Keep Exchange, Lose the Server

Protección contra spam y antivirus para correo electrónico

Los correos electrónicos de spam exponen sus sistemas a malware y ataques de phishing, además de ser una distracción muy costosa para los empleados.

Rackspace estima que más del 90% de todo el tráfico de correo electrónico es spam, aunque la mayoría de estos mensajes no llegan a la bandeja de entrada. Las empresas pierden millones de dólares en productividad y gastos adicionales de infraestructura debido al spam. Para empeorar las cosas, cada vez se hacen más fraudes de phishing por correo electrónico para extraer información confidencial y valiosa de las empresas, y para engañar a las personas y lograr que transfieran dinero a los criminales. El spam y las estafas de phishing por correo electrónico son una amenaza que evoluciona constantemente. Para defenderse, debe anticiparse a ellas.

Spam and Virus Protection

Spam and virus filtering is handled in two stages: blocked email, and filtered email. Rackspace ensures you will never see those messages in your mailbox first by blocking. Any spam messages that cannot be blocked is detected by email filtering, which is used to identify spam and send directly to your spam folder. 

Email Blocking

Out anti-spam and anti-virus solutions use many industry best practice techniques to block email from known, nefarious sources. The email blocking process covers everything from compromised servers to ‘spam cannon’ services which send email spam across the internet. These blocking techniques include IP blocking lists provided by reputable email industry services and by blocking emails with known attachment types used to exploit peoples’ computers and devices.

Email Filtering

If mail circumvents our blocked email checks, advanced content filtering is applied to further detect spam. The content filtering process combines various techniques which analyze email structure and content, and create beacons that identify spam patterns in email. These beacons are integrated with leading email industry sources to collectively report spam, phishing, and viruses. This process results in an extremely effective spam detection and removal system that continually adapts to the every-changing sophistication of spammers.
