SOC Outsourcing | 24/7 Security Monitoring

Last updated: November 11, 2026

SOC outsourcing gives you a security operations centre that watches your logs and endpoints around the clock, triages alerts, investigates suspicious activity and guides containment when an incident happens. Instead of hiring and retaining a full team of analysts, you get trained L1–L3 analysts working on your SIEM, EDR and cloud security tools, with clear SLAs and reporting. For availability and performance monitoring, see NOC network monitoring outsourcing.

Who is it for and what problem does it solve

Most mid-sized companies already own security tools: a firewall, endpoint protection, Microsoft 365 or Google Workspace security features, perhaps a SIEM. The pain is that alerts arrive faster than anyone can read them. A phishing click on Friday evening or a suspicious admin login on Sunday morning is often discovered on Monday, or never. Hiring a 24/7 security team is expensive and analysts with SOC experience are hard to retain.

SOC outsourcing suits companies that need continuous monitoring to satisfy customers, auditors or insurers; organisations in finance, healthcare, e-commerce, SaaS and manufacturing; and internal security teams that want to keep engineering and architecture work in-house while handing over shift-based monitoring.

SOC technology stack: SIEM, SOAR, EDR and more

Component	Purpose	Common products
SIEM	Collect, correlate and search logs from all sources	Microsoft Sentinel, Splunk, Elastic Security, IBM QRadar, Wazuh
EDR / XDR	Detect and respond on endpoints and servers	Microsoft Defender for Endpoint, CrowdStrike Falcon, SentinelOne, Trend Micro
SOAR	Automate enrichment and response playbooks	Sentinel playbooks, Splunk SOAR, Cortex XSOAR, Shuffle
Identity security	Detect risky sign-ins and privilege abuse	Entra ID Protection, Okta, Active Directory monitoring
Cloud security	Monitor cloud control planes and workloads	AWS GuardDuty, Defender for Cloud, Google Security Command Center
Threat intelligence	Enrich indicators and track campaigns	Commercial and open feeds, MISP

We work on the platform you already own whenever possible. If you have no SIEM, we help you choose and deploy one that fits your budget and log volume.

Detection coverage with MITRE ATT&CK

We map detection rules to MITRE ATT&CK techniques so that you can see which attacker behaviours are covered and where the gaps are. Coverage is reviewed regularly: new rules are added for relevant threats, noisy rules are tuned, and detections are tested with safe simulations. This turns “we have a SIEM” into a measurable picture of what would actually be detected.

Service scope and roles

L1 analyst: monitors the alert queue, performs initial triage and enrichment, closes false positives with documented reasoning, escalates real events.
L2 analyst: investigates escalated alerts, correlates data across sources, determines scope and recommends or performs agreed containment.
L3 / incident responder: handles complex incidents, threat hunting and root cause analysis.
Detection engineer: writes and tunes rules, builds playbooks, onboards log sources.
SOC lead: owns SLAs, reporting and communication with your team.

Regulations and standards

Our processes support ISO/IEC 27001 controls, NIST CSF and incident handling practices based on NIST SP 800-61. In Turkey, where the team operates, KVKK breach notification rules, the Presidential Digital Transformation Office Information and Communication Security Guide, and sector rules from BDDK and SPK are relevant. Local rules in your country apply as well, for example GDPR breach notification, NIS2 and DORA in the EU, or sector requirements in the UK, US and GCC, and we adapt notification and reporting processes to them.

Working models

Model	How it works	Best for
Fully managed SOC	We monitor, triage, investigate and guide response 24/7	Companies without a security team
Co-managed SOC	Your team owns architecture and decisions, we run shifts and triage	Internal teams that need coverage
Out-of-hours SOC	We cover nights, weekends and holidays	Daytime security teams
Dedicated analysts	Named analysts work inside your tools as part of your team	Large or regulated environments

Remote, on-site or hybrid arrangements are possible, with teams from a single analyst up to full 24/7 shifts.

Onboarding process

Assessment: current tools, log sources, critical assets and existing incident procedures.
Log source onboarding: prioritised by risk, starting with identity, endpoints, firewalls and cloud control planes.
Use cases and playbooks: agreed detection use cases, escalation matrix and response permissions.
Baseline and tuning: a tuning period to reduce false positives before full SLAs apply.
Steady state: 24/7 monitoring, monthly reports and quarterly coverage reviews.

A team can typically start in 1–2 weeks; full log source coverage depends on the size of your environment.

