Residential proxies route your requests through real consumer IP addresses so you can view the web the way ordinary users in a given city or state do. That capability powers many everyday business workflows — but the same tool can be misused. This guide explains the use cases we support, why they are legitimate, and the bright line we will not cross.
Legitimate proxy use cases at a glance
| Use case | What it involves | Why it's legitimate |
|---|---|---|
| E-commerce & price monitoring | Checking public product prices and stock across regions | Competitive pricing is a normal business activity using public data |
| Market research | Gathering public sentiment, listings, and trends | Aggregating openly available information for analysis |
| Ad verification | Confirming your ads render correctly and aren't near bad placements | Advertisers have a right to audit their own campaigns |
| SEO monitoring | Checking search rankings and localized results | Understanding your own visibility across locations |
| Public web-data collection | Lawfully gathering openly published data | No login or paywall is bypassed; terms are respected |
| Brand protection | Detecting counterfeits, scams, and trademark misuse | Protecting your own IP and customers |
| Authorized account management | Managing your own or clients' accounts with permission | Legitimate operations you are authorized to perform |
Price monitoring and e-commerce
Retailers and brands track competitor pricing, promotions, and availability to stay competitive. Because prices are often localized, viewing them from the right city or state gives an accurate picture. This uses publicly displayed information and is a standard part of retail analytics.
Market research
Businesses study public listings, reviews, and trends to understand demand. Seeing region-specific content — a restaurant directory in one state versus another — helps build accurate datasets. The key principle: gather only what is publicly available and respect each site's terms.
Ad verification
Advertisers spend real budgets and deserve to know their ads appear correctly, in the right geography, and away from harmful content. Residential IPs let verification partners see the live ad experience a genuine local user would, catching misrenders, fraud, and policy violations.
SEO and localized search monitoring
Search results differ by location. Marketers check how their own pages rank in different cities to measure visibility and plan content. This is observation of public search results, not manipulation of them.
Lawful public web-data collection
Collecting openly published data — for research, pricing intelligence, or analytics — is legitimate when you do not bypass logins or paywalls, do not overload servers, and honor robots directives and terms of service. When in doubt, prefer official APIs and rate-limit your requests.
Brand protection
Brands use proxies to find counterfeit listings, phishing clones, and trademark misuse across regions, then act through proper channels. Protecting your own intellectual property and customers is a clearly legitimate goal.
What proxy use is not allowed
The line is simple: if an activity is illegal, deceptive, or violates a site's terms, it is prohibited. That includes:
- Spam, unsolicited messaging, and bulk fake-account creation
- Credential stuffing, account takeover, or unauthorized access
- Fraud, carding, payment abuse, or identity theft
- Phishing, malware distribution, or command-and-control traffic
- Denial-of-service attacks or any attempt to disrupt infrastructure
- Bypassing paywalls, logins, or access controls you are not entitled to use
- Harassment, exploitation, or any other illegal activity
We reject framing built around being "undetectable" or evading enforcement. Proxies are a tool for legitimate visibility, not for hiding wrongdoing. Nefo's Acceptable Use Policy governs every account, and violations can lead to suspension.
Key takeaways
- Residential proxies are legitimate for lawful, transparent, public-data tasks.
- Always respect each website's terms of service and applicable law.
- Prefer official APIs, reasonable request rates, and public data only.
- Prohibited use — fraud, spam, attacks, unauthorized access — is never acceptable.
- Review the Nefo AUP before you start, and check pricing to size your plan.
