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

"Content filtering is the most useful feature of iboss."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"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."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"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."
"Our primary use case for this product is DLP,"
"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."
"It was a very easy product to install. It can be deployed very fast."
"Defender's integration with our identity solutions is critical in our current setup."
"The most effective features for data protection are data loss prevention (DLP) and data classification."
"Shadow IT discovery is the feature I like the most."
"The most valuable feature is the seamless integration across different clouds."
"It does a great job of monitoring and maintaining a security baseline. For us, that is a key element. The notifications are pretty good."
"The compliance capabilities of Microsoft Defender for Cloud Apps are quite extensive."
"If your business requirements are relatively simple, it can get the job done."
"Better logging allows us to find problems and take appropriate steps to lock them out."
"Overall, the solution does a pretty good job at web filtering."
"We don't need to connect anymore. It is automatically connected when you log on in Windows."
"With SASE, we have a single platform that covers multiple task services with which we need to control access. All the features are equally valuable."
"This secure connection allows users to connect to the Zscaler VPN and access the resources on the office network, making it a highly valuable component of our system."
"The Live Logs are a cool feature. We can directly identify issues and divert user traffic."
"As a cloud-based service, it is very easily implemented."
"The most valuable features of Zscaler Private Access are its ability to integrate with multiple IDPs and application segmentation."
"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

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Its pricing 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."
"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."
"SSL decryption: We had issues with learners using apps instead of using web browsers."
"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."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"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."
"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."
"The interface needs to be more user-friendly."
"The insights could be improved, especially in reporting. While it is possible for me to see the usage from different cloud apps, determining if critical data has been uploaded or if it is just normal transport data is difficult."
"Sometimes, we'll get false positive alarms. For example, when a SharePoint path has no file sharing, but there is an external user, it will trigger an alarm that the file has been shared with an external user... the alerting mechanism should be more precise when giving you an alert about what activity has been done with the file..."
"There are challenges with detection and there are challenges with false-positive rates."
"I would like to see them include more features in the older licenses. There are some features that are not available, such as preventing or analyzing cloud attacks."
"The areas of Microsoft Defender for Cloud Apps that need improvement are related to IAM, as they do not provide much support for local users."
"It takes some time to scan and apply the policies when there is some sensitive information. After it applies the policies, it works, but there is a delay. This is something for which we are working with Microsoft."
"Sometimes applications crash on some machines, and we’d like Zscaler to give us some information as to why that may have happened. We’d like more detailed reports."
"Users report application access or latency issues with Zscaler Private Access."
"Sometimes, support takes time since the solution has some bugs that need fixing."
"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."
"In the next release, I would like to see RE2 Regex supported."
"There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors."
"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."
"The customers would benefit from more robust documentation and conversations around configurations, as it is slightly complex."
 

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 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 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 expensive compared to one of its competitors."
"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."
"Microsoft offers bundle discounts and a pay-as-you-go option."
"Where we are right now, this is an acceptable pricing. I would like to see more transparency given to the end user. The end user given to us is via the cloud service provider. There are different programs and license models. Some include this, and some include that. It is all over the place. There can be a little more consistency or simplification in the pricing so that your parts list is not ten pages long, and you are not trying to determine, "If I have an E3, does this cover that?", or "Do I need to pay separately for the license?" Simplification would probably be better."
"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."
"The price could be better and should be reconsidered."
"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."
"I'm not totally involved in the pricing part, but I think its pricing is quite aggressive, and its price is quite similar to Netskope. Netskope has separate licensing fees or additional charges if you want to monitor certain SaaS services, whereas, with MCAS, you get 5,000 applications with their Office 365. It is all bundled, and there's no cost for using that. You only have the operational costs. In the country I am in, it is a bit difficult to get people with the required skill sets."
"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."
"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."
"My company is a Zscaler Private Access partner, so the customers pay for the license fees."
"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."
"The price is competitive."
"In the long run, cloud services are not inherently costly."
"The solution has increased prices this year."
"Zscaler CASB is an expensive solution."
"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."
