MDR Services for Microsoft 365 Defender

Detect and Disrupt Attacks Beyond the Endpoint

CRITICALSTART® MDR for Microsoft 365 Defender extends your security defenses across your domain – from endpoint, to email, to user credentials, to cloud apps, to…(ok, you get the idea).

We go beyond response recommendations, and can take action on your behalf

If you want us to recommend response actions, we can do that. But when minutes count, our Microsoft security experts can actually become an extension of your team and provide remediation and response actions to the threat as soon as it’s detected.

In short, we integrate with Microsoft 365 Defender to detect, investigate and respond to all alerts with the right actions across identity, email and cloud…(and we mean all alerts).

Here’s a quick view of what you get:

IOC management on us

Microsoft is the fastest-moving security company today. IOCs are published and updated hourly across different locations. Leveraging the Critical Start Threat Navigator, we manage and maintain, out-of-box detections and IOCs. Detection content is also mapped to the industry leading MITRE ATT&CK® Framework.

Protection against user account attacks

Our MDR services not only detect but can also take response actions for you to disrupt user account attacks. And an integration with Microsoft Outlook “Report Message” allows us to further support you with investigation and response actions for your employee submitted emails that are suspected phishing attacks.


    Stopping credential email phishing attacks

    Successful attacks expose your organization to data breaches through standard user account access methods. Our MDR services will detect and disrupt suspicious email threats 24x7x365 through detection, investigation, and remediation of platform and user-reported phishing attacks.


    Disrupting brute force and stolen credential attacks

    Preying on weak user passwords is still a highly effective way to gain access to your organization. Protect the identities of your users, prevent takeovers of their credentials, and stop brute force attacks with MDR services for Microsoft 365 Defender.


    Stopping attacks on data in cloud apps

    Adversaries know that by using legitimate credentials, they have insider access to your organization and that makes it harder for you to detect them. Prevent takeovers of user credentials, obstruct lateral movement to other apps, and disrupt attacks against Cloud apps.
