Web application security is non-negotiable in 2026. The OWASP Top 10 — including injection attacks, broken authentication, and XSS — remains the primary threat landscape.
Implement HTTPS everywhere, use parameterized queries to prevent SQL injection, sanitize all user inputs, and enforce strong authentication with MFA. Regular penetration testing and dependency scanning catch vulnerabilities before attackers do.
Security should be built into the development lifecycle (DevSecOps), not added as an afterthought before launch.
