When MSSP beats build
Choose an MSSP for immediate 24/7 detection and containment.
The provider handles shift coverage and tooling integration.
When build beats MSSP
Build in‑house when regulation or internal controls demand full custody of logs and evidence.
Long-term marginal costs fall with scale.
An anonymized 350-seat SaaS SMB illustrates costs and timing.
They retained an MSSP for 24/7 detection while hiring for an internal SOC.
Year 1 MSSP fees were approximately $210k, plus $40k in vendor governance, totaling $250k.
They hired two senior engineers and one junior analyst.
Their Year 2 run rate rose to $360k including salaries and licenses.
Including amortized one-time integration of $45k, cumulative three-year spend showed break-even near month 34.
MTTD dropped from about 18 hours before the MSSP to about 4 hours during MSSP coverage.
It later stabilized at about 6 hours after the in-house transition.
Incident count with successful containment fell about 38% year-over-year.
Use anonymized metric-driven vignettes like this to set realistic board expectations.
They clarify cost timing, incident reduction, and hybrid ramp value.
Choose an MSSP
This section explains when to choose a Managed Security Service Provider.
It lists practical controls to request in contracts.
The MSSP option fits SMBs that need rapid coverage and predictable operating costs.
Expect a faster time to detect and initial protection.
The most common error at this point is comparing only the headline monthly fee.
Add ingestion, connectors, and artifact fees to avoid surprises.
Many MSSP proposals include optional line items.
Negotiate explicit inclusions for onboarding, log export, and incident artifact delivery.
Key contract items to demand
List explicit prices for onboarding, per‑GB log ingestion, API connectors, and forensic hours.
Require defined export formats and transition assistance.
Operational realities with MSSP
Plan for 0.25–1.0 FTE internal vendor manager.
That role handles ticketing, playbook validation, and escalations with the provider.
Build in‑house zero trust
This section covers realistic costs for creating an internal Zero Trust capability.
It also highlights hidden staffing demands.
Building in‑house suits SMBs with sustained budgets and hiring capacity.
Expect a longer ramp and larger year‑one capital expense.
A typical case: a 350‑seat SaaS business lacked overnight coverage and hired two engineers while keeping an MSSP retainer.
Outcome: improved audit readiness and lower marginal costs after year two.
What most guides omit is the steady cost of playbook tuning and employee churn.
Budget continuous training and retainer‑level incident drills.
Core hires and salaries
Expect SOC Analyst salaries of $80k–$130k and Senior Engineers $120k–$200k in the United States.
Shift coverage multiplies headcount needs.
Budget SIEM, EDR, and identity licenses upfront.
One‑time engineering for integration is typically $5k–$75k depending on complexity.
Consider a hybrid path
Hybrid blends MSSP operational scale with retained internal control over critical systems.
This path reduces risk and spreads costs.
Hybrid fits when compliance demands custody but budget limits full in‑house staffing.
It lets teams adopt Zero Trust gradually.
A common deployment: MSSP covers 24/7 monitoring while internal staff own IAM, PAM, and incident runbooks.
Overlap runs 2–3 months during cutover.
How to structure hybrid roles
Retain 0.5–1.5 internal FTEs for vendor governance and identity ownership.
Keep MSSP for telemetry and escalation support.
Cost behavior for hybrid
Expect dual costs during overlap: 1–3 months of duplicate licenses and engineering hours.
Budget 5–15% of annual license cost for cutover.
How to choose according to situation
Provide a repeatable scoring method and a practical TCO calculator.
Use the outputs for board approval and RFPs.
Score each option on budget, time to protect, compliance demand, and internal skills.
Assign 1–5 for each criterion and total the scores.
Use three budget bands with sample TCO ranges.
For 50, 200, and 500 seats, show realistic all‑in annual totals.

Decision scorecard
Weight budget 30%, compliance 30%, time 20%, control 20%.
Choose the option with the highest weighted score.
Use break‑even month to assess migration timing.
Estimated three‑year break‑even for an SMB shifting from MSSP to in‑house typically occurs between year two and year four. For 200 seats, expect break‑even around 30–36 months when internal hiring and license amortization are included.
Illustrative TCO examples (worked numbers). Below are concise, worked TCO examples you can paste into a board pack.
They show how line items add up by SMB size using conservative assumptions for tooling, telemetry, and staffing.
- Assumptions:
- EDR $50 per endpoint/year
- IAM/SSO $6 per user/month
- SIEM ingestion $0.50 per GB ingested
- telemetry per user ~6 GB/month
- MSSP headline fee varies by coverage
- Example A (50 seats):
- EDR $2,500
- IAM $3,600
- SIEM ingestion 3,600 GB/year × $0.50 = $1,800
- MSSP headline $18,000/year → MSSP all‑in ≈ $25,900/year
- Example B (200 seats):
- EDR $10,000
- IAM $14,400
- SIEM 14,400 GB/year × $0.50 = $7,200
- MSSP headline $36,000/year → MSSP all‑in ≈ $67,600/year
- Example C (500 seats):
- EDR $25,000
- IAM $36,000
- SIEM 36,000 GB/year × $0.50 = $18,000
- MSSP headline $75,000/year → MSSP all‑in ≈ $154,000/year
For in‑house compare by adding SOC FTEs (e.g., 1 FTE ≈ $120k/year fully loaded), SIEM license one‑time amortized, and a conservative $25k/year for integration and maintenance.
