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.

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 has significantly lowered the number of security incidents. It is crazy how much it blocks and how much it is aware of the outside danger."
"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."
"Our primary use case for this product is DLP,"
"Its initial setup was straightforward."
"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. 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 chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"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."
"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 single pane of glass management works very well. That feature is very important because we have a lot of admins who have to manage Duo, and it's much easier when it's a single pane of glass. That single pane is also great because it's easy to enroll new devices."
"Duo is a cloud-based product and it is a good product to maintain the security for the VPN."
"The anti-phishing feature is the most valuable."
"The winning point for Cisco Duo over others is its simplicity; it is just a security solution in a box, and it integrates very easily."
"Duo is a very consistent product and flexible in how it can be deployed and has good support."
"The two-factor login is great. I receive a message and just have to press okay."
"Duo has allowed us to add an additional layer of security to our organization and to establish trust for every access request and secures our environment."
"The platform offers advanced threat protection features and embedded AI/ML capabilities, making it more proactive in blocking threats."
"On DLP terms, Zscaler Cloud DLP ensures that data doesn't go outside of the organization. So on the network level, Zscaler does a pretty good job."
"Zscaler CASB's latency and architecture are excellent."
"It does the job. What it is needed for. I can use it for VPN, I can use it for secure connections, I can use it as a firewall. So the solution does the job."
"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."
"Has a good zero trust feature."
"I like its ease of use; it has a single pane of glass for the ZIA and ZPA pieces, is very manageable, is very easy to deploy for secure access, and gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway."
"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."
 

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."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"The dashboards for local use could be better."
"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."
"File integrity monitoring would be very advantageous as an additional feature."
"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."
"It took me a while to figure it out. I went to every user and forced them to set it up. I might have done it the long way."
"Regarding the Premier licensing, it is a little bit pricey, but it is in the market range with the competitors."
"Cisco Duo is stable, but occasionally there are emails about incidents that affect some services temporarily."
"There could be improvements made to the dashboards and more integration with the rest of the Cisco ecosystem."
"It is good on the functionality side, but their pricing model is a little bit weird."
"An improvement for Cisco Duo would be a simplification of the licensing model since it's quite complicated to know what's included or not, especially now as it's part of Cisco Secure User Suite, and there are many modifications happening regarding the licensing."
"There is a little bit of apprehension for some users thinking, well, "How do I know this app is not collecting personal information from my personal device?""
"I think the prices of Cisco Duo are quite fair, but the main problem is that Microsoft Authenticator is built-in with Microsoft 365, so everyone is switching to that and not using Cisco Duo because it is a standalone product that costs extra, despite the price being fair."
"This is a great solution, I'm just searching for an alternative because the costing or the commercials for this type of solution tends to be a little high, although we have been using it for a year already."
"Zscaler CASB should include integrations with other SaaS applications."
"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."
"Sometimes, support takes time since the solution has some bugs that need fixing."
"The connectivity monitoring part should be included in the core license without any extra charges."
"Price-wise, it is a costly product and it should be reduced."
"Zscaler Private Access's reporting is poor. We should have more insight into the reports regarding what is blocked and allowed."
"While Zscaler supports client-initiated connections, it does not support server-initiated connections. This is a feature that Zscaler may consider adding in the future."
 

Pricing and Cost Advice

"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."
"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."
"It is probably in line with other solutions, but I do not deal with the financial side."
"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 overall pricing for iboss is very competitive and transparent."
"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"With regard to pricing, for a small business buying a one off, it's pretty expensive. If it's an enterprise that has thousands of employees, however, it's really nothing to protect your data because if your network goes down or it's breached, you're losing millions of dollars every minute. When it comes to a large enterprise, it's priced where it should be because you're talking business to business. You're not talking business to consumer."
"The pricing was a lot more than what we were paying for our previous solution."
"Their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. There are no additional costs to the standard licensing costs."
"Its price is reasonable. It is not highly expensive."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"The product has reasonable pricing."
"Zscaler Private Access is extremely expensive."
"The solution is expensive."
"There is definitely an ROI."
"As per industry leads, Zscaler CASB is an expensive solution."
"Zscaler CASB is an expensive solution."
"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."
"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."
