Expert articles on web security, vulnerabilities, and best practices
ProductUse Vulnify's free tools in a deliberate 20-minute sequence to check TLS, headers, CSP, DNS, email, exposed paths, libraries, redirects, subdomains, and compromise signals.
Best PracticesRetire old API versions deliberately by inventorying clients, comparing security controls, monitoring usage, revoking credentials, and removing legacy routes and infrastructure.
Best PracticesCombine Subresource Integrity with Content Security Policy to pin stable third-party assets, constrain script sources, and reduce supply-chain risk without blindly breaking integrations.
Best PracticesUnderstand how sensitive URL values spread through logs, history, telemetry, and referrers, and how to design safer reset links and API authentication.
SecurityUse Certificate Transparency logs to find historical hostnames, unexpected certificate issuance, forgotten infrastructure, and gaps in your domain asset inventory.
Best PracticesUse browser-enforced cookie prefixes to reduce session-cookie scope and configuration mistakes, while keeping HttpOnly, SameSite, CSRF, and session lifecycle controls intact.
Best PracticesUnderstand which frontend keys are intentionally public, why NEXT_PUBLIC and VITE values are exposed, and how to keep privileged credentials on the server.
Best PracticesDesign API rate limits around sensitive operations, identities, resource cost, batching, and third-party spending instead of relying on one generic 429 threshold.
SecurityUnderstand where OS command injection appears in web applications and how to prevent it by removing shell use, separating arguments, validating input, and limiting process privileges.
SecurityUnderstand the difference between path traversal and local file inclusion, where they appear, and how to design file handling that avoids both.
