Email detonation is a cybersecurity technique used to analyze potentially malicious email attachments or links. When an email is flagged as suspicious, its contents are opened and executed in a secure, isolated virtual environment known as a sandbox. This process allows security systems to observe the behavior of files or links without risking the organization's network. If malicious activity is detected, such as attempts to download malware or exploit vulnerabilities, the email is blocked or quarantined. Email detonation helps organizations proactively detect and prevent advanced threats, including zero-day attacks, phishing, and ransomware, by analyzing threats in real time before they reach end users.
