CAPTCHA technology helps protect websites by making sure that only real people, not automated bots, can access certain areas.
It does this by asking users to complete simple tasks, like solving puzzles or typing letters.
This helps keep websites safe from cyber-attacks and harmful automated actions.
Let us understand how it prevents automated cyber-attacks in the words of designers and developers of the best web design agency in Delhi –
Human Differentiation
CAPTCHA helps websites know if a user is human or a bot. Bots are like robots that can harm websites. They try to do things quickly and automatically.
But CAPTCHA stops them. It shows puzzles or tasks that only humans can solve. For example, a person may need to pick out pictures or type wavy letters. A bot cannot do these tasks easily.
So, when someone solves the CAPTCHA, the website knows they are real. This keeps the website safe from bots. It makes sure only real users can continue, while stopping automated attacks. This helps protect online services.
Prevents Brute Force Attacks
Bots sometimes try to guess passwords many times to break into accounts. This is called a brute force attack. They keep trying different passwords until they find the right one.
CAPTCHA helps stop this. When a person tries to log in, CAPTCHA gives a puzzle. Only humans can solve these puzzles, not bots. The bot gets stuck because it cannot answer.
So, the attack is stopped. CAPTCHA makes sure only real people can keep trying to log in. This protects accounts from being hacked by bots that guess passwords again and again.
Blocks Spam Submissions
Some bots try to fill out forms on websites automatically. They send spam or fake messages quickly. CAPTCHA helps stop this. When someone wants to fill out a form, CAPTCHA shows a small task.
The task could be picking pictures or typing letters. A bot cannot do these tasks. So, the bot cannot send spam or fake messages. Only real people can complete the form because they can solve the CAPTCHA.
This keeps the website safe from getting too many fake or spam submissions. CAPTCHA protects the website from bots trying to fill out forms automatically.
Prevents Web Scraping

Prevents Ticket Scalping

CAPTCHA helps stop this problem. When someone tries to buy tickets, CAPTCHA shows a puzzle. The puzzle can be picking certain pictures or typing letters. A bot cannot solve these tasks easily.
So, when a bot tries to buy tickets, it gets stuck. Only real people can complete the CAPTCHA and buy the tickets. This keeps tickets available for actual fans and protects fair ticket sales.
Secures Online Polls and Surveys
Bots can take part in online polls and surveys. They can vote many times to change the results. This is unfair and can make the results wrong. CAPTCHA helps prevent this from happening.
When someone wants to vote or answer a survey, CAPTCHA gives a small task. It could be choosing pictures or typing letters. A bot cannot complete these tasks. So, when a bot tries to vote, it gets stopped.

Reduces DDoS Attacks
Bots can attack websites by sending a lot of fake traffic. This is called a DDoS attack. The goal is to overload the website and make it crash. CAPTCHA helps stop this from happening.
When many requests come to a website, CAPTCHA can be added to check if they are real. It shows puzzles that only humans can solve. Bots cannot answer these puzzles. So, when the bots try to attack, they get stuck.
This protects the website from crashing and keeps it running smoothly. CAPTCHA ensures that only real users can access the website, stopping automated attacks.
Mitigates Ad Fraud
