Proofpoint’s core insight is simple: people are the primary attack vector. Phishing, business email compromise, and social engineering cause more breaches than any technical vulnerability. The company’s entire platform is built around protecting the human layer.
The email security suite catches phishing, malware, and BEC attacks before they reach inboxes. Proofpoint’s detection engine analyzes content, sender reputation, behavioral signals, and URL/attachment payloads. It processes over 2.8 billion emails daily and blocks millions of threats every hour.
Beyond email, the platform covers security awareness training, cloud app security (for Microsoft 365 and Google Workspace), data loss prevention, and insider threat management. The DLP and ITM products use content inspection, user behavior analytics, and endpoint monitoring to prevent data leaks.
Thoma Bravo took Proofpoint private in 2021 for $12.3 billion, making it one of the largest cybersecurity acquisitions ever. The company serves over 75% of the Fortune 100 and is the market leader in email security by a wide margin. When it comes to protecting people from themselves, Proofpoint’s the benchmark.
