Legacy ERP systems, like Dynamics GP and SL, aren’t just outdated, they’re a cybersecurity liability. While they may still handle critical business functions, their outdated architecture and lack of modern security features make them prime targets for increasingly sophisticated cyberattacks.

Quisitive has seen firsthand how organizations with unsupported ERP systems are leaving their most sensitive data exposed, and the consequences that have followed.

The Hidden Dangers of Legacy ERP

Legacy ERP systems often suffer from:

• End-of-life support: Without vendor patches or updates, vulnerabilities remain open indefinitely.
• Missing modern security controls: Many legacy systems lack multi-factor authentication (MFA), role-based access controls, or AI-driven threat detection.
• Complex, fragile infrastructure: Customizations and integrations over time increase risk and reduce maintainability.

Legacy ERP systems significantly increase security exposure, as they cannot support modern cybersecurity practices like automated patch management and advanced threat detection.

Real-World Consequences

The risks aren’t hypothetical; they’re happening every day. Deloitte’s Future of Cyber survey revealed that 66% of organizations said they had suffered anywhere from one to as many as ten cybersecurity incidents or breaches in just a 12-month period.^[1]

Legacy ERP systems are frequently at the heart of these incidents. Running on outdated architecture, missing modern protections, and lacking safeguards, they provide cybercriminals with an easy entry point.

When most organizations are already battling multiple cyber threats annually, clinging to unsupported ERP systems doesn’t just raise your risk, it practically guarantees it.

Why Cloud ERP Is the Safer, Smarter Choice

Migrating to a cloud ERP platform isn’t just a technical upgrade, it’s a risk mitigation strategy. Cloud ERP systems provide:

• Advanced encryption and access controls
• Automated patching and updates
• AI-powered threat detection
• Built-in disaster recovery and business continuity

Forrester’s Total Economic Impact™ study shows that organizations retiring legacy ERP systems in favor of cloud solutions achieve significant cost savings, faster innovation cycles, and improved security posture.^[2]

Waiting to modernize ERP may feel like a cost-saving choice, but it’s a false economy. The average data breach now costs $4.88 million, not including the unquantifiable damage to brand trust and customer relationships.

Every day your legacy ERP remains in use is another day of exposure.
