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.

Auto scanning and enhanced security but re-adding protections need improvement
At that time, we observed certain issues with the product. The functionalities could be improved, such as the isolation feature. If we remove our protection, we cannot easily add it back. If, in our organization, we need to remove a specific system for a particular time, we cannot add it back for security after doing so. This is one thing we have experienced. Scalability is also lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong.

Quotes from Members

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

Pros

"The malicious URL scanning, as well as the anti-malware features, have been really useful for us in our environment."
"Anti-Spam and Advanced Malware Protection are the most valuable features... and we also have the option to block Zero-day attacks."
"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."
"ATP has been the most valuable in improving our email security posture."
"Spam controls are excellent because they are a powerful feature that operates almost effortlessly."
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"The product blocks spam emails."
"It's a bit easy to handle Cisco Secure Email; it's not that difficult. For the logs, which are in PDF format, it's not hard to read them. We don't need Wireshark much to analyze the logs."
"The auto-scanning feature is quite beneficial."
"The auto-scanning feature is quite beneficial."
 

Cons

"I would like them to add some clustering or high availability features."
"Better dashboards and more interactive overviews would be nice, but the current functionality is sufficient."
"The tool's pricing can be improved."
"We cannot manage multiple devices from a single UI."
"We would like to see more options for the customization of content filters."
"There could be additional DLP functionality for it."
"If you are not a technical guy, it is hard to maneuver, but as soon as you work on it, it gets better and better. If there was a better way to know how to do things or how to find things, it would be good."
"The reporting functionality needs to be improved."
"The functionalities could be improved, such as the isolation feature."
"Scalability is lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong."
 

Pricing and Cost Advice

"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"The license was not per user, the license model was per feature. You could choose anti-virus, anti-spam, etc. It was feature-based and charged yearly."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"There are additional fees for adding features."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"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."
"As per market availability, this solution is more expensive than other vendors."
"We were using Proofpoint and then we switched to Cisco... reportability was one of the main reasons we switched, but the biggest one was cost. If you can get an equivalent functionality for a better price it's wise to do so. That's what our primary decision came down to: We could get equivalent functionality at a lower price point."
