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.
✅ Deployment, Migration and Handover anywhere in Kolkata
Your company uses Microsoft 365 or Google Workspace for corporate email and assumes built-in security catches modern threats. Native cloud filters rely heavily on static signature databases and frequently miss targeted zero-day spear-phishing campaigns and weaponized macro attachments. The Email Security & Anti-Phishing Gateway integrates natively via cloud MX routing or direct API connections, scanning attachments inside an isolated cloud sandbox where suspicious files are executed and observed before delivery. For an office near Nagerbazar, that means dangerous attachments are neutralized before an employee can open them.
Your outgoing quotation emails are landing in your clients' junk folders or bouncing entirely because third-party spammers are forging your area name on the open web. An enterprise Email Security & Anti-Phishing Gateway deployment includes complete SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (area-based Message Authentication) alignment. We configure your public DNS records, set up cryptographic area signatures, and set strict p=reject policies, ensuring that unauthorized mail sent in your name is rejected worldwide while legitimate business quotes land reliably in customer inboxes.
🧠 What Changes in the First Month with a growing team
Business leaders do not want to parse raw mail header logs; they want clear visibility into blocked phishing attempts, impersonation trends, and area reputation health. Management tools create clean visual dashboards that report threat volumes, targeted employee names, and quarantine summaries directly to your inbox. When auditors or insurance assessors request cybersecurity controls, you have verified reports ready to share.
Very few companies keep a fixed employee headcount over time. Start with thirty mailboxes today, and the same cloud architecture scales easily to protect additional domains, shared mailboxes, and hundreds of users simply by adjusting license quantities. We design each email security deployment near Nagerbazar with flexible scaling so your communications protection grows alongside your business.
Multi-area Email Routing and Centralized Threat Governance

💡 Common Failures and How We Fix Them after years of site visits
Set up automated quarantine digest emails delivered twice daily (typically at 9:00 AM and 2:00 PM). This allows staff to review and release genuine commercial newsletters independently without flooding your IT helpdesk with support tickets.
Consumer antivirus software on endpoints only scans attachments after they have been downloaded to the local hard drive. Detonates suspicious files inside an isolated cloud sandbox before the email is delivered to the user inbox.
Standard webmail interfaces lack automated post-delivery threat remediation, requiring administrators to delete phishing emails manually across every inbox. Search and Purge claws back malicious emails across all company inboxes simultaneously within seconds.
💡 Engineering Fact: Computer vision and Optical Character Recognition (OCR) engines extract and evaluate QR codes (Quishing) inside attached image files.

Frequently Asked Questions
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 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. 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. How are shared mailboxes and distribution lists licensed?
Licensing is calculated based on active human user mailboxes. Shared mailboxes (like info@, sales@, or accounts@) and distribution lists that do not require dedicated user logins are protected under the security fabric without requiring duplicate individual licenses.
💡 Engineering Fact: Time-of-Click URL protection rewrites embedded hyperlinks inside incoming emails, evaluating the destination website in real time whenever an employee clicks.
