Updated on by in WordPress

If you are running a WordPress blog, security is something you should never ignore. I strongly suggest you spend some time considering the security aspect of you site, otherwise you are taking risk of all your efforts going down the drain. To keep your blog away from hackers, spams and malicious Internet agents, you have to make sure that you are always updated with the latest version of WordPress, and that’s the least thing you must do. You should also take serious steps toward your blog security by installing some plugins.


In today’s post, I would like to share with you 45 very effective security plugins to protect your WordPress blog. They’re each devised for different purposes, so you will get the best protection from each field. Remember, spending a few minutes on securing your blog can save you hours or even days of trouble later.


Akismet checks your comments against the Akismet web service to see if they look like spam or not and lets you review the spam it catches under your blog’s “Comments” admin screen.

This plugin lets users add CAPTCHA anti-spam methods to WordPress forms for comments, registration, lost password, login, or all. In order to post comments or register, users will have to type in the code shown on the image. This prevents spam from automated bots.

WP Security Scan
WP Security Scan checks your WordPress website or blog for security vulnerabilities and suggests corrective actions such as passwords, file permissions, database security, and more.

Secure WordPress
Secure WordPress beefs up the security of your WordPress installation by removing error information on login pages, adds index.html to plugin directories, hides the WordPress version and much more.

Bad Behavior
Bad Behavior complements other link spam solutions by acting as a gatekeeper, preventing spammers from ever delivering their junk, and in many cases, from ever reading your site in the first place. This keeps your site’s load down, makes your site logs cleaner, and can help prevent denial of service conditions caused by spammers.

This plugin integrates reCAPTCHA anti-spam methods with WordPress including comment, registration, and email spam protection.

Exploit Scanner
This plugin searches the files on your website, and the posts and comments tables of your database for anything suspicious. It also examines your list of active plugins for unusual filenames.

Role Scoper

Antispam Bee

Login LockDown
Login LockDown records the IP address and timestamp of every failed login attempt. If more than a certain number of attempts are detected within a short period of time from the same IP range, then the login function is disabled for all requests from that range. This helps to prevent brute force password discovery.

BulletProof Security
The BulletProof Security WordPress Security plugin is designed to be a fast, simple and one click security plugin to add .htaccess website security protection for your WordPress website. Activate .htaccess website security and .htaccess website under maintenance modes from within your WordPress Dashboard – no FTP required.

WP-Members is a plugin to make your WordPress blog a membership driven site. Perfect for newsletters, private blogs, premium content sites, and more! The plugin restricts selected WP content to be viewable by registered site members. Unlike other registration plugins and WordPress itself, it puts the registration process inline with your content instead of the native WP login page.

Limit Login Attempts
Limit Login Attempts blocks an Internet address from making further attempts after a specified limit on retries is reached, making a brute-force attack difficult or impossible.

NoSpamNX automatically adds additional form fields to your comment form, invisible to human users. If a spambot fills these fields blindly (which most of all spambots do), the comment will not be saved. You can decide if you want to block these spambots or mark them as spam.

AskApache Password Protect
This plugin doesn’t control WordPress or mess with your database, instead it utilizes fast, tried-and-true built-in security features to add multiple layers of security to your blog. This plugin is specifically designed and regularly updated specifically to stop automated and unskilled attackers attempts to exploit vulnerabilities on your blog resulting in a hacked site.

TAC (Theme Authenticity Checker)
TAC stands for Theme Authenticity Checker. Currently, TAC searches the source files of every installed theme for signs of malicious code. If such code is found, TAC displays the path to the theme file, the line number, and a small snippet of the suspect code.

Math Comment Spam Protection

Better WP Security
Better WP Security takes the best WordPress security features and techniques and combines them in a single plugin thereby ensuring that as many security holes as possible are patched without having to worry about conflicting features or the possibility of missing anything on your site.

Semisecure Login Reimagined
Semisecure Login Reimagined increases the security of the login process by using a combination of public and secret-key encryption to encrypt the password on the client-side when a user logs in. JavaScript is required to enable encryption. It is most useful for situations where SSL is not available, but the administrator wishes to have some additional security measures in place without sacrificing convenience.

Admin SSL
Admin SSL secures login page, admin area, posts, pages – whatever you want – using Private SSL. Once you have activated the plugin, go to the Admin SSL config page to enable SSL, and read the installation instructions.

User Locker
This plugin closes security holes by introducing maximum number of invalid login attempts. When someone exceeds this number, his/her account becomes locked, and can be unlocked only by requesting new password (using Lost Password option) or asking Admin for help. This makes brute force and dictionary attacks nearly impossible.

Doing so will protect you from hackers looking to exploit this particular vulnerability.
