Device Profile Smart – Device Fingerprinting & SCA
Secure your online services with Strong Customer Authentication (SCA) using a persistent digital device fingerprint.
What is Device Profile Smart and how does it support SCA?
Why is Device Profile Smart stable for device identification?
Device Profile Smart uses multiple fingerprint streams instead of one static identifier. This makes device recognition more stable during typical environment changes (e.g., browser or system updates).
Device Profile Smart uses unique technical characteristics of the device and browser to build fingerprint streams.
Does the technology still recognize a device after an update?
Yes. Device Profile Smart relies on multiple fingerprint streams, not a single identifier.
When does Device Profile Smart indicate that additional verification is needed?
When changes to the fingerprint set exceed a defined threshold compared to the baseline.
How does Device Profile Smart work?
How is Device Profile Smart implemented?
01
Device Profile Smart is enabled by adding a single line of JavaScript code to the protected page.
02
The solution operates in the Security-as-a-Service model. The entire infrastructure and updates are managed by PREBYTES.
03
The script loads asynchronously (non-blocking), helping keep page performance and the User Experience (UX) smooth.
Device Profile Smart for organizations with high security requirements
Does Device Profile Smart work across browsers and devices?
Device Profile Smart works across desktop and mobile environments and supports both modern and older browser and device versions. We prioritize broad compatibility to deliver stable, reliable performance across different OS and browser combinations.
Cookie-less and resilient to ad blockers and privacy tools
Device Profile Smart is cookie-less (it does not use cookies), and is designed to be resilient to common ad blockers and privacy tools. It maintains stable device identification and a security assessment.

Supports compliance with PSD2, SCA & NIS2
Device Profile Smart supports PSD2 SCA by providing a device fingerprinting signal that can be used as a device-based possession input in authentication and step-up decisions. It can also support security practices aligned with NIS2 risk-management expectations by helping reduce account takeover and fraud risk.
How does Device Profile Smart differ from typical anti-fraud tools?
The table below compares Device Profile Smart with typical anti-fraud solutions across the most important technical and business areas.
COMPETITOR SOLUTIONS
Multiple fingerprint streams keep device identification stable even when the environment changes
A single static fingerprint changes after minor modifications
Privacy by design; supports GDPR, PSD2/3 and NIS2 compliance
Profiling and biometrics increase regulatory requirements and require user consent
Works from day one – no model training phase required
Biometric models require a training period (weeks/months)
Runs in the background and reduces unnecessary step-up verification
More frequent extra checks reduce UX and add friction
Works across modern and older browsers/devices; optimized for mixed OS/browser versions
May have limited support for older browsers/devices or require frequent updates for compatibility
Faster ROI and reduced fraud losses
Higher costs: more SMS step-ups
Proprietary ML models trained on large-scale device data
Off-the-shelf libraries (e.g., from GitHub) that are easier for fraudsters to bypass
The solution is not treated by ad blockers as a tracker
Vulnerable: often blocked as third-party trackers
Dedicated (EU/EEA, UK or US), hosting; full data residency; no public cloud
Shared cloud: multi-region hosting, which may place data outside the customer’s jurisdiction

Key benefits of implementing Device Profile Smart

Frequently asked questions about Device Profile Smart (FAQ)
Which industries is Device Profile Smart designed for?
Device Profile Smart is engineered for entities requiring the highest cybersecurity standards. Currently, it is utilized by major commercial banks and financial institutions. The solution also effectively protects e-commerce platforms, gaming services, and large-scale organizations where securing user accounts is a top priority.
Can the effectiveness of Device Profile Smart be tested before deployment?
Yes. You can verify Device Profile Smart’s effectiveness through a Proof of Concept (PoC). We recommend a minimum period of 2 months in a production environment. This provides data-driven validation of authentication accuracy and threat detection, giving you certainty of the solution's value before full implementation.
Does Device Profile Smart use cookies for tracking?
No. Device Profile Smart does not use cookies or store them in the user’s browser.
Does implementing Device Profile Smart affect page loading speed?
No. The Device Profile Smart script loads asynchronously (non-blocking), helping keep website rendering and User Experience (UX) smooth.
Which KPIs does implementing Device Profile Smart improve?
Device Profile Smart can improve security KPIs by helping reduce account takeover (ATO) and fraud risk. It can also improve cost and efficiency KPIs by lowering step-up costs and shortening time-to-value with protection available from day one.
Why are fingerprint streams more effective than a single static identifier?
Traditional, single fingerprints can be unstable – browser updates, hardware changes, or added plugins may change the identifier and increase false positives. Device Profile Smart addresses this by using multiple independent fingerprint streams to improve stability across typical environment changes, helping reduce unnecessary friction for legitimate users.
Does Device Profile Smart require a learning period before it starts protecting the online platform?
No. Device Profile Smart can provide protection from the moment of deployment. Unlike solutions that require weeks of training, Device Profile Smart works immediately and returns results when triggered at defined journey points.
At what point during a session does Device Profile Smart perform device fingerprint analysis?
Device Profile Smart runs analysis at user journey checkpoints defined by the organization. In addition to login, the analysis can also be triggered at moments that require a higher level of security such as transaction authorization or sensitive data changes.
How does the collaboration with PREBYTES continue after the Device Profile Smart implementation?
Our partnership is ongoing. Rather than a one-time implementation, we provide continuous support. Device Profile Smart is continuously improved in response to global trends, and regular sessions with our experts give you space to share current needs and review analytics results together.
