Companies have made significant progress in digitalisation, but cybersecurity challenges continue to grow. A small business now relies on email, cloud services, mobile devices, external providers, management tools, social networks and payment platforms. Each entry point can become a risk if there are no clear rules.
Cybersecurity is not only technical. It also affects GDPR compliance, business continuity and the trust of clients and employees. INCIBE explains in its business section that cyber threats may cause financial losses, reputational damage and sanctions.
In this article we will discuss...
1. Move from isolated tools to internal policies
Antivirus software and backups are useful, but they are not enough if every employee acts differently. The company needs simple rules for passwords, devices, email, downloads, cloud use, permissions and incident response.
INCIBE provides security policies for SMEs that can be used as a starting point.
2. Protect email and credentials
Email remains one of the main entry points for phishing, trojans and CEO fraud. Basic measures should include multi-factor authentication, unique passwords, staff training and out-of-band verification before payments or bank account changes.
3. Control providers and external access
Many incidents do not start inside the company, but through providers with access to systems, hosting, maintenance, software or personal data. Companies should review permissions, limit access, cancel old users and document data processing agreements where providers process personal data on their behalf.
4. Prepare for a security breach
The question is not only how to prevent incidents, but how to respond when they happen. The company should know who decides, what evidence must be preserved, how internal communication works, when the IT provider is contacted and when notification to the AEPD within 72 hours must be assessed.
Basic checklist for SMEs
- Inventory of devices, accounts, applications and critical providers.
- Multi-factor authentication for email, cloud, banking and admin panels.
- Tested and protected backups.
- Regular system and application updates.
- Permissions reviewed according to role and real need.
- Short and recurring staff awareness training.
- Written incident response procedure.
Conclusion
Business cybersecurity is not solved with one tool. It requires habits, controls, training and continuous review. For an SME, clear policies, secure credentials, controlled providers and an incident response plan are already a major improvement.
