Why vpn and proxy abuse costs advertisers so much
The damage goes beyond wasted clicks. VPN and proxy abuse corrupts your bidding data, distorts your audiences, and erodes the performance of every campaign it touches.
VPN and proxy abuse occurs when fraudulent traffic is routed through virtual private networks or anonymous proxy servers to disguise its true origin. Advertisers who geo-target their campaigns are particularly exposed, as fraudsters use VPNs to appear as if they are clicking from within the target geography while actually operating from anywhere in the world.
Beyond geo-targeting fraud, VPN and proxy abuse is used to circumvent IP-based frequency caps, allowing the same fraudulent operator to click your ads repeatedly without triggering volume-based detection. It also enables coordinated fraud operations to hide the centralised source of their traffic, making it appear to come from thousands of different legitimate users.

How Tapper detects and blocks vpn and proxy abuse
Real-time detection and blocking across all your ad platforms, with no engineering required.
01
Identify VPN and proxy endpoints
Tapper maintains a continuously updated database of known VPN providers, proxy services, and anonymising networks, cross-referenced against every click your campaigns receive.
02
Assess intent, not just the IP
Rather than blanket-blocking all VPN traffic, Tapper scores each session holistically — a legitimate user on a corporate VPN behaves very differently from a fraud operation hiding behind one.
03
Block confirmed fraud, protect legitimate users
Only traffic confirmed as fraudulent is blocked, with a 0.1% false positive rate ensuring genuine users are never excluded from your campaigns.
Choose your platform
Each platform has its own variation of vpn and proxy abuse. Tapper handles all of them.

“During our Tapper trial for INFINITI, we uncovered low-quality traffic that wasn't visible inside the platforms. Removing it delivered a 14% uplift in conversions and an 11.4% reduction in CPA - a meaningful efficiency gain for INFINITI's 2026 growth plans.”

“With Tapper's protection we were able to identify and block invalid clicks in real time. The impact was immediate as our cost per acquisition dropped by 30% and ROAS improved significantly. More importantly, Tapper gives us the confidence that our campaigns are reaching genuine customers, which makes it truly invaluable.”
Dimitris Bakas
Senior Performance Marketing, Public Group
“We started using Tapper to get better visibility on where our clicks were coming from, and ended up cutting wasted spend by over 12%. The performance uplift was clear, and for the first time, we could trust the numbers we were seeing. It's a total game-changer for campaign integrity.”
Stuart Parkin
Director of Operations, Regit
“Tapper's blocking technology purifies our paid media traffic which roughly equates to a 36x return against its subscription costs. It's certainly one of the easiest-to-implement tools in our entire marketing stack.”
Reno Mindemann
Head of Growth, Kama Capital
“We've been using Tapper for over a year now, and it has become a core part of how we run paid media. Invalid traffic was always something we knew existed but couldn't really act on. Tapper changed that. We're now saving up to $50K per year, and on PureSquare specifically, we saw around a 20% decrease in CPA. Based on these results, we decided to roll it out across other ventures under Disrupt as well.”
