Theft of confidential information, including client lists, trade secrets, or intellectual property, can be just as damaging as financial theft.
These breaches can undermine competitive advantage, client trust, and business reputation. We see these cases frequently, and early action is critical.
Catherine Ballantyne provides some useful tips as to what you should do in this situation.
1. Secure the Data
Immediately identify what information has been compromised and restrict further access. Cybersecurity experts may be needed to contain the breach.
2. Seek an Injunction
Urgent injunctions can prevent the misuse of confidential information while your claim for damages proceeds.
The Court will be quick to hear these types of cases, understanding that there is real urgency to prevent the use or dissemination of the confidential information.
3. Consider Additional Court Orders
Depending on the circumstances, you may also seek:
- Search Orders to recover documents or data
- Freezing Orders to prevent the perpetrator from dealing with assets
4. Protect Your Intellectual Property
If intellectual property is involved, litigation may be necessary to prevent competitors from benefiting from stolen information.
5. Rebuild Client Confidence
If clients are affected, proactive communication and strengthened protections can help restore trust.
Lessons
Once your data has been stolen by an employee, you need to act quickly to secure the data and prevent its use. This will usually require a Court application.
