Freelancer Computer Software Used the software for: 2+ years ### "Microsoft Defender Review" April 22, 2021 5.0 As an individual who works from my home office, it is extremely important that my computer is running properly, so it is imperative that I have trusted security software to help me achieve that outcome. I must say, Microsoft Defender has been and is continuously essential in me doing that. Microsoft Defender has been compatible with the client systems that I have to access in order to perform my day to day business. My computer has been protected safe and protected from malware and spyware that has tried to attack my computer on several occasions! So, I can't say enough about this product, as it is one of the best on the market! Pros What I really like about this product the most is that it comes pre-installed on your Windows operating computer. I didn't have to sign up for a free trial with another security software application in order to protect my computer and then turn around and pay for a monthly subscription thereafter, upon the expiration of a free trial! Microsoft in general takes the time to considerate their customer's experience and they continued the trend with Microsoft Defender. Cons If I had to nitpick and find one thing about the software that I don't particularly like about Microsoft Defender, it would be the fact that its not compatible with some of the other computer security software applications around. You can't operate both on your computer at the same time. However, you really don't need any other protection when using Defender. Review Source MSA Mark Senyo A. Head of Department Hospital & Health Care Used the software for: 2+ years ### "A very practical solution to online threats" September 24, 2021 4.0 Our systems administrators can get a little overwhelmed and can take a while before completely onboarding new devices on all our security protocols. It is therefore assuring to know that these devices already come secure with the protection provided by Defender on Windows. Pros I like that it comes complete with the Windows and Office package I use. Therefore I get to avoid all the stress with software download and product licensing. For features, I like that it allows me to manually adjust its threat detection parameters to reduce the incidence of false alerts. Cons Since it comes so well integrated with my operating system, I have very little control over update schedules and upgrades. Sometimes, this can be a bit confusing -- not knowing how potent a recent update is or whether or not I would need secondary protection.

Dj Events Services Used the software for: 1-2 years ### ""Awsome With The Best Features"6" September 21, 2022 5.0 Overall,Defender for Office 365 is the best Microsoft. It offers quit number of software that helps you secure and test your surroundings i.e Defender Vulnerability scans, attack simulators, Alerts/Indicators ,pushing simulators. The products have help in big side of investigation big time. Pros What i like the most about the product are,custom alerts and vulnerability assessment. Custom Alerts allowed us to creat detection through KQL hence getting alerts on anthing that happens immediately. Vulnerability assessment have strengthen outdated software and aslo helps in cleaning unsafe software from our device. Cons What i least like the most about is learning curve of investigation indicators and pushing campaign operations. Learning curve of investigation indicators one feels like your just going through the same stuff and always coming back to square one problem its not that good at all at the moment. Pushing campaign function is quit slow and the major problem i have with it is that it cannot allow random templates send and it only send one ofter another. Review Source AC Alexis C.

June 16, 2021 5.0 Other than my initial compatibility issue that has been resolved, I have no complaints. Pros I love how it has multiple features that I used to use several different software for. It comes with everything that I need and I haven't had a virus since I started with it. My devices actually run more swift and the security settings are amazing. Cons I would say that when I first started with it, it wasn't compatible with everything but there are always updates and I haven't had a compatibility issue in over a year. It is constantly being updated and modernized with daily technology and software and I hope it is around for many more years, I don't know if my business would continue smoothly without it.

IT Support Analyst Mechanical or Industrial Engineering Used the software for: 2+ years ### "Defender worth the money" June 5, 2023 4.0 Pros Worth the cost - easy to setup and deploy - easy to maintain Cons Could use more features and allow the end user more permissions. Review Source Bastián M. Industrial Engenieer Civil Engineering Used the software for: 1-2 years ### "Little experience" June 22, 2021 4.0 Pros I found out about the program through my university's office 365 account, the benefits that most caught my attention were the security of passwords, the detection of malware and its blocking of spam, since with the heyday of ecommerce it is inevitable that the e-mail is filled with advertisements and commercial offers, which could be malicious. Cons What I liked the least is the difficulty in being able to access this application, the truth was I had knowledge of windows defender and I used it to keep my computer protected, when I found out that there was a version for office 365, I did not understand if its activation was automatic like the windows one or if it was a separate service, after researching about it, I had to become a windows insider user to be able to use the service. It is evident that its end customer is account administrators, however I see potential as an email account management and analysis tool, because today it is common for users to have more than one operational account, with many emails with different purposes. Although there is already the functionality to analyze threats of emails, it would be useful to unify the analysis and analyze the url addresses together with the downloadable files not only from suspicious emails, but from any origin that the user requires.

July 3, 2021 4.0 It help me to be confident when downloading files from untrusted websites, where dangerous apps or files can easily be flagged a warning sign. Pros What i like most about Microsoft defender its free for all pc with windows 7 or higher and very useful at detecting malware files, network-based attacks, and flagging phishing sites. Compared to other third parties antivirus programs where you have to pay unless you will endup using the free trials with limited features. Cons Though Microsoft defender its free, But its not 100% effective compared to other third party antivirus scanner where they are very effective and with malware detection rates are higher compared to Microsoft defender, also windows defender is not user friendly so for beginners may find it very hard to use.
