In today’s rapidly evolving threat landscape, cybersecurity professionals face mounting challenges from increasingly sophisticated bad actors. Limited resources, a growing attack surface, and the need for efficient threat detection and response make security operations more complex than ever. Enter generative AI (GenAI). This transformative technology enhances operational efficiency, automates routine tasks and provides deeper insights into complex threats.
Proofpoint leads this innovation with a new GenAI powered feature in our Email Security solution. Threat summarization simplifies how teams analyze threats and accelerates their communication.
This blog post takes a closer look at how GenAI empowers security teams and reshapes cybersecurity operations. And it covers how the new threat summarization feature uses GenAI to make teams faster, smarter and more effective.
Empowering SOC teams with Threat Summarization
Threat summarization addresses the daily challenges of SOC analysts and incident response (IR) teams. This feature enables teams to:
- Save time by automating threat summaries and eliminating hours of manual analysis, which improves the mean time to respond (MTTR)—an important SOC KPI
- Simplify their communication by explaining incidents clearly, showing what happened, why threats were blocked and the potential risks
- Gain key insights by providing granular forensic details, message content and attribution for actionable intelligence
Analysts generate these summaries directly within the Proofpoint threat insight dashboard, boosting productivity by up to 25% for SOC, IR and cyber threat intelligence (CTI) teams. With this tool, teams can produce incident reports, executive briefings and internal updates faster—without sorting through massive amounts of data.
Threat summarization reflects a broader industry shift toward GenAI-driven SOC operations.
5 Ways GenAI is revolutionizing email security
As threat actors use AI to innovate, defensive cybersecurity tools like those from Proofpoint are evolving to meet these challenges. GenAI and large language models (LLMs) are revolutionizing email security and SOC operations. Here’s how.
1: Threat hunting is advanced
Threat actors constantly refine their tactics, techniques and procedures (TTPs), which makes threat hunting more challenging. GenAI enhances this critical process by enabling faster threat detection. It analyzes billions of enterprise email messages, URLs, attachments, news sites, social media and even the dark web to extract actionable intelligence.
SOC teams can prioritize incidents by focusing on the most critical threats based on severity and potential impact. Additionally, by automating repetitive tasks and reducing false positives, GenAI frees up resources for SOC teams to concentrate on complex threats.
2: Email security is strengthened
As email remains a prime attack vector, GenAI fortifies organizational defenses. It identifies sophisticated phishing campaigns and social engineering tactics more effectively. Analysts gain valuable context through summaries that highlight targeted individuals, malicious URLs and attack methods. Furthermore, GenAI accelerates incident response by automating threat analysis, allowing teams to mitigate email-based risks more quickly.
3: SOC operations are simplified
Alert fatigue and data overload often overwhelm SOC analysts. GenAI addresses this by providing clear insights into alerts. This reduces investigation times and enables faster decision-making. Analysts can also use natural language queries to ask detailed questions and receive actionable, straightforward answers. As a result, investigations are more efficient and intuitive.
4: Reporting and communication are enhanced
Fast, clear communication is critical in cybersecurity, and GenAI excels at this. It automates the creation of detailed reports that stakeholders can easily understand. Additionally, GenAI customizes alerts to align with specific business needs, ensuring that notifications are relevant and actionable.
5: Teams stay ahead of threats thanks to continuous learning
GenAI continuously learns and adapts to emerging threats, ensuring defenses remain strong. It provides real-time threat intelligence by analyzing new data to detect patterns and anomalies before they escalate. It also refines security policies by recommending or implementing updates to address new vulnerabilities and attack patterns.
Why Threat Summarization is a game changer
Threat summarization is a transformative solution designed to address one of the most time-intensive tasks that SOC teams face daily. Based on extensive customer research, Proofpoint identified threat summarization as a critical pain point for organizations. Automating this process provides immediate, tangible benefits. SOC analysts can shift their focus from routine data gathering to high-value activities like advanced investigations, strategic planning and proactive threat hunting.

Share Feedback buttons and field allow the user to comment on the quality of the summary.
This innovative feature streamlines the creation of detailed threat summaries, enabling security teams to work with greater precision and efficiency. Analysts can quickly access actionable insights, reducing time spent on repetitive tasks while improving accuracy and clarity of their findings. This not only boosts productivity, but it also empowers teams to respond decisively to emerging threats.
Proofpoint has a strong commitment to responsible use of AI, data privacy and security. As a result, no customer data is used to train the large language models (LLMs) powering the threat summarization feature, and customer information is never retained or mixed with other data during summarization. Security protections are enforced by the LLM provider to ensure data confidentiality.
