Every business runs on data—sales orders, customer details, stock levels, and financial reports. And all of this important information is stored inside your ERP system. That’s why ERP data security is no longer optional. It is the heart of business safety. A single security mistake can lead to data loss, financial damage, system downtime, customer mistrust, and even legal trouble.

But the good news is: with the right ERP practices and strong security tools, businesses can stay fully protected. This guide explains everything in simple, easy-to-understand language—no technical terms, no complexity.

What Is ERP Data Security?

ERP data security means protecting all the information stored in your ERP system from:

  • Loss
  • Misuse
  • Unauthorized access
  • Cyberattacks
  • Accidental mistakes

Your ERP system holds the most sensitive data of your business. So securing it is as important as securing your money.

ERP data security means keeping all the information inside your ERP system safe and protected. This includes preventing data loss, misuse, unauthorized access, cyberattacks, and even simple mistakes made by users. Your ERP stores some of the most important details of your business—like customer records, sales data, financial information, and inventory levels. Keeping this data secure is as important as protecting your company’s money, because any security issue or mistake can directly affect your business, your customers, and your reputation.

Why ERP Data Security Matters

Businesses today face more digital risks than ever before. Cyberattacks are rising, more companies are moving to the cloud, teams are working remotely, and ERP systems are connected to many external apps and devices. All these changes make your ERP system a bigger target and increase the chances of data problems.

A strong ERP security plan helps your business stay safe and stable. It allows you to:

  • Prevent unauthorized access
  • Reduce overall business risks
  • Build customer and stakeholder trust
  • Protect financial and operational data
  • Keep your daily operations running without interruption

Top ERP Data Security Challenges

Below are the most common and high-risk security issues businesses face with ERP systems—and why they happen.

1. Weak User Access Control

Many companies give excessive permissions to employees.

For example, a salesperson may have access to finance or inventory data they don’t need.

This increases the chances of misuse, accidental deletion, or unauthorized data sharing.

Why it happens:

  • No proper role-based access control (RBAC)
  • Lack of access monitoring
  • No approval workflow for permission changes

Risk: Unauthorized access and exposure of sensitive business data.

2. Outdated ERP Software

Managing old or unsupported ERP versions creates serious security gaps.

Hackers can easily target systems that do not have the latest patches or updates.

Why it happens:

  • Delayed updates or upgrades
  • Lack of IT support or maintenance team
  • Using old on-premise ERP systems without security patches

Risk: High vulnerability to cyberattacks, malware, and unauthorized access.

3. Lack of Data Backup

Many businesses still do not follow a proper backup strategy.

If the system fails or gets attacked, critical data may be permanently lost.

Why it happens:

  • No automated backup system
  • Not storing backups on the cloud
  • Reliance on manual backup methods

Risk: Severe data loss, long downtime, and business disruption.

4. Cybersecurity Threats and Hacking

ERP systems attract hackers because they store highly valuable information such as:

  • Customer details
  • Financial records
  • Purchase and sales data
  • Supplier information

Why it happens:

  • Weak firewalls
  • Poor password security
  • No encryption of data

Risk: Data theft, ransomware attacks, financial loss, and reputational damage.

5. Poor Integration Security

ERP systems connect with many external applications like CRM, HRMS, eCommerce, POS, and payroll. If any connected system is weak, the hackers can use it as a backdoor to enter the ERP.

Why it happens:

  • Too many third-party apps
  • No API security checks

Risk: Cyberattacks through insecure integrated applications.

6. Human Errors

Employees often unintentionally compromise ERP security by:

  • Clicking on phishing emails
  • Using simple or repeated passwords
  • Accessing unsafe websites or files
  • Sharing login credentials

Risk: Accidental leaks, unauthorized access, and security breaches caused by simple mistakes.

Major ERP Data Security Risks to Watch

  • Ransomware attacks – attackers lock your data and demand money
  • Unauthorized access – people accessing data they should not see
  • Data leakage – sensitive information getting exposed
  • Internal misuse – employees using data in the wrong way
  • System downtime – operations stopping due to technical issues
  • Financial fraud – manipulation of financial data
  • Loss of customer trust – customers losing confidence in your business

These risks impact manufacturing, trading, services, retail, distribution, and any business that depends on an ERP system.

How to Protect Your ERP System – Best Practical Solutions

Here are easy and effective steps every business can follow to keep their ERP system safe.

1. Use Role-Based Access (Give access only to the right people)

Make sure each employee can see only the information they need for their job.

For example:

  • Sales team → only Sales data
  • Finance team → only Finance data
  • Warehouse team → only Inventory screens

This simple step reduces mistakes, prevents misuse, and protects sensitive information.

2. Keep Your ERP Updated Regularly

Updates come with important security fixes.

If your ERP is not updated, it becomes easy for attackers to enter.

Cloud ERPs like Microsoft Dynamics 365 Business Central get automatic updates, which keeps your system safe with no extra effort.

3. Enable Multi-Factor Authentication (MFA)

MFA adds a second layer of protection when logging in.

Even if someone gets the password, they still cannot access the system without the second verification step.

It greatly reduces the risk of unauthorized access.

4. Encrypt Your Data

Encryption makes your data unreadable to anyone who tries to steal or misuse it.

Even if the information is taken, it stays safe and protected.

5. Use Strong Password Policies

Encourage your team to follow simple password rules:

  • Minimum Use 8–12 characters
  • Include combination letters, numbers, and symbols
  • Change passwords regularly

Strong passwords are one of the easiest ways to improve security.

6. Set Automatic Data Backups

Daily backups help you recover quickly if something goes wrong—like a system crash, malware attack, or data corruption.

Cloud ERPs such as Business Central already include secure, automated backup options.

7. Secure All Integrations

Your ERP may be connected to CRM, payroll, eCommerce, POS, or other apps.

If one of these apps is weak, the attacker can enter your ERP through it.

Use trusted apps, secure APIs, and review integration security regularly.

8. Train Employees Regularly

Many security problems happen because of simple human mistakes.

Training helps employees identify and avoid:

  • Phishing emails
  • Malware
  • Suspicious links
  • Unsafe downloads

A trained team is one of the strongest protections for your ERP.

  • Set up a secure ERP system
