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 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."

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

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

"Its initial setup was straightforward."

"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."

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

"It was a very easy product to install. It can be deployed very fast."

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."

More iboss pros

"Cisco Duo benefits my organization by making it easy for me to reach out to customers using Cisco Duo so they can integrate on my platform using their credentials."

"Cisco Duo is a simple and effective tool that gives detailed information about users who connect to your domain."

"It's easy to use for the security part, and it helps to improve our security posture."

"The ease of deploying Cisco Duo Security and onboarding has greatly benefited our customers."

"For one of my clients, the ROI was somewhere between 25 to 27 percent in year one."

"I rate it highly because it's something that can grow with you, whether you have very little security or a lot of security, whether it's already Cisco or not, and whether you have a mixed mess that you're trying to put into some kind of order."

"By deploying Duo, we have virtually eliminated the risk of direct deposit redirection as a result of credentials that have been compromised via phishing."

"My advice to others looking into using Cisco Duo is that it is a great product, and I recommend it for everyone, specifically for those using Cisco Secure Client."

More Cisco Duo pros

"The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting."

"The scalability is pretty good."

"Overall, Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, has been a strong and reliable solution for enabling secure access without any need for traditional VPNs."

"SASE's most valuable features are proxy and content filtering."

"The in-line DLP feature is one of the most vital features"

"The product's most valuable features are cloud-based services and secure internet access. We don't have to set up any physical appliances."

"The platform offers advanced threat protection features and embedded AI/ML capabilities, making it more proactive in blocking threats."

"The solution is cloud-based with the latest inspection engines, which I find to be amazing."

More Zscaler Zero Trust Exchange Platform pros

Cons

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

"Its pricing could be better."

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

"The reporting feature needs improvement."

"The endpoint-type solution is an area that needs some improvement."

"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."

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

More iboss cons

"I would like to see some features simplified, such as securing, configuring, and implementing Microsoft Remote Desktop."

"We had a lot of trouble configuring the password reset function, and as a result we now have a second channel that bypasses Duo to allow users to reset their password."

"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."

"Cisco Duo can be improved by exploring a way to make it a more seamless integration and by deploying an in-house server."

"We have users who move throughout the world, and their levels of connectivity change. It can be a challenge, if someone is in Bahrain, to authenticate via 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."

"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."

"For upgrades, there should be a better notification of when they're coming out. We always have a testing phase, so we need to be ahead of it. It takes us longer before we can upgrade to the newest version."

More Cisco Duo cons

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

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

"The product is not reliable."

"Zscaler Cloud DLP needs to improve its compatibility with other security tools."

"The only issue with Zscaler Cloud DLP is that it only gives you DLP protection from web traffic, which is flowing out, while a full-blown DLP solution such as Forcepoint or Symantec gives you DLP coverage for multiple channels. Zscaler Cloud DLP doesn't give you coverage for email, fax, and USB channels, and this is the only challenge or room for improvement in the solution. It's just an extension on top of what you're buying on the proxy, so it's just an added layer, and it doesn't cover DLP on a very broad level. I'm unsure if Zcaler is in the business of competing with a full-blown DLP solution, and if there's a plan to expand the features of Zscaler Cloud DLP beyond the web channel because you'll have to deploy a full-blown agent for it. I'm unsure if this is on the cards because the solution is just an added layer that you get with your proxy. I've asked the Zcaler team whether there's a plan to go full DLP in the future, but I didn't get a positive response. There isn't any feature I'd like added to Zscaler Cloud DLP currently, because anything you could think of that should be in cloud or SaaS solutions is already there, except for machine learning, as it's the only functionality that seems to be lacking in the solution. Machine learning is an additional policy available in other DLP solutions in the market, but my team didn't find it in Zscaler Cloud DLP."

"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."

"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."

"User management can be improved."

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."

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

"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."

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

"During testing we are allowed a certain number of licenses for free."

"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."

"My experience with pricing, setup costs, and licensing has been good, with no issues. I am pleased that the prices remained stable after Cisco acquired the solution."

"Its price is reasonable. It is not highly expensive."

"I haven't seen it in a while, but it's at par with everything else licensing-wise."

"The cost was reasonable. Licensing was pretty straightforward for a change."

"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."

"Duo Security's pricing is good, fair, and very comparable to today's market."

More Cisco Duo pricing and cost advice

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

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

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

"The solution has increased prices this year."

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

"It's expensive currently. But when purchasing for a large number of users, there's room to negotiate. It's really up to the procurement team."

"There is definitely an ROI."

"The cost is expensive. It depends on the number of users."
