Multi-layer scanning from sender reputation to content — nothing slips through.
Advanced Threat Protection
Multi-layer scanning stops zero-day exploits, spear-phishing, and targeted attacks before reaching any inbox.
Anti-Spam Engine
Bayesian filtering combined with real-time blacklists eliminates over 99.9% of unwanted messages with minimal false positives.
Email Authentication
Full SPF, DKIM, and DMARC enforcement — stops domain spoofing and brand impersonation dead in its tracks.
Real-Time URL Scanning
Every link in every email is inspected at click time. Malicious URLs are rewritten and blocked before the user lands on them.
Global RBL Protection
Backed by the World's Most Trusted Blocklists
SMG checks every sender against multiple global Real-time Blackhole Lists (RBL) simultaneously — blocking known spam sources and malicious IPs before a single byte is processed.
Spam & Phishing
Spamhaus
The world's most authoritative blocklist. Tracks spam operations, phishing networks, and botnet C&C infrastructure globally.
Network Threats
DShield
SANS Internet Storm Center's threat intelligence — blocks IPs actively targeting networks with attacks and probes in real time.
Enterprise Grade
Barracuda
Enterprise-trusted reputation database covering spam senders, phishing domains, and compromised mail servers worldwide.
How it works: Every inbound connection is instantly checked against all RBL feeds simultaneously. If the sender IP or domain appears on any list, the connection is rejected at the gateway level — before the email is even accepted for scanning.
Dedicated Antivirus Engine
Premium Virus Protection for Every Attachment
SMG uses a dedicated, purpose-built antivirus engine for email — not a generic AV — specifically tuned to detect malicious attachments, macro exploits, and hidden payloads in every file type.
Multi-Engine Attachment Scanner
Every attachment — .exe, .pdf, .docx, .zip, .xlsx — is scanned by the dedicated engine before delivery. Infected files are stripped and quarantined automatically. Users are notified instantly.
