NDA vs Non-Compete: What’s the Difference and When Do You Need Each?

The fundamental difference

A Non-Disclosure Agreement (NDA) says: "You can’t share what you learn." A Non-Compete Agreement says: "You can’t work for a competitor."

An NDA protects information — trade secrets, customer lists, pricing models, proprietary algorithms. The restricted party can still work anywhere they want; they just can’t take your secrets with them.

A non-compete restricts activity — where someone can work, what kind of business they can start, and for how long after leaving. It doesn’t matter whether they use your confidential information or not.

When you need an NDA

NDAs are appropriate in virtually every business relationship where non-public information is exchanged. Common scenarios include: hiring employees or contractors who will access proprietary systems, sharing business plans with potential investors, evaluating a potential acquisition or partnership, engaging consultants who will see internal data, and working with vendors who process your customer information.

A well-drafted NDA should include five standard exclusions (publicly available information, prior knowledge, independent development, third-party receipt, and compelled disclosure), a return/destruction clause, and a reasonable duration (typically 3 years, with trade secrets protected indefinitely).

When you need a non-compete

Non-competes are appropriate in a much narrower set of situations: senior executives with access to strategic plans, salespeople with deep client relationships, employees who develop core IP, and founders selling a business.

Critically, non-competes are increasingly restricted or banned. California has never enforced them. The FTC attempted a nationwide ban in 2024. Colorado, Minnesota, Oklahoma, and North Dakota have significant restrictions. Many states require additional consideration (usually garden leave pay) for enforcement.

The practical alternative: non-solicitation

Between NDAs and non-competes sits the non-solicitation agreement. It says: "You can work for a competitor, but you can’t recruit our employees or poach our customers."

Non-solicitation clauses are generally more enforceable because they’re narrower in scope. Courts view them favorably because they don’t prevent someone from earning a living.

For most businesses, an NDA paired with a non-solicitation clause provides better protection than a non-compete, with far fewer enforceability risks.

Red flags in both agreements

In NDAs: watch for overly broad definitions of confidential information, missing exclusions, no return/destruction requirement, and indefinite duration for non-trade-secret information.

In non-competes: watch for durations over 12 months, geographic scope broader than where you actually worked, no garden leave compensation, and restrictions that would prevent you from working in your entire field.
