SiteGround Security


With the carefully selected and easy to configure functions the SiteGround Security plugin provides everything you need to secure your website and prevent a number of threats such as brute-force attacks, compromised login, data leaks, and more.

Login Settings

Here you can use the tools we’ve developed to protect your login page from unauthorized visitors, bots, and other malicious behavior.

Custom Login URL

Change the default login url to prevent attacks and have an easily memorisable login URL. You can also change the default sign-up url if you have that option enabled for your website.

You can revert to the default login type by using the following snippet.

add_action( 'init', 'remove_custom_login_url' );
function remove_custom_login_url() {
    update_option( 'sg_security_login_type', 'default' );

Login Access

Login Access allows you to limit the access of the login page to a specific IP’s or a range of IP’s to prevent malicious login attempts or brute-force attacks.

If you lock yourself out of your admin panel, you can add the following option to your theme’s function.php, reload the site and then remove it once you have gained access. Keep in mind that this will also remove all IP’s that are allowed to access the login page and a re-configuration will be needed:

add_action( 'init', 'remove_login_access_data' );
function remove_login_access_data() {
    update_option( 'sg_login_access', array() );

Two-factor Authentication

Two-factor Authentication for Admin User will force all admins to provide a token, generated from the Google Authentication application when logging in.

You can force other roles to use the Two-Factor authentication as well. Once enabled, you can add your filter as the following.

add_filter( 'sg_security_2fa_roles', 'add_user_roles_to_2fa' );
function add_user_roles_to_2fa( $roles ) {
    $roles[] = 'your_role';
    return $roles;

Disable Common Usernames

Using common usernames like 'admin' is a security threat that often results in unauthorised access. By enabling this option we will disable the creation of common usernames and if you already have one ore more users with a weak username, we’ll ask you to provide new one(s).

Limit Login Attempts

With Limit Login Attempts you can specify the number of times users can try to log in with incorrect credentials. If they reach a specific limit, the IP they are attempting to log from will be blocked for an hour. If they continue with unsuccessful attempts, they will be restricted for 24 hours and 7 days after that.

If you lock yourself out of your admin panel, you can add the following option to your theme’s function.php, reload the site and then remove it once you have gained access. Keep in mind that this will also remove the unsuccessful attempts block for all IP’s:

add_action( 'init', 'remove_unsuccessfull_attempts_block' );
function remove_unsuccessfull_attempts_block() {
    update_option( 'sg_security_unsuccessful_login', array() );

Site Security

With this toolset you can harden your WordPress аpplication and keep it safe from malware, exploits and other malicious actions.

Lock and Protect System Folders

Lock and Protect System Folders allows you to block any malicious or unauthorized scripts to be executed in your applications system folders.
If the Lock and Protect System Folders option blocks a specific script used by another plugin on the website, you can easily whitelist the specific script by using the snippets provided below.

Use this one to whitelist a file in the wp_includes folder:

add_filter( 'sgs_whitelist_wp_includes' , 'whitelist_file_in_wp_includes' );
function whitelist_file_in_wp_includes( $whitelist ) {

    $whitelist[] = 'file_name.php';
    $whitelist[] = 'another_file_name.php';

    return $whitelist;

Use this one to whitelist a file in the wp_uploads folder:

add_filter( 'sgs_whitelist_wp_uploads' , 'whitelist_file_in_wp_uploads' );
function whitelist_file_in_wp_uploads( $whitelist ) {
    $whitelist[] = 'file_name.php';
    $whitelist[] = 'another_file_name.php';

    return $whitelist;

Use this one the whitelist a file in the wp_content folder:

add_filter( 'sgs_whitelist_wp_content' , 'whitelist_file_in_wp_content' );
function whitelist_file_in_wp_content( $whitelist ) {
    $whitelist[] = 'file_name.php';
    $whitelist[] = 'another_file_name.php';

    return $whitelist;

Hide WordPress Version

When using Hide WordPress Version you can avoid being marked for mass attacks due to version specific vulnerabilities.

Disable Themes & Plugins Editor

Disable Themes & Plugins Editor in the WordPress admin to prevent potential coding errors or unauthorized access through the WordPress editor.

Disable XML-RPC

You can Disable XML-RPC protocol which was recently used in a number of exploits. Keep in mind that when disabled, it will prevent WordPress from communicating with third-party systems. We recommend using this, unless you specifically need it.

Force HTTP Strict-Transport-Security (HSTS)

HSTS (HTTP Strict-Transport-Security) is a response header. It allows the website to tell browsers that it should only be accessed using HTTPS, instead of using HTTP. Тhis prevents "man-in-the-middle" attacks and ensures that regular visitors will redirected to the secure version of the website.

Disable RSS and ATOM Feeds

Disable RSS and ATOM Feeds to prevent content scraping and specific attacks against your site. It’s recommended to use this at all times, unless you have readers using your site via RSS readers.

Advanced XSS Protection

By enabling Advanced XSS Protection you can add an additional layer of protection against XSS attacks.

Delete the Default Readme.txt

When you Delete the Default Readme.txt which contains information about your website, you reduce the chances of it ending in a potentially vulnerable sites list, used by hackers.

Activity Log

Here you can monitor in detail the activity of registered, unknown and blocked visitors. If your site is being hacked, a user or a plugin was compromised, you can always use the quick tools to block their future actions.

You can set a custom log lifetime ( in days ), using the following filter we have provided for that purpose.

add_filter( 'sgs_set_activity_log_lifetime', 'set_custom_log_lifetime' );
function set_custom_log_lifetime() {
    return 'your-custom-log-lifetime-in-days';

Post-Hack Actions

Reinstall All Free Plugins

If your website was hacked, you can always try to reduce the harm by using Reinstall All Free Plugins. This will reinstall all of your free plugins, reducing the chance of another exploit or the re-use of malicious code.

Log Out All Users

You can Log Out All Users to prevent any further actions done by them or use.

Force Password Reset

Force Password Reset to force all users to change their password upon their next login. This will also log-out all current users instantly.

WP-CLI Support

Just like all Siteground products, this plugin is great! Love the logging function. Kudos SG team! Only 1 suggestion, the timestamp is not local, so please help to fix :).

En general va muy bien exceptuando algunos pequeños detalles. En lo que lo "pulen" o "mejoran" le daré (por ahora) 4 estrellas. Pero eso sí: Es muy recomendable!

If you have low traffic website and are looking to make your admin area more secure, this is the best plugin for you. It helps to easily overcome some of the common vulnerabilities in WordPress, like XML-RPC. The best feature so far in the plugin is a simple and light 2FA authentication, unlike other such plugins it does not have any effect on the performance of the site.

I was about to drop 200 dollars for iThemes Security Pro, but I realized that SiteGround already has a security plugin installed on my website. I found it to be very easy to use, and has the exact features I was looking for without having to pay the extra money. Very well done, and the developers seem to be quite active with rolling out new features.

Un plugin sencillo de configurar, con las opciones precisas, casi 'minimal style & functional'. No te complica la vida en absoluto, está todo muy bien explicado así que ayudará a todos. Después de haber utilizado durante mucho tiempo otros conocidos plugins muy enrevesados y con miríadas de opciones (el 80% para versión premium), encontrar SiteGround Security ha sido todo un descubrimiento y un alivio. Recomendabilísimo 100%. * * * * * 😉 Thumbs up!
