Also of the approximately 24 billion security signals that the company obtains per day from the cloud, the extremes and the intelligent edge.

From all this data, the report concludes that Microsoft Defender for Office 365 blocked more than 35.7 billion phishing emails and other harmful attack attempts, targeting both consumers and businesses, throughout 2021. In addition, Defender for Endpoint blocked more than 9.6 billion malware attacks, and Azure Active Directory detected and blocked more than 25.6 billion attempts to hijack enterprise customer accounts through brute force.

The report suggests that many of these attacks come from attackers promoted and supported by governments from different countries. In fact, attacks from these types of groups are on the rise.

This is due to the fact that there are still companies and consumers that continue to manage their credentials poorly, and that, for example, do not activate two or more factor authentication. As long as they do not take precautions like this, these types of groups will not need to change their modus operandi, and will continue to have facilities to attack.

However, it is not the only access management measure that companies should use. For Microsoft, they should also use antivirus solutions, zero-trust network access systems and firewalls.
