When a critical CVE drops in a library buried three layers deep in your dependency tree, the question your customers actually want answered isn't "is this component present" — it's "are we affected." That's the gap VEX tools are built to close. Vulnerability Exploitability eXchange (VEX) documents let a software producer make an authoritative, machine-readable statement about whether a known vulnerability is actually exploitable in a given product: affected, not affected, fixed, or under investigation. Paired with an SBOM, VEX turns a wall of CVE noise into a short, actionable list. But "VEX tool" covers a lot of ground, from CLI generators that stamp out OpenVEX statements to full platforms that ingest, correlate, and act on VEX at scale. This guide walks through what actually matters when evaluating VEX tools, then reviews six real options on the market today.
What to Look for in VEX Tools
Not every VEX tool solves the same problem. Some are built to help vendors author VEX statements; others are built to help downstream consumers filter scanner noise using VEX someone else published. Before comparing products, it helps to separate the market into the criteria that actually predict whether a tool will fit your workflow.
Format Support: CycloneDX, OpenVEX, and CSAF
VEX isn't a single file format — it's a concept implemented differently across ecosystems. CycloneDX has a native VEX profile, OpenVEX is a minimal JSON-based spec backed by the OpenSSF, and CSAF (Common Security Advisory Framework) VEX is favored in OT/ICS and government contexts, including CISA's own guidance. A tool that only speaks one dialect will eventually force you into manual conversion or a second tool. Look for explicit, tested support (not just "JSON import") for the formats your customers or regulators actually require.
Generation vs. Consumption
This is the split that trips up most buyers. VEX document generators are aimed at software producers: they help you attach status, justification, and impact statements to specific CVE/component pairs and publish a signed, versioned document. VEX consumption tools sit on the other side — they take VEX documents (yours or a vendor's) and use them to suppress or de-prioritize findings in a scanner or vulnerability management pipeline. Many platforms claim to do both, but the depth varies enormously; a scanner that can "read" a VEX file to hide a finding is a very different capability from a system that can track VEX status changes over time and alert when a "not affected" claim needs re-review after a dependency update.
Integration with SBOM and Scanning Pipelines
VEX is only useful in context. A VEX statement without the corresponding SBOM is just an opinion with no inventory to attach to. The strongest tools treat SBOM generation, vulnerability scanning, and VEX as one connected pipeline rather than three disconnected exports, so a new CVE against a known component automatically surfaces the relevant VEX status instead of requiring someone to cross-reference two files by hand.
Automation and Status Tracking
Manually authoring a VEX statement for every CVE against every component in a large codebase does not scale. Better tools support bulk status assignment based on rules (e.g., "not affected" for CVEs in test-only dependencies, or components below a reachability threshold), and — critically — support revisiting a status when the underlying code, version, or usage context changes. A VEX statement is a claim about a point in time, not a permanent exemption, and tooling that treats it as permanent will eventually produce stale, misleading data.
Interoperability and Community Trust
Because VEX is meant to travel between organizations — vendor to customer, customer to auditor — lock-in defeats the purpose. Favor tools built around open specifications with active community governance (OpenSSF, NTIA-descended working groups, OASIS for CSAF) over proprietary formats that only your one vendor's platform can read.
Six VEX Tools Worth Evaluating
With those criteria in mind, here's an honest look at some of the more established options in the vulnerability exploitability exchange software space today. None of these is a perfect fit for every organization — the right choice depends heavily on whether you're primarily producing or consuming VEX, and how deeply VEX needs to integrate with your existing SBOM and scanning stack.
Dependency-Track (OWASP) is a free, self-hosted component analysis platform that has built out real VEX support over several release cycles, including CycloneDX VEX import and export tied to its policy engine. Its strength is that VEX isn't bolted on — it lives alongside the same SBOM inventory and vulnerability data the platform already tracks, so a VEX statement can directly suppress a finding in the same view your team already uses. The tradeoff is that it's a self-hosted Java application you need to operate and scale yourself, and its VEX authoring workflow is still more utilitarian than polished, with limited support for CSAF-style documents.
