  • Industry standards comparison (OWASP, NIST, CIS)
  • Competitive analysis via public information

Assessment Scope

Created a consolidated security assessment with executive scoring against industry standards, maintaining neutrality while evaluating:

  • • Code execution security measures
  • • Data integrity protection systems
  • • User and system protection mechanisms
  • • Compliance with security frameworks
  • • Competitive security positioning

Sanitized for Public Release

The following details were removed to prevent malicious exploitation:

  • • Specific file names and module paths
  • • Implementation details of security controls
  • • Internal architecture patterns
  • • Specific path examples and validation rules
  • • Cryptographic implementation specifics

Security through proper implementation, not obscurity
