Gain 100% Protection
Message Angel incorporates more virus engines than any other email security solution. Multiple best-of-breed signature engines deliver guaranteed 100% protection against known viruses. Additional zero-hour and heuristic filters identify new and unknown viruses with minimal impact on scan time and service delivery.
Block Spam Efficiently
Message Angel focuses on connection management and integration of best-of-breed filters to block 98 percent of all spam with the lowest possible rate of false positives. Outbound spam protection locates and blocks infected machines from sending spam through the company network.
Protect Against Backscatter
Backscatter occurs when a spammer spoofs a legitimate email address to send an unsolicited message to large distribution lists. This causes the email server to flood an unsuspecting email address owner’s mailbox with hundreds or thousands of failed delivery messages. Webroot employs an advanced technique called Bounce Address Tag Validation (BATV) that provides robust protection for your business:
- Every sent message is marked with a timestamp and unique cryptographic signature that cannot be duplicated.
- Failed delivery messages that do not reference this signature are marked as spam and blocked from entering the user’s mailbox.
Stop Pornographic Images
The Message Angel Image Filter analyzes and blocks distasteful email attachments that can cause user distress and lead to corporate liability.
Neutralize Distributed Denial of Service (DDoS) Attacks
DDoS attacks on mail servers can disrupt a company’s email communications. When email traffic is routed through the Message Angel system, the attacks are neutralized before they reach your network.
Terminate Directory Harvest Attacks (DHA)
Spammers use DHAs in an attempt to locate valid email addresses by guessing permutations of common user names and attaching the domain name. The Message Angel service transparently consumes these emails instead of publicly rejecting them. Your organization is protected from DHA threats and divulgence of email addresses.
