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.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Granular control for web traffic with enhanced content inspection, but support needs improvement
There are many use cases in terms of content inspection, such as having granular control for file type extensions when trying to download file types by default. It depends on the requirements, and based on that, we customize policies. We have deployed it in an Azure infrastructure, and we have…

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."
"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."
"Technical support is pretty sharp and very responsive."
"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."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"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."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"The solution is stable and reliable; there are no bugs or glitches, and it doesn't crash or freeze."
"The Large File Send feature comes in handy when you have to send fairly large attachments."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"I recommend Mimecast based on customer requirements and budget."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"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."
"We're now certain business-critical mail is perfectly protected in multiple ways."
"Mimecast has some good support services in place."
"The most valuable features of this solution are the URL database, malicious URLs, policies, and policy creation."
"The solution is scalable."
"The product is very good, and the URL filtering database is great."
"I would rate the overall solution a nine out of ten."
"The most valuable feature is the caching."
"The CPL code is the best feature of the solution."
"The content that we are getting is very good. Content caching is also supported."
"It is easy to use, and it is stable and scalable. You don't need a large team for deployment and maintenance."
 

Cons

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"The dashboards for local use could be better."
"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."
"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."
"SSL decryption: We had issues with learners using apps instead of using web browsers."
"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."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"The endpoint-type solution is an area that needs some improvement."
"The price could be better, it should be reduced."
"The interface isn't the best. How everything works on the back end is confusing."
"External security features need improvement."
"The solution is very expensive."
"They could provide a unified licensing model, including all the security features."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"It was not a good experience due to the fact that our main infrastructure had a problem for that entire time."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The platform's pricing needs improvement."
"Symantec was purchased by Broadcom and since this has happened the support has not been good. They do not find the solutions to our issues quickly."
"The product needs improvement in support services, as they are lagging and not very responsive when we raise concerns or queries, especially in terms of significant impact."
"The user interface could be improved, and the price could be lower as well."
"One area for improvement in Symantec is the lack of a reporting server or dashboard integration with SIM."
"Activating the SSL inspection is one of the challenges. We are currently moving to the O365 cloud, and one of the challenges is the performance when all of our users are connected to O365 by a proxy."
"Pricing is difficult to specify as Broadcom sells platforms that include multiple products, making it hard to determine the exact cost for the proxy component. Forcepoint sold only proxies, which was easier to measure."
"The initial setup can be somewhat complex, and deploying the system can take some time."
 

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."
"It is expensive compared to one of its competitors."
"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."
"It is probably in line with other solutions, but I do not deal with the financial side."
"The product has good pricing in terms of return on investment."
"The solution is expensive."
"The product price is moderate. I rate the pricing a five out of ten."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"It is a bit expensive."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
"The customers can select the license packages as per their requirements."
"I'm always going to say the price needs to be lower, but it's reasonable."
"Symantec Proxy has different expiry dates and renewal dates, which is a problem, so Broadcom should improve the licensing renewal process for the solution."
"The price of the solution is reasonable compared to others on the market."
"There are no licensing fees required."
"The solution is very expensive."
"It's expensive. Clients often go to other products."
