A cloud solution to access the corporate network with BYOD policy

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

"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."

"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."

"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."

"With Tailscale, it is honestly super easy."

"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."

"The best features Tailscale offers are the ease of use and the security it provides for data in transition."

"The most positive impact Tailscale has had on my organization is significant."

"The security is valuable, as there are many providers available, but Tailscale fulfills the requirements that we had, allowing us to access and expose internal apps without exposing them to the general internet."

"Tailscale has positively impacted my organization by making the previously unusable doorbell with the cloud solution fast and reliable for remote access."

"Tailscale is a very solid framework and is very useful for smaller companies if they want to start out or even bigger companies who want to have a robust network of devices that they want to manage."

Cons

"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."

"Pulse Client could improve the system tokens for authentication."

"Another issue is that when I use Tailscale with other alternatives such as Radmin and ZeroTier, it takes high priority and takes all the incoming connections, even if the other alternative has a different IP scope."

"I feel the speed of the control servers are a bit too slow."

"I think Tailscale can be improved by enhancing the free side of things."

"I choose a seven because it sells what it does honestly, but I believe some more flexibility might be needed."

"However, I think improvements could be made in the support for UI clients, especially on Linux machines."

"One somewhat negative point that I see is that if you want to use Exit Node and that is installed on a device within the network, then you have a bit more latency because instead of the packets going from a mobile device to the router at the other home and from the router going out again to the internet, for example, now they have to enter the network, enter the device that has Tailscale, and only then go out."

"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."

"Sometimes you might need to restart your entire system for it to connect."

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."
