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

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"Its initial setup was straightforward."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"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."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"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 solution has massively improved our security posture, giving us full visibility into what our staff does online."
"It's simple. It's reliable. I haven't had any issues with it."
"Duo is a very consistent product and flexible in how it can be deployed and has good support."
"The technical support is of a very high level, and if you have a problem they will be able to support you, logging in remotely as an engineer to give assistance, and with the upgraded license the support is even better and they will do everything for you if you have a problem, so the support is extremely good."
"Cisco Duo benefits the company by increasing the security footprint, and it is easy to manage users, disable users, or bypass if needed in case of an emergency."
"The solution is easy to use."
"Cisco Duo has strengthened the ability to defend against both phishing and identity-based attacks."
"Cisco Duo is quick to deploy and easy to start."
"It is very easy for users to enroll, and there are a lot of insights that we get from using the app on devices that people use to authenticate."
"Two great features that we really like on the solution are the Internet Access and Private Access."
"I like its ease of use. It has a single pane of glass for the ZIA and ZPA pieces. It is very manageable. It is also very easy to deploy for secure access, and it gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway."
"The most valuable aspect of Zscaler Cloud DLP is its automatic DLP feature."
"It's one of the easier products on the market as far as set-ups and deployments, and even across their whole product suite, they've made it pretty simple."
"The user interface of Zscaler Private Access is excellent. With proper knowledge and expertise, one can efficiently handle intricate enterprise environments without feeling overwhelmed. This leads to exceptional productivity for managed service providers. The user experience is remarkably streamlined, enabling the management of even the most complex enterprise setups without any excessive complications."
"I would recommend Zscaler Cloud DLP to others because it's the best proxy product in the market at the moment."
"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."
"I like the web filtering capabilities."
 

Cons

"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."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"File integrity monitoring would be very advantageous as an additional feature."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"I am currently doing a PoC of the zero trust aspect of it. Compared to other similar solutions, it is hard to get around each feature. It takes a while to get used to it."
"Compared to other vendors, Cisco Duo is on the pricey end."
"Cisco Duo can be improved by exploring a way to make it a more seamless integration and by deploying an in-house server."
"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."
"One downside of Cisco Duo is the expense, as there are clients that can afford only the basic package, which does not include Geo-fencing, leaving them unable to pay for the more expensive level, which I do not feel justifies the double price of that upper tier version."
"They can make authentication easier. It should be done in a shorter time. Sometimes, it can take a bit more time to get the answer on your phone. You have to wait a bit longer to get the SMS code and other things. There can be some internet or connection issues. They should make it faster because sometimes, it's urgent, and you need to access something as soon as possible."
"When you come to the push in Duo Security, there are some integrations where you have to use the code instead of the push functionality."
"To improve Cisco Duo, the biggest consideration is the licensing standpoint; the most common issue I've found is customers not setting up the Active Directory sync properly, leading to inflated licensing usage when they try to delete inactive users that are still being charged."
"I think that the dashboard needs to be improved."
"The solution's granularity should be improved because it has limited granular options to control, visible, allow, block, delay, and receive."
"The interface needs a bit of work."
"Those folks will likely have some issues."
"We would like to extend the SASE applications for Zscaler."
"The menu for the ZIA portal could be organized a little bit differently. The most-used modules should be at the top of the menus, not somewhere near the bottom, some of them are not organized well in my opinion."
"Sometimes, support takes time since the solution has some bugs that need fixing."
"The pricing for Private Access seems to be on the expensive side, and I believe they should consider making it more competitive with other solutions."
"The area that requires improvement is their support. The current support is lacking."
 

Pricing and Cost Advice

"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."
"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."
"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."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"Its price is reasonable. It is not highly expensive."
"Our licensing fee is currently on an annual basis."
"The licensing is very good because it does not cost a lot of money. It's affordable for all-sized customers, including enterprises. There is an additional cost for premium support."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"During testing we are allowed a certain number of licenses for free."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"I only need the solution for IT staff, which makes it relatively cheap. If I deployed it for the whole company, it would be costly, so it depends on the number of users. Duo Security is affordable compared to other products in the segment."
"It is an auto-renewal subscription service."
"Zscaler Private Access is extremely expensive."
"It's an affordable solution"
"The pricing is quite high, especially when it comes to the gateway."
"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."
"Zscaler CASB is an expensive solution."
"My company is a Zscaler Private Access partner, so the customers pay for the license fees."
"In the long run, cloud services are not inherently costly."
