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.

Ensures comprehensive protection with seamless threat logging and efficient policy management

My favorite feature of Cisco Umbrella is probably just the DNS and the fact that when a security threat happens, all of that gets logged in their Umbrella portal, and it's very easy to find who's been accessing the site and how many people have accessed it, so that we can go to them and make sure they're not compromised. The features of Cisco Umbrella benefit my company by providing less time to search for things through logs, to look for what we need. It's just one place to go, and we just search for it, and we find it really fast. The fact that there's a virtual database that has all that information is great on our portal.

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

"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."

"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."

"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."

"The console is cloud-based, which is something I really appreciate."

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

"Its initial setup was straightforward."

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

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

More iboss pros

"We are very new users of the solution and are still in the exploration stages, but we are happy with the product thus far."

"Some clients only want DNS security, while others want more of the advanced features that it has available."

"The most valuable features are the dashboard, visibility, and reporting capabilities. Our customers can see how much Umbrella is protecting their organization. If you don't know what you've got, you can't protect it. With Umbrella, you get the visibility and see the protection that it's providing. We can get PDF reports on a weekly basis of any malware activities and any denial of service or command-and-control-type activities."

"We can have a full overview and a quick overview of all the DNS requests. For us, it's quite important."

"Cisco Umbrella is a totally different solution. They are the first to come up with this idea of security. It's a totally new concept of security for everybody, for every time, real time, perfectionism."

"It is user-friendly. It is easy to manage the solution."

"I was able to implement it myself. It was really easy to install. You could install it on a server locally if you want to. If you have the biggest site, you would do that, but for my site, it was just directing all the traffic out through the Cisco Umbrella DNS. It was really handy. When the owners of the company went overseas, I knew that they would be secure because even if they were not on the company network, they would still go through the Cisco Umbrella servers. It was a complete solution for protecting the company with outgoing data."

"It has helped reduce my unit's security events."

More Cisco Umbrella pros

"The best feature is the ability to establish the connection between your public network and automatically connect to the intranet connection."

"The ZPA is a unique feature which offers VPN along with all the additional security needed."

"It has some good data security and WIP features, providing secure Internet access."

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

"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."

"The initial setup is easy."

"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."

"Overall, the solution does a pretty good job at web filtering."

More Zscaler Zero Trust Exchange Platform pros

Cons

"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."

"Our iboss subscription access should be more secure with an OTP or VPN etc. It is easy to gain access if, for example, hackers obtain my username and password."

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

"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. This type of encryption is tough for any appliance in a BYOD environment."

"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."

More iboss cons

"In the next release, I would like to see the integration of VDI NSX with Cisco Umbrella."

"Cisco Umbrella could be improved by making the policies more granular, as in some cases, it's difficult to find the correct link to open a specific site securely."

"The solution could be faster as the process is very slow."

"Security, overall, can always be improved."

"The pricing changes too fast. We get the license and we need to relicense it because they already made changes to it. We always need to be on top of the licenses because they're always changing."

"I would like to see DLP integration in the next release of this solution."

"It's somewhat pricey for us, however, it's an awesome solution."

"The integration with Cisco could be better."

More Cisco Umbrella cons

"There could be a feature to view the VPN tunnel activities in terms of configuration."

"I can't speak to any missing features."

"There could be additional ways to define proximity. Additionally, they should provide some exclusion options for specific policies and an ability to control the DLP engine."

"Zscaler Private Access needs to improve its collaboration with applications without compromising security."

"The product must allow users to check logs for an entire year in the local console."

"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."

"There is improvement in enhancing proper manageability, policies, and logs. So, log management could be improved."

"On the improvement side, when we bypass certain internet traffic types, it's currently recommended to have a one-click option, but audio and video aren't always supported. Thus, we need to bypass that kind of traffic. So, it is an area of improvement."

More Zscaler Zero Trust Exchange Platform cons

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

"It is expensive compared to one of its competitors."

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

"We were using the free version, and we implemented the paid version about two months ago. I'm paying a fair price, but everything is negotiable with Cisco. One of the benefits that I got by having Cisco Umbrella is the licensing of the Cisco AnyConnect VPN client."

"The price is fair, and the licensing cost is based on the number of users. We have seen a good ROI."

"Licensing fees are paid on a yearly basis."

"You get what you pay for if you break the solution up into tiers."

"Its price for us is quite expensive because it's a subscription, and we just use it for the DNS log. So, for us, it's quite expensive."

"I think it's worth the money."

"There is a one-time cost of approximately $800 USD per user, and then a yearly support fee of about $50 per user."

"Our costs were negotiated, and they are okay."

More Cisco Umbrella pricing and cost advice

"In the long run, cloud services are not inherently costly."

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

"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."

"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."

"It's an affordable solution"

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

"The product is a little more expensive than other tools."

"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."
