If you’re an entrepreneur, this fear is very real.
You spend years building your business, your clients, pricing strategy, marketing approach, internal processes, only to worry that an employee might walk out one day, take all that confidential information, and either start a similar business or join your competitor.
And to be clear, when we talk about confidential information, it’s not always high-tech inventions or cutting-edge technology.
Very often, it’s things like, customer lists and customer preferences, pricing structures and discount strategies, marketing plans and sales pipelines, internal business data and workflows.
These may not look like typical intellectual property at first glance, but in law, they can still be protected under confidentiality, especially in an employee and employer relationship.
This is exactly why relying on “trust” alone is risky.
From a business perspective, it’s far better to put clear, strategic safeguards in place early, not just to prevent problems while the employee is still around, but also to protect yourself after the employee leaves, when most disputes actually happen.
In the sections below, we’ll walk you through:
how the law looks at confidentiality in employment,
a real Malaysian court case showing how a business used a strong NDA to stop its ex-employee from exploiting its business secret, and
3 practical steps entrepreneurs can take to protect their business through a proper Confidentiality Clause or Non-Disclosure Agreement.
A Real Malaysian Case: When an Ex-Employee Takes a Company’s Confidential Information and Becomes a Direct Competitor
To see how confidentiality really works in the real world, let’s take a look at a Malaysian court case that sets a very good example for entrepreneurs.
In Inhome Group Sdn Bhd & Anor v Kuan Kok Han [2025] CLJU 1706, the employer did something fundamentally right that many businesses still overlook.
In this case, the employee, Kuan, was not just an ordinary staff member. He was Inhome’s Sales and Marketing Manager, and that matters a lot.
His role gave him access to customer enquiries and long-term customer relationships, pricing and marketing strategies, designs, drawings, and internal templates and business know-how that powered Inhome’s awning business.
In other words, he was deeply involved in the core commercial operations of the company.
Inhome trusted him enough to give him wide access to confidential business information, and even allow him to acquire 1% shareholding in the company.
After working with Inhome for more than seven years, Kuan resigned in December 2022.
Just weeks later, he incorporated Dream Home Structural Works Sdn Bhd, a company offering the same awning services, to the same market, and in direct competition with Inhome.
Starting a Competing Business Is Legal. So What Went Wrong?
Let’s be clear about one thing first.
Starting a competing business, by itself, is not a problem. An employee is generally free to leave, start something new, or even join a competitor.
That was not the issue here. The real problem was what Kuan did after he left Inhome.
After resigning, he continued using his Inhome email account, continued receiving customer enquiries meant for Inhome, secretly sourced drawings and templates from an existing Inhome employee, and used those materials to build and grow his new business.
As a result, Inhome sued Kuan for, breach of confidence, breach of duty of fidelity, copyright infringement, and unlawful interference with trade.
The key question before the Court was simple, but serious:
“Did Kuan merely take his experience with him, or did he take Inhome’s confidential information?”
What Did the Employer Rely On?
The Employment Contract and Non-Disclosure Agreement (NDA)
When bringing its claim for breach of confidence, Inhome did not rely on assumptions or verbal understandings. It relied on two key documents that Kuan had signed during his employment:
the Employment Contract, and
a Non-Disclosure Agreement (NDA).
These documents formed the legal foundation of Inhome’s case. They made it very clear that certain information belonged to the company, not to the employee.
What Was Stated in the NDA That Made the Difference?
This was not a vague or loosely drafted NDA. The NDA expressly stated that:
confidential information could only be used for Inhome’s business
the employee must not disclose or use the information for personal benefit or for any other business
the duty of confidentiality survived termination indefinitely
In plain English, this meant one thing. Even after resignation, Kuan was still legally bound not to use or exploit Inhome’s confidential information in his new venture.
That point turned out to be critical.
The Law on Breach of Confidence Explained (In Simple Terms)
So how does the court actually decide whether there is a breach of confidentiality? In Malaysia, the court applies a well-established three-part legal test.
The information must have the necessary quality of confidence
Meaning, the information must not be public knowledge.
It must be commercially sensitive, something that gives the business an advantage. This can include customer lists, pricing strategies, internal processes, designs, or business data.
If anyone can easily find it online, it is usually not confidential.
The information must be given in circumstances creating an obligation of confidence
This often arises naturally in an employee and employer relationship.
When an employee receives information because of their role, especially a senior role, the law assumes that the information is given in confidence, even if it is not stamped “confidential” on every document.
In this case, Kuan was a senior employee. He received access to the information only because he worked for Inhome.
There must be unauthorised use that causes harm
Finally, the employer must show that the information was used without permission, and that this caused harm or gave the employee an unfair advantage.
This does not always mean proving exact financial loss.
Even using confidential information to compete unfairly can be enough.
The High Court applied this exact test in this case and found that all three elements were satisfied.
Why Did the Employer Win the Case?
Short answer: because the employer was prepared.
Inhome had a strong confidentiality agreement in place, and it knew exactly what it was protecting.
The agreement clearly identified what counted as confidential information, instead of leaving things vague.
Evidence That Proved Unauthorised Use of Confidential Information
This case was not decided on theory alone. It was decided on evidence.
The Court was persuaded by proof showing that Kuan continued using the Inhome email account after resignation.
3 Practical Steps to Protect Your Business Through a Confidentiality Agreement
Based on the lessons from the Inhome case, here are three practical steps every entrepreneur should take.
Step One: Make Sure You Have a Proper Confidentiality Clause or a Non-Disclosure Agreement
This sounds basic, but you will be surprised how many businesses get this wrong.
Every employment contract should contain a clear confidentiality clause, or at the very least, there should be a separate Non-Disclosure Agreement (NDA) signed by the employee.
The Inhome case clearly shows why this matters.
Step Two: Identify and Classify What Is Truly Confidential
A common mistake entrepreneurs make is saying, “Everything in my business is confidential."
Legally and practically, that does not work.
You need to be clear about, what information is truly confidential.
Customer lists, pricing strategies, internal processes, designs, and business data are common examples of confidential information and intellectual property of your company, even if they are not registered.
When you clearly identify and classify confidential information, it becomes much easier to explain to employees what they can and cannot use, and much easier to convince a court later if a dispute arises.
Step Three: Limit Access on a Need-to-Know Basis and Set Clear Protocols
Confidentiality clauses alone are not enough if everyone in the company has access to everything.
From both a legal and business perspective, access to confidential information should be given on a need-to-know basis.
This means:
only giving access to information that an employee genuinely needs for their role,
restricting access when roles change, and
having clear internal protocols for handling confidential documents, emails, and data.
If you are not sure whether your current employment contracts or confidentiality agreements truly protect your business, this is a good time to review them.
