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 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."
"Technical support is pretty sharp and very responsive."
"Our primary use case for this product is DLP,"
"It was a very easy product to install. It can be deployed very fast."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"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."
"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."
"All features of the solution are effective, particularly those involved in identifying vulnerabilities and updates."
"We get fewer threats to remediate due to the two-factor authentication, which does not allow as many threats through."
"Duo offers dual-factor authentication for our logins; I put in my credentials and hit go, then I get an alert on my Apple Watch and approve it, and that part is just phenomenal."
"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."
"Cisco Duo is a simple and effective tool that gives detailed information about users who connect to your domain."
"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 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."
"By deploying Duo, we have virtually eliminated the risk of direct deposit redirection as a result of credentials that have been compromised via phishing."
"Two great features that we really like on the solution are the Internet Access and Private Access."
"Has a good zero trust feature."
"It is straightforward to set up."
"Before Zscaler, we used to use a lot of other products, however, when we were introduced to Zscaler we became confident it could meet the use cases."
"The platform offers advanced threat protection features and embedded AI/ML capabilities, making it more proactive in blocking threats."
"The most valuable features are the File Type Control and SSL bypass policies. We"
"The scalability of the solution is great."
"Overall, the solution does a pretty good job at web filtering."
 

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."
"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."
"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"SSL decryption: We had issues with learners using apps instead of using web browsers."
"Its pricing could be better."
"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"I have not seen ROI with Cisco Duo; probably the opposite, because it impedes productivity time to be able to get into the system. You have to authenticate and do your regular login and your Active Directory logins."
"I would like to see some features simplified, such as securing, configuring, and implementing Microsoft Remote Desktop. Other than that, the solution was rock solid throughout my time administering it."
"One area that might be improved is that setting up SMS texting is not as easy as using the app, even though it does support it."
"Regarding the pricing, setup costs, and licensing, I find that for some companies using Azure, they question why they should switch when they already have Microsoft Authenticator, which can make it commercially challenging when explaining why they need to transition to Cisco Duo."
"We have had instances where Duo Security stops working on a user's device, which we have fixed by uninstalling and then reinstalling it."
"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."
"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."
"The price of Cisco Duo could be better."
"What could be improved in Zscaler Private Access is its notification. For example, if there's a speed issue, there should be a pop-up that alerts the user about it. If there is a network quality issue, for example, it isn't good enough to connect to, or the network quality is bad, there should be a notification from the solution. Zscaler Private Access also needs improvement in terms of its interface and security."
"There is improvement in enhancing proper manageability, policies, and logs. So, log management could be improved."
"It needs to offer SSO, single sign-on, and items of that nature."
"The area that requires improvement is their support. The current support is lacking."
"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."
"It has a limitation, if you are creating a rule or something for a web application or something, you could only add five users, not more than that. Five or four users are only included in a rule. If you want to create a rule for more than five or four users, you have to go through other methods, not particularly with the application. Working within the application with this method would be quite easy as compared to listing a URL or a normal IP address."
"The scalability is a weak point right now. Its scaling capabilities are lacking, and we'd like to see that improve in the future."
"The interface needs a bit of work."
 

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."
"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"My experience with the pricing, setup cost, and licensing of Cisco Duo has been great. We've been there for 10 years. While we haven't gone through the setup part for a while, licensing is straightforward and convenient for higher education because student populations are included. So, we don't have to pay extra for it. We just pay for our knowledge workers, which has been great, and the cost is reasonable."
"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."
"Its price is reasonable. It is not highly expensive."
"Duo Security is free."
"The pricing was a lot more than what we were paying for our previous solution."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."
"As per industry leads, Zscaler CASB is an expensive solution."
"It is an auto-renewal subscription service."
"The cost is expensive. It depends on the number of users."
"It's an affordable solution"
"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."
"In the long run, cloud services are not inherently costly."
"In terms of market positioning, I would describe Zscaler Private Access as offering optimal pricing. Based on our experience, Cato Networks tends to be slightly more expensive."
