Atlant

<p><strong>Atlant Security</strong> is a comprehensive WordPress security plugin that provides enterprise-grade protection through 17 integrated security modules organized in a 5-layer defense architecture.</p>
<h4>5-Layer Defense Architecture</h4>
<ol>
<li><strong>Pre-WordPress WAF</strong> — Firewall, rate limiter, and IP blocking run before WordPress processes the request.</li>
<li><strong>Application-Aware</strong> — Login security, custom login URL, two-factor authentication, session hardening, cron monitoring, and REST API policies.</li>
<li><strong>Content & Config</strong> — WordPress hardening, security headers, AI crawler management, and honeypot traps.</li>
<li><strong>Outbound & Data</strong> — SSRF prevention, malware scanning (files and database).</li>
<li><strong>Response & Recovery</strong> — Post-breach recovery, notifications, visitor log, and audit log.</li>
</ol>
<h4>Key Features</h4>
<p><strong>Web Application Firewall (WAF)</strong><br />
Inspects every request against 28+ attack pattern families including SQL injection, XSS, remote code execution, path traversal, PHP object injection, and WordPress-specific attacks. Block or log-only mode. Triple URL decoding prevents evasion.</p>
<p><strong>Brute Force Protection</strong><br />
Progressive lockout system (5 min > 30 min > 24 hours) with configurable thresholds. Generic login error messages prevent username enumeration. Author enumeration blocking.</p>
<p><strong>Malware Scanner</strong><br />
Local file and database scanner with 38 malware signatures. Detects backdoors, webshells (WSO, c99, r57), crypto miners, credit card skimmers, and obfuscated code. Quarantine system with web access blocking.</p>
<p><strong>Two-Factor Authentication (2FA)</strong><br />
TOTP (Google Authenticator, Authy) and email OTP. Per-role enforcement, 10 recovery codes, 5-minute challenge timeout, replay attack prevention.</p>
<p><strong>Honeypot Traps</strong><br />
Zero-false-positive bot detection: hidden link traps, fake login pages, comment honeypots, and Contact Form 7 integration. 3-layer safe bot protection ensures Googlebot, Bingbot, and allowed AI crawlers are never blocked.</p>
<p><strong>AI Crawler Management</strong><br />
Control 20+ known AI/LLM training crawlers (GPTBot, ClaudeBot, Google-Extended, Bytespider, and more). Per-crawler toggles, robots.txt integration, and 403 enforcement. Block training crawlers while allowing browsing bots.</p>
<p><strong>Security Headers</strong><br />
Manage HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, CSP, CORP, and COOP. Letter-grade scoring system. Remove X-Powered-By and Server headers.</p>
<p><strong>Session Security</strong><br />
Cookie hardening (HttpOnly, Secure, SameSite). Session binding via IP + User-Agent fingerprint detects hijacking. Concurrent session limits. Idle timeout. Optional admin bypass for all session restrictions.</p>
<p><strong>Rate Limiter</strong><br />
Sliding-window rate limiting across 11 endpoint categories: frontend, login, search, feed, REST API, WooCommerce checkout, XML-RPC, and cron.</p>
<p><strong>REST API Policies</strong><br />
Per-route access control with authentication requirements, HTTP method restrictions, rate limits, and IP whitelists. 5 built-in policies protect user enumeration, search, and write endpoints.</p>
<p><strong>Cron Guard</strong><br />
Monitors wp-cron.php for flood attacks. Detects suspicious scheduled tasks via baseline comparison. System cron migration helper.</p>
<p><strong>Outbound Monitor (SSRF Prevention)</strong><br />
Monitors all outgoing HTTP requests. Blocks requests to private/internal IP ranges including cloud metadata endpoints. Domain allowlist with wildcard support. Caller detection traces requests to specific plugins.</p>
<p><strong>Post-Breach Recovery</strong><br />
12 emergency actions: terminate sessions, force password reset, rotate secret keys, emergency lockdown, reinstall core, reinstall plugins, audit admin accounts, clear caches, malware scan, disable plugins, and downloadable incident report.</p>
<p><strong>Real-Time Dashboard</strong><br />
Live visitor monitoring with 15-second auto-refresh. Stat cards, traffic charts, top IPs with VirusTotal integration, browser distribution, and IP detail modals.</p>
<p><strong>Visitor Log & Audit Log</strong><br />
Complete request history with filters (IP, URL, bots, blocked, time range). Tamper-resistant admin action audit trail.</p>
<p><strong>Notifications</strong><br />
Email alerts (HTML formatted, color-coded severity), Slack webhooks, custom JSON webhooks, and daily digest. Configurable severity threshold with 5-minute deduplication.</p>
<p><strong>WordPress Hardening</strong><br />
One-click toggles: disable XML-RPC, hide WordPress version, block REST API user enumeration, block author enumeration, disable file editor, block PHP execution in uploads.</p>
<h4>What Makes Atlant Security Different</h4>
<ul>
<li><strong>Pre-WordPress WAF</strong> — Blocks attacks via auto_prepend_file before WordPress even loads</li>
<li><strong>Outbound HTTP Monitor</strong> — Detects SSRF attacks and unauthorized outbound connections</li>
<li><strong>Database Backdoor Scanner</strong> — Scans wp_options and wp_posts for eval(), base64, and hidden backdoors</li>
<li><strong>Client-Side Bot Detection</strong> — JavaScript challenges and browser fingerprinting catch sophisticated bots</li>
<li><strong>AI/LLM Crawler Blocking</strong> — Identify and block AI training crawlers scraping your content</li>
<li><strong>Honeypot Traps</strong> — Hidden links, fake login pages, invisible form fields that only bots trigger</li>
<li><strong>Cron Guard</strong> — Monitors wp-cron for unauthorized scheduled tasks planted by malware</li>
<li><strong>Post-Breach Recovery</strong> — Guided recovery toolkit with 12 emergency actions in one place</li>
<li><strong>Session Fingerprint Binding</strong> — Binds sessions to IP + User-Agent so stolen cookies are useless</li>

