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 access has simplified hybrid connectivity and has unified multi-cluster workflows
I would say that in terms of Tailscale, if I have so many tailnets I need to connect to, there are some issues in the login process that need a little bit of attention from the Tailscale team. Sometimes, you would probably need to restart your entire system for it to connect. As a DevOps as a Service engineer, I have so many clients that are using Tailscale, and I would need to connect to maybe five different tailnets because they are different clients. Client A might have a Tailscale, Client B, Client C, and so on. When changing between tailnets, sometimes it hangs. Sometimes you might need to restart your entire system. This is a bit of a headache in that aspect. However, I believe if you are just using a particular tailnet, just one, then it is quite easy and there won't be any headache. For me, I think it can be improved in the aspect of having multiple tailnets to connect to. A good refresh on the Tailscale side and the backend side to refresh the connection anytime there is a new connection to be made would be helpful. Instead of needing to restart the system, it should be able to refresh itself. The connection side and connecting to multiple Tailscale instances can be problematic, and sometimes you have to restart your system when switching between them. The ACL sometimes is like another language on its own entirely. It is fine, but they need to make it in a YAML format instead of the current format because it is quite new and something you have to go and study. If they can make it like a YAML format, that would be better. Aside from the switching which I mentioned and the fact that you have to relearn their ACL, if the ACL could be in a YAML format instead of JSON format, that would be beneficial. I don't think there is much they can do about the switching of tailnets, but if they can have a YAML format of the ACL, that would be good. Every other thing is a ten out of ten. The connection-wise is easy to set up and easy to install. It is good to have things connected all together from on-premises, from so many environments, and even exit nodes as well. It is good overall. The pricing, I think Tailscale can be a little bit on the higher side. It is not for teams with just small users. If you want to set it up for small users and a small startup, I don't think you can afford it and might need to go to other open-source alternatives. It is good for teams that have maybe fifty plus users or one hundred users. In terms of pricing, I would say it is on the higher side, but it is worth it. The price is worth the functionality. As a user, I would say it is more on the higher side, but based on its functionality, it is worth the price.

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."
"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."
"Tailscale has positively impacted my organization and consulting work by making remote connections easy, significantly reducing the friction and making this very reliable, even behind difficult networks with CGNAT or other situations that make establishing connections difficult using other means."
"Tailscale has really helped in terms of security because users can be in another part of the world and, instead of them connecting to the company environment through the local network there, they can switch on their Tailscale and once they switch on their Tailscale, they don't have to connect over their internet; they just go through Tailscale to access company infrastructures."
"Tailscale has positively impacted my organization by allowing us to speed up development without worrying about GDPR restrictions."
"Tailscale has been helping my organization a lot, primarily for security, as I do not have to open up any port in my router, which is really helpful."
"I have been using it every day since June 2025, and it has never given me a problem."
"For my organization, we use Tailscale for our database as a secure way to access our VPC, and it is an easy, lightweight, and very useful way for everyone to connect and disconnect with a very nice UI."
"Tailscale has positively impacted my organization with shorter time for setting up connections and improved accessibility."
"Tailscale is very intuitive as well as accessible, which allowed us to connect everything to our testing network very seamlessly since it could easily be downloaded onto mobile devices or other devices."
 

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."
"I am currently facing an issue where on my Mac, Tailscale does not allow me to log in to multiple accounts."
"I feel the speed of the control servers are a bit too slow."
"Tailscale could be improved with more advanced network visibility and monitoring tools, cleaner pricing tiers for scaling teams, and enhanced built-in reporting for device posture and controls for enterprise environments."
"I choose a seven because it sells what it does honestly, but I believe some more flexibility might be needed."
"One thing I want Tailscale to improve is their user interface for Arch Linux, which is one of the devices I have that I installed Tailscale on, but they do not have the native package with full features, a capability I really want them to develop."
"Sometimes you might need to restart your entire system for it to connect."
"I am currently testing the ability to expose to the WAN certain services that we select, which is in beta. I imagine it is still in development, but from the tests we have done, the connection outward is quite slow, which is a point of curiosity, and I hope that aspect can be improved."
"I think Tailscale can be improved by enhancing the free side of things."
 

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."
