The Retruster advantage

Traditional email security solutions route all emails through their servers. They have to decide “threat or not threat” (binary). If not a threat, email is released to user, who now trusts the email even if it’s phishing – resulting in false positives and not stopping sophisticated phishing emails. Retruster however uses a non-binary approach to empower users against the latest threats.
