  • Astra Web Security

    Best for: Powerful features
  • Wordfence Security

    Best for: Real-time protection

In a world in which hackers compete for how many websites they manage to break it is essential to think about security measures, now more than ever. WordPress as a platform offers probably the most secure environment among content management systems, but to make things even safer, we offer you top security plugins to keep the bad guys away from your site.

Tips for a secured WordPress website

Always update your WordPress site / themes and plugins to the newest version available

As I said earlier, WordPress is a well coded platform that offers security measures perfected by top developers in the world. WordPress as a CMS has the advantage of being the most popular platform which comes as both a blessing and a curse. The fact that is popular makes it a more common ground for hackers but also this means it's greater because has a larger team of developers involved, people who work 24/7 to bring the cutting-edge / flawless security solution that you know today.

My recommendation is to check for updates in the WordPress dashboard as frequently as possible and whenever you see a new update, just install it.

Never install untrusted plugins

The internet is full of "so called" developers who offer plugins and themes. Their only interest is to gain access to your WordPress website and exploit all possible vulnerabilities. These can turn into ransomware, malware, keyloggers and every possible form of unwanted intrusion.

Stay away from nulled plugins and themes

You'll see that every popular premium plugin and theme out there has a fake version tricked by hackers to work for free. These versions may indeed work, but you should know that they will always come alongside unwanted code in your WordPress website. Usually hackers manage to infiltrate bad code in your site using the "php injection" method or simply by generating new files on your server.

If an offer looks too good to be true, then stay away because it probably is. We recommend you to only install plugins and themes from authorized / trusted developers and the official WordPress repository.
