Microsoft Defender for Office 365

Microsoft Defender for Office 365 gives you powerful automation to protect your organisation against malicious threats, email compromise, and credential phishing.

You’ve got (suspicious) mail

Complex and/or out-of-date device and environment configuration leave your network wide open to smart new attacks. Add multiple users, devices, and off-site locations into the mix and you’ve extended an open invitation for cybercriminals to enter your environment.

Your challenges:

Inefficiencies

Too many policy options and configurations make staying on top of best practice processes and closing gaps a never-ending challenge.

Wasted resources

Your current email protection solutions are repetitive, costly, and time-consuming – which means you’re wasting valuable security resources.

Poor integration

Complex third-party mail protection solutions take forever to set up, remain imperfect – with admins operating multiple portals.

Complexity

Third-party protection solutions struggle to protect your internal email – while those added mail routing configurations add complication.

Internal threats

You know your users are key to enhancing your security posture, but they don’t have the right level of threat awareness to work securely.

Keeping pace

Attacks don’t stop at email – and malicious actors are now adapting their tactics to focus on less-protected platforms.

Great level of knowledge and all of the team were great to work with. A very positive experience for Stobart Group. Thank you!

FAQ

What’s attack simulation training?

Attack simulation training lets you run realistic attack scenarios to help you identify and find vulnerable users before a real attack impacts your organisation’s bottom line.

You’ll be able to put your security measures to the test with a range of social engineering techniques, including:

  • Credential harvest: An attacker sends a message containing a URL that directs users to a website (often posing as a well-known brand) that’s designed to steal sensitive information.
  • Malware attachment: The attacker sends the recipient a message that contains an attachment that, once opened, runs arbitrary code on the user's device to help the attacker dig even deeper into your network.
  • Link in attachment: A hybrid of a credential harvest, this is where the attacker sends a message that contains a URL inside of an attachment.
  • Link to malware: An attacker sends a message containing a link to an attachment on a well-known file sharing site (such as SharePoint Online or Dropbox) that releases arbitrary code that lets attacker infiltrate your network.
  • Drive-by-URL: An attacker sends a message containing a URL that, once clicked, leads to a website that tries to run background code to either gather information about the recipient or deploy arbitrary code on their device.
