What Is a SOC? — The Security Operations Center Thai Organizations Need to Know
What is a SOC? A 24/7 cybersecurity monitoring center — 6 core functions, in-house SOC vs MDR compared, and how to pick the right fit. Scoped to your needs.
What Is a SOC? — The Security Operations Center Thai Organizations Need to Know
Ever wonder why some large companies detect a breach within minutes, while others take months to even notice? The difference usually comes down to one thing: whether the organization has a SOC.
A SOC (Security Operations Center) is a cybersecurity operations center — a "control tower" staffed by a team of specialists who monitor, detect, analyze, and respond to cyber threats 24 hours a day, 7 days a week.
Put simply, a SOC = people + processes + technology working together to protect an organization from cyberattacks.
What Does a SOC Actually Do? (6 Core Functions)
1. Continuous Monitoring (24/7)
SOC analysts watch dashboards and alerts from the SIEM system around the clock — not just during business hours, but every second of every day, including weekends and the middle of the night.
Why 24/7? Because attackers don't work office hours. A typical in-house security team covers business hours, and every gap outside that window — nights, weekends, public holidays — is time an attacker can operate with nobody watching.
2. Threat Detection
SOC teams use tools such as SIEM, EDR, and IDS/IPS to detect abnormal activity, including:
- Logins from unfamiliar foreign IP addresses
- Unusually large volumes of data access
- Malware communicating with a command-and-control server
- Lateral movement within the network

3. Incident Analysis
When an alert comes in, the SOC team triages it to determine:
- Is it a false positive (an unnecessary alert) or a true positive (a real threat)?
- What severity level is it? (Critical / High / Medium / Low)
- Which systems are affected?
This step matters enormously — a SIEM can generate hundreds of alerts a day, and without someone to analyze them, every alert is meaningless.
4. Incident Response
Once a threat is confirmed, the SOC team takes action:
| Step | Action | Example |
|---|
| Contain | Stop the threat from spreading | Disconnect the infected machine from the network |
| Eradicate | Remove the threat | Delete the malware, close the backdoor |
| Recover | Restore systems | Restore from backup, rotate credentials |
| Lessons Learned | Review after the fact | Tune detection rules to catch it faster next time |

5. Threat Hunting — Proactively Hunting Threats
A good SOC doesn't just wait for alerts to fire — it has a dedicated threat hunting team that actively searches for threats hiding in the environment, using techniques such as:
- Searching for IOCs (Indicators of Compromise) from threat intelligence feeds
- Reviewing logs that triggered no alert but show an abnormal pattern
- Using the MITRE ATT&CK Framework as a guide for the hunt

6. Reporting
A SOC produces several types of reports:
- Daily/Weekly Reports — a summary of events for management
- Incident Reports — details of each individual incident
- Compliance Reports — reports for auditors (ISO 27001, the Computer Crime Act)
🔥 Why Do Thai Organizations Need a SOC?
Threats Don't Wait
Data from ThaiCERT shows that cyber threat incidents in Thailand keep rising year after year — ransomware, phishing, business email compromise (BEC), and data theft are all on the increase.
The Law Requires It
Under the Cybersecurity Act B.E. 2562 (2019), organizations classified as Critical Information Infrastructure (CII) — a list the National Cyber Security Committee most recently updated in September 2025 — must appoint a cybersecurity officer, follow NCSA-issued monitoring standards, and undergo periodic audits (Lexology, Sept 2025) — a SOC is how most CII operators meet that bar.

A Shortage of SOC Analysts
Thailand faces a severe shortage of cybersecurity talent. Building a SOC in-house requires major investment — in people, technology, and process. A better option for most organizations is MDR (Managed Detection & Response), which puts specialists in charge on your behalf.
💡 In-House SOC vs. Outsourced SOC (MDR) — Which Should You Choose?
| Comparison | In-House SOC | MDR / SOC-as-a-Service |
|---|
| Cost | Very high (฿2M+/year) | Scoped to your environment — contact a zcr.ai channel partner for a quote |
| Team required | 3–5 SOC analysts | None (handled by the provider's team) |
| 24/7 monitoring | Requires hiring additional night-shift staff | Depends on the tier: 8×5, 16×5 or 24×7 |
| Technology | Must purchase SIEM, EDR, SOAR yourself | Included in the service |
| Best fit for | Large organizations (1,000+ employees) | SMEs through enterprises, any size |
For most organizations in Thailand → MDR is the more cost-effective choice, because you get a professional-grade SOC without a multi-million-baht investment.
⭐ Renting the SOC instead of building one
Most Thai organizations that need a SOC will never staff one. The alternative is an MDR service — someone else's analysts working your alerts, on your telemetry, around the clock. The zcrMDR service runs on zcrSIEM, the same console described above, and is delivered through an approved zcr.ai channel partner.
What you are actually buying:
- Analysts on a clock, not just a tool — incidents arrive with a severity, and the console tracks mean time to acknowledge, mean time to resolve, and how many stayed inside SLA. Those are the numbers to hold a provider to.
- Coverage you can audit — Detection Rules shows which rules each log source you send actually activates, and where you sit against MITRE ATT&CK tactic by tactic. You can see the blind spots rather than take them on trust.
- Multi-tenant — a tenant switcher in the console, which matters for an MSSP or a group with several subsidiaries.
- SLA-based coverage — 8×5, 16×5, or 24×7 tiers, set in the SLA and statement of work; priced per engagement.
If you already have analysts and only need the platform, the zcrSIEM licence on its own is the cheaper path — MDR is for teams who do not want to hire.
Summary
A SOC is the core of enterprise-grade cyber defense — having the tools isn't enough. You need a team watching and responding around the clock, 24/7.
For Thai organizations that don't yet have a SOC:
- Start with log management → zcrLog, starting at ฿4,000/month
- Add detection and investigation → zcrSIEM, for incidents, hunting, and ATT&CK coverage on the sources it ingests itself — it does not need zcrLog first
- Add people to work it → the MDR service on zcrSIEM, delivered through a channel partner — priced per engagement, ask for a quote
