AI code review: what it actually catches versus misses
GitClear's 211M-line study found copy-pasted code rose from 8.3% to 12.3% of changes from 2020 to 2024 — even as AI reviewers flag more comments, the defects that matter most still slip through.
Where AI actually helps AppSec — and where it quietly makes things worse
One 2025 benchmark found an LLM filter cut Semgrep's false positives by 88.6% — while a separate study found GPT-4 alone flagging vulnerabilities was wrong more often than right.
How AI-powered SAST auto-fix engines actually work
GitHub says Copilot Autofix resolves two-thirds of flagged vulnerabilities with little editing; Snyk claims 80% fix accuracy. Here's the pipeline behind both numbers.
ASPM fundamentals: what application security posture management actually aggregates
Gartner coined the ASPM term in May 2023 and projects over 40% of organizations building software will adopt it by 2026 — here is what it actually does.
A practical AppSec maturity model: five stages, self-assessment included
OWASP SAMM v2 scores 15 practices on a 0–3 scale; BSIMM15 measured 121 firms and found SCA adoption up 67%. Here's a five-stage model to self-assess against.
What to Evaluate in an ASPM Solution: A 2026 Buyer's Guide
Gartner named Application Security Posture Management a category in May 2023 — three years later, most RFPs still can't distinguish a real ASPM from a dashboard bolted onto old scanners.
