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

"It was a very easy product to install. It can be deployed very fast."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"The console is cloud-based, which is something I really appreciate."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"Technical support is pretty sharp and very responsive."
"I would say iboss is a very good product; its scalability is very good, and it's seamless for the user."
"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."
"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."
"I find Fortinet FortiCASB easily customizable."
"Microsoft Defender for Cloud Apps is very comprehensive, providing a complete 360-degree view of applications within an organization."
"The most valuable feature is the ease of management; the management is cloud-based and we can work inside or outside on public networks."
"One of the most valuable features is auditing. Some of the other protection services have issues with auditing. Microsoft Defender for Cloud has an excellent auditing technique that helps us avoid the risk of filtering or information loss. You can use different tools to guarantee these things. It allows you to conduct an in-depth exploration of applications, users, and files that are harmful or suspicious. You can also enhance your security setup by creating personalized rules or policies that help you better control traffic in the cloud."
"On-demand scanning is the most valuable feature. In addition, it's a fairly fluid product. It syncs back to the cloud and provides metrics. It's pretty intelligent."
"It is very easy to use, which is what we look for in these types of solutions."
"In summary, we have just begun using this product but so far, it works well and we are satisfied with it."
"It has helped identify areas where we should improve, make changes to improve, the reason why we should make a change, and the impact of making the change."
"There are a lot of features with benefits, including discovery, investigation, and putting controls around things. You can't say that you like the investigation part but not the discovery. Everything is correlated; that's how the tool works."
 

Cons

"The reporting feature needs improvement."
"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."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"File integrity monitoring would be very advantageous as an additional feature."
"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it 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."
"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."
"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can 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 want them to enhance in-session policy."
"MCAS doesn't have many reporting capabilities, and it's really an operational nightmare to get all these things done at this point in time by using MCAS."
"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."
"Microsoft Defender for Cloud Apps' initial setup was quite technical but we were prepared. The time of the implementation depends on the job and how many users are being set up."
"They need to improve the attack surface reduction (ASR) rules. In the latest version, you can implement ASR rules, which are quite useful, but you have to enable those because if they're not enabled, they flag false positives. In the Defender portal, it logs a block for WMI processes and PowerShell. Apparently, it's because ASR rules are not configured. So, you generally have to enable them to exclude, for example, WMI queries or PowerShell because they have a habit of blocking your security scanners. It's a bit weird that they have to be enabled to be configured, and it's not the other way around."
"I would like for it to be available on Mac and for it to support all of the features of Microsoft financing products. It is really for Windows."
"We are having trouble with our continuous reporting configuration and struggling with configuring the collector properly with our log parsing. We've also faced difficulties getting support for this issue. It's taken us months to figure this out after going through a couple of different support channels."
 

Pricing and Cost Advice

"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."
"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 expensive compared to one of its competitors."
"The overall pricing for iboss is very competitive and transparent."
Information not available
"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."
"The pricing is in the middle. It isn't too cheap or expensive compared to other antivirus or security products. It is priced according to industry standards."
"The pricing is a little bit high but right now, we are okay with it because of the compatibility with Office 365, Teams, and Azure AD."
"We have an educational licensing agreement. It's a customer agreement for multiple years."
"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."
"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."
"The product's pricing seems fair."
"The E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."
