If your tech company sells to enterprise customers, international markets, or regulated industries, you've probably heard the question: "Are you ISO 27001 certified?" It's no longer a differentiator — it's a requirement. In 2026, ISO 27001 has become the global standard for demonstrating that your organization takes information security seriously.
The ISO 27001 certification process can feel intimidating. There are 93 controls across 4 themes, a mandatory risk assessment framework, and a two-stage audit process. But for tech companies, the certification is more achievable than most founders realize — especially with modern compliance automation tools that can streamline the evidence collection process.
This guide covers everything you need to know about getting ISO 27001 certified: the step-by-step process, the cost and timeline, how to implement an Information Security Management System (ISMS), and how ISO 27001 compares to SOC 2 (spoiler: they're complementary, not competing).
What Is ISO 27001 and Why Should Your Tech Company Care?
ISO 27001 is an international standard published by the International Organization for Standardization (ISO) that specifies the requirements for an Information Security Management System (ISMS). It provides a systematic approach to managing sensitive company information, ensuring it remains secure through risk management processes, policies, and controls.
Unlike a one-time security assessment, ISO 27001 requires ongoing maintenance and continuous improvement. The certification is valid for three years, with annual surveillance audits to verify that your ISMS remains effective.
For tech companies, the benefits of ISO 27001 certification include:
- Global market access: Many European and Asian enterprises require ISO 27001 certification from vendors — it's often more important than SOC 2 in international markets
- Competitive differentiation: In a crowded SaaS market, ISO 27001 certification signals that you've implemented rigorous security practices
- Risk reduction: The ISMS framework forces you to identify, assess, and treat security risks systematically
- Process improvement: ISO 27001's continuous improvement cycle means your security practices get better over time, not worse
- Legal and regulatory compliance: ISO 27001 maps to GDPR, HIPAA, and other regulatory frameworks, simplifying multi-standard compliance

ISO 27001 vs SOC 2: Key Differences
This is the most common question I get from tech companies. While ISO 27001 and SOC 2 overlap significantly in the controls they evaluate, they serve different purposes and markets.
ISO 27001 is a formal certification. You pass or fail based on whether your ISMS meets the standard's requirements. The output is a certificate valid for three years, recognized globally. It's an international standard (ISO) and is particularly important for European and Asian markets.
SOC 2 is an attestation report. An auditor evaluates your controls against the AICPA's Trust Services Criteria and issues a detailed report describing what they found. It's not a pass/fail — the report includes both compliant areas and exceptions. SOC 2 is primarily a North American framework.
Many tech companies pursue both certifications to satisfy global customer requirements. The good news is that the evidence and controls you build for one framework can be largely reused for the other. Compliance platforms like Vanta, Drata, and Secureframe support both standards simultaneously, making dual certification more achievable than ever.
See our SOC 2 compliance checklist for a detailed guide on the SOC 2 process.

