Entrust Certificate Manager

Entrust Certificate Manager is part of Entrust Certificate Services, a web-based certificate lifecycle management platform that helps you manage all of your digital certificates, from Entrust and other Certification Authorities (CAs). Entrust Certificate Manager allows organizations with large numbers of private and public trust certificates to monitor and track their in-use certificates. New certificates can be requested, issued and downloaded for immediate deployment all without leaving the ServiceNow environment. Role-based access control is available to identify the persons in the organization responsible for certificate administration. Other users can be assigned permissions to request certificates subject to an additional approval workflow where a certificate administrator must approve their request prior to a certificate being issued. Integration with both Entrust Certificate Services and the Entrust CA-Gateway allows both public trust and private trust certificates to be issued and managed in ServiceNow. Integration with the ServiceNow CMDB module ensures that all digital certificate that are created in your organization will automatically be added to CMDB and tracked as CIs alongside all of your other IT assets. This application is domain-separation aware. Users and administrators assigned to domains are only able to see requests and certificates for the organization(s) assigned to their domain to support MSP workflows. Individual certificate users can view their issued certificates and "self-service" request replacement certificates prior to the certificates expiring. Certificate administators also have the ability to view all issued certificates and issue replacement certificates on behalf of their users. Key Features - Request, renew and download SSL/TLS certificates without leaving ServiceNow - Presents an approval workflow in ServiceNow for certificates requested by users other than certificate administrators - Synchronizes the list of certificates and certificate metadata with your Entrust Certificate - Services account or your Entrust CA-Gateway - Integration with ServiceNow CMDB and ServiceNow Certificate Management application - Support for Domain Separated instances to support MSP workflows

SSLBoard

SSLBoard delivers comprehensive TLS security audits and compliance-ready reports for any domain, on demand. Scan once, get a complete picture of your organization's TLS posture across every host, certificate, cipher suite, and protocol, all mapped against the compliance frameworks that matter to your business. SSLBoard goes beyond certificate discovery. It evaluates your entire TLS estate against 17 regulatory and industry frameworks including PCI-DSS v4.0.1, NIS2, ISO 27001, SOC 2, DORA, HIPAA, FedRAMP, NIST SP 800-52, and others. Each finding is scored, prioritized by compliance impact, and tied to specific regulatory requirements so security teams and auditors know exactly what to fix and why it matters. Every scan checks certificate health, protocol versions, cipher suite strength, forward secrecy, HSTS and web hardening, DNSSEC configuration, and post-quantum cryptography (PQC) readiness. SSLBoard detects weak or unsafe cipher suites, missing CAA records, deprecated protocols, and certificates approaching expiration, then tells you which compliance obligations each finding affects. Reports are structured for both human readers and machine consumption. Markdown summaries, CSV exports, and structured data formats make it easy to feed results into existing workflows, AI assistants, or compliance documentation pipelines. No account required, no integration overhead, no agents to install. Point SSLBoard at a domain and get actionable audit evidence in minutes. SSLBoard serves IT administrators, security teams, compliance officers, and auditors who need defensible TLS assessment data without the complexity and cost of annual enterprise contracts. Pay per report, scan any domain regardless of certificate authority or hosting provider, and get results that are ready for your next audit review.
