Our take

Developers rely on open source code and apps in their day to day work, but when the provenance of the code is unknown this creates potential weaknesses that cybercriminals can exploit. Chainguard exists to build security into the coding supply chain by making it possible for companies to enforce security policies based on auditable signatures baked into the code.

In the wake of huge cyber attacks, software supply chain security has been an area of major focus. However, most of this has surrounded the scanning and detection of threats. Chainguard's approach comes from the other end of the process, focusing on building security into the software itself.

Built by former engineers who are aware of developer workloads, Chainguard is designed to be easily installed and integrated into existing automation systems. The company has secured substantial funding, the latest of which will support more aggressive product and R&D spending as it looks to further boost sales.
