Provides good visibility into the traffic, valuable reporting, and secure remote access
A lot of our customers use another Cisco product already, so they have confidence in Cisco products. The firewalls they are currently deploying and using have evolved from their older ASA products. They are now moving to the new Firepower Threat Defense, which incorporates many more features and allows them to get the latest ALOFT download and feeds for any security vulnerabilities and they're able to react very quickly to any vulnerabilities that have been highlighted. Initially, when the firewalls were first marketed and came onto the market, the visibility wasn't very good. But as the software evolved over time, that visibility has increased a lot more, and that is giving customers a lot more competence in the traffic and the traffic flows that they're seeing through the actual devices, so they can better understand the types of applications that they have on their network. The good thing about the actual firewall itself is that it can integrate with other Cisco products, such as Cisco ISE so that it allows full end-to-end visibility of connectivity. It gives very good visibility. It's that integration with other products, not just what that individual firewall can do itself. Talos is obviously fundamental to the actual firewall, reporting on vulnerabilities that are happening day to day. And the regular downloads, obviously, give customers confidence that their products are as secure as they can actually be.

Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

Quotes from Members

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

Pros

"The logs are easily readable and help diagnose problems, although they can be difficult to find initially. The solution addresses our email security, but for the rest of our security, we would use multiple vendors. It covers everything through email, like antivirus, IDS, and IPS."
"Initially, the most valuable feature for us was the SenderBase Reputation, because that reduced the number of emails that were even considered by the system by a huge number..."
"The product's initial setup phase was easy."
"The tech engineers are very knowledgeable."
"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."
"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."
"The technical support from Cisco is perfect."
"The tool has a DLP solution which we can implement. Its database is updated regularly."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
 

Cons

"The solution does not have a strong outbound service. It should also integrate DLP."
"The user interface needs some improvement to become more user-friendly. The graphics could be better. It's designed more for a technical user rather than a business user."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"The discontinuation of physical hardware solutions is a significant area for improvement in Cisco Email Security Appliance. This decision has posed challenges as virtual appliances are now the only option, which may not be suitable for all industries. The uncertainty regarding the future of the hardware aspect of the solution is a notable concern."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well."
"I would like to see features like AI since it is currently an area that the product lacks."
"The user interface could be updated."
"FTP server and TRUST Manager functionality."
"Malware needs improvement."
 

Pricing and Cost Advice

"In addition to the standard licensing, there is a cost for SMARTnet as well."
"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."
"At times, we feel the pricing is a bit too high, but then, there is also room for discounts. We enjoy a lot of discounts, and that is why we are still with them. There are no costs in addition to the standard licensing fees."
"It is a reasonably priced solution."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"The product's price falls on the higher side when compared to the other products on the market."
"It is an expensive product. I rate its pricing an eight or nine."
"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."
