# Best Risk-Based Authentication Software - Page 4

  *By [Brandon Summers-Miller](https://research.g2.com/insights/author/brandon-summers-miller)*

   Risk-based authentication (RBA) software analyzes user variables, including IP addresses, devices, behaviors, and locations, to dynamically assess risk and apply customized authentication requirements, automatically signing in low-risk users while prompting suspicious users for additional verification such as SMS codes or biometric confirmation.

### Core Capabilities of Risk-Based Authentication Software

To qualify for inclusion in the Risk-Based Authentication category, a product must:

- Assess a user's unique network, device, and behavior to determine risk
- Prompt authentication measures after assessment
- Utilize authentication methods such as SMS, security questioning, or email confirmation
- Periodically store and update suspicious networks, devices, and behaviors

### Common Use Cases for Risk-Based Authentication Software

Security and IT teams use RBA software to strengthen access governance without degrading the experience for legitimate users. Common use cases include:

- Automatically authenticating trusted users from known devices and locations without friction
- Requiring step-up authentication for anomalous login attempts based on IP reputation or geolocation
- Reducing account takeover risk by continuously updating risk profiles based on behavioral patterns

### How Risk-Based Authentication Software Differs from Other Tools

RBA products often contain [multi-factor authentication](https://www.g2.com/categories/multi-factor-authentication-mfa) features but apply them selectively based on the administrator's risk configuration rather than universally. RBA tools may also work in sync with [customer identity and access management (CIAM)](https://www.g2.com/categories/customer-identity-and-access-management-ciam) products, though they typically provide only the authentication component rather than the full suite of application access and governance capabilities.

### Insights from G2 on Risk-Based Authentication Software

Based on category trends on G2, adaptive authentication accuracy and low friction for trusted users stand out as standout capabilities. These platforms deliver reductions in account compromise incidents and improved authentication user experience as primary outcomes of adoption.

### 17. [Secfense User Access Security Broker](https://www.g2.com/products/secfense-user-access-security-broker/reviews)
  Secfense is a proxy-based authentication platform that enables enterprises to deploy phishing-resistant multi-factor authentication (MFA), passkeys, Windows Hello, and microauthorizations across every application - without code changes or system replacements. Acting as a universal authentication layer: Secfense sits between users and applications, upgrading the security of all systems - even legacy or custom-built ones - to modern standards such as FIDO2, passkeys, or Windows Hello. Unlike traditional IAM solutions that require rewrites or proprietary integrations, Secfense works as a vendor-neutral overlay that brings passwordless, phishing-resistant login to every system. Most enterprises still rely on passwords or have partial MFA coverage. Legacy and on-premises applications and SSO often can't support modern authentication methods, and rewriting them is expensive and risky. As a result, more than 80% of breaches continue to originate from compromised credentials. Meanwhile, emerging regulations such as DORA and NIS2 mandate phishing-resistant authentication, something existing IAM tools alone cannot easily achieve across diverse applications. Secfense closes this gap. Operating as a reverse proxy, it intercepts login requests and dynamically injects FIDO2-based authentication - including passkey prompts, biometric checks, or hardware key authentication - before passing validated sessions to the protected applications. The entire process is transparent to both users and applications: No code changes, no app modifications, and no disruption to operations. Secfense seamlessly integrates with existing identity providers, including Entra ID, Okta, Ping, and others, via SAML and OIDC protocols. Rather than replacing these systems, Secfense extends them with phishing-resistant capabilities while allowing organizations to fully control their identity architecture. Trusted by banks, insurers, and other regulated industries, Secfense delivers the fastest, most practical path to secure, compliant, and passwordless authentication across the enterprise - reducing deployment times from months to weeks and cutting IAM modernization costs by up to 87%.

#### What is risk-based authentication?

Risk-based authentication is a dynamic security approach that evaluates contextual signals, device, location, IP, and behavior on each login attempt and applies authentication friction proportional to the calculated risk, allowing low-risk users through seamlessly while stepping up verification for suspicious attempts.

#### What is the best RBA platform for reducing fraud?

Platforms built for fraud reduction combine behavioral analytics, real-time risk scoring, and machine learning to catch account takeover and fraudulent transactions without disrupting legitimate users. Here are the best platforms for reducing fraud:

#### Which vendor provides AI-powered adaptive authentication?

AI-powered adaptive authentication platforms use machine learning and behavioral signals to continuously refine authentication decisions beyond static rules. These are the vendors that provide the best AI-powered adaptauthentication:  

- [Cisco Duo](https://www.g2.com/products/cisco-duo/reviews): Provides risk-based MFA that responds to anomalous login signals, rated for reliable device trust controls and integration with enterprise SSO and VPN infrastructure used by distributed engineering teams.

#### Is risk-based authentication the same as multi-factor authentication?

No. [Multi-factor authentication (MFA)](https://www.g2.com/glossary/multi-factor-authentication-definition) applies the same verification steps on every login regardless of risk, while risk-based authentication **(**RBA) dynamically decides whether additional authentication is needed at all, invoking step-up challenges only when signals indicate a suspicious attempt.
