Interlynk

Interlynk manages software bills of materials (SBOMs) from generation through supplier exchange and release monitoring. It is a strong fit for security, engineering, and compliance teams responsible for regulated software or devices. The free Community Tier removes per-seat and per-SBOM charges, but teams should verify that its cloud deployment and supported embedded build workflows suit their environment.

Overview

Interlynk combines SBOM generation, ingestion, enrichment, monitoring, and sharing with open-source risk and supplier workflows. That lifecycle coverage is more useful for teams tracking changing components across releases than for organizations seeking only a one-time inventory. It supports both SBOM standards, with vulnerability and license analysis, policy enforcement, SBOM exchange, and release monitoring.

For embedded C/C++ firmware, its lynkctl generator supports IAR, GCC, and CMake builds. That gives teams using those environments a defined route to generating firmware SBOMs; it does not establish a fit for other build systems. The platform is cloud-based, so it is not the choice for teams that require a self-hosted deployment.

Key features

Vulnerability and open-source risk

Interlynk matches components against NVD, GitHub Security Advisories, and OSV, then enriches them with EPSS, CISA KEV, and CWE data. It monitors for newly disclosed vulnerabilities and supports VEX dispositions, which help teams distinguish applicable issues from findings that do not affect their software. License obligations and component maintenance status broaden the view beyond vulnerability counts, making the platform more useful for ongoing component decisions.

Supplier exchange and integrations

Suppliers can submit CycloneDX or SPDX SBOMs through a secure link without creating an Interlynk account. Links last 24 hours and renew automatically when clicked after expiry, reducing the account barrier while retaining a defined access window. Integrations named in the getting-started guide include GitHub, GitLab, Jira, and Slack, and teams can set up SSO. A GraphQL API supports integrations, data retrieval and ingestion, and workflow automation.

The Community Tier can send policy-failure and new-vulnerability alerts through Slack, Microsoft Teams, webhooks, or email. Interlynk also offers free Apache-2.0-licensed CLI tools for SBOM work, a useful option for teams that want open-source tooling alongside the cloud platform.

Pricing

Community Tier — free. It is forever free, with no per-seat fees and no per-SBOM metering. API access and alerts are included, alongside the platform's stated vulnerability analysis, license analysis, policy enforcement, SBOM exchange, and release monitoring capabilities. That makes it a low-cost way to establish ongoing SBOM workflows without seat or inventory charges. No paid plan pricing is available to compare, so organizations evaluating broader needs should confirm the plan fit directly before committing to a rollout.

Platforms

Interlynk is available on web, Linux, macOS, Windows, and through an API. Its deployment model is cloud, which suits teams comfortable managing SBOM workflows through a hosted service but rules it out for requirements that mandate self-hosting.

Who it's for

Interlynk targets security, engineering, and compliance teams, including regulated organizations in medical devices, industrial and energy, and financial services. It says it supports teams shipping under FDA 524B, EU CRA, NIS2, DORA, and PCI DSS 4.0. The combination of supplier intake, release monitoring, and vulnerability context is particularly relevant when teams must manage component risk across both internal builds and external software.

Teams using IAR, GCC, or CMake for embedded C/C++ firmware have a specific supported generation path. Those on other embedded toolchains, or organizations that require self-hosting, should look elsewhere or verify fit before adopting it.

Pros and cons

• Pros: Lifecycle coverage spans SBOM creation, intake, enrichment, monitoring, and sharing, rather than stopping at inventory.
• Pros: Supplier links accept CycloneDX and SPDX without requiring suppliers to hold accounts, easing external document collection.
• Pros: The Community Tier has no per-seat or per-SBOM fees, and includes API access and alerts.
• Cons: Cloud deployment is the only stated model, so self-hosted requirements are a mismatch.
• Cons: Embedded generation is specifically described for IAR, GCC, and CMake; teams using other build systems lack a stated compatibility path.
• Cons: The Community Tier's free terms are clear, but there is no paid-plan pricing to help larger teams budget an expansion.

Alternatives

For a broader comparison, see SBOM Management Software.

Sonatype Nexus Repository is worth considering for teams that want a Community Edition with CI/CD integration and an external PostgreSQL option. sbomify may suit a small team whose needs fit its Community plan's one product, five components, unlimited SBOMs and compliance documents, public documents only, and single-user limit.

Ortelius offers a free plan capped at five components with unlimited users and endpoint tracking, making it an option for teams whose component count fits that ceiling. CAST SBOM Manager is a free-download alternative for Linux and Windows.

Exodos Labs may fit a single-user workflow with unlimited inventories and one API key on its Community plan. FOSSA is another freemium option, with its free plan capped at five projects and ten contributing developers. ReARM is a self-hosted alternative with a free single-organization community edition for core SBOM/XBOM storage and retrieval. TRUSCA is another free option, with no per-seat licensing and self-hosted deployment.

Verdict

Interlynk is a strong choice for regulated-software teams that need an ongoing SBOM process spanning component risk, supplier submissions, and releases, especially if they can use its cloud service and supported integrations. Its unmetered free Community Tier makes it practical to start without seat or SBOM charges. Look elsewhere if self-hosting is essential or your embedded build system falls outside IAR, GCC, and CMake.
