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.

IT Manager at a logistics company with 201-500 employees

Email security has protected critical communication but hyperlink handling still needs improvement

We have been using Mimecast Web Security for quite a lot of years. Regarding the analytics part you asked and what metrics are most valuable for monitoring web activities in our case, we am not dealing with the monitoring; that's our MSP who does the majority of the monitoring on our behalf. Regarding the reporting part, I have seen the original reports from Mimecast Web Security, which seem to be quite heavy in terms of information. With the MSP, we are just reviewing and discussing what is necessary. If there is a concern, that is dealt with MSP immediately rather than waiting for formal conversations. However, I think the Mimecast report is fine and easy to read. It is hard for me to say whether the installation is easy or complex, as I wasn't involved; it was done by our MSP. I am the end customer of Mimecast Web Security, not a consultant.

Quotes from Members

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

Pros

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."

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

"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."

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

"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."

"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."

More iboss pros

"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."

"The customer experience is very good, and the product improves security posture."

"Cisco Umbrella offers DNS layer security, a secure web gateway, and cloud access security broker functionality."

"It's very stable, reliable and does its job."

"I like the original functionality, which allows for providing secure DNS services."

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

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

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

More Cisco Umbrella pros

"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."

Cons

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

"The reporting feature needs improvement."

"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."

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

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

"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."

"Sometimes, obviously, there are bugs."

"The dashboards for local use could be better."

More iboss cons

"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."

"It is a value for money product for sure. However, it does not have that kind of awareness plus brand within the customer, as they are influenced more by brands such as Palo Alto or Fortinet."

"In my experience with Umbrella support, sometimes the response times take a bit more time than we would like... sometimes, if you go through email, it can take quite a while to get a response."

"There are a couple of different pieces that have different portals. I know they're working on getting them all into one portal, but that's probably the biggest thing that needs improvement right now. It's not a single pane of glass yet."

"Data reporting could be improved."

"There are cheaper solutions in the market"

"The channel of support needs improvement. It is not under normal Cisco support, and I cannot simply call for support."

"The main issue that we have is with the final steps or the full integration and getting rid of Zscaler. The company still has to fall back to Zscaler when something in Umbrella is not working as expected, such as when we enable SSL inspection. When something is not working 100%, the company is falling back to Zscaler."

More Cisco Umbrella cons

"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."

"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."

Pricing and Cost Advice

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

"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."

"The solution’s pricing is reasonable."

"The price of Cisco Umbrella is a little higher than similar solutions, like Gateway."

"When talking about Cisco solutions in general there pricing model is horrible. For example, you can sell a Meraki-based solution, but if the customer starts shopping around, someone is going to have access to the pricing at a level that you cannot compete because they do not have uniform pricing. Not everybody gets fair pricing. Unless you are one of the real major corporations selling the solution your ability to compete is impossible. Cisco will acknowledge the situation and assure you next time it will be in your favor but it never becomes favorable for you. Cisco is not very good in this regard. However, Umbrella is good."

"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."

"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."

"Pricing depends on the automation requirements of the organization."

"The pricing model is easier compared to some of the other solutions, and it is also competitive."

"The licensing fee is paid on a yearly basis."

More Cisco Umbrella pricing and cost advice

"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
