Domain Secure

Identify and stop more phishing and fraud, more quickly than any other solution.


The most comprehensive email fraud protection available on the market today.

With the industry’s most powerful email fraud protection technology, you can block phishing and fraud before it reaches your customers.

Your customers are continually bombarded by increasingly sophisticated, targeted phishing attacks, and it’s always challenging for security and fraud teams to identify such attacks before they have an impact. It has also been challenging to ensure a consistent email authentication strategy across all company domains to help block phishing attacks, as well as gathering email threat intelligence to facilitate the prosecution of attackers or the take-down of known phishing sites. Domain Secure provides security and fraud teams with the necessary tools to tackle these problems head-on.

With the world’s largest mailbox provider network, Return Path Domain Secure helps IT security teams to identify potentially suspicious mail streams as well as any legitimate email traffic that may be failing email authentication. With the most comprehensive set of email intelligence data, including email authentication and sender reputation data, as well as public and private aggregate and forensic level data streams, users of Domain Secure have complete visibility into legitimate email traffic and malicious traffic purporting to come from your domains. Email domains that are properly authenticating can be placed on the Return Path Registry, a private email registry allowing brand owners to set and enforce email blocking policies with major mailbox providers all over the world and block end-user targeted attacks.

Complete email visibility

Domain Secure helps marketers and security teams to gain intelligence around all outbound mail streams to ensure a consistent email policy. With the world’s largest mailbox provider data footprint, Return Path receives email intelligence from over two billion mailboxes worldwide, providing the broadest visibility into all of your email activity. In addition, Return Path can provide visibility into domains you don’t own or control; those unaffiliated domains that are also a major source of attacks on your brand by pretending to come from your company.

Block phishing attacks

In the unfortunate event your brand domains have been hijacked and are being used for to send spam and phishing messages, Domain Secure can help you proactively block phishing and spoofing activity. Active mail sending or parked domains can be placed on the Return Path Registry or we can help you to implement and manage your DMARC policy.
