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

"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."

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

"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."

"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."

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

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

"As I mentioned, the return on investment is significant, as it saved our office locations' bandwidth because when you are working remotely at home, your internet traffic routes directly to iboss and will not go to your office building, saving bandwidth bottlenecks and ensuring that issues with our building internet circuits will not impact your internet connectivity because you are directly going to the iboss data center."

"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."

More iboss pros

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

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

"We have seen a 35% to 45% cost reduction with this solution."

"I like the web GUI/the management interface, and I also like the security of Microsoft because, as compared to other manufacturers, it's less complex and easy to understand and work with."

"Shadow IT discovery is the feature I like the most."

"It's a full engine that you can use to discover all your assets in the cloud, whether they are on a public cloud or a private cloud."

"I would rate it a ten because I have not experienced any stability issues so far with Defender for Cloud Apps."

"There are a lot of features with benefits, including discovery, investigation, and putting controls around things. You can't say that you like the investigation part but not the discovery. Everything is correlated; that's how the tool works."

More Microsoft Defender for Cloud Apps pros

"The most valuable feature of Zscaler Private Access is the categorization of the dynamic URLs which keeps the customer's environment protected. The threats and the malware are correctly categorized."

"The in-line DLP feature is one of the most vital features"

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

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

"The most valuable features of Zscaler SASE include web filtering, application control, and the private access configuration."

"I would recommend Zscaler Cloud DLP to others because it's the best proxy product in the market at the moment."

"Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps."

"The product’s most valuable features are inbound and outbound scanning and API control."

More Zscaler Zero Trust Exchange Platform pros

Cons

"The dashboards for local use could be better."

"The reporting feature needs improvement."

"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."

"Its pricing could be better."

"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."

"The dashboards for local use could be better."

"The area I would like to see improvement in is the ability within the reporter to navigate directly to the content the user is traversing."

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

More iboss cons

"Sometimes the support is actually lacking."

"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."

"The technical support team has room for improvement."

"Sometimes the support is actually lacking."

"Since implementing this solution, we have had more support calls regarding false positives."

"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."

"Defender for Cloud apps is primarily useful for Azure apps. It has limited capabilities for applications based on other cloud platforms."

More Microsoft Defender for Cloud Apps cons

"The customers would benefit from more robust documentation and conversations around configurations, as it is slightly complex."

"Setup is a bit complex because there are many steps that need to be taken before onboarding and activating the solution."

"I can't speak to any missing features."

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

"On a scale from one to ten, I would rate Zscaler Private Access at only a three or four."

"Zscaler Private Access could improve by improving external access. If external parties want to access locally to my company's services, we need to onboard them into our domain, otherwise, it doesn't work. Additionally, if their company also has Zscaler Private Access, then it doesn't work. They need to log in with our domain ID, not their company ID."

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

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

"It is probably in line with other solutions, but I do not deal with the financial side."

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