The ISO 27001 Certification Process: Step by Step
Here's the exact process for getting ISO 27001 certified. The timeline assumes you're starting from scratch with no existing formal security program.
Step 1: Scope Definition and Initiation (Week 1–3)
Define the boundaries of your ISMS. This is one of the most important decisions you'll make. Scope too broadly, and you'll create an unmanageable certification project. Scope too narrowly, and customers may not find your certification credible.
Most tech companies scope their primary product or platform, the infrastructure that supports it (AWS, GCP, Azure accounts), and the teams involved in development and operations. Document your scope clearly in the ISMS scope document — your auditor will review this first.
You'll also need executive buy-in at this stage. ISO 27001 requires top management commitment (Clause 5.1), and the certification process will demand resources from across your organization. Make sure your leadership understands what's required before you begin.
Step 2: Risk Assessment and Treatment Plan (Week 3–6)
ISO 27001 is fundamentally a risk management standard. You must establish a risk assessment methodology, identify information security risks, evaluate their likelihood and impact, and determine how to treat them.
Your risk assessment should cover:
- Confidentiality, integrity, and availability risks to information assets
- Risks from business processes, technology, and people
- Risks from third-party vendors and partners
- Legal and regulatory compliance risks
For each identified risk, you'll document a treatment plan: accept, mitigate, transfer (e.g., cyber insurance), or avoid. Risks that you choose to mitigate become requirements for your control environment.
Step 3: Statement of Applicability and Control Selection (Week 6–8)
The Statement of Applicability (SoA) is the core document of your ISMS. It lists all 93 controls from Annex A and states whether each control is applicable to your organization and, if so, how it's implemented.
Controls that are not applicable must be justified. For example, if you don't have physical offices, you may not need physical security controls (Section 11). If you don't process payment cards, PCI DSS-specific controls may not apply.
Your SoA is one of the first documents your Stage 1 auditor will review, so take time to get it right. A well-documented SoA demonstrates that you've thought carefully about your security posture.
Step 4: ISMS Implementation — Policies, Processes, and Controls (Week 8–20)
This is the most intensive phase. You'll implement the policies, processes, and technical controls documented in your SoA. Key implementation areas for tech companies include:
- Security policies: Information security policy, access control policy, acceptable use policy, incident response policy, business continuity policy
- Access controls (Annex A.9): SSO, MFA, role-based access control, quarterly access reviews, privileged access management
- Cryptography (A.10): Encryption at rest and in transit, key management, certificate management
- Physical security (A.11): Office security, equipment security, clear desk policy
- Operations security (A.12): Change management, capacity management, malware protection, log monitoring
- Communications security (A.13): Network security, VPN requirements, email security
- System acquisition and development (A.14): Secure SDLC, code review requirements, staging environments
- Supplier relationships (A.15): Vendor risk management, third-party security assessments
- Incident management (A.16): Incident detection, reporting, response procedures, and post-incident reviews
- Business continuity (A.17): BCP documentation, DR testing, backup procedures
Compliance automation platforms like Vanta, Drata, and Secureframe can dramatically reduce the effort by automating evidence collection and providing policy templates.
Step 5: Internal Audit and Management Review (Week 20–24)
Before inviting the external auditor, you must conduct an internal audit of your ISMS. This is a mandatory requirement of the standard (Clause 9.2). The internal audit verifies that your controls are implemented and operating effectively.
You'll also need a management review meeting (Clause 9.3) where leadership evaluates the ISMS's performance, reviews audit findings, and approves improvement actions. Document this meeting with minutes and action items — your external auditor will want to see evidence.
I recommend using an external consultant or a different team member for the internal audit to ensure objectivity. If you identify control gaps during the internal audit, fix them before the external audit begins.
Step 6: Stage 1 and Stage 2 External Audits (Week 24–30)
The external certification audit happens in two stages:
Stage 1 Audit: The auditor reviews your documentation — ISMS scope, risk assessment, Statement of Applicability, security policies, and internal audit records. This is a document review that verifies you're ready for the on-site audit. If the Stage 1 audit identifies major gaps, you'll need to address them before proceeding.
Stage 2 Audit: The on-site audit (which may be remote or in-person depending on the auditor). The auditor tests your controls, interviews employees, and verifies that your ISMS is operating effectively. They'll review evidence, inspect systems, and validate that what's documented matches what's actually happening.
If the Stage 2 audit identifies non-conformities, you'll have a defined period (typically 30–90 days) to implement corrective actions. Once all non-conformities are resolved, you receive your certification.
Step 7: Surveillance Audits and Recertification (Ongoing)
ISO 27001 certification is valid for three years, with annual surveillance audits in years one and two, and a full recertification audit in year three.
Surveillance audits are less intensive than the initial certification audit — they focus on verifying that your ISMS continues to operate effectively and that any previously identified non-conformities have been addressed. But they still require preparation and evidence collection.
Ongoing maintenance includes:
- Annual internal audits and management reviews
- Continuous risk assessment updates
- Regular policy reviews and updates
- Evidence collection from your security tools (SIEM, endpoint protection, vulnerability scanner)
- Incident documentation and post-incident reviews
I recommend budgeting 4–8 hours per month for ongoing ISO 27001 maintenance once your ISMS is established.

