24/7 SOC to detect and respond to security incidents
In an environment of increasingly virulent cyber threats, marked by expanding attack surfaces and the normalization of remote work, continuous monitoring of the IS becomes essential. The Castelis SOC detects, analyzes, and responds to incidents 24/7 to limit operational, financial, and reputational impact.
A SOC at the heart of your cyber defense
The Castelis SOC is the operational pillar of your cybersecurity. It combines continuous monitoring, human expertise, and permanent improvement of detection to anticipate threats and respond effectively to incidents.
24/7 Monitoring
Continuous monitoring of your IS to quickly detect any suspicious activity and track threat trends through regular security reports.
Advanced Detection
Log correlation and enriched detection rules, combining known scenarios and anomalous behavior detection to identify emerging or targeted threats.
Advanced Analysis
Alert analysis by experienced SOC analysts, supported by machine learning mechanisms to refine detection, reduce false positives, and prioritize incidents.
Incident Response
Immediate assistance in case of an incident by our CSIRT team: isolation, post-incident analysis, and concrete recommendations to limit impact and prevent recurrence.
Cyber Threat Intelligence (CTI)
Continuous monitoring of threats, attack campaigns, and vulnerabilities to anticipate risks specific to your environment.
Threat Hunting
Proactive threat hunting within your IS to identify malicious behaviors undetected by conventional rules.
/ A structured and continuous cyber defense
Our SOC methodology is based on a progressive and proven approach, from log source integration to continuous improvement of detection and response capabilities, without operational disruption.
Onboarding
Integration of log sources, scope framing, and definition of priority detection scenarios.
Collection & Correlation
Log centralization, normalization, and implementation of correlation rules adapted to your IS and risks.
Detection & Analysis
Continuous monitoring, alert qualification, and in-depth analysis by SOC analysts.
Response & Remediation
Incident management, remediation recommendations, and support for resolution.
Continuous Improvement
Rule enrichment, feedback, and adaptation to new threats.
/ Tech stack
The SOC relies on a SIEM at the heart of a detection and response tool ecosystem, integrated into your existing environment to ensure reliability, performance, and scalability.
Stack integrated into your IS, with no dependency on a single proprietary tool.

Frequently asked questions — SOC
Security tools generate alerts, but without continuous human analysis, their effectiveness remains limited. A SOC provides 24/7 supervision, expert alert qualification, reduction of false positives, and a structured response capability in case of an incident.
Yes. Our SOC is dimensioned according to the client’s scope and cyber maturity. It can cover a complex large-group IS or meet the needs of smaller organizations seeking continuous monitoring without a dedicated internal team.
In case of a confirmed incident, SOC analysts qualify the threat, alert the teams involved, and support containment actions. A post-incident analysis is then conducted with concrete recommendations.
