Managing Director

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 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 pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."

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

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

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

"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."

"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."

More iboss pros

"The biggest return on investment when using Cisco Umbrella for me is the ease of use of the fact that we've deployed this with our Cisco VPN Secure Client, so every computer has the Umbrella module in it."

"The Secure Internet Gateway benefits my company because now our whole traffic goes to the Umbrella Cloud and it gets checked there, so nothing malicious is coming into our network."

"Cisco Talos threat intelligence significantly influences my company's ability to act against emerging threats, giving us the chance to patch our side or take precautions when zero-day vulnerabilities emerge."

"The solution is extremely stable. It has excellent performance."

"You can manage and create policies based on a group of users. It can permit some URLs and block others."

"The user interface is great. It's very easy to tailor to our client's environment and needs."

"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 will protect, give you more robustness, and faster responses, compared to any firewalls or any of the proxy web servers."

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

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

"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."

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

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

"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."

"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, obviously, there are bugs."

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

More iboss cons

"I would like for their support to be faster."

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

"The integration with Cisco could be better."

"I'd like to see this solution more closely integrate with other products Cisco has in its portfolio."

"It should have a real-time malware classification engine. It should check the malware on the website. It would be good if it had a real-time malware check for the websites because currently, it just compares the DNS queries of the blacklist. It should also have malware control over file execution and the types of files that the users are allowed to download."

"It had the ability to do a lot of app control. So, every single app that went through that portal was registered, but there is a general issue with the whole app control. As soon as you add a mobile phone to your network, all of the apps get registered through the system, and you can approve, reject, or just let them go through. When I looked at it, it was impossible to manage app control. There was just so much data. I didn't apply that service because I just didn't have the time to manage it. It would be good if there was a way to categorize applications."

"Having ready-to-go templates with best practices is definitely something that would be an improvement. Deployment, from day one, is something that definitely needs to be improved for Cisco customers."

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

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

"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."

"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."

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

"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."

"Cisco should make the solution cheaper."

"In terms of licensing, we're not able to be extremely clear with the customer because it's based on their reporting. It's not based on the actual traffic. If they say they have 50 users but they have 80, we'll just buy for 50 users. That's something where we'd like to have more flexibility."

"There are three models for licensing with different feature sets."

"We have a security Enterprise Agreement with Cisco, so the pricing is good."

"Cisco has a set price for a single license up to 100, but whenever we get over 100, we have to ask for a quote."

"I think Cisco Umbrella is priced well. We have a mix of customers with different verticals such as education. We have clients in the commercial space as well. Umbrella is at a good price point for all of our customers."

"The solution’s pricing is reasonable."

"Its value exceeds its pricing."

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."
