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

"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."

"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."

"iboss is definitely very good in terms of service."

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

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."

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

"Technical support is pretty sharp and very responsive."

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

More iboss pros

"Threat detection is its key feature, and that's why we use this tool. It gives an alert if a PC is attacked or there is any kind of anomaly, such as there is a spike in sending emails or we see an unauthorized website being accessed. So, it keeps us on our toes. We get to know that there is something wrong, and we can isolate the user and find any issues with it. So, threat detection is very robust in this tool."

"It is very easy to use, which is what we look for in these types of solutions."

"The compliance capabilities of Microsoft Defender for Cloud Apps are quite extensive."

"The feature that helps us in detecting the sensitive information being shared has been very useful. In addition, the feature that allows MCAS to apply policies with SharePoint, Teams, and OneDrive is being used predominantly."

"One of the most valuable features is auditing. Some of the other protection services have issues with auditing. Microsoft Defender for Cloud has an excellent auditing technique that helps us avoid the risk of filtering or information loss. You can use different tools to guarantee these things. It allows you to conduct an in-depth exploration of applications, users, and files that are harmful or suspicious. You can also enhance your security setup by creating personalized rules or policies that help you better control traffic in the cloud."

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

"The most valuable feature of Microsoft Defender for Cloud Apps is to stop shadow IT."

"From what I've seen, it's a good product."

More Microsoft Defender for Cloud Apps pros

"We don't need to connect anymore. It is automatically connected when you log on in Windows."

"You can close your data protection gaps with Zscaler, quickly find all the classified, sensitive data across the cloud, and have protection using advanced features like Exact Data Match, document matching, and machine learning while benefiting from very good pricing, a stable solution, straightforward initial setup, and strong scalability."

"Zscaler CASB's latency and architecture are excellent."

"The most valuable features are the File Type Control and SSL bypass policies. We"

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

"It's one of the easier products on the market as far as set-ups and deployments, and even across their whole product suite, they've made it pretty simple."

"The platform offers advanced threat protection features and embedded AI/ML capabilities, making it more proactive in blocking threats."

"It has been helpful in maintaining our infrastructure. The granular level control it offers allows us to set application policies per application for each user."

Cons

"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

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

"Sometimes, obviously, there are bugs."

"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."

"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."

"Its pricing could be better."

"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."

More iboss cons

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

"Generally, the pricing can always be improved along with the management system."

"This service would be better if it had a separate license, only for this service, that could be used to track usage."

"We would like to get more information from the endpoint. I don't get enough detailed information right now on why something failed. There is not enough visibility."

"We sometimes get errors when we create policies, which is somewhat annoying because some policies stop working due to misconfigurations. We find this challenging because it limits our options for troubleshooting an issue."

"Licensing cost is a significant concern. With Defender Plan 1, Microsoft Defender for Cloud Apps comes with a pay-per-use model."

"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 would like to get more information from the endpoint. I don't get enough detailed information right now on why something failed."

More Microsoft Defender for Cloud Apps cons

"There is some issue while accessing the portal. It takes too long."

"Zscaler Cloud DLP needs to improve its compatibility with other security tools."

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

"The solution needs to improve a lot of aspects."

"User management can be improved."

"Occasionally, issues arise in the LogStack by a third party, particularly for government websites accessed by numerous users."

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

"It has massive room for improvement. The Zscaler product itself is okay, but it doesn't give enough granularity for us as an organization to stipulate rules or processes, especially for data-driven services. For instance, we can stick on SSL inspection, but it's just a click box. It doesn't allow us to go any further into the detail of the SSL inspection. We also can't pull it out without having an additional logging server. It just doesn't give us enough granularity. They should give us more control over the interfaces because it is all backend. They weren't very open to discussing their backend architecture with us in terms of their own data centers. They can maybe a little bit more open about what components are there and how the backend infrastructure works alongside Zscaler. Its licensing can be better. Some of the additional licensing costs are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Their support should also be improved. I initially had a consultant from Zscaler for its deployment, but the support that I had throughout the deployment of the project wasn't the best."

Pricing and Cost Advice

"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."

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

"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."

"This product is not expensive."

"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."

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

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

"The pricing is fair."

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

"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."

More Microsoft Defender for Cloud Apps pricing and cost advice

"In terms of market positioning, I would describe Zscaler Private Access as offering optimal pricing. Based on our experience, Cato Networks tends to be slightly more expensive."

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

"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."

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

"The pricing is quite high, especially when it comes to the gateway."

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

"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."
