Local-first deployment • Explainable detections • Reduced alert fatigue

Security operations built for organizations without security teams.

W5Σ is a local-first security monitoring appliance designed for small businesses, labs, offices, and practical IT environments. It collects telemetry from your infrastructure, correlates suspicious activity, and presents explainable alerts designed to help identify what actually matters.

Request Demo View Architecture
Local-First
All enrichment, correlation, and detection processing occurs on your infrastructure by default.
Reduced Noise
Routine traffic and known benign activity are filtered from operational triage without deleting underlying evidence.
Explainable Alerts
Detections include severity, confidence scoring, enrichment context, and plain-English explanations.
The W5 Model

Who. What. Where. When. Why.

W5Σ is named after the five investigative questions security operators repeatedly ask during incident triage. The platform was designed to help correlate telemetry into operationally meaningful answers instead of isolated raw alerts.

WHO

Who performed the activity?

W5Σ correlates authentication telemetry, endpoint events, network activity, and enrichment context to help identify which user, host, or account is associated with suspicious behavior.

WHAT

What actually happened?

W5Σ normalizes and correlates telemetry from endpoints, IDS systems, authentication logs, DNS infrastructure, and operating systems to identify suspicious behavior patterns including ransomware activity, malicious infrastructure, exploitation attempts, and privilege escalation.

WHERE

Where did it occur?

W5Σ correlates telemetry across hosts, IDS systems, network infrastructure, authentication systems, and internal addressing to help operators determine where suspicious activity originated or propagated.

WHEN

When did activity occur?

W5Σ preserves timestamped telemetry and searchable retention to support incident reconstruction, operational timelines, historical review, and real-time event visibility.

WHY

Why does the platform believe activity is suspicious?

W5Σ attempts to provide explainable detections using enrichment context, IDS corroboration, incident grouping, suspicious execution telemetry, authentication anomalies, and threat intelligence correlation.
Confidence indicators represent operational correlation confidence derived from available telemetry and enrichment context. Confidence indicators assist triage prioritization and do not represent guarantees of maliciousness or compromise.
What

Correlated detection instead of raw log overload.

W5Σ collects telemetry from endpoints, servers, network devices, authentication systems, IDS platforms, and operating systems to identify suspicious behavior across your environment.

Detection Focus
  • • Ransomware-related activity
  • • Known malicious hashes, domains, and IP addresses
  • • Successful exploitation attempts
  • • Privilege escalation indicators
  • • Suspicious process execution
  • • IDS-confirmed attack activity
  • • Persistence mechanisms and suspicious scheduled tasks
  • • Identity and authentication anomalies
Operational Workflow
  • • Incident grouping and persistent alert state
  • • Confidence percentages and severity scoring
  • • Explainable detections in plain English
  • • Noise filtering without deleting evidence
  • • One-year searchable retention by default
  • • Local-first enrichment and correlation
  • • MITRE ATT&CK and compliance-oriented dashboards
  • • Real-time event stream and triage visibility
Why

Most small organizations do not need more alerts.

They need better visibility, reduced operational noise, and a practical way to understand whether suspicious activity is occurring across their infrastructure.

What W5Σ prioritizes

W5Σ prioritizes evidence of successful compromise, suspicious execution, malicious infrastructure, and ransomware behavior over generic internet background noise.

Routine broadcast traffic, local discovery protocols, and known benign patterns are removed from operational triage views so operators can focus on what actually deserves attention.

All underlying telemetry remains searchable and retained for forensic review.

Why local-first matters

W5Σ is designed around local ownership, deterministic behavior, and infrastructure visibility without mandatory cloud telemetry.

Organizations retain control of their logs, retention policies, enrichment workflows, and operational visibility.

The appliance is intentionally optimized for practical deployment on modest SMB infrastructure.
