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.

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.

Simplifies management by shifting from on-premises solutions to cloud-based

Depending on the complexity of your system, you might need additional help during implementation. Considerations such as whether you’re using federated Active Directory or on-premises Active Directory need to be addressed. While setting up a system can be quick, taking only ten minutes to get started, rolling it out for an enterprise requires careful planning. Ensuring you make the right configuration choices is crucial for a successful deployment. It depends on the size of your deployment. While you can handle the setup, larger deployments might require additional support to manage effectively. I rate the initial setup an eight out of ten, where one is difficult and ten is easy.

Quotes from Members

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

Pros

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

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

"Technical support is pretty sharp and very responsive."

"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."

"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 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."

"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."

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."

"The product is easy to install and deploy on the cloud."

"I would rate my experience with the initial setup an eight out of ten, where one is difficult, and ten is easy to set up. It was pretty straightforward."

"This solution does not require much administration."

Cons

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

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

"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."

"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."

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

"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."

"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."

"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."

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."

"WSS runs slowly sometimes, I would like for this to be looked into."

"The product is cost-effective, considering its features, technology, and support services."

"Symantec Cloud Secure Web Gateway can be improved by giving customers more ability to provide feedback on the categorization of websites and the site review portal."

Pricing and Cost Advice

"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."

"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."

"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."

"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."

"The price is fixed and affordable."
