One Bank's Success with Menlo Security for Email

This customer case study details the experience of a bank that implemented Menlo Security for Email to enhance its email gateway defenses. The document outlines a specific attack scenario where an exploit bypassed the bank's mail relay server due to the sender using a new IP address and email account. The exploit evaded the sandbox by utilizing a well-known evasion technique. However, Menlo's Positive Selection technology successfully neutralized the threat before it could reach the user's mailbox. The case study further describes subsequent developments, including a retroactive scan that identified a threat signature added in a recent update, which had been eliminated by Menlo Security without prior detection. The bank's Chief Information Security Officer expressed relief upon confirming that no damage had occurred and acknowledged the effectiveness of Menlo's solution, ultimately deciding against renewing a backup sandbox license due to the success of Menlo's technology.
