Cybersecurity made clear: basics, risks and first steps
Practical, plain-language cyber awareness for Hungarian SMEs and suppliers — from the most common risks to the first, doable steps.
This page is Regcytech’s own plain-language explanatory material. It is not legal advice, not certification, and does not replace a professional security assessment. Our work supports readiness and documentation.
What is cybersecurity?
In short, cybersecurity means an organisation deliberately protects its data, systems and operations against digital threats — and prepares for the case when something does go wrong.
It is not only technology: it is just as much a question of people, processes and habits. Most incidents are not sophisticated “hacking” but a preventable mistake stemming from the lack of clear basics.
Why is it not only a large-enterprise problem?
Most attacks are not targeted but automated and mass-scale: they can reach anyone, regardless of size. Smaller companies are often easier targets because fewer protections are in place.
On top of that, SMEs are increasingly part of supply chains where larger partners expect demonstrable security practice. So cybersecurity is not only risk management but also a business entry ticket.
The most common attack types
- Phishing: deceptive messages aimed at obtaining data or access.
- Password theft: obtaining and using weak or reused passwords.
- Business email compromise (BEC): fraud disguised as a manager or partner, often pushing for a transfer.
- Ransomware: encrypting data and demanding a ransom.
- Supply chain risk: the attack reaches its target through a weaker partner.
- Poorly managed access: too many permissions, forgotten accounts, no review.
What does cyber hygiene mean?
Cyber hygiene is the handful of basic, regularly repeated habits that prevent most risks — like hand-washing prevents many illnesses. It is not flashy, but it is the most effective protection.
The key is consistency: strong, unique passwords, multi-factor authentication, updates, backups and aware users. Together these stop or limit the majority of attacks.
10 basic steps for SMEs
- 01Use strong, unique passwords and a password manager.
- 02Multi-factor authentication (MFA) on important accounts.
- 03Regular updates on devices and software.
- 04Regular, tested backups — with an offline or isolated copy.
- 05Review access: only those who need it should have rights.
- 06Raise staff awareness, especially recognising phishing.
- 07Anti-malware and basic device protection on every machine.
- 08Identify and consciously handle sensitive data.
- 09Basic security consideration of suppliers and providers.
- 10A simple, written incident-handling path for when something goes wrong.
How does it connect to NIS2 and ISO/IEC 27001?
These can connect, but do not guarantee compliance — actual applicability must be checked against an official source.
- NIS2: it expects risk-based operation, incident management and supplier security from in-scope organisations — basic cyber hygiene is its natural starting point.
- ISO/IEC 27001: system-level information security management, for which these same basics provide the practical background.
- Supplier questionnaires (e.g. CyberVadis-style): well-ordered practice and evidence make answering easier.
- All three together: basics built once are reusable for several expectations.
What is an incident-response plan?
An incident-response plan is a simple, pre-written path for when a security event occurs: who does what, who must be notified, how to limit the damage, and how to recover.
It does not have to be complex. The point is not to improvise at the moment of crisis — a prepared response is faster, with less damage, and demonstrably shows responsible operation.
How can Regcytech help?
We work in an advisory, readiness and documentation role:
- NIS2 readiness and a quick gap review
- cybersecurity advisory and setting up basic cyber hygiene
- a gap assessment and audit-preparation support
- putting together an incident-response plan and a policy starter pack
- organising evidence for supplier and CyberVadis-style questionnaires
- support for ISO/IEC 27001 readiness
What we do not provide
We work in an advisory, readiness role. The boundaries are clear:
- We do not operate a SOC or an MDR service.
- We do not perform penetration testing, certification or accredited audits.
- We do not provide a 24/7 emergency incident-response guarantee.
- We do not provide a legal or compliance guarantee.
