Incident Triage

Validin supports incident triage by providing an historical, infrastructure-level evidence layer to teams reacting to security incidents.

Validin is used to validate, contextualize, and scope indicators produced by security systems and investigations, facilitating long-term visibility into how infrastructure behaves, changes, and relates to other assets over time.

How Validin's data supports triage decisions

During triage, teams are typically required to justify why an alert is escalated, monitored, or closed. Validin provides the underlying data used to support those decisions.

Validin answers common triage questions across DNS, host response, certificates, registration records, and OSINT context.

Infrastructure age and history

During the triage process, teams need to know how long infrastructure has existed and how stable it has been.

Validin’s historical datasets allow teams to determine whether an indicator is newly created, long-lived, or intermittently active. DNS history, certificate issuance timelines, and registration records are commonly reviewed together to establish baseline behaviour.

This helps teams distinguish between transient infrastructure and assets with long operational history.

Change and coordination signals

Beyond age, Validin data highlights when and how infrastructure changes.

DNS updates, certificate replacements, hosting shifts, and registration changes are preserved historically. When multiple changes occur within a short time window, this can indicate coordinated activity rather than routine maintenance.

These signals are used during triage to assess whether alerts represent isolated events or part of a broader change pattern.

Behavioural context from host responses

Host response data provides direct evidence of how services behave when accessed.

Response headers, page content, redirects, favicons, and TLS characteristics are used to confirm whether infrastructure is behaving as expected.

Teams use Validin to look for repeated or identical response artefacts across multiple hosts to locate shared tooling or reused configurations.

Relationship and scope awareness

Triage often requires an understanding of whether an indicator stands alone or is connected to other assets.

Validin enables teams to identify relationships through shared DNS resolution, certificates, registration attributes, or response characteristics. This allows teams to quickly assess scope, without expanding into a large-scale investigation.

Explainable threat context

Validin integrates selected open source intelligence sources into the platform, to provide documented context where available.

Threat profiles, general reference data, and external reports are provided alongside first-party data, allowing teams to confirm whether infrastructure has been previously associated with known activity.

Note

OSINT context supplements triage decisions but does not replace observed infrastructure behaviour.

Use of Projects during triage

When indicators require tracking beyond initial triage, teams can record them in Projects.

Projects provide a place to preserve triage context, record rationale, and observe changes over time. This supports handoffs, reviews, and follow-on investigation if activity evolves.

Automation and policy alignment

Validin’s API allows teams to integrate infrastructure context directly into triage pipelines.

Historical age, stability, or known associations can be used as inputs for blocking rules, prioritization, or analyst assignments.
