I work with Certera, an SSL/TLS and PKI provider offering certificates from leading CAs such as Sectigo, Comodo, DigiCert, GeoTrust, and RapidSSL. My focus is on SSL/TLS, certificate management, PKI, code signing, email signing, and certificate automation. I also share practical insights on choosing and managing DV, OV, EV, wildcard, and multi-domain certificates, along with ACME-based SSL automation.