The lifecycle of an alert

Alert is generated by SIEM or EDR and enriched automatically.
L1 analyst triages it: false positive, benign true positive or suspicious.
Suspicious alerts are escalated to L2 with collected evidence.
L2 determines scope and impact, and contains (for example isolating a host or disabling an account) within agreed permissions.
Your team is informed according to priority; incidents get a written timeline and recommendations.
Lessons learned feed back into detection rules and playbooks.

SLA and KPI table

KPI	What it measures
MTTA (mean time to acknowledge)	Time from alert to analyst pickup
MTTD / MTTR	Time to detect and to contain or resolve incidents
Escalation accuracy	Share of escalations that were justified
False positive rate	Alerts closed as false positive, used for tuning
Log source health	Sources sending data as expected
ATT&CK coverage	Techniques with tested detections

Targets are set per priority in the service agreement, based on your risk profile; we do not promise generic figures.

SOC and Security Monitoring Outsourcing — overview

Pricing factors

Factor	Effect on cost
Coverage hours	Business hours, out-of-hours or 24/7
Log volume and number of sources	Affects triage workload and SIEM effort
Number of endpoints and users	Drives EDR alert volume
Response scope	Monitoring and notification only, or active containment and incident response
Platform ownership	Your SIEM licence or one we operate
Reporting and compliance needs	Custom reports, audit support, language requirements

In-house SOC, freelancer or outsourcing

Criterion	In-house SOC	Freelancer	Outsourced SOC
24/7 coverage	Requires a large team	Not realistic	Included
Time to start	Many months	Fast but limited	Typically 1–2 weeks
Continuity	Depends on retention	Single point of failure	Replacement process
Process maturity	Must be built	Varies	Playbooks and reporting included

Risks and mitigations

Alert fatigue: structured tuning and monthly false positive reviews.
Privileged access by a third party: least privilege, MFA, PAM, full audit logging.
Unclear response authority: written response matrix agreed before go-live.
Blind spots: log source health monitoring and ATT&CK coverage reviews.

Security, data protection, NDA and intellectual property

Security logs often contain personal data such as user names, IP addresses and e-mail metadata. We process it only for the agreed purposes, keep it in your environment where possible and follow your retention rules.

Contract framework: we work under a B2B service agreement with a clear statement of work. An NDA is signed before any access is granted, and all deliverables, detection rules, playbooks, reports and documentation created for you are assigned to you as intellectual property. Where we process personal data on your behalf, we sign a GDPR-compliant data processing agreement (DPA) with Standard Contractual Clauses (for UK clients, the IDTA or UK Addendum); on the Turkish side the team also complies with KVKK (Law No. 6698). Team members are employed by 360 Soft under Turkish labour law, so there is no employment relationship between them and your company.

Illustrative scenario

Illustrative scenario: a SaaS company with a small internal security team uses Microsoft Sentinel and Defender but only reviews alerts during office hours. A co-managed SOC takes over nights and weekends; when an impossible-travel sign-in followed by mailbox rule creation is detected on a Saturday, the analyst disables the session within agreed permissions and hands over a timeline to the internal team on Monday. This example is for illustration only.

Frequently asked questions

What is the difference between SOC and NOC?

A SOC monitors security events and threats; a NOC monitors availability and performance. Many companies run both with a shared escalation path.

Do we need our own SIEM?

Not necessarily. We can work on your existing SIEM or help you select and deploy one that fits your log volume and budget.

Which tools do you support?

Microsoft Sentinel, Splunk, Elastic, QRadar, Wazuh, Defender, CrowdStrike, SentinelOne and other common SIEM, EDR and cloud security platforms.

Will you take action on our systems?

Only within a response matrix you approve, for example isolating a host or disabling an account. Everything else is a recommendation to your team.

Do you provide 24/7 coverage?

Yes. We offer business hours, out-of-hours and full 24/7 shift models.

Do you do incident response?

L2 and L3 analysts investigate and guide containment. For large incidents we coordinate with your team, legal advisers and any external forensic partner.

Do you do threat hunting?

Yes, proactive hunting based on threat intelligence and ATT&CK techniques can be part of the scope.

How do you handle personal data in logs?

Under a DPA, with access limited to the agreed purpose, data kept in your environment where possible and your retention rules applied.

How quickly can you start?

Typically within 1–2 weeks; full coverage depends on log source onboarding.

Who owns the detection rules and playbooks?

You do. Everything created for you is assigned to you under the contract.
