A managed Security Operations Centre (SOC) gives small businesses enterprise-grade 24/7 threat monitoring without hiring a full security team. Here's how it works, what it costs, and whether you need one.
A Security Operations Centre (SOC) was once exclusively for enterprises with $10M+ security budgets and teams of 20+ analysts. In 2026, managed SOC services have democratised this capability — small businesses with 10 employees can now access the same 24/7 threat detection and response that Fortune 500 companies rely on, at a fraction of the cost.
But there's significant confusion in the market about what a managed SOC actually does, what it costs, and whether a small business genuinely needs one. This guide answers all of it.
What Is a SOC?
A Security Operations Centre is a centralised team and technology platform that continuously monitors an organisation's IT environment for threats. A SOC combines:
- People — Security analysts working in shifts to provide 24/7/365 coverage
- Process — Defined playbooks for detecting, investigating, and responding to incidents
- Technology — SIEM (Security Information and Event Management), SOAR (Security Orchestration, Automation and Response), threat intelligence feeds, EDR platforms
What Is a Managed SOC?
A managed SOC (also called SOC-as-a-Service or MSSoC) delivers all of the above as an outsourced service. Instead of building your own SOC — which requires hiring 6–10 security analysts, deploying enterprise SIEM software, and maintaining 24/7 shift coverage — you subscribe to a managed SOC provider who monitors your environment from their own operations centre.
Your managed SOC provider watches your:
- Endpoints (laptops, servers, mobile devices)
- Network traffic (firewalls, switches, DNS logs)
- Cloud infrastructure (AWS, Azure, GCP)
- SaaS applications (Microsoft 365, Google Workspace, Salesforce)
- Identity systems (Active Directory, Okta)
- Email (phishing, BEC, data exfiltration)
What Does a Managed SOC Actually Do Day-to-Day?
Detection
The SOC ingests billions of log events from across your environment and uses a combination of signature-based rules, behavioural analytics, and AI/ML models to identify anomalies. A managed SOC correlates events that look innocent in isolation — a failed login, followed by a successful login from a different country 20 minutes later, followed by a large file download — into a meaningful alert.
Investigation
When an alert fires, SOC analysts investigate: Is this a real threat or a false positive? They pull context from threat intelligence feeds, look at the user's historical behaviour, check whether the activity matches known attack patterns, and make a determination.
Response
For confirmed threats, the SOC takes action — either automated (isolating a compromised endpoint, blocking a malicious IP, disabling a compromised account) or by alerting your team and walking you through remediation steps.
Reporting
Monthly reports covering threats detected, false positives, response times, and trending attack patterns help you understand your security posture over time.
In-House SOC vs. Managed SOC: Cost Comparison
| Item | In-House SOC | Managed SOC |
|---|---|---|
| Security analysts (3 for 24/7 coverage) | $285,000–$360,000/year | Included |
| SIEM software (Splunk/Microsoft Sentinel) | $50,000–$200,000/year | Included |
| Threat intelligence feeds | $20,000–$60,000/year | Included |
| EDR platform | $15,000–$40,000/year | Often included |
| Training & certifications | $15,000–$30,000/year | Included |
| Total annual cost | $385,000–$690,000 | $24,000–$96,000 |
For a 25-person company, a managed SOC costs $2,000–$8,000/month — providing capabilities that would cost $32,000–$58,000/month to replicate in-house.
Do Small Businesses Actually Need a Managed SOC?
Not every small business does. Here's how to assess your need:
You likely need a managed SOC if:- You handle sensitive customer data (healthcare, financial, legal, HR)
- You have compliance requirements (HIPAA, PCI-DSS, SOC2, ISO 27001)
- You've experienced a security incident in the past 2 years
- You have remote workers accessing company systems
- A breach would cause irreparable reputational or financial damage
- Enterprise customers require evidence of security monitoring
- You handle no sensitive customer data
- Your entire team is on-site with managed devices
- You have fewer than 5 employees with very limited IT infrastructure
What to Look for in a Managed SOC Provider
- True 24/7/365 coverage — not "follow-the-sun" with coverage gaps
- Mean Time to Detect (MTTD) under 1 hour — industry benchmark for 2026
- Mean Time to Respond (MTTR) under 4 hours for critical incidents
- Dedicated analyst assigned to your account — not a shared pool that doesn't know your environment
- Transparent SLA in writing — response time guarantees should be contractual
- Integration with your existing tools — EDR, SIEM, cloud platforms
- Threat hunting capabilities — proactive search for threats, not just reactive alerting
How Long Does Managed SOC Onboarding Take?
A typical managed SOC onboarding takes 2–4 weeks:
- Week 1: Asset discovery, log source integration, baseline baselining
- Week 2: Detection rule tuning, custom playbook creation for your environment
- Week 3–4: False positive reduction, analyst familiarisation with your environment
- Week 4+: Full 24/7 monitoring active
Our Managed SOC service provides 24/7/365 monitoring with a dedicated analyst team, sub-1-hour MTTD SLA, and full integration with your existing Microsoft 365, Google Workspace, and cloud infrastructure. Most clients are fully onboarded within 10 business days. Request a free security assessment — we'll show you exactly what threats exist in your environment right now.
