And that saves us time spent downloading .apk files and installing them. Also, updates and upgrades are mostly automated and do not require any additional time spent to carry them out. These are all great benefits Defender provides at zero cost to us, so I can't not love it regardless of its few flaws. Pros the best thing about Defender is that it comes at zero additional costs for full protection and product functionality. The spam detection and filtering mechanism allows for manual readjustments to permanently address cases of mislabeling and false alarms. The advanced parental control guidance it provides is also quite effective in it's range of custom adjustments to suit each potential user. Cons Scanning local drives can be painfully slow especially for huge file counts, even if the size of the scanned documents are tiny. They also fail to recognize certain low level threats that are easily detected by others. Reason for choosing Microsoft Defender for Office 365 Defender was the cheaper option.
