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.
🏢 Sizing, Licensing and Ordering Email Security & Anti-Phishing Gateway in and around Dighi Road
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.
🎯 Good Reasons to Move Off Your Current Setup in and around Dighi Road
Security proposals from unverified vendors often quote basic spam filters that lack cloud sandboxing and time-of-click URL inspection. We provide transparent, itemized proposals specifying the exact protected mailbox counts, sandboxing engine tiers, DMARC alignment scope, and SLA response terms. You know precisely what advanced threat detection capabilities you are purchasing.
You already have existing Microsoft 365, Google Workspace, or on-premise Microsoft Exchange servers that you want to protect without replacing your email platform. A Email Security & Anti-Phishing Gateway deploys cleanly via standard DNS MX record routing or direct cloud API connectors without requiring software installation on client workstations or mobile phones. We pre-stage your tenant, configure your policies, and execute the DNS cutover in the evening so your morning mail flow operates with zero downtime.
Strict DMARC, DKIM and SPF area Spoofing Defense in Kolkata
An architectural and engineering consultancy near Dighi Road suffered a credential-harvesting incident when a designer entered their corporate password into a fake Microsoft 365 login page linked from an email. We enabled Time-of-Click URL rewriting across all mail policies. When another phishing link arrived the following week, the gateway evaluated the destination URL at the moment of click, detected the newly launched credential-theft form, and blocked access immediately.
🛡️ WHAT WE DOCUMENT AND HAND OVER
Our Approach to Mail Flow Migration, Testing and Safety
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:
▪Automated Cross-Mailbox Search and Purge (Post-Delivery Remediation)
▪Annual Email Security Maintenance Contracts (AMC) with Defined SLAs
▪Complete DMARC (p=reject), DKIM & SPF Public DNS Alignment
▪Exchange Online Transport Connector Lockdown & Relay Protection
*Disclaimer: DNS zone updates, Microsoft 365 transport rule tuning, and incident remediation are charged on a project or contract basis. Cloud security subscriptions continue through the manufacturer.*
💡 Engineering Fact: Automated quarantine summary digests allow users to inspect and release legitimate commercial newsletters independently without IT intervention.

—Outbound DLP rules with overly broad keyword filters can flag legitimate business proposals, requiring policy tuning during setup.
✓Zero delivery delay architecture inspects and forwards legitimate business communications in sub-second timeframes.
—Unlicensed Microsoft 365 mailboxes or unlinked personal webmail accounts cannot be protected by the enterprise gateway.
✓DMARC, DKIM, and SPF area alignment prevents external scammers from forging your company area name on the open web.
—DKIM selector key rotation requires coordinated public DNS updates to keep uninterrupted email authentication.
✓Time-of-Click URL rewriting inspects hyperlinks in real time when clicked, neutralizing delayed credential-harvesting portals.

Never lose the master documentation folder containing your tenant administrator logins, DMARC reporting mailbox credentials, and DNS selector keys delivered at project handover. We keep duplicate records on our service desk to help during mail flow emergencies, but your management team must retain master ownership.
Default Microsoft 365 or Google Workspace spam filters rely primarily on known threat signatures and basic reputation lists, frequently missing zero-day phishing and display name impersonation. A Email Security & Anti-Phishing Gateway utilizes behavioral AI heuristics, cloud sandboxing, and Time-of-Click URL inspection to intercept advanced social engineering attacks.
Legacy on-premise spam appliances require continuous hardware maintenance, consume local server room electrical power, and introduce delivery latency during morning traffic spikes. Cloud Email Security operates on high-availability cloud infrastructure with zero local hardware and sub-second mail delivery.
💡 Engineering Fact: DMARC p=reject enforcement instructs receiving mail servers worldwide to reject unauthorized emails forged in your company's name automatically.
🛠️ Executive Impersonation and BEC Rule Configuration

Frequently Asked Questions
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 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.
Q. 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.
Q. 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.
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.
💡 Engineering Fact: Two-factor authentication (2FA) on email security administrative portals prevents unauthorized actors from modifying mail transport rules.
