Managed Cybersecurity Services: What You Actually Get for the Money

TL;DR: Managed cybersecurity services bundle a 24/7 SOC, SIEM, EDR, vulnerability management, and incident response under one monthly contract. For a 50 to 500 person company, expect $8K to $20K per month. Building the same in-house runs roughly $500K per year once you count two analysts, tooling, and attrition risk.

Who This Article Is For

If you're a CIO, IT Director, or Ops Lead at a 50 to 500 employee company and you can't staff a 24/7 security team internally, this is your buyer's guide. I've run 50+ compliance remediations across SOC 2, HIPAA, and CMMC, and the same MSSP contract mistakes show up almost every time. We'll cover what's actually in a managed cybersecurity services contract, what gets quietly omitted, how to price it against an in-house build, and how to hold your provider accountable after the ink dries.

The core deliverables you should expect: SIEM (Security Information and Event Management) monitoring, EDR (Endpoint Detection and Response), firewall management, vulnerability management, patch management, identity and access management (IAM), and a written incident response SLA. Anything less isn't a security service. It's a dashboard subscription.

What's Actually Included (and What's Quietly Left Out)

A real managed cybersecurity services contract covers six operational layers. Here's what each one costs when priced separately, so you can sanity-check any bundled quote.

SIEM monitoring. Splunk Cloud runs on a per-GB ingestion model. For a 200-person company producing 20 to 50 GB of logs per day, that's roughly $50K to $150K per year in licensing alone before anyone looks at an alert. Alternatives like Microsoft Sentinel or Elastic can lower ingestion costs, but you'll pay in tuning time.

EDR. CrowdStrike Falcon lists around $15 to $25 per endpoint per month depending on modules. SentinelOne Singularity Core sits closer to $6 to $8 per endpoint per month at base tier. The tradeoff isn't brand loyalty. CrowdStrike generally wins on detection fidelity and threat intel breadth. SentinelOne wins on price and rollback automation. Pick based on your environment, not the sales deck. Our managed EDR guide breaks the choice down further.

Firewall management. Rule review, change management, log forwarding to the SIEM. This is boring and vital. Most breaches we investigate touched a firewall rule nobody had audited in 18 months.

Vulnerability management. Continuous scanning with Tenable, Qualys, or Rapid7, plus a remediation SLA tied to CVSS severity. Ask your MSSP what their remediation SLA is for a CVSS 9.0+ vulnerability. If they can't tell you in minutes, they don't have one.

Patch management. Windows, Linux, and third-party apps. Tie this to the vulnerability scan results or you're scanning for problems nobody plans to fix.

IAM. Okta Workforce Identity runs about $6 per user per month for the SSO tier, more if you add lifecycle management or Adaptive MFA. Duo and Microsoft Entra ID are the common alternatives.

What generic packages routinely omit: cloud security posture management (CSPM) for AWS and Azure, insider threat detection, OT/ICS coverage for manufacturing or utilities, and DNS-layer filtering. Ask specifically. Don't assume.

MDR vs. MSSP: Stop Conflating Them

Most buyers use these interchangeably. They shouldn't. MDR (Managed Detection and Response) means active threat hunting plus response actions on your endpoints. MSSP (Managed Security Service Provider) historically means alert forwarding and reporting. A real MDR contract lets the vendor isolate an infected host at 2am without waiting for your approval. A standard MSSP contract sends you a ticket and hopes you're awake. Read the statement of work carefully.

Hidden SLA Red Flags: Read This Before You Sign

Here's where I've seen more post-breach disputes than anywhere else. The contract language kills you.

Watch for "commercially reasonable efforts." This phrase means no enforceable response time. If your provider takes six hours to acknowledge a critical alert, you have no recourse. Demand a hard mean-time-to-respond (MTTR) in minutes for critical severity alerts, written into the master agreement, not the appendix.

Named liability cap in dollars. Many contracts cap liability at "fees paid in the trailing 12 months." If you pay $150K a year and a missed alert leads to a $4.9M breach (the IBM Cost of a Data Breach Report 2024 pegs the global average at $4.88M), that cap won't cover your legal fees. Push for a named dollar figure that reflects the risk transfer you thought you were buying.

