Metrics & reporting

Real-time insights and alerts for complete email oversight.

The Enterprise version of Stalwart includes a sophisticated dashboard designed to provide comprehensive visibility into your email server's performance and health. This feature-rich dashboard allows you to visualize a wide array of metrics, giving you real-time insights into server operations, email traffic, and system performance. With the ability to generate detailed reports, you can easily track trends, identify issues, and ensure optimal performance. Furthermore, the dashboard seamlessly integrates with monitoring systems like Prometheus, enabling you to leverage existing infrastructure for centralized monitoring and alerting.

Streamlined management with multi-tenant support.

Multi-tenancy is a powerful feature that enables a single email server to support multiple organizations or tenants, each with its own isolated domain and user management capabilities. In the Enterprise version of Stalwart, the multi-tenancy feature allows you to delegate administrative powers to specific accounts, empowering them to manage their own company's domains, accounts, and settings independently. This not only enhances operational efficiency but also ensures that each tenant maintains control over their environment. With this robust feature, Stalwart Enterprise Edition provides the scalability and flexibility needed to accommodate growing businesses and diverse organizational structures, all while maintaining high levels of security and performance.


Tailored branding for a cohesive experience.

The Enterprise version of Stalwart offers comprehensive branding support, allowing you to tailor the web-based admin and service portal to reflect your company's unique identity. With the ability to replace all logos and incorporate your company name in place of the product name, you can ensure a consistent brand experience for your users. This customization not only enhances brand recognition but also fosters a sense of ownership and professionalism. By aligning the email management interface with your corporate branding, you can create a cohesive and branded experience that reinforces your organization's image and values at every interaction.



Harness the power of AI for superior email security.

Stalwart Enterprise leverages AI technology to provide unparalleled email security and management. With AI-powered features, Stalwart Enterprise excels in accurately classifying spam, detecting sophisticated phishing attempts, and blocking various types of network attacks. This intelligent approach ensures that your email environment remains secure and reliable. Stalwart Enterprise comes equipped with a pre-trained large language model (LLM), offering robust out-of-the-box protection. Additionally, it supports integration with leading AI providers such as OpenAI, Anthropic, and other cutting-edge platforms, allowing you to enhance and customize your security measures.
