M&T Bank, a Fortune 500 American bank, was focused on transforming its digital footprint and embracing agility to meet constantly evolving customer needs. However, with digital transformation came the need for digital trust and security. The bank relied on Public Key Infrastructure (PKI) and digital certificates to securely connect devices and applications across its digital footprint. Over the years, technology and cryptography evolved significantly, creating new challenges. M&T Bank initially partnered with Keyfactor in 2010 to migrate from SHA-1 to SHA-2 and re-build their entire PKI. However, as the number of devices and workloads expanded rapidly, so did the number of certificates required across their environment. The increasing volume and speed at which certificates were issued made it difficult to keep track of them.
