Enterprise Email Security
Email Is the #1 Attack Vector. Defend It.
Phishing, business email compromise, data exfiltration, and insider threats all start in the inbox. IoT Secure delivers layered email security — combining archive and forensics, anti-phishing, encryption, and DLP — to protect your organization's most exposed communication channel.
The Threat Landscape
Modern Email Threats Have Evolved Beyond Spam Filters
AI-generated phishing is now indistinguishable from legitimate email.
The email threats of today look nothing like the Nigerian prince scams of the past. Generative AI has enabled attackers to create highly personalized, grammatically perfect phishing emails that reference specific projects, use the correct email signatures, and mimic writing styles of real colleagues — at scale, automatically.
Business Email Compromise (BEC) alone cost U.S. businesses over $3 billion in 2025. These attacks don't use malware at all — they rely entirely on social engineering and legitimate-looking email to redirect wire transfers, obtain credentials, and manipulate employees into unsafe actions. Traditional spam filters are completely ineffective against them.
Archive & Forensics
Preserve Every Email. Investigate Any Incident.
Immutable Email Archive
Every inbound and outbound email is captured and stored in a tamper-evident, searchable archive. Meet HIPAA, SOX, FINRA, and government records retention requirements without managing complex on-premise storage infrastructure.
Rapid Forensic Search
When a security incident, compliance audit, or legal hold requires email review, find any email instantly using full-text search, metadata filters, sender/recipient search, and date range queries — across years of archived email.
Litigation Hold
Place specific mailboxes or email threads under legal hold to preserve them from modification or deletion during litigation or regulatory investigation. Maintain chain-of-custody documentation for court admissibility.
Incident Investigation
Reconstruct the complete timeline of a phishing campaign, BEC attack, or insider threat incident by reviewing all relevant email communication with full headers, metadata, and attachment details.
Anti-Phishing
Stop Phishing Before It Reaches the Inbox
Advanced Threat Detection
Multi-layer analysis combining reputation filtering, link analysis, attachment sandboxing, and behavioral AI to detect phishing attempts that bypass conventional signature-based filters. Catch novel phishing campaigns on their first send.
BEC & Impersonation Detection
Identify emails impersonating executives, vendors, and trusted partners using display name spoofing, domain lookalike detection, and behavioral analysis. Flag suspicious requests for wire transfers, credential input, or sensitive data.
URL Rewriting & Sandboxing
Rewrite links in delivered emails to route through a safe-browsing proxy. When a user clicks a link, it's analyzed in real time against current threat intelligence before the destination loads — protecting against delayed detonation attacks.
Spear Phishing Protection
Detect targeted spear phishing attacks that use personalized content, legitimate compromised accounts, or DKIM/SPF-passing domains to bypass technical defenses. AI-powered analysis identifies contextual anomalies in highly targeted messages.
Email Encryption
Protect Sensitive Email in Transit and at Rest
Policy-Based Encryption
Automatically encrypt outbound email containing sensitive data — PII, PHI, financial information, or content matching custom patterns — without requiring users to manually select encryption. Consistent protection without user friction.
Transport Layer Security (TLS)
Enforce opportunistic and mandatory TLS encryption for email transmission to and from specific domains. Ensure that email to your most sensitive partners and customers is always transmitted over encrypted channels.
Recipient-Friendly Delivery
Encrypted emails are delivered through a secure web portal that recipients access without special software. No S/MIME certificate management, no PGP key exchange — encryption that actually gets used.
HIPAA & Compliance Encryption
Satisfy HIPAA's requirements for encrypting ePHI in email transmission. Generate encryption audit logs that demonstrate compliance for OCR audits, Joint Commission surveys, and cyber insurance reviews.
Email Data Loss Prevention
Stop Sensitive Data Leaving Through Email
Outbound Content Inspection
Inspect all outbound email for sensitive data patterns — credit card numbers, Social Security numbers, PHI identifiers, financial account data, and custom regular expressions matching organization-specific sensitive content.
Attachment DLP
Analyze email attachments including documents, spreadsheets, and compressed archives for sensitive content. Block or encrypt emails that attempt to send controlled data outside approved boundaries.
Insider Threat Detection
Identify behavioral patterns consistent with insider threats — unusually high email volume, forwarding to personal accounts, large attachment uploads to personal email providers, or contact with competitors.
DLP Policy Management
Define and enforce granular DLP policies by user, group, domain, content type, and recipient. Review quarantined emails, manage false positive workflows, and generate compliance reports for regulatory review.
Protect your most vulnerable communication channel.
