Endpoint Security Services

Endpoint security services protect the devices, laptops, desktops, phones, and tablets, that connect to your organization's data and systems. Every endpoint is a potential entry point for attackers, and in a world of remote and hybrid work, the number and variety of endpoints has exploded. Endpoint security combines prevention, detection, and response across all of them, built in the Microsoft ecosystem on Microsoft Defender for Endpoint and Microsoft Intune, under a Zero Trust model.

The endpoint is where most attacks begin, through phishing, malware, or a compromised device, and where data is most exposed. Traditional antivirus is no longer enough; modern endpoint security needs endpoint detection and response (EDR), automated remediation, device compliance enforcement, encryption, and continuous posture monitoring. The challenge is deploying and managing this consistently across every device, including personal and frontline devices, without crippling productivity. That is what endpoint security services deliver: comprehensive, managed protection that detects threats before they spread and keeps every device compliant. ARC deploys Defender for Endpoint and Intune across your organization and operates them as an ongoing security capability.

Endpoint security services on the Microsoft stack cover prevention through response:

• Microsoft Defender for Endpoint. Next-generation antivirus plus EDR, with behavioral detection and threat analytics across devices.
• Microsoft Intune device management. Enrollment, configuration, and policy enforcement across Windows, macOS, iOS, and Android, including BYOD.
• Zero Trust compliance policies. Device health and compliance checks that gate access to corporate resources.
• EDR and automated remediation. Detection of advanced threats with automated investigation and response to contain them quickly.
• Encryption and app control. BitLocker management, application control, and whitelisting to harden devices.
• Posture reporting and analytics. Continuous visibility into device security posture across the fleet.

Common use cases include securing remote and hybrid workforces, protecting BYOD and frontline devices, enforcing Zero Trust access, replacing legacy antivirus with EDR, and achieving compliance through device controls.

ARC delivers endpoint security as a deployed, managed capability:

Assessment. We review your device landscape, current protection, and risks, and define the right Defender and Intune architecture and policies.

Deployment. We roll out Microsoft Defender for Endpoint and Intune across your devices, including Windows, macOS, and mobile, with minimal user disruption.

Policy and Zero Trust. We configure device compliance policies, conditional access integration, encryption, and app control so only healthy, compliant devices reach corporate resources.

EDR and automation. We tune detection and enable automated investigation and remediation so threats are contained fast.

Monitoring and response. We set up posture reporting and, where needed, integrate with Sentinel and Security Copilot for centralized detection and response.

Ongoing management. We operate and optimize endpoint protection over time as devices, users, and threats change.

Strong endpoint security is comprehensive and consistently enforced. ARC applies these principles:

• Cover every device. Protection must extend to all endpoints, including personal and frontline devices, not just corporate laptops.
• Enforce Zero Trust. Gate access on device health and compliance so a compromised device cannot reach sensitive data.
• Move beyond antivirus. Use EDR and automated remediation to catch and contain advanced threats.
• Encrypt and harden. Enforce BitLocker, app control, and secure configuration baselines.
• Centralize visibility. Integrate endpoint signals with your SIEM for unified detection and response.
• Manage continuously. Keep policies, patches, and configurations current as the device fleet evolves.
