Web security tools

Tools for people who run a website: WordPress security plugins, backups, and firewalls, with WordPress.org figures and CVE entries since 2021.

For people who run a website. Many flaws on the timeline, PHP2Shell among them, hit servers and websites. The tools below protect WordPress, keep backups, or filter attacks before they reach the server. Features are as the makers state them. This archive adds each plugin's figures from WordPress.org and its own CVE entries. More entries do not simply mean less safety, since popular plugins are examined more often. What counts is fast fixes and installed updates.
