Security in software is now a shared responsibility among all teams and users, as no single entity can guarantee trustworthiness. This is where Cloudsmith comes in, providing the ability to build trust within your own teams or with customers by allowing use of custom domain names for repositories. This matters because it enhances Identity and Brand Awareness, provides Security and Control, and offers Flexibility. By using a custom domain, you have control over implementing security features like DNSSEC and CAA, reducing typo-squatting, and can easily switch vendors without affecting build definitions, package manager configurations, and scripts, making it fully decoupled.
