How We Secure Your Microsoft 365 Environment with MXDR

Our team adheres to a clear process that merges expert cybersecurity knowledge with Microsoft XDR services to shield your Microsoft 365 environment.

Step 1. Initial Assessment and Onboarding

We start off by reviewing your current Microsoft 365 configuration, user accounts and security policies. We investigate endpoints, email gateways and identity management for configuration weaknesses. All this allows our professionals to optimize managed extended detection for your particular needs.

Step 2. Environment and Policy Configuration

Once onboarding is complete, we integrate Microsoft Defender and any relevant third-party tools under a single oversight model. Further, we will implement response automation rules in your tenant, fine-tune access controls in Azure Active Directory, and activate threat hunting over SharePoint, Teams, etc.

Step 3. Threat Detection and Monitoring

At this point, our detection and response service goes into monitoring Microsoft 365 XDR signals. Automated analytics filter security alerts and our security experts look for deeper patterns that indicate threats coming through email, file sharing, and collaboration channels.

Step 4. Incident Response and Remediation

Our response MXDR team will investigate the root cause whenever a threat is detected and execute quarantining of affected endpoints or mailboxes. We then notify the client and immediately initiate remediation steps to contain any lateral movement. If required, we will collaborate with your in-house security team to rapidly deploy advanced response capabilities.

Step 5. Continual Improvement and Reporting

Our work doesn't end with remediation; we further continue to refine the threat detection rules, update threat intelligence, and improve response service workflows for greater efficiency. Our regular reporting will highlight key findings, trends and potential threats needing your attention.

questions & answers

Frequently asked questions

What's the difference between MDR and MXDR?

While MDR has to do with primarily threat monitoring and response within specific environments, MXDR does so much more: it unifies data across endpoints, email, cloud applications, and user accounts, augmenting tech-driven automation with human oversight. MXDR for Microsoft 365 stitches together several security signals to give deeper visibility into your whole Microsoft ecosystem for quicker response times.

Why do I need an MXDR solution for my Microsoft 365 environment?

Microsoft 365 is one of the most business-critical platforms for email, file sharing, and collaboration. Without advanced threat detection and automated response capabilities, your organization may overlook the suspicious activity buried within an email or a repository of files. Using our MXDR for Microsoft, extended detection and proactive remediation are always available, thereby reducing the risk of a cyber incident.

Does MXDR replace in-house security teams?

No, MXDR extends in-house capabilities and supports continuously, but it doesn't remove the need for internal expertise. Rather, MXDR services extend your internal staff by managing repetitive threat monitoring, providing advanced analytics, and supporting rapid incident response to free more time for your team to devote to strategic work, such as reviewing policies and undertaking compliance initiatives.

Will MXDR disrupt existing security systems or workflows?

Our Microsoft managed extended detection and response will work seamlessly with your existing solutions. We work with security teams to consolidate logging, reporting and alerting into a single dashboard for incident tracking. Over time, the combined data we gather help in prioritizing investigations and improving operational efficiency.

What businesses benefit most from MXDR services?

MXDR services can be useful for any business using Microsoft 365. Highly regulated industries like Healthcare, Finance and Legal find it more valuable because of compliance requirements. Small to medium-sized businesses also get enterprise protection without having to invest in an expensive in-house security team.
