Outsourced IT Security Services Companies: What You Actually Pay For in 2025
TL;DR: What Outsourced IT Security Actually Gets You
Outsourced IT security services companies (MSSPs) run your SOC, SIEM, EDR, and compliance monitoring on your behalf, typically $3,000 to $15,000 per month for mid-market firms. They shift operational burden, not liability. You still own audit outcomes and breach costs. Best fit: 50 to 500 employees without a dedicated internal security team.
The honest caveat most vendors won't say out loud: hiring an MSSP doesn't make your board any less responsible when a Type II auditor asks for evidence. It just means you have someone to call at 2am.
According to Gartner's Magic Quadrant for MSSPs coverage, mid-market pricing has crept up 8 to 12% year over year since 2022. Building the equivalent internally is worse: a three-person SOC (analyst, engineer, manager) runs roughly $350,000 to $450,000 in salary alone before tooling, per (ISC)² Cybersecurity Workforce Study 2023 data on US analyst comp.
The 5 Core Services Any MSSP Should Cover
If a vendor can't name specific SLAs against each of these, walk.
1. 24/7 SOC with real SLAs. Alert triage under 15 minutes for critical severity. Human escalation to your on-call inside an hour. "We monitor" isn't a service. Ask them what happens between 11pm Saturday and 6am Sunday, and get the answer in writing.
2. SIEM management, tuned. Splunk, Microsoft Sentinel, or Elastic. The tool matters less than what they do with it. Microsoft Sentinel runs consumption-based pricing around $2.46/GB ingested per the Azure pricing page. Splunk Enterprise Security lands higher, often $150 to $200+ per GB/day at mid-market volumes. A vendor who deploys defaults and walks away is why the average dwell time is 204 days.
3. EDR deployment and management. CrowdStrike Falcon Pro runs roughly $15 to $25 per endpoint per month at mid-market volumes. SentinelOne Singularity Core sits closer to $6 to $12. CrowdStrike wins on threat intel quality and Falcon Complete MDR. SentinelOne wins on price and on-prem/air-gapped support. Both are strong. The right pick depends on your stack, not on the MSSP's rebate agreement.
4. Firewall management and config drift detection. Not uptime pings. Actual weekly review of rule changes, orphaned rules, and shadow allows.
5. Vulnerability assessments plus periodic penetration testing. Monthly authenticated scans (Tenable, Rapid7, Qualys) are not the same as an annual manual pen test. You need both. See our full breakdown of penetration testing cost and benefits for what to budget.
Layer on compliance mapping to NIST CSF, SOC 2, HIPAA, or CMMC. Ask the vendor which framework their compliance lead has actually shipped audits against. "We support all of them" usually means they've done none deeply.
Hidden Risks Vendors Won't Put in the Brochure
Here's where I've watched deals go sideways.
Shared-resource dilution. During a widespread event (think MOVEit, Log4Shell, or the 2024 CrowdStrike outage), your MSSP's SOC analysts are triaging 40 to 80 clients at once. Analyst-to-client ratios at the large branded providers can hit 1:50 during business hours and worse overnight. Ask directly: "What's your surge staffing plan and where's it documented?"
Data sovereignty. Where do your SIEM logs actually live? Cross-border log storage is easy to inherit without noticing, and it is fine for most workloads until a healthcare or public sector contract makes residency a contractual term. Get the region in writing and confirm BAA coverage.
Detection vs. remediation SLA gap. Most MSSP contracts guarantee detection and notification. They do not guarantee remediation. That gap is exactly where breach costs land. IBM's Cost of a Data Breach Report 2023 put the global average at $4.45M, and containment time was the single biggest cost driver.
Exit fees and data portability. Getting out of a 36-month MSSP contract in month 14 typically costs $20,000 to $60,000+ in early termination plus data extraction fees. Ask for the exit schedule before signing. If they won't provide one, that's your answer.
Integration debt. Wiring Microsoft 365, Entra ID, on-prem AD, and your existing EDR into a new MSSP's SIEM realistically eats 40 to 80 hours of billable work. Bake that into year one, not "onboarding, no charge."
Full Outsource vs. Hybrid: A Decision Framework
Cookie-cutter recommendations kill budgets. Use this.
Under 100 employees, no security staff: Full MSSP outsourcing. You can't hire a three-person SOC for less than the annual salary spend, and one person can't cover 24/7 anyway.
100 to 300 employees, 1 to 2 IT staff: Hybrid. Keep helpdesk and endpoint hygiene in-house. Outsource SOC, SIEM, and compliance advisory. This is where most of my clients sit. Read our managed security services vs in-house TCO guide for the full model.
300 to 500 employees with an approaching SOC 2: Co-managed SIEM. Arctic Wolf and Secureworks Taegis are built for this. MSSP handles detection and hunt; your team takes remediation tickets. Arctic Wolf pricing lands roughly $15 to $30 per user per month at this range depending on modules.
Healthcare (HIPAA): You need PHI-aware log handling, signed BAAs, and someone who knows what "minimum necessary" means in a SIEM context. Most generic MSSPs don't. Our HIPAA compliant managed IT services breakdown covers the specifics.
