Sx.org review: A closer look at its global proxy network

Sx.org positions itself as a proxy marketplace, bringing residential, mobile, and corporate proxies together under one platform, with 12M+ IPs across 235 countries, flexible GEO targeting, and multiple rotation options. But a large proxy network does not always guarantee consistent quality and performance. 

In this Sx.org review, IPFighter examines its proxy types, features, pricing, and real-world performance to see how well the network performs in practice.

2. Proxy types available at Sx.org

Sx.org currently offers three main proxy categories: residential, mobile, and corporate proxies. Each is positioned for different workloads, from account management and GEO-sensitive tasks to large-scale data collection.

2.1. Residential proxies

Sx.org's residential proxies use IP addresses associated with home internet connections and are designed to resemble regular user traffic.

• Advertised proxy pool: 7 million IPs

• Session: Unlimited IP change

• Filtering: Country, region, city, ASN targeting

• Rotation: Rotating and sticky sessions

• Protocols: HTTP(S), SOCKS5

Overall, the residential proxy package offers flexible session and targeting options, making it suitable for workflows that require specific locations or control over how often the IP changes.

2.2. Mobile proxies

Mobile proxies route traffic through IP addresses associated with real mobile devices and carrier networks.

• Advertised proxy pool: 4 million IPs

• Connection: Backconnect architecture

• Filtering: Country, region, city, ASN targeting

• Rotation: Rotating and sticky sessions

• Protocols: HTTP(S), SOCKS5

Sx.org also states that its mobile infrastructure uses real 4G modems connected to real SIM cards rather than emulated mobile environments.

2.3. Corporate proxies

Corporate proxies, which Sx.org describes as server-hosted proxies, are designed primarily for speed, large-scale traffic, and automation.

• Advertised proxy pool: 1 million IPs

• Connection: Backconnect architecture. 

• Filtering: Country, region, city, ASN targeting

• Rotation: Rotating and sticky sessions

• Protocols: HTTP(S), SOCKS5

Overall, the three proxy types give users a choice between higher-trust residential and mobile connections and speed-focused corporate infrastructure.

3. Key features of Sx.org proxies

Beyond its proxy types, Sx.org provides several features designed to give users greater control over proxy selection, sessions, and traffic management.

• Country, region, city, and ASN targeting: Select proxies based on specific geographic locations and ISP for more precise GEO targeting.

• Flexible IP rotation: Choose timer-based rotation, per-request rotation, sticky connections, or a break-connection mode depending on the workflow.

• Unlimited proxy ports: Sx.org states that users can create unlimited ports and run multiple threads, sessions, and connections without technical limits on proxy usage.

• API integration: Developers can create, update, delete, refresh, and manage proxy ports through the Sx.org API. The API documentation also provides examples for Java, Node.js, PHP, and Python, etc.

• Traffic analytics: The dashboard provides debit history and traffic consumption statistics, allowing users to monitor usage by day, month, or overall account activity.

These features make Sx.org more than a basic proxy seller, particularly for users who need GEO control, flexible rotation, and centralized proxy management.

4. Sx.org pricing overview

Sx.org uses two main pricing models: pay-per-traffic and unlimited proxies. The current homepage lists the following starting prices.

The pay-per-traffic model is designed for users who want flexibility and only want to pay for the traffic they actually use. In contrast, the unlimited proxy plans are better suited for users with stable, high-volume needs, offering fixed access without worrying about traffic limits or overage costs.

For unlimited plans, volume discounts are available: 5% from 10 proxies, 10% from 50 proxies, and 15% from 100 proxies.

5. Performance test

To evaluate Sx.org beyond its published specifications, IPFighter's testing process focuses on three key areas: IP quality, connection performance, and geolocation accuracy. We tested a proxy taken from the Pay-per-traffic tariff using IPFighter, Speedtest, and Google Search package.

5.1. Preparation

Before evaluating the proxy, we first added it to our browser using the IPFighter Proxy Manager extension. This extension makes it easy to import, manage, and switch between multiple proxies directly within your browser, eliminating the need for manual proxy configuration.

5.2. Test results

First, regarding the test results from IPFighter, the tested IP addresses achieved an overall score of 85% IP score, with platform scores ranging from 77% to 92%. Instagram scored highest at 92%, followed by Youtube at 91%, Facebook at 90%, and Google at 86%. Overall, all platforms rate these IP addresses as highly reputable, indicating a strong standing and suitability for tasks involving leading social media platforms and search engines.

IP scores on major platforms

The IP lookup identifies the address as a U.S. IPv4 residential IP located in Destin, Florida, and associated with Cox Communications Inc. It is classified as a Residential ISP, while the check detected no proxy, VPN, or datacenter IP and showed a Clean threat blacklist status, suggesting a genuine residential connection with no major risk flags. The IP also received a 90% reputation score, categorized as Good reputation, indicating that it appears trustworthy to online platforms and anti-fraud systems.

Next, a speed check is performed on Speedtest for this proxy from Sx.org's Pay-per-traffic plan. The results show 3.49 Mbps download and 3.50 Mbps upload, which is quite modest for a residential proxy. During testing, this bandwidth is sufficient for basic tasks like light web browsing, text searching, or account management, but may struggle with high-definition streaming or heavy file downloads.

The measured ping was around 511 ms, which is high and may cause noticeable latency during real-time interactions. Overall, for a randomly selected IP from this tariff, the performance is basic but still functional for light, low-bandwidth MMO tasks.

Finally, a location check was conducted via Google search, which detected the location as Destin, Florida, US. Because the proxy was set to target Florida, US, this result directly matches both the initial setup and the location identified by IPFighter (Florida, US). This indicates strong geolocation consistency across different detection services at the state level.

Check on the Google search bar

These results are based on randomly selected IPs during the testing process, so actual performance may vary depending on the specific IP, geographic location, network conditions, and time of use. Therefore, individual IPs may deliver different speeds, latency, and geolocation results in real-world use.

8. Conclusion

Overall, Sx.org is worth considering if you need residential or mobile proxies with high IP cleanliness, zero proxy detection flags, and accurate geolocation targeting. While connection speeds on the Pay-per-traffic plan remain basic, its non-expiring bandwidth options and massive pool of over 12 million IPs offer great flexibility for risk-sensitive tasks like account management and scraping.

Please note that these test results are based on a randomly selected IP at a specific time, so actual performance may vary depending on the individual IP, location, network conditions, and time of use.
