DevGuard vs StepSecurity

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.

StepSecurity is a software supply chain security platform spanning developer environments, code repositories, and CI/CD pipelines. Harden-Runner uses eBPF to monitor network calls, file writes, and process executions, then relates activity to workflow steps. Dev Machine Guard inventories AI coding agents, MCP servers, IDE extensions, and local packages on developer machines. Secure Registry provides package cooldowns, blocks compromised versions, and offers typosquat protection and blocklists. Code Repo Security screens pull requests and can open remediation pull requests according to policies. Security alerts can go to email, Slack, or Microsoft Teams. Dev Machine Guard can be deployed without an agent through Intune, SCCM, or Jamf on macOS, Windows, and Linux. The Community plan is free for unlimited public repositories and lists GitHub-hosted runners on GitHub Cloud; private repositories are included in the 14-day trial. Dev Machine Guard costs $8 a month per device, while Enterprise costs $16 a month per contributing developer. The Trust Center lists SOC 2 Type 2 and ISO 27001:2022 compliance.
