Cloud gateway has strengthened remote web security and now needs better Mac and ISP support

The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Layered security has protected our cloud AI apps and significantly reduced attack incidents

The best features Proofpoint Cloud App Security Broker offers are multilayer protection against security attacks and escalation. The escalation feature in Proofpoint Cloud App Security Broker is valuable because we are using more and more users, and it is very scalable in relation to the number of users using the same app on the cloud. The performance of Proofpoint Cloud App Security Broker stands out as the number of attacks blocked is more than 90%. Proofpoint Cloud App Security Broker has positively impacted my organization by resolving all of the security issues related to app security. I can share specific outcomes, such as a reduction in the number of incidents, which is more than 90% related to the past.

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

"iboss is easy to use despite its complexity. Multiple engineers manage it, but it's significantly more straightforward to administer than traditional VPNs and web proxies."

"As I mentioned, the return on investment is significant, as it saved our office locations' bandwidth because when you are working remotely at home, your internet traffic routes directly to iboss and will not go to your office building, saving bandwidth bottlenecks and ensuring that issues with our building internet circuits will not impact your internet connectivity because you are directly going to the iboss data center."

"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 console is cloud-based, which is something I really appreciate."

"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. 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."

"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."

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

More iboss pros

"The quarantine feature is the solution's most valuable aspect."

"The product is stable."

"Proofpoint Cloud App Security Broker has positively impacted my organization by resolving all of the security issues related to app security."

"From stability and availability standpoints, it is pretty good."

"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."

"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."

"The VPN is great for the stability on offer and for the cloud updates and insights you can get."

"The solution offers a simplified network infrastructure and security functions and it enables secure remote access for the users"

"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."

"This is a product that I recommend for anybody who wants a scalable, cloud-based solution."

"The product’s most valuable features are inbound and outbound scanning and API control."

"It is a stable solution."

"Has a good zero trust feature."

Cons

"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."

"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."

"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."

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

"The reporting feature needs improvement."

"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."

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

More iboss cons

"The TLS encryption needs to be improved. It's not state of the art."

"They are priced significantly higher and less cost-effective than alternative options."

"I think some of the hiccups that we had were with the number of domains that we had and how that had to be implemented in Proofpoint."

"Proofpoint Cloud App Security Broker should be cheaper."

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

"It needs to offer SSO, single sign-on, and items of that nature."

"The granularity in blocking is not sufficient, as new domains are automatically blocked for 30 days without further information."

"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."

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

"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."

"We have issues with the tool's maintenance and networking. It should be able to work in offline mode as well."

"There aren't really any missing features that I have witnessed."

Pricing and Cost Advice

"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."

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

"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."

"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 tool's most valuable feature is reporting. It helps us understand what's going on in our environment."

"We had an enterprise contract with them for about 32,000 users at that point, which has now grown."

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

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

"There is definitely an ROI."

"Zscaler Private Access is extremely expensive."

"The product has reasonable pricing."

"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."

"The pricing is quite high, especially when it comes to the gateway."

"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."
