Integrates well, highly reliable, but lacking reporting
Pulse Client is used as a client VPN or an SSL VPN The most valuable feature of Pulse Client is integration with Google authenticator for two-factor authentication. 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…

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

"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."
"With Tailscale, I set it up and forget it because it just works, allowing me to avoid worrying about the whole VPN aspect of my home network architecture."
"Tailscale has positively impacted my organization by allowing us to speed up development without worrying about GDPR restrictions."
"Tailscale's best features include the ability to seamlessly integrate and add devices, exit nodes, a very simple UI that is easy to set up, and importantly, access to a CLI so that my agents can set up Tailscale for me."
"I have been using it every day since June 2025, and it has never given me a problem."
"This quick setup with Tailscale has saved me probably days of work that I would have spent learning how to configure traditional VPN solutions, more traditional solutions like WireGuard, where I would have had to learn their entire configuration process and it would have taken days just to set that up."
"Tailscale is a great solution that is fast, easy, and cheap."
"Tailscale has positively impacted my organization with shorter time for setting up connections and improved accessibility."
"The biggest benefit of Tailscale is simplicity; it is quick to set up and provides a stable and secure connection."
 

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."
"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."
"I choose a seven because it sells what it does honestly, but I believe some more flexibility might be needed."
"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."
"However, I think improvements could be made in the support for UI clients, especially on Linux machines."
"I think Tailscale can be improved by enhancing the free side of things."
"I initially got introduced to Tailscale in high school when I needed access to services running on my server, but due to deep packet inspection being in place, I could not use Tailscale."
"Regarding how Tailscale can be improved, I think for free users, there are some limited options."
"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."
 

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."
