The transmission of confidential information via electronic mail presents a complex security challenge. Electronic mail, in its standard configuration, often lacks the robust safeguards necessary to protect against interception, alteration, or unauthorized access. For instance, transmitting financial records, medical histories, or proprietary business strategies through regular email channels introduces a significant risk of compromise.
The importance of secure data handling stems from legal, ethical, and business continuity perspectives. Data breaches can result in severe financial penalties, reputational damage, and loss of customer trust. Historically, reliance on unencrypted email has led to numerous high-profile security incidents, prompting the development and adoption of more secure communication methods.
