SOC vs SIEM: A Straight Comparison
Buying a SIEM tool is not the same as operating a Security Operations Centre. Here is how the two differ, and what Thai SMBs usually actually need.
A SIEM is software that collects and correlates logs. A SOC is the people, processes, and tooling that operate 24/7: SIEM is often one component inside a managed SOC service.
Comparison at a glance
| SIEM (tool only) | Managed SOC (SOCGuard) | |
|---|---|---|
| What it is | Log platform + rules | Monitoring service + analysts + EDR + reporting |
| Who operates it | Your IT team (if anyone) | SOCGuard Bangkok SOC |
| Typical cost | Licence + infrastructure + staff | From THB 120/endpoint/mo, no setup fee |
| 24/7 coverage | Only if you hire shifts | Included on MDR and above |
| Cloud + endpoint context | Requires integration work | Built into MDR |
| PDPA reporting | You build dashboards | Included on MDR and above |
| Best for | Large teams with SOC staff | Thai SMBs without in-house analysts |
When SIEM alone is enough
Rarely for SMBs. SIEM alone works when you already employ security analysts who tune rules, investigate alerts, and report to management. Without that headcount, a SIEM becomes an expensive log archive.
Common questions
Can I use my existing SIEM with SOCGuard?
We can discuss log forwarding and integration during scoping. Most SMBs start on our bundled stack rather than maintaining a separate SIEM licence.
