ISO 27001 Certification: What It Is and When to Obtain It

ISO 27001 is not just any certification. For many companies, it is a true sales accelerator.

Imagine this scenario. You are about to close a deal with a major client, but at the last minute, a setback: the client is concerned about the security of their data. How reassuring would it be to immediately demonstrate that they have nothing to worry about?

If you are reading this article, you have probably found yourself in a situation like this and considered ISO 27001 certification as a solution. Let’s take a closer look at what it involves.

What Is ISO/IEC 27001 Certification?

ISO/IEC 27001 is an international standard developed through the joint work of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

ISO 27001 specifically certifies the ability to implement an information security management system (ISMS) based on:

• Risk analysis
• Procedural rules
• Monitoring
• Continuous improvement

The main characteristic of ISO 27001 is that it is globally recognized and therefore used as a benchmark to assess how reliable a company is.

The certification applies to the company as a whole, not to an individual or a product. This highlights that adopting such a system does not mean “building an invulnerable product,” but rather using a well-established and verifiable procedure.

In simple terms, this certification attests to a company’s ability to manage all sensitive data it handles through standardized procedures, including:

• Customer, partner, and employee data
• Access credentials
• Financial information
• Intellectual property

Why Obtain ISO 27001 Certification?

Achieving ISO 27001 requires a significant investment of time and money. So what are the advantages that motivate many founders to pursue it?

For many companies, especially in the digital and B2B sectors, the most obvious reason to obtain certification is competitive advantage. Having a third-party body certify optimal security management helps build trust more easily with clients, partners, and investors.

But it is not only about trust, which could otherwise be compensated for with strong sales skills. ISO 27001 also opens the door to commercial opportunities with large enterprises and public administrations, which may choose to work only with certified suppliers.

Beyond what the certification offers on paper, there are also concrete benefits for the company’s security. Truly applying the standard means changing the way risk is managed. It requires mapping vulnerabilities, introducing new control systems, and knowing in advance the best way to respond to potential data breaches or losses.

In practice, following this standard means being prepared for threats and, in the event of incidents, being able to intervene promptly and limit damage, including financial damage.

Moreover, following defined protocols helps organize processes, responsibilities, and documentation, areas that are often lacking, especially in SMEs where security management is frequently informal.

What is learned through certification creates a company-wide culture of security, which extends to other procedural aspects, such as documenting roles and responsibilities. As a result, it also positively impacts compliance with other applicable regulations, such as GDPR.

When Does It Make Sense to Obtain ISO 27001?

Despite the many advantages associated with ISO 27001, it is not suitable for everyone. Not because it is impossible to obtain, but because the costs are not always balanced by the benefits.

If you are wondering whether your company should pursue this certification, the following paragraphs provide an overview of situations in which certification can bring real value, as well as those in which it may not be convenient or may be premature.

Who Should Consider Certification?

The main parameters to evaluate when deciding whether to apply for ISO 27001 are two: the company’s level of maturity and its exposure to risk.

Companies that handle customers’ digital data or manage large amounts of personal data, especially sensitive data such as financial or health information, are strong candidates for ISO 27001 certification. This category includes:

• Software houses, SaaS companies, cloud providers, and IT suppliers
• Companies operating in sales, fintech, healthcare, and HR
• Organizations subject to strict sector regulations related to security, such as GDPR or NIS

But should all companies in these categories obtain ISO 27001? It depends. What is certain is that companies operating in these sectors should adopt internal procedures aimed at achieving certification, even in the absence of a formal requirement.

The clearest indicator that official ISO 27001 certification is needed often comes from client requests. When new clients repeatedly ask to complete security questionnaires, request information about business continuity plans, or seek details about backups and data centers, it is likely time to pursue certification.

When Does It Not Make Sense to Obtain Certification?

There are companies, especially startups, for which obtaining certification is not necessary, typically because they fall into these situations:

• They have few clients
• They do not handle sensitive data nor operate in highly regulated sectors
• They do not yet have structured security management processes

In such cases, the first step is often to build compliant internal processes and, only later, if necessary, pursue certification.

ISO 27001 is not a one-time commitment but a journey to be lived every day. Beyond the initial costs of certification, which include:

• Payment of the certification body and consultants
• Time investment from involved roles such as management and IT

It is also important to consider maintenance costs for renewing it year after year, including surveillance audits that can cost thousands of euros.

For small and medium-sized businesses, managing such a structured system can be very complex, with a cost-benefit ratio that may be unbalanced. Moreover, certification sometimes becomes mere formal compliance, without continuous governance integrated into daily operations. In practice, it turns into bureaucracy with no real impact.

Mabiloft: ISO 27001 as a Way of Working

At Mabiloft, we chose to adopt ISO 27001 processes even before obtaining formal certification. This means:

• Adopting risk management logic
• Coordinating technical and organizational controls
• Implementing continuous improvement practices

Although we are not yet certified, we work as if we were, and this has given us an advantage during audits for our clients. In particular, we supported Certiblok throughout its certification journey, during which auditors confirmed that many of the technical and organizational processes already in place were aligned with ISO 27001 requirements.

If you are considering certification and are still convinced after reading this article, choosing a partner who already lives these processes makes a difference because:

• We have first-hand experience with complex projects. We went through the entire certification cycle with Certiblok, from risk analysis to technical implementation, through certification and surveillance audits. We know what to expect and can anticipate common issues, shortening the required timeline.
• Our process is already structured. We have templates for policies, procedures, registers, and controls that have already been used in certification contexts and comply with the standard. The work we have done only needs to be adapted to the specific context. This allows us to avoid unnecessary bureaucracy and focus on what matters.
• We take an integrated business and technical approach. Coming from the DevOps and development world, we view ISO 27001 as a process architecture. We work on security without compromising delivery speed, finding the right balance between security and time to market.

What We Learned from ISO 27001 Certification

Gaining hands-on experience with ISO 27001 certification was not only beneficial for the client, but also provided us with valuable insights. We took away three important lessons.

The first is that ISO 27001 is not just a piece of paper, but a real shift in mindset. It is a management system that evolves over time and continuously improves, beyond the certificate itself.

The second lesson concerns scope. ISO 27001 is not only technical, but above all organizational. Firewalls, backups, and hardening mean little without clearly defined roles and responsibilities, established procedures, and continuous training.

Working with Certiblok, we discovered that the elements that truly make a difference are often those that are underestimated, such as defining who approves new production releases, knowing how to manage a potential incident, and being able to communicate effectively with clients in case of issues.

Finally, the last lesson we learned from this experience is that well-designed processes reduce stress. When procedures are predefined, sensible, and recognized by everyone, the team works more calmly, without last-minute solutions to prevent catastrophe.

This is where ISO 27001 becomes not just an investment in compliance, but an investment in the company’s health.

At Mabiloft, we choose to adopt this way of working every day because we believe in the security and quality of the products we develop. Following a regulatory standard allows us to build solid digital services.

If you are considering certifying your company, we can help you understand not only the path to obtaining ISO 27001 certification, but also how to leverage it in your daily work to gain tangible benefits. Contact us with no obligation and let’s talk about it together.
