In 2023, 43% of cyberattacks in Portugal targeted SMEs. Most didn't detect the intrusion for more than 200 days. This checklist fixes 80% of the most common vulnerabilities.
Access and password management
Most successful attacks start with compromised credentials.
- Enable 2FA on all critical services
- Use an enterprise password manager
- Immediately revoke access for former employees
- Implement password policy: minimum 16 characters
Backup and data recovery
Ransomware remains the #1 threat for SMEs. A correct backup is the only truly effective defense.
- 3-2-1 rule: 3 copies, 2 different media, 1 offsite
- Test backup restore at least once per quarter
- Keep at least one air-gapped copy
- Encrypt all backups at rest and in transit
An accounting firm in Lisbon lost 8 years of client data due to lack of isolated backup. Estimated cost: €340,000.
Team training and awareness
91% of attacks start with phishing. One hour of quarterly training reduces risk by more than 70%.
- Internal phishing simulations
- Social engineering recognition training
- Incident reporting protocol
Endpoint and network security
A compromised device on a flat network can compromise the entire organization in minutes.
- EDR installed on all devices
- Network segmentation: isolate IoT devices
- Mandatory VPN for remote access
Updates and vulnerability management
60% of intrusions exploit known vulnerabilities with patches available for more than 6 months.
