The Challenge
Security tooling for developers is fragmented, paywalled, and bloated with enterprise complexity. We needed a zero-friction toolkit that developers and security professionals could use instantly — no accounts, no cookies, no ads — while still delivering serious analytical depth powered by AI.
The Design
02
The Approach
We designed Nest Cipher around the principle of "scan, analyze, protect" — six focused tools, each solving a specific security problem. The interface is minimal and fast, with dark/light theme support and instant results. Every tool runs AI analysis under the hood while keeping the UX deceptively simple.
The Solution
01
AI Email Analyzer
Drop in suspicious emails and get instant threat scoring with AI-driven analysis of phishing indicators, sender reputation signals, and social engineering patterns.
02
Prompt Injection Tester
Test AI system prompts against 12 known attack vectors — jailbreaks, role confusion, delimiter attacks — with pass/fail results and remediation guidance.
03
Security Headers Scanner
Audit any URL's HTTP security headers with letter grades, detailed explanations, and copy-paste remediation snippets for each missing or misconfigured header.
