A fake email claiming to be from your managing director asking for an urgent RTGS bank transfer rarely carries a detectable virus attachment; it carries clean text sent from a lookalike area name with an extra letter. Basic antivirus scanners wave those messages straight through because there is no malware payload to trigger a signature. Email Security uses advanced natural language processing and sender identity verification to spot business email compromise (BEC) and executive impersonation in real time, tagging or dropping the message before an accounts clerk can act on it. At Microtech Solutions, we deploy this layer alongside strict DMARC enforcement so your company identity cannot be forged.
🗺️ From Quotation to Go-Live with throughout Kolkata
An aging on-premise spam filter hardware appliance sits in your rack, requiring manual firmware updates, clogging internet bandwidth, and delaying morning email deliveries by fifteen minutes. Migrating to an enterprise Email Security & Anti-Phishing Gateway transitions your email defense to high-availability cloud infrastructure with zero local hardware footprint. Inbound emails are scanned and delivered in milliseconds, spam is filtered before entering your local network, and administrative overhead is eliminated. We handle the complete DNS cutover over an evening so staff arrive to clean, fast inboxes on Monday.
Attackers are increasingly bypassing text-based email filters by embedding malicious phishing URLs inside graphic images and QR codes (Quishing) attached to PDF documents. A Email Security & Anti-Phishing Gateway utilizes Optical Character Recognition (OCR) and computer vision engines to extract QR codes and text from image attachments, analyzing the destination URLs against live global threat databases. Malicious QR codes designed to steal multi-factor authentication tokens are dropped at the gateway, keeping mobile users and desk staff in Kolkata protected.

Preventing Fake Supplier Invoices and Business Email Compromise (BEC)
A healthcare diagnostic laboratory network in Kolkata received frequent malicious emails with weaponized PDF attachments containing zero-day ransomware designed to lock patient records. We deployed Email Security & Anti-Phishing Gateway with cloud sandboxing. When an infected PDF arrived disguised as a medical equipment quote, the sandbox executed the file in an isolated cloud chamber, identified the background ransomware payload, and blocked delivery across all staff inboxes.

Frequently Asked Questions
Q. What is Quishing and how does the software detect QR code phishing attacks?
Quishing occurs when attackers embed malicious phishing links inside QR codes attached as images or PDF files to bypass text-based spam filters. Email Security uses computer vision and Optical Character Recognition (OCR) to extract QR codes from attached images, analyzing destination URLs against live threat databases and blocking credential-theft attempts.
Q. How does Outbound Data Loss Prevention (DLP) prevent confidential data leaks?
Outbound DLP inspects outgoing emails and attachments for sensitive data patterns like Indian PAN cards, Aadhaar numbers, GSTIN codes, and bank account numbers. If an employee attempts to email unencrypted confidential records, the gateway can block delivery, notify compliance managers, or automatically route the message through an encrypted web portal.
Q. What is cloud sandboxing and how does it handle suspicious PDF or Office attachments?
When an email arrives with an unknown attachment (such as a PDF invoice or Word document with macros), the gateway sends the file to an isolated cloud sandbox chamber. The file is executed and observed for suspicious behaviors like ransomware encryption or background script execution. If the file behaves safely, it is released to the user inbox within sixty seconds; if malicious, it is dropped.
Q. Who owns the email security tenant logins, DMARC keys, and policy documentation?
You do. At project sign-off, we hand over a complete documentation package containing your cloud tenant URLs, administrative credentials, 2048-bit DKIM selector keys, DMARC reporting mailbox logins, and transport connector maps. Your company retains full ownership.
Q. Can the gateway protect multiple subsidiary domains under one company account?
Yes. Multi-tenant architecture allows managing multiple corporate domains, subdomains, and subsidiary brands from a single web console, applying standardized security rules while maintaining area-specific routing.
💡 Engineering Fact: Greylisting anti-spam technology temporarily rejects initial incoming messages from unverified mail servers, dropping automated spam bots.
