Description: An External Certification Authority (External CA) is a trusted entity that issues digital certificates used to verify the identity of organizations and individuals in the digital realm. Unlike internal certification authorities, which are managed by the organization itself, external CAs are independent and recognized by multiple platforms and browsers. This grants them a crucial role in the public key infrastructure (PKI), where they facilitate authentication and data encryption. External CAs operate under strict regulations and security standards, ensuring that the certificates issued are valid and trustworthy. Their primary function is to ensure that online communications, such as financial transactions and the exchange of sensitive information, are conducted securely. Additionally, external CAs help prevent fraud and cyberattacks by providing a means to verify the authenticity of websites and applications. In an increasingly digitalized world, trust in external CAs is essential to maintain the integrity and security of online interactions.
