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.

Zero trust access has transformed remote connectivity and now simplifies secure app usage

Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, is very strong, though there are a few areas where improvements can be made. One challenge observed is around initial troubleshooting and visibility. While Zscaler Private Access provides logs, it can sometimes take time to pinpoint the exact cause of access issues, especially in complex environments with multiple policies and identity integration. Another area is the dependency on identity and connector health. Since Zscaler Private Access is heavily reliant on app connectors and identity providers, any issues with these components can impact user access, making proper monitoring critical. During the initial setup, policy configuration and application onboarding require careful planning, especially for larger environments with many applications. These challenges are manageable with proper design and monitoring. Overall, the platform delivers strong security and user experience. I would recommend a few improvements, especially around user interface, reporting, and troubleshooting experience. From a user interface perspective, while the platform is powerful, the policy configuration and navigation can feel complex, especially for new users. A more simplified and intuitive layout for policy mapping and application access would help reduce the learning curve. In terms of reporting, Zscaler Private Access provides logs, but having more built-in customizable dashboards and analytics would be very helpful. Better visibility into user access patterns, application performance, and real-time troubleshooting insights would improve operational efficiency. From a support and troubleshooting standpoint, it would be beneficial to have more granular centralized visibility, allowing for quick end-to-end tracing of a user request from authentication to application access without switching between multiple views. These improvements would make the platform even more efficient, especially for large-scale enterprise environments.

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."

"The security aspect of the solution, particularly the malware behind it, is excellent."

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

"From a corporate perspective, I understand that it's important to keep the company data safe."

"Content filtering is the most useful feature of iboss."

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

"This product is solid, fairly easy to use, and reliable."

"iboss is among the few products providing inline filtering where no application is needed on the device."

More iboss pros

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

"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 discovery function and the discovery catalog are really valuable, and the ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, enhances the organization by helping to manage and control cloud app usage effectively."

"We have seen a 35% to 45% cost reduction with this solution."

"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."

"The solution is helping a lot; we get very detailed reporting on security that really shows what users are doing, including what they've opened, what they're sharing, downloading, viewing, and when they are logging in."

"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."

"It gives our clients a sense of confidence that in case there are activities on some of their applications, they will get an alert and the issue will be mitigated, based on the action that has been set."

More Microsoft Defender for Cloud Apps pros

"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."

"The most valuable aspect of Zscaler Cloud DLP is its automatic DLP feature."

"Two great features that we really like on the solution are the Internet Access and Private Access."

"What I find most valuable in Zscaler Private Access is that it's a VPN, and its connectivity as a VPN is its most valuable feature."

"We don't need to connect anymore. It is automatically connected when you log on in Windows."

"The scalability is pretty good."

"The most valuable feature of Zscaler Private Access is the categorization of the dynamic URLs which keeps the customer's environment protected. The threats and the malware are correctly categorized."

"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."

Cons

"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."

"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."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

"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."

"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."

"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."

More iboss cons

"It is a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."

"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."

"Sometimes the support is actually lacking."

"They should continue integration with all other Microsoft security-related products."

"There are certain areas where the product could improve, such as some functionalities that did not work as expected."

"We are having trouble with our continuous reporting configuration and struggling with configuring the collector properly with our log parsing."

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

"It is a new thing for Microsoft, and it still has a lot of room to improve."

More Microsoft Defender for Cloud Apps cons

"The area that requires improvement is their support. The current support is lacking."

"Conflicts arise if you do not have the same management teams on the product."

"Zscaler Private Access needs to improve its collaboration with applications without compromising security."

"Price-wise, it is a costly product and it should be reduced."

"Zscaler Private Access could improve by improving external access."

"We would like to extend the SASE applications for Zscaler."

"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."

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."

"It is expensive compared to one of its competitors."

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

"We have not priced the solution recently, but they were competitive with other vendors in the past."

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

"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 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."

"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 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."

"It is a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."

"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 fair."

"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."

More Microsoft Defender for Cloud Apps pricing and cost advice

"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."

"Zscaler SASE software is quite expensive compared to other solutions"

"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."

"There is definitely an ROI."

"My company is a Zscaler Private Access partner, so the customers pay for the license fees."

"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."

"Zscaler CASB is an expensive solution."

"In the long run, cloud services are not inherently costly."
