Learn The Ropes With These Hands-On Defender Tutorials

WordPress Security Scans

Run free malware scans that check WordPress for suspicious code and malware. The Defender scan tool compares your WordPress install with the master copy in WP directory, reports changes and lets you restore the original file with a click.

谷歌雙重驗證 (Google 2-Step Verification)

Join the millions of users that make their accounts safer with Google 2-Step Verification – along with other third-party integrations like Microsoft Authenticator and Authy. Activate two-factor authentication and protect your account with both your password and your phone.

Google reCAPTCHA Integration

Add reCAPTCHA to your login, registration, and password reset pages in a couple of steps to help protect from fraud and abuse. Select reCAPTCHA type, language, location, and style to suit.

Firewall and IP Manager

Keep your site safe with Defender’s IP manager and firewall. Manually block specific IPs, import a list of banned IPs and set automated timed and permanent lockouts. Defender makes it easy to block and unblock specific locations quickly thanks to its advanced firewall (WAF).

Login Protection

Brute force attacks are no match for Defender. Limit login attempts to stop users trying to guess passwords. Permanently ban IPs or trigger a timed lockout after a set number of failed login attempts.

Login Screen Masking

Defender makes it easy to move your login screen to a custom URL. Not only does login screen masking improve security, but it also lets you white label your login user experience and improves branding.

Force Password Reset

Password Reset enables you to force all users with selected roles to reset their password at any time. Especially helpful if you suspect a possible data breach on your site.

Security Headers

Security headers protect your site against the most likely types of attacks, such as: XSS, code injection, cross site scripting, and more. You can enable the following headers:

  • X-Frame-Options
  • X-XSS-Protection
  • X-Content-Type-Options
  • Strict Transport
  • Referrer Policy
  • Feature-Policy

404 Limiter

Defender detects when bots are being used to scan your site for vulnerabilities and shuts them down. The 404 limiter lets you stop the scan by detecting when a bot keeps visiting pages that do not exist, which can also save you from a giant strain on your site’s performance.

Notifications and Reports

Defender runs surveillance and sends notifications with information that matters.

Reduce Setup Time With Saved Configs

The configs module allows you to save your Defender configurations and reapply them to your other sites in just a few clicks. You can create and save an unlimited number of configurations.

Pwned Password Check

Protect your site against password leak attacks. Entered passwords are checked against public database breach records. If a password is identified as compromised, the user will be asked to change it.

常見問題

Why should I choose Defender over other security plugins?

Defender is built to add all the best hardening and security recommendations used by the pros without having to become a security expert. This means you get all the most effective and proven protection methods other services provide with fewer settings, on-click hardening and faster setup.

Is Defender the only step I need to take in securing my WordPress site?

Hackers and bot attacks are not the only threat to your site. No matter what security plugin or service you use, always be prepared with a secure backup stored in a safe location away from your live site. Security does not protect from hosting outages, server errors and accidentally lost or damaged data. We recommend Snapshot. Defender with scheduled managed backups is the best way to keep your site safe.

Does Defender protect against harmful bots?

Yes! Defender’s Firewall gives you robust site protection by allowing you to block bad bot IPs.

Can I use Defender with other security plugins?

You can. Just make sure not to enable the same features in the third-party plugin, that you also have enabled in Defender, as this might cause conflicts.

Is Defender compatible with WordPress Multisite?

Yes! The plugin is fully compatible with a multisite installation. It can be network enabled and managed from the network admin.

Does Defender offer spam protection?

A high percentage of Trackbacks and Pingbacks are spam. Defender allows you to easily disable both, giving you added protection.

Will my site be protected from DDoS attacks?

Yes. Defender’s IP banning, IP lockouts, and 404 detections can identify DDoS attacks and block bad IPs.

Help! I was already hacked. What should I do?

WPMU DEV’s expert support can advise you on how to clean up your site if it’s been hacked. Create a new thread in our support forum, or start a free 7 day trial of Defender Pro to get access to 24/7 live support.

I have another question, where’s the best place to get help?

Please open a new thread in Defender’s support forum. Our support team is always happy to help!

Am currently only using Defender for the anti lockout feature to prevent someone trying to guess passwords. So far so good, I guess its one of those cases where you hope not to ever need a reason for it 🙂
