The Challenge
Internal Detection Was Not Enough to Fight Fraud
Red Lemon Media had an internal manual check system for traffic validity, but the complexity and speed of modern fraudsters meant most ad fraud slipped through undetected — costing time, energy, and financial resources.
Incomplete & Unreliable Data
In-house solutions blocked a portion of fraud but never provided complete or reliable data. Without trustworthy analytics, proving invalid traffic to partners was nearly impossible.
Wasted Resources & Rising Costs
The team was still losing time, energy, and financial resources fighting ad fraud manually. In-house solutions were never as efficient as a specialised, automated detection system.
The Solution
Why Red Lemon Media Chose Opticks
After comparing leading solutions and benchmarking two providers, Red Lemon Media selected Opticks for its reliability, sophistication, and the specific level of detail needed to communicate fraud data to partners.
- 1
Most Reliable Detection
Opticks provided the most reliable detection and prevention systems, with highly sophisticated and personalised insights that went far beyond what internal tools could deliver.
- 2
Granular Detail for Partners
Specific levels of detail — source of threat, segmentation per partner, channel, and campaign — enabled Red Lemon Media to justify flagged leads and ease communication with affiliate partners.
- 3
Real-Time Automatic Protection
Opticks automatically protects traffic in real time. The marketing team consults the dashboard to identify high fraud rates and shares findings directly with partners.
- 4
GDPR Compliance & Support
An accessible and supportive team combined with a strong privacy guarantee (GDPR compliance) made Opticks the clear choice over competitors.
“Opticks was the most reliable and sophisticated option, and could provide the most specific level of detail that we needed to ease communication with our partners.”
