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.

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

"The scalability of Pulse Client is good."
"It also provides an auto-connect feature. When you turn on your laptop and put it on auto-connect, it automatically connects."
"Pulse Client is a very good solution; it is very easy to manage, and very stable."
"The most valuable feature of Pulse Client is integration with Google authenticator for two-factor authentication."
"I would recommend this solution to other people."
"The best features OpenVPN Access Server offers is whitelisting members in my company who have joined recently; it is really easy to use, and it is really easy to set up OpenVPN Access Server as an internal app."
"The most valuable features of OpenVPN are its ease of use, client familiarity, end-user familiarity, operating system integration, and price points."
"The product’s adaptability is valuable."
"OpenVPN is a good option for kick-starting any kind of interoperability between offices."
"OpenVPN Access Server provides remote secure access."
"OpenVPN Access Server has positively impacted my organization by helping us design a reliable infrastructure and even providing definite SLA metrics to our clients."
"The features I have found to be most valuable are the levels of encryption I can enact and the compression I can apply to improve throughput."
 

Cons

"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."
"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."
"There are tasks that require logging onto the server to run commands, which is not intuitive through the UI."
"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."
"OpenVPN Access Server needs to have fewer updates."
"It could be faster. It could also be more stable."
"The stability of the solution could improve."
"The solution should provide a faster connection, and its security could be improved."
"When there are too many concurrent users trying to connect at the same time, there may be a bit of a bottleneck."
"It would be nice with all these features, if they could send some examples of each one; just small sample scripts to look at and say, "Oh okay, I could expand on this." That would help us a lot."
 

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."
"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."
"The price point is fantastic since it is free."
"The product offers yearly as well as monthly subscription plans. It has moderate pricing."
"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."
"Open VPN Access Server is open-source and free of charge."
"One of the valuable features of OpenVPN is that it is free for a single user."
"The solution is free of cost."
