Three Wins for Improving Office 365 Security

Home / Industry Insight / Three Wins for Improving Office 365 Security

Office 365 security is not something that should be taken lightly. However, with thousands of businesses turning towards the productivity and technology giant for online email, file sharing, collaboration and more, IT leaders are scrambling for some quick wins to keep their business safe and secure. Below, we discuss three relatively quick wins that you can put in place to improve Office 365 security.

Spoof Protection

One problematic issue relating to your email is when cyber criminals send emails that appear to be coming from your business, which is known as spoofing. However, within Office 365, there are several settings that can be configured and enabled which will help stop this from happening. One thing that can be done is to enable DMARC for your business domain. DMARC stands for Domain-based Message Authentication, Reporting, and Conformance, and reduces email SPAM by detecting a spoofed message, which can drastically lower phishing attempts.

Multi-factor Authentication

Another must have for improving Office 365 security is enabling multi-factor authentication (MFA). MFA requires users to have a token, verify a login on their mobile device, or use some sort of bio-metric authentication (such as a fingerprint scan) in addition to their password to access a system. Weak passwords are a major cause of data breaches and hacks, and MFA is the only true way businesses can prevent that from happening. With MFA, if a hacker uncovers a user’s password, they could not access your systems with just the password, as MFA would prompt them to provide another form of authentication.


Office 365 data, including files stored in SharePoint Online or OneDrive, is not natively backed up, and businesses should employ a third-party backup solution to ensure that Office 365 data can quickly be restored in the event of an incident.

If you want to take Office 365 security seriously, these three steps are a great first start, however, you shouldn’t stop there. For more information on Office 365 security, check out our website or reach out to us for more information.
