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.

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

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

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

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

More iboss pros

"I find Fortinet FortiCASB easily customizable."

"Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps."

"Zscaler CASB's latency and architecture are excellent."

"Zscaler SASE is probably the number one cloud-based proxy security solution."

"The product’s most valuable features are data discovery, activity control, and zero trust exchange."

"The scalability by definition is kind of intrinsically built-in."

More Zscaler Zero Trust Exchange Platform pros

Cons

"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."

"Sometimes, obviously, there are bugs."

"SSL decryption: We had issues with learners using apps instead of using web browsers."

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

"File integrity monitoring would be very advantageous as an additional feature."

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

"The dashboards for local use could be better."

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

More iboss cons

"The turnaround time to deploy Fortinet FortiCASB could be improved."

"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can be better."

"Zscaler Private Access could improve by improving external access. If external parties want to access locally to my company's services, we need to onboard them into our domain, otherwise, it doesn't work. Additionally, if their company also has Zscaler Private Access, then it doesn't work. They need to log in with our domain ID, not their company ID."

"The pre-defined dictionaries could be improved."

"There is some issue while accessing the portal. It takes too long."

"Zscaler CASB breaks down at times."

"The interface needs a bit of work."

"SCMP support would be one of the biggest improvements in my opinion. More speed improvements are also required."

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

"Sometimes, support takes time since the solution has some bugs that need fixing."

More Zscaler Zero Trust Exchange Platform cons

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."

"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 expensive compared to one of its competitors."

Information not available

"The solution is expensive."

"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."

"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."
