How to Block VPN Traffic on Your Shopify Store

Why Stores Block VPN Traffic

VPN (Virtual Private Network) services allow users to mask their real IP address and appear to be browsing from a different location. While VPNs have many legitimate uses for personal privacy and security, they are also heavily used to circumvent store protections. Understanding why store owners block VPN traffic will help you decide whether it is the right choice for your business.

Fraud Prevention

VPN usage is one of the strongest signals associated with online fraud. Fraudsters use VPNs to hide their real location when making purchases with stolen credit cards. By masking their IP, they make it harder for fraud detection systems to match the buyer’s location with the billing address or flag suspicious geographic patterns. Studies consistently show that orders placed through VPNs have a significantly higher chargeback rate than orders from direct connections.

Promotional Abuse

If you run region-specific promotions, discount codes, or sales, VPN users can exploit them by appearing to be in the qualifying region when they are not. For example, a promotion offering free shipping within the United States can be abused by international users connecting through a US-based VPN server. Similarly, new-customer discounts can be repeatedly claimed by the same person using different VPN exit points.

Geographic Restriction Enforcement

Many stores restrict access based on geography for legal, licensing, or logistical reasons. If you only ship to certain countries or are required to comply with regional regulations, VPNs allow visitors to bypass these controls. A visitor in a restricted country can use a VPN to appear as though they are in a permitted region, place an order, and create fulfillment complications.

Bot and Scraper Protection

Automated bots and scrapers routinely use VPN and proxy networks to rotate their IP addresses and avoid detection. Blocking VPN traffic eliminates a major tool in the bot operator’s toolkit, making your store harder to scrape and your product drops harder for bots to target.

Price Discrimination Circumvention

If you use Shopify Markets or other tools to set different prices by region, VPN users can shop around for the lowest price by changing their apparent location. This undermines your pricing strategy and can result in orders at prices not intended for the buyer’s actual market.

How VPN Detection Works

SecurEcommerce identifies VPN traffic using multiple detection methods that work together for high accuracy.

IP Database Matching

The primary method is matching visitor IP addresses against databases of known VPN, proxy, and TOR exit node IPs. These databases are maintained by specialized intelligence providers and are updated continuously as VPN providers add and rotate servers. SecurEcommerce uses multiple databases to maximize coverage.

Traffic Pattern Analysis

VPN connections often have detectable characteristics. The network latency patterns, packet timing, and connection behavior of VPN-tunneled traffic differ subtly from direct connections. SecurEcommerce’s analysis engine looks for these patterns as a secondary signal.

DNS and WebRTC Leak Detection

Some VPN configurations leak the user’s real IP address through DNS requests or WebRTC protocols in the browser. SecurEcommerce can detect these leaks, confirming VPN usage even when the VPN’s IP itself is not yet in known databases.

Data Center IP Identification

Many VPN servers run on major cloud hosting platforms. Identifying traffic from data center IP ranges (rather than residential ISPs) is a strong indicator of VPN or proxy usage, even for newer VPN services that have not yet been cataloged.

Step 1: Access VPN Blocking Settings

1. Log into your Shopify admin panel
2. Open the SecurEcommerce app
3. Click Blocking in the left sidebar
4. Select VPN/Proxy Blocking

You will see the VPN blocking configuration page with options for VPN, proxy, and TOR traffic.

Step 2: Configure VPN Blocking

SecurEcommerce gives you granular control over how VPN traffic is handled. Choose the approach that fits your business needs.

Choose Your Blocking Action

You have three options for handling detected VPN traffic:

Block Completely

• The visitor sees a block page and cannot access your store at all
• Best for stores with strict geographic requirements or high fraud exposure
• Most aggressive option — will stop some legitimate customers

Show Warning Message

• The visitor sees a warning that VPN usage has been detected
• They are asked to disconnect their VPN to continue browsing
• Allows legitimate customers to proceed after turning off their VPN
• Good starting point if you are unsure about full blocking

Allow but Flag

• VPN traffic is allowed through but flagged in your analytics and logs
• Orders from VPN users are marked for manual review
• Least disruptive option — useful for monitoring before deciding on a policy

Enable VPN Detection

1. Toggle Enable VPN Detection to on
2. Select your preferred action from the three options above
3. If you chose “Block” or “Show Warning,” customize the message shown to visitors (see Step 3)
4. Click Save

Configure Proxy and TOR Separately

SecurEcommerce lets you handle different types of anonymized traffic differently:

• VPN Traffic — Commercial VPN services (NordVPN, ExpressVPN, etc.)
• Proxy Traffic — Web proxies and SOCKS proxies
• TOR Traffic — The Onion Router network

For each type, you can set a different action. A common configuration is:

Traffic Type	Recommended Action	Reasoning
VPN	Show Warning	Balances security with customer experience
Proxy	Block	Proxies are more commonly associated with abuse
TOR	Block	TOR traffic has the highest fraud correlation

Step 3: Customize Block and Warning Messages

When a visitor is blocked or warned, they see a message from your store. Making this message clear and professional helps legitimate customers understand what to do.

