Plesk

Plesk Obsidian 18.0.80 is here, and the focus of this release is AI-assisted server management. Plesk now supports MCP – Model Context Protocol, which makes it possible to manage a Plesk server through an AI agent. The AI Support Assistant, introduced in beta earlier this year, is now enabled by default on new servers.

Key Takeaway As a leading web server management platform, Plesk simplifies complex infrastructure management. It allows hosting providers to deliver secure, high-performance web environments. You must align your business with the appropriate Plesk edition to smoothly match your server’s administrative capabilities with your expanding client roster.

Key Takeaways Server-side optimizations can significantly improve Core Web Vitals. Establish a performance baseline before making changes. Caching and CDN delivery often provide the fastest wins. LiteSpeed is a valuable upgrade for high-traffic or resource-intensive sites. Better Core Web Vitals support stronger user experience, rankings, and conversions.

We once again reached out to the Plesk community for feedback on the features delivered in 2025 and the improvements our users want next. In total, 401 customers responded, representing hosting providers, agencies, developers, and IT professionals. Rather than just tallying satisfaction scores, our survey aimed to uncover how Plesk is helping you save time, strengthen security, and deliver better web experiences. Your responses give us valuable direction for the future.

Plesk Obsidian 18.0.79 is here, with security at the heart of this release. Following a comprehensive security audit, we addressed multiple vulnerabilities and introduced additional hardening improvements across the platform. Beyond security, this release expands the capabilities of the Plesk REST API, adds support for Microsoft SQL Server 2025, and delivers a wide range of stability, compatibility, and usability improvements for Linux and Windows servers.

Plesk Obsidian 18.0.78 introduces smarter SSL/TLS defaults that help secure newly deployed servers automatically and gives administrators more flexibility when using multi-factor authentication. This update also improves the GoAccess experience, and delivers a broad range of stability, compatibility, and security improvements across Linux and Windows.

summary Plesk comes with a mail server used to provide email services for mailboxes and mailing lists. After Plesk installation, the mail server is configured automatically using default settings. You may want to review them to make sure that they satisfy your needs. In this topic, you will learn how to configure a number of server-wide mail settings, such as relaying options or the maximum number of outgoing emails an individual mailbox can send per day.

The European Accessibility Act (EAA) establishes accessibility requirements for a wide range of digital products and services across the EU. After reviewing the act, we identified WCAG 2.1 AA as the technical standard that addresses its requirements and have been using it as our benchmark for improvements to the Plesk platform.

We are excited to announce the latest release of Plesk Obsidian: v18.0.77. This update brings one of the most significant accessibility improvements in recent Plesk history, introduces native ACME protocol support with the new ACME SSL extension, adds support for the GoAccess web statistics tool, and delivers a wide range of fixes, platform updates, and security improvements across Linux and Windows.

At Plesk, we’re committed to providing you with a fast, secure platform that evolves with today’s standards. That’s why, over the coming releases of Plesk Obsidian, we will begin transitioning away from legacy web statistics tools and introducing a more modern default. These updates simplify long‑term maintenance and ensure continued compatibility with the latest operating systems. Here’s what’s changing, and what it means for you.
