SYSTEM ARCHITECTURE

Four-Stage Multi-Modal Detection Pipeline

Engineered to resist adversarial prompt engineering, obfuscation techniques, and cross-channel pivot attacks.

01

Cryptographic Header Auditor

Verifies SPF alignment, DKIM cryptographic RSA-SHA256 signatures, and DMARC enforcement policies in inbound MIME streams.

02

Bi-Encoder Semantic NLP

Quantifies artificial time pressure, fear extortion, authority impersonation, and social engineering pretexting markers.

03

IDN & Homoglyph Resolver

Detects visually deceptive Cyrillic, Greek, and Punycode characters (e.g. рaypal.com) and high-risk disposable TLD registries.

04

Explainable SOC Playbook

Maps threat vectors to MITRE ATT&CK techniques with weighted factor attribution and automated SIEM quarantine actions.
