Antispam, Antiphishing, Antivirus and Email Encryption

The key functional areas that the mail security module of the Astaro Security Gateway addresses are the ability to:

Stop Spam - Implement effective spam prevention to minimize productivity loss and security vulnerability.  Stop threats before they reach your mail servers.

Prevent Phishing - Block emails from criminals attempting to con your users and prevent unsuspecting users from clicking links to fraudulent websites.

Block Viruses - Achieve excellent detection rates for known and unknown malware.  All SMTP and POP3 traffic is inspected through two AV scanning engines.

Encrypt Emails - Use standard encryption methods to prevent unauthorised interception of emails.  Client software is not required, with the encryption process transparently handled at the gateway.

Today, more than 80% of all messages are spam related.  Phishing attacks are on the rise and email still spreads many virus and spyware infections. Email security is therefore a major business requirement for organizations of all sizes. Furthermore, as the majority of emails are sent unprotected, comparable to a traditional postcard, organizations are exposed to major risks including the loss of vital information or violating industry regulations when disclosing confidential or proprietary information.

The Astaro Security Gateway delivers a unified solution for all of these risks, combining email filtering and encryption in one powerful platform.  Some of the key features of the email security components include:
 

• Scanning of inbound and outbound POP3 and SMTP traffic

• Suspect emails can be marked, quarantined or deleted
• Pportal and daily reports about blocked emails for user self-service
