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.

Secure access has improved remote work and has reduced vulnerabilities across our workforce

Zscaler Zero Trust Exchange Platform probably needs to be more efficient because scanning takes a lot of time. Some vulnerabilities create issues, and when we wanted to identify the source of the vulnerabilities, specifically focusing on mobile ID and related areas, it was unable to provide assistance. However, according to discussions with Zscaler Zero Trust Exchange Platform, they said that by the end of mid-2026, they are exploring these features, and probably those features can be incorporated or embedded into this particular system. That is the only major negative point.In terms of responses, Zscaler Zero Trust Exchange Platform is good. In terms of controlling vulnerability, it is good. The only cons I have noticed is that it is a bit slower, and sometimes it is unable to identify the source. These are the key areas for improvement.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

"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."

"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."

"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."

"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."

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

"Our primary use case for this product is DLP,"

"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."

More iboss pros

"You can do online and offline authentication."

"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 I approve it. That part is just phenomenal."

"I appreciate the simple login feature of Cisco Duo; being able to log into your actual page and then having all your apps there is convenient."

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

"Cisco Duo has positively impacted my organization by helping to implement zero trust, ensuring that every user is protected against phishing or password theft, and reducing security incidents according to my records and reports for a year."

"Multifactor authentication and secure two-factor authentication are the most valuable features. It's been around for a while, but now it's becoming an enforced behavior as opposed to something that you used to do as optional."

"Regarding the valuable features, I would say that Duo Security is easy to use, has speed, and is dependable."

"The app has greater stability than rival solutions such as Google Authenticator, and Duo Push authentication is a valuable feature."

More Cisco Duo pros

"The VPN is great for the stability on offer and for the cloud updates and insights you can get."

"It has been helpful in maintaining our infrastructure. The granular level control it offers allows us to set application policies per application for each user."

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

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

"We don't need to connect anymore. It is automatically connected when you log on in Windows."

"The most valuable feature of Zscaler Private Access is we do not have to connect to a VPN, it is seamless. It is more convenient for us because we use one agent to cover the internet and VPN access."

"The most valuable features of Zscaler SASE include web filtering, application control, and the private access configuration."

"The most valuable features of Zscaler Private Access are reliability, scalability, and availability."

More Zscaler Zero Trust Exchange Platform pros

Cons

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

"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."

"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."

"Sometimes, obviously, there are bugs."

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

"To scale up, a new iboss Node Blade Chassis must be purchased."

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

More iboss cons

"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."

"The experience of the deployment with Cisco Duo is pretty rough."

"At the moment, I believe that more integration between Cisco Duo Identity Intelligence and the classic Cisco Duo console can be improved, since it is still a separate platform, and when I click on Identity Intelligence, I have to open a new window and log in again."

"Often, people do not receive expiration messages, and sometimes, for security reasons, accounts get disabled without notifying the end user, so they mistakenly think something has gone wrong when it really just needs to be re-enabled on the external system."

"The cost will become expensive for large user accounts."

"Scalability could be better if the price were reduced, as scaling is quite expensive."

"Cisco Duo could be improved by building the agent with the many agents we already use, such as Cisco AMP and Cisco Secure Client, which would simplify our environment by eliminating the need for a third agent for secure applications."

"I think Cisco Duo can be improved. I found the onboarding was very difficult, even for engineers who have been using similar solutions before."

More Cisco Duo cons

"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 solution needs to improve a lot of aspects."

"There could be more DLP-related features. Additionally, there needs to be flexibility for integrating ISP features."

"Users report application access or latency issues with Zscaler Private Access."

"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."

"User management can be improved."

"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."

"The pre-defined dictionaries could be improved."

Pricing and Cost Advice

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

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

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"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."

"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."

"Cisco's licensing is always a bit complicated to understand, but the price is fair. It could be more expensive than others, but the way they integrate everything, it has a fair price."

"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."

"It falls in line with everything else."

"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."

"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 haven't seen any information on the pricing in four years, so I can't comment on that."

"You pay per user when using this solution and the pricing is fair."

More Cisco Duo pricing and cost advice

"It's an affordable solution"

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

"The product has reasonable pricing."

"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."

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

"The pricing is quite high, especially when it comes to the gateway."

"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."

"As per industry leads, Zscaler CASB is an expensive solution."