ISO 27001 Cost and Timeline for Tech Companies
Here's what you can expect to spend, based on recent certification projects at tech companies of various sizes:
| Company Size | Timeline | Total Cost (3 years) | Key Cost Drivers |
|---|---|---|---|
| 1–20 employees | 3–6 months | $25k–$45k | Compliance platform ($10k/yr), audit ($5k–$10k) |
| 20–200 employees | 5–8 months | $45k–$80k | Consultant ($15k–$30k), compliance platform, audit ($10k–$15k) |
| 200+ employees | 8–20+ months | $80k–$200k+ | Dedicated compliance team, multiple audits, broader scope |
These costs include auditor fees, consultant support, compliance automation platform subscriptions, and internal resource time. The internal time cost is often the largest hidden expense — expect to dedicate at least one team member part-time (10–15 hours/week) during the implementation phase.

Common Challenges Tech Companies Face
Based on my experience advising companies through ISO 27001 certification, here are the most common pitfalls — and how to avoid them.
- The checkbox mentality: Treating ISO 27001 as a paperwork exercise rather than a genuine security improvement. Auditors can tell when you're going through the motions, and it leads to failed surveillance audits. Build controls that actually work for your team.
- Scope creep: Including too many business units or systems in your initial scope. Start with your core product and supporting infrastructure. You can expand the scope in subsequent certification cycles.
- Underestimating evidence requirements: In 2026, screenshots are no longer sufficient evidence. Auditors expect full logs, automated evidence trails, and verifiable records. Compliance automation platforms are essential for meeting this standard.
- Leadership disengagement: Treating ISO 27001 as an "IT project" rather than an organizational priority. Certification requires resources from HR (background checks, training records), Legal (contracts, NDAs), and Operations (BCP, physical security).
- Neglecting continuous improvement: ISO 27001 requires ongoing maintenance. If you stop actively managing your ISMS after certification, you'll fail the surveillance audit. Budget for the recurring effort, not just the initial implementation.

Frequently Asked Questions About ISO 27001
How long does ISO 27001 certification take?
For a typical tech company, expect the initial certification process to take 3–8 months depending on your organization's size, complexity, and existing security posture. Small startups with strong security foundations can move faster. Larger organizations with complex infrastructure require more time for full implementation.
Can I get ISO 27001 certified without a consultant?
Yes, but I recommend using a compliance platform (Vanta, Drata, Secureframe) at minimum. These tools provide policy templates, automated evidence collection, and gap assessments that guide you through the process. A consultant can accelerate the timeline by 2–3 months by helping you avoid common mistakes, but platforms make DIY certification more achievable than ever.
Do I need ISO 27001 if I already have SOC 2?
Not necessarily — it depends on your target market. If you primarily sell to North American enterprises, SOC 2 is usually sufficient. If you're selling in Europe, Asia, or to global enterprises, ISO 27001 is often required. Many compliance platforms support both frameworks simultaneously, so you can achieve both with incremental effort rather than starting from scratch.
What happens during an ISO 27001 surveillance audit?
Surveillance audits are shorter and less intensive than the initial certification. The auditor focuses on a sample of your controls, verifies that previously identified non-conformities have been addressed, and reviews changes to your ISMS since the last audit. They typically take 1–2 days and can be conducted remotely.
What's the difference between ISO 27001 and ISO 27002?
ISO 27001 is the certification standard — it specifies the requirements for establishing, implementing, maintaining, and improving an ISMS. ISO 27002 is a complementary standard that provides implementation guidance for the 93 controls listed in Annex A of ISO 27001. Think of ISO 27001 as the "what" (requirements) and ISO 27002 as the "how" (implementation guidance).
Conclusion
ISO 27001 certification is a significant undertaking, but for tech companies with global ambitions, it's one of the most valuable investments you can make. The certification process forces you to build a systematic, continuously improving approach to information security that benefits your customers, your team, and your business.
The key is to approach certification strategically: start with a clear scope, invest in compliance automation early, and treat certification as the beginning of your security journey, not the end. The ISMS you build will make your product more secure, your operations more resilient, and your business more credible in the global market.
If you're deciding between ISO 27001 and SOC 2, consider your target markets. North American customers typically ask for SOC 2. European and Asian customers prefer ISO 27001. Many successful SaaS companies pursue both — and with modern compliance platforms, dual certification is more achievable and cost-effective than ever.
