Endpoints are attackers’ most valuable target, making strong endpoint security critical for every organization. Picture this: an employee receives a message that looks routine—“Your corporate SSO session expired—tap to re-verify.” Busy and distracted, they click through quickly.

Within minutes, an attacker has valid access. They move deeper into cloud apps, harvest credentials, and disable defenses. Hours later, sensitive data starts leaking. By the time the SOC (Security Operations Center) detects suspicious activity, the attacker has already staged extortion. This is today’s kill chain—and it thrives at the endpoint.

Why endpoints are the prime target

Attackers go where people, credentials, and access meet—the endpoint. Social engineering remains one of the most effective entry points. Phishing converts human attention into compromise in seconds. Studies show the median time for a user to fall for a phishing email is under a minute.

Stolen or misused credentials are among the top actions in breaches. That’s why endpoint security is no longer optional—it’s essential.

Meanwhile, ransomware crews don’t just bypass defenses—they try to disable them. Playbooks now include “EDR killers” and driver exploits designed to blind endpoint detection before encryption or data theft. This makes tamper-resistant agents and managed detection critical.

Compliance makes endpoint security mandatory

If your organization handles payments, healthcare data or federal information, endpoint controls are not just best practice—they are required.

• PCI DSS v4.0.1 raises the bar for MFA and malware controls. It demands consistent authentication and monitoring at endpoints, not just at the network edge.
• HIPAA Security Rule focuses on encryption, access control, and risk analysis for devices handling ePHI. Endpoints are central to these safeguards.
• NIST Zero Trust guidance treats endpoints as policy enforcement points. Continuous verification is key to reducing risk.
  In short, compliance frameworks assume strong endpoint security is in place.

From problem to solution: How OpenText™ MxDR helps

Attackers love endpoints because they offer quick access to data and credentials. Defenders need visibility, control, and rapid response. OpenText Managed Extended Detection and Response (MxDR) delivers exactly that. MxDR combines 24/7 threat hunting with analytics across endpoints, identities, and cloud. Its MxDR Advanced EDR Agent, powered by SentinelOne Complete, provides hardened telemetry and autonomous containment for Windows and macOS devices.

Break the pre-ransom chain

Human operated attacks follow predictable steps: initial access, credential theft, lateral movement, persistence, and finally encryption or extortion. Industry guidance stresses early detection and isolation—before ransomware executes.
MxDR enables automated device isolation, process termination, and rapid remediation under managed oversight.

Result: Speed. Isolation and kill-switch actions cut detection-to-disruption time from hours to minutes.

Stand up to EDR tampering

Attackers increasingly use driver exploits to kill endpoint defenses. The MxDR Advanced EDR Agent—powered by SentinelOne Complete—includes kernel-level tamper protection, behavioral AI, and rollback capabilities. These features help withstand attempts to disable security tools.

Result: Resilience. Hardened agents and managed oversight frustrate attackers and increase detection chances.

Operational depth with managed security services

Technology alone isn’t enough. OpenText Managed Security Services add vulnerability management, compliance support, and incident response readiness. This ensures PCI DSS and HIPAA requirements are met and Zero Trust principles are applied consistently.

Result: Compliance confidence. Logging, MFA (multi-factor authentication), and encryption align with regulatory expectations.

The bottom line

Endpoints remain the prime target for attackers because that’s where users, credentials, and workflows converge. Treating them as passive assets leaves the door open. Turning them into active defenders—with resilient agents and managed detection—shuts that door before attackers can move laterally or exfiltrate data.

That’s why OpenText MxDR, featuring the MxDR Advanced EDR Agent powered by SentinelOne Complete, was built for this reality: detect early, contain fast, and withstand tampering so attacks stop before ransom or breach.

Ready to strengthen your defenses? Let’s map your endpoint attack surface, assess exposure, and build a managed response plan aligned with PCI DSS v4.0.1, HIPAA safeguards, and NIST Zero Trust principles—so the next 'routine' click doesn’t become tomorrow’s breach.

Cybersecurity isn’t a one-time effort—it’s an ongoing strategy that demands visibility, expertise, and proactive defense. If you’re ready to take your security posture to the next level, explore how Managed Extended Detection and Response (MxDR) can transform your resilience.
