CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Teams running most or all of their infrastructure on AWS should use AWS Certificate Manager because it eliminates certificate procurement friction and automates renewal for resources already locked into the ecosystem, with zero per-certificate cost. ACM integrates natively with CloudFront, ALB, NLB, and API Gateway, meaning certificates provision in minutes and renew automatically without manual intervention or tooling. Skip this if your architecture spans multiple cloud providers or on-premises infrastructure heavily; you'll end up managing certificates across three different systems anyway, and a third-party platform will serve you better than jumping between vendor consoles.
SMB and mid-market organizations that need qualified electronic signatures under eIDAS 2.0 regulation should pick CRYPTAS PrimeSign; it's operated by a qualified trust service provider in Austria, meaning your certificates carry legal weight in EU proceedings without requiring a separate TSP relationship. The tool handles the full certificate lifecycle from root CA operation through remote signature device management, and its NIS2 compliance covers supply chain risk controls that most signature platforms skip. Skip this if you're outside the EU regulatory orbit or need signatures to also anchor broader PKI and device identity management; PrimeSign is deliberately deep in one channel rather than broad across identity platforms.
