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 across 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.
💡 The Case for Doing It Properly Once across Kolkata
Some businesses can afford to clean up an infected laptop; an active trading house, an export firm handling international payments, or a law practice handling confidential client files cannot afford a compromised email account. Email Security provides Continuous Compromised Account Detection, monitoring outgoing mail patterns and user login behaviors. If an employee's credentials are leaked, the gateway blocks outgoing spam campaigns instantly and alerts our desk to secure the account.
Managing email security across multiple domains used to require complex mail server scripting and individual rule tuning. Provides an intuitive web interface with pre-built policy templates for Microsoft 365 and Google Workspace. Inbound protection, outbound data loss prevention, and quarantine digest schedules configure from a single screen, leaving your mail flow clean and manageable.
Corporate Microsoft 365 Email Defense and Anti-Phishing across DSP Steel Plant Zone
A commercial legal practice with twenty-five staff in Kolkata needed to prevent confidential client contract drafts and tax filings from being accidentally emailed to unauthorized external recipients. We configured Outbound Data Loss Prevention (DLP) with automated policy encryption. Emails containing sensitive legal keywords or financial data are automatically routed through secure encrypted web portals, ensuring full statutory compliance.

Frequently Asked Questions
Q. What is Search and Purge (post-delivery remediation) during a phishing attack?
If a sophisticated phishing campaign bypasses initial defenses or if a previously clean link turns malicious after delivery, Search and Purge allows administrators to claw back and delete the malicious email across all corporate mailboxes simultaneously within seconds, preventing employees from opening the message.
Q. What is DMARC and why is strict enforcement (p=reject) so important for our area?
DMARC (area-based Message Authentication, Reporting, and Conformance) verifies that emails sent using your area name are authorized by your organization. Setting a strict p=reject policy instructs receiving mail servers worldwide to reject any unauthorized email forged in your company's name. This eliminates area spoofing, protects your brand reputation, and ensures your legitimate sales quotes land in customer inboxes.
Q. How do we prevent spammers from bypassing the gateway and emailing Microsoft 365 directly?
We lock down your Microsoft 365 Inbound Partner Connector using IP restriction rules. Exchange Online is configured to accept incoming mail exclusively from verified gateway IP ranges, rejecting any connection try that tries to bypass the security perimeter.
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. 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.
💡 Engineering Fact: Automated Search and Purge capabilities use API connections to claw back and delete malicious emails across all corporate inboxes in under thirty seconds.
