Email Threat Simulator by Living Security tests secure email gateway solutions, including Office 365 and Google Workspace, by sending real-world attacks to a test inbox. It identifies attacks that bypass secure email gateways (SEGs) and other vulnerabilities, improving defenses and aiding in remediation. It includes simulations for malicious attachments, ransomware, advanced persistent threats (APTs), file format exploits, and client-side attacks. It integrates seamlessly with Outlook Web Access or O365 for email security testing and provides detailed reporting with suggestions on vulnerabilities and a company score on email defense capability. Automated scanning and continuous defense checks ensure ongoing security by automatically scanning email gateway tools with newly added attack vectors.
