Identifies feature flag configurations patterns in security and access control contexts. Detects potential exposure of sensitive security information in international systems.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: category-aware structural regex with anchor and context constraints replaces phrase-only detection. Added context gating and exclusion rules improve precision and reduce incidental matches.
Detection quality: Mixed
Jurisdictions: global
Regulations: GDPR
Data categories: credentials, security
Scope: wide
Platform compatibility: Purview: Compatible, GCP DLP: Compatible, Macie: Compatible, Zscaler: Compatible, Palo Alto: Degraded, Netskope: Unsupported

(?is)\b(?:feature\s+flag|feature\s+toggle|launch\s+darkly|environment\s+variable|canary\s+release|dark\s+launch|kill\s+switch|flag\s+management|remote\s+config)\b

Corroborative evidence keywords

feature flag configurations, feature, flag, configurations, software, engineering, architecture

Proximity: 300 characters

Should match

feature flag — Primary topic phrase match
feature toggle — Case-insensitive topic phrase match
launch darkly — Alternative topic phrase match
environment variable — Additional topic phrase match

Should not match

unrelated generic text without domain phrases — No relevant topic phrases present
placeholder value 12345 — Random text should not match topic-specific regex
source code config — Generic word pair from old broad template should not match

Known false positives

Authentication-related terminology in software documentation, security training materials, or system architecture descriptions without actual credentials. Mitigation: Require proximity to credential-specific patterns (API keys, connection strings, tokens) rather than general security terminology.
Code snippets and configuration examples containing credential-related keywords or placeholder values in developer documentation. Mitigation: Check for common placeholder patterns (example.com, localhost, 0000) and documentation file types to reduce false positives from technical writing.
