84% of energy sector ransomware starts with a phishing email. Colonial Pipeline. NHS London. Change Healthcare. Every major infrastructure attack of the last 5 years walked in through the inbox. MailShield doesn't just block — it detects attackers, responds in real-time, and proves what happened with immutable evidence.
Every major cyberattack of the last 5 years started the same way: a single email. Not zero-days. Not supply chain exploits. A phishing email that bypassed legacy filters because it was contextually perfect. MailShield's Detect → Respond → Prove pipeline catches what legacy security misses — and gives you court-admissible evidence of every attempt.
Every one of these attacks would have been detected, contained, or prevented by active email defense. Legacy filters failed. MailShield wouldn't.

A single phishing email led to a compromised VPN password. Result: 6-day US fuel shutdown, panic buying across the East Coast, and a $4.4M ransom paid. The email bypassed all existing security because it targeted a legacy account with no MFA.
Email-borne ransomware hit Synnovis, the pathology provider for 7 London hospitals. Surgeries cancelled. Blood tests delayed for weeks. Qilin ransomware gang gained initial access through a spear-phishing email to a staff member.
Phishing email compromised credentials for a Citrix remote access portal. 190 million Americans' health data exposed. Cost exceeded $2.5 billion. Pharmacies, hospitals, and insurers nationwide disrupted for months.
State-sponsored Chinese APT used spear-phishing to infiltrate US utilities, water systems, and communications infrastructure. Pre-positioned for disruption. FBI and CISA confirmed phishing as the primary initial access vector.
Iberian Peninsula power grid failure left millions without electricity. Investigation ongoing, but SCADA system compromise via suspected phishing-originated intrusion remains a leading hypothesis per ENISA preliminary analysis.
The warning that went unheeded. BlackEnergy malware, delivered via a spear-phishing email with a weaponized Excel attachment, gave attackers SCADA access to 3 power distribution companies. 230,000 people lost power. This was the first known cyberattack to take down a power grid — and it started with one email.
Legacy email security is passive — it blocks known threats and misses everything else. MailShield's pipeline detects attackers with honeypots, responds with active countermeasures, and proves everything with immutable evidence.
Enforces DMARC, DKIM, and SPF authentication on every inbound and outbound message. Detects sender impersonation, domain spoofing, and anomalous login patterns before they reach your inbox.
Deploys honeypot email addresses woven into your directory. When attackers probe your organization for targets, they hit the honeypots and immediately fingerprint themselves — IP, timing, tools, and TTPs.
Powered by the ViperX engine. When enabled, identified attackers receive counter-intelligence responses — corrupted data, tracking payloads, and forensic attribution chains. Full jurisdictional disclaimers required before activation.
Blockchain-backed evidence locker seals all threat data immutably. Real-time threat timeline, geo-mapping of attack origins, and one-click compliance exports for GDPR, HIPAA, and SOC 2.
Enter your email address. MailShield auto-detects your provider via MX record lookup and configures itself. Zero expertise required.
Beyond the 4 core layers, MailShield includes everything your email security stack needs.
AI-powered look-alike domain detection, display name spoofing, and executive impersonation alerts.
End-to-end encryption for sensitive communications. S/MIME and PGP support with automatic key management.
Prevent sensitive data from leaving your organization. Pattern matching for PII, credit cards, and custom data types.
Detects hijacked accounts via behavioral analysis. Automatic lockdown and step-up MFA on anomaly detection.
Immutable audit trail for all inbound and outbound email. Tamper-proof logs for compliance and legal discovery.
Monitors dark web forums for leaked credentials and exposed email addresses associated with your domain.
Full REST API for managed service providers. Multi-tenant management, white-label reports, and bulk account provisioning.
Legacy enterprise email security costs $20-50/user/month and still doesn't fight back. MailShield does.
