The dashboard gives you an overview of your site's security including notifications, attack statistics and Wordfence feature status.
The Web Application Firewall protects your site from common types of attacks and known security vulnerabilities.
The Wordfence Malware Scanner lets you know if your site has been compromised and alerts you to other security issues that need to be addressed.
The Wordfence Security Live Traffic view shows you real-time activity on your site including bot traffic and exploit attempts.
Block IPs that are known to be malicious, manage IPs that have been locked out and see recently throttled IPs that violated security rules.

The Advanced Options page allows technically-minded users fine-tune their security settings.
Secure your website with Wordfence.
Secure your website using the following steps to install Wordfence:
- Install Wordfence Security automatically or by uploading the ZIP file.
- Activate the security plugin through the ‘Plugins’ menu in WordPress.
- Wordfence WordPress Security is now activated. Go to the scan menu and start your first security scan. Scheduled security scanning will also be enabled.
- Once your first scan has completed a list of security threats will appear. Go through them one by one to secure your site.
- Visit the Wordfence Security options page to enter your email address so that you can receive email security alerts.
- Optionally change your security level or adjust the advanced options to set individual security scanning and protection options for your site.
- Click the “Live Traffic” menu option to watch your site activity in real-time. Situational awareness is an important part of website security.
To install the Wordfence WordPress security plugin on WordPress Multi-Site installations:
- Install Wordfence Security via the plugin directory or by uploading the ZIP file.
- Network Activate Wordfence Security. This step is important because until you network activate it, your sites will see the plugin option on their plugins menu. Once activated that option dissapears.
- Now that Wordfence is network activated it will appear on your Network Admin menu. Wordfence Security will not appear on any individual site’s menu.
- Go to the “Scan” menu and start your first security scan.
- Wordfence Security will do a security scan of all files in your WordPress installation including those in the blogs.dir directory of your individual sites.
- Live Traffic will appear for ALL sites in your network. If you have a heavily trafficked system you may want to disable live traffic which will stop logging to the DB.
- Firewall rules and login rules apply to the WHOLE system. So if you fail a login on site1.example.com and site2.example.com it counts as 2 failures. Crawler traffic is counted between blogs, so if you hit three sites in the network, all the hits are totalled and that counts as the rate you’re accessing the system.
How does Wordfence Security protect sites from attackers?
The WordPress security plugin provides the best protection available for your website. Powered by the constantly updated Threat Defense Feed, WordFence Firewall stops you from getting hacked. Wordfence Scan leverages the same proprietary feed, alerting you quickly in the event your site is compromised. The Live Traffic view gives you real-time visibility into traffic and hack attempts on your website. A deep set of additional tools round out the most comprehensive WordPress security solution available.
How will I be alerted if my site has a security problem?
Wordfence Security sends security alerts via email. Once you install Wordfence Security, you will configure a list of email addresses where security alerts will be sent. When you receive a security alert, make sure you deal with it promptly to ensure your site stays secure.
Do I need a security plugin like Wordfence if I’m using a cloud based firewall (WAF)?
Wordfence provides true endpoint security for your WordPress website. Unlike cloud based firewalls, Wordfence executes within the WordPress environment, giving it knowledge like whether the user is signed in, their identity and what access level they have. Wordfence uses the user’s access level in more than 80% of the firewall rules it uses to protect WordPress websites. Learn more about the Cloud WAF identity problem here. Additionally, cloud based firewalls can be bypassed, leaving your site exposed to attackers. Because Wordfence is an integral part of the endpoint (your WordPress website), it can’t be bypassed. Learn more about the Cloud WAF bypass problem here. To fully protect the investment you’ve made in your website you need to employ a defense in depth approach to security. Wordfence takes this approach.
What differentiates Wordfence from other WordPress Security plugins?
- Wordfence security provides a WordPress Firewall developed specifically for WordPress and blocks attackers looking for vulnerabilities on your site. The Firewall is powered by our Threat Defense Feed which is continually updated as new threats emerge. Premium customers receive updates in real-time.
- Wordfence Security verifies your website source code integrity against the official WordPress repository and shows you the changes.
- Wordfence Security scans check all your files, comments and posts for URLs in Google’s Safe Browsing list. We are the only plugin to offer this very important security enhancement.
- Wordfence Security scans do not consume large amounts of your bandwidth because all security scans happen on your web server which makes them very fast.
- Wordfence Security fully supports WordPress Multi-Site which means you can security scan every blog in your Multi-Site installation with one click.
- Wordfence Security includes Two-Factor authentication, the most secure way to stop brute force attackers in their tracks.
- Wordfence Security fully supports IPv6 including giving you the ability to look up the location of IPv6 addresses, block IPv6 ranges, detect IPv6 country and do a whois lookup on IPv6 addresses and more.
Will Wordfence slow down my website?
No. Wordfence Security is extremely fast and uses techniques like caching its own configuration data to avoid database lookups and blocking malicious attacks that would slow down your site.
What if my site has already been hacked?
Wordfence Security is able to repair core files, themes and plugins on sites where security is already compromised. You can follow this guide on how to clean a hacked website using Wordfence. However, please note that site security can not be assured unless you do a full reinstall if your site has been hacked. We recommend you only use Wordfence Security to get your site into a running state in order to recover the data you need to do a full reinstall. If you need help repairing a hacked site, we offer an affordable, high-quality site cleaning service that includes a Premium key for a year.
Does Wordfence Security support IPv6?
Yes. We fully support IPv6 with all security functions including country blocking, range blocking, city lookup, whois lookup and all other security functions. If you are not running IPv6, Wordfence will work great on your site too. We are fully compatible with both IPv4 and IPv6 whether you run both or only one addressing scheme.
