Working securely with marketplaces using proxies

Modern marketplaces have turned into full-fledged ecosystems where sellers, buyers, logistics providers, and payment systems converge. For newcomers, marketplace work may look straightforward — “upload a product and receive orders” — but in reality it involves a complex set of processes: operating multiple accounts, automating uploads, gathering pricing data, integrating with 1C and CRM platforms, and preventing account bans. This is exactly where proxies become a critical component. 

Why security and data protection are so important 

Marketplaces are expanding rapidly and have become the primary engine of e-commerce in Russia. As transaction volumes grow and automation intensifies (automatic uploads, price parsing, mass updates), the likelihood of mistakes increases as well. Actions that are harmless when performed manually can easily trigger bans or data loss in automated workflows if platform limits are ignored. Marketplaces continuously improve their detection systems for bots, multi-account usage, and suspicious activity, so large volumes of requests from a single IP or abnormal behavior patterns quickly lead to penalties. 

The role of proxies in stable and secure marketplace operations 

Proxies are a foundational tool for safe interaction with marketplaces. 

• They conceal your real IP address, protect sensitive data, and distribute traffic across a large pool of IPs, reducing the risk of bans caused by excessive requests from one source. 

• Proxies make it possible to accurately simulate the behavior of users from specific regions, which is essential when testing advertising campaigns in target sales geographies. 

• When managing multiple accounts, proxies help isolate sessions, significantly lowering the probability of sanctions. 

• With proper setup, proxies also reduce the risk of targeted attacks on your infrastructure and prevent exposure of internal IP addresses. 

Main risks of working with marketplaces without proxies 

Account bans and temporary restrictions 

If all activity originates from a single IP, the marketplace will quickly detect signs of automation or multi-accounting. This can result in temporary blocks, permanent bans, verification requests, lost revenue, and time-consuming recovery processes. 

Account “linking” 

When several accounts are connected by the same IP or similar activity patterns, the platform may treat them as a single entity and apply penalties to all of them simultaneously. 

CAPTCHAs, rate limits, and automation breakdowns 

Without proper traffic distribution, request limits are reached much faster. The platform begins issuing CAPTCHAs or blocking requests entirely, disrupting automation. 

Incorrect regional insights 

Marketplace data varies by location. If all requests come from one region, you won’t see localized pricing, availability, or delivery options, which can lead to poor strategic decisions. 

Exposure to attacks and data leaks 

When internal systems operate without a proxy layer, they are easier to identify and attack. There is also an increased risk of accidentally exposing internal IPs or sensitive information due to misconfigured integrations. 

Distorted analytics and monitoring 

Collecting data from a single source skews analytics and market research. This results in an inaccurate understanding of competitors and demand, negatively impacting business strategy. 

How proxies help: how a proxy server works 

The core advantage of proxies lies in replacing and distributing traffic sources. Instead of all requests originating from one real IP, proxies assign different external IP addresses. This makes large-scale activity less noticeable and reduces the chance of restrictions being applied by the marketplace. 

The technical mechanisms behind this 

• IP substitution. A proxy replaces your external IP in network requests, so the marketplace sees the proxy’s address instead of your real one. 

• Headers and behavioral emulation. Proxies can add, modify, or remove HTTP headers to better imitate genuine browser behavior. 

• TLS/HTTPS tunneling. For secure connections, proxies establish encrypted tunnels. Data remains encrypted between you and the site, while the proxy still manages the channel and can enforce request limits. 

• Rotation and session control. Proxy pools support IP rotation based on time or session. “Sticky” sessions keep one IP for long-term account work, while rotation assigns a new IP to each request — ideal for large-scale data collection. 

Proxy types and their suitability for marketplace tasks 

Residential proxies 

These closely resemble traffic from real users. They are commonly used for multi-account management and scraping prices or reviews when reliability and credibility are crucial. 

Mobile proxies 

They offer the highest level of trust. IPs are often dynamic, and network behavior mirrors real mobile devices. This is the best choice for managing dozens of accounts, frequently switching locations, or accessing heavily moderated marketplaces from “mobile” sessions. They provide excellent masking but are also the most costly option. 

Datacenter proxies 

Well suited for high-volume scraping and one-time collection of large datasets. When you need to quickly gather thousands of pages or compile extensive price lists, datacenter proxies are efficient. However, they are not recommended for multi-account use, as marketplaces more easily flag this traffic as automated. 

Typical mistakes and how to prevent them 

Using free or low-quality proxies 

Many users try to cut costs on proxies, exposing the weakest point in their workflow. Such IPs are often already banned, unstable, and may disappear without notice. This leads to broken scripts, banned accounts, and wasted recovery time. 

Running multiple accounts through one IP 

Operating several stores or test profiles from a single address is a common cause of account “linking.” The marketplace quickly associates these profiles and may apply penalties. 

Ignoring marketplace behavior requirements 

Platforms monitor not only IP addresses but also activity patterns: update frequency, click behavior, and login times. Overly aggressive automation or actions that violate platform policies eventually result in blocks. 

No monitoring of connection stability 

Even high-quality proxies can occasionally fail or slow down. Without monitoring, automation may break silently. Clear logs showing errors, CAPTCHAs, or redirects help detect problems early and prevent revenue loss. 

Belurk was designed specifically to eliminate the issues that most often cause losses when working with marketplaces. The service provides multiple proxy types, speed monitoring, and transparent logging, so problems are visible immediately. Developers and automation engineers gain access to an API and straightforward integration with popular tools. And if questions arise, the support team helps select and configure proxies tailored to specific business tasks.
