Akamai Bot Manager represents one of the most sophisticated anti-bot systems protecting websites today. Its multi-layered detection mechanisms routinely block automated access attempts, making web scraping increasingly challenging.
Bypassing Akamai protection requires understanding its detection methods and implementing appropriate countermeasures.
This guide examines Akamai's security layers and provides practical technical solutions to navigate them effectively while maintaining ethical scraping practices.
How Akamai Detects and Blocks Bots
Akamai employs an advanced, multi-faceted approach to distinguish human visitors from automated bots. Understanding these detection vectors is crucial to developing effective bypass strategies.
IP Reputation and Analysis
Akamai maintains extensive databases tracking IP addresses across the internet. Datacenter IPs from cloud providers and proxy services are immediately suspicious, while residential IPs from legitimate ISPs receive higher trust scores.
Akamai automatically blocks IPs with histories of suspicious activity or those originating from geographical locations inconsistent with typical user patterns.
Even with clean IPs, excessive request rates trigger Akamai's rate limiting, resulting in HTTP 429 ("too many requests") errors .
TLS Fingerprinting (JA3)
During the TLS handshake process, Akamai analyzes client characteristics to create a unique JA3 fingerprint.
This fingerprint identifies client applications based on their TLS configuration, including cipher suites, extensions, and TLS versions.
Standard HTTP clients like Python's Requests and standard Node.js libraries have distinctive fingerprints that differ from major browsers.
Akamai blocks requests with fingerprints that don't match known browser profiles, making this one of the most challenging detection methods to bypass.
Behavioral Analysis
Akamai monitors user interaction patterns to detect automated behavior. Unlike humans, bots exhibit consistent interaction patterns such as identical scrolling behaviors, perfectly timed clicks, and predictable mouse movements.
The system also analyzes browsing sequences, noting whether users follow natural navigation paths or access pages in illogical orders.
These behavioral fingerprints allow Akamai to identify bots even when other bypass methods are successful.
JavaScript Challenge and Execution
Akamai frequently presents clients with cryptographic JavaScript challenges that must be executed successfully within a specified time frame.
These challenges create a "burden of proof" that separates browsers from simple HTTP clients.
Standard scraping tools like Python Requests cannot execute JavaScript, while automated browsers often fail because of detectable automation properties.
Successful challenge completion generates authentication cookies that must be included in subsequent requests.
Preparation: Detecting Akamai Protection
Before implementing bypass solutions, verify that a website uses Akamai protection.
Identifying Akamai Protection
- Check for Block Pages: Akamai blocks typically show "Access Denied," "Pardon Our Interruption," or reference numbers
- Examine HTTP Status Codes: Look for 403 Forbidden or 429 Too Many Requests errors
- Analyze Cookies: Akamai sets specific cookies like
_abckandbm_sz - Use Technology Detection: Browser extensions like Wappalyzer identify Akamai Bot Manager
Understanding the Block
Different block types require different solutions. Initial connection blocks indicate issues with IP reputation or TLS fingerprinting.
Post-request blocks suggest problems with session management or behavioral detection. JavaScript challenge failures require better browser automation or challenge-solving capabilities.
Technical Methods to Bypass Akamai
Method 1: Advanced Proxy Rotation Strategies
Residential proxies provide the foundation for effective Akamai bypass by masking your true origin with IP addresses from legitimate internet service providers.
Akamai's IP reputation systems heavily favor residential IPs over datacenter IPs.
