AWS Certificate Manager is a free certificate lifecycle management tool. DigiCert TLS/SSL Certificates is a commercial certificate lifecycle management tool by DigiCert. Compare features, ratings, integrations, and community reviews side by side to find the best certificate lifecycle management fit for your security stack.
Based 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.
Startups and SMBs that need encryption deployed without certificate management overhead should pick DigiCert TLS/SSL Certificates for the automated lifecycle handling and unlimited issuance across single, wildcard, and multi-domain options. The CertCentral portal handles renewals, replacements, and inventory at scale, eliminating the manual tracking that kills small teams. Skip this if your primary concern is vulnerability scanning or brand protection; those features live only in the higher-tier Secure Site Pro offering and shouldn't be your deciding factor.
