Tolu Omolaja - PeerSpot reviewer
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.

Provides comprehensive threat protection with suggestions for modernizing controls
I use the email gateway as the core of the email exchange between the Internet and our domain. The email gateway serves as the email exchanger The product offers protection, email security, anti-spam, and antivirus. It includes threat intelligence with advanced malware protection and many…

A stable product that provides security and control over spam and phishing emails
I have a lot of control over spam and phishing emails. I can monitor and manage it from Hornetsecurity’s console. The live tracking system is valuable. We can track every incoming and outgoing email live. We can decide whether to block, release, or quarantine emails. We can also review the emails before releasing them. The product provides 99.9% coverage for email security.

Quotes from Members

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

Pros

"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"Scalability-wise, I do not think there are any issues so far."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"Defender helps us prioritize threats across our organization."
"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"I highly recommend it as one of the best choices."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"It's very easy to deploy and configure."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"The solution is stable."
"The best part is, I rarely have to access the portal as everything is set up and tweaked the way I wanted it. But the feature set is incredibly granular and allows for deep levels of customization."
"I have a lot of control over spam and phishing emails."
"Hornetsecurity 365 Total Protection is an easy-to-use solution."
"Backup and restore are precious features."
 

Cons

"The GUI is sometimes slow to fetch the device report and could be improved."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"Configuration at the mid-level could be improved for the support team."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"The pricing could always be better."
"The physical appliance has been discontinued, although the platform still exists."
"The solution is a bit expensive."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"The solution’s pricing is not reasonable."
"A reduction of 10% in pricing can be an improvement."
"I guess I would say maybe quick access to training material for end-users. I know partners have access to this but I as an end-user do not have immediate access to new update information."
"The pricing is a little high compared to other products."
 

Pricing and Cost Advice

"I was working in the government and it was too expensive for us to use our Microsoft products."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"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."
"I know that the product is incredibly expensive."
"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."
"The pricing is normal. Considering its popularity, it's not overpriced."
"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."
"The product is very expensive."
"The feedback from vendors and customer is that it is expensive."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The solution’s pricing is manageable."
"It is expensive compared to other vendors."
"The pricing is acceptable and falls into the medium range, neither cheap nor overly expensive."
