GateWall Mail Security is an on-premises, software-based secure email gateway (SEG) developed by Entensys (a cybersecurity vendor known for its UserGate network security solutions). It is designed to sit between an organization’s internal mail server and the public internet to protect corporate networks from spam, phishing, viruses, and data leaks.
The platform is built on a modular, fail-safe architecture and integrates with various legacy email environments like Microsoft Exchange and Lotus Domino. Core Features
Multi-Engine Antivirus Protection: The system scans messages using three separate integrated antivirus modules: Kaspersky, Panda, and Entensys’ own cloud-based Zero-Hour protection, allowing it to block malware before massive global outbreaks occur.
Cloud-Based Anti-Spam: Employs content analysis, heuristics, and cloud infrastructure to catch over 97% of spam while keeping false-positive rates exceptionally low.
Data Loss Prevention (DLP): Monitors outbound traffic to prevent the unauthorized transmission of confidential company data. It utilizes three parsing technologies to scan bodies, threads, and attachments:
Regular Expressions (Regexp): For identifying structured data patterns like credit cards or ID numbers.
Document Matching (Docmatch): To check text against pre-configured corporate templates or sensitive document patterns.
Lemmatizer: Advanced linguistic text analysis to evaluate words based on their base forms and meanings.
Message Archiving and Backup: Automatically backs up and archives emails to ensure business continuity, e-discovery, and compliance audit paths.
Account Monitoring: Tracks internal email behavior to identify and flag accounts that might be hijacked or sending bulk malicious traffic outward. Deployment and Integration
Deploying the software involves setting it up within the corporate intranet and adjusting your domain’s MX (Mail Exchanger) records so that all inbound and outbound traffic routes through the gateway first. It is widely compatible with any SMTP-compliant mail server, providing a centralized control panel for security engineers to review email traffic statistics and quarantined messages.
