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.

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.

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 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.

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.

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 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.

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.

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.

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 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.

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.

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.

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.

Multi-Tenant Email Security & Anti-Phishing Gateway Mail Routing & Quarantine in Bijoygarh

Festival rush weeks and financial year-end closing around Kolkata are when fraudulent bank mandate change requests peak. Scammers inject themselves into existing vendor email threads using stolen credentials, altering bank account numbers on PDF vouchers just as payment is scheduled.

We set up each mail gateway with custom financial warning banners, ensuring your finance team never transfers funds to a fraudster's account.

📍 Deployment, Migration and Handover across Kolkata

Overview of the centralized multi-tenant email security console showing cross-branch threat metrics

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 Bijoygarh, 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.

💡 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 Bijoygarh

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.

🛡️ HOW WE DEPLOY EMAIL SECURITY ON SITE

How We Build Anti-Phishing Policies and Connectors

Mailbox sizing is where most business projects go wrong. We ask how many active user inboxes you run, how many shared departmental addresses exist, what third-party services send mail in your name, and whether subsidiary domains require protection - then configure the licensing tier and DMARC enforcement plan that handles that workload with multi-year expansion headroom.

Here is the email security engineering work we take on, quoted transparently before we begin:

▪Self-Service User Quarantine Digest Scheduling & Configuration

▪Annual Email Security Maintenance Contracts (AMC) with Defined SLAs

▪Inbound Cloud MX Gateway & Microsoft 365 API Connector Deployment

▪Outbound Data Loss Prevention (DLP) & Financial Keyword Filtering
