- **Compliance**: Regulatory frameworks like GDPR, HIPAA, PCI DSS, and FIPS require encryption for data protection. - **Security Guarantees**: Commercial cryptographic libraries and tools provide assurances, warranties, and ongoing updates that open-source libraries might not. - **Customization and Integration**: Large organizations often need bespoke cryptographic solutions that align with their unique infrastructure, which open-source libraries may not easily accommodate. - **Support**: Commercial solutions come with technical support, which is critical for businesses running mission-critical systems that rely on cryptography for data protection. - **Trust**: Certificate Authorities (CAs) provide trust through digital certificates, which are integral to securing websites, emails, and software distribution.
