With 94% of email classified as junk, sorting good email from bad can be an administrative nightmare. By adding SonicWall™ Comprehensive Anti-Spam Service (CASS) to a SonicWall firewall, your business can remove junk email at the gateway and quickly ensure the delivery of only good email to your email server. With one-click activation, businesses with up to 250 users can easily stop spam before it enters the network.
It takes only minutes to configure CASS, and only one click to activate. Once activated, CASS immediately starts to block spam, phishing and virus-laden email. MX Record redirection is not needed.
Junk email is blocked and rejected at the gateway, before it enters your network.
Smaller businesses can leverage their existing investment in a SonicWall firewall to quickly ensure the delivery of only good email with CASS. Larger enterprises can layer their anti-spam protection by placing CASS in front of a SonicWall Email Security solution.
CASS offers 98% effectiveness against spam, dropping 80% of spam at the gateway, while utilizing advanced anti-spam techniques like Adversarial Bayesian filtering on remaining email.
The SonicWall firewall becomes your single point of management for all traffic going through the device, including spam management.
Stop attacks with over 99% effectiveness
Block spam, phishing, zombie and virus attacks with over 99% effectiveness and ensure delivery of good email using proven, patented1 techniques like reputation checks, directory harvest attack (DHA) protection, Denial of Service (DoS) protection, adversarial Bayesian filtering, image analysis and sender validation.
Real-time threat information
Get the most up-to-date protection against new email attacks with real-time information from the SonicWall Global Response Intelligent Defense (GRID) Network and GRID Anti-Virus™ signatures.
Administrators can deploy or delete Junk Boxes for users to store junk messages. With optional Junk Box Summary emails, users can view text emails designated as junk, with IT retaining control over delivery of summaries and settings.
Flexible LDAP integration enables easy and secure user management with support for multiple LDAP servers.
Advanced Reputation Management (ARM)
SonicWall Advanced Reputation Management utilizes Sender IP Reputation to drop junk email at the connection level, before it enters the network. Real-time reputation scores from the SonicWall GRID Network identify and block junk email from spammers.
Unique anti-phishing protection
Phishing emails are placed in a designated Phishing Folder, reducing the risk of having financial, personal or proprietary information lost through an email-based phishing attack.
Allow and Block lists
With Allow and Block lists, administrators can easily block or allow emails from specific people, company, and addresses on both a global and per-user basis.
How It Works
1. Email arrives at the SonicWall network security appliance.
2. Junk email is rejected based on Sender IP reputation and additional characteristics.
3. Remaining email is evaluated to determine if it is good or junk.
4. Good email is sent to the email server.
5. Optionally, junk email can be placed in user junk boxes on the email server.
