Interlynk

Interlynk is a cloud platform for managing software bills of materials (SBOMs) from creation through supplier intake and release monitoring. It is best suited to security, engineering, and compliance teams responsible for regulated software or devices. Its combination of risk tracking, supplier workflows, and an unmetered free tier makes it a practical option for sustained SBOM work.

Overview

Interlynk generates, ingests, enriches, monitors, and shares SBOMs, alongside open-source risk management and supplier monitoring. That end-to-end scope suits teams that need to track software components and changes over time rather than create a one-off inventory. It supports both SBOM standards, with vulnerability and license analysis, policy enforcement, SBOM exchange, and release monitoring.

The platform is cloud-based. Embedded teams can use lynkctl to generate SBOMs for C/C++ firmware built with IAR, GCC, or CMake. That is a useful fit for those toolchains, but teams using other embedded build systems should not assume equivalent support.

Key features

Component risk and policy

Interlynk matches components against NVD, GitHub Security Advisories, and OSV, with enrichment from EPSS, CISA KEV, and CWE. It monitors for newly disclosed vulnerabilities and supports VEX dispositions to help teams distinguish relevant findings from those that do not apply. Open-source risk coverage also includes license obligations and component maintenance status. This gives security and compliance teams several useful signals in one workflow, though teams still need to decide how those signals affect their own policies.

Supplier intake 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 need to onboard suppliers as platform users. GitHub, GitLab, Jira, and Slack integrations are named in the getting-started guide, and teams can set up SSO. A GraphQL API supports integrations, data retrieval and ingestion, and workflow automation.

Alerts and open-source tools

The Community Tier includes alerts for policy failures and new vulnerability disclosures through Slack, Microsoft Teams, webhooks, or email, as well as API access. Interlynk also offers a free, Apache-2.0-licensed toolkit with CLI tools for SBOM work, giving teams a way to use its open-source utilities without taking the full 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 vulnerability analysis, license analysis, policy enforcement, SBOM exchange, and release monitoring. That removes seat and SBOM-count charges as a concern for teams evaluating or maintaining an ongoing workflow. Interlynk has a freemium pricing model; no paid plan terms are included here, so readers who need a paid tier should expect custom pricing.

Platforms

Interlynk is available on web, Linux, macOS, and Windows, with API access. Its deployment model is cloud, which suits teams seeking a shared service rather than a self-hosted installation.

Who it's for

Interlynk is aimed at security, engineering, and compliance teams, including regulated organizations in medical devices, industrial and energy, and financial services. Its stated regulatory scope includes FDA 524B, EU CRA, NIS2, DORA, and PCI DSS 4.0. Teams that need to bring in suppliers, monitor vulnerabilities and licenses, and maintain SBOM workflows across releases have the clearest case for it.

Pros and cons

Pros

• Broad SBOM lifecycle coverage: generation, ingestion, enrichment, sharing, and release monitoring support ongoing rather than one-time management.
• Supplier submissions without accounts: secure links accept CycloneDX and SPDX files, lowering friction for external contributors.
• Free tier without seat or SBOM metering: API access and multiple alert channels are available without those usage charges.
• Embedded C/C++ generation: IAR, GCC, and CMake support addresses specific firmware build workflows.

Cons

• Cloud deployment only: organizations requiring a self-hosted platform will need another option.
• Embedded build support is bounded: the stated generator support covers IAR, GCC, and CMake, so other toolchains may not fit.
• No paid-tier terms to weigh: teams planning beyond the free tier will need custom pricing rather than a published price to compare.

Alternatives

For a broader shortlist, see SBOM Management Software. Consider Sonatype Nexus Repository if repository management and CI/CD integration are central, or sbomify if a free plan limited to one product, five components, public documents, and a single user suits the workflow. CAST SBOM Manager is another free-download option. Exodos Labs offers a free community plan with one user, one API key, and unlimited inventories. FOSSA may suit teams whose needs fit its free plan's caps of five projects, ten contributing developers, one release group, and five dependency levels for scans. Ortelius is a free option for teams tracking up to five components with unlimited users. OTNOS SBOM 360 offers a free plan with 50 monitored assets and one user. ReARM is worth considering for teams seeking a self-hosted community edition with core SBOM/XBOM storage and retrieval.

Verdict

Choose Interlynk if your security, engineering, or compliance team needs cloud-based SBOM management that connects component risk, supplier intake, and release monitoring, especially in a regulated setting. Its strongest practical advantage is a free tier that includes API access and alerts without per-seat or per-SBOM fees. Look elsewhere if you require self-hosting or depend on embedded build systems beyond IAR, GCC, and CMake.
