When you bring someone into your business — whether as an employee, contractor, partner, or investor — two agreements come up more than almost any other: the NDA and the non-compete. Both are designed to protect your business. But they protect against very different risks, operate under different legal standards, and have very different enforceability profiles.
Choosing the wrong one, or using one when you need both, leaves gaps in your legal protection that can be expensive to close after the fact.
This guide breaks down exactly what each agreement does, when to use each, and how they compare across the dimensions that matter most. For NDA-specific drafting advice, see 7 common NDA mistakes to avoid.
What Is an NDA?
A non-disclosure agreement (NDA) is a contract that prohibits one or both parties from sharing confidential information with unauthorized third parties. It defines what counts as confidential, how long the obligation lasts, and what remedies are available if the obligation is breached.
NDAs are used across virtually every industry and business context:
- Hiring: Protecting proprietary processes, client lists, and internal systems
- Partnerships: Sharing financial data, strategic plans, or product roadmaps during due diligence
- Contractors: Granting access to internal tools, codebases, or customer data
- Investor conversations: Disclosing revenue figures, growth metrics, or intellectual property
The core function of an NDA is information control. It does not restrict what someone can do — only what they can say or share.
What Is a Non-Compete Agreement?
A non-compete agreement restricts an individual from working for a direct competitor, starting a competing business, or soliciting the company's clients for a defined period after the business relationship ends. It typically specifies:
- Duration: How long the restriction lasts (usually 6–24 months)
- Geographic scope: Where the restriction applies (a city, state, country, or worldwide for remote roles)
- Activity scope: What specific competitive activities are prohibited
Non-competes are most commonly used in:
- Employment contracts for senior or specialized employees with access to trade secrets
- Business sale agreements where the seller agrees not to immediately compete with the buyer
- Partnership dissolution where one partner agrees to stay out of the same market
The core function of a non-compete is competitive protection. It restricts what someone can do — regardless of whether confidential information is involved.
NDA vs Non-Compete: Side-by-Side Comparison
| Dimension | NDA | Non-Compete | |-----------|-----|-------------| | What it protects | Confidential information | Market position and competitive advantage | | What it restricts | Sharing or using proprietary information | Working for competitors or starting a competing business | | Typical duration | 2–5 years (or indefinite for trade secrets) | 6–24 months | | Geographic scope | Usually none (information has no geography) | Defined area (city, state, country) | | Enforceability | Generally enforceable in all U.S. states | Varies widely — banned in some states, restricted in many | | Common parties | Employees, contractors, partners, investors | Employees, business sellers, departing partners | | Consideration required | Varies — employment itself may suffice | Often requires additional consideration beyond at-will employment | | FTC status (U.S.) | Not affected by proposed FTC rules | Subject to evolving federal scrutiny and potential bans | | Remedies for breach | Injunction + damages | Injunction + damages (harder to prove damage amount) |
When to Use an NDA
Use an NDA when confidential information will be exchanged and you need legal recourse if it leaks:
- Before sharing business plans with a potential partner or investor
- When hiring employees or contractors who will access trade secrets, code, or client data
- During merger or acquisition due diligence when both parties share sensitive financials
- In vendor relationships where the vendor will handle customer data or proprietary systems
An NDA is appropriate even when a non-compete would be excessive or unenforceable. The bar for enforcing an NDA is much lower — courts generally respect the right to protect genuinely confidential information.
When to Use a Non-Compete
Use a non-compete when the real risk is not information leakage but direct competition:
- Senior employees who could take institutional knowledge to a rival
- Selling a business — the buyer needs assurance the seller will not immediately re-enter the market
- Key salespeople with deep client relationships that are personally portable
- Specialized technical roles where the employee's expertise is a meaningful competitive asset
Before drafting a non-compete, always verify enforceability in the relevant jurisdiction. A non-compete that violates state law is not just unenforceable — it can create legal liability for the employer.
When You Need Both
In many business relationships, information protection and competitive protection are both necessary:
- A departing CTO knows your technical architecture (NDA) and could launch a competing product (non-compete)
- A departing sales director has your client list (NDA) and existing client relationships (non-compete)
- A departing co-founder has full operational knowledge (NDA) and the ability to replicate the business (non-compete)
When both risks are present, the standard approach is to include both clauses in a single agreement or to execute both agreements simultaneously. The NDA protects information indefinitely (or for a longer period), while the non-compete restricts competitive activity for a shorter, defined window.
Enforceability Considerations
NDAs
NDAs are enforceable in all 50 U.S. states when they are:
- Specific about what information is confidential
- Reasonable in duration
- Supported by adequate consideration
- Not used to conceal illegal activity
Non-Competes
Non-compete enforceability is a patchwork:
- Banned outright: California, Oklahoma, North Dakota, Minnesota, and (for most workers) Colorado
- Restricted: Many states limit non-competes to employees above a certain salary threshold, require garden leave payments, or cap duration
- Generally enforced: States like Florida, Texas, and Georgia enforce non-competes when scope and duration are reasonable
Always draft non-competes with jurisdiction-specific requirements in mind. A one-size-fits-all non-compete is the most common reason these agreements fail in court.
Protect Your Business with the Right Agreement
Whether you need an NDA, a non-compete, or both depends on what you are protecting and who you are protecting it from.
For most business relationships, an NDA is the baseline — it is widely enforceable, straightforward to draft, and protects your most sensitive information. A non-compete adds a second layer of protection when the risk extends beyond information to direct competitive threat.
