Proxy traffic

What is proxy traffic ?

Proxy traffic refers to website visits that pass through a proxy server instead of connecting directly from the user’s original IP address. Proxies act as intermediaries between the user and the web server, masking the true identity and location of the visitor.

While proxies have legitimate purposes such as :

• Improving performance

• Bypassing geo-restrictions

• Maintaining privacy

They are also frequently misused by :

• Bots and scrapers

• Hackers

• Competitors

• Fraudulent users

How do proxies work ?

A proxy server acts as a gateway between an end-user and the website they’re accessing. It :

• Hides the original IP address

• Replaces it with the proxy’s IP

• Routes the request to the destination server

Types of Proxies :

• Anonymous proxies : Hide the original IP

• Rotating proxies : Frequently change IPs to evade detection

• Residential proxies : Mimic real users for stealth

• Datacenter proxies : Mass-used by scrapers and botnets

Why is proxy traffic dangerous ?

Proxies are commonly used by bad actors to disguise their identity and bypass detection systems. Typical threats include :

• Web scraping of sensitive content, pricing, or SEO data

• Credential stuffing using leaked login credentials

• DDoS attacks originating from proxy chains

• Competitive spying without IP traceability

• Fake account creation, spam submissions, or checkout fraud

Because proxies bypass traditional geolocation and IP-based filtering, basic firewalls alone are not enough to block malicious traffic.

How to detect proxy traffic

Detecting proxy traffic requires combining multiple methods :

• IP reputation scoring

• Behavioral analysis (click speed, session patterns)

• Traffic fingerprinting

• ASN (Autonomous System Number) monitoring

• Known proxy IP range detection

Indicators of suspicious proxy traffic include :

• Sudden spikes from datacenter IPs

• Sessions with unnatural navigation speed

• High bounce rates or spam form submissions

• Abnormal API usage or rate-limiting abuse

How to block proxy traffic effectively

Effective proxy traffic protection requires real-time threat detection combined with intelligent filtering. Best practices include :

• Blocking known proxy IPs (from proxy lists or free tools)

• Using IP reputation systems to assess risk

• Detecting and blocking rotating/residential proxies

• Monitoring for automation tools disguised as browsers
