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.

What is Business Email Compromise (BEC) and how does the gateway stop fake invoice fraud?

Business Email Compromise occurs when an attacker impersonates a company director, partner, or trusted supplier (often using a lookalike area name with one altered letter) to trick an employee into transferring funds or changing bank account details. Email Security analyzes sender writing styles, area registration ages, and display names, automatically quarantining impersonation attempts before they reach accounts staff.

Why should we procure Email Security through Microtech Solutions instead of buying online?

Procuring through Microtech Solutions guarantees your email security is engineered by certified systems professionals. You receive full SPF/DKIM/DMARC alignment, Microsoft 365 connector lockdown, VIP impersonation rule tuning, cloud sandboxing verification, and ongoing local engineering support across Kolkata.

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.

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.

How does the gateway detect compromised internal employee accounts?

The gateway monitors outbound email traffic volume and behavioral patterns. If an employee's password is stolen and the account begins sending mass spam or phishing emails, the gateway detects the anomaly, blocks outgoing messages instantly, and alerts our desk to secure the account.

Can staff manage their own quarantined marketing emails without contacting IT?

Yes. delivers automated quarantine summary digests directly to user inboxes on a customizable schedule (e.g., 9:00 AM and 2:00 PM). Employees can preview blocked newsletters safely and release genuine commercial mail with a single click, keeping IT helpdesk tickets to a minimum.

What happens if our primary mail server or Microsoft 365 experiences an outage?

The cloud gateway provides email spooling and continuity. If your destination mail server is unreachable, the gateway queues incoming messages safely in the cloud for up to several days, delivering them automatically once your server comes back online without bouncing emails to senders.

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.

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.

Can we configure visual warning banners on external emails?

Yes. We configure customizable HTML warning banners injected into the top of external messages (e.g., 'CAUTION: External Sender'). This provides an immediate visual checkpoint for employees before clicking links or processing payment instructions.

What maintenance is required to keep our email security operating reliably?

Routine maintenance includes reviewing monthly DMARC aggregate XML reports, updating VIP impersonation tables, inspecting quarantine false-positive rates, verifying SPF lookup limits, and tuning DLP rules during scheduled maintenance windows.

How does the gateway handle encrypted, password-protected PDF attachments?

When an email arrives with a password-protected attachment, the gateway can prompt the recipient via automated email to provide the document password, allowing the cloud sandbox to decrypt and detonate the file safely before releasing it to the user.

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.

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.

Affordable Business Email Security Deployment in Dunlop

Email security on a brochure means nothing if the gateway introduces five-minute delivery delays during busy mornings or causes legitimate client quotations to bounce into spam. In our staging lab, we tune mail routing rules under live production traffic - calibrating greylisting thresholds, configuring trusted partner bypass lists, and structuring SPF, DKIM, and DMARC records without mail flow interruption. The configuration deployed at your premises near Dunlop operates easily in the cloud without slowing down a single legitimate conversation.

🗺️ Sizing, Licensing and Ordering Email Security & Anti-Phishing Gateway throughout Kolkata

Engineer updating DMARC and DKIM DNS records for an office email area in Kolkata

The external statutory compliance auditor asked for proof of email data loss prevention (DLP), executive impersonation controls, and historical quarantine logs, and nobody could produce a report from standard webmail. A Email Security & Anti-Phishing Gateway enforces automated DLP rules that detect outgoing PAN numbers, GSTIN details, bank accounts, or source code, blocking unauthorized leaks or encrypting sensitive outgoing messages automatically. Reports export directly from the central cloud console, turning an audit scramble into a simple demonstration.

Running email security without centralized threat remediation means that when a sophisticated phishing email reaches twenty employees, an IT administrator must manually log into each mailbox to delete the message. An enterprise Email Security & Anti-Phishing Gateway features automated post-delivery remediation (Search and Purge). The moment a threat is identified in a single mailbox, the system searches all corporate inboxes and claws back the malicious email across the entire company within seconds, preventing other staff from clicking.

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.

🛡️ LAB STAGING, MAIL FLOW TESTING AND ENGINEERING PRACTICE

Frequently Asked Questions

Q. Will switching our email security cause delivery delays or downtime for our office?

No. The gateway operates on high-speed global cloud infrastructure that inspects and forwards messages in sub-second timeframes. We pre-stage your cloud tenant, configure transport connectors, and execute the DNS MX cutover during an evening window, ensuring zero lost emails or communication downtime.

Q. How does Time-of-Click URL protection work if an employee clicks a link hours later?

Attackers frequently send emails containing links to clean web pages that pass initial gateway scans, and then redirect those links to credential-theft pages hours later. Time-of-Click rewrites all hyperlinks inside incoming emails. When an employee clicks the link later, the gateway evaluates the destination website in real time, blocking access instantly if the page has turned malicious.

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. Why should our business use an email security gateway instead of relying on built-in Microsoft 365 or Google Workspace spam filters?

Built-in spam filters rely primarily on static signature databases and basic reputation lists. They frequently miss targeted zero-day spear-phishing, lookalike area spoofing, and fake supplier invoices sent from clean webmail accounts. The Email Security & Anti-Phishing Gateway uses behavioral artificial intelligence, cloud sandboxing, and Time-of-Click URL analysis to inspect incoming messages in real time, blocking social engineering attacks that slip past native cloud filters.

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.

💡 Engineering Fact: Business Email Compromise (BEC) detection algorithms analyze linguistic patterns, display names, and area registration ages to block executive impersonation.
