Securing Office 365 in 3 Easy Steps

Five months is a long time in the business world—never mind five years. That’s why it’s so impressive that Microsoft’s Office 365 has consistently ranked as the #1 application in our Businesses @ Work Report. It’s now 2020, and Office 365 is still the most popular workplace app by a large margin.

Unfortunately, that success doesn’t come without risks. As Office 365 has become a fixture of modern workplaces, cybercriminals are increasingly determined to compromise it. By breaching Office 365 in one organisation, they believe they’ll open the door to hundreds of others—making the app an important threat vector to secure.

Hackers have a vast toolkit of tactics they use to breach an organisation’s networks, but phishing is the most common approach when it comes to compromising Office 365 accounts.

If Office 365 is mission-critical to your operations, it’s best to take a holistic approach to defend it. This can include disabling legacy authentication in favor of modern solutions, federating with an identity provider like Okta to enable SAML-based logins, and adopting additional measures such as SSO to eliminate the threat of bad passwords.
