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

"I would say iboss is a very good product; its scalability is very good, and it's seamless for the user."
"The security aspect of the solution, particularly the malware behind it, is excellent. That's something that really helped us out. It's not just a simple proxy that just blocks the insights of potential threats that come on behind it. They do malware detection and that helps us a lot."
"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."
"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."
"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 is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"iboss is definitely very good in terms of service."
"I find Fortinet FortiCASB easily customizable."
"The most valuable feature of this solution is its monitoring."
"The solution does not affect a user's workflow."
"It's a full engine that you can use to discover all your assets in the cloud, whether they are on a public cloud or a private cloud."
"I like the alert policies because they are quite robust. It has some built-in templates that we can easily pick up. One of them is the alert for mass downloads, when a particular user is running a massive download on your SharePoint site."
"From what I've seen, it's a good product."
"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."
"In Microsoft Defender for Cloud Apps, there is an option to enable files. Once you enable that, it will give you all the files in your organization and where they are located in the cloud... That feature is very useful for investigation purposes."
"The solution is helping a lot; we get very detailed reporting on security that really shows what users are doing, including what they've opened, what they're sharing, downloading, viewing, and when they are logging in."
 

Cons

"To scale up, a new iboss Node Blade Chassis must be purchased."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."
"File integrity monitoring would be very advantageous as an additional feature."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"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."
"Our iboss subscription access should be more secure with an OTP or VPN etc. It is easy to gain access if, for example, hackers obtain my username and password."
"Its pricing could be better."
"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can be better."
"The response time could be better. It will be helpful if the alerts are even more proactive and we can see more data. Currently, the data is a little bit weak. It is not complete. I can't just see it and completely know which user or which device it is. It takes some effort and time on my part to investigate and isolate a user. It would be great if it is more user-friendly or easy for people to understand."
"Sometimes the support is actually lacking."
"Defender for Cloud apps is primarily useful for Azure apps. It has limited capabilities for applications based on other cloud platforms."
"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."
"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."
"They need to improve the attack surface reduction (ASR) rules."
"There have been instances where the alerts generated have been false positives."
"In the future, I would like to see more plug-and-play capabilities that use AI to tell you what needs to be done. It would be helpful if it scanned our devices and made security suggestions, on a configuration basis."
 

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."
Information not available
"The product's pricing seems fair."
"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."
"It has fair pricing. You pay for what you get. As far as I know, there are no costs in addition to the standard licensing fee."
"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."
"The price could be better and should be reconsidered."
"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."
"We are an MST and we do not pay for the solution. However, the price of the solution could be better."
"The E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."
