What it sells: Minimus

What Minimus Images does[1][4][5][6][8]
Minimus images contain only the software needed to run an application, with shells, package managers, and network utilities stripped out.

What it sells: Phoenix Security

What Phoenix Purple does[1][2][5][7][8][9][14]
Phoenix Purple is an engineering-first application security platform. It connects directly to AI coding agents and delivers fixes as pull requests instead of tickets. Phoenix Purple runs deterministic SAST and SCA on a knowledge graph, adding reachability, a chainability map, and one-click assessment and remediation. Phoenix Purple is available in general availability.
What Phoenix Orange does[2][5]
Phoenix Orange answers what to fix and in what order. It aggregates every scanner into a single queue, strips out unreachable noise, attributes findings to the right team, and connects code-level findings to the cloud service where they run.
What Phoenix Green does[5]
Phoenix Green writes the fix as a pull request with the threat context already in the description. Risk tiering sets the path: safe changes move fast, moderate ones carry a review flag, and anything breaking or dangerous needs explicit human approval before it can merge.
What Purple Hook does[9]
Purple Hook is a local check that runs inside the AI coding assistant developers already use. It is generally available for Phoenix Purple customers.

About Minimus

Minimus sells minimal container images that it rebuilds from upstream source, with only the packages needed to run the application. Minimus is winding down operations, and Echo has acquired key Minimus technology and assets. Minimus says it is working with the Echo team and meeting with every Minimus customer to provide support during the transition period.

Minimus images contain only the software needed to run the application. Minimus images have shells, package managers, and network utilities stripped out. Minimus builds its images from source continuously, and the images are OCI-compliant, with FIPS 140-3 modules available. Minimus compiles each application in a SLSA 3 build environment from upstream project source code and includes only the libraries the application needs to run. Minimus monitors tens of thousands of open source projects and rebuilds images in a SLSA Level 3 pipeline when updates occur. Minimus provides images for LLM, app development, and cloud native infrastructure.[5][6]

Minimus gives a contractual guarantee of zero known CVEs at delivery, with a 48-hour remediation SLA for newly disclosed vulnerabilities. Minimus patches critical CVEs within 48 hours of upstream availability, and high and medium CVEs within 14 days. Minimus sets a 24 hour SLA for critical and high CVEs on KEV, and 48 hours for all other critical and high CVEs. Minimus offers FIPS 140-3, STIG, NIST and CIS ready images for sensitive workloads. Minimus images come with automated testing and documented results per build, and support FedRAMP, DORA, and NIS2 posture requirements. Minimus is both SOC-2 and ISO 27001 certified, and Minimus makes the reports available by request.[5][6][7]

Minimus lets customers configure their own hardened container images, and Minimus takes care of the updates and maintenance. Customers can build atop the thousands of secure base images from Minimus. Minimus draws real-time threat intelligence from EPSS, CISA-KEV, and Minimus Labs to prioritize upstream vulnerabilities by actual likelihood of exploit.[5][6]

Minimus offers Actions to integrate with tooling such as GitHub, Slack, and webhooks. Minimus automatically triggers events in Slack, Jira, GitHub, and more. Minimus connects to development, chat, and ticketing tools and to the rest of a security stack. Minimus provides skills and config tools for Claude, Codex, Cursor, and more to migrate to and build on Minimus images.[5][6]

Minimus offers a SaaS management console, and images can be pulled from the Minimus registry or from whatever registry a customer uses, including air gapped ones. Minimus supports pulling from the registry of your choice, with fully air-gapped support available, and Minimus publishes Hardened Helm Charts versioned by Minimus. Minimus can sync images to the registries a customer already uses, even air-gapped ones. Minimus images are API-compatible with what customers already run, and the change is an update to the Dockerfile followed by a rebuild.[5][6]

Minimus offers open access to hardened images for everyone, with an upgrade for private builds, SLA-backed support, and the controls enterprise teams need. Minimus offers 1,000s of near 0 CVE images built from source. Minimus is built for the needs of enterprise security teams and fast moving developers. Global financial institutions and startups are named as customers of Minimus. The Minimus founders created Twistlock, which Palo Alto Networks acquired, and authored NIST SP 800-190, the federal standard for container security. Minimus has a global team that provides round-the-clock support, 365 days of the year.[5][6][7]
