Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

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 solution has massively improved our security posture, giving us full visibility into what our staff does online."
"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."
"This product is solid, fairly easy to use, and reliable."
"iboss has significantly lowered the number of security incidents. It is crazy how much it blocks and how much it is aware of the outside danger."
"iboss is definitely very good in terms of service."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"It was a very easy product to install. It can be deployed very fast."
"Technical support is pretty sharp and very responsive."
"The best features Tailscale offers are the ease of use and the security it provides for data in transition."
"In terms of how Tailscale has impacted my organization positively, it is good for security on the network side of things and helps us connect properly, so because our company is remote globally, even if someone is in Australia and needs to connect to a cluster or any services, instead of routing through the public internet and exposing the traffic there, we can connect internally through Tailscale tailnets and everybody is working."
"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."
"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 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."
"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."
"There is no better option than this."
"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."
"Zscaler B2B provides significant security benefits by reducing attack surfaces through Zero Trust Network Access (ZTNA) implementation."
 

Cons

"Sometimes, obviously, there are bugs."
"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"File integrity monitoring would be very advantageous as an additional feature."
"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."
"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."
"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."
"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."
"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."
"I feel the speed of the control servers are a bit too slow."
"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."
"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 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 would not say anything in Tailscale's use case could be improved; what it does and its intended use is perfect, but the application on the laptop is a little buggy since it continuously opens in the background when it should not be."
"Regarding how Tailscale can be improved, I think for free users, there are some limited options."
"Sometimes trying to log out of a particular tailnet and connecting to the company's Tailscale tailnet is challenging."
"Some areas for improvement include the SSL inspection, as decrypting and inspecting encrypted traffic induces latency."
 

Pricing and Cost Advice

"It is not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."
"We had the cost of purchasing a new appliance along with the implementation and licensing costs. However, the following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs."
"It is probably in line with other solutions, but I do not deal with the financial side."
"It is expensive compared to one of its competitors."
"The overall pricing for iboss is very competitive and transparent."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
