The Growing Threat

The Threat is Real

Supply chain attacks have surged in frequency and sophistication, targeting the software you trust every day.

2020

SolarWinds

$18B+ damage

Malicious code injected into build pipeline. 18,000+ organizations compromised including US government.

2021

Codecov

Secrets exposed

Modified bash uploader exfiltrated CI/CD secrets from thousands of repositories.

2021-2024

npm attacks

Millions affected

2024

xz-utils

Critical infrastructure

Backdoor planted in release tarballs only — source code looked clean. Multi-year social engineering attack.

How It Works

From Source to Blockchain

Every package goes through a 5-step verification pipeline before it reaches your production environment.

Rebuild

Package is rebuilt from source code in an isolated container — no network access during build

Compare

Published package is compared byte-by-byte against the one rebuilt from source

AI Scan

AI analyzes the code for malicious patterns — backdoors, credential theft, obfuscation

Sign & Store

Cryptographically signed and uploaded to decentralized storage (IPFS)

Record

Proof of verification recorded on the blockchain — immutable and tamper-proof

Install

Developers in your org install packages through SourceSeal's proxy — only verified packages get through

Trust Level 5 — Rebuilt & Verified
