Overview
Keeping track of security issues gets harder with every site you manage. Checking each installation by hand takes time, and a known weakness in a plugin or theme is easy to miss. This extension works inside your MainWP Dashboard and scans your connected WordPress sites for known vulnerabilities, using data from the WPScan vulnerability database.
Scans can run on a daily schedule, so checks happen without manual effort. When something turns up, you get an alert by email or in the dashboard, along with a report that describes the type and severity of the issue and the recommended action. All results sit in one MainWP dashboard, which suits agencies, developers and businesses that look after many WordPress installations.
Features
- Automated daily scans: Schedule regular vulnerability checks across all connected WordPress sites, so monitoring continues without anyone having to start each scan by hand.
- WPScan vulnerability data: Scans compare your sites against the WPScan database of known WordPress vulnerabilities, so reported issues are based on documented weaknesses.
- Centralized results: View scan results and vulnerability alerts from multiple websites in a single MainWP dashboard instead of checking each site separately.
- Alerts by email or dashboard: Get notified when a vulnerability is detected, either by email or inside the dashboard, so you can respond to the issue promptly.
- Detailed vulnerability reports: Each finding comes with the type of vulnerability, its severity and a recommended action, which helps you decide what to fix first.
- Light on site performance: Scans are designed to run without interrupting the experience of visitors on the sites being checked.
- Works within MainWP: The extension is managed from your existing MainWP Dashboard, so security checks sit alongside the rest of your site management.
- Built for multiple sites: Coverage extends across numerous WordPress installations, which fits agencies and developers who manage a whole network of client sites.
Best for
- Agencies managing many client WordPress sites
- Developers who already use the MainWP Dashboard
- Businesses running a network of WordPress installations
