A globally recognized standard defining requirements for an Information Security Management System.

What is ISO 27001?

ISO 27001 is a globally recognized standard that defines the requirements for an information security management system (ISMS). An ISMS is the set of policies, procedures, and controls an organization uses to manage security risks to its information assets.

Published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), the standard was most recently updated in 2022. ISO 27001 doesn't prescribe specific technical controls. Instead, it requires you to:

  1. Assess your risks. Identify what information assets you have, what threats they face, and what the impact of a breach would be.
  2. Implement appropriate controls. Select and implement controls to address those risks, guided by Annex A of the standard (which lists 93 controls across organizational, people, physical, and technological categories).
  3. Monitor and improve. Continuously evaluate whether your controls are working and adapt as your risk landscape changes.

Certification is granted by an accredited third-party audit body after a two-stage audit process. Stage 1 reviews your documentation and ISMS design. Stage 2 evaluates whether the ISMS is operating effectively in practice. Certification is valid for three years, with annual surveillance audits to confirm ongoing compliance.

Why ISO 27001 matters for startups

If your startup sells to customers outside the United States, or to multinational companies, ISO 27001 is often the compliance framework they expect to see. While SOC 2 is the dominant standard in North America, ISO 27001 is the global default.

Here's why it deserves consideration:

  1. International credibility. ISO 27001 is recognized in over 160 countries. For startups selling into European, Asian, or Latin American markets, it carries more weight than SOC 2, which is primarily a North American framework. According to Sprinto, many international enterprise buyers treat ISO 27001 as a baseline requirement, not a differentiator.
  2. Increasingly expected alongside SOC 2. For startups selling globally, the question is often not "SOC 2 or ISO 27001?" but "both." Many enterprise procurement teams want ISO 27001 for international assurance and SOC 2 for the U.S. market. The good news: there's significant overlap between the two frameworks, so pursuing both is less than double the effort.
  3. Risk-based, not checklist-based. ISO 27001 requires you to start with your specific risks and build controls around them. This means your ISMS is tailored to your actual threat landscape, not a generic checklist. For startups, this is actually more practical than it sounds: you focus your security investment on the areas that matter most for your business.
  4. Costs are accessible. According to SecureLeap, ISO 27001 certification costs for startups range from $10,000 to $50,000 depending on scope and company size. That includes the readiness assessment, internal audit, and certification audit. HighTable projects these costs rising approximately 20% in 2026 due to increased demand for qualified auditors and the transition to the 2022 version of the standard.

How Fencer helps with ISO 27001

Fencer supports ISO 27001 compliance by automating the continuous monitoring and evidence collection that the standard requires. Rather than treating your ISMS as a document you dust off before audits, Fencer keeps your security controls active and auditable every day.

What makes Fencer's approach different:

  • Control mapping. Every finding from Fencer's vulnerability scanning, CSPM, and EASM capabilities maps to the specific ISO 27001 Annex A controls it relates to. You can see at a glance which controls are covered, which have open findings, and where gaps exist.
  • Continuous monitoring evidence. ISO 27001 requires ongoing monitoring and review of your ISMS. Fencer's continuous scanning generates time-stamped evidence of control effectiveness that auditors can verify, replacing the manual evidence-gathering sprint before surveillance audits.
  • GRC integration. Fencer syncs findings and evidence to your GRC tool, keeping your ISO 27001 compliance dashboard current alongside your SOC 2 evidence if you're pursuing both frameworks.
