Managed Security Services

24/7 monitoring, detection, and response across your entire environment

Summary

Continuous Security Operations with Centralized Control

21CK provides fully managed security operations designed to deliver continuous visibility, detection, and response across your entire environment. By leveraging XDR technologies and expert-led analysis, security events are monitored, validated, and acted upon in real time.

Our managed services integrate detection, threat hunting, and response into a unified operational model, reducing complexity, minimizing alert fatigue, and ensuring rapid containment of threats across IT and operational systems.

Why Organizations Choose Managed Security

Reduce Operational Risk with Continuous Security Operations

Modern organizations face increasing pressure from ransomware, identity attacks, operational complexity, and growing alert volumes. Managed security services provide continuous monitoring, expert-led response, and centralized visibility to improve security operations without the overhead of building an internal SOC.

Accelerate security maturity with proven operational frameworks
Reduce alert fatigue through centralized monitoring and response
Improve visibility across endpoints, users, networks, and cloud
Strengthen detection and containment of advanced threats
Support both IT and OT environments through unified monitoring
Optimize security operations with expert-led management

Services

Real-Time Threat Detection, Investigation, and Response

Managed Detection

Continuous monitoring and analysis of security events across endpoints, networks, and cloud to identify threats in real time using correlated telemetry and behavioral analytics.

Learn More

Threat Hunting

Proactive investigation of hidden and advanced threats by analyzing attacker behaviors, identifying anomalies, and uncovering malicious activity beyond automated detection.

Learn More

Managed Response

Coordinated incident containment and remediation through automated and analyst-driven actions, including isolation, threat removal, and recovery across affected systems.

Response Capabilities

Endpoint Isolation

Compromised endpoints are immediately isolated to prevent lateral movement and contain threats at the source.

Account Containment

Suspicious or compromised user accounts are restricted to stop unauthorized access and privilege escalation.

Network Containment

Malicious traffic and affected network segments are blocked or segmented to prevent propagation across systems.

Threat Eradication

Malicious processes, files, and persistence mechanisms are removed to restore system integrity and stability.

Incident Investigation

Detailed analysis of attack timelines and behaviors to identify root cause and prevent recurrence.

Coordinated Recovery

Systems are restored and validated to ensure secure operations with strengthened controls post-incident.
