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 in and around Pujali
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 Pujali, 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.
🎯 Good Reasons to Move Off Your Current Setup in and around Pujali
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 Pujali 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.

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: Time-stamped forensic mail logs record message IDs, envelope senders, TLS encryption cipher levels, and quarantine reasons for ISO compliance audits.
Frequently Asked Questions
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. 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. 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. 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.
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.
💡 Engineering Fact: Two-factor authentication (2FA) on email security administrative portals prevents unauthorized actors from modifying mail transport rules.
