Determinate Systems vs DevGuard

Determinate Systems provides an end-to-end Nix toolchain for installation, collaboration, and deployment across developer laptops, CI, cloud, and edge devices. The platform combines Determinate Nix, FlakeHub, and Determinate Secure Packages. Determinate Nix adds lazy trees, parallel evaluation, stable flakes by default, and a native Linux builder for macOS. FlakeHub offers binary caching, private flakes, organization controls, semantic versioning, and deployment of NixOS, Home Manager, and nix-darwin configurations without local evaluation. Secure Packages is a supported Nixpkgs replacement with curated packages and cryptographic signing. It includes CycloneDX 1.5 SBOM generation, policy checks, and vulnerability scanning; critical vulnerabilities are said to be patched within seven days. Distributions receive at least 12 months of support, with one in four receiving 60 months. Platforms listed are Linux, macOS, Windows, and web. A free plan is available.

DevGuard is an open-source developer security platform focused on hardening the software supply chain. It monitors deployed software for newly disclosed vulnerabilities and can create issues when new CVEs affect software. Risk scoring and exploit probability analysis help prioritize findings, while VEX assessment sharing supports review of potential false positives. The platform connects with GitHub and GitLab repositories, CI pipelines, and issue trackers, and can ingest SBOM, VEX, and SARIF inputs from compatible tools. Its scanner CLI supports software composition analysis, static application security testing, and signing attestations. A dependency firewall checks npm, Go, PyPI, and container image requests against a malicious package database and blocks known-bad releases. DevGuard also supports SBOM management, artifact signing, provenance attestations, and release policy gates. The source code is distributed under AGPL-3.0-or-later. The free self-hosted Open Source plan is for public projects with an OSI-approved license; non-commercial FLOSS projects can get SaaS free. Business SaaS costs €449.10 per month on a one-year contract paid yearly and includes 10 users, managed hosting in Germany, and support.
