PAUL BUNYAN
Products
Diamond Sierra makes two WordPress plugins. Paul Bunyan finds what slows your site, down to the plugin, file and line, and has been published since 1999. Diamond Sierra Site Defense scans your files every day, blocks attacks and protects your login page.
Both start free, with nothing locked or timed. When you need more, each has a Professional add-on sold here: a yearly license for 1, 10 or 50 sites, from $59 for Paul Bunyan Professional and $39 for Diamond Sierra Site Defense Pro, with refunds within 14 days.
Paul Bunyan for WordPress
Finds what slows your site, down to the plugin, file and line. Paul Bunyan records every request, PHP error, slow query and outside call, and gives you one ranked list of what to fix first, each item with its PB code. Logging tools since 1999.
Diamond Sierra Site Defense
Checks your site once a day and tells you in plain English what is wrong and how to fix it: a malware scan of your files and live homepage, a firewall, and login protection with two-factor login. Pro adds one-click cleanup, a recovery kit and an alert center for people who look after many sites.
How the editions work
Paul Bunyan and Diamond Sierra Site Defense are both free on WordPress.org. Each Professional add-on is a yearly license from this store, renews automatically, and can be refunded within 14 days. Your keys and renewals are under My Account › Licenses.
