Certificate management is the process of issuing, renewing, revoking, and tracking digital certificates (X.509/TLS) across an organization's infrastructure. It includes managing certificate authorities, automating renewals to prevent expiration outages, and maintaining an inventory of all certificates in use. Tools like Let's Encrypt, AWS Certificate Manager, and Venafi automate certificate lifecycle tasks.
Why Certificate Management Matters for Your Cybersecurity Career
Expired certificates cause outages. Mismanaged certificates create security gaps. Organizations with thousands of certificates need people who can track and automate the entire lifecycle. Security engineers who can manage certificate infrastructure and implement certificate automation prevent both security incidents and availability problems.
