Best Secure Email Gateway Software for Elastic Observability

Proofpoint's Email Protection solutions, available as either a cloud service or an on-premises installation, offer robust defense against both malware and non-malware threats, such as impersonation emails and business email compromise (BEC). Its fine-tuned email filtering effectively manages spam, bulk "graymail," and additional unwanted messages. Moreover, the system ensures uninterrupted email communication even during server outages. Recognized as the premier email gateway in the industry, Proofpoint captures a wide range of threats, including those that may elude other systems. Utilizing advanced machine learning through NexusAI, Email Protection efficiently categorizes different email types and identifies threats that lack malicious payloads, including impostor emails via its Advanced BEC Defense feature. Additionally, users can automatically tag potentially suspicious messages to enhance awareness and can quickly locate any email within seconds, ensuring a comprehensive approach to email security. This layered defense provides organizations with peace of mind while navigating the complexities of email communication.

Email continues to be the most vital communication medium for enterprises, yet this prominence also positions it as the primary threat vector, with the frequency and complexity of cyberattacks escalating. As organizations increasingly transition to cloud-based email services, such as Microsoft 365 and Google G-Suite, they are facing challenges in securing their email communications. The native security features provided by these platforms are often inadequate for defending against various threats, safeguarding critical information, and achieving compliance requirements. FortiMail, Fortinet’s secure email gateway solution, offers a thorough, multi-layered strategy for managing both incoming and outgoing email traffic effectively. Renowned for its reliability, Fortinet provides an extensive array of security solutions—including identity management, advanced threat protection, and security-driven networking—integrated within its Security Fabric, ensuring comprehensive protection for businesses. This robust offering allows organizations to confidently navigate the complex landscape of email security.
