Independent certification, where required, is performed by an appropriately accredited certification body.
Information Security Standard
ISO/IEC 27001.
Security by design.
ISO/IEC 27001 is the international standard for an Information Security Management System (ISMS). It provides a structured framework for managing information security risks and protecting the confidentiality, integrity and availability of information through people, processes and technology.
Certification can demonstrate an organisation's commitment to information security and help build confidence among customers, partners and stakeholders.
Information Security Management System
Risk-based controls. Defined responsibilities. Continual improvement.
Understanding the Standard
What is ISO/IEC 27001?
The standard provides a systematic way to establish, implement, maintain and continually improve an ISMS. It is designed to help organisations identify information security risks and manage them through appropriate, documented controls.
An International Standard
A globally recognised specification for establishing, maintaining and continually improving an information security management system.
A Risk Management Tool
Guides organisations in identifying, assessing and treating information security risks according to their context and risk criteria.
A Holistic Approach
Addresses information security through the combined management of people, policies, processes, technology and organisational responsibilities.
A Framework for the CIA Triad
Focuses on preserving the confidentiality, integrity and availability of information throughout its lifecycle.
Applicable Across Industries
Can be applied by organisations of different sizes and sectors, with the ISMS scope and controls tailored to their context.
Core Security Principles
The CIA Triad: three pillars of information security.
Select each principle to explore what it means and how it applies to protecting business information.
Explore the principles
Confidentiality
Information should only be accessible to authorised people, systems and processes. Appropriate access permissions, identity controls and data protection measures help reduce unauthorised disclosure.
Practical focus
Access control, least privilege, information classification and protection of sensitive data.
Business Value
Key benefits of ISO/IEC 27001.
An effectively implemented ISMS can support stronger information security practices while giving leadership a structured way to manage risks, responsibilities and improvement priorities.

Improved Security
Helps address risks associated with cyberattacks, data breaches, unauthorised access and human error through systematic controls.
02 / 05
Competitive Advantage
Certification, where achieved, can differentiate an organisation and provide additional assurance to customers and business partners.
03 / 05
Regulatory Alignment
Helps organise security controls and evidence that may support relevant legal, contractual and regulatory obligations.
04 / 05
Cost and Loss Prevention
Proactive risk management can help reduce the likelihood and impact of incidents and associated financial losses.
05 / 05
Enhanced Reputation
Demonstrates a structured commitment to information security and helps build confidence among customers and stakeholders.
Implementation Lifecycle
How ISO/IEC 27001 works.
Establishing an ISMS involves understanding risk, selecting appropriate treatments, managing the system and improving controls as the organisation changes.
Risk Assessment
Identify information assets, threats, vulnerabilities and potential impacts using defined risk assessment criteria.
Risk Treatment
Select appropriate risk treatment options and determine the controls needed to address identified risks.
Establish the ISMS
Define scope, policies, roles, procedures, evidence and management processes required to operate the system.
Monitor & Improve
Review performance, evaluate controls, conduct internal audits and track corrective actions and continual improvement.
Petabyte Consultancy Scope
Support for your ISO 27001 journey.
Consultancy activities can help your organisation understand its current position, identify gaps, establish required processes and prepare for an independent certification audit.
Gap Analysis
Review existing information security practices against applicable ISO/IEC 27001 requirements to identify areas that may require improvement.
Risk Assessment
Identify and evaluate information security risks, document findings and develop a risk treatment plan aligned with organisational priorities.
ISMS Implementation

Internal Audit & Certification Audit Support
Assist with audit preparation, evidence organisation, corrective action tracking and readiness activities within the agreed consultancy scope.
Documentation & Evidence
Documents commonly needed for ISO 27001.
Documentation should reflect the organisation's scope, risks, processes and applicable standard requirements. The following items are important examples, not an exhaustive list.
Build a documented, evidence-based ISMS.
Keep policies, risk records, control decisions and audit evidence consistent with the actual operation of your information security management system. Specific documented information depends on the applicable requirements and organisational context.
ISMS Policy
Documents the organisation's information security direction, commitments and policy framework.
Statement of Applicability (SoA)
Records applicable Annex A controls, their inclusion or exclusion rationale and implementation status as required.
Risk Assessment Report
Records assessed information security risks, evaluation results and the basis for risk decisions.
Risk Treatment Plan
Documents selected treatments, control actions, responsibilities and relevant approvals.
Internal Audit Records
Evidence of audit planning, findings, results and follow-up actions for the ISMS.
Industry Applications
Industries that can benefit from ISO 27001.
Any organisation managing valuable, sensitive or business-critical information can consider an ISMS. The scope and controls should reflect its specific assets, risks and operational requirements.
Finance
Banks, insurers and investment firms protecting financial and customer information.
Healthcare
Hospitals, clinics and medical research organisations handling sensitive health data.
IT Services
Software companies, cloud providers and technology businesses managing client data.
Manufacturing
Businesses protecting proprietary designs, intellectual property and operational data.
