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

"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 were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"iboss is definitely very good in terms of service."
"Deploying iboss leads to good return on investment, estimated around 70% to 80%."
"This product is solid, fairly easy to use, and reliable."
"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."
"I find Fortinet FortiCASB easily customizable."
"Shadow IT discovery is the feature I like the most."
"Threat detection is its key feature, and that's why we use this tool. It gives an alert if a PC is attacked or there is any kind of anomaly, such as there is a spike in sending emails or we see an unauthorized website being accessed. So, it keeps us on our toes. We get to know that there is something wrong, and we can isolate the user and find any issues with it. So, threat detection is very robust in this tool."
"Defender's integration with our identity solutions is critical in our current setup."
"I would rate it a ten because I have not experienced any stability issues so far with Defender for Cloud Apps."
"The most valuable feature is its policy implementation."
"It gives our clients a sense of confidence that in case there are activities on some of their applications, they will get an alert and the issue will be mitigated, based on the action that has been set."
"The general usability of the solution is very straightforward."
"It does a great job of monitoring and maintaining a security baseline. For us, that is a key element. The notifications are pretty good."
 

Cons

"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."
"Sometimes, obviously, there are bugs."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"The dashboards for local use could be better."
"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."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"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."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can be better."
"The integration with macOS operating systems needs to be better."
"Currently, reporting is not very straightforward and it needs to be enhanced. Specific reports are not included and you need to run a query, drill down, and then export it and share it. I would love to have reports with more fine-tuning or granularity, and more predefined reports."
"I would like to see them include more features in the older licenses. There are some features that are not available, such as preventing or analyzing cloud attacks."
"The areas of Microsoft Defender for Cloud Apps that need improvement are related to IAM, as they do not provide much support for local users."
"There could be more granular roles that are out of the box included in the product."
"There are challenges with detection and there are challenges with false-positive rates."
"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."
"We sometimes get errors when we create policies, which is somewhat annoying because some policies stop working due to misconfigurations. We find this challenging because it limits our options for troubleshooting an issue."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"The overall pricing for iboss is very competitive and transparent."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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."
Information not available
"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."
"Microsoft offers bundle discounts and a pay-as-you-go option."
"Its pricing is on the higher side. Its price is definitely very high for a small-scale company. As an enterprise client, we do get benefits from Microsoft. We get a discounted price because of the number of users we have in our company. We have a premier package, and with that, we do get a lot of discounts. There are no additional costs. It only comes in the top-tier packages. Generally, the top-tier license is the best license that you can get for your organization. If you want, you can buy it separately, but that's not a good idea."
"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."
"The product's pricing seems fair."
"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 E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."
"The price could be better and should be reconsidered."
