Why insurers need a dedicated SOC
Standard SOC solutions do not account for insurance sector specifics. An insurance company processes data of exceptional sensitivity — medical, financial, personal — in systems with complex architecture spanning core insurance, claims management, underwriting, and broker integrations.
A dedicated insurance SOC must understand the business context of operations. An alert about mass data downloads from a claims management system carries an entirely different meaning than a similar alert from a CRM system. A claims adjuster working on a large claim generates access patterns similar to an attacker performing data exfiltration — the SOC must distinguish between these scenarios.
DORA and NIS2 regulatory requirements raise the bar further. The SOC must not only detect threats but also classify incidents according to reporting requirements and generate documentation needed for regulatory notifications.
SOC architecture for the insurance sector
An insurance SOC should be built around a SIEM (Security Information and Event Management) platform integrating logs from all critical systems. Key data sources include: core insurance systems, claims management platforms, customer and agent portals, underwriting systems, network infrastructure, and endpoints.
The SOAR (Security Orchestration, Automation and Response) layer automates standard response procedures — from isolating suspicious endpoints to escalating incidents to appropriate teams. For the insurance sector, SOAR integration with business processes is critical — automatically holding suspicious claims or blocking transactions.
Threat intelligence feeds should be tailored to the financial and insurance sector, providing information about current campaigns targeting the industry, new malware variants aimed at financial systems, and fraud techniques.
Key monitoring use cases in insurance
An insurance SOC must monitor sector-specific threat scenarios. Claims management monitoring includes: detecting unusual claim filing patterns, mass customer data access, post-approval claim modifications, and off-hours system access.
Underwriting system monitoring focuses on: unauthorized changes to pricing parameters, access to actuarial models by unauthorized persons, and risk portfolio data exfiltration. Broker integration monitoring covers: API traffic anomalies, unusual query volumes, and unauthorized access attempts.
An additional layer is anti-fraud monitoring — correlating security alerts with business process anomalies. A medical data breach from a partner system combined with an increase in health claims is a signal requiring immediate escalation.
Operating model — in-house SOC vs outsourcing
Insurers face the choice between building an in-house SOC and outsourcing. An in-house SOC provides full control and deep system understanding but requires significant investment — a team of 9-15 FTE over three shifts for 24/7 coverage (nFlo estimate), SIEM/SOAR infrastructure, and continuous training.
Managed SOC (outsourcing) offers access to an experienced team and advanced tools without capital investment. A hybrid model — an internal Tier 1 team handling business context, supported by an external SOC for Tier 2/3 analysis and off-hours coverage — is often the optimal solution for mid-sized insurers.
nFlo offers a Managed SOC model tailored to the insurance sector. Our analysts understand claims management systems, underwriting processes and broker integrations, so the detection rules cover sector-specific scenarios rather than only the office network. Response times are agreed per incident priority and written into the contract, together with the containment actions the duty team may take on its own.
Step-by-step implementation
Phase 1 — Assessment (2-4 weeks): ICT asset inventory, mapping critical systems and data flows, identifying existing log sources, assessing current security process maturity.
Phase 2 — Design (4-6 weeks): SIEM architecture design, defining insurance-specific correlation rules and use cases, designing escalation processes and business process integrations, planning monitoring coverage.
Phase 3 — Deployment (typically 6-8 weeks): SIEM/SOAR platform deployment, connecting log sources, configuring rules and dashboards, integrating with ticketing systems and incident response processes.
Phase 4 — Tuning (ongoing): adjusting rules based on false positives, expanding use cases, regular threat intelligence reviews and updates, effectiveness exercises and testing.
SOC effectiveness metrics in insurance
Key KPIs for an insurance SOC include: MTTD (Mean Time to Detect) — average threat detection time, targeting under 15 minutes for critical incidents. MTTR (Mean Time to Respond) — average response time, targeting under 30 minutes for high-risk incidents.
Sector-specific metrics: number of detected unauthorized access attempts to claims systems, effectiveness of claims process anomaly detection, time from incident detection to regulator notification (DORA requirement — initial notification within 4 hours of classifying the incident as major, no later than 24 hours after becoming aware of it), critical system monitoring coverage (target: 100%).
Regular board reports should present threat trends, SOC effectiveness, and security improvement recommendations. DORA requires ICT security status reporting to the board — the SOC is the key source of this information.
How nFlo implements SOC for insurers
nFlo specializes in SOC implementation for the financial sector, including insurance. Our approach combines advanced technology with deep understanding of insurance business processes.
We offer the full spectrum of models — from Managed SOC to support in building an in-house SOC. Our correlation rules are developed specifically for insurance systems, and our analysts undergo training in claims management and underwriting processes.
What is worth comparing between monitoring providers in this sector is narrower and checkable: whether the detection use cases cover claims and policy systems rather than only the office network, what the agreed response times are per incident priority in the contract, and which containment actions the duty team may take without waiting for the insurer’s own approval.

Frequently asked questions
Does an insurance company need a SOC?
DORA requires insurers to continuously monitor ICT systems and detect anomalies. A SOC is the standard way to meet this requirement. Without a SOC, an insurer faces regulatory risk and lacks the ability to detect and respond to incidents.
How much does implementing a SOC in an insurance company cost?
The cost depends on the model. An in-house 24/7 SOC requires investment from about €470,000 per year (nFlo estimate; team + infrastructure; converted from PLN at the nFlo reference rate of 4.25 PLN/EUR). A Managed SOC starts in nFlo pricing from about €1,900 net per month, providing immediate access to full monitoring capabilities.
How quickly will the SOC detect an attack on claims systems?
A well-configured SOC with insurance sector-specific rules should detect anomalies in claims management systems within 15 minutes. nFlo sets response times for critical incidents in the contract, per incident priority.
Can a SOC simultaneously monitor security and detect fraud?
Yes, this is one of the key SOC use cases in insurance. Correlating security alerts with business process anomalies enables detecting cyber-enabled fraud — e.g., data breaches leading to fraudulent claims.
