The short version
Managed SOC is the default answer for most mid-market and many enterprise organizations — the economics of a 24/7 in-house SOC rarely work below a certain scale, and managed providers bring detection engineering, threat intelligence, and SOAR tooling that would cost millions to build in-house. In-house wins at the high end, where regulatory, scale, or strategic control make internal ownership the better call. A hybrid posture captures the best of both.
Side-by-side
| Dimension | Managed SOC | In-house SOC | |---|---|---| | 24/7 coverage | Included by default | Requires 8-12+ analysts | | Startup cost | Onboarding 4-6 weeks | 12-18 months to functional | | Ongoing cost | $15K-$100K+/mo based on scope | $1.5M-$5M+/year fully loaded | | Detection engineering | Provider's team + client-specific tuning | Client team (must be hired) | | Threat intelligence | Included (provider's feeds + client) | Subscription cost per feed | | SOAR / automation | Provider's platform | Buy and operate | | Context / domain knowledge | Provider learns over time | Deepest possible | | Strategic control | Shared with provider | Fully internal | | Regulatory attestations | Provider + client | Client |
When managed SOC is the right choice
- The organization is mid-market (typically 100-5000 employees) and cannot economically justify a 24/7 in-house team.
- The talent market is not producing SOC analysts the organization can hire at the comp they offer.
- The organization wants coverage operational in months, not years.
- Regulatory obligations require 24/7 monitoring but not specifically in-house monitoring.
- The internal security team exists and is strong on strategy but thin on ops staffing.
When in-house SOC is the right choice
- The organization is large enough that 8-12 SOC analysts is a rounding error in the security budget.
- Strategic control of detection and response is a core requirement (certain financial services and government contexts).
- The organization's threat profile is unusual or adversary-specific enough that a third party cannot match the tuning.
- Regulatory or contractual terms require internal SOC ownership.
- The organization already has the senior security engineering and detection engineering talent to design and run the SOC.
When hybrid makes sense
Hybrid is the most common posture we see at scale. The pattern:
- Managed SOC handles 24/7 monitoring, tier-1 and tier-2 triage, alert-to-incident handoff.
- Internal team handles security engineering, detection engineering (in partnership with the provider), threat hunting, incident response leadership, vendor oversight, and the board-level security conversation.
- Shared responsibility is documented explicitly — no ambiguous seams between what the provider handles and what internal owns.
Hybrid works when the shared-responsibility boundary is clear and the internal team does not become an "alert triage second team" layered on top of the provider.
The evaluation criteria that matter
For managed SOC selection:
- Detection engineering quality. How do they tune detections to your environment? Ask for examples from similar clients.
- Alert volume and signal-to-noise. What is the expected alert rate, and how much of it will you actually act on?
- Response tooling integration. Do they work in your ticketing/ITSM, or do you work in theirs?
- Escalation paths and SLAs. What happens at 3 a.m. when a critical alert fires?
- Coverage across your stack. Cloud, endpoint, identity, network — which are in scope?
- Regulatory fit. Can they produce the evidence and attestations your audits require?
For in-house SOC planning:
- Realistic hiring plan. Can you actually recruit 8-12 SOC analysts in your geography at your comp?
- Tooling TCO. SIEM, SOAR, EDR, threat intel, UEBA, plus integration and operation cost.
- Senior leadership. Who runs it, who does detection engineering, who leads IR?
- Ramp to functional. 12-18 months is typical; plan for 24.
How Thoughtwave approaches this
Our cybersecurity practice delivers managed SOC services and also supports clients building in-house capability. We run the hybrid model for several clients where we provide 24/7 tier-1/tier-2 with integrated detection engineering, and the client's team owns strategy, hunting, and IR leadership.
