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 2-adımlı Doğrulama

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.

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).

Giriş Koruması

Brute force saldırıları Defender için bir maç değil. Giriş denemelerini kullanıcıların şifreleri tahmin etmeye çalışmasını durdurmak için sınırlayın. Belirli sayıda yanlış giriş denemesinden sonra IPleri kalıcı olarak engelleyin yada belirli bir süreliğine kilitleyin.

Giriş Ekranı Maskeleme

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.

404 Limitleyicisi

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.

Diğer güvenlik eklentileri yerine neden Defender’ı seçmeliyim?

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.

WordPress sitemi korurken Defender ihtiyacım olan tek güvenlik adımı mı?

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.

I have sworn by WPMUDEV plugins for a very long time, I wish you could still have a basic plugin subscription, but even the Free version of Defender provides awesomely powerful tools to help you get started. Thank WPMUDEV Y'all rock! Matthew

I have had three sites hacked - destroying years - YEARS - of work. This plug in seems to be working - at least I get notices of it blocking login attempts. It was easy for non-techie me to use - just hit activate and it's running.

Excellent plugin! Lightweight and powerful, with the ability to whitelist and blacklist.
