Cloud-based PKI certificates can protect applications hosted in the cloud. By utilizing an integrated certificate management solution, all digital certificates in the cloud and across the entire enterprise ecosystem can be automatically discovered, issued and updated. This ensures smooth operation of applications and eliminates the hassle of building and maintaining a PKI system on your own, allowing you to focus more on your core business.
Local PKI achieves identity authentication and data encryption for internal servers, systems, and employees of the enterprise by issuing private digital certificates. Enterprises utilizing a private PKI must provide necessary support in design, development, implementation, and maintenance, which can be time-consuming and entail additional costs.
By using PKI (public key infrastructure), enterprises can significantly improve the security level of their networks. There are three major benefits:
Public and private keys are used to encrypt and decrypt messages. Only the corresponding private key can decrypt the information encrypted by the public key. This is because the public key and the private key are a key pair generated by an asymmetric encryption algorithm. The key pair obtained by this algorithm is guaranteed to be unique in the world. When using this key pair, if a piece of data is encrypted with one of the keys, it must be decrypted with the other key. For example, if you encrypt data with a public key, you must decrypt it with a private key, and vice versa. Otherwise decryption will not be successful.
You can use a private CA to protect on-premises services (e.g., VPN, Wi-Fi, Wiki, etc.). However, building and maintaining a private CA can be both expensive and time-consuming. Therefore, you need to consider the cost of each approach before making a decision. Many reputable CAs offer hosted PKI solutions that can save you some of the hardware, software and personnel costs involved in building your own local PKI.
First, you need to consider your needs and evaluate enterprise application environment with the technologies you are using. We recommend starting with these five steps:
