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

"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."

"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."

"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."

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

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

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

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

More iboss pros

"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."

"The product’s most valuable feature is SQL database."

"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."

"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."

"I like the web GUI/the management interface. I also like the security of Microsoft. 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."

"On-demand scanning is the most valuable feature. In addition, it's a fairly fluid product. It syncs back to the cloud and provides metrics. It's pretty intelligent."

"The most valuable feature of Microsoft Defender for Cloud Apps is that we are primarily using only the Defender for Cloud on the Azure Cloud."

More Microsoft Defender for Cloud Apps pros

"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."

"The solution is cloud-based with the latest inspection engines, which I find to be amazing."

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

"I like the web filtering capabilities."

"It does the job. What it is needed for. I can use it for VPN, I can use it for secure connections, I can use it as a firewall. So the solution does the job."

"The initial setup is easy."

"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."

"You can close your data protection gaps with Zscaler. You can quickly find all the classified, sensitive data across the cloud."

More Zscaler Zero Trust Exchange Platform pros

Cons

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

"To scale up, a new iboss Node Blade Chassis must be purchased."

"Sometimes, obviously, there are bugs."

"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."

"Its pricing could be better."

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

More iboss cons

"The technical support team has room for improvement."

"I would prefer to have filtering options incorporated within the policies, enabling the solution to perform tasks beyond mere blocking or allowing."

"I would like for it to be available on Mac and for it to support all of the features of Microsoft financing products. It is really for Windows."

"An area of Microsoft Defender for Cloud Apps that needs to be improved or enhanced is the reporting function. In the beginning, there was a good reporting function which gave us a sort of monthly overview report. But that has gone away."

"Microsoft Defender for Cloud Apps’s technical support services needs improvement."

"The interface needs to be more user-friendly."

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

"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."

More Microsoft Defender for Cloud Apps cons

"We faced certain migration and implementation challenges in executing the tasks, so I would suggest improvement related to the stability of the solution."

"We'd like to have two-factor authentication that is quite simple."

"The connectivity monitoring part should be included in the core license without any extra charges."

"The interface needs a bit of work."

"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."

"It's an expensive solution."

"The DX layer could be better if it had improved visibility."

"It would be better if the Zscaler Private Access team made it easier for people to find subscriptions on the portal, mainly information on what my customers subscribed to or the type of licenses purchased."

Pricing and Cost Advice

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

"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."

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

"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."

"We have an educational licensing agreement. It's a customer agreement for multiple years."

"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."

"The pricing is fair."

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

"This product is not expensive."

"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."

"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."

More Microsoft Defender for Cloud Apps pricing and cost advice

"The product has reasonable pricing."

"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."

"The product is a little more expensive than other tools."

"The solution is expensive."

"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."

"The technical support is good."

"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."

"As per industry leads, Zscaler CASB is an expensive solution."
