Software Supply Chain Security

Application security focuses on defects in your code; software supply chain security adds upstream provenance, components, and suppliers across IT, OT, firmware, and open source.

Exiger’s approach gives transparency beyond CVE scanning, mapping who built your software, where it came from, and why it matters for risk and resilience.

Read why Exiger was deemed a Leader in the Omdia Market Radar: Firmware and Software Supply Chain Security (SSCS).

According to CISA, an SBOM is a “formal record containing the details and supply chain relationships of various components used in building software … An SBOM provides those who produce, purchase, and operate software with information that enhances their understanding of the supply chain, which enables multiple benefits, most notably the potential to track known and newly emerged vulnerabilities and risks.”

It’s important to remember: an SBOM is simply an ingredients list – it doesn’t include any risk analysis on its own. To gain value from an SBOM, you need the kind of analysis Exiger provides.

SBOMs are fast becoming mandatory via legislation in the U.S. and worldwide. Read more on why software supply chain security and transparency depend upon them.

Binary Composition Analysis (BCA) – creates SBOMs by inspecting the binary or executable software files for patterns. Conversely, Software (or Source Code) Composition Analysis (SCA) uses the original source code files to generate SBOMs.

So which SBOM should I use? That’s probably not the right question. Think of differently produced SBOMs like differently produced medical images. They each provide a different view into the contents of a package.

They each have pros and cons: SCA analysis provides early vulnerability detection, but it can suffer from incomplete dependency information, and it tends to generate more false positive results. It’s also only available if you have the source code, making it not an option for many legacy products or for asset owners who lack access to source code.

Binary Composition Analysis (BCA) offers an accurate reflection of the software’s contents in its entirety. It also occurs downstream of tampering opportunities so it can detect compromises introduced at a late stage. It can also generate SBOMs in the absence of source code. BCA, however, does require the significant expertise and file format intelligence provided by Exiger solutions.

If you can’t see the risk, you can’t manage it. With or without SBOMs, Exiger helps expose malware, FOCI issues, vulnerabilities, single committers, end-of-life and a host of other risks hidden in software.

Exiger surfaces leading indicators—single-maintainer risk, end-of-life/abandonment, provenance anomalies, and foreign-influence signals—to catch issues before a CVE exists.

We also track supplier responsiveness (time-to-remediation) and use high-precision component attribution to reduce false positives, so teams focus on fixes that materially cut blast radius.

Exiger has one of the industry’s largest libraries for binary file unpacking and analysis and we support formats across IT, OT and IoT environments, including:

Binary executable file formats such as MZDOS and ELFs
Installers such as VISE, UPX, MSI, CABs, INNO, and InstallShield
Archives such as ZIPs, GZ/Tarballs, Freeze, and CPIO
Operating Systems such as Windows, Linux, VxWorks, QNX, and other RTOS
Common IT file systems such as NTFS, FAT32, and EXT
Embedded file systems such as LittleFS, SquashFS, JFFS2
Backup images such as WIM, Acronis Files & Directories, Clonezilla/GPart
Programming language identification for BASH, C#, and C/C++ source files

Yes. We flag chain-of-custody anomalies and adversarial contributions by watching release metadata and contributor behavior at scale, then correlate those signals to specific packages and build artifacts.

We also map blast radius across your portfolio so responders know what to quarantine first—see our analysis of recent npm compromises for how this works in practice.

By enriching SBOMs with supplier and component context, Exiger flags license obligations and policy exceptions, then ties them to clear actions and governance workflows. This enables procurement, risk, and engineering to enforce enterprise policies consistently—without slowing delivery.

Learn more about this governance angle in the Supply Chain Product Assurance Playbook.

Yes. APIs stream software-supply-chain risk into the systems teams already use, trigger automated playbooks and tickets, and feed shared analytics environments—reducing swivel-chairing and MTTR. They also centralize evidence for EO 14028/NIST-aligned requirements and unify visibility across IT, OT, and firmware to cut audit friction.

Our customer-proven integrations, offering endpoints to generate/ingest SBOMs, apply exploitability context, and automate workflows.
