Public Key Infrastructure - SITS
Enterprise PKI & X.509 Certificates at a Glance

From verifying emails, identities, or applications to your employees company badge – it all requires digital certificates issued and managed through an Enterprise Public Key Infrastructure (PKI) which act like a “digital ID”.

They ensure only authorized identities can access your company’s data and services. The demand for X.509 certificates significantly increases when you work in the cloud, implement modern security architectures on-premise, or introduce IoT-based solutions. With keyon true-Xtender, your Enterprise PKI, and SITS consulting, you can issue certificates according to the X.509 standard and verify the identity of persons, devices, or services. The SITS offering provides your company with:

  • Authentication: Issuing X.509 certificates to verify mobile devices, Windows PCs, smartcard log-ons, network accesses, emails, web services, and digital signatures.
  • Certificate management: Managing the automatically issued internal company certificates via a dashboard.
  • Expiry and revocation: When a user is deleted or a certificate expires, keyon true-Extend automatically deletes or revokes the certificate.

The Risks of Digital Communication

Unencrypted and unsigned communication: A gateway for breaches

Cyber-attacks via fake websites, emails, or identities are an increasing threat. To prevent security breaches and data leaks, businesses need to ensure that only authorized and validated entities can access their IT.

Only the safe creation and thorough management of X.509 certificates ensure secure digital communication.

Your Business Challenge
Your Business Challenge
Without X.509 certificates, businesses face several risks:

  • Unsafe communication: Without X.509 certificates, there's a risk that communication between entities remains unencrypted—a gateway for hackers.
  • Lack of authentication: Without X.509 certificates, verifying the identity of a person, computer, or website becomes challenging, increasing the risk of attacks and identity theft.
  • No integrity assurance:509 certificates help ensure data integrity, preventing unnoticed manipulation during transmission.
  • Risk of ``Man in the Middle`` attacks: Without X.509 certificates, ``MitM`` attacks, where an attacker intercepts communication pretending to be one of the parties, become likely.

Frequently Asked Questions

X.509 is a standard for public key certificates, digital documents that securely link key pairs with identities—such as websites, individuals, or organizations. X.509 certificates contain information like the identity's name, their public key, and the certificate's issuer. Their main role within a Public Key Infrastructure (PKI) is to authenticate the public keys in use and verify that they belong to their holder. Moreover, each certificate includes essential information, such as the certificate's purpose and validity.

The primary use of X.509 certificates is to ensure security and authentication in internet communication. They are utilized in SSL/TLS connections, email encryption and authentication, digital signatures, and other security-relevant applications.

During the validation of an X.509 certificate, a trusted Certification Authority (CA) within a PKI checks the certificate's signature to ensure it is valid and has not been tampered with. Then, the CA determines whether the certificate is currently valid and can be used for its intended purpose.
