NDA or trade secret protection: what is the difference?
An NDA is a contract binding one named person not to disclose. Trade secret status is a legal quality the information itself holds, but only while you take reasonable steps to keep it secret. NDAs are one of those steps, so they are not alternatives, they are layers of the same protection.
A signed promise from a specific person or company, enforceable as a contract between you and them.
A protected legal status for information that has commercial value because it is secret and is actively kept secret.
How do they compare, point by point?
| CRITERION | AN NDA | TRADE SECRET STATUS |
|---|---|---|
| What it is | A contract | A legal status of the information |
| Binds | Only the person who signed | Anyone who misappropriates it, including strangers |
| Cost to establish | Free to a few hundred euro | The ongoing cost of your security practices |
| Registration | None | None, and registering would destroy it |
| Duration | The term you write, often two to five years | Forever, until the secret gets out |
| Survives disclosure | You can sue for breach, but the secret is gone | No, the status ends the moment it is public |
| Remedy | Damages for breach of contract | Injunction and damages for misappropriation |
| Needed before a pitch | Yes, if they will sign one | Yes, always |
Why is an NDA not enough on its own?
An NDA only reaches the person who signed it. If your idea leaks through an unsigned contractor, an old laptop or a public deck, the NDA gives you nothing against whoever picks it up.
It is also only worth what enforcement is worth. Suing on an NDA costs real money and requires you to prove both the disclosure and the loss.
What makes something a trade secret?
Three things in every major jurisdiction: it has commercial value because it is not generally known, it is not readily discoverable, and you take reasonable steps to keep it secret.
The third one is where almost every claim fails. Reasonable steps mean access controls, marked documents, signed NDAs, exit procedures when people leave and a record of who saw what and when.
The upside is that trade secret status has no expiry and no filing fee. The recipe stays protected for as long as it stays secret.
What does a record of disclosure add?
Both protections turn on evidence. If you cannot show what you disclosed, to whom and on what date, you cannot show breach and you cannot show reasonable steps.
A dated, numbered record of the disclosure, held outside your own inbox, is the cheapest evidence you will ever buy.
Which one should you choose?
CHOOSE AN NDA WHEN
- You are about to show something to a named party
- You want a contractual remedy you can point at
- The other side is a company with assets worth suing
CHOOSE TRADE SECRET STATUS WHEN
- The information has long term value and no expiry date suits you
- You cannot get everyone who touches it to sign
- You want a remedy against people you never contracted with
Common questions
+Should I make an investor sign an NDA?
Most will refuse, and pushing it reads as inexperience. Protect the implementation detail rather than the concept, disclose in stages, and keep a dated record of what you showed and when.
+Does an NDA protect an idea nobody has built yet?
It protects the disclosure of it, not the idea in the abstract. Ideas are not owned. What is protectable is the specific expression, the data, the method and the sequence of steps.
+How long should an NDA last?
Long enough to cover the commercial life of the information. Two to five years is normal for a project. For anything you would call a trade secret, ask for the obligation to survive indefinitely for that category.