These examples show how telemetry volume and MSSP headline fees drive crossover points.
What nobody tells you
This section highlights hidden contractual and operational traps that skew TCO and compliance outcomes.
Headline MSSP fees frequently omit log ingestion, connector engineering, and per‑artifact costs.
Model those as recurring line items.
Switching vendors can create multi‑year sunk costs.
Account for reconfiguration engineering and duplicate licensing during cutover.
Hidden compliance costs by regulation
PCI and SOC 2 commonly require preserved evidence and signed attestations.
Providers may bill artifact delivery separately.
Include artifact delivery clauses.
Migration and lock‑in
Plan for 50–500 engineering hours to migrate playbooks and connectors depending on environment.
Negotiate transition assistance into the contract.
Zero trust cost mapping by control domain
Map each Zero Trust control to budget buckets and expected incident impact.
Prioritize investments by incident reduction potential and audit evidence needs.
NIST SP 800‑207 defines the core principles of Zero Trust.
Align spend to those control domains when mapping costs and evidence.
The IBM Cost of a Data Breach Report 2023 found average breach costs of $4.45M.
That figure shows why detection investments deliver measurable ROI.
IAM and PAM costs
IAM and SSO run approximately $3–$8 per user per month.
PAM solutions range widely, from $10k to $100k annually.
Endpoint and EDR costs
Expect EDR licensing of $20–$120 per endpoint per year.
Managed EDR via MSSP adds a monitoring fee per endpoint per month.
Network segmentation and ZTNA costs
ZTNA and SASE services typically cost $8–$40 per user per month.
Microsegmentation tooling can require $25k–$250k depending on environment size.
SIEM, telemetry, and SOAR costs
SIEM license and ingestion can range from $10k to $200k annually.
Per‑GB ingestion pricing often applies and scales with telemetry volume.
Estimated control cost example: For 200 seats, implementing IAM, EDR, and SIEM with moderate retention typically costs $90k–$220k in year one. Proper tuning reduces mean time to detect by 20–50%.

The infographic helps visualize where the budget typically concentrates.
It also shows where marginal reductions in incident scope occur.
Choose an MSSP when speed and a predictable operating expense matter.
Plan a twelve to thirty-six month roadmap to regain internal control after onboarding.
Build in‑house only if budget and talent support continuous engineering beyond year two.
Frequently asked questions
What is the true TCO for a 200‑seat SMB?
Expect all‑in annual costs of $90k–$336k for MSSP and $220k–$500k for first year in‑house.
Model three years and include onboarding, log ingestion, licenses, and vendor management FTEs.
Use sensitivity scenarios to show best and worst cases to executives.
How large is the hidden log ingestion cost?
Log ingestion pricing is typically quoted per GB ingested with wide unit variation.
Expect a typical range of roughly $0.10–$2.00 per GB ingested and confirm the unit.
Clarify whether vendors charge on peak day, daily average, or monthly totals.
Can an MSSP satisfy PCI or SOC 2 audits?
Yes, but only with explicit contract clauses that provide evidence and attestations.
Confirm evidence delivery format, retention windows, and the right to export raw logs.
Budget for joint control attestations and audit support hours.
How much does vendor switching cost?
Plan for 50–500 engineering hours and 1–3 months of duplicate licensing during migration.
Normalization of logs can cost $5k–$50k depending on diversity.
Require raw log export in a standardized format to reduce professional services fees.
How to evaluate MSSP SLAs effectively?
Focus on MTTD, MTTR, incident ownership, and artifact delivery times.
Tie service credits to these metrics and verify them monthly.
Ask for historical MTTD and MTTR numbers and include audit clauses.
Not all guidance here applies to micro startups with minimal digital footprint. If the environment is limited to a few SaaS subscriptions and no regulated data, basic SaaS security and native vendor controls can suffice without a SOC or MSSP contract.
Actionable synthesis and next steps
Provide an executable plan to prepare an RFP and board approval packet within 30 days.
Step 1: Populate a CSV with seats, estimated log GB/day, desired retention, and salaries.
Produce a three‑year TCO and the break‑even month.
Step 2: Issue an RFP with line‑item pricing for onboarding, log ingestion, connectors, forensic hours, and transition assistance.
Require a sample evidence package for audits.
Step 3: Pilot IAM and EDR for 4–8 weeks with an MSSP or in‑house PoC.
Track MTTD, false positives, and remediation time and use pilot metrics in the board packet.
Negotiation checklist (copy into RFP):
- Line items: onboarding, connectors, per‑GB ingestion, per‑user licenses, forensic hourly rates.
- Transition: minimum 40–120 hours of transition assistance included at no charge.
- Evidence: raw log export rights, artifact format, and retention prices fixed for contract term.
- Service credits: tied to MTTD, MTTR, and artifact delivery failures.
