What is Microsoft Defender
Microsoft Defender is Microsoft’s portfolio of security technologies designed to protect organisations against modern cyber threats.
Microsoft Defender provides capabilities across multiple areas of your environment, including endpoint protection, email and collaboration security, identity protection, cloud applications and threat detection and response.
Together, these capabilities help organisations move beyond individual security controls towards a more connected approach to preventing, detecting, investigating and responding to threats.
What we help with
Defending your organisation requires more than deploying security software. We help you understand where your greatest threat exposure lies, strengthen preventative controls and improve your ability to detect and respond when something gets through.
Protect your endpoints
Endpoints remain a common target for attackers and can provide a route into your wider environment.
We help organisations implement Microsoft Defender for Endpoint to strengthen protection across Windows and supported devices, improve visibility of endpoint activity and respond to threats more effectively.
Protect email and collaboration
Email remains one of the most common routes for phishing, malware and other attacks.
We help you use Microsoft Defender for Office 365 to improve protection against malicious messages, phishing, unsafe links and attachments, while strengthening security across Microsoft 365 collaboration services.
Detect identity-based threats
Compromised identities can provide attackers with a path into your environment, particularly where traditional Active Directory remains in use.
We help organisations use Microsoft Defender for Identity to identify suspicious activity and attacks targeting identities, providing additional visibility alongside Microsoft Entra’s identity and access controls.
Understand your attack surface
You can’t protect what you can’t see.
We help you improve visibility of vulnerabilities, exposed assets and potential attack paths so that your security team can prioritise the weaknesses most likely to create risk.
Detect and respond to threats
Effective security requires more than prevention. When suspicious activity occurs, your team needs the visibility and processes needed to investigate and respond.
We help organisations use Microsoft Defender XDR to bring signals together across endpoints, identities, email and other Microsoft security services, improving investigation and response.
Secure cloud applications
Cloud applications can introduce new risks around access, data and user activity.
We help organisations use Microsoft Defender for Cloud Apps to discover applications, understand how they’re being used and apply appropriate security controls.
Strengthen security operations
Security teams can quickly become overwhelmed by alerts from multiple tools.
We help organisations improve the way Defender signals are monitored, investigated and acted upon, helping reduce unnecessary noise and establish more effective security operations.

Featured Microsoft Defender Case Study
When a UK financial institution needed to replace fragmented, legacy security tools, they partnered with Intelogy to transition to a modern, cloud-first defence model.
