MDR vs In-House SOC: How Federal Buyers Should Make the Build-vs-Buy Decision

Building a U.S.-citizen 24/7 SOC takes twelve to twenty cleared analysts, eighteen to thirty-six months, and seven figures of recurring cost. MDR delivers the same outcomes on day one. This guide compares both paths on cost, staffing, time-to-coverage, and risk so federal buyers can decide which one fits.
The build-vs-buy decision is more than a budget question

Build the Capability, or Buy the Outcome

Building an in-house SOC means hiring and retaining cleared U.S.-citizen analysts across three shifts, licensing SIEM and EDR platforms, building detection content, writing playbooks, and operating the service indefinitely. The capital cost lands first; the operating cost compounds for years. The capability stays with you.
Buying MDR means contracting a FedRAMP-authorized provider to operate the SOC, applying their existing analyst bench and detection engineering to your environment. The cost lands as a monthly or annual line item starting day one. There is no eighteen-month ramp. The capability stays with the provider; you receive outcomes.
What it actually takes to build a federal SOC

The In-House Build Path

Building a 24/7 U.S.-citizen SOC is a multi-year program. Five operational realities determine whether the build will succeed.
1
Twelve to twenty cleared analysts
Sustaining 24/7 coverage requires three shifts of two to three analysts each, plus supervisors, plus weekend and holiday coverage. The standard staffing model is twelve to twenty analysts to maintain primary plus secondary coverage. U.S.-citizen analysts with clearance or clearance eligibility cost between one hundred fifty thousand and two hundred fifty thousand per FTE all-in.
2
Eighteen to thirty-six months to operational capability
Hiring cleared U.S.-citizen analysts in the current market typically takes six to nine months per FTE. Building detection content, tuning playbooks, and reaching incident response maturity takes another twelve to eighteen months after initial staffing. A SOC that starts day-one detection at ninety percent maturity is rare.
3
Three to five million dollar annual operating budget
Total run-rate including salaries, SIEM and EDR licenses, threat intelligence subscriptions, detection engineering tooling, facility costs, and contractor surge support typically lands between three and five million dollars annually for a federal-grade SOC at minimum viable scale. The number scales with environment size.
4
Continuous detection engineering and tuning
An effective SOC requires ongoing detection content development, false positive reduction, and threat-hunt program maintenance. This is a specialized role, not a Tier 1 task. The detection engineering function is often the gap between a SOC that produces noise and one that produces actionable alerts.
5
Recovery posture for analyst turnover
Cleared cyber analyst turnover runs fifteen to thirty percent annually in the federal market. Each departure represents months of lost productivity during refill. A SOC plan without explicit retention strategy and surge contracting tends to degrade rather than mature.

The MDR Buy Path

MDR providers operate the SOC you would otherwise build. The contract starts producing outcomes within days, not months. Day-one staffing: the provider has the cleared U.S.-citizen analyst bench already hired and producing. There is no eighteen-month ramp. Coverage starts at the contract start date. Mature detection content: the provider operates established detection rules, threat-hunt programs, and incident response playbooks. The same content stack covers all the provider's customers, which means it sees more attack patterns than any single in-house SOC ever could. Inheritable security controls: a FedRAMP-authorized MDR provider passes inheritable controls into the customer authorization boundary. The customer's NIST SP 800-53 assessment scope shrinks. This is structurally impossible with an in-house SOC. Predictable cost: MDR contracts are typically firm fixed price per endpoint, per user, or as a fixed retainer with overage. The cost is forecastable, the staff retention risk is the provider's problem, and the budget conversation with leadership is about a line item, not a department. The trade is control. The customer does not own the detection engineering, does not direct the analyst priorities, and depends on the provider's roadmap. For some missions this is unacceptable; for most federal and DIB missions it is the better trade.
MDR vs in-house SOC capability comparison
Six dimensions where build and buy diverge

Side-by-Side: Build vs Buy

On a spreadsheet, build and buy look like two cost lines. The operational reality differs across six dimensions.
1
Time to coverage
Build: eighteen to thirty-six months from staffing start to operational maturity. Buy: days to weeks from contract start. The lag matters for environments that have a compliance or threat-driven deadline.
2
Total cost (Year 1)
Build: typically four to six million in Year 1 (capital plus salary ramp plus tool licenses). Buy: typically five hundred thousand to two million in Year 1 depending on environment size. Year 1 favors buy. Years five and beyond depend on environment scale.
3
Analyst retention risk
Build: customer carries one hundred percent of turnover risk. A mid-tier analyst leaving means six to twelve months of degraded coverage during backfill. Buy: provider carries turnover risk and rotates analyst bench to keep coverage continuous.
4
Detection content depth
Build: detection content matures over years and is sized for one customer's environment. Buy: provider operates content across many customers, so attack patterns observed elsewhere often produce detections in your environment without your team building them.
5
Inheritable controls
Build: in-house SOC does not produce inheritable controls. Customer carries the full NIST SP 800-53 control responsibility. Buy: FedRAMP-authorized MDR provider passes inheritable controls. The customer authorization boundary shrinks.
6
Capability ownership
Build: the customer owns the SOC, the people, the playbooks, the institutional knowledge. Buy: the provider owns those. For missions where SOC capability is a strategic asset (intelligence community, certain DoD missions), build may be the right answer regardless of cost.
Federal procurement criteria reshape the decision

