What is E-mail Security?

E-mail security encompasses a range of techniques and technologies used to protect email accounts and communications from unauthorized access, loss, or compromise. Common methods include encryption (e.g., S/MIME, PGP) to protect the confidentiality of message content, anti-spam filters to block unwanted or malicious emails, anti-phishing measures to detect and prevent fraudulent attempts to obtain sensitive information, and malware scanning to identify and remove malicious attachments or links. E-mail security is crucial for protecting personal and business data, maintaining privacy, and preventing financial losses.
