TL;DR: Open source software is presented as the future of cybersecurity because public code, community review, and SBOM-driven accountability reduce the trust gap that closed systems create, according to Wazuh. The operational lesson is that transparency improves verification, but only when it is paired with disciplined supply-chain control, patching, and runtime monitoring.
Editorial analysis by NHI Mgmt Group, based on content published by Wazuh: “Open source software as the future of cybersecurity”.
By the numbers:
- Open source software powers 90% of the world’s web servers, according to Wazuh.
- Adoption rates for open source software reach up to 85% across industry software stacks, according to Wazuh.
Key questions
Q: What breaks when software supply chains rely on opaque vendor trust?
A: The failure is that defenders cannot independently verify what was built, signed, or shipped, so malicious changes can persist until exploitation exposes them.
Q: Why do SBOMs matter for product security and compliance?
A: SBOMs matter because they show which components are present when a vulnerability emerges.
Q: How should security teams secure open-source software before it reaches production?
A: Security teams should treat open-source software as an external dependency that needs continuous verification, not blind trust.
Practitioner guidance
- Review source visibility for high-trust software Prioritise code-available software for monitoring, remote access, build, and security tooling so teams can verify what the software does before it reaches production.
- Govern build and signing identities Treat CI credentials, signing keys, and package-publishing tokens as high-value NHIs and enforce least privilege, rotation, and offboarding for each one.
- Require artifact verification before deployment Verify hashes, signatures, and provenance evidence for packages and images before promotion into production or privileged environments.
Bottom line: Open source reduces blind trust by making software behaviour and build assumptions more inspectable, but transparency alone does not make deployments secure.

Open source does not make trust disappear, it relocates it into evidence. The decisive advantage is not ideology but inspectability: defenders can validate code, review changes, and assess build integrity with far less dependence on vendor assurance. That improves the quality of governance conversations around provenance and assurance, especially where software sits inside critical infrastructure or identity-adjacent workflows. Practitioners should treat transparency as a control input, not a substitute for controls.
A few things that frame the scale:
- Internal repositories are 6x more likely to contain secrets than public ones (32.2% vs 5.6%), contradicting the assumption that private repos are safe, according to the State of Secrets Sprawl 2026.
- Software supply chain attacks were projected to cost organisations $60 billion in 2025.
A question worth separating out:
Q: What is the difference between open source transparency and secure software assurance?
A: Transparency means the code and process can be inspected. Secure assurance means the organisation has evidence that the software, its dependencies, and its release path are controlled well enough to trust in production. One enables verification, the other proves the control environment is actually working.
