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.

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

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

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

"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."

"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."

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

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

"The security aspect of the solution, particularly the malware behind it, is excellent."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

More iboss pros

"In summary, we have just begun using this product but so far, it works well and we are satisfied with it."

"After creating the policy you can be assured that a user's data is being protected."

"Better logging allows us to find problems and take appropriate steps to lock them out."

"The discovery function and the discovery catalog are really valuable, and the ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, enhances the organization by helping to manage and control cloud app usage effectively."

"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."

"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 of this solution is its monitoring."

"All of the features are valuable because all of the features are related."

More Microsoft Defender for Cloud Apps pros

"Users get direct secure access to applications over the internet."

"The most valuable features of Zscaler CASB are API integration and DLP."

"The product provides a seamless user experience."

"The product's most valuable features are cloud-based services and secure internet access. We don't have to set up any physical appliances."

"SASE's most valuable features are proxy and content filtering."

"The scalability is pretty good."

"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."

"The scalability by definition is kind of intrinsically built-in."

Cons

"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."

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

"The reporting feature needs improvement."

"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."

"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."

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

"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."

More iboss cons

"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."

"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."

"If you have more elaborate needs or if you have some more sophisticated use cases, for example, if you need an in-line component, or if you need to distinguish between sanctioned and unsanctioned applications, this solution doesn't cut it."

"We've had an issue where an in-session policy was not working."

"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."

"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."

"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."

"There are some features, such as user navigation content filtering, that are disabled by default, and it probably makes sense to enable them by default."

More Microsoft Defender for Cloud Apps cons

"There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors."

"An area for improvement would be the ease of configuration."

"The product must allow users to check logs for an entire year in the local console."

"There could be additional ways to define proximity. Additionally, they should provide some exclusion options for specific policies and an ability to control the DLP engine."

"Price-wise, it is a costly product and it should be reduced."

"There is improvement in enhancing proper manageability, policies, and logs. So, log management could be improved."

"On the improvement side, when we bypass certain internet traffic types, it's currently recommended to have a one-click option, but audio and video aren't always supported. Thus, we need to bypass that kind of traffic. So, it is an area of improvement."

"The interface needs a bit of work."

Pricing and Cost Advice

"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."

"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."

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

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

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

"We are an MST and we do not pay for the solution. However, the price of the solution could be better."

"The pricing is fair."

"The product's pricing seems fair."

"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."

"Microsoft offers bundle discounts and a pay-as-you-go option."

More Microsoft Defender for Cloud Apps pricing and cost advice

"It has been relatively reasonable for what it does. Some of the additional license costs based on the advanced next-generation firewall functions are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Overall, the cost seems reasonable."

"The cost is expensive. It depends on the number of users."

"In the long run, cloud services are not inherently costly."

"My company is a Zscaler Private Access partner, so the customers pay for the license fees."

"The solution is expensive."

"The product is a bit expensive."

"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."

"The technical support is good."
