In-depth guides on vulnerability detection, OWASP Top 10, secure configuration, and web performance — written for developers and security professionals.
A practical breakdown of all 10 OWASP vulnerability categories, what changed from 2017, and how to detect and fix each one in your web application.
SQL injection remains one of the most devastating web vulnerabilities. Learn how to detect all three types — classic, blind, and time-based — and how to fix them permanently.
XSS is one of the most common web vulnerabilities. Understand the three types — reflected, stored, and DOM-based — and learn the right prevention techniques for each.
A misconfigured TLS setup can expose encrypted traffic, allow downgrade attacks, and fail compliance audits. Here are the most common mistakes and how to fix them.
Security headers are the fastest way to harden a web application. This guide covers every important header, what it does, and the exact values you should set.
A misconfigured CORS policy can allow any website to make authenticated requests to your API. Understand how CORS works, what goes wrong, and how to configure it correctly.
Broken Access Control is the most prevalent vulnerability in web applications today. Understand IDOR, privilege escalation, path traversal, and how to implement proper authorization.
Performance directly impacts user experience and SEO rankings. Learn how to measure and improve DNS lookup times, TTFB, page weight, caching, and HTTP/2 adoption.
HTTP Strict Transport Security prevents browsers from ever connecting to your site over plain HTTP. Here's how it works, how to implement it, and how to get on the HSTS preload list.
Automated vulnerability scanning is the foundation of a continuous security program. Learn how scanners work, what they can and cannot find, and how to integrate scanning into your development workflow.
Manual code review and developer intuition are not enough. Here is why automated vulnerability scanning is a non-negotiable part of any web security program.
Clickjacking tricks users into clicking hidden UI elements by overlaying your site in an invisible iframe. One header prevents it entirely — here is what you need to know.
Session cookies are the keys to your users' accounts. Missing cookie flags are one of the most common findings in security audits. Here is how to set them correctly.
SSRF lets attackers make your server fetch arbitrary internal URLs — reaching cloud metadata APIs, internal services, and firewalled systems. It is now in the OWASP Top 10.
Version headers, stack traces, and debug endpoints give attackers exactly what they need to plan targeted attacks. Here is what to hide and how.
A forgotten DNS record pointing to a decommissioned service can allow an attacker to claim that subdomain and serve malicious content under your brand's domain.
CSP is the most powerful browser security mechanism available, but it is also complex to implement correctly. This guide walks you through building a strict, effective policy without breaking your site.
A WAF is a valuable layer of defense, but it is not a security solution on its own. Understand what WAFs block, where they fail, and how to use them correctly.
Shifting security left means catching vulnerabilities during development, not after deployment. Here is how to build security checks into your CI/CD workflow without slowing down delivery.
Open redirects let attackers craft legitimate-looking URLs that send users to malicious sites. They are frequently used in phishing campaigns and OAuth token theft.
A practical guide to earning the Shieldome security certificate: how grading works, which vulnerabilities affect your score most, and why an embeddable badge builds real user trust.
