How Secure is WordPress?

WordPress is a fairly secure CMS. Whenever a new vulnerability is discovered, WordPress provides patches and updates. Nevertheless, the use of third-party plugins and themes increases your chances of becoming vulnerable by providing additional routes of attack.

Why Use a Security Plugin in WordPress?

Unfortunately, many website owners are not concerned with their website’s security until their site has already been compromised. A website hack can damage your brand reputation, visitor trust, and SEO rankings.

If your WordPress website becomes compromised hackers may steal your sensitive data, distribute malicious code, or deface your website completely. Proactively installing a security plugin on your WordPress site can help prevent serious damage to your site and reputation.

A good WordPress security plugin protects your website from brute force attacks, hack attempts, and malware so that you can focus on building your brand and websites instead of worrying about security threats. Since cleaning a hacked WordPress website can be especially tedious and challenging, it’s better to take a proactive approach and avoid a compromise in the first place.

Adding a WordPress security plugin is a good starting point to securing your website. These all in one WP security plugins include a variety of key features such as malware scanning, web application firewalls and file-system integrity checks.

Website Security Plugin vs. Website Firewall

No website security plugin is able to handle distributed denial of service (DDoS) attacks. A DDoS attack is not only an application-kind-of-attack, it can also target the network itself, which is prior to the execution of a plugin. Even a simple SYN attack is enough to take a website down, even with security plugins installed.

The premium version of the Sucuri plugin is actually not a plugin, but the Sucuri website firewall that blocks malicious traffic before it reaches your website – including DDoS attacks. The Sucuri website firewall blocks around 40 millions attacks per day. It also includes a free CDN and DNS. These features speed up the website, whereas some other security plugins slow down the website as they are dependent upon server resources.

The Sucuri WAF is based on geographically diversified proprietary points of presence (PoPs) which operate and monitor the network 24/7 with redundancy on all levels. The Sucuri firewall helps your website become PCI compliant and updates daily via our team of expert researchers and engineers. Due to the general and platform-specific highly advanced filters, the Sucuri website firewall is able to block all types of exploits before they are even public. As well, it patches the entire network against a new vector in minutes with absolutely no interaction from the customer.

You can add website protection starting at $9.99 per website per month.
