AI Semantic Search for Cybersecurity Sites

March 5, 2026

Prototype: https://ai-website-cybersecurity-company.vercel.app/

The Problem

Keyword search fails security buyers. A CISO typing "cloud misconfiguration risk" gets zero results if your page says "CSPM posture drift." Same intent, different words.

The Solution

  • Convert all site content into vector embeddings via OpenAI
  • Store vectors in Supabase using pgvector extension
  • On search: embed the query → find nearest vectors via cosine similarity
  • Return results ranked by semantic relevance, not keyword match

Use Cases

  • "Broken API" → surfaces webhook, integration, GraphQL docs
  • "Compliance audit" → finds SOC 2, ISO 27001, HIPAA pages
  • "Who monitors my cloud?" → returns CSPM and MDR service pages

Tech Stack

  • OpenAI Embeddings API (text-embedding-3-small)
  • Supabase + pgvector extension
  • n8n (optional: automate re-indexing on content updates)

Target Audience

Security founders running content-heavy sites with 10+ service/blog pages

Impact

Prospects find the exact service they need in one query. Reduces bounce rate from navigation confusion - especially critical when pitching GRC or MDR services to time-poor CISOs.