Explicit on-site IR commitment. Remote-only IR is fine for commodity malware. It's inadequate for ransomware, wire fraud investigations, or anything involving law enforcement. CyberStar's public commitment is on-site the next business day after a confirmed breach. If you get hit Thursday night, we're in your office Friday morning. Ask any candidate MSSP to put a similar window in writing.

Auto-renewal traps. Read the exit notice clause. Ninety-day notice windows buried in an appendix are standard, and they'll trap you into another year if you miss the date.

Before signing, ask for the last three redacted incident post-mortems. Any provider that can't share sanitised examples has either never handled a real incident or is embarrassed by how they handled the last one.

True Cost Comparison: Managed vs. In-House

Here's the honest math for a 200-person company. We break this down more deeply in our managed security services vs in-house analysis, but the summary matters.

In-house build, annualised:

• Two SOC analysts at $95K base each, plus 1.3x benefits multiplier: ~$247K
• SIEM licensing (Splunk Cloud, mid-market log volume): ~$100K
• EDR licensing (CrowdStrike, 250 endpoints at $18): ~$54K
• IAM (Okta, 200 users at $6): ~$14K
• IR retainer (Mandiant, Kroll, or similar): ~$25K to $50K
• Recruiting cost at 20% of first-year salary: ~$19K one-time per hire
• Training, certifications, tooling extras: ~$20K

You're at roughly $460K to $500K per year, and that assumes you can hire and keep two analysts. According to CyberSeek's 2024 workforce data, there are roughly 469,000 open cybersecurity jobs in the US. The unemployment rate in the field is effectively zero. Losing one analyst three weeks before your SOC 2 audit is not a hypothetical. It's a Tuesday.

MSSP equivalent: $8K to $20K per month, or $96K to $240K per year, for 24/7 monitoring, SIEM, EDR, IAM management, vulnerability scanning, and basic IR hours. Roughly half the fully-loaded cost, and you don't inherit the hiring risk.

The Co-Managed Middle Path

For 100 to 300 employee companies with an existing IT lead, co-managed security is often the right answer. You keep one internal security lead, the MSSP provides tooling, 24/7 coverage, and an IR bench. Your lead owns strategy and vendor management. The MSSP owns the graveyard shift. This model has been growing quickly, and for good reason. It's the pattern I recommend most often for mid-market companies with a compliance mandate but not enough headcount budget for a full team.

Compliance Gaps Generic MSSPs Miss

This is where commodity providers fall apart. Every framework has specifics that a generalist won't touch.

HIPAA. The Security Rule at 45 CFR §164.312 requires specific technical safeguards including audit controls, access controls, and transmission security. Audit logs must be retained for six years under §164.316(b)(2)(i). We regularly see MSSPs configure 90-day log retention because that's their default, and clients discover the gap during their first OCR audit response. Confirm ePHI encryption in transit and at rest is validated, not just enabled.

SOC 2 Type II. The AICPA Trust Services Criteria CC6.1 (logical access) and CC7.2 (system monitoring) require continuous evidence collection across the audit window. Monthly summary reports don't cut it. Your auditor will pull continuous logs. If your MSSP only produces summaries, you'll rebuild the evidence chain the week before the audit. Not fun. Our SOC 2 certification cost piece covers the budget impact of this in more detail.

CMMC 2.0 Level 2. Requires NIST SP 800-171 controls including IR.3.098 (incident response plan testing). Most commodity MSSPs don't run tabletop exercises as part of the base retainer. Ask specifically.

PCI-DSS v4.0. Requirement 10 (log management) and 11.4 (penetration testing) changed materially from v3.2.1. Confirm your MSSP has updated their playbooks. Some are still running v3 workflows.

When you evaluate any provider, ask: which certifications do your SOC analysts hold? Acceptable answers include CISSP, CISM, QSA for PCI, and HITRUST CCSFP for healthcare. Vague answers are the answer.

Holding Your MSSP Accountable After Onboarding

Almost every buyer's guide stops at vendor selection. That's the wrong place to stop. Relationships fail in month seven, not month one.

