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.

Prisma Access browser enhances user security with isolation but demands improvements in customer support

The best feature of the Prisma Access Browser is browser isolation. Isolation makes the user experience very good and real-time, while the container is in a different zone. This is a great feature because if phishing or something happens, it doesn't impact the user's system. The same capability is provided by Zscaler with RBI and Netskope as well. Real-time threat monitoring for the Prisma Access Browser is good. It provides good data, and the customer was very happy. As part of the feedback, Palo Alto and I collected responses from them. They haven't faced any problems or false positives. The false positive scenario is less than 1% in Palo Alto.

Quotes from Members

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

Pros

"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."

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

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

"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."

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

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

"Technical support is pretty sharp and very responsive."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

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."

"Prisma Access Browser is the most capable, advanced, and flexible product."

"Prisma Access Browser improves security because the browser is one of the attack surfaces, it needs more security on the endpoint device and standardization of device usage, and it also helps standardize the access policy to the internet."

Cons

"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."

"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."

"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."

"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."

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

"Its pricing could be better."

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

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."

"In the beginning, the solution may not be very user-friendly and could be complex."

"The maturity of the product needs improvement as the implementation is very complex."

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."

"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."

"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."

"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."
