TL;DR: Choosing an SNA provider depends on consultative design support, production authentication success, edge-case handling, security posture, coverage, and commercial flexibility, according to IDlayr. For IAM and fraud teams replacing SMS OTP, the real question is whether the provider can support reliable identity assurance at scale, not whether it can demo a successful check.

By the numbers:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
Questions worth separating out
Q: How should security teams evaluate SNA as part of identity verification programmes?
A: Treat SNA as an assurance control with operational dependencies, not as a simple replacement for SMS OTP.
Q: When does SNA create less value than teams expect?
A: SNA creates less value when teams assume the network check alone solves fraud.
Q: What do identity teams get wrong about mobile-based authentication factors?
A: Teams often mistake a successful demo for a reliable production control.
Practitioner guidance
- Validate real-world authentication success rates Test live SNA performance across your own device mix, carrier mix, and target markets before approving production use.
- Assess the provider as part of the assurance boundary Review certifications, retention, residency, minimisation, and logging as procurement gates, not as paperwork after go-live.
- Probe edge cases before replacing SMS OTP Ask for demonstrations on Wi-Fi-connected devices, devices with active VPNs, and multi-SIM phones, then verify what happens when cellular access is unavailable.

IDlayr's full article covers the operational detail this post intentionally leaves for the source:
- The question set for evaluating consultative support before integration, including deployment design, business case framing, and pre-launch review.
- The practical differences between direct and aggregated carrier connections, including how they affect latency and production success rates.
- The detailed edge-case questions for Wi-Fi, VPN, dual-SIM, MVNO coverage, and TS.43 browser flows.
- The commercial and support considerations that matter when a pilot moves into scale, including pricing tiers, fallback behaviour, and optimisation analytics.

SNA provider selection: what IAM and fraud teams should evaluate?

SNA provider choice is an identity governance decision, not a messaging procurement exercise. The article's strongest point is that replacing SMS OTP changes the control boundary, so vendor selection must examine assurance quality, integration support, and post-launch ownership. In practice, that means the buyer is selecting a partner in the identity decision chain, not a transport layer. Practitioners should evaluate SNA through the lens of identity assurance governance, not telecom convenience.
A question worth separating out:
Q: Who should own the risk when SNA becomes part of customer authentication?
A: Accountability should sit with the identity, fraud, and platform owners together, because the factor spans assurance, user experience, and operational resilience. The provider is a dependency, not the owner of your risk. Governance should cover approval, monitoring, fallback paths, and post-incident review.
