Lenders, Banks & Credit Unions.
Six Threat Categories, One Control Plane
Guardian MxDR covers the full Microsoft 365 attack surface. Every alert feeds into a single monitoring pipeline managed by ABT engineers who understand your environment.
Identity Attacks
Brute force, credential stuffing, token theft, and privilege escalation attempts detected through Entra ID Protection and Conditional Access signals.
Email Threats
Phishing campaigns, business email compromise, malware attachments, and impersonation attempts monitored through Defender for Office 365.
Configuration Drift
Conditional Access policy changes, MFA disablement, sharing permission changes, and DLP policy modifications that weaken your security posture.
Sign-in Anomalies
Impossible travel, risky sign-ins from unknown locations, legacy authentication attempts, and suspicious activity patterns in Entra ID logs.
Data Exfiltration
External sharing spikes, DLP policy violations, large file downloads, and unauthorized data movement tracked through Purview and SharePoint audit logs.
Device Compliance
Intune compliance failures, unmanaged device access attempts, OS patch status, and endpoint health signals that indicate compromised or at-risk devices.
Detect, Investigate, Respond
When MxDR identifies a threat, ABT engineers follow a structured response process. No ticket queues. No waiting for business hours. Real people who know your environment.
Detect
Automated monitoring surfaces anomalies across all six threat categories.
- Defender alert correlation
- Entra ID sign-in analysis
- Configuration change tracking
- Cross-tenant threat intelligence
Investigate
ABT engineers assess severity, trace the attack path, and determine scope.
- Root cause analysis
- Affected account identification
- Lateral movement assessment
- Data exposure evaluation
Respond
Containment, remediation, and hardening to prevent recurrence.
- Account isolation and password reset
- Conditional Access policy tightening
- Configuration restoration
- Post-incident documentation
The EDR Didn't See It. The Antivirus Didn't See It.
Attackers use legitimate Microsoft tools to move laterally, escalate privileges, and wipe environments. MxDR watches the control plane where those attacks happen.
Built on the Stack You Already Own
Guardian MxDR uses the Microsoft Defender suite, Entra ID, Purview, and Intune that your Microsoft 365 licenses already include. No additional agents. No third-party overlays.
- Microsoft Defender for Office 365 monitors email threats, phishing, and business email compromise
- Entra ID Protection detects identity-based attacks, leaked credentials, and risky sign-ins
- Microsoft Purview tracks data movement, DLP violations, and audit trails
- Intune enforces device compliance and reports endpoint health
- Conditional Access policies control who can access what from where
- ABT manages all of it so your team can focus on serving members and clients
