Are you getting blocked by F5's strong anti-bot measures? This article will help you find a surefire solution to this problem.
But first, let's understand what F5 Cloud Bot Defense is and how its antibot works.
What Is F5 Cloud Bot Defense?
F5 Cloud Bot Defense is a security solution from F5 that uses AI and machine learning to analyze traffic patterns to detect and mitigate advanced bot attacks.
F5 Cloud Bot Defense can effectively differentiate between legitimate and illegitimate traffic that can make scraping challenging.
In 2020, F5 acquired Shape Security, another anti-bot and fraud detection technology leader. Shape's advanced detection and mitigation techniques are now integrated into F5's solutions, which provides a robust defense against automated threats.
How Does F5 Antibot Work?
F5 anti-bot uses multiple layers to catch bots. Here's how the F5 Distributed Cloud Bot Defense works:
- Signal Collection: The F5 anti-bot collects behavioral and environmental signals from the web and mobile apps.
- Real-time Bot Defense: The system processes signals in real time to identify humans, good bots, and bad bots. It works with many different networks and platforms liek application delivery networks and proxies, content delivery networks, application platforms, etc., to give wide protection.
- AI and ML-based Analysis: F5 uses AI and machine learning to study large amounts of data. This helps it adapt to new bot tricks. It updates its rules based on the data it collects.
- Connectors and Integration: The system connects with various platforms, such as Salesforce Commerce Cloud, Adobe Commerce, Amazon CloudFront CDN, Cloudflare, and more.
- Reporting and Telemetry: F5 has a dashboard to track bot activity. It sends telemetry data to improve how it finds and stops bots.
- Retooling Protection: The anti-bot system keeps improving its defenses based on AI insights and data analysis.
Despite the defenses, a few sophisticated techniques can bypass F5 anti-bot measures.
Method #1: Web Scraping API
A web scraping API is the easiest and most reliable method to bypass F5's anti-bot measures. This approach lets you focus on data extraction without worrying about complex anti-bot defenses.
ZenRows is a notable example of a web scraping API that excels in bypassing anti-bot systems like F5 and Shape Security. It offers features such as headless browsers, rotating premium proxies, optimized headers, and more, making it an ideal solution for web scraping without getting blocked.
To see if it works, let's try to access Nordstrom, a website protected by F5, using Selenium and Python:
# pip install selenium
from selenium import webdriver
import time
# configure Chrome driver for headless mode
options = webdriver.ChromeOptions()
options.add_argument('--headless=new')
# start a WebDriver instance
driver = webdriver.Chrome(options=options)
# visit the target page
driver.get('https://www.nordstrom.com/')
# wait for 5 seconds for the page to load
time.sleep(5)
# take a screenshot of the page
driver.save_screenshot('F5_blocked_screenshot.png')
# quit the driver
driver.quit()
F5 will block your request, and you'll get the following screenshot:
Let's now use ZenRows to bypass the F5-protected website.
Sign up to ZenRows, and you'll get redirected to the Request Builder page. Paste the Nordstrom URL in the link box, activate Premium Proxies, and toggle on JS Rendering boost mode. Choose Python as your programming language and select the API request mode.
Copy and paste the generated code into your script:
# pip3 install requests
import requests
url = 'https://www.nordstrom.com/'
apikey = '<YOUR_ZENROWS_API_KEY>'
# define your request parameters
params = {
'url': url,
'apikey': apikey,
'js_render': 'true',
'premium_proxy': 'true',
}
# send your request and print the HTML response
response = requests.get('https://api.zenrows.com/v1/', params=params)
print(response.text)
You'll get the following HTML output:
<html lang="en-us" xml:lang="en-us">
<head>
<!-- omitted for brevity -->
<title>Nordstrom Online & In Store: Shoes, Jewelry, Clothing, Makeup, Dresses</title>
<!-- omitted for brevity -->
<meta data-react-helmet="true" name="og:title"

<meta data-react-helmet="true" name="og:url" content="https://www.nordstrom.com/">
<meta data-react-helmet="true" name="og:description"

Congratulations! You've just bypassed F5 with ZenRows.
Method #2: Rotate Proxies
Proxies act as intermediaries between your scraper and the target website. They mask your IP address that makes it difficult for anti-bot systems to detect and block your requests.
Proxies can be static or rotating. However, static proxies can easily get banned if they exceed a particular request quota. Also, it's only a matter of time before the F5 antibot detects and blocks it.
On the other hand, rotating residential web scraping proxies allow you to distribute your requests across a diverse pool of IP addresses. This ensures that each request appears to come from a different user. It reduces the likelihood of your scraper being flagged for suspicious activity.

Method #3: Use Stealth Headless Browsers
Headless browser scraping is the process of using a browser that runs without a graphical user interface to automate data extraction from websites. This method allows scrapers to simulate user interactions, execute JavaScript, and navigate through web pages.
However, strong anti-bot solutions like F5 can detect and block them in no time. Headless browsers such as Selenium, Puppeteer, and Playwright contain obvious bot-like signals, e.g., specific user agent strings, predictable non-human navigation patterns, an automated WebDriver property, and more. Therefore, they can't bypass F5's security measures.
The popular headless browsers have stealth mode extensions to increase your chances of avoiding F5 detection during scraping. For example:
Still, headless browsers have significant downsides, such as high memory and resource consumption, complexity, and high maintenance costs.
Conclusion
You explored various methods to bypass F5 anti-bot protection, including using web scraping APIs, rotating proxies, and stealth headless browsers.
ZenRows web scraping API stands out as the best solution for bypassing F5. It offers a complete toolkit, including features like headless browser capabilities, rotating premium proxies, optimized headers, and more.
