Stop EmailRansomwareBefore It Strikes.
91% of all ransomware attacks start with an email. Conbool MailGuard neutralizes malware payloads before they reach your network.
Email Ransomware Protection for Businesses: Detect and Block Threats
Email is the most common attack vector for ransomware. Conbool MailGuard combines antivirus with curated additional signatures, structural and macro analysis, and ransomware-specific heuristics to identify and block malicious attachments and links – before the message is even delivered.
The Ransomware Threat: How Attackers Strike via Email
Encryption Ransomware
Ransomware encrypts files and entire systems within minutes. A single infected email is enough to halt business operations and trigger massive ransom demands.
Email as Attack Vector #1
Malicious attachments, weaponized Office macros, and disguised download links in emails are the primary method ransomware uses to infiltrate corporate networks.
Double Extortion
Modern ransomware groups steal sensitive data before encryption and threaten to publish it – even with backups in place, the damage can be devastating.
Comprehensive Email Ransomware Protection
Conbool MailGuard deploys multiple layers of defense to reliably intercept ransomware before delivery.
Pre-Delivery Scanning
Every inbound email is analyzed before delivery. Suspicious messages containing potential ransomware payloads are blocked before they reach the inbox.
Deep Attachment Analysis
Attachments are unpacked recursively, decompressed and inspected for malicious macros, scripts and executables, regardless of file type and with a depth limit against archive bombs.
URL protection at click
Links in emails are rewritten and checked against Spamhaus DBL, zero-reputation domains and PhishTank at the time of click, before the browser opens the target page.
Multi-Engine Antivirus
ClamAV scans every attachment and URL against curated signature sources such as SaneSecurity, Porcupine and URLhaus. rspamd scoring and CDR add structural and macro analysis on top of signature detection.
Zero-Hour Alerts
Behavior-based detection identifies novel ransomware variants within minutes – even without an existing signature. Instant notifications keep your IT team informed.
Ransomware-Specific Heuristics
Specialized detection rules analyze typical ransomware patterns such as suspicious file extensions, encryption routines, and command-and-control communication.
Why Traditional Antivirus Fails Against Email Ransomware
Conventional antivirus solutions only detect known signatures. Email-borne ransomware deliberately leverages zero-day exploits and polymorphic payloads that evade signature-based scanners.
Signature-Based vs. Behavior-Based
Traditional AV scanners only detect malware with known signatures. Conbool MailGuard additionally strips macros and active content from Office and PDF files, stopping loaders for which no signature exists yet.
Multi-Engine vs. Single-Engine
A single signature set only catches what is already known. MailGuard combines ClamAV with curated additional signatures such as SaneSecurity, Porcupine and URLhaus, and adds rspamd scoring and CDR on top.
Pre-Delivery vs. Post-Delivery
Traditional endpoint solutions only act once the file is already on the device. Conbool blocks ransomware before it even reaches the inbox.
Real-Time Zero-Day Protection
New ransomware campaigns often spread within hours. Conbool MailGuard's zero-hour detection responds in minutes – not after the next signature update.
