API Security Review

Fixed scope

  • One repository and one API surface
  • Source, configuration, dependency, authentication, and authorization review
  • Evidence-backed findings with severity and remediation, highest-value in-scope patches, and one verification pass

Review boundary: source and configuration analysis by default. Dynamic testing requires a separately signed scope with exact targets, dates, prohibited techniques, an emergency contact, revocation handling, written owner authorization, and hosting-provider policy confirmation. Denial of service, credential attacks, persistence, social engineering, and third-party targets are excluded. No review promises complete vulnerability discovery, compliance, or security.

Community Ops Bot

Fixed scope

  • One Discord or Telegram community
  • Up to three commands, two alert sources, and one administrator role
  • Privacy policy, deletion path, deployment instructions, and one verification pass

Default data posture: only configuration and platform identifiers are stored. Message content is not retained unless the signed scope requires it. Stored platform data is encrypted and deleted when no longer needed; test data and credentials are deleted after verified handoff. Ongoing hosting and operation are excluded. The buyer operates the bot and assumes continuing platform privacy duties after handoff. Signal automation is not offered.
