Static Application Security Testing (SAST)
SAST scans source code for exploitable flaws before deployment. Learn how it works, how it differs from DAST/SCA, and where it falls short.
How Does SAST Work? Stages of SAST Scanning
A stage-by-stage breakdown of how SAST scanning actually works — parsing, taint analysis, false positives — with real CVEs and benchmark data.
SAST vs DAST: Key Differences
SAST reads code before it runs; DAST attacks it while it's live. Here's what each catches, what each misses, and when to run both.
SAST vs SCA Testing
SAST scans the code you wrote; SCA scans the code you imported. Here's the real difference, with Equifax, Log4Shell, and xz as case studies.
Code Review vs Static Analysis
Code review and static analysis catch different bugs at different gates. Here's how they differ, where each fails, and how to combine them.
Checkmarx CxSAST: What It Actually Does
Checkmarx CxSAST is one of the longest-running static analysis engines in the enterprise appsec market. Here's what it actually scans, how it's typically deployed, and where teams run into friction.
Free Online Code Checkers: What They Actually Catch
An online python code checker or a free JS linter will catch syntax errors and style issues fast, but here is exactly where that coverage ends and real security scanning has to start.
Static Analysis vs Dynamic Analysis
Static analysis reads code before it runs; dynamic analysis watches it execute. Here's how the two differ, catch different bugs, and work best together.
CodeQL vs Semgrep: A 2026 Buyer Comparison
A practical head-to-head between CodeQL and Semgrep in 2026: query power, performance, rule authoring, and where each tool earns its place in a modern SAST program.
Checkmarx vs Fortify: A Practical Comparison
Checkmarx and Fortify solve the same SAST problem with different architectures — here's how they actually differ on accuracy, deployment, and total cost.
What is Taint Analysis
Taint analysis traces untrusted input from source to sink to catch injection flaws. Learn how it works, what it misses, and how reachability analysis fixes the noise.
What is Abstract Syntax Tree (AST) Analysis
AST analysis parses code into a tree to catch what regex scanning misses — here's how it works, its limits, and how reachability fixes the gap.
