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

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"The security aspect of the solution, particularly the malware behind it, is excellent."
"From a corporate perspective, I understand that it's important to keep the company data safe."
"The console is cloud-based, which is something I really appreciate."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"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."
"The security aspect of the solution, particularly the malware behind it, is excellent. That's something that really helped us out. It's not just a simple proxy that just blocks the insights of potential threats that come on behind it. They do malware detection and that helps us a lot."
"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."
"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."
"We have become more aware of what services our users are using, how often they are using them, and what data is being sent out of the organization and to which services. So, it is really a lot about visibility and helping us make decisions based on that. It drives some of our policy decisions for adding extra security controls."
"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."
"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."
"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."
"The benefit you get is that you are able to monitor all your applications and control the data that goes out of those applications."
"Defender helps us control which applications are being used and gain more security insight into remote and hybrid users based on user identity and log in location. You can also integrate Defender for Cloud Apps with Defender for Endpoint to extend its capabilities."
"The most valuable feature is the seamless integration across different clouds."
"The VPN is great for the stability on offer and for the cloud updates and insights you can get."
"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."
"The only advantage I see is no more connection is required by the users."
"The product provides a seamless user experience."
"The product’s most valuable features are data discovery, activity control, and zero trust exchange."
"The most valuable feature is its ability to establish connectivity for remote users and remote endpoints. It offers a high level of granularity compared to typical VPNs, which also encapsulate a lot of I/O."
"Has a good zero trust feature."
"From a cost perspective, I would say fair market value, and then from an efficiency perspective, I notice a very good user experience, which is easy to use with Zscaler Zero Trust Exchange Platform."
 

Cons

"The endpoint-type solution is an area that needs some improvement."
"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."
"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."
"SSL decryption: We had issues with learners using apps instead of using web browsers."
"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 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."
"Its pricing could be better."
"The dashboards for local use 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."
"MCAS doesn't have many reporting capabilities, and it's really an operational nightmare to get all these things done at this point in time by using MCAS."
"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."
"The product is very good so far, however, it would be better if it could include more up-to-date threat protection."
"There are certain areas where the product could improve, such as some functionalities that did not work as expected."
"Defender for Cloud Apps could come with more configured policies out of the box. Also, integration could be easier. Integration is moderately difficult because Microsoft hasn't developed a solution that unifies device onboarding and management. You have to use Intune to manage devices and Defender for Endpoint to enforce policies. They need to fix their integration, but I believe they will straighten it out by the end of the year."
"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. I would love to have reports with more fine-tuning or granularity, and more predefined reports."
"Generally, the pricing can always be improved along with the management system."
"Price-wise, it is a costly product and it should be reduced."
"The menu for the ZIA portal could be organized a little bit differently. The most-used modules should be at the top of the menus, not somewhere near the bottom, some of them are not organized well in my opinion."
"Zscaler Cloud DLP needs to improve its compatibility with other security tools."
"Occasionally, issues arise in the LogStack by a third party, particularly for government websites accessed by numerous users."
"The area that requires improvement is their support. The current support is lacking."
"Zscaler Private Access could improve by improving external access."
"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."
"I rate it a seven because I am still working through some kinks from a performance and a support perspective."
 

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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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."
"It is expensive compared to one of its competitors."
"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."
"The price could be better and should be reconsidered."
"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."
"We have an educational licensing agreement. It's a customer agreement for multiple years."
"Microsoft offers bundle discounts and a pay-as-you-go option."
"This product is not 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."
"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."
"It is a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."
"Zscaler CASB is an expensive solution."
"Zscaler SASE software is quite expensive compared to other solutions"
"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 DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."
"The product is a bit expensive."
"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."
"As per industry leads, Zscaler CASB is an expensive solution."
