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.

Zero-trust access has improved our secure VPN connectivity and protected internet usage
If I could change or improve anything about Appgate SDP, it would be to enhance the user experience by improving the UI so that it is more explanatory. Currently, the UI feels as though it is doing something behind the scenes, and at first sight, nobody can understand what this application is for. I think that is the main thing regarding needed improvements.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"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."
"Technical support is pretty sharp and very responsive."
"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."
"Our primary use case for this product is DLP,"
"The iboss solution gives me the ability to scan the traffic through all the ports, through all the 131,000 PCP and UDP ports, and with this ability, we have the granularity also for consults over social media and applications on mobile, and this is an advantage that the customers are looking for right now."
"The console is cloud-based, which is something I really appreciate."
"The flexibility of the tool is valuable; it is very robust, has a very robust configuration capability, is pretty well documented, and is also good interface-wise."
"Appgate SDP is the best solution for micro-segmentation and supplying VPN solutions."
"One of the most important features is stopping lateral movement across our network."
"It is pretty stable."
"The interface is really friendly. It's simple to understand."
"Appgate SDP has positively impacted my organization, as we are using it to securely access the internet after the cyber attack."
"It is a scalable solution...The support answers your questions very fast."
"The simplicity of the SDP platform is a standout feature; instead of navigating through intricate details, users can seamlessly connect to the company's network or switch to the internet with minimal effort."
"The cloud proxy and integration are some of the key features. Since there is cloud waste, we can quickly provision it and start working on the configuration. On top of that, they have added a few more features. They have integrated CASB, and file sandboxing is part of it."
"Since this is a cloud based product, we don't have to bother about the hardware or physical status and space."
"In summary, this is a good product and I completely recommend it."
"Zscaler Web Security protects our users in remote locations from internet threats - even if they are not connected to our network."
"The solution's most valuable features are its reliability and availability, measured by the number of ports it offers."
"The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights."
"The product's initial setup phase is a bit easy, as one doesn't need high technical expertise."
"There is no lag in service when accessing the internet."
 

Cons

"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."
"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."
"iboss can be improved because the integration could be better; you need to import all the sites that you access today, and there are a few problems whenever you import thousands of websites, making the integration process messy for the users."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"The dashboards for local use could be better."
"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."
"File integrity monitoring would be very advantageous as an additional feature."
"On the cloud, when you make some changes, it may be difficult."
"They could provide a single-box solution to manage tools for 4000 users. Additionally, they could add extra features to enhance remote micro connection."
"One thing that kind of sticks out to me is the ability to do a proper non-split tunnel. VPN tunnel-wise, it is not really a true unsplit tunnel, but I think that's just because of the way it's designed. A split VPN basically allows your system to talk to other systems without being forced down the tunnel. A VPN running in a non-split tunnel mode forces all the traffic down the tunnel to wherever you're VPNing to. It forces the traffic down so that the traffic is subject to the firewall and rules that you have in your corporate environment and such. It helps to prevent remote malicious folks that may be talking directly to that box from piggybacking into the corporate environment through it. They do it partially, but it would be nice to see more of an enterprise-level solution there."
"On the cloud, when you make some changes, it may be difficult."
"It would be better to connect to an application portal from any device. Documentation and support could be better."
"One thing that kind of sticks out to me is the ability to do a proper non-split tunnel."
"One limitation is that it's harder to provide access to multiple applications in the company with Appgate, but that's probably because of poor management."
"The user interface should be improved as it is not very easy to work with the updates."
"They could provide more time for the onboarding the training of an IT person."
"In terms of user experience, it could be better."
"We'd like for them to include some sort of antivirus tool."
"Zscale is providing a proxy IP, and most government sites will block traffic from a proxy. Also, we see some performance issues on the cloud side during DC failover."
"Zscaler Internet Access can improve by having more option for filtering policy which is currently only ip based (location policy)."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"Zscaler Internet Access can improve by adding traffic filtering based on the DNS."
"Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers."
 

Pricing and Cost Advice

"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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."
"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 not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."
"The overall pricing for iboss is very competitive and transparent."
"It is a pretty expensive tool. It is maybe about $20,000 per year for a hundred users or so."
"The pricing is according to the market price. It is not a very cheap solution. They have some very aggressive promotions to sell the product in the market."
"We pay $100 per user per month. One license for the site is around $17."
"Our monthly fee is around R3000."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"The tool is moderately priced."
