CyberSilo SOC as a Service: How Our European SOC Operates 24/7

What Is SOC as a Service and Why It Matters for European Businesses

SOC as a Service (often called a managed SOC or SOC-as-a-Service) is a subscription-based security operations model where a third-party provider delivers 24/7 monitoring, log analysis, and incident response from a dedicated security operations centre. Unlike traditional in-house SOCs, which require significant investment in staff recruitment, retention, and technology stack management, a service model shifts the operational burden to a specialised provider.

European regulated entities face particular challenges that make SOC as a Service attractive:

• NIS2 compliance: Article 21 requires essential and important entities to implement proportionate technical and organisational measures for incident detection and response. A 24/7 SOC provides the continuous monitoring and response capability that many organisations cannot staff internally.
• GDPR data protection obligations: Article 32 mandates appropriate technical measures to ensure ongoing confidentiality, integrity, availability, and resilience of processing systems. Real-time monitoring directly supports this requirement.
• DORA for financial entities: The Digital Operational Resilience Act requires ICT risk management frameworks that include threat detection and incident response. A managed SOC provides demonstrable evidence of compliance.
• Skills shortage mitigation: With over 883,000 cybersecurity professionals needed in Europe (ISC² 2024 study), outsourcing SOC operations alleviates the recruitment challenge.

How CyberSilo’s European SOC Operates 24/7

CyberSilo operates multiple SOC nodes across Europe, ensuring compliance with data sovereignty requirements while delivering round-the-clock coverage. Our operational model is built around three core layers: detection, analysis, and response.

Tier 1: Monitoring and Alert Triage

A dedicated team of shift-based analysts continuously monitors telemetry from SIEM, EDR, network detection, cloud security, and identity platforms. Alerts are triaged in real time against the organisation’s baseline behaviour profiles. For European clients, this includes monitoring for indicators of compromise (IoCs) specific to regional threat actors, such as ransomware groups targeting EU critical infrastructure.

Tier 2: Investigation and Threat Confirmation

When Tier 1 surfaces a potential incident, Level 2 analysts conduct deeper investigation using endpoint forensics, log correlation, and threat intelligence feeds. CyberSilo’s European SOC integrates with ThreatSearch TIP to enrich alerts with contextual data from multiple sources, including ENISA cyber threat information sharing and national CERT feeds across EU member states.

Tier 3: Incident Response and Remediation

For confirmed incidents, Level 3 analysts execute predefined playbooks tailored to the client’s environment and regulatory obligations. Response actions include host isolation, credential revocation, network segmentation, and evidence preservation for regulatory reporting under NIS2 or GDPR. The SOC also coordinates with the client’s in-house incident response team and legal counsel where required.

Key Capabilities of a European Managed SOC

A mature SOC as a Service for European organisations goes beyond basic log monitoring. The following capabilities directly address the security and compliance needs of regulated entities:

SOC Model Comparison: In-House vs Managed vs Co-Managed

European organisations evaluating SOC options typically consider three models. The choice depends on organisational maturity, budget, compliance obligations, and risk appetite.

The SOC as a Service model is particularly suited to European organisations that must demonstrate compliance with NIS2 or DORA within constrained budgets and tight timelines. It also suits organisations operating across multiple EU jurisdictions, where maintaining separate in-house SOCs in each country is impractical. For organisations with existing SOC maturity, the co-managed MDR model allows internal teams to retain control over Tier 3 response while outsourcing Tier 1 and Tier 2 workload.

The Role of a SOC in NIS2 and DORA Compliance

European regulations increasingly mandate continuous monitoring and incident response capabilities. A SOC as a Service directly supports compliance with several regulatory requirements:

• NIS2 Article 21 (Cybersecurity risk-management measures): Requires essential and important entities to implement policies on “cyber hygiene practices and cybersecurity training”, “incident detection”, and “business continuity management”. 24/7 SOC monitoring satisfies the detection obligation and generates audit evidence.
• NIS2 Article 23 (Reporting obligations): Mandates early warning notifications within 24 hours of becoming aware of a significant incident, followed by an incident notification within 72 hours and a final report within one month. A SOC accelerates detection, triage, and reporting preparation.
• DORA Article 11 (ICT risk management framework): Requires financial entities to implement “processes for the detection of anomalous activities” and “ICT incident response processes”. The SOC provides these processes as a managed service with documented SLAs.
• DORA Articles 17–18 (ICT incident reporting): Establishes a standardised incident reporting framework. SOCs capture the structured data elements required for DORA-compliant incident reports.

CyberSilo’s SOC services include compliance-aligned reporting as standard. Incident reports are formatted to meet NIS2 and DORA notification requirements, and audit logs are retained in accordance with GDPR Article 5(1)(e) storage limitation requirements.

SOC Pricing Models: What European Organisations Should Expect

SOC as a Service pricing for European organisations typically follows one of three models. Understanding these options helps buyers make cost-effective decisions aligned with their compliance obligations:

Tiered Pricing (Per Asset or User)

The most common model for small to mid-size organisations. Pricing is based on the number of monitored endpoints (servers, workstations, cloud instances) or active users. Typical European market rates for a full 24/7 SOC service range from €8 to €20 per asset per month, depending on the depth of monitoring (SIEM only vs SIEM + EDR + network).

Flat-Rate Monthly Retainer

Suitable for organisations with stable and predictable IT footprints. A fixed monthly fee covers the full monitoring scope, including a defined number of incident response hours. Typical flat-rate pricing for organisations with 500–2,000 assets ranges from €8,000 to €18,000 per month across European providers.

Consumption-Based Pricing

Less common but available for cloud-native organisations. Pricing scales with log volume, cloud workload count, or API call volume. This model offers flexibility for highly dynamic environments but requires careful forecasting to avoid budget variance.

Data Sovereignty and SOC Location in Europe

For European organisations, the physical location of SOC operations and data processing carries legal significance under GDPR Chapter V (international transfers) and national data protection laws. CyberSilo operates SOC nodes within the EU and UK, ensuring that:

• Client telemetry and logs are processed and stored within the European Economic Area or the UK.
• Transfer mechanisms (adequacy decisions, SCCs, or derogations) are documented where data crosses borders between EU nodes.
• Incident data that may constitute a personal data breach under GDPR Article 33 is handled by analysts trained on breach notification requirements across multiple EU member states.

For organisations in sectors such as critical infrastructure, healthcare, or public administration, the ability to specify data residency requirements in the SOC contract is essential. CyberSilo enables clients to define which SOC node processes their data, with contractual commitments on data location.

How to Choose a SOC as a Service Provider in Europe

Selecting a SOC provider for a European regulated organisation requires careful evaluation beyond basic feature comparison:

• Regulatory alignment: Does the provider demonstrate operational knowledge of NIS2, DORA, GDPR, and national transpositions? Are their analysts trained on these frameworks?
• Data governance: Can the provider guarantee data processing within the EU/EEA or UK? Do they have documented data processing agreements compliant with GDPR Article 28?
• Integration capability: Does the SOC integrate with your existing security stack (SIEM, EDR, NDR, IAM)? CyberSilo’s SOC is compatible with major platforms, including ThreatHawk SIEM and leading third-party tools.
• Incident response maturity: What SLAs apply for detection, triage, and escalation? Does the provider have experience with NIS2 incident reporting timelines?
• Certifications: Look for ISO 27001 certified SOCs with staff holding GIAC, CISSP, or equivalent qualifications. CyberSilo holds ISO 27001:2022 certification across its SOC operations.
• Language and time zone coverage: For organisations operating across multiple EU member states, multi-language support and local time zone coverage are valuable differentiators.
