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 internet navigation safety and boosts productivity

The features of Cisco Umbrella I prefer most are DNS protection and traffic redirect. With Cisco Talos's threat intelligence, we reduce the impact of malware traffic in our network, and we currently see the behavior of equipment and choose the correct sites. Cisco Talos has helped us reduce the impact of malware traffic. We can see the behavior and choose the correct sites. We're currently testing secure access with Umbrella in order to secure access to core applications. It's a product that the user doesn't even know is there, even though it is protecting them. It's not hard on the equipment. And, for us, it centralizes everything, which improves productivity. With the Experience Insights feature of Cisco Secure Access, we've seen impacts on the management of user connectivity by allowing us to deliver safe connectivity. We are testing the Secure Access product with Cisco Umbrella to improve our connectivity with our users in order to secure access to the corporate applications. Cisco Umbrella is in the cloud, which is nice.

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

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

"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."

"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."

"Content filtering is the most useful feature of iboss."

"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."

"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."

"Its initial setup was straightforward."

More iboss pros

"The most valuable features are the protection against ransomware and phishing."

"The most valuable feature is its ability to detect if a URL has malware or is vulnerable."

"Cisco Umbrella is the first layer of security that protects me while surfing the net, identifying untrusted websites to prevent access."

"The customer service and technical support of Cisco Umbrella are great."

"Cisco's support is fantastic, providing assistance when needed, especially during the initial installation process."

"The integration features within, for example, the Cisco VPN product and the Umbrella module are valuable."

"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."

"We run a real lean networking team, and cloud deployments are super easy."

More Cisco Umbrella pros

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

"I find all Zscaler Private Access features valuable because each replaces flawed technologies, such as EPAs being replacements for VPN and PR as a replacement for PAM, so I can't mention only one valuable feature. Overall, Zscaler Private Access is a good solution."

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

"The product provides a seamless user experience."

"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 UI is easy to use."

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

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

More Zscaler Zero Trust Exchange Platform pros

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 dashboards for local use could be better."

"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."

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

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

"Sometimes, obviously, there are bugs."

"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."

More iboss cons

"It has happened in the past that Cisco Umbrella has denied us access to secure websites."

"I would like to see more integrations with more products. Some of the integrations need to be simpler as well. For example, the integration with Cisco Secure Firewall could be simpler. It would be good to make reporting simpler. For those who don't use SecureX, it would be good to make Umbrella really simple to use upfront. It's not a difficult product, but it can be daunting for someone who isn't exposed to it because there are so many options."

"Its DNS service does not support IPv6 query."

"I feel that the application needs other characteristics that are available with other applications in the market."

"There are some situations where we would like to block things for specific user groups. I know that Umbrella does that, but it's not that easy.... when you want a specific task for specific rules and policies for user groups, you have to go three levels down in the menu, and it's hard to find where you do that task."

"Although Cisco Umbrella has an excellent global network footprint, there is still room for improvement and growth in this area. Additionally, there are bandwidth limitations associated with the connectors that need to be addressed. To be a viable solution for larger offices, Cisco Umbrella must continue to expand and improve its capabilities in these areas."

"Cisco Umbrella can be improved in terms of limited coverage and wind vulnerability."

"I would like to see more integration between Cisco Umbrella and Cisco DNA Center."

More Cisco Umbrella cons

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

"An area for improvement would be the ease of configuration."

"The solution's granularity should be improved because it has limited granular options to control, visible, allow, block, delay, and receive."

"Having a Zscaler-specific device could streamline this process and provide a more consistent user experience across diverse branches."

"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."

"Another area of improvement is implementation through non-client connectors. The solution can be implemented in two ways. One uses the back file; the other one uses client connectors. So the client connector is pretty fast, but when it comes to non-client connectors and procedures, it's kind of delayed and slow."

"I rate it a seven because I am still working through some kinks from a performance and a support perspective."

"The tool must provide IP-blocking features."

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."

"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 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 expensive compared to one of its competitors."

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

"The licensing and pricing structure of Cisco Umbrella is in line with standard systems on the market, and we have no specific requirements in this area. Overall, we have found it to be an acceptable pricing model for our organization."

"Cisco is expensive. For example, we are looking at Nexus Dashboard, and it's costing about 250,000 euros. I ask, "What do I get from it?" I'm still not convinced that we have to spend on it, so pricing is a problem."

"The pricing is pretty fair. It's good."

"You can request an evaluation license."

"The price is quite good."

"Cisco Umbrella is expensive and could be cheaper."

"The price could be lower."

"There is room for improvement when it comes to the cost."

More Cisco Umbrella pricing and cost advice

"The solution is expensive."

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

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

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

"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 is a bit expensive."

"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 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."
