In a world where cyberattacks are increasing exponentially, there’s a group of professionals working tirelessly behind the scenes to protect our digital information. Today we’ll delve into one of the most strategic careers in cybersecurity – the Security Analyst, specifically those specialists working in Security Operations Centers (SOC).
Looking for an entry point into the fascinating world of cybersecurity? This profession is ideal for beginners, doesn’t require overly complex certifications to start, and its demand in the job market is constantly growing, with attractive starting salaries even for junior profiles.
🌍 What is a SOC? Much more than a security department
A Security Operations Center (SOC) functions as the central nervous system of cybersecurity in an organization. It operates 24/7/365, monitoring, detecting, investigating, and responding to threats in real-time. Imagine a control room where security experts observe multiple screens with network activity, alerts, and security indicators – that’s the operational heart of a SOC.
Types of SOCs currently existing
- Internal SOC: Fully managed by the company itself
- SOC as a Service (SOCaaS): Outsourced to specialized providers
- Hybrid SOC: Combines internal and external resources
- Virtual SOC: Operates remotely without a centralized physical location
- Fusion Center: Advanced SOC that integrates multiple security disciplines
According to a Deloitte study, 76% of companies that have suffered significant security breaches lacked a properly established SOC.

Real case: Lisa started as an L1 analyst 8 months ago after completing a cybersecurity bootcamp. “At first, the number of alerts overwhelmed me, but over time I developed a ‘sixth sense’ for identifying suspicious patterns. I remember my first important detection: a targeted phishing attack that had eluded the automatic filters. I detected it because I noticed anomalies in the user’s communication patterns.”
Level 2 – Incident Response: The tactical investigators
Main responsibilities:
- In-depth analysis of complex incidents escalated by Level 1

Approximate salary in Europe: €70,000 – €120,000+ annually (varies by country)
Real experience: “As a threat hunter, I remember a case where I identified an attacker who had remained undetectable for months in a bank’s network. It wasn’t through alerts, but by analyzing anomalous DNS traffic patterns and subtle behaviors that didn’t fit the normal baseline. This detection prevented a potential fraud of millions of dollars.” – Michael, Senior Threat Hunter in Boston.
🛠️ The technological arsenal of the modern SOC
A SOC analyst’s work is supported by a sophisticated ecosystem of tools:
Fundamental systems:
- SIEM (Security Information and Event Management): Platforms like Splunk, IBM QRadar, or ELK Stack that centralize and correlate security events
- EDR/XDR (Endpoint/Extended Detection and Response): Such as CrowdStrike, SentinelOne, or Microsoft Defender for Endpoint
- SOAR (Security Orchestration, Automation and Response): To automate responses to common incidents
- Threat Intelligence Platforms: AlienVault OTX, Recorded Future, or MISP
- Malware analysis systems: Both static and dynamic
- Network monitoring tools: Solutions like Zeek, Suricata, or Darktrace
“The effectiveness of a SOC is not measured by the number of tools it uses, but by how it integrates these tools into a coherent ecosystem adapted to the specific needs of the organization.”
🔐 Key functions that keep organizations secure
The scope of a SOC’s work goes far beyond simply responding to alerts:
Continuous monitoring and detection
- 24/7 surveillance of all the organization’s digital assets
- Early detection of anomalous behaviors through pattern analysis
- Correlation of seemingly unconnected events to identify attack campaigns
- Monitoring of privileged activities to prevent internal abuse
Vulnerability management
- Proactive identification of security flaws before they are exploited
- Prioritization according to real business risk
- Coordination with IT teams to apply critical patches
- Verification that corrections are implemented correctly
Incident response and remediation
- Immediate containment to limit the scope of intrusions
- Forensic analysis to determine the scope and severity of each incident
- Eradication of persistent threats through systematic procedures
- Secure restoration of affected services minimizing downtime
Threat intelligence and hunting
- Collection and analysis of information on relevant attacker tactics
- Proactive search for specific indicators of compromise (IOCs)
- Development of hypotheses about possible undetected attack techniques
- Creation of new detection rules based on emerging threats
📈 The future of the SOC analyst: Emerging trends
The field of Security Operations Centers is rapidly evolving:
Integration of AI and machine learning
ML systems are revolutionizing detection by identifying subtle anomalies that would escape static rules. Future SOC analysts will work closely with AI algorithms to enhance their analytical capabilities.
Cloud SOC and distributed architectures
With the massive migration to cloud environments, SOCs are adapting to protect complex hybrid infrastructures, developing new monitoring and response techniques tailored to these dynamic environments.
Advanced automation and orchestration
Automation is transforming the SOC analyst’s work, allowing them to focus on higher value-added tasks while repetitive processes are managed through automated playbooks and intelligent orchestration.
“Zero Trust” approach and microsegmentation
Modern SOCs are adopting security philosophies based on “never trust, always verify,” which requires new monitoring skills and approaches.

❓ Frequently asked questions about the SOC analyst career
Is it necessary to know how to program to be a SOC analyst?
For initial levels (L1), it’s not essential, although basic scripting knowledge is very useful. For advanced levels (L2/L3), programming becomes an essential skill for automating tasks and performing complex analyses.
How long does it take to progress from level 1 to level 2?
Typically between 1-3 years, depending on exposure to varied incidents, proactivity in learning, and opportunities within the organization.
Do SOC analysts always work in rotating shifts?
L1 teams usually work in shifts to ensure 24/7 coverage. L2 and L3 levels may have more standard schedules with rotating on-call duties for critical incidents.
What’s the difference between a SOC analyst and a pentester?
While the pentester adopts an offensive role simulating attacks to find vulnerabilities, the SOC analyst has a defensive approach, detecting and responding to real threats in systems.
Can a SOC analyst work remotely?
More and more organizations are offering remote positions for SOC analysts, especially after the pandemic, although some highly regulated environments may require physical presence.
