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.

Secure access has improved remote work and has reduced vulnerabilities across our workforce
Zscaler Zero Trust Exchange Platform probably needs to be more efficient because scanning takes a lot of time. Some vulnerabilities create issues, and when we wanted to identify the source of the vulnerabilities, specifically focusing on mobile ID and related areas, it was unable to provide assistance. However, according to discussions with Zscaler Zero Trust Exchange Platform, they said that by the end of mid-2026, they are exploring these features, and probably those features can be incorporated or embedded into this particular system. That is the only major negative point.In terms of responses, Zscaler Zero Trust Exchange Platform is good. In terms of controlling vulnerability, it is good. The only cons I have noticed is that it is a bit slower, and sometimes it is unable to identify the source. These are the key areas for improvement.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"Our primary use case for this product is DLP,"
"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."
"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"The console is cloud-based, which is something I really appreciate."
"Content filtering is the most useful feature of iboss."
"The compliance capabilities of Microsoft Defender for Cloud Apps are quite extensive."
"The most valuable feature of Microsoft Defender for Cloud Apps is to stop shadow IT."
"Shadow IT discovery is the feature I like the most."
"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."
"I like the alert policies because they are quite robust. It has some built-in templates that we can easily pick up. One of them is the alert for mass downloads, when a particular user is running a massive download on your SharePoint site."
"Everything from Microsoft is integrated. You receive regular reports on them all. You can push your reports, logs, and security alerts, which are all integrated. It is crucial that these solutions work natively together to deliver coordinated detection and response across our environment."
"If your business requirements are relatively simple, it can get the job done."
"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."
"On DLP terms, Zscaler Cloud DLP ensures that data doesn't go outside of the organization. So on the network level, Zscaler does a pretty good job."
"The product's most valuable features are cloud-based services and secure internet access. We don't have to set up any physical appliances."
"The most valuable features are the File Type Control and SSL bypass policies. We"
"The most valuable features of this solution are the CASB solutions, which is protecting their Office 365."
"The VPN is great for the stability on offer and for the cloud updates and insights you can get."
"I find all Zscaler Private Access features valuable because each replaces flawed technologies, such as EPAs being replacements for VPN and PR as a replacement for PAM, so I can't mention only one valuable feature. Overall, Zscaler Private Access is a good solution."
"The most valuable features of Zscaler SASE include web filtering, application control, and the private access configuration."
"The customer service and support are very good."
 

Cons

"The dashboards for local use could be better."
"File integrity monitoring would be very advantageous as an additional feature."
"The reporting feature needs improvement."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"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."
"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."
"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."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"Defender for Cloud apps is primarily useful for Azure apps. It has limited capabilities for applications based on other cloud platforms."
"There are certain areas where the product could improve, such as some functionalities that did not work as expected."
"There could be more granular roles that are out of the box included in the product."
"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."
"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."
"Generally, the pricing can always be improved along with the management system."
"Defender could integrate better with multi-cloud and hybrid environments. It requires some additional configuration to ingest data from non-Azure environments and integrate it with Sentinel."
"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."
"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."
"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."
"Zscaler CASB should include integrations with other SaaS applications."
"I rate it a seven because I am still working through some kinks from a performance and a support perspective."
"To enhance their offering, it is advisable for them to focus on strengthening the foundation of their architecture. Additionally, they should consider integrating a broader range of services that go beyond what managed service providers typically offer independently."
"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."
"There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors."
"More on-prem infrastructure is required when Zscaler Private Access is to be implemented as a single point of entry."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"The overall pricing for iboss is very competitive and transparent."
"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 have not priced the solution recently, but they were competitive with other vendors in the past."
"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."
"The pricing is a little bit high but right now, we are okay with it because of the compatibility with Office 365, Teams, and Azure AD."
"Microsoft offers bundle discounts and a pay-as-you-go option."
"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."
"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 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 E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."
"This product is not expensive."
"The price is competitive."
"In the long run, cloud services are not inherently costly."
"The technical support is good."
"The product is a little more expensive than other tools."
"The licensing model for Zscaler Cloud DLP allows you to only buy what you need. You don't need to buy it as a whole, so it's good."
"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."
"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."
"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."
