ISO 9001:2015

ISO 9001:2015 and Cybersecurity/IT


Origin and Development


ISO 9001:2015 is a quality management system standard developed by the International Organization for Standardization (ISO), a global federation of national standards bodies. However, it's important to clarify that ISO 9001:2015 is not specifically a cybersecurity or IT certification—it's a general quality management standard applicable to any organization regardless of industry. The standard was released in 2015 as the fifth revision of ISO 9001, which was first published in 1987. For cybersecurity specifically, ISO created ISO/IEC 27001, which is the actual information security management system standard.


Industry Value and Importance


ISO 9001:2015 is valued across industries because it demonstrates an organization's commitment to consistent quality management, customer satisfaction, and continuous improvement. When applied to IT and cybersecurity contexts, it helps organizations establish systematic processes for service delivery and quality assurance. However, for cybersecurity-specific certification, organizations typically pursue ISO/IEC 27001, which directly addresses information security controls, risk management, and data protection. Both certifications are internationally recognized and often required for government contracts, enterprise partnerships, and demonstrating due diligence to customers and stakeholders.

Cyber Essentials Plus

Cyber Essentials Plus


Origin


Cyber Essentials Plus was created by the UK Government in 2014 in collaboration with the National Cyber Security Centre (NCSC), which is part of GCHQ. The scheme was developed in response to the growing threat of cyber attacks against UK businesses and organizations. It was designed to help organizations of all sizes implement basic cybersecurity controls to protect against the most common internet-based cyber threats, with the "Plus" variant including hands-on technical verification by qualified assessors.


Industry Value


Cyber Essentials Plus is highly valued because it provides verified assurance that an organization has implemented fundamental cybersecurity controls effectively. Unlike the standard Cyber Essentials self-assessment, the Plus certification requires external testing and vulnerability scanning, making it more rigorous and credible. It's increasingly required for UK government contracts involving sensitive information and is recognized by insurance providers, clients, and partners as evidence of a serious commitment to cybersecurity. The certification helps organizations demonstrate due diligence, reduce cyber risk, and differentiate themselves in competitive bidding situations.

CREST

CREST Cybersecurity Certification


Origin


CREST (Council of Registered Ethical Security Testers) was established in 2006 in the United Kingdom by a group of cybersecurity professionals and industry representatives. It was created to address the growing need for standardized, recognized qualifications in penetration testing and cybersecurity services. The organization emerged from concerns about the quality and professionalism of security testing services, aiming to provide a framework that would certify both individual practitioners and the companies that employ them.


Industry Value


CREST certifications are highly valued in the cybersecurity industry because they demonstrate a practitioner's technical competence and adherence to professional ethical standards. Many government agencies, financial institutions, and large corporations specifically require CREST-certified professionals when procuring penetration testing or security assessment services. The certification provides assurance to employers and clients that certified individuals have been independently verified to possess the necessary skills and knowledge, and that they follow established codes of conduct. This makes CREST credentials particularly important for cybersecurity professionals working in regulated industries or seeking to work with organizations that have stringent security requirements.
