Comprehensive Public Key Infrastructure (PKI), SSL/TLS certificate management, Certificate Authority (CA) services, code signing, and digital identity solutions for enterprises, vehicles, and IoT devices.
How your PKI is operated matters as much as what it secures. Schutz IT delivers enterprise PKI in three models so your team can match control, ownership and operational responsibility to its requirements.
We operate certificate infrastructure, lifecycle processes and policy controls on your behalf.
A dedicated Certificate Authority under your governance for internal systems, devices and services.
PKI as a Service with automated enrollment, renewal and hardware-backed key protection.
A scalable enterprise PKI platform with seamless integration into Microsoft Intune, Enrollment over Secure Transport (EST), Automated Certificate Management Environment (ACME), and JAMF, enabling automated certificate enrollment and management across Windows, macOS, iOS, and Linux devices for secure identity and access control.
Implement Double Key Encryption (DKE) for Microsoft 365 to ensure zero-trust data protection. Our solution enables organizations to maintain exclusive control over encryption keys while leveraging Microsoft Purview Information Protection for regulatory compliance and data sovereignty.
A robust automotive PKI framework securing vehicle-to-cloud communications, onboard diagnostics access, and vehicle-to-everything (V2X) interactions. Enables trusted digital identity for ECUs, telematics control units, and external systems.
PKI-based Plug and Charge solution aligned with ISO 15118, enabling secure, seamless, and automated EV charging sessions. Ensures mutual authentication between EVs and charging infrastructure with trusted digital certificates.
End-to-end certificate lifecycle management platform offering discovery, issuance, renewal, and revocation across hybrid environments. Integrates with existing IT infrastructure to reduce outages and improve compliance through centralized visibility and automation.
Comprehensive code signing and firmware signing services that safeguard the integrity and authenticity of software and device firmware. Includes key protection with HSM integration, policy enforcement, and signing workflow automation.
Machine and workload trust is only half of enterprise identity assurance. Pairing your PKI programme with customer identity and access management (CIAM) extends the same governed trust model to the people signing in to your applications.
X.509 certificates are the standard format for digital certificates used in PKI implementations. They contain the public key of an entity, identity information, validity periods, and are digitally signed by a Certificate Authority to establish trust.
The foundation of PKI is asymmetric cryptography, utilizing mathematically related key pairs. The private key remains secret with the owner, while the public key is distributed freely via certificates to enable secure communications and digital signatures.
Code signing applies digital signatures to software and firmware to verify authenticity and integrity. This process uses PKI certificates to create a chain of trust from the developer to the end user, preventing unauthorized modifications.
Public Key Infrastructure (PKI) is a comprehensive security framework that manages digital certificates and public-key encryption to secure communications. It enables organizations to establish trust in digital environments through encryption, authentication, and digital signatures.
A Certificate Authority (CA) is a trusted entity that issues digital certificates, which verify that a particular public key belongs to a specific organization or device. The CA acts as a trusted third party that validates identities and issues certificates used in PKI environments for secure communications.
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) certificates serve the same purpose - establishing encrypted connections between web servers and browsers. TLS is the successor to SSL and offers improved security features. While SSL certificates is the common term, most modern implementations actually use TLS protocols, with TLS 1.3 being the latest version.
PKI is essential for enterprise security because it provides the foundation for secure digital communications. It enables secure email, secure web transactions, digital signatures, and strong authentication systems. With increasing digital transformation and remote work, PKI helps organizations protect sensitive data, verify identities, and maintain compliance with regulatory requirements.
In a PKI system, cryptographic keys work in pairs: a public key that can be shared with anyone, and a private key that must be kept secret. When someone wants to send an encrypted message, they use the recipient's public key to encrypt it. Only the recipient's private key can decrypt the message. For digital signatures, the process is reversed: the sender uses their private key to create the signature, and anyone can verify it using the sender's public key.
Code and firmware signing provide several benefits: they verify the identity of the software publisher, ensure code hasn't been altered since signing, protect against malware distribution, build trust with users, and meet compliance requirements. For IoT devices and automotive systems, firmware signing is crucial to prevent unauthorized firmware updates that could compromise security or functionality.
PKI is used to secure websites with SSL/TLS, authenticate users and devices, sign code and firmware, encrypt and digitally sign emails (S/MIME), enable mutual TLS between services and microservices, secure VPN and Wi-Fi access (EAP-TLS), issue smart card and PIV credentials, and underpin document signing, blockchain identities, and IoT/V2X communications. In every case PKI provides a verifiable identity and a tamper-evident cryptographic signature.
A complete PKI is built from: (1) a Root Certificate Authority that anchors trust, (2) one or more Issuing/Intermediate CAs that issue end-entity certificates, (3) a Registration Authority (RA) that validates requests, (4) Hardware Security Modules (HSMs) that protect private keys, (5) a Certificate Lifecycle Management (CLM) platform for discovery, enrolment and renewal, (6) revocation services (CRL and OCSP), (7) enrolment protocols such as ACME, SCEP and EST, and (8) the X.509 certificates and key pairs themselves.
Managed PKI means Schutz IT operates the day-to-day certificate infrastructure on your behalf, including Certificate Authority operations, issuance, renewal, revocation and policy management, while your team retains governance without maintaining the platform.
A public Certificate Authority issues certificates trusted broadly across the internet. Private PKI is dedicated to your organisation, giving you control over issuance policy for internal systems, devices and services that do not need public trust.
Yes, when properly architected. Cloud PKI uses certificate lifecycle management, hardware-backed key protection and enrollment protocols such as EST and ACME without requiring your team to host or maintain the underlying infrastructure.
Schutz IT covers the full certificate lifecycle, including Intune, EST, ACME and JAMF-integrated enrollment, Vehicle PKI, Double Key Encryption, and code and firmware signing, delivered as managed PKI, private PKI or cloud PKI.
Public Key Infrastructure (PKI) is a comprehensive security framework that manages digital certificates and public-key encryption to secure communications. It enables organizations to establish trust in digital environments through encryption, authentication, and digital signatures.
PKI provides the foundation for secure communications across networks by using a system of digital certificates, certificate authorities (CAs), and cryptographic keys to verify identities and protect data. This infrastructure is essential for:
Our Certificate Authority services establish a trusted hierarchy to issue, manage, and verify digital certificates for your organization, ensuring trusted identities across your digital ecosystem.
Secure websites and applications with our SSL/TLS certificates, providing encryption for data in transit and authentication of web services to prevent man-in-the-middle attacks.
Comprehensive management of cryptographic keys throughout their lifecycle, from generation and storage to rotation and retirement, with optional hardware security module (HSM) integration.
Protect software integrity with cryptographic signatures that verify code hasn't been tampered with and originates from a trusted source, essential for secure deployment pipelines.
