### [Raven Email Threat Detection](https://www.g2.com/products/raven-email-threat-detection/reviews)

Raven Email Threat Detection is a cloud-native email security software for Google Workspace and Microsoft 365. Built using large language models (LLMs), Raven goes beyond traditional secure email gateways (SEGs) by detecting advanced, identity-based threats like phishing, business email compromise (BEC), vendor impersonation, and thread hijacking — even when standard trust signals like SPF/DKIM/DMARC pass. Raven’s AI-native engine analyzes email content, sender-recipient context, behavioral baselines, and infrastructure signals to surface threats that legacy tools miss. It detects credential phishing, impersonation, and invoice fraud without relying on static rules or keyword matching, ensuring high detection efficacy with low false positives. What sets Raven apart is its built-in vendor risk detection engine — an industry-first capability. Raven automatically fingerprints vendor invoices, flags suspicious changes in bank account details, monitors email and web infrastructure for compromised third-party tools, and detects spoofed or unauthorized senders in conversation threads. This enables companies to stop supply chain attacks, which are increasingly the root cause of financial and reputational losses. Deployed through secure APIs, Raven integrates natively into Microsoft 365 and Google Workspace in under 10 minutes — with no MX record changes required. Raven can complement or replace traditional tools like Proofpoint, Mimecast, Cisco IronPort, or Microsoft Defender, offering post-delivery remediation capabilities such as inbox pullback, domain blocking, and RBAC-governed investigations. Raven is fully ISO 27001 and SOC 2 compliant, with support for privacy and compliance use cases across regulated industries including financial services, healthcare, manufacturing, and SaaS. Key use cases: Detect phishing and BEC attacks with LLM-powered email threat protection Stop vendor-origin threats using invoice fingerprinting and domain monitoring Identify lookalike domains, thread hijacks, and insider risks Enable real-time remediation and insights without disrupting mail flow Integrate with SIEMs and GRC platforms for centralized response Raven is ideal for security teams that need modern, AI-driven email protection that evolves with emerging attacker techniques — especially where email security software must balance contextual intelligence, low false positives, and fast deployment.

Intelligent email protection, sometimes called human-layer security, is a class of software solutions designed to prevent a company’s employees from sophisticated email-focused cyberattacks. These tools use machine learning to analyze historical records of email content, user behavior, and email-based threats, identifying risks and developing a baseline for user behavior. Intelligent email protection products filter incoming emails to detect and block potential phishing attacks, attachments containing malware, and links to potentially dangerous websites. They also filter outbound emails to detect accidental data leakage, data exfiltration, and the misuse of privileged data.

Companies use these solutions because all employees are susceptible to traditional phishing attacks, targeted spear-phishing attacks, malware, and other email-based threats. Employees can also pose a risk if they unknowingly share sensitive information in noncompliant ways. Additionally, every business is at risk for insider threats, and these products will detect abnormal activity involving sensitive data.

Some intelligent email protection tools fall into the same category as [secure email gateway](https://www.g2.com/categories/secure-email-gateway) and [cloud email security](https://www.g2.com/categories/cloud-email-security), which are also used to prevent phishing attacks and malicious emails from reaching employees. Those solutions, though, do not provide the scope of intelligent automation capabilities needed to identify anomalies and detect risky behaviors. Some overlap also exists with [email anti-spam](https://www.g2.com/categories/email-anti-spam) solutions, which have an even smaller scope of capabilities limited to blocking spam and phishing attacks.

To qualify for inclusion in the Intelligent Email Protection category, a product must:

- Filter incoming and outgoing emails
- Utilize machine learning to develop employee baseline behaviors
- Detect and block unauthorized outbound emails and incoming emails containing advanced persistent threats
