The Core Mission: Securing Digital Trust

DigiCert’s fundamental mission revolves around fortifying digital trust. In an era plagued by sophisticated cyber threats, verifying identities and ensuring secure data transmission are paramount. DigiCert achieves this through its robust Public Key Infrastructure (PKI) solutions, serving as a pillar of authentication and encryption across the internet.

The Foundation of Trust: PKI and Digital Certificates

Public Key Infrastructure (PKI) is the unseen architecture that enables secure digital communication and identity verification. It’s a system comprising hardware, software, policies, and procedures that manage digital certificates and public-key encryption. At its core, PKI allows for the secure exchange of information over an untrusted network like the internet. DigiCert, as a global Certificate Authority, is a crucial component of this infrastructure.

Digital certificates are the verifiable credentials issued within a PKI. Think of them as digital ID cards that bind a public key to an identified entity. When you visit a website, for instance, its digital certificate, issued by a trusted CA like DigiCert, confirms its identity and enables your browser to establish an encrypted connection. This process is automatic and happens in milliseconds, giving users peace of mind that they are interacting with the legitimate site and that their data is protected. These certificates come in various forms, each tailored for specific security needs, but all share the common goal of establishing trust and securing digital interactions.

SSL/TLS Certificates: The Web’s Shield

The most recognizable offering from DigiCert, and indeed from any major CA, are SSL/TLS certificates. These are the digital linchpins that activate the padlock icon in your browser’s address bar and change “http” to “https,” signaling a secure connection. SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols designed to provide communication security over a computer network. When a website uses an SSL/TLS certificate, it achieves two critical functions:

Encryption: All data exchanged between your browser and the website server is encrypted, making it unreadable to anyone trying to intercept it. This protects sensitive information like credit card numbers, login credentials, and personal data from eavesdropping.
Authentication: The certificate verifies the identity of the website. It assures users that they are communicating with the genuine website and not a fraudulent impostor attempting a phishing attack.

DigiCert offers different validation levels for SSL/TLS certificates, each providing varying degrees of identity assurance:

Domain Validated (DV) Certificates: These are the simplest to obtain, verifying only the ownership of the domain name. While they enable encryption, they offer minimal identity assurance beyond confirming control of the domain itself.
Organization Validated (OV) Certificates: OV certificates require more rigorous vetting, verifying not only domain ownership but also the legitimate existence of the organization or business behind the website. This adds a layer of trust, as users can see the organization’s name within the certificate details.
Extended Validation (EV) Certificates: EV certificates are the highest standard for website identity verification. They involve a comprehensive and standardized vetting process to confirm the legal, operational, and physical existence of the entity. Historically, these displayed the organization’s name prominently in a green address bar, though browser interfaces have evolved. EV certificates provide the strongest assurance of a website’s authenticity, crucial for high-value transactions and sensitive data handling.

By offering this spectrum of SSL/TLS certificates, DigiCert empowers organizations to choose the level of trust and security appropriate for their operations, ranging from personal blogs to large e-commerce platforms and financial institutions.
