Castle ingests the data points that most organizations either ignore or aren't aware of (e.g., mobile device operating system, internet service provider, IP location) to identify bad actors, account takeovers, or levels of risk that organizations aren't comfortable with. The solution is easily deployed and easy to maintain. Lastly, the Castle team is fantastic to work with and typically responds to questions within an hour, which is incredible. **What do you dislike about Castle?** No overall dislikes; just excited for new and enhanced capabilities. **What problems is Castle solving and how is that benefiting you?** Castle identifies risk within the electronic fingerprint of users that log into an organization's mobile application or online platform. Castle is very successful at identifying bad actors based on a review of a user's device details, such as IP location, mobile device type, internet service provider, etc. Castle can also assist an org to restrict or allow specific geographies based on their product/service offering or other regulatory requirements, and can also assist to prevent account takeovers, bots, and hacking attempts. ## Castle Discussions - [What is Castle used for?](https://www.g2.com/discussions/what-is-castle-used-for) - [View Castle pricing details and edition comparison](https://www.g2.com/products/castle/reviews?section=pricing&secure%5Bexpires_at%5D=2026-09-15+10%3A00%3A02+-0500&secure%5Bsession_id%5D=1ff84215-3e7c-4372-bffd-21d143197287&secure%5Btoken%5D=b743f4ad16bbb689bf584fa7b6aa3694a1acaa5586d9371777b8b53a2632af5b&format=llm_user) ## Castle Features **Additional Functionality** - Fraud Detection - PCI Compliance - Application Management - Audit Management - Single Sign On - Secure Data Storage - SSL Security - Privileged Account Management - Reporting & Statistics - Two-Factor Authentication - Member Accounts - HIPAA Compliant - AI Copilot - Self-Service Access Request - User Provisioning - Audit Trail - Third-Party Integrations - Real-Time Notifications - Active Directory Integration - Authentication - Compliance Management - Workflow Management - Access Controls/Permissions - Access Management - Secure Login - Customizable Branding - Real-Time Monitoring - Security Auditing - Policy Management - Data Synchronization - Collaboration Tools - API - Unified Directory - Multi-Factor Authentication - Biometrics - Activity Dashboard - Generative AI - Credential Management - Event Logs - Real-Time Analytics - Password Management - Access Certification - Self Service Portal - Mobile Access **Detection** - Payment Verification - Bot Mitigation - Real-Time Monitoring - Alerts **Administration** - Bi-Directional Identity Synchronization - Policy Management - Cloud Directory - Application Integrations - Password Synchronization - Password Management - Credential Management - Password Policies **Bot Detection & Classification - Bot Detection and Mitigation** - Bot Traffic Analytics - Good Bot Identification - Malicious Bot Detection **Intelligence** - Transaction Scoring - Risk Assessment - Intelligence Reporting - ID Analytics **Analysis ** - ID Analytics - Intelligence Reporting - Incident Reports - Reporting/Analytics **Protection & Mitigation - Bot Detection and Mitigation** - Automated Bot Mitigation - API Abuse Protection - Account Takeover Protection **Detection** - Fraud Detection - Alerts - Real-Time Monitoring **Administration** - Fraud Markers - Transaction Scoring - Blacklisting **AI-Powered Detection & Intelligence - Bot Detection and Mitigation** - AI-Powered Bot Detection - AI Agent & LLM Traffic Management - Adaptive AI Threat Response **Additional Functionality** - Web Traffic Monitoring - Anomaly/Malware Detection - Fraud Detection - Event Logs - Bot Mitigation - Vulnerability Scanning - Real-time Alerts - Threat Intelligence - Bot Detection - Dashboard - AI/Machine Learning - Generative AI - AI Copilot - Behavioral Analytics **Response** - Device Tracking - Fraud Markers - Blacklisting - Bot Mitigation **Agentic AI - Fraud Detection** - Cross-system Integration - Adaptive Learning - Decision Making **Additional Functionality** - Onboarding - Risk Management - Digital Signature - Workflow Management - Data Capture and Transfer - Consent Management - Customer Data Management - AI Copilot - Mobile Access - For Financial Institutions - Audit Trail - Video Conferencing - Behavior Tracking - API - Compliance Management - Blockchain Support - SDKs - Search/Filter - Geolocation - Generative AI - Multi-Language - Scheduling - Authentication - Case Management - Approval Process Control - Alerts/Notifications - Access Controls/Permissions - Lifecycle Management - Secure Data Storage - Address Validation - Biometrics - Document Management - Forms Management ## Top Castle Alternatives - [SEON](https://www.g2.com/products/seon/reviews) - 4.6/5.0 (384 reviews) - [Cisco Duo](https://www.g2.com/products/cisco-duo/reviews) - 4.5/5.0 (501 reviews) - [Sift](https://www.g2.com/products/sift-s-ai-powered-fraud-decisioning-platform-sift/reviews) - 4.6/5.0 (601 reviews)
