The state of the email security market in 2025
Email remains the single most targeted channel for cyberattacks in 2025. According to Gartner and Cybersecurity Ventures, over 90% of data breaches still begin with a phishing email, while the global cost of email-borne cybercrime is projected to exceed $12 billion annually by 2026. Business Email Compromise (BEC) alone accounts for billions in annual losses, with the FBI reporting more than $50 billion in identified exposed losses worldwide between 2016 and 2024.
In the United States, organizations are particularly vulnerable as cloud adoption accelerates. Over 85% of American enterprises now use Microsoft 365 or Google Workspace, creating a massive attack surface. Phishing, ransomware delivery, malicious attachments, and increasingly sophisticated social engineering are the top threats. At the same time, the rise of AI-driven spear-phishing campaigns has pushed vendors to integrate machine learning, behavioral analysis, and automated remediation into their platforms.
The email security market itself is booming: IDC forecasts the sector will surpass $7.5 billion globally by 2025, with the US as its largest segment. Companies are prioritizing providers that offer not only spam and malware protection, but also account takeover prevention, data loss prevention, compliance tools, encryption, and user training.
In this context, our 2025 palmarès identifies the top players in the US market, based on real user feedback, ratings, and comparative analyses across major peer platforms such as G2, Gartner Peer Insights, PeerSpot, TrustRadius, and Capterra. This ranking highlights both the strengths and weaknesses of each solution, helping IT leaders choose the best fit for their environment.
Why this ranking matters
With dozens of vendors competing in the space, email security is no longer about simply filtering spam. The providers in this ranking are those that users consistently rate highest for threat detection accuracy, ease of deployment, integrations, support quality, and overall satisfaction.
The goal is not only to identify the strongest performers but also to show which solutions meet different organizational needs. For example, some platforms excel in enterprise-grade compliance and scalability, while others shine for SMB affordability and simplicity. By analyzing strengths and weaknesses side by side, this palmarès enables IT buyers, CISOs, and MSPs to benchmark providers based on real-world feedback.
Methodology of the 2025 palmarès
The ranking is based on a multi-factor methodology, including:
- Peer reviews and ratings: Data aggregated from G2, Gartner Peer Insights, PeerSpot, Capterra, and TrustRadius. Platforms with the highest number of verified reviews carried more weight.
- Feature performance: Analysis of advanced threat detection, sandboxing, account takeover prevention, phishing response, and integration with leading cloud ecosystems.
- Deployment and usability: Factors such as ease of setup, admin console clarity, and learning curve.
- Support and reliability: User feedback on vendor responsiveness, documentation, and customer service.
- Scalability and innovation: Cloud readiness, AI/ML capabilities, and ability to serve both SMBs and large enterprises.
