As answered by people managing CodeSignal and SHIELD.
SHIELD's answer:
Most fraud solutions are web-first and rely heavily on personal data and static identifiers that are easily bypassed. They are also often focused on addressing fraud at specific checkpoints. SHIELD is device-first. Fraudsters can spoof data, accounts, and even identities, but they always need a device to act. This is why we stop fraud at the root.
SHIELD's answer:
Our plug-and-play SDKs and lightweight JavaScript snippets can be integrated in a matter of hours — not weeks or months. There’s no training period required, enabling your team to start detecting fraud immediately. Most customers see tangible results on day one, with zero disruption to existing workflows.
SHIELD's answer:
SHIELD works with digital businesses across every region and industry where trust and safety are mission-critical. Our customers include global unicorns and fast-scaling platforms in mobility, fintech, e-commerce, igaming, digital identity, and more. If your platform faces fraud, or trust & safety challenges, SHIELD can help you eliminate malicious users and scale growth with confidence.
SHIELD's answer:
SHIELD deliver real-time device intelligence globally, with offices in San Francisco, Singapore, Jakarta, Dubai, London, São Paulo, and more. We are a global team, which helps us stay close to the latest fraud trends, and our clients.
