Penetration testing and vulnerability scanning require requests from diverse IP addresses to assess how a target responds to traffic from different sources. Datacenter proxies provide the low latency and high throughput that security scanning demands.
Use datacenter proxies for cybersecurity testing. Security scanning needs low latency and high request throughput -- datacenter proxies deliver both at a fraction of residential cost. Use residential only when testing from consumer IP perspectives.
| Latency | ~3ms median on datacenter exits |
| Throughput | Unlimited concurrency for parallel scans |
| IP diversity | Diverse ASNs for source-IP testing |
| Cost fit | From $0.02/IP datacenter |

You MUST have a written scope agreement with the target owner before scanning. Unauthorized scanning is illegal regardless of the IP source. Document your authorization and testing scope before starting.
WAFs and security systems respond differently to datacenter, residential, and mobile traffic. A thorough security assessment tests how the target handles requests from each IP type, from multiple geographic origins, and at various request rates. Proxies provide the diverse source IPs that simulate real-world attack patterns.
The only reliable way to see what a real user sees is to become one.
Scheduler, proxy fetch, parser, store -- the proxy is one line in the fetch step. Everything else is pipeline you already run.
Before any scan, obtain a signed scope agreement from the target owner. Document the IP ranges, ports, and test types authorized. Keep this on file.
Datacenter proxies provide the speed and concurrency needed for scanning. Use residential only when you need to test how defenses respond to consumer traffic.
A complete assessment tests the target from datacenter, residential, and mobile sources. Each IP type may trigger different WAF rules, revealing configuration gaps.
Failed fetches are never billed, so your effective cost tracks the success rate you actually observe.
Absolutely. You must have a written scope agreement with the target owner before any scanning. Unauthorized penetration testing is illegal regardless of what proxy you use.
Security scanning needs low latency (~3ms) and high throughput for port scanning and vulnerability checks. Datacenter proxies deliver both at $0.02/IP. Use residential only when testing consumer-facing defense behavior.
Yes. KnoxProxy datacenter proxies are available across multiple regions, letting you test how targets respond to traffic from different origins -- which reveals geo-based WAF rules.
Bug bounty targets with published scope are authorized by definition. Use datacenter proxies for the scanning phase and document your source IPs in your bug bounty report.
