Not implementing CAPTCHA: major cyber risks
See why it is important to implement a CAPTCHA system on your website.
The CAPTCHA system: filters automated traffic and ensures that interactions with the system come from real human users and not bots.
Failing to implement bot-protection mechanisms, such as CAPTCHA, presents several cyber risks, including:
- Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks:
Without mechanisms such as CAPTCHA, an attacker can use bots to send a large number of requests to the server, overloading it and causing service unavailability for legitimate users.
2. Fraud and account abuse:
Bots can be used to create fake accounts en masse, post spam comments, send phishing messages or execute fraudulent transactions. This can damage the platform’s reputation and affect the experience of legitimate users.
3. Resource abuse:
Bots can consume a site’s or application’s resources, which can lead to excessive consumption of bandwidth, processing power and storage, affecting the overall performance of the system.

4. Data extraction (scraping):
Without protection, bots can automatically access and copy valuable information from the site, such as customer contact details, product prices, original content, etc. This can lead to financial losses and reduced competitiveness.
5. Security breaches:
Bots can probe and exploit a system’s security vulnerabilities to gain unauthorised access to sensitive data or to compromise the integrity of the system.
6. Compromising the authenticity of interactions:
Without CAPTCHA, it is difficult to distinguish between legitimate and automated interactions, which can affect the quality and relevance of the data collected about users.
