Emphere

Emphere is a container security and remediation company that maps a customer's existing Dockerfile to its own maintained supply chain of hardened base images, runtimes, libraries and services, then rebuilds and patches those images without requiring changes to the customer's Dockerfile. Rather than asking teams to adopt a new base image, the product substitutes Emphere-maintained equivalents (for example emphere/ubuntu, emphere/python, emphere/nginx) for the layers it detects and tracks the remaining system libraries, with the stated outcome of zero fixable CVEs across the resulting layers.

The platform monitors upstream package releases at source — the site cites 1,847 packages tracked, 64 releases in a recent week and detection in under five minutes — and runs cascade analysis on each release covering compatibility (for example runtime versions, TLS configuration, ABI changes), dependency impact, security checks (SAST scanning, CVE checks, malware scanning), maintainer and signature trust verification, and operational steps such as CI pipeline runs, staging tests, rollback planning and team notification. Releases that fail analysis can be blocked from promotion; the site illustrates this with a curl release blocked over an undocumented external call flagged by SAST, leaving an earlier version active.

Outputs are rebuilt, Cosign-signed (Cloud KMS) multi-architecture images for ARM64 and AMD64, accompanied by SBOMs and SLSA provenance, pushed directly to the customer's own registry and rebuilt daily. The image catalog spans base operating systems (Alpine, Debian, Ubuntu, Amazon Linux, Red Hat UBI) in standard, slim and minimal variants with CIS or STIG hardening profiles, distroless language runtimes (Python, Node.js, Java/Temurin JRE, Go, Ruby, .NET, Rust), and hardened services including PostgreSQL, Redis, NGINX and RabbitMQ, with more than 1,000 builds cited.

Business model

Emphere sells a managed remediation service layered onto customers' existing container builds: it maintains patched, hardened image components, continuously rebuilds customer images against them, and delivers signed artifacts with SBOMs and SLSA provenance into the customer's registry.

Traction

The website cites more than 1,000 builds, 1,847 packages tracked with 64 releases processed in a recent week, and a customer testimonial describing reaching zero CVEs across a container fleet after a single-line change. It also states the company raised $2.1M in pre-seed funding to build agentic vulnerability remediation.
