Solving the SOC Data Dilemma: Maximising Detection Without Maximising Cost

Today's Security Operations Centres (SOCs) operate under the pressure of data proliferation, high alert volumes, and tight budgets. Most SOC leaders face a data dilemma: they must choose which data to analyse and which to ignore. That choice directly determines threat detection capabilities and impacts the security posture of the business.
This reality creates a critical gap. If visibility is limited by cost or platform constraints, detection capability is inherently compromised. The challenge for CISOs and SOC leaders is therefore clear: how can they maximise detection coverage without unsustainable increases in cost or operational complexity?
The answer lies in rethinking data ingestion by converting it from a volume problem to an optimisation challenge.
How SOCs Are Charged for Data Ingestion and Why It Breaks at Scale
Traditional SIEM pricing models are often based on log ingestion volume. While simple in concept, this model creates two major issues. First, costs are unpredictable. Log volumes fluctuate, making budgeting difficult. Second, teams may be forced to limit ingestion to control costs, reducing visibility. In tandem, these issues frustrate SOC leaders, forcing them into an uncomfortable trade-off: either ingest everything and overspend, or ingest selectively and accept blind spots.
At scale, this model grows unsustainable. Organisations are dealing with exponential data growth from endpoints, cloud platforms, SaaS applications, and identity systems. Simply ingesting "everything into analytics" is no longer efficient. Nor is it necessary.
Not All Data Is Equal: A Tiered Approach to Data Value
A key shift in modern SOC architecture is the recognition that not all data needs to be treated the same way.
From an operational perspective, data typically falls into three categories:
1. Data for Active Detection and Defence
This is the most critical data, comprising the logs and telemetry that drive real-time analytics and threat detection. It must be processed and acted on immediately, which is often a resource-intensive activity.
2. Data for Investigation and Post‑Incident Analysis
This data is not required for real-time detection but is essential for threat hunting, forensic investigations, and alert enrichment.
3. Data for Compliance and Retention
Certain logs must be stored for regulatory or audit purposes but are rarely used operationally. These datasets often constitute a large proportion of ingested data but deliver minimal detection value. Organisations frequently ingest data that they know will not be used for detection but must be stored for regulatory reasons, something that adds to operational cost.
Treating all three categories equally by sending everything into high-cost, real-time analytics pipelines, is inefficient and drives unnecessary expenditure.
Intelligent Data Routing through Data Pipeline Management
By taking a granular, use case-defined approach to data ingestion management, organisations can enhance detection coverage without elevating costs or compromising on compliance or research requirements.
Rather than treating all logs the same, solutions like Securonix Data Pipeline Manager dynamically route data into three distinct tiers:
- Analytics tier: High-cost, real-time detection data
- Investigation tier: Mid-cost data for search and enrichment
- Basic tier: Low-cost storage for compliance
This architecture enables organisations to ingest all relevant data without paying the same price for every byte.
Importantly, this is not a static approach. SOC teams can define routing rules at granular levels, even within a single data source. For example, the solution can be tuned so only specific high-value events are sent to analytics and the rest – that which corresponds to investigation or basic compliance use cases – is stored or made available for later research and investigation.
This flexibility ensures that data is used "in the right way and in the right place," optimising both performance and cost.
Depending on the data mix and existing ingestion practices, deploying this model for intelligent data ingestion can typically reduce SIEM costs by 30-50%, while actually increasing overall data coverage, thereby solving the SOC leader's data dilemma. It also means analysts spend less time dealing with noise caused by data that – while relevant to the bigger picture – is not what they need for the front-line elements of their role.
AI‑Powered SOCs: Turning Data into Actionable Intelligence
Optimised data ingestion becomes even more powerful when combined with AI agents to enhance detection and response. In modern AI-powered SOC architectures, these capabilities can be orchestrated through an agentic framework, such as the Securonix Agentic Mesh, where specialised AI agents collaborate across detection, investigation, enrichment and response workflows to accelerate security outcomes while maintaining analyst oversight. Such agents operate at multiple levels:
1. Detection Enhancement
AI-powered behavioural analytics (UEBA) identifies anomalies that traditional rule-based systems cannot detect. By learning "normal" behaviour and flagging deviations, such as unusual access patterns or atypical data volumes, the system can detect low-and-slow attacks and insider threats that often evade static rules.
2. Alert Correlation and Contextualisation
Agents can also be leveraged to correlate multiple events into unified incidents, allowing analysts to view threats holistically instead of as isolated alerts. This ultimately generates fewer alerts and allows analysts to make faster decisions based on better information.
3. Analyst Productivity and Automation
AI agents assist analyst productivity by undertaking actions such as generating incident summaries, creating activity timelines and suggesting remediation actions. This effective pre-processing of analysis work reduces the time needed to understand and respond to incidents. The addition of natural language querying also lowers the barrier to entry for junior analysts, enabling them to upskill and develop competencies more quickly.
4. Continuous Optimisation
AI in the SOC also helps tune detection rules, reduce false positives, and refine data usage over time, creating a feedback and learning loop that improves efficiency and accuracy.
The Role of Context in Accelerating Investigations
One of the most significant productivity gains comes from data enrichment. When this happens at the point of ingestion, linking events to the relevant users, devices, locations and roles, the impact is multiplied. Analysts can immediately understand the "who, what, and where" of an incident.
Without this context, analysts spend a large portion of their time searching across tools. With enriched data, this time is dramatically reduced. Analysts spend less time on data-gathering, and more time actually analysing and responding.
A New Intelligent Data-Driven Model for the AI‑Powered SOC
The modern SOC must balance three competing priorities: visibility, cost control, and operational efficiency. Conventional SIEM models struggle to scale to match the pace of AI-powered threats because they force a compromise between these objectives.
By laying strong foundations with intelligent, tiered data ingestion and storage, then layering on UEBA-driven incident detection, AI-powered automation and agent deployment, SOC leaders can align data value with cost and leverage AI to amplify human expertise.
Ultimately, optimising data ingestion is not just about cost savings. The organisations that succeed will not be those that collect the most data, but those that extract the most value from it.
