A non-compete agreement restricts where you can work after leaving an employer; a non-disclosure agreement restricts what information you can share. That is the whole difference, and it drives everything else. A non-compete limits your actions in the job market. An NDA limits your speech about specific protected information. When you compare a non-compete vs. an NDA, you are comparing a restraint on your career against a restraint on what you can say, and the two carry very different legal weight.
You can be bound by one, both, or neither. In many employment contracts, you sign both in the same document without noticing they do different work.
What a Non-Compete Restricts
A non-compete bars you from working for a competitor or starting a competing business for a set period after you leave. The company’s argument is that it trained you, introduced you to its clients, and shared its playbook, and that letting you take all of that straight to a rival would undercut the investment.
A typical non-compete sets three boundaries:
- A time limit, usually between six months and two years.
- A geographic area, such as a metro region.
- A type of work, like selling the same category of product.
The narrower the restrictions, the more likely a court will enforce them. A clause barring you from your entire industry, anywhere in the country, for five years is the kind that gets thrown out.
What an NDA Restricts
An NDA, sometimes called a confidentiality agreement, prevents you from sharing specific proprietary information you learned during a business relationship. It does not limit where you work or what job you take. Its only focus is keeping certain data secret.
The heart of any NDA is its definition of “confidential information.” That definition usually covers trade secrets like formulas and proprietary algorithms, financial data such as revenue figures and pricing models, business relationships including customer lists and supplier contacts, and strategic plans like product roadmaps and expansion plans.
NDAs can be one-sided or mutual. In employment, they are almost always one-sided: you agree not to disclose the company’s information. In a negotiation or joint venture, both parties often share sensitive data, so a mutual NDA protects everyone.
The confidentiality obligation for ordinary business information usually lasts between two and five years. For trade secrets, the obligation can run indefinitely, because a trade secret only qualifies as one for as long as it stays secret. Federal law reinforces that: under the Defend Trade Secrets Act, a trade secret is any business, financial, scientific, or technical information that derives economic value from being kept secret, as long as the owner takes reasonable steps to protect it.
The Core Distinction: Actions vs. Information
Here is the clearest way to see it. You can fully comply with an NDA while working for a direct competitor. As long as you do not use or reveal the protected information from your old job, the NDA is satisfied. A non-compete, by contrast, would block that move entirely, regardless of whether you planned to share any secrets at all.
The two agreements address different fears. A non-compete protects against the competitive threat of your presence at a rival. An NDA protects against the specific harm of your old employer’s secrets getting out. A company worried about both will often use both clauses in a single contract.
Which One Is Actually Enforceable
Enforceability is where the two agreements diverge most sharply.
Non-Competes Depend Entirely on Your State
In April 2024, the Federal Trade Commission finalized a rule that would have banned most non-compete agreements nationwide. Under that rule, all new non-competes would have been prohibited, and existing non-competes for everyone except “senior executives” earning at least $151,164 per year in a policy-making role would have become unenforceable.1Federal Trade Commission. Noncompete Rule Employers would have had to notify affected workers.2Federal Trade Commission. FTC Announces Rule Banning Noncompetes
The rule never took effect. A federal district court in Texas vacated it nationwide, finding the FTC lacked authority to issue it. The FTC initially appealed, then in September 2025 dismissed those appeals and agreed to the vacatur.3Federal Trade Commission. Federal Trade Commission Files to Accede to Vacatur of Non-Compete Clause Rule There is no federal ban. State law controls, and it varies dramatically.
Four states ban non-competes in the employment context outright. California’s statute voids any contract that restrains someone from engaging in a lawful profession, trade, or business, and courts read that prohibition broadly to cover any non-compete clause in employment, no matter how narrowly written.4California Legislative Information. California Code BPC 16600 Minnesota, North Dakota, and Oklahoma have similar bans. Even in those states, non-competes can still be valid when someone sells a business and agrees not to open a competing one down the street.
More than 30 other states restrict non-competes short of a ban, through income thresholds, industry rules, or a general reasonableness test. In the states that apply a reasonableness standard, courts generally look at whether the company is protecting a legitimate interest like trade secrets or customer relationships, whether the duration is reasonable (one to two years is the typical ceiling), whether the geographic scope is reasonable, and whether you got something of value for signing. Some courts will narrow or rewrite an overbroad clause rather than void it. Others will void the whole thing. The same language can produce different results depending on where you signed.
NDAs Are Enforceable Almost Everywhere
NDAs face far less legal hostility. Courts generally enforce them if the definition of confidential information is clear and specific, the information is actually treated as confidential, and the duration is reasonable. An NDA that vaguely covers “all information learned during employment” is harder to enforce than one that lists categories. An NDA that tries to lock up general skills and industry knowledge will not hold up. And if the “confidential” pricing data was posted on the company’s public website, the clause covering it is effectively meaningless.
