Data Normalization

Turn Raw Logs Into Investigation-Ready Data

Beacon eliminates the manual effort of normalizing raw logs, replacing custom parsers and scripts with expert-validated mappings that make investigations faster and detections consistent across every source

Data You Can Actually Work With

Faster investigations

Analysts and agents work with consistent, structured fields across every source, allowing for more efficient investigations.

Stronger detections

Data is normalized with security logic in mind. Fields are mapped, correlated, and structured to match how detection rules and analysts actually think.

No engineering maintenance

Onboard new sources or maintain existing ones without parser rewrite, engineering cycles or growing maintenance backlogs.

Show me how

Beacon's security-driven data platform optimizes terabytes of important security logs spanning many sources. Data arrives enriched and normalized, and in the case of bloated VPC flow logs, reduced to 5% of their original size, enabling our security team and AI workflows to act immediately and effectively. We no longer choose between coverage and cost efficiency. We now have both, supported by a responsive team of security data experts.

Frequently Asked Questions

What is schema normalization in security logging?

Schema normalization is the process of transforming raw, source-specific logs into a consistent structure (such as ECS, OCSF, ASIM, or a custom schema) so detections, queries, and investigations work reliably across all data sources. It ensures that tools receive data in the exact format they expect.

Why is normalization important for existing SIEMs?

Most SIEM content (detections, correlations, dashboards) assumes logs follow a specific schema. When new or unsupported sources don’t match that structure, rules fail silently or require custom rewrites. Beacon ensures incoming telemetry is mapped to the schemas your SIEM expects, so detection logic works consistently without constant maintenance.

Does normalization affect detection fidelity?

No. Beacon preserves all fields required for detections and investigations while aligning them to the correct schema. Normalization improves reliability by ensuring rules, correlations, and queries run as designed, even when log formats change.

What schemas and formats does Beacon support?

Beacon supports industry-standard schemas such as ECS, OCSF, and ASIM, as well as SIEM-specific native schemas and fully custom formats. Teams can standardize data once and deliver it in the structure each tool expects, without rebuilding pipelines.

Do I need to rewrite parsers when a log format changes?

No. Beacon adapts to schema changes upstream, preserving the structure your SIEM and detection logic expect.

Does normalization add latency to ingestion?

No. Beacon performs normalization in-stream as part of its unified data pipeline. Structured, schema-aligned data arrives ready for detection without slowing ingestion or requiring post-processing

Can normalization help onboard unsupported or niche log sources?

Absolutely. Many SIEMs lack native support for long-tail SaaS, cloud, or internal systems. Beacon maps unsupported sources into your existing schema, allowing you to apply existing detection content without building custom parsers.

Do I need separate parsers for every log source?

No. Beacon normalizes diverse log formats into a consistent schema upstream, eliminating the need to manage and maintain source-specific parsers inside your SIEM.
