Do I Need a WordPress Security Plugin?

Usually all CMS or should I say, all online interfaces are built strong and secure. However, with time, hackers find loopholes that decrease the security of your WordPress site. 

Now you would be thinking, that you understand that, however, why would someone attack your website? So, here is the thing. It’s not always necessary that an attack on your website is always dangerous. 

It can be as simple as a malware injection to redirect users to a different site, inserting ads, slowing down your website, etc. 

It can also be dangerous especially if you keep confidential data on your website, like your client’s name, address, and contact, payment details, or other such records and documentation.

There are a few reasons that will answer the question that whether you need a WordPress security plugin:

  • To prevent brute attacks where a combination of passwords is used to log in to your WordPress account. This allows hacker’s full control of your website.
  • To prevent payment data from being stolen, SQL injection, cross-site scripting, etc. by automated or manual attacks with the help of security vulnerabilities on your website. 
  • If you are a developer and have full access to your server then you can build a firewall for your site.

In most cases, this kind of access is not available and not everyone has the technical knowledge to build a firewall. In such instances, a security plugin is what will come in handy.

Being the first line of defense, a firewall allows or blocks certain unwanted traffic from connecting to your website. 

If you’re still not too sure, read the article further to understand if the WordPress security plugins are really meant for you. 

Why One Should Use a WordPress Security Plugin?
