Threat intelligence with fast attack detection enables comprehensive email protection
In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam. This could result in users not opening genuine emails. We have highlighted this to Cisco because sometimes phishing or marketing campaigns, which are genuine, are incorrectly flagged as spam. The solution should better analyze the actual content rather than only focusing on the email header or origin.

Helpful support, and useful dashboards
They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward. I haven't tried it in a while since then. Since I can't turn it off on a per-user basis, I had to turn it off globally. I have certain exceptions for not doing the sanitization, and how to set those up is not intuitive. It would be useful if there were a better way of doing that. Using digital certificates is hard. It would be better if it used Windows Servers' built-in certificate management.

Quotes from Members

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

Pros

"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"The solution works well."
"This solution provides some benefits, like comfortable access to TAC support. You get prompt support when working directly with Cisco."
"Spam controls are excellent because they are a powerful feature that operates almost effortlessly."
"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."
"Cisco Secure Email has strong inbound services."
"Users were able to do a check by themselves on quarantined emails. They could check if a valid email had been stopped, if it matched up with the SPF certification."
"The tool comes with AI features. It is good for clients who already use Cisco products due to integration."
"The most valuable feature of MetaDefender Email Security is the CDR. Customers purchase this solution specifically for data communication, as the other features can be obtained through other technologies that most customers already possess. Therefore, data communication serves as the foundation for the platform."
"The sanitization is very good."
"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."
 

Cons

"We have Microsoft and we have the E5 licenses, they have more EDR responses on certain emails. That's something that Cisco ESA on the cloud doesn't have. They don't do anything about MITRE attacks. They only detect if there is a malicious email or a threat and they remove it."
"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."
"Better dashboards and more interactive overviews would be nice, but the current functionality is sufficient."
"The solution needs to improve its advanced phishing filters. It is very good at filtering things which have bad reputations. However, when phishing or malicious emails are new or coming from a legitimate source, we don't feel that the solution is working."
"The management features of the product are not up to date."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"I am not satisfied with the solution's reporting and logging."
"The reporting functionality needs to be improved."
"Although the number of AV engines is good, it could be better."
"They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward."
"The DLP should be upgraded and has room for improvement."
 

Pricing and Cost Advice

"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."
"It's adapted to the market. It's similar to other vendors. We at least don't have many problems regarding that because Cisco is adaptable on that side. When we present the solutions to the customers, we tend to achieve the goals that the customer has in terms of the budget for such implementations."
"I rate the pricing a ten out of ten on a scale where one means it is less cost-effective, and ten means it is the most cost-effective solution."
"It is a super big router that costs a few hundred thousand dollars."
"There are additional fees for adding features."
"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."
"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."
"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
