24/7 SOC With AI SIEM: Build or Outsource
Operating a true 24 by 7 Security Operations Center in 2025 is no longer optional for mid to large Indian enterprises. The combination of ransomware, identity abuse, cloud lateral movement, and API-based attacks means detection delays directly translate into financial impact. AI SIEM platforms now form the foundation of modern SOC operations, but many enterprises face a critical decision. Should the SOC be built internally or outsourced to a managed provider.
This guide breaks down real cost structures, analyst headcount requirements, tooling differences, coverage models, and the operational risks of both approaches. It concludes with a practical recommendation matrix to guide enterprise security leaders.

Cost Comparison: In House SOC vs Outsourced SOC
In House 24 by 7 SOC Cost Structure
An internal SOC runs on both capital expenditure and recurring operational expense.
Key cost components include:
AI SIEM licensing and log ingestion
UEBA, SOAR, NDR, and threat intelligence modules
Endpoint and network telemetry tools
High availability storage and compute
SOC infrastructure and secure workspace
Analyst salaries across three shifts
Training, certifications, and retention programs
For a 1000 employee enterprise in India, real world monthly cost typically ranges between:
Technology stack: 4.5 to 8.0 lakh
Analyst salaries and overhead: 8.0 to 14.0 lakh
Total monthly operating cost: 12.5 to 22.0 lakh
Outsourced 24 by 7 SOC Cost Structure
An outsourced SOC bundles:
Full AI SIEM platform
Incident response workflows
Detection engineering
Threat hunting
SLA-backed monitoring
Compliance reporting
For the same 1000 employee enterprise, outsourced models typically range between:
4.0 to 8.0 lakh per month depending on telemetry volume and response depth
This makes outsourced SOC between 40 to 60 percent more cost efficient at scale.
Analyst Headcount Required for 24 by 7 Operations
In House SOC Staffing Model
A minimum 24 by 7 SOC requires:
6 to 9 Tier 1 analysts for three shifts
2 to 3 Tier 2 analysts
1 to 2 threat hunters
1 SOC manager
1 detection engineer
Minimum operational team size ranges between 11 to 15 skilled professionals.
This structure becomes difficult to maintain due to:
Hiring delays
High attrition
Uneven skill distribution
Burnout and fatigue
Outsourced SOC Staffing Model
Outsourced SOC providers:
Spread analysts across multiple customers
Maintain specialized detection engineers
Operate dedicated threat hunting teams
Ensure coverage continuity during attrition
The enterprise does not carry recruitment, certification, or retention risk.
Tooling Requirement Differences
In House SOC Tooling Stack
A build model usually requires purchasing and integrating:
AI SIEM
Endpoint detection and response
Network detection and response
Threat intelligence feeds
SOAR automation
Case management
Integration effort becomes a major operational burden.
Outsourced SOC Tooling Stack
Most managed providers operate:
A unified AI SIEM platform
Integrated detection and response tooling
Prebuilt playbooks
Threat intelligence pipelines
Automated reporting for compliance
The enterprise consumes outcomes rather than managing tools.
24 by 7 Coverage Model
In House Coverage
Enterprises must manage:
Three rotating shifts
Shift handover gaps
Weekend and holiday monitoring
On-call escalation
Fatigue-driven error risks
Even small staffing gaps create blind windows.
Outsourced Coverage
Managed SOCs operate:
Continuous follow-the-sun coverage
Redundant analyst pools
Automated escalation
SLA-driven incident response
This ensures detection and response continuity at all hours.
Pros and Cons of Each Model
In House SOC Pros
Full data ownership
Deep business context
Custom detection engineering
Dedicated security culture
In House SOC Cons
High recurring cost
Analyst hiring risk
Long maturity timelines
Integration complexity
Operational fragility during attrition
Outsourced SOC Pros
Lower cost at scale
Immediate 24 by 7 coverage
Access to advanced threat hunting
Faster detection engineering maturity
SLA-backed response
Outsourced SOC Cons
Shared platform across customers
Dependency on provider processes
Custom use case development may take longer
Recommendation Matrix: Build or Outsource
Condition | Recommended Model |
|---|---|
Under 3000 employees | Outsource |
Limited SOC hiring capability | Outsource |
Heavy compliance pressure | Outsource or Hybrid |
Mature security team with threat hunters | In house |
Budget constrained enterprise | Outsource |
Complex OT or proprietary environments | Hybrid |
Most Indian enterprises between 500 and 5000 employees achieve better security outcomes with a managed AI SIEM backed SOC.
How AI SIEM Changes the Build vs Outsource Decision
AI SIEM dramatically reduces:
Tier 1 alert volume
Manual triage workload
False positives
Investigation time
However, it does not eliminate:
Detection engineering skills
Threat hunting expertise
24 by 7 operational discipline
This is why many enterprises adopt:
AI SIEM as the core detection engine
Outsourced MDR as the operating layer
This hybrid model delivers speed, scale, and economic efficiency.

When Outsourced 24 by 7 SOC Makes the Most Sense
Outsourced SOC is strongly recommended when:
The enterprise lacks security hiring capacity
Compliance mandates require continuous monitoring
Incident response maturity is low
Alert volume exceeds internal processing capacity
Cloud, identity, and endpoint telemetry complexity is high
In these environments, outsourcing becomes a risk reduction decision, not a cost decision.
Relationship Between 24 by 7 SOC and AI SIEM
AI SIEM provides:
Unified telemetry
Automated correlation
Contextual detection
Predictive risk analytics
24 by 7 SOC provides:
Continuous monitoring
Incident validation
Containment execution
Threat hunting
Forensic investigation
Together, they form the operational backbone of modern enterprise cyber defense.
If your organisation is debating whether to build a full time SOC or move to a managed detection model, a 24 by 7 SOC readiness assessment will reveal the exact cost, coverage gaps, and operational risks in your current approach.
This assessment converts your detection maturity, staffing exposure, and automation capability into a clear build versus outsource decision framework.
FAQs
1) Is it cheaper to outsource a 24 by 7 SOC in India
Yes. For most mid to large enterprises, outsourced SOC services cost 40 to 60 percent less than running a fully staffed in house 24 by 7 SOC.
2) Does outsourced SOC reduce visibility into security operations
No. Modern managed SOC platforms provide real time dashboards, incident reports, compliance metrics, and full investigation transparency.
3) Can AI SIEM work without an in house SOC
Yes. AI SIEM can be fully operated by an MDR provider while the enterprise retains control over data, policies, and response approvals.
4) What is the ideal SOC model for a 1000 employee enterprise
For most 1000 employee organisations, an outsourced 24 by 7 SOC powered by AI SIEM provides the best balance of security coverage, cost efficiency, and operational maturity.
