An Adaptive Approach to Fraud & Account Security
We believe the only way to combat the online fraud epidemic long term is to actively undermine the profitability of attacks. The Arkose Labs platform is designed to break down the business model of fraud by sabotaging bots and sapping attackers’ resources until attacks become financially non-viable.

Our AI-powered platform equips fraud & security teams with the detection, insight, and enforcement power they need today to not only mitigate, but deter increasingly unpredictable attackers long-term.
Fraud Deterrence Platform
Root out persistent attacks with real-time risk classifications and dynamic attack response, powered by multi-faceted machine learning and 24/7 SOC support.
Unlike other fraud prevention solutions, our “clear box” approach delivers actionable insights. It provides clear explanations for risk classifications and flexibility to segment traffic for remediation – through our proprietary enforcement challenge technology or pressure of your choice.
The combination of transparency and dynamic attack response allows fraud and security teams to confidently navigate suspicious traffic when trust signals are unclear.

Key Features of the Arkose Labs Platform

Make smarter decisions with actionable insight into fraudulent intent. Supervised and unsupervised machine learning constantly optimizes the accuracy of the platform’s risk scores – making it the fastest learning fraud decision platform on the market.


Real-time signals pass through a rapidly-evolving rules engine to analyze signals against known nefarious behaviors.

Response Orchestration

Traffic is expertly segmented by risk to determine the most effective response for that attack signature.

Embedded Machine Learning

Self-optimizing system improves our decision models with each assessment.

Historical Attack Pattern Calibration

Correlates attack patterns across use cases and industries to understand how they are orchestrated.

Anomaly Detection

Analyze the network traffic patterns in real-time to determine behavior patterns across cohorts.


Complete visibility into risk assessment and real-time data sharing to enhance your risk models.

How it Works

Arkose Labs determines true user intent by analyzing traffic for behavioral telltales of fraud and validating suspicions using interactive challenges.
Real-time detection classifies traffic and informs the business if secondary screening is necessary. Suspicious traffic is triaged and flagged for proprietary challenges to further validate traffic as large-scale bots or human-based attacks. An immediate feedback loop feeds the Arkose platform to enhance models with truth data and optimize decisioning for future attacks. Meanwhile, good users convert quickly through invisible screening to reduce friction and increase throughput.

Arkose Decision Engine

An AI-powered risk engine delivers adaptive decisioning to classify traffic and orchestrate the best attack response.


Invisible screening collects real-time intelligence and behavioral signals to spot tell-tale signs of fraud on the most targeted user interaction points on websites and apps.


Remediate attacks in real time with an innovative challenge-response system that tests high-risk traffic to distinguish between authentic users, malicious humans, and bots.

Arkose Global Network

Keep ahead of evolving threats using network intelligence that correlates attack patterns across industries and use cases, to detect anomalous behavior and emerging attacks.

Shifting the Attack Surface

Arkose Labs provides an intermediary platform to verify requests, acting as a buffer between fraudsters and the websites and apps they are so practiced in attacking.

Our platform integrates into consumer facing touch-points to protect logins, account creation and other user actions. When a user completes an action on a webpage or app protected by Arkose Labs, the platform analyzes this for suspicious telltales.

Rather than blocking traffic outright, high-risk activity is tested through interactive technology, relieving the burden on in-house teams. Challenge results feed back into the risk engine as truth data to clarify gray signals and evolve with attack patterns.

The Fastest Path to a Zero Tolerance on Fraud

Seamless Integration

No reverse proxies, third-party infrastructure, daily rule-setting or single point of failure.

User Centric

The highest good user throughput of any form of step-up, tested against MFA and traditional CAPTCHAs.

Rapid Results

New customers see results within days and are fully deployed within weeks

Arkose Detect

Real-time risk classification to uncover the subtlest signs of fraudulent intent
Risk classification for a world where digital identities have been corrupted at scale

The behavior of a fraudster becomes clearer through the lens of what motivates them – profit. That’s why Arkose Detect focuses on uncovering tell-tale signs of nefarious intent and actions.

Arkose Detect carries out deep analysis of behavior and device heuristics to flag suspicious activity. Our insight-rich, open platform gives you 50+ attributes to augment your decision-making and is easily implemented with internal attack response strategies. Actionable visibility into user intent means companies eliminate gray area traffic that lead to false positives and negatives.

Arkose Detect Key Features

Arkose Enforce​

A challenge-response mechanism which delivers targeted friction to high-risk traffic to remediate attacks in real time.

Smarter step-up that increases good customer throughput.

Traditional step-up authentication solutions are failing to stop fraud attacks at scale, without killing businesses’ conversion rates. That’s why Arkose Labs takes a different approach to any other fraud provider on the market.

Through seamless integration with Arkose Detect, it preserves challenges for risky traffic only. Arkose Enforce generates 3D images in real-time which are tailored to the risk profile and cannot be bypassed by fraudsters at scale.

Create Hurdles for Fraudsters,
Not Customers

Most solutions place too much of an emphasis on blocking suspicious traffic, which leads to good customer friction or letting too many bad guys through. Arkose Labs acts as a major obstacle for fraudsters, but an open door for your customers. 

We achieve this by taking a unique approach of not blocking any traffic, but rather triaging suspicious traffic to the Arkose Enforce challenge.

The challenges cannot be solved by bots and they become increasingly difficult for human fraudsters to solve. This saps their time and resources until they can no longer profit from attacking you.

Good users with clear trust signals bypass challenges. In the event they see one, Arkose Enforce challenges deliver the highest solve rate, accelerating completion rates without manual intervention.

Eliminate Automated Attacks

Arkose Labs is the only fraud vendor to offer a commercial SLA guarantee against bot attacks of any sophistication level as standard. Interactive technology tests the responses of a device behind the scenes, and presents authentication puzzles to suspected bots that cause them to fail. 

Challenges are created using 3D visuals, with countless possible permutations. They are designed against the grain of machine vision software, so that they cannot be recognized and classified by machines. Context and logic are used, which is simple for humans but hard for bots to make sense of. A wide bench of challenges allows businesses to rotate puzzles when an automated attack is suspected. 

All this means that it is impossible for fraudsters to launch a profitable automated attack on businesses that are protected by Arkose Labs.

Arkose Enforce - Challenge Types

With Arkose Enforce, we make it impossible for fraudsters to launch a profitable automated attack against you. By continually undermining the profitability of attacks, we ensure your websites & apps become less viable attack surfaces.
