What Is Microsoft Defender for Office 365 (SaaS)?

FAQ’s, tips and insights > Cyber Security

In today’s threat landscape, protecting your business email, documents, and collaboration tools is critical. Microsoft Defender for Office 365 is a cloud-based cybersecurity solution designed specifically for Microsoft 365 environments—and it’s something every forward-thinking business should understand.

No matter the business in Perth, here’s how this SaaS security tool can make a big difference—with support from a trusted IT company like Epic IT.

What is Microsoft Defender for Office 365?

Microsoft Defender for Office 365 is a cloud-native security solution that helps protect your Microsoft 365 apps—like Outlook, SharePoint, OneDrive, and Teams—from phishing, malware, ransomware, and business email compromise. It’s built to stop threats before they reach your inbox or network.

Is it a SaaS solution?

Yes—Defender for Office 365 is a Software as a Service (SaaS) product, fully managed and hosted by Microsoft. That means no local installations, no server maintenance, and automatic updates with the latest threat intelligence.

What kind of threats does it block?

This SaaS-based solution protects your users from:

  • Malicious attachments
  • Suspicious links (in real time)
  • Phishing and spoofing attempts
  • Business email compromise (BEC)
  • Zero-day malware

It uses AI, machine learning, and Microsoft’s global threat network to catch even the most advanced attacks.

Begin your cybersecurity journey here.

Do I still need antivirus software?

Yes. Defender for Office 365 secures your Microsoft 365 apps, but it doesn’t replace traditional endpoint protection. For full coverage, your business should also have antivirus and endpoint protection in place—something your MSP or IT support provider can manage for you.

How does a local IT company help?

Working with an IT support provider like Epic IT means you don’t just have access to Defender—you get it configured and monitored properly. We:

  • Apply security best practices
  • Respond to alerts in real time
  • Train your team to avoid risky behaviour
  • Integrate Defender into your broader cybersecurity stack

Is it included with Microsoft 365?

That depends on your license. Defender for Office 365 is included with Microsoft 365 Business Premium and E5, but it’s an add-on for most other plans. We can help you choose the right licensing model to get the most value for your investment.

How do I get started?

You don’t need to go it alone. Epic IT can help you deploy Microsoft Defender for Office 365 as part of a complete cybersecurity strategy for your organisation. Whether you need a one-time setup or fully managed protection, we’ve got you covered.
