Email Security & Phishing Defense
Advanced threat protection that stops phishing, BEC fraud and malware before they reach the inbox — because 9 out of 10 breaches still start with an email.
What we deliver
Email remains the attack vector that works. Business Email Compromise doesn’t exploit software — it exploits trust: a convincing invoice, a spoofed director, a vendor’s hijacked thread. Signature-based filtering catches yesterday’s malware; it does not catch a fraudulent payment instruction written this morning.
Enrich deploys layered email defense: secure email gateways, AI-based impersonation and anomaly detection, link and attachment sandboxing, and DMARC/SPF/DKIM enforcement that stops others from spoofing your domain. We are a long-standing Barracuda partner and run these controls in front of Microsoft 365 estates daily — including our own.
For regulated organizations, the same stack produces the evidence trail: quarantine records, incident timelines and spoofing reports that CERT-In disclosures and audits ask for.
What's included
Advanced Threat Protection
Sandboxing of links and attachments — unknown payloads detonate in isolation, not on an employee’s laptop.
Phishing & Impersonation Defense
AI-based detection of spoofed senders, look-alike domains and executive impersonation — the attacks that carry no malware at all.
BEC & Account Takeover Protection
Behavioral analysis of mailbox activity and payment-instruction anomalies; compromised internal accounts get caught, not just external senders.
Secure Email Gateway
Policy-enforced inbound/outbound filtering, encryption and data-loss prevention at the mail boundary.
Domain Protection (DMARC/SPF/DKIM)
Correctly enforced email authentication so criminals can’t send mail as your domain — protecting your customers and your brand.
Incident Response & Forensics
Post-delivery remediation: malicious mail clawed back from inboxes, blast radius mapped, disclosure evidence assembled.
From assessment to operations
Assess
Mail-flow architecture review, spoofing exposure check (is your domain enforcing DMARC?), and a phishing-resilience baseline.
Design
Gateway and API-based protection layered onto your Microsoft 365 or hybrid mail estate — no rip-and-replace.
Deploy
Staged enforcement with live mail-flow verification at every step. Mail delivery is sacred; we treat it that way.
Operate
Continuous tuning, user-reported phish triage, quarterly spoofing and awareness reporting.

Common questions
We use Microsoft 365 — isn’t its built-in filtering enough?
+
Microsoft’s baseline filtering is competent against commodity spam and known malware. Where it consistently struggles is targeted impersonation, BEC and payment fraud — attacks with no malicious payload to scan. Layered protection adds behavioral and impersonation analysis in front of (or via API inside) Microsoft 365. That’s the configuration we run for our own mail.
What is BEC and why do standard filters miss it?
+
Business Email Compromise is plain-text social engineering: an email that looks like it’s from your CEO or a known vendor, asking finance to change bank details. There’s no link and no attachment — nothing for a signature engine to flag. Detection needs sender-behavior modeling, look-alike-domain analysis and payment-anomaly signals, which is exactly what the impersonation-defense layer does.
Will adding a gateway disrupt our mail flow?
+
No — deployment is staged: we run in monitoring mode first, verify clean mail flows untouched, then enable enforcement policy by policy. Mail continuity is verified at every step, and rollback is a DNS change away.
Can you fix our domain being spoofed to attack our customers?
+
Yes — that’s DMARC enforcement. Most Indian enterprises publish SPF but never move DMARC past monitoring, which means spoofed mail still delivers. We take domains to p=reject safely: inventory every legitimate sender, fix their authentication, then enforce. Your domain stops being usable as a weapon.
