Are residential proxies legal to use?

Residential proxies are not inherently illegal, but whether using them is legal depends on how you obtain them, where you are, and what you use them for.

Generally legal uses

• Privacy or IP rotation for ordinary web activity
• Price comparison or ad verification
• Testing websites from different locations
• Security research on systems you’re authorized to test

Potentially illegal or risky uses

• Scraping sites in violation of their terms, especially if it bypasses access controls
• Fraud, account abuse, credential stuffing, spam, or bot activity
• Hiding identity while committing other unlawful acts
• Using proxies that come from unwitting devices or consent is unclear, which can raise serious legal and ethical issues

Important caveats

• Terms of service violations can still get you banned or sued even if not criminal.
• Some countries have strict rules around cyber activity, interception, or unauthorized access.
• The legality can also depend on whether the proxy network is consensual and authorized.
