Alternate Bot Protection Options

1. reCAPTCHA v3

Unlike reCAPTCHA v2, reCAPTCHA v3 operates in the background without requiring any user interaction.

It assigns a score to each user based on their behaviour, allowing you to implement bot protection without interrupting the user experience.

This makes it a seamless option for form protection, but it may not be suitable if you require explicit user verification.

2. hCaptcha

hCaptcha is a privacy-focused alternative to reCAPTCHA that aims to provide a more user-friendly and privacy-conscious bot protection solution.

It offers a range of challenges, including image recognition, audio challenges, and more.

With hCaptcha, you can customise the appearance to match your website’s design, making it a good choice for enhancing the user experience.

3. Custom CAPTCHA Solutions

Building a custom CAPTCHA solution gives you full control over the challenge’s design and implementation.

This allows you to create unique and tailored bot protection mechanisms for your HTML forms.

However, developing a custom CAPTCHA can be time-consuming and may require expertise in web development and security.

4. Bot Filtering and IP Blocking

Implementing bot filtering techniques and IP blocking can help prevent automated submissions.

By analysing user behaviour, IP addresses, and other factors, you can identify and block suspicious or malicious activity.

While this approach can be effective, it may require ongoing monitoring and adjustments to maintain an optimal balance between security and false positives.

5. Hidden Fields and Time-Based Techniques

Incorporating hidden form fields that are invisible to users can help identify bot submissions.

Bots tend to fill out all fields, including hidden ones, while humans typically leave them blank.

Time-based techniques, such as form submission rate limiting, can also be effective in detecting and blocking automated submissions.

6. Behavioural Analysis

Leveraging behavioural analysis tools and techniques can help differentiate between human and bot interactions.

By analysing mouse movement, keystrokes, and other behavioural patterns, you can detect and block suspicious activity.

This approach requires additional integration and may involve a learning period to fine-tune the system.

7. Two-Factor Authentication (2FA)

Adding a second layer of authentication, such as SMS verification or email confirmation, can enhance bot protection.

Users must complete the additional verification step before their form submission is accepted.

However, implementing 2FA adds complexity and may introduce friction in the user experience.

Conclusion

Remember that no solution is completely foolproof, and the best approach often involves a combination of techniques.

Consider your specific requirements, user experience goals, and level of protection needed when selecting an alternative bot protection solution for your HTML forms.
