In our other blog posts, we have focused on what a SOC (Security Operations Center) is and what you should look for when choosing a SOC MDR (Managed Detection and Response) provider. In this article, we focus on how Sicra SOC MDR detects and responds to cyber threats.

Continuous monitoring in an AI-driven threat landscape

Cybercriminals have adopted artificial intelligence (AI) to automate and scale their attacks. This has led to an explosion in the number of complex attack attempts, ranging from highly convincing phishing emails to sophisticated network intrusions.

Continuous Threat Monitoring means that security data from across the organization’s IT environment is collected and analyzed in real time, around the clock without interruption. The goal is to detect anomalies and attacks as early as possible so their impact can be limited.

Sicra SOC MDR by Arctic Wolf does this by combining three data sources that together provide a comprehensive view of the threat landscape:

• Network monitoring: Traffic and behavior across all network segments.
• Endpoint monitoring: Activity on servers, PCs, and mobile devices.
• Cloud monitoring: Events across cloud platforms such as Microsoft 365, Azure, AWS, and GCP.

How Sicra SOC works, step by step

1. Large-scale data collection

Arctic Wolf’s global platform collects data from more than 7 million endpoint agents and sensors worldwide. Every day, Arctic Wolf analyzes more than 1 trillion security events. This data provides a unique ability to identify patterns and threats that may rarely, if ever, have been seen within a single customer environment.

2. Analysis and correlation

Raw log data is useless without context. Sicra SOC uses Arctic Wolf’s machine learning models to correlate events across systems and identify behavior that may indicate an attack, even when each individual signal appears harmless in isolation. This dramatically reduces false positives and ensures that the security team can focus on genuine threats.

3. Human analysis

Technology alone is not enough. Arctic Wolf’s security experts review all alerts that the platform flags as critical. Sicra’s local team can also become directly involved when needed, particularly in situations that require knowledge of Norwegian regulatory requirements or local context.

4. Rapid alerting and response

When a threat is confirmed, your organization is notified immediately. Incident response begins in parallel, including analysis, isolation of affected systems, remediation, and reporting. You get a complete overview without having to coordinate everything yourself.

5. Learning and improvement

After each incident, alert thresholds and signatures are adjusted through a process Sicra calls alert tuning. Over time, the service becomes increasingly precise and better adapted to your organization’s specific threat profile.

Why rapid detection matters

Attackers move quickly. Once inside a network, their goal is to move laterally, escalate privileges, and exfiltrate data before anyone detects them. The average dwell time for an attacker in a network is more than 200 days globally. With Sicra SOC, this can be reduced to minutes or hours.

Nights and weekends are particularly important: 45 percent of security alerts are triggered outside normal working hours, and 25 percent occur on weekends. An organization without 24/7 monitoring is, in practice, unprotected much of the time.

Threat hunting: Looking for what does not trigger an alert

Some threats are designed to evade automated detection. Sicra SOC provides proactive threat hunting, a manual investigation in which the security team actively searches for indicators of compromise that have not triggered alerts. This is particularly valuable after new vulnerabilities have been disclosed or when an organization suspects that it may have been compromised.

Incident response: From alert to normal operations

Sicra SOC Incident Response (IR) steps in during serious incidents that require more than standard MDR response:

• On-site incident response: Sicra’s team can come on site to assess the scope of the incident.
• Data collection and investigation: Collection of forensic data from critical systems.
• Recovery: Secure restoration of the IT environment to normal production.
• Coordination with authorities: Sicra handles communication with the Norwegian Data Protection Authority, Kripos, NSM, and the police when needed.

In summary: How Sicra SOC detects threats faster

• Arctic Wolf’s platform collects data from more than 7 million agents and analyzes 1 trillion events every day. This provides an unmatched data foundation for distinguishing false alerts from genuine threats.
• Correlation across networks, endpoints, and cloud environments
• Human expertise to assess and confirm threats
• Immediate alerting and incident response
• Proactive threat hunting for threats that do not trigger automated alerts
• Local Norwegian response and coordination with authorities during serious incidents
