POWER CAPTCHA

<h4>STOP BOT AND HACKER ATTACKS</h4>
Safeguard your website’s forms and login areas from misuse, spam, and data theft caused by both bots AND hackers. POWER CAPTCHA uses customizable parameters to verify whether access is legitimate, either granting or denying access based on your chosen criteria.
<h4>MORE THAN JUST BOT PROTECTION</h4>
While many captchas only focus on stopping bots, they often fail to guard against unauthorized access by real users, such as someone repeatedly trying to guess login credentials or submitting forms multiple times. POWER CAPTCHA goes beyond traditional bot detection by evaluating all interactions, regardless of whether they’re human or automated. It uses flexible criteria — e.g. usernames, email addresses, IP addresses, and/or login attempts within specific timeframes — to assess if access is genuinely authorized.
Each interaction generates an encrypted code, or “client footprint”, which POWER CAPTCHA stores and analyzes. For future attempts, it can, for example, increase the challenge level or temporarily block further actions. With customizable settings based on your license, POWER CAPTCHA adapts to your specific security needs. You can also configure it as a no-captcha option.
<h4>GDPR-COMPLIANT, ACCESSIBLE, AND BUILT IN GERMANY</h4>
POWER CAPTCHA is cookie-free, GDPR-compliant, and easy to integrate with most systems. For added security and accessibility, the Enterprise Plan includes features like two-factor authentication.

PHPEnkoder is a port of the excellent <a href="http://hivelogic.com/enkoder" rel="nofollow ugc">Hivelogic 
Enkoder</a> to PHP and, more specifically, 
to WordPress. It is used to display text in a way that users can see 
and bots can’t.
The encoding system is directly and unabashedly stolen from the 
BSD-licensed source of Hivelogic Enkoder, which works by randomly 
encoding a piece of text and sending to the browser self-evaluating 
Javascript that will generate the original text. This works in two 
ways: first, a bot must first have a fairly complete Javascript 
implementation (in particular, it must have <code>eval</code>); second, the 
decoding process can be made arbitrarily computationally 
intensive. This is similar to the idea of charging computational 
payments to send e-mail, only this is actually implemented.
By default, PHPEnkoder scrambles e-mails in plaintext and in <code>mailto:</code> 
links. It additionally provides a shortcode for manual scrambling, 
used like so: <code>[enkode text="shown to non-JS browsers"]this will be 
scrambled[/enkode]</code>.

PHPEnkoder

Encodes mailto: links and e-mail addresses with JavaScript to stifle webcrawlers.  Automatically turns plaintext e-mails into (enkoded) links.
