Unify Enterprise Visibility with Cross-Domain XDR & Threat Intelligence
Stop advanced persistent threats natively. SourceMash delivers specialized engineering, zero-trust architecture hardening, and automated orchestration across the Microsoft Defender suite onverting disparate signals into a unified security ecosystem.
Our Microsoft Security Practices
Three Specializations. One Consolidated Defending Layer.
Break down corporate telemetry silos. SourceMash coordinates native Microsoft 365 security suites to establish automated incident timelines and precise threat hunting parameters across endpoints, infrastructure, and user identities.
Practice 01
Endpoint Detection & Advanced Identity Hardening
Endpoints and enterprise identity frameworks remain primary entry pathways for modern cyber adversaries. SourceMash integrates Microsoft Defender for Endpoint (MDE) and Defender for Identity (MDI) into a single analytical layer. By configuring behavioral heuristics, attack surface reduction rules, and continuous Active Directory log inspection, we identify credential harvesting loops, anomalous service creation, and unauthorized privilege escalations instantly.
Microsoft Defender for Endpoint (MDE)
Deploying next-gen behavioral endpoint controls natively. We leverage built-in Windows kernel sensors alongside specialized macOS and Linux agents to apply strict Exploit Protection and Tamper Proofing layers across your device arrays.
Microsoft Defender for Identity (MDI)
Securing legacy Active Directory and Hybrid infrastructure networks. We engineer distributed security sensors onto domain controllers to capture suspicious protocol manipulations like Pass-the-Ticket, Golden Ticket, and remote thread injections.
Conditional Access & Entra ID Integration
Linking endpoint risk scores into explicit authentication boundaries. SourceMash configures Entra ID access controls so that machines displaying an active infection drop to a high-risk state, triggering instant token invalidation and enforcing localized step-up MFA criteria.
Endpoint & Identity Core Capabilities
Advanced KQL Hunting
Our security analysts engineer custom Kusto Query Language (KQL) scripts to run automated proactive trace reviews across raw system processes.
Incident Storyboarding
XDR automatically correlates telemetry events from endpoint memory and credential changes into a single chronological incident graph.
Host Isolation Actions
Instant remote logical isolation blocks compromised enterprise devices from performing lateral file system access over the network.
Vulnerability Management
Defender TVM provides software inventories, misconfiguration trends, and prioritized update paths without scanning overhead.
Practice 02
Cloud App Security (CASB) & Collaboration Guardrails
Sprawling SaaS use and persistent phishing campaigns bypass outdated network defenses. SourceMash deploys Microsoft Defender for Cloud Apps (MDCA) alongside Defender for Office 365 (MDO) to construct an intelligent data shield. We audit and control shadow IT infrastructure, evaluate unsafe email links at the operational gateway, and execute deep visibility controls across your digital communication channels.
Defender for Cloud Apps (MDCA)
Deploying enterprise CASB governance. We integrate firewalls and endpoint telemetry arrays to continuously map cloud apps in use, evaluate threat profiles, and block unsanctioned file sharing pipelines instantly.
Defender for Office 365 (MDO)
Securing email ecosystems and collaboration platforms. We engineer explicit anti-phishing parameters, activate dynamic safe attachment sandboxing, and expand tracking across Microsoft Teams and SharePoint hubs.
Microsoft Purview Data Loss Prevention
Protecting high-value intellectual property. We design semantic labeling logic that runs inside the endpoint lifecycle to automatically discover, catalog, and block the unauthorized transmission of sensitive enterprise data assets.
Cloud Apps & Data Security Core Capabilities
Anomalous Activity Alarms
Continuous parsing flags high-volume document downloads or mass file deletion runs performed on external networks.
Impossible Travel Analysis
Identity tracking analytics flag sessions when login attempts occur across conflicting geographic areas within a physical travel window.
OAuth Permission Checks
Continuous validation monitors third-party cloud integrations, revoking app authorizations that request risky mailbox access rights.
Copilot for Security Prep
We structure your backend security definitions to prepare your threat defense operations for AI-driven natural language queries.
Practice 03
Unified SecOps Platform & Self-Healing Playbooks
Alert verification pipelines must outpace modern exploit methods. SourceMash unifies the Microsoft Defender XDR interface with cloud native SIEM architectures. By building Automated Investigation and Remediation (AIR) workflows, we configure self-healing parameters that automatically evaluate, contain, and fix complex alerts across your cloud arrays without manual intervention.
Automated Investigation & Remediation (AIR)
Configuring native self-healing engines. We define explicit playbook parameters that inspect memory processes, clean registry configurations, and neutralize malicious scripts automatically across devices.
Microsoft Sentinel SIEM Sync
Unifying cross-domain telemetry fields. We construct low-latency log pipelines via the unified Security Operations platform, mapping alerts into Sentinel workspaces for efficient correlation and long-term compliance storage.
Custom Logic App Playbooks
Extending orchestration capabilities outside the Microsoft ecosystem. We develop specialized Azure Logic Apps that trigger instantly upon XDR detections to update external firewalls, isolate accounts, and document incident details in ServiceNow.
Unlocking the Full Power of E5: Native Integration Over Disparate Agents.
Organizations frequently load endpoints with over half a dozen separate agent packages for antivirus, patch verification, configuration tracking, and tracking logs degrading system execution speed and creating visibility gaps. The Microsoft Defender ecosystem runs natively inside the core OS framework, eliminating agent resource competition. SourceMash configures and activates these built-in system parameters, maximizing your E5 licensing ROI and hardening defense structures without the friction of secondary agent software rollouts.
