# Enterprise Incident Remediation Workflows | Hexnode UEM & XDR integration In a massive **500,000-device estate**, response velocity is the critical threshold between a localized incident and a catastrophic global outage. This Automation Playbook leverages the native integration between **Hexnode XDR** and **Unified Endpoint Management (UEM)** to deploy autonomous, event-driven **“Agentic” workflows** designed to remediate high-frequency enterprise threats. By leveraging Hexnode’s converged XDR and UEM capabilities, this playbook facilitates a paradigm shift from **reactive ticketing** (manual human response) to **real-time self-healing** (automated system response). This technical framework enables a 500-man technician team to transition from manual task execution to an **architectural oversight model**, ensuring a unified, high-velocity response strategy across the entire global fleet. The Playbook Framework: “Detect-Validate-Remediate” --------------------------------------------------- By unifying the capabilities of detection, validation, and remediation into a single, cohesive engine, Hexnode orchestrates the 500,000-device fleet through a streamlined execution path. It ensures that autonomous remediation occurs instantly without the latency typically caused by fragmented security and management tools. 1. **Detection**: Signals are captured via the **Hexnode XDR API**, identifying anomalies such as unauthorized process execution, brute-force attempts, and known malware signatures. 2. **Validate**: The detected anomalies are cross-referenced with **Open-source threat databases** (OSINT) and native intelligence to filter false positives and assign a **Severity Score** based on asset sensitivity and threat reputation. 3. **Remediate**: High-velocity enforcement is executed via the **Hexnode MQTT Engine**, carrying out **Network Isolation** and **Process Kill** commands based on the severity of criticality score of the device. Critical Hexnode Playbooks --------------------------- 1. ### Ransomware & Host Isolation **Trigger**: Detection of malicious file patterns or high-severity threat signatures via **Hexnode XDR**. **Hexnode XDR Action**: - **Device Isolation**: Severely restrict or cut off the compromised endpoint’s network connectivity, preserving only a secure communication channel with the **Hexnode XDR** console for continued monitoring. - **Process Termination**: Initiation of a **Process Kill** command directly from the XDR console to neutralize malicious processes, targeting both individual PIDs and the entire associated **Process Tree**. **Optional Additional Action from Hexnode UEM:** - **Device Lock**: Automatically move the affected device into a [Dynamic Group](https://www.hexnode.com/mobile-device-management/help/dynamic-device-groups/), which triggers immediate, hardware-level [Lock Device](https://www.hexnode.com/mobile-device-management/help/lock-a-device-using-hexnode-mdm/) remote action. 2. ### Lost/Stolen Device Playbook **Trigger**: Location drift detected outside defined **Geofencing** boundaries or manual **“Lost Mode”** initiation via the Hexnode portal. **Hexnode UEM Action:** - **Activation Lock Management**: Force-enable hardware-level [Activation Lock](https://www.hexnode.com/mobile-device-management/help/how-hexnode-simplifies-apples-activation-lock-feature/) for iOS and macOS devices via Hexnode’s [Advanced Restrictions](https://www.hexnode.com/mobile-device-management/help/set-up-ios-mdm-restrictions-using-hexnode-mdm/) policy, preventing unauthorized device resets or resale. - **Selective Wipe**: Execute a **Selective Wipe** to purge only the **Work Profile** on Android. This secures corporate assets by removing managed apps and data while preserving personal user data. - Access Revocation: Automatically trigger [Conditional Access](https://www.hexnode.com/mobile-device-management/help/set-up-microsoft-entra-conditional-access-integration-in-hexnode/) revocation via **Entra ID**. As the device is flagged “Non-Compliant” in Hexnode UEM, all active SaaS tokens are invalidated, blocking access to corporate cloud resources. 3. ### Instantaneous Threat Patching **Trigger**: High-risk CVEs (CVSS 9.0+) are detected within the **Patches** tab of Hexnode UEM. **Hexnode UEM Action:** - **Automated Patching**: Configure **Auto Patch** automations under the “Patches & Updates” module to proactively download and deploy fixes for critical vulnerabilities, ensuring the global fleet is future-proofed against emerging exploits. - **Real-time Audit**: Continuously monitor the execution and success of these automated deployments via the **Activity Feed** (from the [Automate](https://www.hexnode.com/mobile-device-management/help/automate-device-management-tasks/) tab) for instant verification of the estate’s security posture. Playbook Efficiency Metrics (Automated vs. Manual) --------------------------------------------------- The table below quantifies the transition from **Reactive to Agentic** response times for a 500,000-device estate.

Implementation Checklist: Playbook Phase ----------------------------------------- To transition your 500,000-device estate from manual administration to an **architectural oversight model**, follow this technical checklist to deploy the “Detect-Validate-Remediate” framework. 1. ### Architecture & Integration - **Map XDR Triggers**: Configure the **Hexnode XDR API** to ingest signals like brute-force attempts, unauthorized process execution, and known malware signatures. - **Network Optimization**: Verify that **MQTT Ports 1883/8883** are open across all global segments to ensure the **Triple-Channel Architecture** can deliver sub-second remediation commands. - **Identity Sync**: Establish the handshake between **Hexnode Access** and your IdP **(Entra ID)** to enable automated **Conditional Access** revocation for non-compliant devices. 2. ### Enforcement & Validation - **Configure Device Isolation**: Define the network restrictions required to cut off compromised endpoints from the production environment while maintaining a secure link to the Hexnode console. - **Pilot Simulation**: Execute a controlled end-to-end test of “Lost Mode” and “Ransomware” playbooks on a **Device Group** before global rollout. - **Audit Monitoring**:Review the **Activity Feed** in the **Automate** tab to verify real-time success rates across initial deployment rings. - **Policy Lock**: Finalize **Advanced Restrictions** (such as Activation Lock) to ensure that automated actions cannot be bypassed by local users or attackers during a security event. By operationalizing these **Agentic Playbooks**, your organization moves beyond the limitations of manual intervention into a state of **continuous, autonomous resilience**. In a 500,000-device ecosystem, this framework doesn’t just save time—it eliminates the “window of exposure” that attackers rely on. By shifting your 500-man technician team from reactive troubleshooters to **security architects**, you ensure that every endpoint remains a hardened asset rather than a liability. With Hexnode’s converged XDR and UEM engine, your infrastructure transitions into a self-healing environment, providing a unified, high-velocity defense that scales as fast as the threats it neutralizes.