GUAC (Graph for Understanding Artifact Composition), an open-source project incubated with backing from Google and the OpenSSF, takes a graph-database approach to ingesting SBOMs, VEX documents, attestations, and other supply chain metadata into one queryable model. It's genuinely powerful for large organizations that need to answer cross-cutting questions like "which of our deployed artifacts are affected by CVE-X across every VEX statement we've ever ingested." The cost is complexity: GUAC is an ingestion and query layer, not a turnkey product, and stands up a nontrivial amount of infrastructure (a graph database and multiple collector services) before it delivers value.
OpenVEX and vexctl, maintained under the openvex GitHub organization with contributions from Chainguard and others, define a deliberately minimal VEX format and ship a lightweight CLI (vexctl) for creating, merging, and attesting VEX statements. It's arguably the easiest entry point if you just need to start publishing VEX documents without adopting a platform, and its simplicity makes it easy to script into CI. The limitation is that it's a building block, not a management system — there's no built-in dashboard, history, or bulk workflow for tracking hundreds of statements over time, so most teams end up wrapping it in their own tooling as volume grows.
Anchore's Grype and Syft are widely used open-source scanning and SBOM tools, and Grype supports consuming VEX documents (including OpenVEX) to suppress matches during a scan, which makes it one of the more practical VEX consumption tools for teams already using it in CI. Anchore Enterprise extends this with policy-driven VEX handling. The catch is that Grype's VEX support is primarily about filtering scan output — it isn't designed to help you author well-justified VEX statements in the first place, so it works best paired with a separate generation workflow.
Trivy (Aqua Security) is one of the most widely deployed open-source scanners, and it added the ability to ingest VEX documents to filter reported vulnerabilities, similar in spirit to Grype. Its advantage is sheer reach — Trivy is already embedded in countless CI pipelines, container registries, and Kubernetes admission controllers, so VEX filtering rides along with a tool teams already run. As with Grype, though, VEX support here is consumption-focused; Trivy isn't the tool you'd reach for to produce and manage VEX statements for your own software.
Interlynk offers a commercial SBOM and VEX management platform built specifically around the producer side of the equation — helping vendors generate, sign, host, and version VEX documents alongside SBOMs, with an emphasis on the compliance and distribution workflow (getting VEX into customers' hands in a format they can consume). Its strength is treating VEX as a first-class deliverable rather than a scanner feature. Being a newer, narrower commercial platform, it has a smaller install base and community footprint than the open-source options above, and adopting it means adding another vendor relationship rather than extending tools you may already run.
Across all six, a pattern holds: open-source scanner-adjacent tools (Grype, Trivy) are strong VEX consumption tools but weak at authoring; CLI-first projects (vexctl/OpenVEX) are strong at authoring but leave management to you; and platform-style tools (Dependency-Track, GUAC, Interlynk) trade some simplicity for the ability to actually operate VEX at scale across many components and vulnerabilities over time.
How Safeguard Helps
Evaluating VEX tools in isolation only gets you halfway, because VEX is worthless without accurate, current knowledge of what's actually running in your environment and whether a given vulnerability is reachable in practice. Safeguard is built for that connective layer: continuous SBOM generation across your build and deployment pipeline, reachability and exploitability analysis that gives your VEX statements real evidence behind them, and a workflow for tracking VEX status over time so "not affected" doesn't quietly go stale after the next dependency bump. Rather than asking your team to choose between a generator and a consumption tool, Safeguard ties SBOM, vulnerability data, and VEX status into one pipeline — so a new CVE against a component you already ship arrives with the context needed to make (and defend) a VEX determination, and so your customers receive VEX documents backed by actual analysis rather than a best guess. If you're assembling a VEX toolchain and want to see how that connective layer fits alongside the tools reviewed here, we're happy to walk through it.
