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.

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

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

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

"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."

"Its initial setup was straightforward."

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

"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."

"iboss is among the few products providing inline filtering where no application is needed on the device."

"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

"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

"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."

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

"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."

"The dashboards for local use could be better."

"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."

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

"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. 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."

More iboss 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

"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."

"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."

"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."

"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."