Does Wordfence Security support Multi-Site installations?
Yes. WordPress Multi-Site is fully supported. Using Wordfence Security you can scan every blog in your network for malware with one click. If one of your customers posts a page or post with a known malware URL that threatens your whole domain with being blacklisted by Google, we will alert you in the next scan.
What support options are available for Wordfence users?
Providing excellent customer service is very important to us. We offer help to all our customers whether you are using the Premium or free version of Wordfence Security. For help with the free version, you can post in our forum where we have dedicated staff responding to questions. If you need faster or more in-depth help, Premium customers can submit a support ticket to our Premium support team.

- Geshi the syntax highlighter now asks for more memory before running.
- Fixed bug that caused scan to hang on very large files.
- Added an index to wfStatus to make it faster for summary statuses
- Removed multisite pre-activation check to make activation more reliable on multisite installs.
- Better problem reporting if you trashed your Wordfence Security schema but the plugin is still installed.
- Removed use of nonces and purely using 30 minute key for unlocking emails.
- Fixed bug that caused admin emails to not get emailed when requesting unlocking email.
- Fixed minor issue with undefined array in issues loop.
- Added ability for admin’s to unlock login and unblock their IP addresses if they’re accidentally locked out by the firewall or login security. Uses two security tokens to prevent abuse.
- Admins can now also disable firewall and login security from the unlock-me email, just in case of emergency.
- Made advanced security options visible so you know they exist.
- Fixed dns_get_record() function not existing bug on Windows systems pre PHP 5.3.0. Was causing scans to hang.
- Increased login lockout defaults to be much higher which still protects against brute force hacks.
- Removed CURLOPT_MAXREDIRS in curl to avoid safe mode warnings.
- Fixed ability to view and diff files on blogs installed in subdirectories.
- Fixed ability to see individual IP hits on subdir sites.
- Plugin and theme update messages now include links to the upgrade page.
- Removed the link on the login form that mentions the site is protected by Wordfence Security.
- Changed lockout defaults to be much higher.
- Added options for higher number of failures before lockout in options page for configurable login security.
- Now including plugin version in the activity log when the admin chooses to email it to us for debugging.
- Admin can now select to scan outside the WordPress base dir and standard WordPress directories.
- Max memory size for scans is now configurable for larger installations. 256M is the default.
- Changed maximum scan time to 10 minutes.
- A harmless cosmetic error was being thrown up when some security scans started. Fixed that.
- Changed max scan time to 30 mins.
- Fixed a bug that caused scans to crash when permissions don’t allow a directory to be read.
- WP repo didn’t deploy the zip file correctly so recreating the version tag.
- Vastly improved error logging including catching fatal PHP errors and logging them to status log.
- Fixed accidental preg_replace variable interpolation.
- Syntax fixes (various)
- Increased memory available to Wordfence Security to 256M during security scans, configurable in wordfenceConstants.php
- Improved memory logging during security scans. Current memory usage is now shown on the far right of filenames while scans occur.
- Bugfix – fixed bug that caused Wordfence Security menu to dissapear.
- WordPress Multi-site support added. Currently in Beta. Tested with subdomains, not subdirectories, but it should work great on both.
- Main changes are moving menus to the Network Admin area, preventing individual blogs from enabling the plugin and dealing with database prefix issues.
- Improved diagnistic information on binary and regular API calls for better debugging.
- Changed ticker to only show activity with level < 3
- Email to send security alerts to is now configured at the same time an API key is entered.
- phpinfo is emailed along with activity log when user requests to send us activity log so that we can see things like PHP max execution time and other relevant data
- Now writing individual files to activity log during security scans for better diagnostics.
- Login security message.
- Updated readme.txt FAQ and description.
- Fixed bug where sites with self signed SSL security certificate never start scan because cert fails security check.
- Increased API curl timeout to 300 for slower hosts that seem affected during URL security scans.
- This is a major release of Wordfence Security, please upgrade immediately.
- Only scan files in the WordPress ABSPATH root directory and known WordPress subdirectories. Prevents potentially massive scans on hosts that have large dirs off their wordpress root.
- Don’t generate plain SHA hashes anymore because we don’t currently use them on the server side for scanning. (Still generates md5’s and SHAC)
- No longer do change tracking on files before scans because the change tracking does almost the same amount of work when generating hashes as the actual scan. So just do the scan, which is now faster.
- Updated internal version to 1.2 to use new code on the server side which sends back a list of unknown files rather than known files, which is usually smaller and more network efficient.
- Improved logging in activity log.
- Removed SSL peer verification because some hosts have bad cert config. Connection to our servers is still via SSL to enhance security.
- Fixed a few minor issues. Overall you should notice that scans are much faster now.
- Made real-time server polling more efficient.
- Entering your API key now automatically starts your first scan. Was causing some confusion.
- Reduced the number of database connections that Wordfence Security makes to one.
- Modified the memory efficient unbuffered queries we use to only use a single DB connection.
- Removed status updates during post and comment scans which prevents interference with unbuffered queries and makes the scans even faster.
- Fixed a bug where if you have the plugin “secure-wordpress” installed, you can’t do a Wordfence Security scan because it says you have the wrong version. This is because secure-wordpress trashes the $wp_version global variable to hide your version rather than using the filters provided by WordPress. So coded a workaround so that your Wordfence Security scans will work with that plugin installed.
- Minor fix to point to the correct binary API URL on the Wordfence Security cloud servers.
- It is now free to get a Wordfence Security API key.
- Premium keys include theme and plugin file security verification which consumes resources on the Wordfence Security servers.
- Various bugfixes and performance enhancements.
- Initial public release of Wordfence Security Plugin.
