Microsoft Cybersecurity is what we do.
Founded by Microsoft technology and cybersecurity veterans who focus exclusively on securing Microsoft cloud environments. All day. Every day.
Stay one step ahead of threats with automated, around-the-clock security checks for Microsoft 365.
Why real time Microsoft 365 Security Configuration Monitoring is important
Today, cyberattacks occur every second and simply configuring security settings isn’t enough. Organizations need to continuously monitor, manage and work on cloud security.
A lack of knowledge and mistakes by admins or MSP’s can inadvertently create major security loopholes in Microsoft 365. In fact, Gartner predicts that by 2026, 99% of cloud security failures will be caused by customer misconfiguration.
Defend 365 closes this gap by providing constant insight into your tenant configuration, catching mistakes, changes or vulnerabilities in real time.
Identify, fix, and monitor security risks in Microsoft 365. Automated. Every day.

Risk Management
Defend 365 not only highlights where your Microsoft 365 security posture is strong or weak, it also gives you the tools to manage risks in a structured way.
When a control fails, you can track the change over time, accept the risk, or link it to a remediation plan. Notes and change references can be logged directly, so your security and IT teams stay aligned.
You get an audit-ready system that shows which risks are known, which are being worked on, and which are fully secured.

MDR vs Defend 365
Why use Defend 365 when you have MDR?
Although MDR is essential once an attack is underway, this should be your Plan B.
MDR and your SOC only detect and contain active threats.
Defend 365 is Plan A.
Defend 365 continuously reduces your risk of incidents by running deep, daily Microsoft 365 security scans. It catches security configuration gaps, misconfigurations, and risky defaults before attackers can exploit them and drastically reducing the likelihood of a data breach.
Defend 365 shows you exactly where the risks are, how to solve it and keeps your tenant hardened 24/7.
Defend 365 means lower risk, fewer incidents, less SOC noise, and more focus on real, unpredictable threats.
