Why choose Ascertia PKI-as-a-Service?

  • Deploy fast, stay compliant

    Stand up a dedicated PKI in days, aligned with eIDAS, NIST, and industry best practices, without hiring or training a Certificate Authority (CA) operations team.

  • Trusted technology foundation

    Built on the same ADSS CA/PKI Server trusted worldwide by governments, banks and telecom providers—now available as a fully managed service.

  • Complete lifecycle management

    Issue, renew, revoke, and audit certificates for people, devices and workloads, at scale and under your full policy control.

  • Seamless integration

    Support for SCEP, EST, ACME, OCSP, CRL, RFC-compliant timestamps and long-term validation (LTV), plus rich APIs for automation and DevOps pipelines.

  • Expert-led operations

    Ascertia’s PKI specialists operate and monitor the service, so you can focus on delivering secure digital services while retaining governance and control.

What you get

Managed PKI core

  • Dedicated issuance hierarchies (Root and Sub-CA options) with policy templates
  • OCSP and CRL validation services and secure timestamping
  • Role-based administration, audit logging and compliance reporting
  • Hardware Security Module (HSM) protection and key ceremonies (on request)

Identity & device at scale

  • People and workforce certificates: authentication, email, and document signing
  • Device and IoT identities: Wi-Fi, VPN (802.1X), mTLS, and code signing
  • Workload and machine identities: containers, services, and APIs

Automation & DevOps

  • Zero-touch enrolment with SCEP, EST and ACME
  • REST/SOAP SDKs for custom workflows and integrations

Operations you can trust

  • High-availability deployment with continuous monitoring
  • Backup, restore and disaster recovery readiness
  • Controlled change management and scheduled maintenance

Common use cases

  • Zero-trust network access – mTLS, device identity, Wi-Fi/VPN 802.1X
  • Document and data signing – citizen and business e-signatures, eSeals, LTV
  • Cloud workload security – Kubernetes, service meshes, API gateways
  • IoT onboarding at scale – factory provisioning, lifecycle renewal and revocation

How it works

  • Design and onboarding – Map trust policies, certificate profiles and enrolment flows.
  • CA build – Configure your dedicated hierarchy on ADSS CA/PKI Server with HSM-backed keys.
  • Connect and automate – Integrate via SCEP, EST, ACME, or Admin Console/APIs.
  • Operate and assure – Ascertia manages operations; you retain policy governance.

Security and compliance

  • Audit readiness – Comprehensive logging, compliance reports and evidence packs
  • Sovereignty options – Choose data residency and HSM location to meet regulatory needs

Integrations

  • Microsoft / Azure AD / Intune (SCEP/PKCS #12 delivery)
  • MDM/UEM platforms (SCEP/EST)
  • Web servers, proxies, load balancers (ACME/mTLS)
  • CI/CD and code signing pipelines
  • SigningHub & ADSS Signing Server for end-to-end digital signature solutions.

Service tiers

  • Essentials – Single Sub-CA, up to 50k active certificates, standard protocols, shared ops window
  • Professional – Multiple Sub-CAs, up to 250k active certificates, dedicated HSM partition, enhanced reporting
  • Enterprise – Custom hierarchy (including offline Root), multi-region HA, dedicated SLAs, support

Migration made simple

Already running an internal CA or another managed PKI? Ascertia help you:

  • Transition issuance policies and profiles
  • Import or re-key Sub-CAs
  • Switch enrolment endpoints with minimal downtime
  • Run parallel environments with controlled cut-over and revocation plans
