Working safely with marketplaces via proxies

Marketplaces have evolved into full ecosystems where buyers, sellers, logistics, and payments intersect. For a beginner, working with marketplaces may seem simple — “list a product and get an order” — but in practice it is a complex set of mechanisms and procedures: managing multiple accounts, automating data uploads, collecting pricing intelligence, integrating with 1C and CRM systems, and protecting against bans. And this is where proxies become indispensable.

Why security and data protection become critical

Marketplaces are growing rapidly and have become the main driver of e-commerce in Russia. As transaction volumes increase and automation scales (auto-uploads, price scraping, bulk updates), the risk of errors also rises. Actions that seem harmless when done manually can easily lead to account bans or data loss in automated mode if platform limits are not taken into account. Platforms continuously refine their algorithms for detecting bots, multi-accounting, and fraudulent activity, so mass requests from a single IP or atypical behavior patterns quickly become triggers for sanctions.

The role of proxies in ensuring safe and stable operations

Proxies are a key tool for secure work with marketplaces.

• They hide your real IP address, protect data, and allow traffic to be distributed across a wide pool of addresses, reducing the likelihood of bans caused by too many requests from a single IP.
• With proxies, you can correctly simulate the behavior of local users in specific regions, which helps when testing advertising campaigns in the geographies where you plan to sell.
• For managing multiple accounts, proxies allow you to separate sessions, lowering the risk of sanctions from the platform.
• With proper configuration, proxies also make it harder for attackers to target your infrastructure or obtain internal IP addresses.

Key risks of working with marketplaces without proxies

Account bans and temporary sanctions If all your interactions come from a single IP, the marketplace will quickly suspect automation or multi-accounting. The result can be a temporary or permanent ban, verification requests, lost sales, and time wasted on recovery.

Account “linking” When multiple accounts are “linked” by a single IP or similar behavior patterns, the platform may treat them as one issue and penalize all sellers at once.

CAPTCHA, rate limits, and automation failures Without traffic distribution, you will hit request frequency limits much faster. The system will start returning CAPTCHAs or blocking requests altogether.

Incorrect regional data Marketplaces display different information depending on the region. If all requests originate from one location, you won’t see the local picture and may make incorrect pricing or logistics decisions.

Vulnerability to attacks and data leaks If your internal systems are directly exposed to the network without a proxy layer, they are easier to discover and attack. There is also a risk of accidental leakage of internal IPs or sensitive data due to misconfigured integrations.

Problems with analytics and monitoring When data is collected from a single source, analytics and market research become distorted. You get an inaccurate picture of competitors and demand, which affects strategic decisions.

How proxies help: how a proxy server works

The main benefit of using proxies is changing and distributing the traffic source. Instead of everything coming from a single real IP, proxies substitute different external IP addresses. This reduces the likelihood that a marketplace will notice mass requests from one address and start applying restrictions.

What technical mechanisms are behind this

• IP substitution. A proxy replaces the external IP in network packets, so the request formally comes from the proxy’s address rather than your real one.

• Headers and behavior. A proxy can add or strip HTTP headers, helping to emulate the behavior of a real browser.

• TLS/HTTPS tunneling. For secure connections, a proxy establishes a tunnel: data is encrypted between you and the site, but the proxy still controls the channel and can limit request frequency.

• Rotation and sessions. Proxy pools support IP rotation by timer or by session. “Sticky” sessions keep the same IP for long-term account work; rotation provides a new IP for each request, which is convenient for large-scale scraping.

Types of proxies and their applicability for marketplace work

Residential proxies They look like requests from regular users. Used for managing multiple accounts and scraping reviews or prices when reliability is important.

Mobile proxies They provide a very high level of credibility. The addresses of such proxies are often dynamic, and network behavior resembles real smartphones. This is the best option when you need to work with dozens of accounts, frequently change geolocation, or log in from “mobile” sessions on heavily moderated platforms such as large marketplaces. They offer the best masking but are also the most expensive.

Datacenter proxies Ideal for large-scale scraping and one-time collection of big data volumes. If you need to quickly crawl thousands of pages or collect price lists for hundreds of products, server proxies are often optimal. However, using them for multi-accounting is risky, as platforms more easily recognize this traffic as automated.

Common mistakes and how to avoid them

Using free, unreliable proxies Many try to save on proxies and end up exposing the most vulnerable part of their workflow. Such IPs are often already blacklisted, unstable, and can disappear without warning. As a result, scripts break, accounts get banned, and you waste time on recovery.

Running multiple accounts through a single IP Launching several stores or test accounts from one external address is a classic cause of account “linking.” The platform sees the same network and quickly associates the profiles, which can lead to sanctions.

Ignoring marketplace activity requirements Marketplaces track not only IPs but also behavior: update frequency, click patterns, logins at unusual hours. If automation is too aggressive or contradicts platform rules, the account may eventually be blocked.

Lack of connection stability monitoring Even a good proxy can occasionally fail or degrade in speed — if you don’t notice this, automation will silently break. Logs should clearly show when errors, CAPTCHAs, or redirects start appearing, allowing you to react quickly and avoid losing sales.