Demand a monthly scorecard with five concrete KPIs:

1. Mean time to detect (MTTD) per severity tier. Ponemon and the Verizon 2024 Data Breach Investigations Report show mean dwell times for undetected intrusions still measured in weeks industry-wide. Your MSSP should be measured in minutes for critical alerts.
2. Mean time to respond (MTTR). Tied to the SLA you negotiated in section 3.
3. False positive rate on critical alerts. If it's above 30%, your analysts are drowning and will miss the real one.
4. Patch SLA compliance rate. Percentage of critical vulnerabilities patched within the contractual window.
5. Vulnerability scan coverage. Percentage of assets scanned versus your asset inventory. If coverage is 78%, you're paying for security on 78% of your environment.

Set a 90-day baseline, then benchmark quarterly. Require QBRs with a named technical account manager, not just an account executive. If any provider resists written KPIs in the contract, that's your answer.

On threat intel: generic feeds are noise. Ask for monthly briefings tied to your vertical. FS-ISAC for financial services, H-ISAC for healthcare, MS-ISAC for state and local government. On pen testing: annual external tests minimum, and results should feed directly into the MSSP's remediation queue with an SLA, not sit in a PDF nobody reads.

How CyberStar's 5-Star Cyber Shield Maps to This

We structure engagements around five pillars, and each maps to the service layers above.

• Protect: firewall management, patch management, Okta-based IAM, continuous vulnerability management.
• Detect: 24/7 SIEM on Splunk or Sentinel depending on your stack, EDR (CrowdStrike or SentinelOne based on budget and environment), MDR threat hunting.
• Recover: published IR SLA with on-site response the next business day after a confirmed breach, plus Veeam backup validation (Veeam runs roughly $10 to $15 per workload per month for mid-market Data Platform Foundation tier).
• Comply: SOC 2, HIPAA, and CMMC gap assessments built into onboarding, continuous evidence collection for audit readiness. If you're weighing providers, our how to choose managed security services guide walks the evaluation process in detail.
• Train: quarterly phishing simulations via KnowBe4 (roughly $20 to $35 per user per year) plus tabletop exercises that count toward CMMC IR.3.098 and SOC 2 CC9.2.

We don't do commodity break-fix. Every engagement is compliance-anchored, and we publish our IR SLA because we're willing to be held to it. If you also need ransomware protection for mid-market companies or HIPAA compliant managed IT, those wrap into the same shield, not separate contracts. For teams evaluating standalone SOC options, our outsourced SOC options breakdown is worth a read.

Frequently Asked Questions

What is the difference between an MSSP and MDR? An MSSP typically forwards alerts and generates reports. An MDR service actively hunts threats and takes response actions on your endpoints, including host isolation, without waiting for you to approve each step. If your contract doesn't authorise the vendor to contain a compromised host at 2am, you have an MSSP, not MDR.

How much do managed cybersecurity services cost for a 100-person company? Expect $6K to $12K per month for a covered scope including 24/7 SIEM, EDR on all endpoints, IAM management, vulnerability scanning, patch management, and basic IR hours. Add-ons like CSPM, DLP, or dedicated threat hunting can push it higher. Anything under $4K per month for a 100-person company almost certainly excludes 24/7 human coverage.

Do managed cybersecurity services cover HIPAA and SOC 2 compliance? Some do, most don't fully. Generic packages give you the tools but not the continuous evidence collection auditors demand. Confirm the provider maps their service specifically to HIPAA §164.312 and SOC 2 CC6.1 / CC7.2, and that they produce audit-ready evidence, not summary reports.

What happens if we get breached, what does the MSSP actually do? It depends entirely on the contract. Best case: containment within minutes, forensic collection, on-site response the next business day, coordination with your legal and insurance teams. Worst case: an email ticket and a referral to a third-party IR firm that bills you separately at $500 to $900 per hour. Read the IR clause carefully.

Can we keep our internal IT team and still use a managed cybersecurity provider? Yes, and for mid-market companies that's usually the smart move. Co-managed security keeps your internal lead in charge of strategy and vendor management, while the MSSP owns 24/7 coverage, tooling, and IR bench depth. Works best in the 100 to 300 employee range where you have an IT team but not a dedicated security function.
