Kinsta Integrates Patchstack to Automatically Protect All Hosted WordPress Sites
Managed WordPress host Kinsta now automatically shields all its hosted websites with Patchstack's application-layer vulnerability protection, blocking millions of exploitation attempts in its initial weeks.
Kinsta has announced a significant enhancement to its security offerings, now automatically integrating Patchstack's Vulnerability Protection into every WordPress site it hosts. This new feature, available at no additional cost to customers, provides a robust layer of defense against known vulnerabilities by blocking exploitation attempts at the application layer.
In the initial weeks following its deployment, Kinsta's Vulnerability Protection, powered by Patchstack's RapidMitigate technology, successfully blocked over 1.5 million exploitation attempts across more than 68,000 hosted sites. This proactive measure addresses the escalating challenge of rapid vulnerability disclosures within the WordPress ecosystem, where new flaws are often weaponized within hours of being revealed.
The integration means customers do not need to take any action; protection is applied automatically. Kinsta's existing security measures, including isolated containers, Cloudflare-powered DDoS protection, a managed edge firewall, and Bot Protection, are now augmented by this application-layer defense. This move signifies a shift in the hosting industry, positioning vulnerability mitigation as a core component of hosting services rather than an optional add-on.
Kinsta CEO Jon Penland highlighted the industry's historical reliance on site owners to manage their own security, a model that has become increasingly untenable due to the accelerated pace of vulnerability discovery and exploitation. "We identify which ones affect a customer’s site and apply protection automatically, so customers don’t have to chase them," Penland stated, emphasizing the host's commitment to simplifying security for its users.
The urgency for such solutions is underscored by recent data: 46% of WordPress vulnerabilities disclosed in 2025 lacked a vendor fix at the time of disclosure. Furthermore, the State of WordPress Security in 2026 report indicated a 42% year-over-year increase in disclosed vulnerabilities, with plugins accounting for 91% of all flaws. The median time for mass exploitation of heavily targeted plugin flaws is now just five hours, a timeline further compressed by advancements in AI-driven attack methods.
Patchstack's RapidMitigate technology operates in three stages: identification of affected sites based on Kinsta's plugin and theme inventory, mitigation through application-layer rules that block exploit traffic without altering site code, and automatic removal of these rules once the vulnerable software is updated or removed. This process is designed to be lightweight, adding no meaningful load to the server.
For agencies and site owners, this integration translates to reduced emergency response, allowing for proper testing of updates before deployment. It also mitigates risks associated with abandoned plugins or unpatched vulnerabilities, providing a crucial buffer while longer-term solutions are implemented. While software updates remain essential for addressing root causes, Kinsta's proactive protection closes the critical window between vulnerability disclosure and patch application.
This partnership between Kinsta and Patchstack aims to set a new standard for WordPress hosting security, offering a comprehensive, automated defense that shields sites from the ever-present threat of exploitation. The success of this initiative could pave the way for similar integrations across the broader hosting landscape, enhancing the security posture of the entire WordPress ecosystem.
