What it does
Anyone managing several WordPress sites knows how hard it is to keep track of which plugins, themes or core versions have known security problems. Checking each site by hand takes time, and something always slips through. This extension runs inside your existing MainWP Dashboard and compares your connected sites against the WPScan database of known WordPress vulnerabilities, giving you a single view of the issues across your network.
Scans can run automatically each day, and when a vulnerability turns up you get an alert by email or inside the dashboard. Each finding comes with details on the type of vulnerability, its severity and the recommended action, which helps you decide what to fix first. It suits agencies, developers and businesses that already use MainWP to look after many WordPress installations and want security checks handled from the same place.
Best for
- Agencies maintaining many client WordPress sites
- Freelancers already using the MainWP Dashboard
- Businesses running several WordPress installations