Write Your Block Message

1. In the VPN Blocking settings, find the Block Message section
2. Write a clear, helpful message. Example:

“For security purposes, access to our store is restricted when using a VPN or proxy service. Please disconnect your VPN and refresh the page to continue shopping. If you believe this is an error, contact us at support@yourstore.com.”

3. Optionally add a redirect URL to send blocked visitors to a specific page (such as a help page explaining your policy)
4. Click Save

Tips for Effective Messages

• Explain why the block exists (security/fraud prevention)
• Tell the visitor exactly what to do (disconnect VPN, refresh)
• Provide a way to contact support for false positives
• Keep the tone professional and non-accusatory — many VPN users are privacy-conscious, not malicious

Step 4: Decide Between Partial and Full Blocking

Not every page on your store needs the same level of VPN protection. SecurEcommerce supports partial blocking strategies that protect sensitive areas while keeping the rest of your store accessible.

Full Store Blocking

Blocks VPN traffic from accessing any page on your store. This is the simplest approach but the most restrictive. Use this when:

• You have strict geographic compliance requirements
• Fraud rates from VPN traffic are unacceptably high
• You are running a limited product drop (temporary full blocking)

Checkout-Only Blocking

Allows VPN users to browse your store and view products, but blocks them at checkout. This approach:

• Lets potential customers discover your products
• Prevents fraudulent purchases
• Reduces friction for casual browsers
• Is a good middle ground for most stores

To configure:

1. In VPN Blocking settings, find Blocking Scope
2. Select Checkout Only
3. VPN users can browse freely but are blocked when initiating checkout
4. Click Save

Page-Level Blocking

For the most granular control, you can apply VPN blocking only to specific pages or sections:

1. Select Custom Pages in the Blocking Scope section
2. Add the pages or URL patterns where VPN blocking should apply
3. Common choices: checkout, account creation, discount redemption pages
4. Click Save

Step 5: Monitor VPN Traffic and Adjust

After enabling VPN blocking, monitor the impact to ensure you have the right balance between security and customer access.

Review VPN Blocking Analytics

1. Go to Analytics > VPN Traffic Report
2. Review key metrics:
   • Total VPN visitors detected per day/week
   • Percentage of total traffic using VPNs
   • Breakdown by VPN vs. proxy vs. TOR
   • Actions taken (blocked, warned, flagged)
   • Geographic distribution of VPN users

Watch for False Positives

Some visitors may be incorrectly identified as VPN users. Watch for:

• Corporate network users — Some businesses route employee traffic through infrastructure that resembles VPNs
• Mobile carrier users — Certain mobile networks use IP pools that overlap with VPN databases
• Privacy-focused ISPs — A small number of ISPs offer VPN-like features built into their service

If you notice legitimate customers being blocked:

1. Check your blocking logs for the specific IP and block reason
2. Whitelist specific IPs or IP ranges for known partners and corporate customers
3. Consider switching from “Block” to “Show Warning” to give legitimate users an opportunity to proceed

Adjust Over Time

Your VPN blocking strategy should evolve:

• First week — Use “Allow but Flag” mode to understand how much of your traffic uses VPNs and what impact blocking would have
• Second week — Switch to “Show Warning” mode and monitor how many visitors disconnect their VPN to continue
• Ongoing — If warning mode works well, stay with it. If fraud persists, escalate to full blocking for checkout or the entire store

Frequently Asked Questions

Will blocking VPNs hurt my sales?

It depends on your audience. For most stores, VPN traffic represents a small percentage of total visitors, and an even smaller percentage of paying customers. The fraud reduction typically outweighs the lost sales. Start with warning mode to gauge the impact before committing to full blocking.

What about customers who use VPNs for privacy?

Many privacy-conscious customers use VPNs as a matter of routine. A clear warning message that explains why you restrict VPN access and asks them to temporarily disconnect gives these customers a path to purchase. Most will comply if the message is respectful and transparent.

Can sophisticated users bypass VPN detection?

Some VPN services offer “stealth” modes designed to evade detection. While no detection system is perfect, SecurEcommerce uses multiple detection methods and regularly updated databases to catch the vast majority of VPN traffic, including many stealth VPN configurations.

Should I block VPNs permanently or only during high-risk periods?

This depends on your fraud exposure. Stores with consistent fraud issues benefit from permanent VPN blocking at checkout. Stores that primarily face bot issues during product drops may prefer temporary full blocking during those events and lighter restrictions during normal operations.

Does VPN blocking affect SEO?

No. Search engine crawlers do not use VPNs, so blocking VPN traffic has no impact on how search engines index your store. Googlebot and other legitimate crawlers access your site through their own well-known IP ranges.
