What is web application security?
Web application security sits at the intersection of software development and cybersecurity. It covers everything that protects your app at the code level, securing your database, hardening your API routes, managing secrets, implementing compliance, and making sure edge cases don't become your first breach.
Most apps ship without it. Attackers know this.
#1 missing control
Row Level Security, the most commonly skipped protection in Supabase projects
OWASP Top 10
The industry-standard checklist every production app must pass before launch
4% of revenue
Maximum GDPR fine for non-compliant data handling, or €20 million, whichever is higher
Every layer, covered.
Our packages are structured in the order that makes your app most secure, fastest.
Row Level Security
Every Supabase table locked down with policies so users can only access their own data. Without this, your entire database is readable from the browser console.
Server-side validation
Every API route that writes data validates input on the server, not just the client. Strict schema enforcement prevents mass assignment and injection attacks.
Rate limiting
Brute-force and credential stuffing protection on all auth endpoints. Sliding window algorithm, HTTP 429 responses, and Retry-After headers.
Headers & OWASP audit
Full HTTP security header implementation (CSP, HSTS, X-Frame-Options, and more) plus a structured OWASP Top 10 audit with a written findings report.
Compliance pages
Privacy Policy, Terms of Service, Cookie Policy, and GDPR/CCPA data request forms, built and linked before your first user signs up.
