Secured before it enters your stack – continuously until the end-of-life date.
All the ecosystem benefits. None of the blind trust.
SecureChain for Open Source Software
A hardened PHP supply chain – trusted at install, malware-screened, and protected for as long as it remains in your stack
SecureChain replaces Packagist with a verified, rebuilt-from-source alternative. It vets every package during installation, continuously delivers vulnerability fixes, and keeps PHP dependencies protected long after maintainers stop releasing updates.
Coverage across the ecosystems behind today’s production stacks
PHP’s Dependency Model Carries Hidden Risk
Packagist underpins most modern PHP applications.
But its open model makes it vulnerable to abuse.
From compromised maintainers to abandoned packages, risk accumulates quickly.
One ecosystem. Persistent exposure.
-
PHP Git server compromise
Backdoor commits planted in PHP's official source. Caught before release, but a reminder that the runtime itself is part of the attack surface.
-
Abandoned package exploitation
Widely used libraries left unmaintained and later targeted as vectors for attack.
PHP applications outlive the packages they depend on.
How risk enters your PHP dependencies
Risk is built into how Composer resolves and installs packages.
At every composer install and update
Each composer install pulls from a public registry.
That trust can be exploited.
- Hijacked packages
- Tampered releases
- Malicious scripts
- Dependency confusion
Everything that happens after maintenance stops
Each composer install pulls from a public registry.
That trust can be exploited.
- Projects are abandoned
- Security fixes stop
- New CVEs continue to surface
Your application keeps running them anyway.
PHP security solutions cover one layer each.
The risk lives in the gaps. SecureChain doesn't leave any.
SecureChain is different because it's not advisory – it's active.
And it doesn't stop when the maintainer does.

The Speed and Flexibility of Open Source,
Without the Risk.
With SecureChain, every package is:
Rebuilt and verified
Every package is rebuilt from source in hardened, isolated environments — no inherited binaries, no opaque upstream artifacts. What you install is what was built, verified end to end.
Malware-scanned
Every package is screened for known malware, suspicious code patterns, and supply chain risks. Anything that fails inspection is blocked before it reaches your environment.
Continuously patched
Active components are monitored and patched under SLA as CVEs emerge. When upstream maintenance ends, Endless Lifecycle Support (ELS) keeps delivering fixes for as long as you depend on the package.
Compliant and audit-ready
Know exactly what’s running and what’s been patched. SLSA Level 3 provenance, SBOM, and VEX deliver complete supply chain assurance — the evidence your auditors need on demand.
+ On-demand coverage
If a package you depend on isn’t in the catalog yet, we’ll add it
at no additional cost: verified, patched, and supported like every other.
Built for teams who own the risk:

Frequently Asked Questions
Usually not from Packagist itself. Packagist acts as a directory that points Composer to external repositories such as GitHub or GitLab, where code is fetched at install time. SecureChain replaces that model with a controlled repository where every PHP package is verified before delivery.
Composer installs can introduce more risk than teams expect. Composer can execute scripts defined in composer.json, and dependencies may include code that runs during install or application startup. SecureChain reviews the source code for these behaviors and blocks malicious PHP packages before they reach your environment.
They can be very large. Frameworks such as Laravel and Symfony can bring in well over a hundred transitive packages. Many are never manually reviewed, but they still affect application security. SecureChain verifies, scans, and continuously patches every dependency in the PHP package tree.
You need control over what gets installed and how it behaves. SecureChain provides a verified source of Composer packages, blocks malicious ones, and continuously patches vulnerabilities across the full dependency tree.
No. SecureChain continuously monitors vulnerabilities and delivers validated fixes to the versions you run, reducing the need for manual Composer auditing.
Security fixes stop, but vulnerabilities continue. SecureChain is complemented by Endless Lifecycle Support for PHP packages, allowing you to stay secure without immediately upgrading frameworks or rewriting code.
No. SecureChain is a drop-in replacement. Developers continue using the same Composer commands and workflows.
