Replit Launches Auto-Protect to Automate Security Patching for Live Applications

· Updated

Replit introduced Auto-Protect, an opt-in service for paying users that continuously monitors hosted applications for security vulnerabilities in external packages. When a critical threat is detected, the system uses an AI agent to automatically generate and test a fix, allowing developers to secure their production apps with two clicks.

Replit, an AI-powered platform for building and deploying software collaboratively with AI agents, launched Auto-Protect to provide 24/7 security monitoring for hosted applications. The system scans project dependencies for new CVEs (Common Vulnerabilities and Exposures). When a match is found, the platform's AI agent autonomously prepares and tests a remediation patch.

This update shifts AI assistance from the initial build phase into long-term maintenance. It extends the automated code auditing capabilities introduced earlier this week by providing a continuous defense layer for live apps. This follows the platform's shift toward proactive technical debt management where AI handles maintenance without constant human oversight.

You can enable Auto-Protect through account settings by selecting a minimum severity level for automated remediations. When a vulnerability is identified, you receive a direct link to the project's Security Center to review the proposed changes. Applying the patch and republishing the application takes just two clicks.

Still wondering? A few quick answers below.

Replit Auto-Protect is a security feature that provides 24/7 monitoring for applications hosted on the platform. It specifically tracks external packages and dependencies for newly disclosed vulnerabilities, known as Common Vulnerabilities and Exposures. When a critical threat is found, the system uses an AI agent to automatically prepare and test a security patch for the user to review.

Auto-Protect is currently available on an opt-in basis for paying Replit customers. While the feature is included for these subscribers, it is disabled by default at launch. Users must manually enable the service through their account settings to begin receiving automated security remediations and email notifications for their hosted projects and workspaces.

To enable the feature, an account admin must navigate to the Advanced section under Account settings. From there, you can select the minimum severity level, ranging from low to critical, for automatic patch preparation. You should also visit the Email Notifications settings to choose which severity levels should trigger a direct alert when a new issue is found.

When a vulnerability matches your project dependencies, the Replit Agent creates a patch and tests it. You receive an email with a link to the Security Center, where you can inspect the changes. After selecting the option to apply the patch, the fix is merged into your environment, requiring you to republish the app to secure the production version.

The Replit Security Agent is a tool used to perform deep, comprehensive security reviews and threat modeling of an entire codebase before an application is published. In contrast, Auto-Protect is a continuous, 24/7 monitoring service that specifically guards live, already-deployed applications against newly discovered vulnerabilities in third-party packages and dependencies after the initial launch.
