Cyber-Security in Accounting & POS Systems: What Every Business Should Know
27.11.2025
1 minute read
In today’s digital world, your accounting and POS systems hold the keys to your business. They store financial data, customer information and transaction history, which makes them prime targets for cyber-threats. For Maltese businesses, this means one breach could lead to downtime, data loss or regulatory headaches.
What are the main risks?
- Malware / ransomware – which can lock up your books or steal payment data.
- Phishing / credential theft – attackers gaining access through staff logins.
- Weak passwords or shared logins – common in retail or hospitality settings.
- Unpatched or outdated software – a known entry point for attackers.
How to protect your systems
- Choose robust software with built-in security. For example, Sage 200 Evolution supports advanced user roles and auditing.
- For retail/restaurant operations, Lightspeed Restaurant delivers cloud updates and centralised control, ensuring you’re better protected from vulnerabilities.
- Use strong, unique passwords + two-factor authentication for system users.
- Segment your networks: POS systems should be isolated from guest WiFi or insecure networks.
- Carry out regular backups: take automated daily backups, store off-site or in the cloud and test restores.
Your staff also matters
Your staff may be the weakest link. Make sure all users:
- Understand how phishing works.
- Never share passwords or use common default ones.
- Know how to handle unknown USBs/devices.
- Follow the correct data-handling procedures.
Ultimately, cyber-security isn’t just about IT, it’s about protecting your business, your reputation, and your customers. By using well-chosen systems like Sage 200 Evolution for your accounting and Lightspeed Restaurant for POS, following best practices and being proactive, you stand a much better chance of staying safe.
