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

"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 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."

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

"The console is cloud-based, which is something I really appreciate."

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

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

"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."

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."

"This solution does not require much administration."

"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."

Cons

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

"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."

"The reporting feature needs improvement."

"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."

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

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

"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."

"File integrity monitoring would be very advantageous as an additional feature."

More iboss cons

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

"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."

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

"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."

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

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."

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

"It is expensive compared to one of its competitors."

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

"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."

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"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."
