AWS Certificate Manager vs GeoTrust

AWS Certificate Manager (ACM) provisions, manages and deploys public and private SSL/TLS certificates for AWS, hybrid and multicloud workloads. Certificates may cover one domain, multiple named domains, wildcard domains or combinations. Management is available through the AWS Management Console, AWS CLI and ACM APIs, with usage auditable in AWS CloudTrail logs. Amazon-issued certificates can renew automatically when DNS validation is used; otherwise ACM sends notices as expiration approaches. Public-certificate integrations include Elastic Load Balancing, Amazon CloudFront, Amazon API Gateway, AWS Elastic Beanstalk and AWS CloudFormation. AWS Key Management Service helps protect stored private keys. Customers can import third-party CA certificates and deploy them with Elastic Load Balancers, CloudFront and API Gateway; importing costs nothing. The default quota is 10 domain names per certificate, with requests up to 100. The integrated-services public-certificate plan is free and non-exportable. ACM is available on web and API platforms.

GeoTrust Horizon is a security platform for SSL certificates, certificate automation and monitoring, and vulnerability management. GeoTrust says it is intended for small and medium businesses and fast-moving builders. It offers DV, OV, and EV certificates issued from DigiCert trusted roots. AutoInstall SSL automates certificate installation, re-issuance, and renewal, supporting Apache, NGINX, IIS, LiteSpeed, cPanel, Kubernetes, Docker, and more. With automatic renewal enabled, certificates renew 28 days before expiry. SSL Monitor checks domains and subdomains daily for certificate expiry, trust issues, HTTPS vulnerabilities, and more than 110 SSL issues. Vulnerability Manager scans servers daily for more than 375,000 vulnerabilities and provides remediation instructions; scans can be internal with an installed agent or external without one. GeoTrust says the tool uses Qualys vulnerability detection technology. SSL Monitor costs $2 a month per standard domain, and Vulnerability Manager costs $12 a month per server. Technical chat support is available 24/7; email support uses tickets and phone support is available five days a week.