Federal Build-vs-Buy Considerations

Federal, DoD, and DIB buyers face procurement and authorization criteria that compound the operational economics.
FedRAMP inheritance is only available on the buy path A FedRAMP-authorized MDR provider passes inheritable controls into the customer authorization boundary. Building an in-house SOC does not produce FedRAMP-inheritable controls. For customers where the FedRAMP assessment scope drives multi-million-dollar costs, the inheritance value alone often exceeds the MDR contract value.
Cleared analyst hiring is constrained The supply of cleared or clearance-eligible U.S.-citizen cyber analysts is smaller than open job postings in any given quarter. Federal-capable MDR providers compete in the same labor market. The difference is they have the recruiting pipeline, the clearance sponsorship process, and the retention structure already running. Building a new pipeline from scratch is slower than buying access to an existing one.
DoD Impact Level coverage requires authorization investment If the customer environment is DoD IL-4 or IL-5, the in-house SOC must operate in an IL-authorized environment, which adds infrastructure and operational cost. Buying MDR from a provider with IL authorization shifts that cost to the provider.
GCC High and Azure Government tooling cost Native GCC High and Azure Government tooling carries higher SKUs than commercial. An in-house SOC pays this for its own tooling stack. An MDR provider with established federal customer base spreads the cost across customers.
Continuous monitoring and assessment overhead FedRAMP and FISMA continuous monitoring (monthly POAM updates, quarterly SAR, annual assessment) require dedicated personnel for an in-house SOC. MDR providers handle this for the service authorization; the customer inherits the documentation.
Incident reporting framework alignment Federal incident reporting (US-CERT, CIRCIA, DC3 and DCISE for DIB) requires a defined process. MDR providers operate this process for many customers. In-house SOCs build it from scratch, often without the institutional muscle memory.
Set-aside and contract vehicle access Buying MDR from an 8(a), WOSB, or HUBZone provider opens set-aside acquisition paths. Building in-house does not. For contracting officers facing small-business goal pressure, the buy path can be faster and more politically acceptable.
Personnel security review Cleared analyst hiring requires reinvestigations on a defined cycle (T3, T5, periodic reinvestigation). Provider-staffed analysts go through the provider's program. In-house SOCs carry the reinvestigation burden directly, including the security officer overhead.
When build is right for a federal customer Build can be the right answer when SOC capability is a strategic mission asset (national intelligence, certain DoD components), when classification level exceeds what any commercial MDR can serve, or when the agency mission requires direct control of detection engineering for unique threat models.
When buy is right for a federal customer Buy is the right answer for most federal and DIB customers. The combination of inheritable controls, time-to-coverage, cleared labor availability, and predictable cost makes MDR the default federal procurement model for non-strategic SOC missions.

Common Questions: MDR vs In-House SOC

Can a hybrid approach work? Yes, and it is common. A hybrid model uses MDR for after-hours coverage (nights, weekends, holidays) and an in-house team for business-hours operations and detection engineering. The split lets customers retain capability ownership while solving the 24/7 staffing gap. The contract structure for hybrid is more complex than either pure model.
What is the breakeven scale where build becomes cheaper than buy? There is no single number, but the rough threshold is around ten thousand endpoints or ten million in annual security budget. Below that scale, the fixed costs of an in-house SOC (minimum analyst count, tool licensing, detection engineering) make build uneconomical. Above that scale, MDR price per endpoint can exceed the in-house run rate.
How long does it take to build a federal SOC from scratch? Eighteen to thirty-six months to operational maturity. The first six to twelve months are hiring; the next twelve months are tooling deployment, detection content development, and playbook maturation. Reaching full incident response maturity often takes thirty-six months from program start.
What is the analyst-to-endpoint ratio for an in-house SOC? Industry averages run roughly one analyst per one thousand to three thousand endpoints, depending on telemetry breadth and tool maturity. The ratio is not linear; smaller SOCs have higher overhead per endpoint because of minimum staffing floors.
Can I use a third-party EDR vendor's MDR service? Yes. Many EDR vendors (CrowdStrike, SentinelOne, Microsoft) operate their own MDR services tied to their EDR products. The advantage is integration; the trade is vendor lock-in. Independent MDR providers work across multiple EDR vendors, which preserves customer flexibility.
How does build vs buy affect detection coverage? Mature MDR services typically observe a broader set of attack patterns because they cover many customer environments. In-house SOCs see only their own environment, which limits detection breadth. The gap closes for in-house teams that participate actively in ISACs, share IOCs, and run regular threat-hunt programs.
What if I already invested in SIEM and EDR licenses? Most MDR contracts accommodate customer-licensed EDR and SIEM. The provider integrates with your existing stack rather than requiring replacement. Sunk-cost on tooling is not a reason to keep building in-house if the operating model is otherwise broken.
How does build vs buy affect incident response? An in-house SOC owns the incident response process end-to-end. An MDR engagement may include response actions per contract or may handoff to customer IR teams. For customers without a mature internal IR function, MDR is generally faster to a contained incident.
What is the role of MDR for an in-house SOC team? MDR can extend an in-house SOC team by providing surge support during incident spikes, after-hours coverage, or specialized capabilities (threat hunting, malware reverse engineering). The hybrid model is increasingly common in federal environments.
How does build vs buy affect my CMMC posture? For DIB contractors at CMMC Level 2, MDR from a FedRAMP-authorized provider materially reduces assessment scope. Practices in audit and accountability, incident response, and system and information integrity can be inherited. An in-house SOC must demonstrate each practice independently.
