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 strengthened remote connectivity and secures diverse office devices
Appgate SDP support is always available to assist, which is the primary strength. However, there are areas for improvement. When a user is unable to connect, the platform should display detailed information such as the user's IP address, MAC address, and specific reasons for connection failure. Currently, aside from invalid username and password errors, Appgate SDP provides generic errors related to policy, such as a policy admin error. The system should provide deeper diagnostics to explain why a user cannot connect. The dashboard could also be enhanced with additional features and logins to provide better visibility. Sometimes there is no immediate clarity about what is happening. After using Appgate SDP for a long time and experiencing various errors, we have learned where to investigate, but this would be problematic for new users trying to resolve issues. The dashboard could display user connection times, failure reasons, and other relevant information. The user activity logs and accounting features should be improved in particular.

Secure remote access has protected critical data and now simplifies role-based user management
An area for improvement is the pricing model. The concurrent user licenses get expensive pretty quickly as your organization grows, so more flexible pricing options would be a huge plus. Another area is configurational disconnect. While the admin web UI handles about 90% of what you need, the moment you have to do deep, advanced routing customization, you still have to drop back to the command line interface to make those changes. It would be great to see those deeper configurations completely integrated into the web portal. Lastly, it would be awesome to see native support for newer, lighter protocols through WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency.

Quotes from Members

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

Pros

"Deploying iboss leads to good return on investment, estimated around 70% to 80%."
"iboss is easy to use despite its complexity. Multiple engineers manage it, but it's significantly more straightforward to administer than traditional VPNs and web proxies."
"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"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."
"It was a very easy product to install. It can be deployed very fast."
"Our primary use case for this product is DLP,"
"It is a scalable solution...The support answers your questions very fast."
"Appgate SDP has positively impacted my organization, as we are using it to securely access the internet after the cyber attack."
"The interface is really friendly. It's simple to understand."
"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 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."
"It is pretty stable."
"One of the most important features is stopping lateral movement across our network."
"It allows our employees to work remotely across Mac, Windows, and Linux platforms."
"OpenVPN Access Server has positively impacted my organization mainly through improved security for myself."
"The most valuable features of OpenVPN are its ease of use, client familiarity, end-user familiarity, operating system integration, and price points."
"OpenVPN is a good option for kick-starting any kind of interoperability between offices."
"Overall, my best feature of OpenVPN Access Server is the user management, which is very nice because OpenVPN can be quite painful and not very visible."
"The stability is very reliable in my experience."
"We were surprised how straightforward it was to integrate with AWS."
"The solution is secure and user-friendly."
 

Cons

"The dashboards for local use could be better."
"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."
"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."
"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."
"File integrity monitoring would be very advantageous as an additional feature."
"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."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"They could provide a single-box solution to manage tools for 4000 users. Additionally, they could add extra features to enhance remote micro connection."
"It would be better to connect to an application portal from any device. Documentation and support could be better."
"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."
"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."
"One thing that kind of sticks out to me is the ability to do a proper non-split tunnel."
"On the cloud, when you make some changes, it may be difficult."
"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."
"OpenVPN Access Server could be improved in several areas. The encryption strength is inevitably lower compared with the latest technologies, and when I try to add features like two-factor authentication, the needed plugins and so on often are not really available or do not fit well."
"There sometimes is an incompatibility between some VPNs."
"There are certain shortcomings in the product's stability that need improvement."
"OpenVPN Access Server can be improved by addressing the issue we faced with a single VPN server since it does not allow the creation of replicas without a load balancer, which we found to be an availability issue that could be easily fixed."
"The logs should be made easier to read."
"The connection speed utilizing OpenVPN Access Server is notably slow, with high latency affecting performance."
"We occasionally have internet issues which affect stability."
"The lack of an official Linux client is a clear gap."
 

Pricing and Cost Advice

"It is expensive compared to one of its competitors."
"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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"The overall pricing for iboss is very competitive and transparent."
"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."
"It is a pretty expensive tool. It is maybe about $20,000 per year for a hundred users or so."
"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."
"Begin with the community version and upgrade to paid one if the need arises."
"OpenVPN Access Server is free and open source."
"At one point I had to purchase addition connection licenses. I was very pleased with the pricing and licensing; so much easier than navigating the confusing jungle of Microsoft and Cisco licensing and pricing. That alone made the product a delight to manage."
"The licensing has a fixed pricing."
"OpenVPN is a free and open-source solution."
"One of the valuable features of OpenVPN is that it is free for a single user."
"It is an open-source solution, so we don't pay for anything."
