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.

Saved us a big deal by catching malicious links and attachments sent directly to our staff and has also been helpful for educating our staff
It has helped immensely because it has gotten rid of malicious links and malicious attachments that have been targeted at our different staff members. It has definitely protected us on more than one occasion. Their integrated approach of combining email security and employee awareness training is excellent because the training is a reminder for staff to continually be on their feet and look out for the ever-changing landscape. It also lets us know who has been trained, who hasn't been trained, and what they're like. It integrates a risk ratio for all our employees. Its artificial intelligence and machine learning capabilities are very important because I don't want to have to manage 24/7. Having the AI to do a lot of the work for me is invaluable. Its automated detection and response capabilities are excellent. It does a wonderful job. They provide all the stats on what it has done. It gives you information about how much time is saved and all that kind of good information. Its automated detection and response capabilities have massively decreased the time we spend manually reviewing email events. Since May, it has taken care of 170 hours. So, it has saved 88 hours per analyst. It is very good in terms of the customization of the automated detection and response capabilities. It is granular, and you can adjust it however you want. If it is too high, you can turn it down. If it is too low, you can turn it up.
