DomainIntel API reveals company security and tools via DNS

By PulseAugur Editorial · [1 sources] ·

A developer has created DomainIntel, a free API that analyzes a company's domain name system (DNS) records, SSL certificates, and HTTP headers to reveal their email provider, hiring tools, and overall security posture. By comparing Stripe and GitHub, the tool highlights differing security philosophies: Stripe uses a lean stack with a strict 'reject' DMARC policy, while GitHub employs a broader set of services with a more lenient 'quarantine' policy. This analysis can provide a clearer picture of a company's operational hygiene and security practices than traditional vendor evaluation methods. AI

IMPACT Provides a new method for evaluating vendor security and operational posture by analyzing publicly available domain data.

RANK_REASON New product release (API) providing a novel method for analyzing company infrastructure.
