A Scalable, Redundant, Fault-Tolerant & Load Balanced Mesh of Clusters        

Geographically dispersed around the globe with a primary focus of reducing latency, the MailGuard network of mail filtering servers is a scalable, redundant, fault-tolerant and load balanced mesh of clusters.

Multiple Anti-Spam Engines for Protection Against Phishing, Spear Phishing, Ransomware and BEC                     

Dynamic anti-spam engines, including proactive heuristic filters, combined with ML and enhanced with generative AI, identify and stop incoming threats. Layers of email threat filters combine for advanced protection, performance and accuracy.

Superior catch rate with near zero false positives, with no special tuning or ongoing administration.

Comprehensive anti-spam reporting including individualized reports for employees (console), plus end-user spam quarantine release functionality.

Virus, Malware & Blended Threat Protection     

Integrated anti-spyware scanners specifically target malicious URLs embedded in messages with the MailGuard proprietary IP threat detection engines.

Our engines detect and unpack archive file types, identifying viruses recursively embedded within attachments. Once identified, we block dangerous file types by their content and MIME type, thus detecting mislabelled attachments.

Deep content analysis is undertaken of all email components to identify and quarantine messages containing potentially harmful code or URL links to known malicious websites.

Virus protection is applied to both incoming and outgoing email, supported with full virus and malware reporting

Take Action On Incoming Email Based On Pre-Defined Conditions    

Action can be taken on messages exceeding a specified size limit (eg. Reject or Quarantine) or messages from any blacklisted IP address and domain. Other reject categories such as country can be applied by contacting MailGuard support.

Control inbound messages based on the presence of restricted file types or inappropriate keywords. Implement policies by user or domain – or across the entire organization.

Provide visibility of the security of incoming email through comprehensive reporting and email notifications.

Manage email authentication and anti-spoofing through Sender ID and Sender Policy framework standards support.

Outbound Policy Enforcement and Compliance Management  

Automatically applies SPAM policy to outgoing messages, and enforces policies relating to outgoing message size, attachments, keywords or recipients.

This allows you to block inappropriate language in outgoing email, upholding corporate policies and ensuring messages comply with legal requirements.

Automatically add disclaimers based on individual, domain or company.

Facility to provide alerts based on outbound email content and attempted policy breaches.

Protect Against Denial of Service & Directory Harvesting Attacks

Detect and manage suspicious behaviour such as rapid concurrent connections from a single IP address or multiple emails sent to invalid email addresses.

When suspected Denial of Service or Directory Harvesting Attacks are detected, connection attempts from the offending SMTP server are rejected without impact to the customer.

Features File Fingerprint Technology To Manage Distribution of Confidential Files and IP

MailGuard quarantines any restricted file being sent by an unauthorized user and sends notifications to nominated email addresses.

Our platform provides the ability to use regular expressions (regex) to create powerful pattern matching rules.

Comprehensive Reporting and Message Classification

Access comprehensive security and email activity reporting, and 

schedule reports with email delivery options in a range of output formats including HTML and PDF.

Review bandwidth reports by sender, recipient, domain and file-type, plus analyze anti-spam performance by user via individualized reports.

View anti-spam/anti-virus performance, attempted policy breaches and identify potential mail abusers through security reports. Use this data to setup specific policies to output digests received directly.
