Sufficient evidence
Signals and context are correlated until a verifiable basis exists to begin the decision process.
Decision Architecture
A new computational layer between threat detection and defensive action, designed to transform evidence into governed, authorized, and auditable decisions.
The decision link between detection and action
Sensores, SIEM, EDR, WAF e outras ferramentas observam e detectam. Firewalls, sistemas de identidade, endpoints and SOAR mechanisms can execute responses. SΛDB occupies the space between those two functions: it determines what to do and under which evidence, policies, limits, and authorizations.
Explicit decision
A structured recommendation is formed separately from authorization and operational execution.
Governed authorization
Institutional policy, identity, scope, and limits are applied before any action is released.
Decision traceability
A verifiable link connects evidence, decision, authorization, execution attempt, and observed outcome.
Controles arquiteturais fundamentais
Operational speed is useful only when it remains subordinate to decision integrity and organization-defined limits.
Fail closed
Invalid evidence, authorization, or integrity prevents progression to execution.
Evidence binding
Authorization remains bound to the context and evidence set that supported the decision.
Durable authorization
A recommendation does not become executable without unambiguous, durable authorization.
Verifiable trail
Relevant transitions preserve identity, time, policy, and outcome for audit.
Como o SΛDB complementa a infraestrutura existente
SΛDB is not intended to replace the security ecosystem. It creates a governed decision boundary between observation and action.
Existing tools
Each component continues to perform the function it was designed for within the security environment.
- Sensors and EDR produce telemetry and detections.
- SIEM aggregates, correlates, and presents alerts.
- WAF, firewall, and IAM apply controls.
- SOAR integrates tools and automates playbooks.
Decision Architecture
SΛDB adds the decision, governance, and authorization logic required before action.
- Determines when sufficient evidence exists.
- Forms an explainable defensive recommendation.
- Applies policy and explicit authorization.
- Releases only governed and auditable actions.
Conceptual decision flow
A clear representation of how evidence, decision, policy, authorization, and execution relate.
Evidence received
Defensive signals are received, normalized, and bound to the operational context.
- Event origin and identity recorded.
- Evidence integrity preserved.

Formal flow: signals form context, support a decision, cross the authorization boundary, and only then can reach execution.
