Best SBOM Tools in 2026, Compared | Blog | Endor Labs

What it is

An Endor Labs comparison of five SBOM tools, grouped by capability layer. The value beyond the summary is the per-tool format constraints and trade-offs that actually drive a selection decision.

Preconditions / Affected

Relevant if you are choosing an SBOM tool and care about output format compatibility, language coverage, or deployment weight. Note the guidance culminates in Endor's own commercial product (SBOM Hub), so weigh the framing accordingly.

What to do

Match tool to constraint, using the concrete differentiators the page gives:

• Output format is the first filter. Syft exports both SPDX and CycloneDX. cdxgen is CycloneDX-only (no SPDX). Microsoft SBOM Tool is SPDX 2.2-only. If your consumers mandate a format, this eliminates candidates before anything else.
• Coverage vs. overhead. cdxgen has the broadest language support (Java, JS, Python, C++, more) but runs slower than Syft on large codebases. Syft covers 30+ ecosystems, is lighter/faster, and pairs with Grype for scanning. Microsoft's tool is Windows/Azure/.NET-centric with more configuration required.
• Generation is not management. Syft, cdxgen, and the Microsoft tool only produce inventory. For storage, versioning, policy, and continuous monitoring you need a platform — OWASP Dependency-Track (open source, requires a database) or SBOM Hub (commercial).
• Noise reduction. The page's central pitch: pure CVE matching floods teams; function-level reachability filters to findings an attacker can actually reach. Only SBOM Hub (commercial) offers this here; Dependency-Track does monitoring without reachability.

Caveats

• Stated metrics are the vendor's: basic generators "miss up to 40%" of dependencies in complex builds; SBOM Hub claims reachability cuts "95% of noise." Both are Endor's figures, unverified here.
• Manifest-parsing generators (Syft called out) can miss shadow/phantom dependencies — a coverage gap the platforms are positioned to fill.
• The fetched text is truncated mid-section ("How to choose for your stack"), so the full stack-by-stack recommendation list is incomplete.
