Description

SiteGuard WP Plugin helps protect WordPress sites by strengthening login and admin-area security. It helps reduce brute-force login attacks, password list attacks, comment spam, and unauthorized access to /wp-admin/.

Main Features

  • Admin Page IP Filter: Restricts wp-admin access to IP addresses that have successfully logged in.
  • Rename Login: Changes the URL of the login page from wp-login.php to a custom path.
  • CAPTCHA: Adds CAPTCHA to login, comment, password reset, and user registration forms.
  • Login Lock: Temporarily locks out IP addresses after repeated failed login attempts.
  • Login Alert: Sends email notifications when users log in.
  • Fail Once: Intentionally rejects the first valid login attempt and requires the user to try again shortly after.
  • Protect XML-RPC: Disables pingbacks or all XML-RPC access to help prevent abuse.
  • Block Author Query: Helps prevent username leakage through /?author=<number> requests.
  • Update Notifications: Sends email notifications when updates are available for WordPress core, plugins, or themes.
  • WAF Tuning Support: Creates exclusion rules to help prevent false positives when SiteGuard Server Edition WAF is installed.

Requirements and Compatibility

  • WordPress multisite is not supported.
  • Apache 1.3, Apache 2.x, and Nginx are supported.
  • Rename Login cannot be combined with a login page URL change feature in another plugin. Enable it in only one plugin; using both can leave two login URLs available, or stop the login page from loading.
  • CAPTCHA requires the PHP extensions mbstring and gd.
  • WAF Tuning Support requires SiteGuard Server Edition on Apache.

Unsafe

By alexbrowp on November 27, 2024

When you log out, the session is not closed and you can still go to wp-admin. Also, redirecting wp-admin to the custom login page doesn't help with security

誰でもユーザーを登録できるサイトを作っているのですが、ログイン保護機能を利用しています。スパムアカウントが減りました。

解決済/ループバックリクエストでの問題(サイトヘルス)

By tsutlnps149 on February 6, 2021

管理ページアクセス制限を有効にすると、サイトヘルスで「サイトでループバックリクエストが完了できませんでした」という文字が出るが、この問題、site-health.phpを除外設定にしてもなお出続ける。 制限をOFFにすると、出なくなる。 バージョン「1.5.1」でのアップデートで、この問題は解決したようです。ありがとうございました。

ログインしていない状態で/wp-admin/にアクセスするとurl変更したログイン画面にリダイレクトされてしまう

By Anonymous User 16694661 (anonymized_16694661) on December 12, 2018

ワードプレスのデフォルトの仕様だと思いますが、/wp-admin/にアクセスするとプラグインで変更したログイン画面のurlヘリダイレクトされてしまいますのでこちらの改善もお願いいたします。 例) example.co.jp/wp-admin ↓ リダイレクト example.co.jp/プラグインで設定したログイン画面のURL文字列 個人的には下記のコードで対処しています。

add_action('init', 'remove_default_redirect');
add_filter('auth_redirect_scheme', 'stop_redirect', 9999);

function stop_redirect($scheme)
{
    if ( $user_id = wp_validate_auth_cookie( '',  $scheme) ) {
        return $scheme;
    }

    global $wp_query;
    $wp_query->set_404();
    get_template_part( 404 );
    exit();
}
よろしくお願いいたします。

Great tool, simple yet powerful.

By unostar on October 29, 2017

Like the simplicity and efficiency of the plugin. One thing I would really like to change is CAPTCHA. C'mon guys, haven't you seen Google's reCAPTCHA? It's way much better, imo.

大変良いプラグインです

By Tomo (tomoygt6) on September 29, 2017

ログインページの変更するなどの機能の他、不正にログインしようとしてきた履歴を見れるなど、一通りのセキュリティを提供してくれる良いプラグインです。

1.8.9

  • Update Notifications: fixed notification emails still being sent while the feature was set to OFF.
  • CAPTCHA: fixed a fatal error on the login page on servers that cannot render the CAPTCHA image. CAPTCHA is now skipped so that login remains available, and the reason is shown on the settings screen.
  • CAPTCHA: fixed login becoming impossible when the CAPTCHA working directory could not be written to by the web server. This is now detected and reported instead of failing silently.
  • Confirmed compatibility with WordPress 7.1.

Special thanks to miruko for the update notification report.

1.8.8

  • Rename Login: shows a warning when another active plugin is also changing the login page URL.
  • Rename Login: fixed an issue where a fresh install could leave the login page inaccessible (the login URL returned 404).

Special thanks to niflex for the plugin conflict report, and to kitadahi for the login URL report.

1.8.7

  • Fixed a cross-site scripting (XSS) vulnerability in the logout URL that could occur when the login page URL is changed.

Special thanks to daroo (Patchstack) for the report.

1.8.6

  • Rename Login: when the login URL falls back to the .php (stub) form, the settings screen now explains why .htaccess could not be used.
  • Rename Login: fixed the .htaccess self-test so it works when WordPress has been given its own directory (the WordPress Address differs from the Site Address).
  • Block Author Query: the “Disable REST API” exclusion list now uses REST API namespaces instead of plugin names.

Special thanks to abcdrew and miwarock777 for their contributions to this release.

1.8.5

  • Fixed a security issue affecting the login URL protection on some server configurations.

  • Fixed an issue where upgrading from 1.7.x to 1.8.x could leave legacy .htaccess rules in place, locking administrators out of /wp-admin/.
