SENTRY — SOC vs. NOC

SOC vs. NOC: Different Centers, Different Jobs

Both watch systems around the clock. Both use dashboards and alerts. But a Security Operations Center and a Network Operations Center exist to answer completely different questions — and confusing the two leaves real gaps.

Why Organizations Often Need Both

A NOC protects against natural disruptions — hardware failure, capacity issues, misconfiguration. A SOC protects against deliberate ones — an attacker actively working against you. An outage and an active breach can look similar in the first few minutes (a system going dark), which is exactly why the two functions need to be coordinated, even when they’re staffed and tooled separately.

Some organizations merge the two into a combined “SNOC,” while others keep them fully separate with a defined handoff process. Either way, the important thing is that both functions exist and talk to each other — a security incident with network-visible symptoms shouldn’t sit in a NOC queue waiting to be triaged as a security event, and vice versa.

Frequently Asked Questions

Does Armorstack operate both a SOC and a NOC?
Armorstack SENTRY’s SOC handles security monitoring, detection, and response. For network uptime and infrastructure monitoring, that work is coordinated through Armorstack’s broader managed IT and CORE portfolio rather than treated as a security function.
Can one team run both a SOC and a NOC?
It happens, particularly in smaller organizations, but the skill sets are genuinely different — network administration versus threat analysis — so quality on one side often suffers without dedicated depth on both.
If we already have a NOC, do we still need a SOC?
Yes. A NOC monitoring for outages will not reliably catch a credential compromise, lateral movement, or data exfiltration — those require the security-specific detection and response a SOC (or SOC-as-a-Service) is built for.
