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

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

"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."

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

"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."

"Its initial setup was straightforward."

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."

"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."

More iboss pros

"I find Fortinet FortiCASB easily customizable."

"It's very easy to install and it includes the Intune portal from Microsoft where I can control all the devices from one place."

"The general usability of the solution is very straightforward."

"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."

"The most valuable feature of this solution is its monitoring."

"The most valuable feature is the alerting system."

"The most valuable feature is its policy implementation."

"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."

"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."

More Microsoft Defender for Cloud Apps pros

Cons

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."

"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."

"The reporting feature needs improvement."

"Its pricing could be better."

"I am currently doing a PoC of the zero trust aspect of it. Compared to other similar solutions, it is hard to get around each feature. It takes a while to get used to it."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

More iboss cons

"The turnaround time to deploy Fortinet FortiCASB could be improved."

"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can be better."

"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."

"There have been instances where the alerts generated have been false positives."

"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."

"The product is very good so far, however, it would be better if it could include more up-to-date threat protection."

"A significant improvement I would like to see is the integration into a single pane of glass, which would allow me to view everything in one place rather than having to switch between different areas."

"Sometimes, we'll get false positive alarms. For example, when a SharePoint path has no file sharing, but there is an external user, it will trigger an alarm that the file has been shared with an external user... the alerting mechanism should be more precise when giving you an alert about what activity has been done with the file..."

"The integration with macOS operating systems needs to be better."

"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."

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."

"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."

"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 not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."

"It is expensive compared to one of its competitors."

Information not available

"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 product's pricing seems fair."

"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."

"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 fair."

"It is a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."

"It has pretty good pricing."
