpenVPN, so you can just evaluate if it meets your needs. Then go forward with the right licensing policy."
"Open VPN Access Server is open-source and free of charge."
"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."
"The solution was free of charge."
"Begin with the community version and upgrade to paid one if the need arises."
"OpenVPN is an open-source solution. If the solution is used for personal use it is free. For non-personal use, the solution can be expensive."
"The licensing has a fixed pricing."
