Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Helps prevent security breaches but fails to improve in the area of AI
I have not noticed any impressive advanced threat protection mechanisms in the tool. I don't know if there are any AI features in the product. I don't know if there is any other technology embedded in the solution. Cisco Secure Email successfully mitigated potential email threats. My company has seen plenty of scenarios where Cisco Secure Email successfully mitigated potential email threats, spam emails, and fraudulent domains. The product is good for dealing with spam emails, and it can take care of more than 100 spam emails per day. A huge number of spam emails are monitored with the help of Cisco Secure Email. I would not recommend the product to other businesses because you need to have some kind of expertise in configuring and knowing a bit about the tool's GUI. The tool also lacks in the area of AI mechanics. If I would like to have an overview and review another solution, I would go for another product other than Cisco Secure Email. I can definitely suggest others to look at the product and review it, but I would also recommend that they compare it with the other solutions in the market. I wouldn't prioritize Cisco Secure Email over other tools. Either the support partner of the product or I take care of the tool's maintenance phase by looking into the configurations and doing some fine-tuning. I rate the tool a seven to eight out of ten.

Handles security, malware and spam of email systems
We use Email Security Gateway on email systems for handling security, malware, and spam.  The solution is easier to manage than FortiMail. You can implement policies easily.  The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very…

Quotes from Members

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

Pros

"There are several features that I consider valuable."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"The email protection is excellent, especially in terms of anti-phishing policies."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"The good part is that you don't have to configure it, which is very convenient."
"Defender helps us prioritize threats across our organization."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"The most valuable features are protection against ransomware and spam."
"It sends us reports, where we can see if there have been attacks, e.g. DDoS. If so, we can switch to a clean IP."
"At one point, there was a zero-day attack. The Cisco appliance detected it and stopped it, helping us out. We avoided the attack and potential damage."
"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"It is doing its work. It is doing what it was actually designed to do. It has ensured we don't have business email compromises, and it has also ensured that our brand Galaxy is unique all year round."
"It integrates with Active Directory and we can limit specific users to using specific applications."
"The security features are valuable."
"We like the in-built features, like the email filtering based on the IP and domain. Cisco has its own blacklisted domains and IPs, which is very good. This filters around 70 percent of emails from spam, and we are seeing fewer false positives with this."
"The solution is easier to manage than FortiMail. You can implement policies easily."
"It helps reduce spam and phishing attacks."
 

Cons

"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"You should be able to deploy Defender for every subscription without the need to add servers."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"Configuration at the mid-level could be improved for the support team."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"There is a different console for different things; I just want one consolidated console."
"I am not satisfied with the solution's reporting and logging."
"In future releases, I would like to see two main improvements come to mind. First, the current solution requires maintaining two separate operating systems for FTD, which can be cumbersome. I'd love to see a single operating system for the FTD box."
"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."
"They could improve the filters. In my time at the company, there were several times we had to contact support to update the filters."
"While Cisco offers excellent solutions and innovations, the pricing may not be suitable for everyone. The cost of the software is relatively high. In the current market, there are numerous competitive alternatives that focus on security, enterprise networks, and various other aspects. Cisco, being a comprehensive provider, extends its expertise across data, servers, storage, and security, making them a preferred choice for many enterprises. However, when it comes specifically to security solutions, there are other vendors that specialize solely in this domain, offering competitive options."
"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."
"I would like to see features like AI since it is currently an area that the product lacks."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
"Its pricing could be affordable."
 

Pricing and Cost Advice

"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"The pricing has become expensive."
"The license is expensive because the cost is based on the number of users."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"Cisco Secure Email is more expensive than other products. I rate it a five out of ten. There are no additional costs. You only need to pay the subscription amounts."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"The solution is expensive."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"It is a reasonably priced solution."
"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."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"The licensing was all transferred."
"Email Security Gateway's pricing is good."
