Threat actors target Symantec Email Security

Symantec Email Security.cloud has not kept pace with innovation in email threat detection. Customers report stagnant product development, limited AI investment, and gaps in protection against advanced threats, such as business email compromise (BEC) and credential phishing.

Proofpoint has delivered breakthrough innovations in Nexus AI, combining:

• Machine learning models that classify billions of daily messages
• Language models that understand intent and spot social engineering
• Relationship graphs that track trusted sender–recipient patterns
• Optical character recognition (OCR) and content analysis to uncover QR code phishing, image-based lures and malicious attachments
• Global threat intelligence curated by our researchers

This multilayered stack delivers 99.99% detection efficacy with one of the lowest false positive rates in the industry.

Symantec workflows force analysts into manual triage, repetitive searches and limited reporting capabilities. User-reported emails often pile up in inboxes, requiring hours of manual investigation, and critical alerts are buried in noise—slowing time to detect and respond.

Proofpoint streamlines the analyst experience, reducing typical investigation click paths from 12+ down to just 3–4. With automated abuse mailbox handling, user-reported messages are automatically correlated with known threats, cutting remediation times by up to 70%. This gives you enriched context, prioritized insights and timelines that turn hours of work into minutes.

Symantec email security platform has declined in both customer trust and industry recognition. The product is absent from the 2024 Gartner Magic Quadrant for Email Security Platforms and the 2025 Forrester Wave for Email, Messaging, and Collaboration Security Solutions, reflecting reduced investment and innovation under Broadcom. Customers increasingly cite detection misses, service outages and poor support experiences as reasons for leaving.

Proofpoint is trusted by 83% of the Fortune 100 and more than 2.7 million organizations worldwide. Recognized by analysts for leadership and innovation, Proofpoint continues to invest heavily in AI, automation and analyst efficiency. This means you gain a partner with a clear roadmap and a proven track record of keeping pace with an ever-changing threat landscape.