<h4>Plugin Tutorial</h4>
<p>Unveil the vast array of features and unleash the full potential of our security plugin in our <a href="https://www.siteground.com/tutorials/wordpress/sg-security/" rel="nofollow ugc">Security Optimizer Tutorial</a>.</p>
<h3>SITE PROTECTION FEATURES</h3>
<p>Safeguard your WordPress application using our powerful site security toolset. Our comprehensive features are specifically designed to strengthen your website’s defenses against malware, exploits, and various malicious activities. With these tools at your disposal, you can ensure the utmost bot, malware and brute force protection for your website:</p>
<h4>Lock and Protect System Folders</h4>
<p>Ensure the maximum security for your application’s system folders by preventing the execution of any unauthorized or malicious scripts. The Lock and Protect System Folders feature acts as a powerful shield against potential threats.</p>
<h4>Hide WordPress Version</h4>
<p>Protect your website from mass attacks by hiding the WordPress version, which helps to mitigate version-specific vulnerabilities.</p>
<h4>Disable Themes & Plugins Editor</h4>
<p>Enhance the security of your WordPress admin area by disabling the Themes & Plugins Editor, preventing potential coding errors and unauthorized access through the editor.</p>
<h4>Disable XML-RPC</h4>
<p>Mitigate potential security risks by disabling the XML-RPC protocol, which has been exploited in various attacks. Please note that disabling XML-RPC will restrict WordPress from communicating with third-party systems. We recommend enabling this feature unless you have a specific need for it.</p>
<h4>Disable RSS and ATOM Feeds</h4>
<p>Prevent content scraping and specific attacks on your site by disabling RSS and ATOM feeds. Unless you have readers accessing your site via RSS readers, it is recommended to keep this feature enabled.</p>
<h4>Advanced XSS Protection</h4>
<p>Add an extra layer of website security against cross-site scripting (XSS) attacks by enabling Advanced XSS Protection, bolstering the overall security of your website.</p>
<h4>Delete Default Readme.html</h4>
<p>Eliminate potential vulnerabilities by deleting the default readme.txt file, which contains information about your website. By removing this file, you reduce the risk of your site being listed in vulnerable sites targeted by hackers.</p>
<h3>Login Security</h3>
<h4>Custom Login Url</h4>
<p>Personalize your login URL to thwart potential attacks and create a strong entry point. Bid farewell to the default login URL and embrace a bespoke path of your choosing. Additionally, you have the freedom to modify the default sign-up URL as well.</p>
<h4>Login Access</h4>
<p>Restrict login page access to specific IP addresses or IP ranges, effectively thwarting malicious login attempts and deterring brute force attacks.</p>
<h4>2FA (Two-Factor Authentication)</h4>
<p>Immerse your website in an impenetrable shield of security with 2FA. This formidable feature demands that all admin users furnish a unique token, generated exclusively through the Google Authentication application, during the login process.</p>
<h4>Disable Common Usernames</h4>
<p>Don’t fall victim to predictable security breaches! The use of common usernames, such as ‘admin,’ poses a significant threat to the integrity of your website. Activate this option to disable the creation of common usernames. If any weak usernames already exist, we’ll prompt you to provide new, stronger alternatives.</p>
<h4>Limit Login Attempts</h4>
<p>Maintain control over unauthorized access attempts with Limit Login Attempts. Set a specific threshold for the number of login failures users can endure before consequences arise. After reaching the limit, the IP address associated with the unsuccessful login attempts will be blocked for one hour. Persistent failures will result in longer restrictions, starting with 24 hours and escalating to a week.</p>
<h3>ACTIVITY MONITORING</h3>
<p>Monitor your website and login page for unauthorized visitors and brute force attempts to prevent malicious actions</p>
<h4>Activity Log</h4>
<p>The Activity Log page provides you with a comprehensive view of the activities performed by registered, unknown, and blocked visitors. It allows you to closely monitor any suspicious behavior and take appropriate actions in case of a compromised user, plugin, or hacking attempt. You can leverage the quick tools available to swiftly block future attempts.</p>
<h4>Weekly Security Reports</h4>
<p>Receive a weekly traffic summary for your website directly to your inbox. This <strong>Weekly Security Report</strong> compiles data on both bot and human traffic, along with details about blocked login and visit attempts to proactively monitor traffic and promptly identify suspicious activity.</p>
<h3>POST-HACK ACTIONS</h3>
<p>Take immediate measures to protect your website if you suspect a compromise and prevent further damage. Here, you’ll find convenient solutions to address the situation effectively:</p>
<h4>Reinstall All Free Plugins</h4>
<p>In the event of a hack, utilizing the Reinstall All Free Plugins feature can help mitigate potential harm. This action reinstalls all of your free plugins, reducing the likelihood of additional exploits or the reuse of malicious code.</p>
<h4>Log Out All Users</h4>
<p>To prevent any further unauthorized activities by users or attackers, you can choose to log out all users instantly using the Log Out All Users feature.</p>
<h4>Force Password Reset</h4>
<p>By enforcing a password reset, you can ensure that all users are prompted to change their passwords during their next login. This not only strengthens the security of their accounts but also immediately logs out all currently logged-in users.</p>
<h3>Requirements</h3>
<ul>
<li>WordPress 4.7</li>
<li>PHP 7.0</li>
<li>Working .htaccess file</li>
</ul>
<h3>Data Collection</h3>
<p>Collection of technical data is optional and is <a href="https://www.siteground.com/kb/what-information-wp-plugins-collect" rel="nofollow ugc">listed here</a>. This data is collected only for technical analysis, improvements and the possibility to contact the plugin user in case urgent issues need to be fixed (for example a critical security release that needs to be communicated to site owners). The plugin user can manage their preferences within the WP admin to control the collection of technical data. We advise opting in for this data collection, as it can enhance the plugin’s performance. You may find more information on data collection in our <a href="https://www.siteground.com/viewtos/siteground_plugins_privacy_notice" rel="nofollow ugc">Plugins Privacy Notice</a>.</p>


