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.

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."

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

"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."

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

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

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

More iboss pros

"The best possible thing is that it is very easy to deploy, easy to configure, and very fast to get onboarded with a customer because this is a cloud-based service."

"The most valuable aspect is that it is hosted with Cisco and can detect any new anomalies, acting almost like an XDR."

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

"The most valuable feature is that it secures our network against blacklisted or malicious websites."

"The documentation is good, and we have been able to resolve any issues ourselves."

"What we like most is security and how easy it is to integrate with other appliances."

"Helps block personal email accounts."

"It analyzes the domain security helps us implement the securest policy."

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

"With SASE, we have a single platform that covers multiple task services with which we need to control access. All the features are equally valuable."

"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."

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

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

"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."

"Zscaler CASB's latency and architecture are excellent."

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."

"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 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."

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

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."

"File integrity monitoring would be very advantageous as an additional feature."

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

"The reporting feature needs improvement."

More iboss cons

"If we're trying to deploy it to a Mac through Meraki, it's impossible. The method of deployment for a Mac, and the features available in Meraki, are not compatible at all."

"They should provide more integrations and bring things together so that there is a more standard feel to their platform. We also use Cisco ISE, and it has a very different feel from Cisco Umbrella."

"There is room for improvement in the dashboard. It could stand to be a bit more detailed. I would also like to be able to customize the dashboard to focus more on what is important for my company."

"Its DNS service does not support IPv6 query."

"We would like to see the enhancements made to the EDR, as we see features that are running endpoint management."

"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."

"The rule-making process for blocking sites or for blocking characteristics can use some simplification."

"Data reporting could be improved."

More Cisco Umbrella cons

"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."

"The interface needs a bit of work."

"We faced certain migration and implementation challenges in executing the tasks, so I would suggest improvement related to the stability of the solution."

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

"We'd like to have two-factor authentication that is quite simple."

"We would like to extend the SASE applications for Zscaler."

"User management can be improved."

"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."

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 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."

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

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

"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."

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

"The price is quite good."

"Cisco should make the solution cheaper."

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

"The solution’s pricing is reasonable."

"I am not sure, I don't have the numbers in front of me, but I think it's $1.00 or so per device/month."

"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."

More Cisco Umbrella pricing and cost advice

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

"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."

"Zscaler CASB is an expensive 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."

"The solution is 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."

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

"The product has reasonable pricing."
