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.
Mike Bulyk - PeerSpot reviewer
Can quickly identify, track, tag, and categorize internal emails. Reporting accessibly via the main dashboard would be a great addition.
If Cisco could continue to develop integrations, whether it's internal tooling, Threat Grid, or AMP reporting which could be accessible via a single web page, that would be helpful. This would essentially add additional context on messages as well as files or links being detected. Potentially adding additional context on why certain messages are tagged as spam or malware. In our case, malware hasn't been detected yet, but spam certainly has been. Knowing what engines or which components of the message make it identifiable as spam, that could be useful. Additional context and reporting accessibly via the main dashboard would be great. 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.
Andras Solt - PeerSpot reviewer
Reasonable pricing and good spam filtering but does not offer robust gatekeeping
It's mainly suited for mid-size companies, not for bigger companies like us. We are more than 1,000 people. In fact, we're over 2000 users, so that's why we investigated some other products, and Clearswift, for example. We likely won't increase usage. We're looking at GFI in a year or so.

Quotes from Members

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

Pros

"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"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 most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"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."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"This solution is easy to use."
"It has an efficient email filtering feature."
"The product offers protection, email security, anti-spam, and antivirus."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"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."
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
"The solution is stable."
"The deployment is simple and once up and running it is easy to manage."
"The number of false positives is minimal."
"I am satisfied with both the scalability and the stability of this solution."
"Troubleshooting is very simple because you can see where the email was not delivered and why it would be considered as spam."
"When combining this solution with other Fortinet products, such as FortiGate, it integrates well and provides a comprehensive protection package."
"The solution can scale."
"They have a feature called CDR, Content Disarm, Reconstruction, click protection, and DLP for encryption purposes."
"This excellent email gateway minimizes spam, inspects suspicious emails and isolates infected attachments with little administrative effort."
 

Cons

"The phishing and spam filters could use some improvement."
"Configuration at the mid-level could be improved for the support team."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"I'd like some additional features any product can give me to protect our environment in a better way."
"The solution is a bit expensive."
"We encounter issues while searching for missing emails."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"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."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"The physical appliance has been discontinued, although the platform still exists."
"The area that could use some improvement in Fortinet FortiMail is the integration process. I would like the integration to be easier."
"An additional feature that could be added is a pop-up screen notifying you that an email has been blocked, without having to double click on it to take you there it could provide you with a summary explaining why it was on hold or why was it spam when you hover over it with your cursor."
"Such kinds of things, raised from the point from the objective actually, we are using Fortinet FortiMail. We don't find any kinds of challenge or difficulties, but Fortinet FortiMail is more efficient and more effective for us. I don't know for other client, but for us, Fortinet FortiMail is very effective Like, for instance, if it is possible, let's say some kind of high threat is actually encountered if it could be possible to SMBs in our smartphone, or mobile apps, kinds of thing, if Fortinet FortiMail is available to monitor the thing using from our mobile phone from our smartphone. If such kinds of things are truly included, it will be more or good for us."
"I have little to say about possible improvements, but the configuration for content blocking could be better. So, for example, if the email includes the line "You have a Bitcoin", I would like it to be easier to block it before it enters an inbox. Fortinet could maybe offer better or simpler help on how to do this properly."
"The support could be faster because we've been receiving complaints from customers, they say that when they raise a ticket, it doesn't take 24 hours to respond, sometimes the support responds after three days. This is a lot of time."
"Improving the upgrade process, making it more user-friendly, and simplifying the management of hardware components could enhance the overall user experience and appeal of Fortinet's email security solution."
"The only drawback to this solution is that the firmware is frequently updated, and each update results in downtime."
"The biggest room for improvement would be the deployment. It will be hard for someone who doesn't understand the interface to deploy. If you understand it, you can find your way around the problems."
 

Pricing and Cost Advice

"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"I know that the product is incredibly expensive."
"The license is expensive because the cost is based on the number of users."
"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."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The product is expensive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"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."
"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"The solution’s pricing is manageable."
"Fortinet FortiMail has an annual license agreement."
"The tool is very expensive."
"We paid approximately $30,000 for the solution. It is less expensive than some other solutions. We have one license that carries all the features that we wanted."
"The fees for Fortinet FortiMail can be complicated. However, overall the pricing is fair."
"It is an expensive product."
"In the future I would like it if there's a possibility to lower the price of the bandwidth and UTM. It is quite expensive."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"The product's licensing part depends on the number of mailboxes and the hard disk needed by customers. The cost of the license depends on the number of mailboxes and the number of emails."
