Isolating suspicious email links is described. An email security service receives an email that includes a link that refers to an external resource. A first suspicious link determination is performed to determine whether the link is suspicious. If the link is suspicious, the link is rewritten to refer to the email security and the email is delivered to the recipient. A request from a client device is received responsive to the link being opened. A second suspicious link determination is performed to determine whether the link is suspicious. If the link is suspicious, an interstitial page is transmitted to the client device that includes an option that, when selected, causes the first link to be opened in a remote browser isolation session.

Isolating suspicious links in email messages

An email verification system is described. The email verification system stores names and associated email addresses. An email is received that has a sender name and a sender email address. If the email verification system determines that the sender name matches a stored name but the sender email address does not match with an email address associated with the stored name, the email is prevented from being transmitted to its recipient unless the email is verified as being legitimate. The email verification system transmits a request to verify the email via a configured verification method. If a response is received that verifies the email as legitimate, the email is delivered; otherwise the email is blocked.
