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

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Its initial setup was straightforward."
"Technical support is pretty sharp and very responsive."
"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."
"This product is solid, fairly easy to use, and reliable."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"It was a very easy product to install. It can be deployed very fast."
"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."
"I find Fortinet FortiCASB easily customizable."
"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."
"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."
"After creating the policy you can be assured that a user's data is being protected."
"Everything from Microsoft is integrated. You receive regular reports on them all. You can push your reports, logs, and security alerts, which are all integrated. It is crucial that these solutions work natively together to deliver coordinated detection and response across our environment."
"We have become more aware of what services our users are using, how often they are using them, and what data is being sent out of the organization and to which services. So, it is really a lot about visibility and helping us make decisions based on that. It drives some of our policy decisions for adding extra security controls."
"The impact of Microsoft Defender for Cloud Apps on our organization's ability to assess and manage app related risks has been significant because we have more visibility."
"Defender for Cloud Apps has given us good visibility regarding what we've allowed in our environment until now. It helps us to know our inventory, understand what our customers are using, and steer them toward safer practices."
"Microsoft Defender is probably now accepted as the best product on the market for antivirus and web filtering."
 

Cons

"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."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"I appreciate that iboss's single pane of glass console gives centralized visibility into web traffic, user activity, security policies, and alerts from one dashboard, allowing us to quickly investigate incidents and monitor policy violations without switching between multiple tools, improving operational efficiency; however, the dashboard customization and reporting could be more flexible."
"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 is growing so fast that it is often hard for them to keep up with the challenges."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"Sometimes, obviously, there are bugs."
"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can be better."
"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."
"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."
"Licensing cost is a significant concern. With Defender Plan 1, Microsoft Defender for Cloud Apps comes with a pay-per-use model."
"If this solution were more robust then it would be much more useful."
"It is a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."
"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."
"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."
"Defender for Cloud apps is primarily useful for Azure apps. It has limited capabilities for applications based on other cloud platforms."
 

Pricing and Cost Advice

"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."
"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."
"The overall pricing for iboss is very competitive and transparent."
Information not available
"The product's pricing seems fair."
"Where we are right now, this is an acceptable pricing. I would like to see more transparency given to the end user. The end user given to us is via the cloud service provider. There are different programs and license models. Some include this, and some include that. It is all over the place. There can be a little more consistency or simplification in the pricing so that your parts list is not ten pages long, and you are not trying to determine, "If I have an E3, does this cover that?", or "Do I need to pay separately for the license?" Simplification would probably be 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."
"We have an educational licensing agreement. It's a customer agreement for multiple years."
"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."
"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."
"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."
"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."
