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 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.

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 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 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.

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.

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.

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 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.

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.

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.

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.

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 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.

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: 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.

Five branch sales offices across Kolkata communicating with clients over separate area aliases represent a massive administrative headache if spam and phishing rules are managed loosely. With Cloud Email Security, every area, shared mailbox, and remote user is protected under a single centralized management console. If a phishing campaign targets your sales team, our central desk purges the malicious message from every company mailbox simultaneously with a single click. We handle the complete DNS alignment, policy tuning, and quarterly threat reporting across Kolkata.

🧭 Supply and Aftercare for Business Buyers at multi-branch offices

Technician testing an encrypted email sandbox quarantine rule on a client workstation near Dakshineshwar

An accounts clerk receives an email that looks identical to your primary supplier's invoice template, complete with authentic logos and matching project names, but carrying altered bank account details. A Email Security & Anti-Phishing Gateway sits between the open internet and your mail server, analyzing incoming headers, area registration dates, and linguistic patterns in real time. The gateway recognizes that the sender area was registered forty-eight hours ago and flags the message with an explicit red warning banner or routes it directly to quarantine. We size mailbox counts, configure DNS MX records, and deploy policy rules for offices in and around Dakshineshwar.

A senior manager clicked a tracking link inside a courier notification email, opening a fake login page that captured their Microsoft 365 password. Email Security utilizes Time-of-Click URL protection that rewrites every hyperlink inside incoming emails. When the user clicks the link thirty minutes later, the gateway inspects the target website in real time, identifies the newly launched credential-harvesting form, and blocks access before the browser can load the page. Businesses across Kolkata rely on this real-time web reputation defense to eliminate credential theft risks permanently.

🔑 Why Businesses Pick Email Security & Anti-Phishing Gateway when budgets are tight

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 Dakshineshwar with flexible scaling so your communications protection grows alongside your business.

Ask any business owner whose accounts department transferred funds against a fake invoice what caused the failure. The answer is almost always the same: the email came from a lookalike area name that slipped past basic spam filters and fooled an employee who was in a hurry. The Email Security & Anti-Phishing Gateway uses behavioral artificial intelligence to identify executive impersonation, area spoofing, and writing anomalies before the message reaches a desk. Businesses around Dakshineshwar invest in genuine email security once and eliminate catastrophic invoice fraud permanently.

Manufacturing Plants: Preventing Supplier Payment Redirection Fraud

Frequently Asked Questions

Q. 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.

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. 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.

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. 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.

🗺️ REGIONAL PROFILE & MAP

🚩 Landmarks and Routes Our Engineers Know around Dakshineshwar

📍 Dakshineshwar

Dakshineshwar in Kolkata is one of the most spiritually significant and high-traffic regions, thanks to the renowned Dakshineshwar Temple. Pilgrims, tourists, vendors, and locals move through the area from early morning till late night. Beyond the temple zone, the locality includes residential houses, market areas, small businesses, and developing housing complexes. With this constant movement, having a reliable security setup becomes important for homeowners and shop owners.

Email Security & Anti-Phishing Gateway helps by providing consistent monitoring of gates, alleyways, shopfronts, and building entrances, ensuring that residents always stay informed. The combination of older lanes, riverside routes, market clusters, and new housing projects requires flexible surveillance. Homes located near the market or temple side experience higher footfall, while interior lanes have limited direct visibility. Email Security & Anti-Phishing Gateway brings clarity to both environments by capturing wide-angle views and strong night-time footage.

This helps families track unknown visitors, delivery activity, or late-night movement. For local businesses, the system helps keep oversight during peak temple hours when customer traffic becomes unpredictable. As Dakshineshwar continues to evolve with improved connectivity, residential development, and increasing daily footfall, surveillance becomes a key part of maintaining safety. Email Security & Anti-Phishing Gateway supports long-term monitoring without requiring manual supervision.

Whether someone lives near the ghat area, manages a shop, or stays in quiet internal lanes, having a trusted system ensures their surroundings remain visible and secure at all times.
