Core Pillars

Security guarantees you can verify

Signed & Verified

Sigstore signatures with transparency log—verify authenticity before every deploy.

Full Provenance (SLSA Level 3)

Tamper-proof build attestations prove exactly how each image was created.

SBOM Included (SPDX/CycloneDX)

Complete dependency inventory for audits, license checks, and incident response.

Rootless by Default

Non-root execution limits blast radius if a container is ever compromised.

The Difference

From vulnerable to verified

Old Way
ImageSentinel
Base OS
Bloated Debian/Ubuntu/Alpine
Hardened minimal base
Attack Surface
Shell, curl, pkg managers, editors
App-only surface
Dependencies
Outdated + transitive CVEs
Secure, version-pinned, sanitized
Maintenance
Patch → scan → patch loop
Automated hardening, always up-to-date
Vulnerability Count
Dozens of High/Critical CVEs
Zero CVEs (verified & signed)
Image Size
Heavy, slow startup
30–60% smaller, faster startup
Compliance
Messy SBOMs
Clean SBOM + signed provenance
Effort
High
Near-zero — just change the FROM line

Example data shown. Verify with our demo images and SBOM.
