SentinelDeck Wiki

SentinelDeck is a passive attack-surface monitoring tool for small businesses, agencies, and security consultants.

It helps turn a domain or IP address into a clear security posture report with a risk grade, structured findings, and practical remediation steps.


What SentinelDeck Does

SentinelDeck performs safe, passive checks across public-facing security signals:

  • DNS hygiene
  • HTTP security headers
  • TLS certificate quality
  • Email authentication
  • Certificate transparency footprint
  • Subdomain exposure
  • Lookalike domain risk
  • Public configuration issues

It does not perform intrusive scanning or exploitation.


Quick Start

Run a one-time scan:

pipx run sentineldeck scan example.com

Or with uvx:

uvx sentineldeck scan example.com

Permanent install:

pip install -U sentineldeck
sentineldeck scan example.com

Open the local dashboard:

sentineldeck dashboard

Main Features

Passive and Safe by Design

SentinelDeck only uses normal public lookups such as DNS, HTTP, TLS, and email-related checks.

Risk Grade and Score

Each scan produces:

  • A to F risk grade
  • 0 to 100 risk score
  • Prioritized findings
  • Severity levels
  • Practical remediation steps

Client-Ready Reports

Outputs include:

  • Structured JSON
  • HTML reports
  • Shareable score cards
  • Change reports
  • Dashboard view

Monitoring and Alerts

SentinelDeck can compare scans over time and send webhook alerts when a domain posture changes or regresses.


Common Use Cases

  • Agency website security snapshots
  • Client onboarding checks
  • Small business domain posture reviews
  • Consultant security reports
  • Passive external exposure monitoring
  • Pre-audit discovery
  • Recurring domain monitoring

Safety Model

SentinelDeck is designed for authorized and passive assessment only.

Use it only on:

  • Your own domains
  • Client domains with permission
  • Domains you are authorized to assess

It does not exploit vulnerabilities, brute-force services, or perform aggressive scanning.
