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.

Seamlessly customize security features but need improved deployment speed
I find Fortinet FortiCASB easily customizable. It allows me to leverage features that cover almost eighty percent of use cases required by my clients. The compliance management feature supports GDPR and HIPAA compliance, effectively meeting those use cases. The hybrid model of Fortinet offers seamless deployment on cloud or hybrid best suited for customers, making it adaptable in various scenarios.

Integration with existing cloud workflows has simplified compliance and threat detection
Licensing cost is a significant concern. With Defender Plan 1, Microsoft Defender for Cloud Apps comes with a pay-per-use model. Each feature has its own pricing when activated on VMs. For example, the vulnerability assessment has separate pricing, the base model including encryptions has separate pricing, and the compliance features have separate pricing. This applies to each VM and Azure resource individually. It is not straightforward where you can take one license and apply it to everything. Each feature has its own pricing model which can be tedious, as the costs keep accumulating. The only lacking feature currently is XDR (extended detection and response). Apart from that, I have only positive experiences with the whole Microsoft suite, except for the pricing structure.

Quotes from Members

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

Pros

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"The console is cloud-based, which is something I really appreciate."
"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 security aspect of the solution, particularly the malware behind it, is excellent."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"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."
"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."
"Its initial setup was straightforward."
"I find Fortinet FortiCASB easily customizable."
"The raw logs that come directly from Microsoft Defender for Cloud Apps contain all the data I need, and the ability to track activities happening on cloud applications and the alerts provided is an interesting aspect."
"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."
"The major benefit is that it is a Microsoft tool, so if you're in a Microsoft ecosystem, this is the best tool that you can get in the market."
"In summary, we have just begun using this product but so far, it works well and we are satisfied with it."
"The ability to prevent users from using certain applications is one of the most valuable features. It doesn't require any configuration for implementation from the client perspective. It just works right away and gives you the information you need."
"The discovery function and the discovery catalog are really valuable, and the ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, enhances the organization by helping to manage and control cloud app usage effectively."
"The most valuable feature is the ease of management. It's important."
"The compliance capabilities of Microsoft Defender for Cloud Apps are quite extensive."
 

Cons

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"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."
"The endpoint-type solution is an area that needs some improvement."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"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, and that is where in 2025 we had to migrate to the Palo Alto-based platform."
"File integrity monitoring would be very advantageous as an additional feature."
"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."
"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."
"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can be better."
"The documentation could be improved as it is not updated immediately when Microsoft makes changes. Users must wait a few weeks for the changes to be reflected in the documentation."
"The insights could be improved, especially in reporting. While it is possible for me to see the usage from different cloud apps, determining if critical data has been uploaded or if it is just normal transport data is difficult."
"There are some features, such as user navigation content filtering, that are disabled by default, and it probably makes sense to enable them by default."
"Defender for Cloud Apps could come with more configured policies out of the box. Also, integration could be easier. Integration is moderately difficult because Microsoft hasn't developed a solution that unifies device onboarding and management. You have to use Intune to manage devices and Defender for Endpoint to enforce policies. They need to fix their integration, but I believe they will straighten it out by the end of the year."
"However, the price of the solution could be better."
"It takes some time to scan and apply the policies when there is some sensitive information. After it applies the policies, it works, but there is a delay. This is something for which we are working with Microsoft."
"I would like more customization of notifications. Currently, you either get everything or you get limited information. I would like to have something in between where we can customize the data that is included in notifications."
"An area of Microsoft Defender for Cloud Apps that needs to be improved or enhanced is the reporting function. In the beginning, there was a good reporting function which gave us a sort of monthly overview report. But that has gone away."
 

Pricing and Cost Advice

"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."
"The overall pricing for iboss is very competitive and transparent."
"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."
"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."
Information not available
"The cost could be improved when you need to pay for anything. For example, refreshing files takes time to load, though it may be my Internet. To improve the refresh time, Microsoft says that we need to pay for a Premium license, and I don't like paying for things that help make a solution better."
"This product is not expensive."
"We are an MST and we do not pay for the solution. However, the price of the solution could be better."
"It is a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."
"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."
"The pricing is fair."
"We have an educational licensing agreement. It's a customer agreement for multiple years."
"It has pretty good pricing."
