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.

Google επαλήθευση σε 2 βήματα – 2FA

Now you can easily join the millions of users that make their accounts safer with Google 2-Step Verification. Activate two-factor authentication and protect your account with both your password and your phone.

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).

Προστασία σύνδεσης

Οι βίαιες επιθέσεις δεν συγκρίνονται με το Defender. Περιορίστε τις προσπάθειες σύνδεσης για να σταματήσετε τους χρήστες να προσπαθούν να μαντέψουν τους κωδικούς πρόσβασης. Απαγορεύστε οριστικά τις IP ή να ενεργοποιείστε ένα χρονικό κλείδωμα μετά από έναν καθορισμένο αριθμό αποτυχημένων προσπαθειών σύνδεσης.

Απόκρυψη σελίδας σύνδεσης

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.

Περιορισμός 404

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.

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.

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

WPMU DEV’s expert support will restore and clean up your site after it’s been hacked for free with a 30 day trial of Defender Pro. If you have a backup, we’ll minimize your downtime by activating the most recent clean version of your site. Our experts will then scan your site with Defender to find and fix known vulnerabilities, permanently remove the malicious code and set up his firewall of cyber muscle.

Since I used the plugin, my websites are much more secure; I used all the suggested tweaks and can see how many attacks are being blocked. Great job.

It does exactly what it claims to do and offers a surprising number of free options to pair with paid options that extend its utility but aren't necessary.