Manufacturing with OT/ICS: Almost no branded MSSP has real Purdue Model or Modbus/DNP3 expertise. Ask them to name their ICS engineer. If they can't, they're guessing.
CMMC Level 2 contractors: You need an MSSP who can produce SSP and POA&M documentation aligned to NIST SP 800-171 Rev 2, not just run a SIEM.
How to Hold an MSSP Accountable After You Sign
The contract is the easy part. Governance is where most mid-market clients drop the ball.
Require a monthly Security Review Report with these KPIs, not vendor marketing screenshots:
- Mean time to detect (MTTD)
- Mean time to respond (MTTR)
- Total alerts triaged, split by severity
- False positive rate by rule category
- Open vulnerability age (critical, high, medium buckets)
Red flag one: MTTR above four hours for critical alerts. Set that against the industry's 204-day dwell time and the size of the prize is obvious, but closing the gap depends on detection rules written for your environment rather than the defaults that shipped with the platform. Every MSSP has a SOC. Not every SOC is watching.
Red flag two: No named engineer. If your escalation path is support@vendor.com, you're a commodity account.
Red flag three: Refusal to give you raw log query access. You should always be able to audit what they're seeing.
Run a tabletop exercise within 90 days of go-live. NIST CSF 2.0's Respond function (RS.CO) explicitly requires that "incident response information is shared with designated internal and external stakeholders." If your MSSP can't walk through a ransomware scenario with your leadership team, they're not ready for the real one.
Real Total Cost of Ownership: Beyond the Monthly Invoice
The headline monthly fee is usually 60 to 70% of your actual first-year spend.
Add:
- Onboarding labour: 40 to 120 hours at $150 to $250/hour, either MSSP-billed or absorbed by your team
- Tool licensing pass-through: some MSSPs bundle CrowdStrike or SentinelOne, others charge list plus a 15 to 20% margin
- Staff retraining: budget 8 to 16 hours for your IT team to learn the ticket workflow and escalation paths
- Integration and connector work: SaaS log sources add up fast
Ask a prospective MSSP what they would remove from your stack, not just what they would add. Duplicated tooling is common and expensive, and a provider who never proposes retiring anything is telling you something about how they are paid. Vendors love selling you overlapping products. An honest MSSP will cut your bill before adding to it.
Compare TCO against the $4.45M IBM breach average. On any reasonable probability model, prevention wins. But only if you actually measure it.
How CyberStar Structures This Differently
I'll keep this short because you didn't come here for a pitch.
- Published IR SLA. If you get breached on a Thursday night, we're on-site Friday morning. That's in the contract, not the sales deck.
- Compliance-first scoping. Every engagement starts by mapping your audit target (SOC 2 Type II, HIPAA, CMMC Level 2) before we recommend a single tool. See our SOC 2 readiness playbook for how we approach this.
- Vendor-agnostic. CrowdStrike, SentinelOne, or Microsoft Defender based on your environment. Not on our margin.
- Named engineer, not a queue. One assigned lead who knows your stack.
- No long lock-in. Month-to-month available after the 90-day onboarding period.
What you should be buying is evidence: documented incident response testing, tabletop records with dates on them, and reporting an underwriter or an auditor can read without translation. That's the outcome you're paying for. Not a logo on a dashboard.

FAQs: Outsourced IT Security Services
What does an outsourced IT security company actually do day-to-day? Monitor SIEM alerts, manage EDR (CrowdStrike, SentinelOne, Defender) across endpoints, tune firewall rules, run monthly vulnerability scans, and escalate confirmed incidents to your team with a remediation plan. Better providers also run quarterly tabletop exercises and monthly control reviews.
How much do outsourced IT security services cost? For 50 to 300 employees, expect $3,000 to $12,000 per month for full-service MSSP coverage. Co-managed or monitoring-only tiers land $1,500 to $4,000. Add 40 to 120 hours of onboarding labour in year one.
Can an MSSP make us SOC 2 compliant? They cover the technical controls, roughly CC6 (logical access) and CC7 (system operations) under the AICPA Trust Services Criteria. SOC 2 also requires policy documentation, HR controls, vendor management, and change management, which your MSSP won't own. You need a compliance advisor working alongside them.
What's the difference between an MSSP and an MDR provider? MSSPs manage your tools and alert queue. MDR providers (CrowdStrike Falcon Complete, SentinelOne Vigilance, Arctic Wolf) actively investigate, contain, and often remediate threats without waiting for your approval. Falcon Complete typically prices $8 to $15 per endpoint per month above base Falcon licensing.
How long does onboarding an outsourced IT security provider take? Realistic timeline for a 100 to 300 person company is 30 to 60 days: two weeks for log source integration, two weeks for SIEM rule tuning, two weeks for runbook development and tabletop exercise. Anyone promising 7-day onboarding is skipping the tuning.
Should we outsource security if we already have an internal IT team? Usually yes, in a co-managed model. Your team knows your business better than any vendor. An MSSP adds 24/7 coverage and specialised threat expertise your two-person IT team can't sustain. Read how to choose managed security services for the decision matrix.
