Ultimate Security – Vulnerability Scanner, 2FA, and Login Protection

Description

Ultimate Security handles the traffic that actually reaches a WordPress site: automated login attempts, brute-force runs, comment and form spam, and probes at well-known paths. It covers two-factor authentication, login lockouts, CAPTCHA, a movable login URL, session controls, vulnerability scanning, and Cloudflare edge rules — set up from one admin screen, without editing files or writing firewall rules by hand.

There is no usage tracking and nothing phones home. The plugin contacts an outside service only when you switch on a feature that needs one, and each is listed under External Services below. Features that belong to the Pro add-on are labelled as such.

Setup wizard

The first run is a five-step wizard. You answer a few questions about the site, it runs a quick scan, and you pick one of seven starting templates: basic, moderate, strict, agency, blog, membership, or WooCommerce. Before it changes anything it shows you a full diff, and you can undo everything it did later without losing edits you made yourself. It also gives you an emergency access link — keep it somewhere safe, and you can switch the plugin off from a browser if you ever lock yourself out.

Two-factor authentication

• Email one-time codes, no app required, for any user.
• Authenticator apps (TOTP and HOTP) with QR enrolment — Google Authenticator, Authy, Microsoft Authenticator and similar.
• Per-role configuration: pick which roles use email codes and which use an app.
• Rate limiting on code entry, with a configurable attempt limit and lockout.
• Optional 2FA event logging.
• Covers the WordPress, WooCommerce and Ultimate Member login forms, with a separate setting for XML-RPC.

Login access control

• Move wp-login.php to a secret URL so bots can’t find it, with a configurable post-login redirect.
• HTTP Basic Authentication in front of wp-login.php and wp-admin, no .htaccess editing. The password is stored hashed, repeated failures trigger a lockout, and you can let trusted IPs through.
• Show your own consent or policy text on the login form.

Password policies

• Require a minimum length, mixed case, numbers and special characters, or start from a preset.
• Expiry with advance warning, a grace period, and email notification.
• Password history, so old passwords can’t be reused.
• Force a password change on first login.
• Reject compromised passwords, checked against the Have I Been Pwned range API by k-anonymity — the password itself never leaves the site.
• Optionally turn off self-service password reset and point people at your own process instead.

Brute-force protection

• Limit failed logins and lock offenders out automatically.
• Progressive lockouts, so repeat offenders wait longer each time.
• Configurable retry-reset window, plus a permanent block list.
• A one-time recovery link, so a lockout doesn’t strand you.

Session management

• Limit concurrent logins per user; block the new login or end the oldest session.
• Idle timeout for inactive sessions.
• HttpOnly, Secure and SameSite flags on auth cookies.
• Optionally bind a session to its IP and/or browser to catch hijacking.

CAPTCHA and spam

• Google reCAPTCHA v2 and v3, with a v3 score threshold, IP and user-agent allowlists, a bypass for logged-in users, and a verification log.
• Cloudflare Turnstile, with theme, size, language and appearance options, deferred loading, custom failure messages, and its own log.
• Both cover the WordPress login, registration, lost-password and comment forms, and the WooCommerce login, registration, lost-password and checkout forms.
• No-conflict mode and provider priority keep two CAPTCHAs off the same form.
• Validate your site and secret keys from the settings page before going live.
• If the provider is unreachable, forms keep working.

Vulnerability scanning

• Scans WordPress core, plugins and themes for known vulnerabilities.
• No API key needed — it uses the keyless WPVulnerability database by default.
• Add a WPScan or Patchstack key for more coverage, with automatic failover between providers.
• Scheduled scans and email alerts, filtered by severity.
• Flags plugins that haven’t been updated in a long time.
• Scan history, run-to-run comparison, and an ignore list for findings you’ve accepted.
• Results show up in Site Health, the dashboard widget, the plugins list, and menu counters.

Cloudflare WAF rules

Connect your own Cloudflare account and manage edge rules from wp-admin.

• Let verified search, monitoring, backup, SEO and social crawlers through.
• Block aggressive crawlers and sensitive WordPress paths.
• Block data-center hosts and TOR exit nodes.
• Challenge large cloud providers and specific countries.
• Challenge VPN traffic and requests to wp-login.php.
• Virtual patches that block requests exploiting known core CVEs at the edge until you can update.
• Preview the generated expressions before deploying, review the live rules on your zone, and read request, threat and bandwidth analytics.

Security keys (salts)

• Rotate the keys and salts in wp-config.php on demand or on a schedule — daily, weekly, monthly, quarterly, or twice a year.
• Advance notice before a scheduled rotation, so the forced re-login isn’t a surprise.
• Quiet hours, plus pause and skip-next controls.
• Rotation history, with the option to restore a previous set.

Update manager

• Set auto-update policy for core, plugins and themes, with per-plugin and per-theme overrides.
• Update windows, allowed days, and freeze periods for when you don’t want changes.
• Delay updates by a set number of days to let others hit the bugs first.
• Optional maintenance mode during updates, and detection of version-controlled installs.
• Email notifications and a daily digest.

Monitoring, security score and logs

• A security score with a per-check breakdown of what’s pulling it down.
• Activity log for logins, logouts, lockouts, and 2FA and password events, with a retention period you set.
• Session log for session events and anomalies.
• A “who’s online” view of currently active users.
• Core file-integrity check against the official WordPress.org checksums.
• Site Health entries covering plugin, server, database, filesystem, theme and WordPress diagnostics.
• A dashboard widget summarising failed logins, issues found, outdated plugins and the current score.

Test mode

Run your rules without blocking anyone and review a log of what would have been blocked before you enforce it. Choose which roles it applies to, keep admins excluded, and an admin-bar marker plus a dashboard notice remind you it’s on.

Tools, migration and backup

• Import from Wordfence Login Security — preview what comes across, run it, and roll it back if you change your mind.
• Export and import settings as JSON for staging-to-production moves or recovery.
• Reset all settings to defaults, and clear the plugin cache.
• Diagnostics for REST API, cron (with a manual run trigger), and server status.
• An emergency deactivation URL that switches the plugin off if you’re locked out.

Works with what you already run

Ultimate Security detects and adapts to WooCommerce, Ultimate Member, common page builders, form plugins, caching plugins and SEO plugins, and warns you when another security plugin is already doing the same job.
