Non-human and machine identities now greatly outnumber human identities and effectively managing them is essential to implementing an identity-first security approach to support your zero trust initiatives. While PKI is foundational to providing trusted non-human and machine identities, managing certificates is a challenge for many organizations. Additionally, major disruptions in the PKI landscape, such as CA distrust issues, shorter validity TLS certificates and Post-Quantum Cryptography (PQC) readiness, are compounding the issue. Crypto-Agility is the answer to solving these challenges to ensure a strong enterprise security posture.
