Email is one of the most popular tools used for personal and business communication in the modern era
However, email is insecure by design. When you send an email, that email is plaintext and stored on someone’s computer. There’s no guarantee that your message is protected in transit or at rest. You are trusting the administrator of that computer not to read through your email. Email security refers to the measures taken to protect the confidentiality, integrity, and availability of electronic mail messages and their transmission. This includes protecting against unauthorized access, use, disclosure, disruption, modification, or destruction of email communications.
Without the right security measures, email can easily serve as a gateway for cyber attacks. A single act of negligence can compromise the safety and security of the organization’s email system. Attackers can spoof domains to make it appear that their emails are from trusted contacts, they can distribute malware and spam via email channels, and they can use social engineering to trick users to make payments or log into websites that contain malicious content. This makes email security one of the most important measures organizations must have.
Email security is important for the following reasons:
- Confidentiality Email messages may contain sensitive information such as personal information, financial data, and confidential business information that must be protected from unauthorized access and disclosure.
- Integrity Email messages must be protected from unauthorized modification or alteration to ensure that the information they contain is accurate and reliable.
- Availability Email is a critical communication tool, and ensuring that email messages are available to authorized users is essential for business operations and personal communications.
- Compliance Many organizations are subject to regulations that require them to protect sensitive information, including email communications.
- Reputation A security breach can damage an organization’s reputation and lead to a loss of trust and customers.
Having strong email defenses and protection solutions in place allows organizations to prevent and mitigate the risk of email-related cyberattacks and wade off malware threats before they even reach users’ mailboxes. This article outlines the ten best email security services to help you minimize exposure to email security risk in your organization.
