Shield your networks with 100% effective virus blocking, backed by automated virus definition updates, and an unrivalled virus quarantine system. Tailored to small and medium-sized businesses, Meridius 500 takes the guesswork out of safeguarding your networks, offering powerful protection without risk to privacy, mail flow, or network resources.

Protect your network perimeter and block spam before it reaches your mail servers with a Meridius 500 Email Security Gateway™. Unlike the older, easily compromised Bayesian or heuristic text filter methods, Meridius 500 employs a newer and more aggressive eight-level Recurrent Pattern Detection™ (RPD™) spam engine. RPD works in real time to detect and classify recurrent patterns common to spam outbreaks, foiling spammers before they get a foot inside your network door.

 

Defend your mail relays with a mail relay policy, a set of Meridius-enforced rules that detect and mitigate spam and more serious threats like “relay-hijacking” (or “open relay”) vulnerabilities. Meridius 500 supports three types of policy entries-source, sender, and recipient policies-enhancing the security and integrity of your organizational or private networks. Define new policy entries and update your existing policy entries at any time using the Java™-based Meridius Management Console™, intuitive client software. It simplifies the task of policy creation, deployment, activation, updating, and end-to-end management.

 

Accept and process only emails sent to valid email addresses, or part of a defined recipient list using the Meridius LDAP-enabled Recipient Validation tools. Use “whitelists” to accept desired emails, even if they are routine solicitations often resembling spam. Use Real-time Blackhole Lists (RBL) of IP addresses of known spam sources to “blacklist” any undesirable traffic, dropping the connection before anything gets through. Reject all known spam with Super Blocking, dramatically reducing the number of messages marked as spam, messages passed on to recipients, or messages quarantined by Meridius.

 

Specify a spam “threshold” value, enabling Meridius to mark, quarantine, or reject spam according to a spam level configuration in the Meridius Management Console. Go further with optional inbound and outbound anti-virus checking, including real-time reports listing the dropped virus-infected messages, active recipients, and all information archived into comprehensive logs for subsequent audit.

 

Secure access, optimal performance
Test and troubleshoot your email relay systems with comprehensive log files generated by the Meridius Management Console. View and download log data for your mail relay, manage the quarantine database, and view product reports (including real-time graphs) from any computer with Internet access. Offer secure remote access to privileged users to access the network mail relay, and enable Web-accessible quarantine accounts so users can manage their own spam-quarantined emails.

 

Meridius 500 includes an onboard DNS caching server for mail routing, and can perform DNS mail exchange record lookups for optimal performance. Meridius also acts as a secure bridge between your servers and Internet clients to guard sensitive email stores from breaches; the built-in firewall adds yet another layer of protection. Built from the ground up on BlueCat’s highly secure Linux OS appliance design, a Meridius 500 Email Security Gateway™ delivers unbeatable, real-time spam and virus detection that includes world-class technical support from the Client Care professionals of BlueCat Networks.
