Managed SIEM Pricing 2026: MSSP Costs, What's Included, and In-House Comparison
Managed SIEM services let you outsource security monitoring to a third-party SOC. For many organisations, this is the most cost-effective path to 24/7 SIEM coverage. But managed SIEM pricing is opaque -- every MSSP quotes differently. This guide provides independent pricing benchmarks and an honest comparison with in-house alternatives.
Managed SIEM Pricing by Organisation Size
Small Business
Under 100 employees
Typically includes: 10-20 log sources, business hours monitoring, monthly reports
Mid-Market
100 - 1,000 employees
Typically includes: 20-100 log sources, 24/7 monitoring, compliance reporting
Enterprise
1,000+ employees
Typically includes: 100+ log sources, 24/7 SOC, custom rules, threat hunting
These ranges represent typical market pricing across multiple MSSPs including UnderDefense, Netsurion, Clearnetwork, and Trustwave. Individual quotes vary significantly based on the SIEM platform used (Splunk-based services cost more than Sentinel-based), the number and complexity of log sources, compliance requirements (HIPAA, PCI-DSS, and SOX monitoring add 20-30% to base pricing), and whether 24/7 or business-hours monitoring is needed.
The managed SIEM market is consolidating rapidly in 2026. Many traditional MSSPs are rebranding as MDR providers, blurring the line between managed SIEM (log-centric monitoring) and MDR (endpoint-centric detection and response). When comparing quotes, ensure you understand whether you are getting true SIEM capabilities (log aggregation, correlation, compliance reporting, long-term retention) or primarily endpoint monitoring with some log integration. The former provides comprehensive security visibility; the latter may leave gaps in network and cloud monitoring.

In-House SIEM vs Managed SIEM: Cost Comparison
For a mid-market organisation with 500 employees, 50 GB/day log volume, needing 24/7 monitoring.
In-House SIEM (Annual)
Managed SIEM (Annual)
The cost difference is striking: managed SIEM at $334,000 per year versus in-house at $995,560 -- a 66% saving. The dominant driver is staffing. Running 24/7 SOC coverage in-house requires a minimum of 5 analysts (to cover shifts, holidays, and sick leave) at an average fully-loaded cost of $130,000 each. A managed SIEM provider amortises SOC analyst costs across dozens of clients, achieving 24/7 coverage at a fraction of the in-house cost.
The trade-off is control and institutional knowledge. In-house SOC teams develop deep understanding of your specific environment, business context, and risk tolerance. They can create highly tuned detection rules that reduce false positives to near-zero for your environment. Managed SIEM analysts handle multiple clients simultaneously and may not understand why an unusual database query at 2 AM is routine for your batch processing or a genuine exfiltration attempt.
The hybrid approach -- using a managed SIEM service for 24/7 monitoring while employing 1-2 internal security staff for escalation handling, custom rule development, and vendor management -- often provides the best balance of cost and capability. At $334,000 per year (including the internal security lead), this model costs less than two in-house analysts alone.
For organisations where even managed SIEM is beyond budget, Managed Detection and Response (MDR) services provide endpoint-focused security monitoring at $3-$15 per endpoint per month. See our partner site mdrcost.com for comprehensive MDR pricing analysis.
How MSSPs Price Managed SIEM
Per-Asset
Charges per monitored device (servers, firewalls, endpoints). Predictable but can be expensive for large estates.
Per-GB
Mirrors SIEM vendor pricing. Transparent but unpredictable if log volume grows.
Per-Employee
Simple proxy for environment size. Easy to budget but may not reflect actual SIEM workload.
Flat-Rate Tier
Fixed monthly fee for defined service level. Best for budget predictability.
When Does Managed SIEM Make Financial Sense?
Managed SIEM is the most cost-effective option for organisations that meet two or more of these criteria: fewer than 500 employees with no existing SOC team; compliance requirements (PCI-DSS, HIPAA) that mandate 24/7 monitoring and regular reporting; log volume under 200 GB/day; security budget under $500,000 per year; or difficulty recruiting and retaining security analysts in your market.
In-house SIEM becomes more cost-effective when: you exceed 500+ employees with complex, heterogeneous environments; you already employ 3+ security analysts; your log volume exceeds 200 GB/day (where managed SIEM pricing accelerates); you need deep customisation of detection rules and response playbooks; or your security maturity level requires advanced threat hunting that most managed services do not provide at standard pricing tiers.
The decision is not permanent. Many organisations start with managed SIEM to establish baseline security monitoring, then transition to in-house SIEM after 2-3 years once they have built a security team, understand their log sources, and can justify the in-house investment. This staged approach reduces risk and provides data to support the business case for in-house SIEM. See our SIEM ROI guide and cost-by-size analysis for more on financial planning.
Managed SIEM Pricing FAQ
How much does managed SIEM cost per month?
Managed SIEM pricing typically ranges from $3,000-$5,000 per month for small businesses (under 100 employees, fewer than 20 log sources), $5,000-$15,000 per month for mid-market organisations (100-1,000 employees, 20-100 log sources), and $15,000-$50,000+ per month for enterprises (1,000+ employees, 100+ log sources). These prices typically include 24/7 monitoring, alert triage, incident escalation, and basic reporting. Advanced services like custom detection rules, forensic investigation, and incident response are usually priced separately or available in premium tiers.
Is managed SIEM cheaper than running SIEM in-house?
For organisations with fewer than 500 employees, managed SIEM is almost always cheaper than running an equivalent SIEM in-house. In-house SIEM requires a minimum of 2-3 dedicated analysts for business-hours coverage ($260,000-$390,000 in salaries alone), plus SIEM licensing ($50,000-$200,000+), infrastructure costs, and ongoing tuning and maintenance. A managed SIEM provider delivers comparable or better coverage at $60,000-$180,000 per year by amortising analyst costs across many clients. The crossover point where in-house becomes more cost-effective typically occurs around 300-500 employees with 100+ GB/day log volume.
What is included in managed SIEM services?
Standard managed SIEM services typically include: SIEM platform licensing and hosting, log source onboarding and configuration, 24/7 security monitoring by trained SOC analysts, alert triage and false-positive reduction, incident escalation per defined playbooks, monthly security reports and compliance documentation, and basic detection rule management. Premium tiers may add: custom detection rule development, threat hunting, forensic investigation, incident response, vulnerability management integration, and executive briefings. Always confirm what is included vs priced separately before signing.
What is the difference between managed SIEM and MDR?
Managed SIEM focuses on log aggregation, correlation, and compliance reporting -- the SIEM platform is the core technology, and the managed service wraps monitoring and alert handling around it. Managed Detection and Response (MDR) focuses on threat detection and response outcomes, using a combination of endpoint detection (EDR), network monitoring, and sometimes SIEM data. MDR typically provides more active threat hunting and incident response, while managed SIEM provides better compliance reporting and log management. Managed SIEM costs $3,000-$50,000+ per month; MDR typically costs $3-$15 per endpoint per month. Many organisations benefit from MDR more than managed SIEM. Compare MDR pricing at mdrcost.com.
How do MSSPs price their managed SIEM services?
MSSPs use four main pricing models for managed SIEM: per-asset (charging $15-$50 per monitored asset per month, where assets include servers, firewalls, and network devices), per-GB (charging $5-$15 per GB of log data ingested per day, similar to SIEM vendor pricing), per-user/per-employee (charging $5-$25 per employee per month as a simpler proxy for environment size), and flat-rate tiers (bundled packages at fixed monthly rates for defined service levels). Per-asset is the most common model, followed by flat-rate tiers. The best model depends on your asset count, log volume, and growth trajectory.
