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.
NHIMG editorial — based on content published by Wazuh: Open source software is increasingly seen as the future of cybersecurity
By the numbers:
- 90% of the world’s web servers run on open source software, underscoring how deeply transparent code shapes modern infrastructure.
- 85% adoption across industry software stacks shows that open source is already embedded in most enterprise environments.
Questions worth separating out
Q: What breaks when organisations trust software they cannot independently verify?
A: Blind trust breaks the ability to distinguish legitimate code from compromised code, which means attackers can hide in the build process, update path, or runtime behaviour.
Q: Why does open source reduce supply-chain risk without eliminating it?
A: Open source reduces risk by making code and release processes more inspectable, which improves discovery and accountability.
Q: How can security teams tell whether transparency is actually improving control?
A: Look for measurable reductions in time to detect, time to verify, and time to remediate after a flaw is disclosed.
Practitioner guidance
- Require provenance evidence for deployed software Block production use of software unless you can trace its source, build path, signing status, and release ownership.
- Map open source dependencies to critical workflows Create an inventory that links libraries, containers, appliances, and update channels to the business services and identity flows they support.
- Validate remediation, not just patch receipt After applying a fix, verify that the affected system no longer exposes the vulnerable behaviour, backdoor, or persistence mechanism.

Wazuh's full blog post covers the operational detail this post intentionally leaves for the source:
- The full breakdown of the SolarWinds, Barracuda, Exchange, and Ivanti cases, including how each compromise progressed in practice.
- The article's discussion of open-source development processes, including static analysis, dynamic analysis, and independent security audits.
- The community and CTI sections that show how contributors, researchers, and operators share findings in real time.
- The article's references to SBOM-driven compliance expectations and how transparency links to procurement decisions.

Open source transparency is becoming a governance baseline, not a niche preference. The article’s central claim is not that open source is automatically safe, but that security claims become testable when code, build paths, and release logic are visible. That shift matters because opaque systems force defenders to trust assertions they cannot independently validate. Practitioners should treat verifiability as part of control design, not as an optional property.
A question worth separating out:
Q: Who should be accountable when software trust controls fail?
A: Accountability should sit with the teams that own publisher identity, certificate issuance, and software release governance together. If those functions are separated, trust breaks down because no single group can see the full lifecycle from identity proofing to distribution.
