What it does
Security-posture and third-party SaaS identification, security headers, CSP, HSTS, email auth, security.txt, plus payments/analytics/auth/CRM/support integrations.
Security Posture & Third-Party Tech-Stack
Scope
Two related lenses on a target:
- Security posture, HTTP security headers, Content Security Policy, HSTS, email auth (SPF/DKIM/DMARC/MTA-STS),
security.txt, certificate practices. - Third-party / SaaS detection, payment processors, analytics, customer support, identity providers, CRM/marketing, error monitoring, A/B testing, social/communication SDKs, media CDNs.
The two are coupled: CSP script-src and DNS TXT verifications reveal third-party services, while third-party domains contribute to the overall security surface.
Signals (input)
- HTTP response headers, security headers, CSP directives, HSTS
- DNS TXT records, SPF, DKIM, DMARC, SaaS verification tokens
- HTML, meta-tag security policies, embedded widgets/iframes
- Loaded JS / script-src URLs and globals
/.well-known/security.txt,/security.txt,/.well-known/change-password
Inferences (output)
- Security score (header coverage, CSP strength, email-auth strength, security.txt presence)
- CSP analysis (unsafe-inline/eval issues, allowed third-party domains)
- Email-auth grade (DMARC policy strength)
- Third-party SaaS catalogue by category, with integration mode (client SDK vs CSP-only vs DNS-only)
Techniques
When to use
- Pre-engagement security baseline
- Mapping supply-chain / SaaS exposure
- Identifying integrations that grant pivot opportunities (Auth0, Stripe webhook surface, Sentry DSN leakage, etc.)
- Phase 3 of tech-stack OSINT
