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

"It also provides an auto-connect feature. When you turn on your laptop and put it on auto-connect, it automatically connects."
"The scalability of Pulse Client is good."
"The most valuable feature of Pulse Client is integration with Google authenticator for two-factor authentication."
"Pulse Client is a very good solution; it is very easy to manage, and very stable."
"OpenVPN Access Server has positively impacted my organization by allowing access to our private services, enhancing security, and enabling remote work from anywhere, as I just need to connect to the VPN to have encrypted traffic to our private resources."
"For us, it's important that OpenVPN Access Server is cheap and that we get to use it ourselves."
"The stability is very reliable in my experience."
"OpenVPN is a good option for kick-starting any kind of interoperability between offices."
"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."
"A valuable feature for us is its ability to see the new Citrix server as a local server within the company. And it allows us to test abroad."
"Overall, my best feature of OpenVPN Access Server is the user management, which is very nice because OpenVPN can be quite painful and not very visible."
"We use OpenVPN Access Server to connect from site to site from our data center to our customer site and to dial and access our VPN to our network."
 

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."
"My impression of the connection speed using OpenVPN Access Server is that, compared to other VPN solutions, OpenVPN Access Server is a little bit slow, but it is very safe and always connects."
"Everything in OpenVPN Access Server is very good, but the price is expensive."
"OpenVPN Access Server needs to have fewer updates."
"I think OpenVPN Access Server's setup can be just one click; currently, it takes multiple steps, and when you forget the admin password, you are locked in."
"There could be an easier way to set up the solution."
"The connections could be faster and more stable."
"I would like to see continued advanced security implementation."
"I want the tool to be faster. We have experienced connectivity issues while using OpenVPN and FortiClient."
 

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 offers yearly as well as monthly subscription plans. It has moderate pricing."
"The solution is free of cost."
"The licensing has a fixed pricing."
"Begin with the community version and upgrade to paid one if the need arises."
"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."
"The Pro Edition has a reasonable price per user."
"It is an open-source solution, so we don't pay for anything."
"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."
