The companies started working together in 2005 when EarthLink joined the RSA FraudAction Blocking Network in order to enhance its phisher blocking tools and services further. With today's announcement, EarthLink has also joined the RSA FraudAction worldwide detection network, a move that the company says will augment RSA's ability to counter more attacks faster and provide end-users with greater protection against online threats such as phishing.

"Consumers live in an 'always on' world and most have a constant broadband Internet connection and are always on the lookout for threats that can compromise their computers," says Jonathan Young, EarthLink's VP of security software, subscription and services. "Similarly, EarthLink is always on the offensive to make sure consumers have the tools they need for a safe online experience. Working with RSA and deploying products like EarthLink's ScamBlocker are only a few examples of our commitment to provide all Internet users with features that keep them safe from online threats."

EarthLink has also been rolling out a city-wide WiFi infrastructure across the United States and has most recently been selected to build, own and operate Arlington County, Virginia's Wi-Fi broadband network.
