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.

Supports seamless authentication for users across multiple organizations and personal portals
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.

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 definitely very good in terms of service."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"Its initial setup was straightforward."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"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."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Once you break that curve, it gives end users a sense of security where they know that if they're trying to sign on to Office 365 or some other application, they need to authenticate with Duo to make sure that they have the multi-factor authentication."
"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."
"Multifactor authentication is the most valuable feature."
"Compared to Cisco, the general support I experience is fantastic; I have no complaints about it."
"Cisco Secure solutions are great for detecting and remediating threats across our infrastructure from end to end. The integration of Talos in SecureX is great. Everything is clear in one dashboard. You have a dashboard there, your dashboard, and now you can have one look in your dashboard and see everything. It's on one pane of glass."
"The ease of deploying Cisco Duo Security and onboarding has greatly benefited our customers."
"What I most appreciate about Cisco Duo is the ease of use."
"Cisco Duo seems very scalable; in my experience, I started with a small-medium business, and in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well."
"The VPN is great for the stability on offer and for the cloud updates and insights you can get."
"I like the web filtering capabilities."
"You can close your data protection gaps with Zscaler. You can quickly find all the classified, sensitive data across the cloud."
"The most valuable features of Zscaler Private Access are reliability, scalability, and availability."
"Zscaler Cloud DLP provides you with basic DLP features that you get out of the box such as keywords, regular expressions, and data identifiers, for example, your social security numbers, and credit card numbers, with everything built into the product, so you can directly use those features within the policies. You don't need to create it from scratch, and to me, this is the biggest benefit of Zscaler Cloud DLP. You have a lot of templates to choose from in the solution, rather than having to create templates from scratch or reinvent templates."
"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."
"SASE's most valuable features are proxy and content filtering."
"Zscaler Private Access is a platform that eliminates the complexity of VPN configuration."
 

Cons

"Its pricing could be better."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"The dashboards for local use could be better."
"The dashboards for local use could be better."
"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"I wouldn't mind seeing some options for remembering a device for a short period of time or a specific login, particularly for administrative engineering staff, as we may be logging in to four or five different services."
"With Cisco Duo, you have to do that, and customers complain about that process. At some point, you need to be technically savvy to understand how to use Cisco Duo."
"We already have Active Directory enabled in our routers and switches. However, if we could do two-factor authentication, then it could go a long way since no one's getting into them unless you want them to."
"Cisco Duo is definitely not doing things that others are not doing, so there is no unique selling proposition."
"The deployment experience was more difficult than we expected because we had some problems with the version of the OS that we have in our servers."
"Cisco Duo could be improved, possibly by adding features for the healthcare space. If you're selling something to a healthcare provider, there needs to be consideration for how to launch Cisco Duo with a handheld device that is not native, where you can install the application."
"Cisco Duo has not helped my company reduce its overall authentication-related costs, as it is a cost above what we already have."
"There might be a little slowness, but that could be my connection."
"Price-wise, it is a costly product and it should be reduced."
"Having a Zscaler-specific device could streamline this process and provide a more consistent user experience across diverse branches."
"We'd like to have two-factor authentication that is quite simple."
"Occasionally, there are certain delays in report generation."
"Zscaler CASB breaks down at times."
"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."
"We would like to extend the SASE applications for Zscaler."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"The overall pricing for iboss is very competitive and transparent."
"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 was reasonable. Licensing was pretty straightforward for a change."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"Cisco has the most expensive products because market leaders tend to charge a lot."
"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."
"Duo Security is free."
"The product’s pricing is reasonable."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"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 technical support is good."
"The pricing is quite high, especially when it comes to the gateway."
"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 solution is expensive."
"The product is a little more expensive than other tools."
"Zscaler Private Access is extremely expensive."
"In the long run, cloud services are not inherently costly."
