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.

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.

Zero trust access has transformed remote connectivity and now simplifies secure app usage

Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, is very strong, though there are a few areas where improvements can be made. One challenge observed is around initial troubleshooting and visibility. While Zscaler Private Access provides logs, it can sometimes take time to pinpoint the exact cause of access issues, especially in complex environments with multiple policies and identity integration. Another area is the dependency on identity and connector health. Since Zscaler Private Access is heavily reliant on app connectors and identity providers, any issues with these components can impact user access, making proper monitoring critical. During the initial setup, policy configuration and application onboarding require careful planning, especially for larger environments with many applications. These challenges are manageable with proper design and monitoring. Overall, the platform delivers strong security and user experience. I would recommend a few improvements, especially around user interface, reporting, and troubleshooting experience. From a user interface perspective, while the platform is powerful, the policy configuration and navigation can feel complex, especially for new users. A more simplified and intuitive layout for policy mapping and application access would help reduce the learning curve. In terms of reporting, Zscaler Private Access provides logs, but having more built-in customizable dashboards and analytics would be very helpful. Better visibility into user access patterns, application performance, and real-time troubleshooting insights would improve operational efficiency. From a support and troubleshooting standpoint, it would be beneficial to have more granular centralized visibility, allowing for quick end-to-end tracing of a user request from authentication to application access without switching between multiple views. These improvements would make the platform even more efficient, especially for large-scale enterprise environments.

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."

"This product is solid, fairly easy to use, and reliable."

"It was a very easy product to install. It can be deployed very fast."

"Our primary use case for this product is DLP,"

"The console is cloud-based, which is something I really appreciate."

"The iboss solution gives me the ability to scan the traffic through all the ports, through all the 131,000 PCP and UDP ports, and with this ability, we have the granularity also for consults over social media and applications on mobile, and this is an advantage that the customers are looking for right now."

"Technical support is pretty sharp and very responsive."

"Content filtering is the most useful feature of iboss."

More iboss pros

"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."

"The raw logs that come directly from Microsoft Defender for Cloud Apps contain all the data I need, and the ability to track activities happening on cloud applications and the alerts provided is an interesting aspect."

"The most valuable feature is the alerting system."

"The solution does not affect a user's workflow."

"The most valuable features of Microsoft Defender for Cloud Apps include live, up-to-date information, which provided real-time alerts, and the ability to delve into detailed metadata information."

"The most valuable feature is the ease of management; the management is cloud-based and we can work inside or outside on public networks."

"Defender for Cloud Apps has given us good visibility regarding what we've allowed into our environment until now."

"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."

More Microsoft Defender for Cloud Apps pros

"It does the job. What it is needed for. I can use it for VPN, I can use it for secure connections, I can use it as a firewall. So the solution does the job."

"It is a stable solution."

"The customer service and support are very good."

"The ZPA is a unique feature which offers VPN along with all the additional security needed."

"Has a good zero trust feature."

"Overall, the solution does a pretty good job at web filtering."

"This is a very good and stable solution that has all the requirements for your security solutions."

"The user interface of Zscaler Private Access is excellent. With proper knowledge and expertise, one can efficiently handle intricate enterprise environments without feeling overwhelmed. This leads to exceptional productivity for managed service providers. The user experience is remarkably streamlined, enabling the management of even the most complex enterprise setups without any excessive complications."

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."

"File integrity monitoring would be very advantageous as an additional feature."

"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."

"SSL decryption: We had issues with learners using apps instead of using web browsers."

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

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

More iboss cons

"They need to improve the attack surface reduction (ASR) rules."

"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."

"Sometimes, there is a delay when it comes to getting an alert policy email; sometimes it takes two or three hours for that email to be sent."

"I would prefer to have filtering options incorporated within the policies, enabling the solution to perform tasks beyond mere blocking or allowing."

"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."

"It doesn't actually decrease the time to respond. This has been an issue with Microsoft recently. Sometimes, there is a delay when it comes to getting an alert policy email... Sometimes it takes two or three hours for that email to be sent."

"I want them to enhance in-session policy."

"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."

More Microsoft Defender for Cloud Apps cons

"The solution's granularity should be improved because it has limited granular options to control, visible, allow, block, delay, and receive."

"Sometimes, support takes time since the solution has some bugs that need fixing."

"The pre-defined dictionaries could be improved."

"There aren't really any missing features that I have witnessed."

"The pricing for Private Access seems to be on the expensive side, and I believe they should consider making it more competitive with other solutions."

"The interface needs a bit of work."

"It has a limitation, if you are creating a rule or something for a web application or something, you could only add five users, not more than that. Five or four users are only included in a rule. If you want to create a rule for more than five or four users, you have to go through other methods, not particularly with the application. Working within the application with this method would be quite easy as compared to listing a URL or a normal IP address."

"It needs to offer SSO, single sign-on, and items of that nature."

Pricing and Cost Advice

"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."

"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."

"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."

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

"This product is not expensive."

"We have an educational licensing agreement. It's a customer agreement for multiple years."

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

"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."

"The E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."

"The pricing is fair."

"The product's pricing seems fair."

"The price could be better and should be reconsidered."

More Microsoft Defender for Cloud Apps pricing and cost advice

"It's an affordable solution"

"The price is competitive."

"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."

"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."

"Pricing for Zscaler Private Access is moderate. It's acceptable, though I can't give you the exact price currently. It's not too expensive, and on a scale of one to five, I would rate it a four out of five in terms of pricing."

"It's expensive currently. But when purchasing for a large number of users, there's room to negotiate. It's really up to the procurement team."

"The product is a little more expensive than other tools."

"Zscaler SASE software is quite expensive compared to other solutions"
