Designed with developers in mind, FusionAuth integrates seamlessly with any language, framework, or architecture. Every capability is API-first and built for extensibility, so you can tailor authentication workflows without getting locked into rigid, inflexible systems.
FusionAuth supports all the key use cases — user registration, multi-factor authentication (MFA), passwordless login, role-based access control, and more — while helping you stay compliant with GDPR, HIPAA, PCI, and other regulatory standards.

ARGOS Identity makes two products: ARGOS ID Check for identity verification (KYC/eKYC) and ARGOS Omni, a Review Ops Agent that reviews documents and data case by case.
ARGOS ID Check combines ID document recognition and authenticity checks (OCR, MRZ and driver's license PDF417 barcode checks, ID liveness against photocopies and screen replays), selfie-to-ID face comparison, passive and active liveness that detects photos and deepfakes, and AML screening against sanctions and PEP lists with ongoing monitoring. It covers 4,000+ ID document types, including passports, national IDs, driver's licenses and residence permits, from 200+ countries. Teams ship it as a hosted Liveform (one URL, 26 languages, web and app WebViews) or build their own UI on the Verify engine APIs, and receive results by webhook, return URL or REST API. ARGOS Score thresholds and custom policy rules decide each case, and pending cases go to your team or ARGOS Expert Reviewer. ID Check is ISO/IEC 27001 certified.
ARGOS Omni is a Review Ops Agent for document and data review. Teams write their review criteria in plain language; Omni turns them into a playbook and, for each case, checks the submitted documents, extracts data into the output schema you define, cross-checks documents against each other and runs external lookups such as AML screening of people and companies. It returns verified, rejected or pending_review, and records the reason and source step behind every value. Use cases include KYB document review for business onboarding, vendor onboarding, corporate telecom subscription review, insurance claim review and AML review.
Pricing is usage-based and quoted by sales.

SentryFusion
SentryFusion allows a more secure, multi-factor analysis for access control to critical resources and areas. SentryFusion includes a cluster-based architecture that provides effective scalability, robustness, and future-proofing, along with the option of hosting on-premise or in a data center. Identify a user's voice and face during a video call so that they may later be recognized during a voice conversation, video call, or image. With identity theft on the rise, MFA is increasingly used to prevent unauthorized access to customer data or financial resources. This opens up the possibility of better-than-real-time operation, even in large-scale authentication scenarios. SentryFusion provides near-instantaneous results, streamlining the authentication process and removing the unnecessary hassle for end users.
