What Is ISO 27001?
ISO/IEC 27001 is the internationally recognized standard for Information Security Management Systems (ISMS). It sets out requirements for building, running, maintaining, and continuously improving a systematic approach to managing information security risks. Certification comes from an accredited third-party body after a two-stage audit. It’s the dominant information security standard in Europe and Asia-Pacific, and it’s increasingly required by multinational enterprise customers for their US-based vendors.
Here’s the thing: ISO 27001 isn’t just a policy document. The standard demands that you actually operate the controls, not just write them down. That’s what makes it credible, and what makes it genuinely difficult to achieve without a managed services partner who can keep those controls running day to day.
Value Proposition: Why Choose AdVran for ISO 27001?
ISO 27001 certification signals to global partners, clients, and regulators that your organization takes information security seriously. But building and maintaining an ISMS requires ongoing operational discipline, not just a policy library.
1. ISMS Design and Operation
We help you design an Information Security Management System tailored to your organization’s risk profile and business context. Then we operate the technical controls that make it real, from access management to incident response.
2. Annex A Controls Implementation
The 2022 revision includes 93 controls across organizational, people, physical, and technological domains. We set up and operate the technological controls, and support your teams on the organizational and people-based ones.
3. Risk Assessment and Treatment
ISO 27001 centers on risk-based decision making. We run regular risk assessments, keep a risk treatment plan current, and make sure controls are proportionate to identified risks. Good security and good business sense point the same direction.
4. Internal Audit Support
We support your internal audit process with evidence collection, control testing, and gap remediation. When your certification body runs the external audit, the evidence is organized and the controls are demonstrably working.
5. Continual Improvement
ISO 27001 requires continual improvement of the ISMS. We give you quarterly security reviews, trend analysis, and improvement recommendations, so your certification stays valid and your security posture keeps getting stronger.
Frequently Asked Questions About ISO 27001 Compliance
What is ISO 27001 and who needs it?
ISO 27001 is the international standard for managing information security through a documented ISMS. It’s required or strongly preferred by multinational enterprise customers, European Union business partners (particularly post-GDPR), and companies in regulated industries globally. California technology companies expanding into European markets or pursuing contracts with European enterprises frequently need ISO 27001 certification to satisfy procurement requirements.
What is the difference between ISO 27001 and SOC 2?
ISO 27001 is an international standard certifying that your ISMS meets defined requirements, audited by an accredited certification body, resulting in a certificate. SOC 2 is an AICPA attestation report focused on specific trust service criteria for cloud and technology service providers, primarily used in North American markets. ISO 27001 has broader international recognition; SOC 2 is more common for US B2B SaaS and managed service contracts. Many companies pursue both at once because the control overlap is significant.
How long does ISO 27001 certification take?
ISO 27001 certification typically takes 6-18 months from initial gap assessment to certificate issuance, depending on the organization’s starting maturity. The process includes: gap assessment, ISMS design and documentation, control setup, internal audit, management review, Stage 1 audit (documentation review), Stage 2 audit (effectiveness), and certificate issuance. We guide clients through each phase and manage certification body coordination.
What are the 93 ISO 27001 Annex A controls?
ISO 27001:2022 Annex A contains 93 controls organized into four themes: Organizational (37 controls), People (8 controls), Physical (14 controls), and Technological (34 controls). Organizations complete a Statement of Applicability (SoA) to document which controls apply, which are set up, and which are excluded with justification. The 2022 update added 11 new controls covering threat intelligence, cloud security, data masking, and secure development.
Can AdVran help California companies achieve ISO 27001 certification?
Yes. We provide end-to-end ISO 27001 services including initial gap assessment, ISMS documentation, Annex A control setup, internal audit execution, and support through Stage 1 and Stage 2 certification audits. For California companies with existing SOC 2 programs, ISO 27001 can often be achieved with incremental effort because the control foundations overlap significantly. We coordinate directly with accredited certification bodies throughout the process.
