Enhances web security with a single pane of glass and flexible deployment
I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

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.

Deployment has been seamless with insightful data categorization and enhanced control
The features of Microsoft Defender for Cloud Apps that I have found most valuable include the overall portal view, with bubble graphs which give us insight into what goes where in the categorization, nowadays with Generative AI but all kinds of categorization, collaboration, etc. That central view of the portal is very useful for us. 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. Therefore, we can add more control, and we have already done so. This was not possible in the old solution, in the old CASB solution with Netskope. We now can see on the spot, and we do that almost weekly, what the end users are utilizing, which cloud providers or cloud apps they're using. The visibility into OAuth apps provided by Microsoft Defender for Cloud Apps is very good. The visibility into risk and risk management of our organization's Generative AI apps is very nice, as you can choose the category Generative AI and then see exactly what traffic has been going to and from Generative AI in the cloud. This makes us very insightful on what is used within the company. We have some policies on blocking specific Generative AI, and we use within our company one particular AI part, which is CoPilot of Microsoft. In this way, we can see what the end users are using other than CoPilot, and that makes us more in control. The effectiveness of the integration of Microsoft Defender for Cloud Apps with Defender XDR and defending against SaaS attacks is very intuitive. It works immediately if we create a new policy or in Purview or in Microsoft Defender for Cloud Apps, or when we make an app unsanctioned by blocking it, then it is almost immediately, or at least within a couple of hours, effective on all the endpoints where the EDR is running. This gives us much better control over things than before.

Quotes from Members

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

Pros

"Its initial setup was straightforward."
"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."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Technical support is pretty sharp and very responsive."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"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."
"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."
"I find Fortinet FortiCASB easily customizable."
"I find Fortinet FortiCASB easily customizable."
"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."
"The most valuable feature is its policy implementation."
"The most valuable feature is the seamless integration across different clouds."
"Better logging allows us to find problems and take appropriate steps to lock them out."
"The integration within the entire Defender suite is highly valuable because it allows for communication between different components and offers pretty decent correlations."
"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."
"Microsoft Defender for Cloud Apps is very comprehensive, providing a complete 360-degree view of applications within an organization."
 

Cons

"The reporting feature needs improvement."
"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."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"File integrity monitoring would be very advantageous as an additional feature."
"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."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Sometimes, obviously, there are bugs."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can be better."
"The turnaround time to deploy Fortinet FortiCASB could be improved."
"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."
"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."
"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."
"They should continue integration with all other Microsoft security-related products. The integration with all the other products is still ongoing."
"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."
"I believe it's only set to be integrated with Microsoft Defender for identity and identity protection. I would like to see it available for use with something like Office 365 Defender. I don't think it's integrated with that yet."
"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."
"I would prefer to have filtering options incorporated within the policies, enabling the solution to perform tasks beyond mere blocking or allowing."
 

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."
"It is expensive compared to one of its competitors."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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 probably in line with other solutions, but I do not deal with the financial side."
"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."
Information not available
"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."
"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 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."
"The E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."
"We have an educational licensing agreement. It's a customer agreement for multiple years."
"We are an MST and we do not pay for the solution. However, the price of the solution could be better."
