Don't really need any other anti-virus. > > **Inconvénients**: The instructions are not very clear. It takes a while to figure out what's what and the various modules have very slight or no explanations. I haven't been able to find any way to contact direct customer support with a real person. > > It works in the background so I'm never really aware of it. A few years back I had some false positives, but not for a long time. I use Malwarebytes as well and that gives me a lot of false positives which can be a real nuisance. ----- ### "Effective protection w/ natural integration" — 5.0/5 > **Adam** | *28 septembre 2026* | Services et technologies de l'information | Taux de recommandation : 10.0/10 > > **Avantages**: Built into Windows, this is far superior from older built in security and we are switching our corporate systems to run on it which is a measure of confidence. It largely runs in the background but onopening the settings, quick security scans can be run on demand, and more information is avaialble to view. Integration into the MS environment is the main strength. > > **Inconvénients**: The administrator portal contains a large number of policies, reports and configuration options, which can make it difficult for less experienced administrators to find the correct setting. Initial configuration and policy tuning require specialist knowledge. Occasional false positives can also result in legitimate messages being quarantined in my expereicne, so the reporting and release process needs to remain clear and efficient. > > I trust this program to give me effective protection against phishing, malicious links, unsafe attachments and other threats across the Microsoft 365 environment. It largely operates in the background, providing strong security without causing a nuisance to everyday work. As I mentioned, our organisation is now moving more of its corporate environment onto Microsoft’s security platform, which is a strong measure of the confidence the business has developed in its effectiveness and wider integration capabilities. ----- ### "Strong Email Security with Excellent Microsoft 365 Integration" — 4.0/5 > **Josh** | *26 juillet 2026* | Services et technologies de l'information | Taux de recommandation : 8.0/10 > > **Avantages**: Microsoft Defender for Office 365 provides excellent protection against phishing, spam, malware, and other email-based threats. As it is tightly integrated with Microsoft 365, deployment and management are straightforward, and it works seamlessly alongside the wider Microsoft security ecosystem. One of the biggest advantages is the visibility it provides into threats, allowing administrators to investigate emails, review detections, and take action quickly. Features such as Safe Links, Safe Attachments, anti-phishing policies, and automated remediation help reduce risk while requiring minimal ongoing administration. The platform also integrates well with other Microsoft security products, making it a strong choice for organisations already invested in Microsoft 365. From a value for money perspective, it delivers significant security benefits without requiring additional third-party email security platforms in many environments. > > **Inconvénients**: The learning curve can be steep, particularly when navigating the various security portals, policies, reports, and alerting options. New administrators may find it takes time to understand where settings and investigations are located. There can also be occasional false positives or legitimate emails being quarantined, requiring review and adjustment of policies. Some reporting and troubleshooting workflows could be more intuitive, especially when tracking why a specific email was blocked or filtered. > > Our overall experience with Microsoft Defender for Office 365 has been very positive. It has significantly improved email security by reducing spam, phishing attempts, and malicious attachments reaching users. The integration with Microsoft 365 makes deployment and management straightforward, while the wide range of security features provides strong protection against modern threats. The platform offers good value for money, particularly for organisations already using Microsoft 365, as it enhances security without introducing another separate management platform. Customer support has generally been satisfactory when required, although many issues can often be resolved using Microsoft's extensive documentation and built-in reporting tools. While there is a learning curve and occasional false positives to manage, the overall level of protection, automation, and visibility makes it an excellent email security solution that we would recommend to organisations of all sizes. ----- ### "I hope Microsoft really focuses more on this software again." — 2.0/5 > **Heather** | *9 juin 2022* | Services financiers | Taux de recommandation : 1.0/10 > > **Avantages**: What I like most about this software is how inexpensive it is. When you buy a new computer that has Microsoft Windows on it, it is already ready to go for the user to use. > > **Inconvénients**: What I like least is this product worked for a while but now it is back to not feeling safe when it is running. You really have to really look into this software because you have to put some effort into it. ----- ### "Microsoft Defender is the best defender" — 5.0/5 > **Brooke** | *21 juin 2026* | Gestion de l'enseignement | Taux de recommandation : 10.0/10 > > **Avantages**: There is little to no learning curve. The setup, email and scan is very easily accessible. It helps to block out spam mail and malicious spam. Customer support is fast and efficient. Due to the high protection of the software, it is value for money. > > **Inconvénients**: I have yet to experience any bugs or issues with the software. I still utilize this software today and have for 2 years. > > Microsoft Defender has kept my Microsoft 365 programs from being attacked by malicious or suspicious spam. ----- Page : 1/11\ Suivant: [Page suivante](https://fr.capterra.ca/software/219685/microsoft-defender-for-office-365?page=2) ## Liens - [Afficher sur Capterra](https://fr.capterra.ca/software/219685/microsoft-defender-for-office-365) ## Cette page est disponible dans les langues suivantes. | Langue | URL | | de | | | de-AT | | | de-CH | | | en | | | en-AE | | | en-AU | | | en-CA | | | en-GB | | | en-IE | | | en-IL | | | en-IN | | | en-NZ | | | en-SG | | | en-ZA | | | fr | | | fr-BE | | | fr-CA | | | fr-LU | | ----- ## Données structurées
