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

Pros
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering.""It does a great job of preventing spam, malware, and ransomware. I can only go by what people have told me and what I've seen, but I have not seen spam in a year and a half to two years in my own company mailbox. And there are not a lot of catches where it's catching something that should have gotten through, either.""It has the ability to tell us, after an email has been delivered, where else it went, once it got inside. Maybe it's something we wanted it to stop and it didn't stop it, but it notified us later that it was something that it should have stopped. It can give us a trajectory of all the other places that it went internally and it can tell us what files were transferred as well.""Cisco Secure Email Cloud Gateway has allowed our users to be able to concentrate on the emails that they do receive. Previously, our users had to deal with nine million additional emails across the organization, which is nearly 1,000 emails per user to have to deal with a month. That's a massive amount for our staff to deal with and probably several hours of their time. We have a lot of clinical staff, being a hospital. We want to make our staff as productive as possible. By removing a lot of that spam and phishing type emails, this allows them to do their job.""There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails.""The filtering is definitely better at catching both spam and malicious messages, and there's a lot of extremely granular ability for setting up rules. You can do it the way you want to. The Microsoft solution tends to be pretty limited in how it allows some of that to be done.""Anti-Spam and Advanced Malware Protection are the most valuable features... and we also have the option to block Zero-day attacks.""The solution is very configurable. It has enabled us to configure some specific filters to stop emails that general configurations didn't stop. It's a powerful solution. It can analyze a lot of emails simultaneously, with no problems of capacity or system load."

"The good part is that you don't have to configure it, which is very convenient.""Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links.""Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features.""At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."

"The feature that I like the best is the fingerprinting concept.""The cloud-based interface is very user-friendly.""The solution is excellent at blocking spam.""The setup is pretty simple.""It is a solid and stable product.""I like that it's simple and easy to configure, deploy, and manage. The reporting function has all the features we're looking for, and we are fine with that.""Symantec Messaging Gateway is stable and scalable. Installation is easy, and the deployment and maintenance can be done by one administrative person."

Cons
"The reporting functionality needs to be improved.""Typically, in a phishing email, they try to use a name everybody's going to recognize, like the CEO's name or the CFO's name... With this appliance, the way it's designed at the moment, for us to really stop that with any level of confidence, we have to build a dictionary of all the names of the people we want it to check, and all the ways they could be spelled. My name would be in there as Phillip Collins, Phillip D. Collins, Phillip Dean Collins, Phil Collins, Phil D. Collins. There could be eight or 10 variations of my name that we'd have to put in the dictionary. There's no artificial intelligence to say "Phil Collins" could be all these other things, and to stop phishing from coming through in that way.""I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate.""I use the search all the time. Sometimes, it is hard to search for things and things are hard to find. People come to me all the time, saying, "This email didn't get through." Then, I go searching and don't find it on the first search. You have to think about alternative searches. I don't know if there is an easier way that they could help to find things. I don't know how they could simplify it, because now everybody else is using the cloud and everything is coming from Office 365, or whatever. It is just not the same environment from years ago where everybody had their own server and you could search easier.""The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration.""The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations.""They can do it better with web links, with the URLs. They have a technology called Outbreak but it doesn't work as well as we would like.""The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."

"We need a separate license and we don't know how to get the license that is required.""There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types.""In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement.""It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."

More Microsoft Defender for Office 365 Cons »

"It will provide Excel reports and PDF reports, but it would be great if they supported the concept of Crystal Reports.""This product would benefit from better integration with Symantec Endpoint Protection.""They have updated the version of the Messaging Gateway and the new features they are adding the need to be re-evaluated. They have done some changes on the policy.""In a later release, it would be nice if the messaging gateway supported the cluster feature.""Sometimes the solution picks up false positive for viruses during scans.""What's lacking when you compare it with Proofpoint and other threat protection solutions is that it does the basic stuff, but we need more advanced threat handling.""It is a nice product but is not user friendly in terms of the graphical interface. It is poor and is not rich in terms of the human interface."

Pricing and Cost Advice
"You're going to get what you pay for. If you're not willing to pay the price of Cisco, you're not going to get a product that's as good as Cisco. I don't think Cisco is overpriced, because for the last two years I've been comparing it to Microsoft and Cisco has been cheaper and given us more features.""In my previous organization, avoiding four instances of CryptoLocker within an estimated six month period is approximately $600,000 in lost time and effort. Our five year cost was about a million dollars, and the four outages that we had equated to 65 percent of that five year cost.""The licensing was all transferred.""Compared to Cisco's on-prem service, the cost is the same, but you don't have to pay for the hardware and you don't have to maintain the system, as far as upgrades and hardware failures are concerned. It is cheaper to operate on their cloud service than it is to operate with their on-prem service.""Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco.""There are additional fees for adding features."

More Cisco Secure Email Pricing and Cost Advice »

"It's a user-base subscription.""From the pricing point of view, like any other product in the market, there is scope for negotiation."

More Microsoft Defender for Office 365 Pricing and Cost Advice »

"A subscription for technical support costs extra.""It's a bit expensive compared to its competitor Barracuda Email Security Gateway but cheaper than Sophos Email.""The cost of Symantec Messaging Gateway is too expensive in general. However, the appliance also includes the price of the license in the same bundle."
