What is Dynamic Code Analysis
Dynamic code analysis tests running applications to catch exploitable vulnerabilities that static scans and manifest files alone can easily miss.
What is Secure by Design
Secure by Design turns CISA's 2023 guidance and pledge into concrete practice: memory-safe code, no default passwords, and verifiable SBOMs over marketing claims.
What is Secure by Default
Secure by default means software ships in its safest state out of the box. See real breaches, standards, and pledges driving this shift.
What is Risk-Based Vulnerability Prioritization
CVSS alone can't sort 40,000 CVEs a year. Learn how reachability, EPSS, and KEV data cut real risk from noise.
What is a False Positive in Security Scanning
False positives waste security team hours flagging vulnerabilities that aren't actually exploitable. Here's how to spot, measure, and reduce them.
What is Noise Reduction in AppSec Tooling
Most AppSec scans return thousands of findings, but under 5% are ever reachable in production. Here's how noise reduction actually works.
RASP vs IAST: Which to Deploy in 2026
A practical comparison of Runtime Application Self-Protection and Interactive Application Security Testing for 2026, with deployment guidance based on real-world tradeoffs.
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.
What is Semantic Code Analysis
Semantic code analysis traces how data actually flows through code to find real vulnerabilities — cutting false positives that plague pattern-matching SAST tools.
What is Risk Scoring
Vulnerability risk scoring ranks flaws by real exploitability and exposure, not just CVSS severity. Here's how it works and why it matters.
What is Vulnerability Triage
Vulnerability triage ranks scanner findings by real exploitability and exposure, not raw CVSS score, turning an unmanageable backlog into a short, defensible fix list.
