If you’re running a business in IT services, software, data management, or even financial consulting, there’s a high chance you’ve come across two important ISO certifications: ISO 27001 Certification and ISO 22000 Certification.
These two standards sometimes get confused as being synonymous—but they’re used for very different things. One addresses service delivery; the other addresses information security. Both can, however, influence how your business runs, how customers perceive you, and whether or not you can get big contracts.
So, how do you determine which one your business requires—or whether both are worth exploring? Let’s run through all you need to know, step by step.

What Is ISO 20000 All About?
ISO 20000 is the international standard for IT Service Management Systems (ITSMS). It assists organizations in designing, delivering, and continually improving IT services—whether that’s managing in-house networks, operating help desks, or providing outsourced IT services to clients.
Here’s what ISO 20000 enables you to do:
Implement IT support processes (incident, change, problem management) on a standard basis.
Integrate your IT services with client expectations using SLAs.
Minimize downtime and response time.
Establish uniform documentation and reporting procedures.
ISO 20000 provides you with an organized, professional methodology for delivering IT services cost-effectively and with reliability. If you operate a Managed Service Provider (MSP) or a technical support department, having this certification demonstrates that you operate your business by international best practices.
Breaking Down ISO 27001: What Does It Cover?
ISO 27001 is the global standard for Information Security Management Systems (ISMS). This certification addresses how your business secures sensitive information, avoids breaches, and reacts to security incidents.
If you’re in fintech, SaaS, healthcare, or e-commerce, and you store or receive sensitive customer information, this is the ISO standard for you.
ISO 27001 benefits your company:
- Systematically identify and handle security threats.
- Establish controls on who uses data and systems.
- Establish encryption, authentication, and backup controls.
- Foster trust among customers and regulators.
- Comply with local and global data protection regulations.
- It's particularly helpful for businesses that deal with payment information, user accounts, or sensitive business data.
ISO 20000 vs ISO 27001: What's the Real Difference?
Now that you know what each standard accomplishes, let’s examine how they differ side by side.

Real-World Scenarios: Which Certification Fits Your Business?
Let’s consider some real-world examples to understand how these standards work:
- A Managed IT Services Company (MSP): You're providing outsourced helpdesk, remote support, and server management for several customers. You wish to minimize downtime, process support tickets better, and demonstrate to clients that your process-oriented. Begin with ISO 20000. This will standardize your delivery processes and enhance your credibility.
-
A Fintech Startup: You handle mobile payment products and have to cope with user information, bank credentials, and transaction records. Your biggest headache is regulatory compliance and customer information protection.
ISO 27001 is indispensable. It will make clients and investors sleep better at night. - A SaaS Platform: You provide a cloud solution that caters to various industries. You're working with data and services in parallel. Both certifications will serve you. ISO 20000 will enhance service performance; ISO 27001 will address your security requirements.
Can You Combine Both Certifications Together?
Yes—and most companies do. As a matter of fact, the standards support one another in numerous ways. IT service delivery usually entails managing customer information, and therefore, service quality and data protection have to go together.
Advantages of combining ISO 20000 and ISO 27001:
Consolidated documentation:
- You can leverage common policies such as training records, access logs, and audit reports.
Simplified audits:
- Certification bodies usually provide combined audits for both standards.
Improved market credibility:
- Having both certifications increases your attractiveness to enterprise customers and government contracts.
If you’re targeting international deals or wish to differentiate your business in a competitive tech industry, adopting both can provide a strong advantage.
How Much Do These Certifications Cost & How Long Do They Take?
The cost and time will depend on your company size, the complexity of your operations, and how much groundwork you’ve already done.
Aspect | ISO 20000 (IT Service Management) | ISO 27001 (Information Security Management) |
|---|---|---|
Implementation Time | Typically 3 to 5 months | Typically 4 to 6 months |
Maintenance Effort | Moderate requirements | Higher maintenance due to periodic risk assessments |
Annual Audits | Required to maintain certification | Required to maintain certification |
Cost & Timeline Factors | Depends on company size, complexity, and existing groundwork | Depends on company size, complexity, and existing groundwork |

Decision Guide: ISO 20000 or ISO 27001?
If you’re still not sure, ask yourself these brief questions:
- Are we offering IT support, hosting, or managed services to customers?
→ Yes → ISO 20000 - Do we process or store sensitive customer or employee information?
→ Yes → ISO 27001 - Are we going for contracts with multinationals, banks, or telecoms?
→ Both ISO 20000 & ISO 27001 can be necessary - Do we wish to differentiate ourselves from the competition in tech arena?
→ Dual certification could be considered

FAQ
Does ISO 20000 include security?
Not directly. While ISO 20000 promotes secure service delivery, it doesn’t dive deep into data confidentiality, encryption, or risk mitigation. That’s where ISO 27001 comes in.
Is it mandatory to get both certifications?
No. But if your operations involve both service delivery and data handling (as most tech companies do), implementing both can strengthen your systems and reputation.
Which one is easier to implement?
ISO 20000 tends to be quicker and less complex if your IT processes are already mature. ISO 27001 is more planning-intensive since it follows a risk-based methodology.
