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.

Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.
Carlos Alam Hernandez Baruch - PeerSpot reviewer
The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.

Quotes from Members

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

Pros

"The stability of Microsoft Defender for Office 365 is fantastic."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"Microsoft Defender for Office 365 is a stable solution."
"If we look at four to five years ago, we had close to six or eight people click a link in an email per month. Now, we are probably down to about five or six clicks a year, if not less."
"Email encryption enhances end to end security of any data before it passes through the networking system."
"This technology is one of Check Point's acquisitions, and it is currently a powerful tool that provides all the protection that is not found in other tools."
"It can retract unsafe emails and remove them from the entire communication channel."
"Email Attachment Protection detects any insecure files and quickly blocks them to prevent the spread of viruses to other secure documents."
"The threat detection tools enable us to ascertain malware and phishing messages across the email network infrastructure."
"I like Avanan's SmartDLP module. It's seamless, and the administrative overhead is low. We aren't a very sophisticated operation. We just want to reduce our exposure, so we find ThreatCloud helpful. Avanan's acquisition by Check Point was beneficial for them."
"When we don't understand some functionalities, the customer support staff responds fast to our calls and provides immediate action."
"Cloudflare is simple to use."
"This solution is easy to understand and easy to configure."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Enables me to work from two locations."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare is by far the most effective solution that I have come across."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
 

Cons

"The pre-sales cost calculations could be more transparent."
"The XDR dashboard has room for improvement."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"The custom alerts have to improve a lot."
"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."
"We need to be able to whitelist data at the backend."
"Microsoft Defender for Office 365 should be more proactive."
"In Avanan, the email channel is one of the channels where data leakage happens, and they need to consider it from a DLP perspective."
"It should reduce the amount of time needed for thorough scanning."
"The system response in a slow computing device affects performance when sending and receiving emails."
"Familiarization with performance for new teams may take a long time."
"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"Integration with various SaaS offerings, who are leading in the SaaS market."
"It should also offer a quick backup in case any email is wrongly quarantined or deleted to ensure no data loss."
"The customer service team could come up with clear tutorials on how to use this platform to help new teams."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"For the topic of improvement, providing some training material is one of my suggestions."
"The initial onboarding was causing us some confusion."
"Lacks a VPN feature to provide a secure connection to the data center."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"They don't have a person to provide support for customers using the solution under their free plan."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced."
 

Pricing and Cost Advice

"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 product is very expensive."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"It's a user-base subscription."
"The pricing has become expensive."
"The product is not the cheapest in the market."
"The pricing of Avanan is reasonable."
"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does.
