ISO 20000-1

ISO 20000-1
Compliance, Quantum-Ready.

ISO/IEC 20000-1 is the international standard for an IT Service Management System (SMS), governing how IT services are planned, designed, delivered and continually improved. QSECS applies its rigorous change and configuration disciplines to make post-quantum cryptographic migration a controlled, low-risk service change rather than a disruptive overhaul. The result is quantum-ready compliance delivered with the same predictability your business expects from every other managed service.

Understanding ISO 20000-1

ISO/IEC 20000-1 defines the requirements for establishing, operating and improving a Service Management System that delivers IT services aligned to business and customer needs.

At its heart, ISO/IEC 20000-1 establishes a Service Management System: a coordinated set of policies, objectives, processes and resources that an organisation uses to direct and control its IT services. It frames service management around a full lifecycle — planning and design of new or changed services, transition into the live environment, day-to-day delivery, and continual improvement — so that every service is governed consistently from concept through retirement.

The standard codifies the core processes that keep services reliable, including incident, problem, change, configuration, release and service-level management. These disciplines align closely with widely adopted ITIL practices, giving organisations a recognised, auditable way to manage risk and maintain service quality. By integrating measurement, control and feedback at every stage, ISO/IEC 20000-1 assures that IT services remain dependable, predictable and genuinely aligned to the customers and business outcomes they support.

What ISO 20000-1 Covers

The Service Management System and its governing policy, objectives and leadership commitments

Service design, transition and delivery across the full service lifecycle

Incident and problem management to restore service and eliminate root causes

Change, configuration and release management for controlled, traceable service changes

Service-level management and continual service improvement of performance and quality

The Quantum Clock Is Ticking

NIST projects that quantum computers capable of breaking RSA-2048 could arrive by 2030-2035, and its post-quantum migration guidance sets that window as the deadline to deprecate today's vulnerable cryptography. Adversaries are already running "Harvest Now, Decrypt Later" campaigns. Your compliance program has to evolve before the deadline — not after.

Staying Current

How QSECS Keeps Your ISO 20000-1 Future-Proof

QSECS manages your post-quantum transition through proven service management discipline, treating cryptographic modernisation as a planned, controlled change within your existing SMS.

We track every cryptographic asset — certificates, keys, libraries and protocols — as configuration items in your configuration management database (CMDB), giving full visibility of what must be migrated

We run PQC migration to NIST standards (FIPS 203, 204 and 205) as governed change and release management, with defined approvals, testing and rollback plans so live services stay protected

We sequence the migration roadmap as a managed release schedule so high-risk systems are remediated first and the transition completes well before the NIST 2030-2035 deadline

We protect SLA continuity throughout the transition, scheduling cryptographic changes within agreed maintenance windows so availability and performance targets are upheld

We embed continual service improvement, reviewing metrics and feeding lessons back into your SMS so quantum readiness becomes part of ongoing, auditable service management
