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 Engineer at Logic Infosecurity
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.
KK
Principal Consultant at CSaaS
Monitors traffic effectively but struggles with integration challenges
I find that the technical support is mediocre, at least for the Middle East. I frequently face challenges when contacting OpenStack through the distribution channel. It should be more straightforward. I notice that customers work with partners, not directly with Symantec, relying on local company integrators for support. Symantec becomes the level two or level three support, which requires navigating through a supply chain that is quite extensive.

Quotes from Members

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

Pros

"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."
"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."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"The iboss solution gives me the ability to scan the traffic through all the ports, through all the 131,000 PCP and UDP ports, and with this ability, we have the granularity also for consults over social media and applications on mobile, and this is an advantage that the customers are looking for right now."
"It was a very easy product to install. It can be deployed very fast."
"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 console is cloud-based, which is something I really appreciate."
"In terms of technical superiority and the product itself, there are no complaints."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"We used Mimecast Mailbox Continuity when we had a power issue, and it works, has been pretty reliable, and the support has been quite good."
"It is our spam filter, phishing filter, and executive impersonation filter."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"I have been satisfied with Mimecast Email Security as a good solution."
"The solution is pretty straightforward to use and easy to set up."
"I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues."
"The most valuable feature is the endpoint security."
"Overall, this product is okay and it does the job that it is supposed to do."
"It is a stable solution."
"The most valuable features are the website blocking capability and SSL interception."
"It's nice to have it in the cloud where we can pull the reporting together for it so we can see what's happening in machines at different locations."
"As a proxy, there are many features available that benefit the customers, including caching, the security appliance, the cloud of service, and many other features."
"It is easy to manage, the graphical user interface is quite easy to navigate, and we don't have any difficulty in using it."
"It offers an easy initial setup."
 

Cons

"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."
"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."
"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 within the reporter to navigate directly to the content the user is traversing."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"The reporting feature needs improvement."
"Its pricing could be better."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"The solution is expensive in comparison to similar solutions."
"External security features need improvement."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."
"The attachment scanning feature doesn't work properly."
"The price of the solution is expensive. It can improve by reducing the price."
"Depending on the severity of the issue, I think they can be a bit slow - a few days for the low severity cases, but for the severe cases normally they contact you back in a couple of hours."
"AI-driven security could be helpful, yet how effective it will be remains unclear."
"Difficult and time-consuming to deploy and update."
"One of the problems with using Symantec is that it's widely known and the people who are making malware have designed to circumvent it."
"The cost has risen and it is more expensive than it used to be."
"One of the problems with using Symantec is that it's widely known and the people who are making malware have designed to circumvent it."
"I find that the technical support is mediocre, at least for the Middle East. I frequently face challenges when contacting OpenStack through the distribution channel."
"The major challenge is their support. The support from Broadcom is quite poor. It takes forever for them to get back to you, and when they get back to you, they ask you for so much information, which makes it more difficult. That's the only problem I have with Broadcom. This is one of the reasons why we are switching to another solution. Another reason for switching is that we have a plan to adopt solutions in the cloud so that we can offload the administration efforts to the vendor. In future releases, they can improve its reporting and the process for rules creation. They can also improve Broadcom on things such as security information and event management so that from my same platform, I can carry out functions and probably block websites. Such a feature would be nice. Currently, Broadcom is integrated with McAfee to block access to certain sites automatically. It would be nice if they can expand their integration to IBM Resilient Security Orchestration and Automation Response."
 

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."
"It is expensive compared to one of its competitors."
"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."
"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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"The product has good pricing in terms of return on investment."
"The product price is moderate. I rate the pricing a five out of ten."
"The price of Mimecast Mailbox Continuity is expensive."
"The licensing costs are per-user for the product that you get with them."
"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."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"The solution is expensive."
"Pricing and licensing is stunted and licensing is expensive. We have many customers who are now thinking about other solutions due to the cost."
"There is an additional charge for advanced security features."
"Symantec Secure Web Gateway is less expensive than one of its competitors."