For ordinary business information, two to five years is common and rarely challenged. For trade secrets, courts allow indefinite protection because the obligation tracks the secret itself: once the information becomes public through legitimate means, the obligation ends on its own.
What an NDA Cannot Stop You From Doing
Even a valid NDA has limits. Several federal rules protect your ability to report wrongdoing, and companies that try to override them face enforcement action.
The SEC’s Rule 21F-17(a) prohibits any person from taking action to impede someone from reporting a potential securities law violation to the SEC, including enforcing or threatening to enforce a confidentiality agreement that would chill such reporting. Even an NDA that technically allows government reporting but requires you to notify the company first can violate the rule. The SEC has brought dozens of enforcement actions on this basis, including actions against major financial institutions and public companies as recently as early 2025.5Securities and Exchange Commission. Whistleblower Protections
Under the Defend Trade Secrets Act, you cannot be held criminally or civilly liable for disclosing a trade secret to a government official or an attorney solely to report or investigate a suspected violation of law, or in a filing made under seal. Employers are required to include a notice of this immunity in any agreement that governs the use of trade secrets or confidential information. An employer that skips the notice loses the right to recover enhanced damages or attorney’s fees in a later misappropriation suit.6Office of the Law Revision Counsel. 18 U.S. Code 1833 – Exceptions to Prohibitions
The National Labor Relations Board has also held that overly broad confidentiality and non-disparagement clauses in severance agreements can violate workers’ rights under the National Labor Relations Act, if they would reasonably tend to discourage employees from discussing wages, workplace conditions, or cooperating with the NLRB.
What Breach Looks Like for Each
The consequences overlap in places and diverge in others.
Breaking a Non-Compete
When a former employee violates a non-compete, the employer’s first move is almost always to seek an injunction, a court order forcing the employee to stop working for the competitor. To get one, the employer must show it is likely to win and that it will suffer irreparable harm without the order. Beyond the injunction, the employer can seek money damages for lost business tied to the breach.
The employer may also sue the new company. If the hiring company knew about the non-compete and hired the person anyway, the former employer can bring a tortious interference claim, which can carry compensatory and, in egregious cases, punitive damages.
Breaking an NDA
Breaching an NDA exposes you to a lawsuit for money damages measured by the losses the disclosure caused: the diminished value of a trade secret, lost profits, or increased costs the company incurred because the information got out. Many NDAs let the winning party recover attorney’s fees, which raises the financial stakes. Some include liquidated damages clauses setting a predetermined penalty, though courts will only enforce those if the amount is a reasonable estimate of actual harm rather than an arbitrary punishment.
For trade secret misappropriation specifically, the Defend Trade Secrets Act creates a separate federal cause of action. A court can issue injunctions, award actual damages or a reasonable royalty, and, if the misappropriation was willful and malicious, impose exemplary damages up to double the compensatory award. The statute of limitations is three years from when the misappropriation was discovered or should have been discovered.7Office of the Law Revision Counsel. 18 USC 1836
When You See Each One
Non-competes appear most often in employment agreements for people with access to sensitive competitive information: salespeople with deep client relationships, executives who know the strategic direction, and engineers working on proprietary technology. They also show up in business sale agreements, where the seller promises not to open a competing operation nearby. Technology, financial services, and healthcare have historically been the heaviest users.
NDAs have a much wider footprint. New employees sign them during onboarding. Contractors and freelancers sign them before receiving project details. Companies negotiating a merger or investment exchange NDAs before opening their books. Joint ventures and licensing discussions routinely begin with a mutual NDA. Because NDAs are less legally contentious and enforceable almost everywhere, they are far more common than non-competes.
A related clause, the non-solicitation agreement, often sits alongside both. It prevents you from recruiting your former employer’s clients or employees after you leave, without blocking you from working in the same industry. Courts enforce these more readily than full non-competes, and companies sometimes use one as a fallback when a non-compete might not hold up.
Why Many Contracts Contain Both
Many employment contracts bundle a non-compete, an NDA, and a non-solicitation clause into a single agreement. Each protects against a different threat. The NDA prevents you from sharing trade secrets with anyone. The non-solicitation clause prevents you from pulling away clients and colleagues. The non-compete prevents you from joining a rival at all for a limited period.
Take a senior sales director leaving a software company. Her NDA means she cannot share the proprietary pricing algorithms or unpublished product roadmap with anyone, anywhere. Her non-solicitation clause means she cannot contact her former clients to bring their business to her new employer. If she signed a non-compete in a state that enforces them, she may be barred from joining a competing software company at all for a year or two. Each clause fills a gap the others leave open.
If you are reviewing a contract and trying to figure out what you are actually agreeing to, read the clauses separately. Ask what each one restricts, how long it lasts, and whether your state will enforce it. The NDA will almost certainly stick. The non-compete is the one worth scrutinizing closely before you sign.
