Mailinblack Protect is an email security solution designed to protect organizations from spear phishing and targeted email attacks. The product uses a combination of heuristic and proprietary technologies to identify and block highly targeted spear phishing attempts before they reach recipients. The solution analyzes multiple indicators to detect spear phishing attacks, including SPF validation, typosquatting detection, emergency semantics, sensitive data-related language patterns, and deep learning algorithms. When a spear phishing attempt is identified, the email is automatically quarantined before reaching the intended recipient. Protect addresses various attack vectors including sender identity impersonation, malicious attachments, links to malicious websites, and fraudulent bank transfer requests such as president scams and fake transfer order scams. The solution aims to prevent consequences such as operational disruptions, disclosure of confidential information, financial losses, reputation damage, and employee digital stress. The product is part of Mailinblack's broader email protection suite that also includes anti-spam, anti-ransomware, anti-malware, and anti-phishing capabilities. Protect differentiates itself by focusing specifically on personalized, targeted attacks rather than mass phishing campaigns.
