Which password hash actually protects you, what the OWASP Password Storage Cheat Sheet recommends for Argon2id, scrypt and bcrypt, and measured numbers for tuning each one to a verification time your login path can absorb.
Most breaches are not a code bug. They are a public bucket or an over-broad role nobody reviewed. Here is how to use AI for an expert first pass over your cloud, identity, and infrastructure config, and the tools and guardrails that keep it honest.
Assistants like Copilot, Cursor, and Claude Code ship features fast and ship security holes at the same speed. Here are the flaws they reliably produce, with real before-and-after code, and how to use AI to catch them before an attacker does.
AI assistants can now scan your codebase for vulnerabilities and propose patches. Here is how to wire that into a real pipeline, why you still keep a deterministic scanner next to it, and the four places it will lie to you if you let it.
Row-Level Security is one layer, not the whole answer. Real tenant isolation is defense in depth across the data, the API, and the keys, so that no single mistake exposes another customer. Here are the layers and where each one earns its place.
Row-Level Security moves tenant isolation out of every developer's memory and into the database itself. Here is the exact Postgres pattern for a pooled multi-tenant app, plus the four footguns that leak data in production if you miss them.
