What is an ISMS (and why you’ll be hearing a lot about it in the coming months)
If you’ve heard of ISO 27001, then it’s time to meet the real star behind the standard: the Information Security Management System as it’s known among friends ISMS.
In a world where any company can become a target (yes, even the small ones), protecting data isn’t a luxury — it’s a survival strategy.
If you're curious about how an ISMS works — even without certification — keep reading. We're giving you a checklist. This post was made for you.
What is an ISMS?
ISMS means Information Security Management System, in other words, a system for managing information security.
It is not a tool, nor software. It is a structured set of policies, processes and practices that help your company protect critical information — from customer data to internal strategic plans.
The goal? To ensure that information security is managed in a structured, continuous, and risk-aligned way..
Why is the ISMS linked to ISO 27001?
The standard ISO 27001 s the international standard that defines the requirements for an effective ISMS.
It doesn’t “create” an ISMS — it organises and validates what you implement. ISO certification proves that your organisation:
- Assesses risks based on evidence
- Protects data in a systematic way
- Has real policies, training, and control measures in place
But most importantly: it helps make security part of your company’s culture - not just a concern for the IT department.
Do I need to be certified to have an ISMS?
No!
In fact, many companies already follow practices similar to an ISMS — without even realising it. Certification is optional, but implementing the principles of an ISMS is essential for any organisation that handles sensitive data.
Even without the seal, an ISMS helps you to:
- Identify where you're vulnerable
- Prepare responses to incidents
- Create clear policies for your team
- Demonstrate accountability to partners and clients
How do I know if I already have an ISMS?
Imagine a startup that handles customer data and operates remotely.
Even without certification, it can have a functional ISMS in place with:
✅ Password policy and MFA
✅ Information classification (public, internal, sensitive)
✅ Automated and encrypted backups
✅ Incident logging and lessons learned
✅ Basic training in digital security
The result? Fewer risks, greater trust, and smarter decision-making.
Checklist to see if you're on the right track
- Do you have a written information security policy?
- Do your employees receive training on security (the whole team — not just one person)?
- Do you know where your most sensitive data is stored?
- Are there clear procedures in place for dealing with incidents?
- Is there a security culture (or is everything improvised)?
If you answered “no” to two or more, it’s time to start building your ISMS.
