Hypothesis
Define behavior and evidence.
Turn alerts into response decisions
Use the tools you already own to recognize suspicious behavior, reduce noise and guide the next action.
Client situation
A rule is not a detection capability until it is observable, tested and operable.
Sources arrive incomplete, rules are inherited without hypotheses and alerts do not indicate the next decision. Tools exist; real coverage remains unknown.
What Bellot reviews
We look at the real environment, not a generic checklist.
- Sources, fields, retention and quality
- Use cases and behavioral coverage
- Triage, investigation and escalation
- SIEM, EDR, IAM, cloud and network integration
What you receive
Clear outputs your team can use.
- Coverage and gap matrix
- Documented detection package
- Test scenarios and results
- Runbooks and evolution backlog
How the engagement works
A controlled path from context to operational capability.
Instrument
Ensure source, field and context.
Detect
Build, test and tune.
Operate
Integrate triage and lifecycle.
Engagement modes
Assessment, engineering or continuous evolution, each with a different commitment.
Assessment
Diagnosis, evidence and prioritized plan.
Engineering project
Implementation, validation and technical transfer.
Continuous evolution
Review, tuning and improvement in defined cycles.
Harpia / Operational role
AI expands analysis. Authority stays explicit.
With authorized telemetry, Harpia normalizes entities, relates signals and surfaces context; impactful responses remain human-governed.
What we need from the client
- Controlled platform access
- Event samples and documentation
- Response workflow owners
Boundaries and exclusions
- Does not replace a 24x7 SOC
- Coverage depends on available telemetry
- Automatic blocking requires specific approval
Complementary modules
- SIEM architecture
- Automation
- Threat-informed detection
- Training
When to engage
Bring Bellot in when the next defensive decision requires evidence.
Noisy SIEM or EDR
Operations without a coverage view
Maturing internal monitoring
Scope, access and operating boundaries are confirmed before work begins.
