Email security that stops attacks before they arrive
Over 90 percent of all cyberattacks start with an email. A single click on a phishing email, a malicious attachment, or a manipulated QR code is enough to unleash ransomware, fraud, or data leakage. Conbool MailGuard protects exactly this attack vector: threats are detected and blocked in real time before they reach the inbox.
