What is website security?

Website security is any action or application taken to ensure website data is not exposed to cybercriminals or to prevent exploitation of websites in any way.

Website security protects your website from:

  • DDoS attacks: These attacks can slow or crash your site entirely, making it inaccessible to visitors.

  • Malware: Short for "malicious software," malware is a very common threat used to steal sensitive customer data, distribute spam, allow cybercriminals to access your site, and more.

  • Blacklisting: Your site may be removed from search engine results and flagged with a warning that turns visitors away if search engines find malware.

  • Vulnerability exploits: Cybercriminals can access a site and data stored on it by exploiting weak areas in a site, like an outdated plugin.

  • Defacement: This attack replaces your website's content with a cybercriminal's malicious content.

Website security protects your visitors from:

  • Stolen Data: From email addresses to payment information, cybercriminals frequently go after visitor or customer data stored on a site.

  • Phishing Schemes: Phishing doesn't just happen in email. Some attacks take the form of web pages that look legitimate but are designed to trick the user into providing sensitive information.

  • Session Hijacking: Some cyberattacks can take over a user's session and force them to take unwanted actions on a site.

  • Malicious redirects: Certain attacks can redirect visitors from the site they intended to visit to a malicious website.

  • SEO Spam: Unusual links, pages, and comments can be put on a site to confuse your visitors and drive traffic to malicious websites.

Why do I need website security?

There are four main reasons why every website needs security.

  • Hosting providers protect the server your website is on, not the website itself. You can think of the website-host relationship like an apartment building: management provides security for the whole building, but it's up to each occupant to lock their door.

  • It's cheaper than a cyberattack. Cyberattacks can cost small businesses as much as $427 per minute of downtime by contrast, SiteLock customers pay an average of $1-2 per day for website security.

  • You'll protect your reputation and retain visitors and/or customers. Studies show that 65 percent of customers who have had their information stolen by a compromised website won't return to that site that's a devastating number of visitors to lose, especially for a small business or website.

  • Malware and cyberattacks can be hard to spot. Cybercriminals specialize in malware that can discreetly enter a site and stay hidden, so your website might be infected and you may not realize it. Some sneaky malware attacks include backdoors, a type of malware that allows cybercriminals to access a site without the owner's knowledge, and cryptojacking, which mines websites for cryptocurrency without showing any symptoms. These attacks are increasingly common: in Q2 2018, 43 percent of infected websites had at least one backdoor file, and cryptojacking continues to rise in popularity, doubling from Q1 to Q2 2018. Once cybercriminals secretly enter your website, they can access your data, steal traffic, deploy phishing schemes, and more, and you may never even notice.
