Fundamentals Drafting

What is Proof-Driven AppSec?

Why validated evidence, not alert volume, should decide what your team fixes, and how AI Swarm Pentest, Deep Code Analysis and Remediation fit together. A one-page primer that doesn't require a vendor demo.

Deep dive Drafting

AI Swarm Pentest vs. a traditional pentest

What changes when attack paths are validated by coordinated agents inside an agreed scope, what the report looks like, and which decisions still belong to a human reviewer.

Compliance Drafting

NIS2 for AppSec teams

NIS2 Directive Article 21 imposes specific software-supply-chain security requirements on essential and important entities across the EU. What it actually says, who it applies to, and what evidence you need to produce.

Deep dive Drafting

Beyond pattern-matching SAST

Why pattern-matching SAST tools surface noise and miss exploits, and what deep semantic code analysis does differently — unifying syntax, control flow, and data dependence into a queryable understanding of the codebase. The difference between "this looks suspicious" and "this is exploitable".

Securing AI-generated code — a developer guide

Cursor, Copilot, Claude Code, Windsurf, Devin, Replit — the AI assistants your team uses ship vulnerable code by default. A practical guide to keeping productivity high while the security posture holds.

AI Swarm Pentest — proving exploitability with real PoCs

The difference between a SAST finding (theoretical) and an AI Swarm Pentest finding (a working PoC running against your sandbox). Why your board will only fund the fixes for the second kind.

Compliance Coming soon

CRA — the Cyber Resilience Act for software vendors

The EU's Cyber Resilience Act mandates secure-by-design and vulnerability handling for nearly all software sold in the EU after 2027. What "secure by design" means in audit terms, and what changes about your SBOM workflow.

Slopsquatting — when your AI imports a package that doesn't exist

LLMs hallucinate package names. Attackers publish real packages with those names. The result is a supply-chain attack vector unique to the AI-coding era. How to detect, how to block, and what we found scanning 10,000 Lovable apps.

Validate, understand, remediate: the Proof-Driven workflow

How a finding moves from a validated attack path to a reviewed change: what AI Swarm Pentest, Deep Code Analysis and Remediation each contribute, and where your team keeps the final decision.
