A Security Operations Center (SOC) is a 24/7 team of cybersecurity experts responsible for real-time monitoring, detection, and response to security incidents. By combining technologies such as EDR, NDR, and SIEM, SOC delivers full visibility across the IT environment and enables effective response at every stage of an attack. Many organizations choose SOC as a service to achieve faster incident response and stronger security without building an in-house team.

What Is a Security Operations Center?

A Security Operations Center (SOC) is a team of highly skilled IT security analysts responsible for monitoring, detecting, analyzing, and responding to threats in real time, 24 hours a day, 7 days a week. In an era of rapidly evolving cyber threats, SOC plays a critical role in protecting organizations against hacker attacks, data breaches, and unauthorized internal activities.

Due to the challenges and costs associated with building and maintaining an in-house SOC, most companies and institutions choose to outsource this function to an external provider. However, some organizations, most commonly in the banking sector, which is subject to strict regulatory security requirements — do operate their own SOC teams.

Both organizations considering a managed SOC service and those planning to establish an internal SOC should take into account two fundamental operating models.

Line-Based SOC Model

In the traditional approach, the work of security analysts is organized into three lines:

Line 1: The first level is responsible for triaging alerts, distinguishing incidents that require further action from false positives.

Line 2: The second level focuses on more advanced analysis and incident management.

Line 3: The third level handles the most complex analyses, strategic activities, and improvements to the organization’s overall security posture.

This model often proves inefficient for several reasons:

1. The responsibility for the most fundamental decision—whether an alert represents a real threat—rests with the least experienced analysts, increasing the risk of errors.
2. Hierarchical incident handling artificially extends the response process and delays reaction.
3. Dividing SOC work into separate teams can cause communication and coordination issues, as each line specializes in different areas and lacks full situational awareness.

SOC Without Line Separation

An alternative to these challenges is a model in which the entire Security Operations Center operates on a single support line, as implemented by the SOC360 team. This approach assumes that all team members have comparable competencies, enabling them to respond effectively as soon as a threat is detected.

In this model, responsibility for handling an incident end-to-end—from identification through response to client communication—rests with a single analyst, supported by other team members as needed. As a result, every alert receives proper attention in the shortest possible time, and issues related to internal coordination or accountability are eliminated.

Key Areas of SOC Operations – What Do Security Analysts Do?

The scope of daily activities performed by Security Operations Center analysts can be extensive. Their core responsibilities typically include:

• continuous infrastructure monitoring using proactive security systems (EDR, NDR) and SIEM-based analysis;
• rapid and in-depth contextual analysis;
• real-time incident mitigation;
• handling incident reports submitted directly by employees (e.g., via email or phone);
• delivering detailed recommendations to improve security posture.

In addition, a mature and advanced SOC team may also provide:

1. Monitoring Digital Identity and Email Security Systems such as Microsoft 365 and Google Workspace

Monitoring digital identity security systems such as Microsoft 365 and Google Workspace involves continuous tracking and analysis of user activity within these platforms. Modern cloud-based communication and collaboration systems are frequent targets of attacks, particularly phishing and unauthorized access attempts. SOC teams monitor these environments to detect suspicious logins, unauthorized access attempts, account configuration changes, and other indicators of compromise.

2. Digital Forensics and Incident Response (DFIR)

Digital forensics and incident response (DFIR – Digital Forensics and Incident Response) involve analyzing traces of cyberattacks to identify their source, understand attacker techniques, and secure systems against further incidents. SOC teams analyze logs, files, devices, and other data to reconstruct incidents and respond to threats in order to minimize damage and restore systems to full operation.

3. Attack Surface Monitoring (ASM)

Attack Surface Management (ASM) focuses on identifying and monitoring all points that could become targets of cyberattacks. This includes systems, applications, devices, and services connected to the organization’s network that could serve as entry points for attackers. SOC teams analyze these surfaces to identify potential weaknesses and implement protective measures to prevent exploitation.

4. Threat Hunting – Proactive Search for Malicious Activity

Threat hunting is the proactive process of searching for evidence of threats within an organization’s environment. Unlike passive monitoring, it involves actively seeking out unknown threats that may evade traditional security controls. SOC teams leverage both internal and external threat intelligence sources—such as forums, social media, and the dark web—to gather information about emerging threats and search for related indicators within organizational systems.

5. Detection Engineering – Creating Detection Rules Based on Attacker Tactics and Techniques

Detection engineering is the process of creating and optimizing detection rules to identify advanced threats within security systems. SOC teams analyze current threats and attacker tactics and techniques to develop detection logic capable of identifying previously unknown attacks. This enables faster detection of threats attempting to bypass traditional security mechanisms.

6. Vulnerability Scanning and Management

Vulnerability scanning is the process of identifying weaknesses in IT systems that could be exploited by attackers. SOC teams use scanning tools to detect known vulnerabilities and then manage remediation by assessing risk, prioritizing issues, and implementing patches to reduce exploitation risk.

7. Phishing Awareness Campaigns and Management

Phishing awareness campaigns involve simulated phishing attacks designed to increase employee awareness of online fraud. SOC teams run these campaigns to help employees recognize suspicious emails, links, and attachments, thereby reducing the success rate of phishing attacks. SOC also monitors employee responses to evaluate training effectiveness.

8. Security Tool Analysis and Comparison – Supporting Investment Decisions

Security tool analysis involves evaluating available solutions in the context of organizational needs. SOC teams support clients in selecting appropriate monitoring, detection, and protection technologies, assisting in procurement and implementation decisions that best address data and system security requirements.

9. Cyber Threat Intelligence (CTI)

Cyber Threat Intelligence (CTI) is the process of collecting and analyzing information about emerging cyber threats. SOC teams deliver up-to-date insights into attack techniques, threat types, and cybercrime trends, enabling organizations to adapt their security mechanisms to a changing threat landscape.

10. Security Assessments

Security assessments evaluate an organization’s current security posture. SOC teams analyze whether systems and procedures align with best practices and provide recommendations to improve security in areas such as access control, data management, and threat protection.

11. Training for Internal SOC Teams

Technologies Used by SOC

Core technologies used by SOC teams include EDR (Endpoint Detection and Response), NDR (Network Detection and Response), and SIEM (Security Information and Event Management), collectively known as the SOC Visibility Triad.

EDR systems focus on monitoring and protecting endpoints such as workstations, servers, and mobile devices, forming the foundation of IT security by addressing up to 70% of attack techniques described in the MITRE ATT&CK matrix.

NDR solutions protect network traffic and effectively identify misconfigurations, policy violations, performance degradation, and new attack techniques, complementing EDR to maximize coverage.

SIEM systems collect and process all IT security events using logs and data from various sources, including those not natively covered by EDR or NDR (e.g., firewall logs, web servers, Active Directory). While SIEM relies on predefined correlation rules and may struggle with advanced attacks, it significantly supports post-incident analysis.

Some SOC providers also use SOAR (Security Orchestration, Automation, and Response) to integrate security tools and automate incident response.

Cloud security technologies such as CNAPP (Cloud-Native Application Protection Platform) also play a key role in securing hybrid and multicloud environments.

Why Do You Need SOC Services?

Thanks to advanced technologies and expertise, SOC analysts can mitigate attacks at multiple stages of the cyber kill chain—from phishing and data-stealing malware (stealers) to advanced ransomware attacks.