# Advanced proxy rotation with Python
import requests
import random
from itertools import cycle
# Premium residential proxy list
proxies = [
"http://user:pass@proxy1.residential-provider.com:31112",
"http://user:pass@proxy2.residential-provider.com:31112",
"http://user:pass@proxy3.residential-provider.com:31112",
"http://user:pass@proxy4.residential-provider.com:31112",
"http://user:pass@proxy5.residential-provider.com:31112"
]
proxy_pool = cycle(proxies)
def make_request_with_rotation(url, headers):
proxy = next(proxy_pool)
try:
response = requests.get(url, headers=headers, proxies={"http": proxy, "https": proxy}, timeout=10)
return response
except requests.exceptions.RequestException:
# Rotate to next proxy on failure
return make_request_with_rotation(url, headers)
# Usage with proper headers
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36",
"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
"Accept-Language": "en-US,en;q=0.5",
"Accept-Encoding": "gzip, deflate, br",
"Connection": "keep-alive",
"Upgrade-Insecure-Requests": "1",
}Proxy Selection Criteria:
- Residential IPs from actual ISPs provide the highest success rates
- Mobile IPs from cellular networks offer excellent anonymity but higher costs
- ISP proxies blend datacenter reliability with residential IP characteristics
- Geographic targeting matching the website's expected user base
- Automatic rotation with each request or upon failure detection
Method 2: Use Fortified Headless Browsers
Standard browser automation tools like Selenium and Playwright are easily detected. Fortified browsers incorporate stealth modifications to evade detection.
# Example using SeleniumBase with Undetected ChromeDriver
from seleniumbase import Driver
driver = Driver(uc=True, headless=True)
url = "https://www.similarweb.com/"
# Reconnect to bypass initial detection
driver.uc_open_with_reconnect(url, reconnect_time=4)
page_html = driver.save_screenshot("similarweb.png")
driver.quit()
Stealth Modifications:
- Remove automation flags like
navigator.webdriver - Patch TLS fingerprints to match standard browsers
- Implement human-like behavior with random delays and interactions
- Modify browser properties to match genuine browser configurations
Effective tools include Playwright Stealth, Puppeteer Stealth, and SeleniumBase with Undetected ChromeDriver .
Method 3: TLS Fingerprint Spoofing
For non-browser scraping, spoofing TLS fingerprints is essential. The scrapy-impersonate library modifies Scrapy's TLS configuration to match real browsers.
# Scrapy with impersonation
custom_settings = {
"DOWNLOAD_HANDLERS": {
"http": "scrapy_impersonate.ImpersonateDownloadHandler",
"https": "scrapy_impersonate.ImpersonateDownloadHandler",
},
"TWISTED_REACTOR": "twisted.internet.asyncioreactor.AsyncioSelectorReactor",
}
# In your request
meta = {'impersonate': 'chrome110'}
This approach provides several advantages:
- Real browser TLS signatures without browser overhead
- HTTP/2 support matching modern browser capabilities
- JA3 fingerprint spoofing to bypass TLS-based detection
Method 4: Advanced Proxy Rotation
Residential proxies are essential for bypassing IP-based blocking.
# Premium proxy configuration with Playwright
from playwright.sync_api import sync_playwright
proxy_server = "http://premium_proxy:port"
proxy_username = "username"
proxy_password = "password"
with sync_playwright() as p:
browser = p.chromium.launch(
proxy={
"server": proxy_server,
"username": proxy_username,
"password": proxy_password
}
)
# Browser operations...
Proxy Selection Criteria:
- Residential IPs from actual ISPs
- Geographic targeting matching website expectations
- Automatic rotation with each request or failure
- Concurrent connection limits to avoid rate limiting
Advanced Techniques and Integration
Multi-Layer Bypass Strategy
Successful Akamai bypass typically requires combining multiple approaches:
- Initial Access: Use residential proxies with clean IP reputations
- Connection Phase: Spoof TLS fingerprints using specialized libraries
- Authentication: Execute JavaScript challenges with headless browsers
- Session Maintenance: Manage cookies and headers throughout the session
- Behavioral Mimicry: Implement human-like interaction patterns
Handling Specific Challenges
JavaScript Challenges:
# Using Playwright with stealth plugin
from playwright.sync_api import sync_playwright
from playwright_stealth import stealth_sync
with sync_playwright() as p:
browser = p.chromium.launch()
context = browser.new_context()
page = context.new_page()
stealth_sync(page)
page.goto("https://akamai-protected-site.com/")
content = page.content()
browser.close()
Cookie Management:
Maintain session cookies like _abck and bm_sz across requests . These cookies typically have limited lifetimes and must be refreshed periodically.
