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

"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."
"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."
"Content filtering is the most useful feature of iboss."
"It was a very easy product to install. It can be deployed very fast."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"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."
"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."
"The integration within the entire Defender suite is highly valuable because it allows for communication between different components and offers pretty decent correlations."
"The general usability of the solution is very straightforward."
"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."
"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."
"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."
"The solution is cloud-based with the latest inspection engines, which I find to be amazing."
"Has a good zero trust feature."
"Subsequently, after this, there is a huge reduction, as the vulnerabilities, especially the security bugs that were coming prior to Zscaler Zero Trust Exchange Platform, were about 20,000 to 22,000 and have come down more than 40 percent, which is definitely an advantage over the previous product."
"The most valuable feature of Zscaler Private Access is we do not have to connect to a VPN, it is seamless. It is more convenient for us because we use one agent to cover the internet and VPN access."
"The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting."
"The most valuable features of Zscaler SASE include web filtering, application control, and the private access configuration."
"Overall, the solution does a pretty good job at web filtering."
"The most valuable features are the File Type Control and SSL bypass policies. We"
 

Cons

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."
"Its pricing could be better."
"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."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"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."
"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."
"In the future, I would like to see more plug-and-play capabilities that use AI to tell you what needs to be done. It would be helpful if it scanned our devices and made security suggestions, on a configuration basis."
"I want them to enhance in-session policy."
"We would like to get more information from the endpoint. I don't get enough detailed information right now on why something failed. There is not enough visibility."
"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."
"The integration with macOS operating systems needs to be better."
"We are having trouble with our continuous reporting configuration and struggling with configuring the collector properly with our log parsing."
"The documentation could be improved as it is not updated immediately when Microsoft makes changes. Users must wait a few weeks for the changes to be reflected in the documentation."
"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."
"User management can be improved."
"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."
"More on-prem infrastructure is required when Zscaler Private Access is to be implemented as a single point of entry."
"There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors."
"It needs to offer SSO, single sign-on, and items of that nature."
"There aren't really any missing features that I have witnessed."
"Price-wise, it is a costly product and it should be reduced."
 

Pricing and Cost Advice

"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."
"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."
"The cost could be improved when you need to pay for anything. For example, refreshing files takes time to load, though it may be my Internet. To improve the refresh time, Microsoft says that we need to pay for a Premium license, and I don't like paying for things that help make a solution better."
"The price could be better and should be reconsidered."
"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."
"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."
"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 E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."
"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."
"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."
"As per industry leads, Zscaler CASB is an expensive solution."
"In the long run, cloud services are not inherently costly."
"The product is a bit expensive."
"There is definitely an ROI."
"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."
"The pricing is quite high, especially when it comes to the gateway."
