A list of the best price monitoring tools in 2024.
Anti-bots are one of the significant challenges in web scraping. As anti-bot systems evolve, more advanced solutions are needed.
This article discusses some of the popular anti-bot services in the market. You can also read about various techniques to bypass these anti-bot measures.
What Are Anti-Bot Services?
Anti-bot services are systems or techniques that prevent bots (automated scripts) from scraping data from websites.
The anti-bots help the website administrators protect the site data, ensuring a better experience for human users.
Anti-bot services identify human users from bots using several methods, such as HTTP header validation, CAPTCHAs, and browser fingerprinting.
Are you aware of the various HTTP headers? If not, read our article on Essential HTTP Headers for Web Scraping.
What Are Some Popular Anti-Bot Services?
Anti-bots prevent bots that perform web scraping, spamming, or automated purchasing.
Mentioned below are some of the best bot detection tools that pose a threat to web scraping.
- Cloudflare Bot Management
- Akamai Bot Manager
- Imperva Bot Management (Formerly Distil Networks)
- PerimeterX Bot Defender
- reCAPTCHA
- Datadome Bot Management
- Kasada Bot Management
1. Cloudflare Bot Management
Cloudflare Bot Management detects and manages bot traffic based on machine learning, behavioral analysis, and fingerprinting technologies.
It offers a comprehensive set of tools that distinguish between human users and bots.
Cloudflare Bot Management also integrates well with Cloudflare’s CDN services and enhances the website’s performance and security.
2. Akamai Bot Manager
Akamai Bot Manager identifies and mitigates bots by analyzing behavior patterns and device fingerprinting.
Akamai’s global edge network and machine learning algorithms provide customized responses to different types of bot traffic.
It understands bot traffic patterns and ensures optimal website performance and user experience.
3. Imperva Bot Management (Formerly Distil Networks)
Imperva Bot Management (earlier Distil Networks) uses advanced algorithms to differentiate between bots and humans.
It uses fingerprinting and machine learning techniques to identify automated traffic and bot activity.
Imperva can offer real-time bot detection and provide comprehensive reporting and insights into bot traffic.
4. PerimeterX Bot Defender
PerimeterX Bot Defender identifies malicious bot activities using behavioral fingerprinting and advanced predictive analytics.
It can accurately detect and mitigate malicious bot traffic, providing real-time protection for web applications, APIs, and mobile apps.
PerimeterX Bot Defender offers detailed analytics and reporting for a deeper understanding of bot activity.
5. reCAPTCHA
reCAPTCHA is a CAPTCHA system developed by Google that can differentiate between humans and bots by presenting challenges.
These challenges are easy for humans to solve but difficult for bots. It protects websites from spam and abuse by asking users to complete various tasks.
reCAPTCHA also uses machine learning to improve its accuracy and effectiveness.
6. Datadome Bot Management
Datadome Bot Management provides real-time bot management and mitigation services.
It uses AI and machine learning to detect and block malicious bots on websites, mobile apps, and APIs.
It offers protection from automated threats such as scraping, credential stuffing, and Layer 7 (application layer) DDoS attacks.

7. Kasada Bot Management
Kasada Bot Management is an advanced anti-bot solution that can stop bots without needing historical data or extensive training periods.
It uses obfuscation and challenge-response mechanisms to make bot attacks costly and impractical.
Kasada provides real-time protection and enhances overall security and performance.
How Do You Bypass Bot Detection When Web Scraping?
To ensure web scraping without obstructions, you may need to bypass websites’ anti-bot measures.
Discussed are some practical methods to avoid detection and scrape websites without getting blocked.
1. Rotating User-Agents
To mimic the behavior of different browsers and devices, you can fake and rotate the user-agents regularly.
In most cases, it is harder for the anti-bot measures to recognize such patterns.
2. IP Rotation
IP rotation is another method that can bypass anti-bot techniques. Use multiple IP addresses to distribute requests.
Using these multiple IP addresses, you can prevent detection from rate-limiting mechanisms that block IPs with unusually high activity.
3. Headless Browsers
Headless browsers such as Puppeteer or Selenium can mimic natural human interactions.
These tools execute JavaScript and render pages similarly to a regular browser, reducing the chances of detection.

4. Behavioral Mimicking
Behavioral mimicking means simulating human-like behavior, such as implementing random delays and mouse movements or mimicking human click patterns.
Such mimicking sometimes avoids detection by making bot traffic appear more human-like. You can also mimic variable typing speeds and realistic browsing patterns.
5. CAPTCHA Solving Services
Use a third-party CAPTCHA-solving service or advanced optical character recognition (OCR) technology to solve CAPTCHAs.
Sometimes, the scraping script must employ human labor or automated solvers to bypass these anti-bot protections.
Wrapping Up
With the right strategies, you can overcome the complexity of anti-bot services. But even if you use sophisticated technologies, it can sometimes become a challenge.
If you need to extract large amounts of data, relying on an expert data service provider like ScrapeHero may be a solution.
ScrapeHero web scraping services are specifically tailored to overcome the challenges of anti-bot mechanisms.
Our expert team can bypass anti-bot protection, easily navigate the web, extract the data, and provide precisely what you need.
Frequently Asked Questions
1. What is anti-bot protection?
Anti-bot protection is the technique developed to detect, prevent, and mitigate automated bots from entering and extracting data from a website.
2. Does CAPTCHA stop bots?
Yes. CAPTCHA stops basic bots by presenting challenges like image solving, which is easy for humans but difficult for bots to solve.
