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.

"Pulse Client is a very good solution; it is very easy to manage, and very stable."
"We use the solution to access remote services."
"OpenVPN is a good option for kick-starting any kind of interoperability between offices."
"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

"Ivanti Secure Access and Zscaler provide secure access to corporate networks, their methods and features may differ."
"Pulse Client could improve the system tokens for authentication."

Pricing and Cost Advice

"One of the valuable features of OpenVPN is that it is free for a single user."
"It is an open-source solution, so we don't pay for anything."
"The licensing has a fixed pricing."