Security Optimizer – The All-In-One Protection Plugin

Yesterday I started researching a new security plugin that I could switch to for all my WordPress sites (about 50). Skimming the plugin directory I found SiteGround Security and I must say this is the most promising looking plugin I have ever encountered!

The biggest PRO for me: SiteGround is a professional hosting service and they are using this plugin on all WordPress sites they host, so they will have a strong motivation to keep sg-security as high-quality as possible, without the need to upsell it like so many other plugins are doing it.

I have two questions: 

1. Is there a place where you host the plugin's source publicly, like for example on GitHub? I couldn't find anything except a security warning about 2FA in an earlier version (1.2.5, can't post link here due to WP guidelines).

2. What was your reasoning behind not making the limit_login_attempts periods (1 hour, 1 day, 1 week) un-filterable? I wanted to immediately reduce the first period to something like 20 minutes, but those periods are hard-coded right now inside SG_Security\Login_Service\Login_Service->log_login_attempt( $error ) (Version 1.3.7).

Thanks again.

Wow!


Llevo decenas de webs de clientes y he encontrado muchas webs infectadas con plugins de seguridad premium. 



Tras instalar el plugin de seguridad de SiteGround y un buen cortafuegos nunca más he tenido problemas en ninguna web.


Sencillo y efectivo, mejor que el resto


Cannot unsubscribe from the emails without admin access. In my experience, this makes the plugin extremely annoying. They do not plan to fix this.
