Security guides your team can ship this week

Built your Next.js app with Cursor or GitHub Copilot? AI assistants are great at writing features — but they consistently miss security configuration. Here's how to fix it in five steps.

If you're building with Cursor, Lovable, or Bolt, you need a security scanner that works as fast as you do. Here's how the top options compare — and which one vibe coders should use.

Based on ZeriFlow scan data across thousands of websites, the average security score sits at 61/100 in 2026. Most sites fail the same five checks. Most sites can gain 15-20 points with a single afternoon of work. Here is what the data shows.

Static application security testing (SAST) catches vulnerabilities in code before they reach production, but the tool landscape is crowded and confusing for small teams. This guide compares seven tools across cost, language support, integration ease, and signal quality.

Most SaaS security incidents are not caused by sophisticated attacks — they stem from deferred basics. This 30-item checklist organizes web application security by category and urgency, giving founders and developers a clear implementation sequence.
