Microsoft 365 security breach

Seeing how a lot of users and companies complete their daily tasks using this software bundle, such news is disconcerting, to say the least.

Keeping our data safe is, as you can imagine, top priority and this kind of breaches can bring a lot of financial losses to the affected users or domains.

Outbound email not secure anymore

A recent study has shown that over 85% of the total organizations using Microsoft 365 had at least one email data breach in the last year. This means that, even with all the data loss prevention (DLP) protocols in place, sensitive information still got into the wrong hands.

According to Egress, the data leaks of companies and organizations that are using Microsoft 365 for their activities have reached a 67% increase since last year. Businesses that chose a different software pack only experienced a 32% increase.

This same study also indicates that 15% of the above-mentioned organizations that use Microsoft 365 have had their security breached and data stolen over 500 times, in the same time span.

Apparently, most data beaches and the most leaked information occured via the Outbound email section. Another factor that contributed to why Microsoft is in this situation is the current pandemic and the fact that a lot of people work from home now.

The constant diverting of information has, unfortunately, put a big target on everything that was shared.

Users are not pleased

Clients of said organizations are become more weary and are taking themselves extra precautions, seeing how their data is just out for grabs.

IT leaders of 28% of companies, included in the group that uses Microsoft 365, have declared that client data was the most likely type to be leaked. In the other camp, companies that use other software, the percentage is just 10%.

The truth is that standard DLP solutions are just not capable of stopping the new wave of methods with which security gets compromised nowadays. Stepping up the defense game when it comes to online data can save money and a lot of work.

There’s no denying the wide-use of Microsoft 365, as well as its effectiveness. However, client security should always be strengthened and constantly updated for the ever-changing risks we face.
