Server hammered daily by brute-force attempts on /wp-login.

Brute-force on WordPress is constant background noise. Cloudflare WAF or a security plugin stops 95 percent before it reaches your server.

Try this first

  1. 1Front the site with Cloudflare (free tier is enough) and add a WAF rule: block all POST to /wp-login.php except from your office IP.
  2. 2No Cloudflare? Install Wordfence or Limit Login Attempts Reloaded. Both block IPs after X failed attempts.
  3. 3Don't rename /wp-login.php as a security move; that's security through obscurity and often breaks plugins. Throttle and monitor instead.
  4. 4Enable two-factor authentication for every admin. With 2FA, a stolen password is still useless.
  5. 5Disable XML-RPC if you don't use it. Many bots go in via system.multicall and bypass rate limits.
  6. 6Monitor login attempts weekly. A spike sometimes means a specific user is targeted; reset their password.

When to bring us in

Hit by coordinated attacks from many IPs at once (botnet)? A paid Cloudflare plan with Bot Management or a dedicated WAF (Sucuri) is sensible.
