Proofpoint evaluated as a Leader based on Completeness of Vision and Ability to Execute  

SUNNYVALE, Calif. – December 1, 2025 – Proofpoint, Inc., a leading cybersecurity and compliance company, today announced it has been named a Leader in the 2025 Gartner Magic Quadrant for Email Security for the second consecutive year. Previous to 2024, the Gartner Magic Quadrant for Secure Email Gateways was last published in 2015, wherein Proofpoint was recognised as a Leader seven consecutive times.  

Gartner evaluated 14 vendors for its 2025 report and recognised Proofpoint as a Leader for its Ability to Execute and Completeness of Vision, with Proofpoint highest in Execution. 

“We’re honoured to once again be recognised by Gartner as a Leader in Email Security,” said Tom Corn, group vice president and general manager of Collaboration Security at Proofpoint. “We’ve redefined what email security means for the modern enterprise, uniting deep threat intelligence, adaptive controls, and human insight to stop attacks before they become compromises. We believe this recognition reflects our relentless focus on protecting people wherever and however they work and our commitment to delivering the most advanced, integrated defence against today’s most sophisticated threats.” 

While 67% of CISOs say their cybersecurity culture is strong, a striking 76% believe their organisation is at risk of a material cyberattack in the next 12 months, according to Proofpoint's 2025 Voice of the CISO Report. Unsurprisingly, email fraud (37%) sits atop the list of growing CISO concerns. 

As email threats evolve, Proofpoint delivers comprehensive, human-centric protection against the full spectrum of modern attacks including email fraud, account takeover, QR code phishing, and even emerging threats targeting AI assistants. Proofpoint extends protection far beyond the inbox, securing communication across Teams, Slack, SharePoint, OneDrive, and more. 

Trusted by more than 2.7 million organisations worldwide, Proofpoint blocks 99.99% of all email attacks before they can cause harm. Whether deployed via API or gateway, Proofpoint’s advanced threat protection integrates seamlessly with Microsoft and Google environments to strengthen native defences and ensure employees stay productive while remaining secure. With unmatched detection, analyst efficiency, and a clear roadmap of ongoing innovation, Proofpoint continues to set the standard for modern email security in a rapidly changing threat landscape. 

Over the past 12 months, Proofpoint has introduced several technical integrations that unify email security with broader workspace protection such as: 

• Proofpoint's Core Email Protection API  offers organisations simplified deployment and administration without compromising on industry-leading detection efficacy. Customers value the ability to start with an API, with the option to move to pre-delivery protection in the future. 
• Messaging and Collaboration Protection  provides comprehensive defence against compromised and malicious URLs, regardless of how or where they’re delivered. Whether the link appears in a LinkedIn message, a personal Gmail tab, a Slack thread, or a QR code scanned on a mobile device, Proofpoint identifies the threat and blocks users from accessing malicious URLs.  Unlike other solutions which take an app-based integration approach, Proofpoint protects every click without requiring users to change how they work. 
• Threat Protection Workbench unifies data and actions into a single console—streamlining investigation and response based on customer requests for greater operational efficiency. AI Threat Summarisation auto-generates threat details, reducing analyst time spent on manual summaries. Native investigation is enhanced with screenshot and body access for faster user-reported email remediation. 

Proofpoint has also deepened ecosystem integrations with leading platforms such as Microsoft Sentinel, Crowdstrike, Palo Alto Network, and more. 

As of November 30, 2025, Proofpoint has an overall rating of 4.6 out of 5 in the Email Security Platforms market based on 1,507 reviews on Gartner Peer Insights™. Visit these 5 star reviews.
