For instance, this may include signing buildpacks and verifying their authenticity at runtime, signing apps from approved build pipelines to ensure only verified apps can be pushed to Cloud Foundry, and signing BOSH manifests and Operations Manager Tiles to control and verify the system state.<\/p>\n<p>We at Altoros are also strongly commited to both Cloud Foundry and blockchain.
