In 2024 and 2025, Dainius and his team earned four major industry awards for Threat Protection Pro™. AV-Comparatives awarded them a certificate for fake-shop detection in 2024. This certification confirmed that the solution effectively protects users from fraudulent online stores.

The team also received three prestigious medals. First, AV-Comparatives approved Threat Protection Pro™ as an anti-phishing solution, making NordVPN the first and only VPN to receive this recognition. AV-Test also honored Threat Protection Pro™ as the best antimalware solution among VPNs, and WCL awarded it the same distinction. These achievements are a culmination of year-long testing processes conducted by independent cybersecurity organizations, with certificates and medals awarded at the end of each testing period.
