Quick Answer: An NDA (ื”ืกื›ื ืกื•ื“ื™ื•ืช, heskem sodiyut) in Israel is governed primarily by the Commercial Torts Law 5759-1999 and the Contracts (General Part) Law 5733-1973. Courts enforce well-drafted B2B NDAs readily, but employee NDAs face strict scrutiny โ€” any clause that prevents a worker from using general professional skills will be struck down. The key to an enforceable Israeli NDA is precise definition of exactly what information is confidential, a reasonable duration (typically one to three years), and, for employee agreements, clear separation between protectable trade secrets and the employee's own accumulated expertise.

Israel has over 6,500 active tech companies and more venture capital per capita than almost anywhere else. That ecosystem runs on confidential information. Every time a founder pitches an investor, a company explores an acquisition, or an employer brings on a senior engineer, sensitive material changes hands. The NDA is the legal instrument that controls what happens to that information after the meeting ends.

Foreign companies entering Israel, diaspora entrepreneurs, and multinationals hiring local talent all run into specific surprises with Israeli NDA law. Courts apply a rights-based framework that actively protects employees' freedom to work, and the definition of a protectable "trade secret" is narrower than most foreign businesses expect. Finding these gaps after a key engineer walks out to join a competitor is the expensive way to learn this. Addressing them upfront is not.

Israel does not have a single statute called the "NDA Law." Instead, confidentiality obligations in Israel are built from several interlocking layers:

  • Commercial Torts Law 5759-1999 (ื—ื•ืง ืขื•ื•ืœื•ืช ืžืกื—ืจื™ื•ืช): This is the primary statute protecting trade secrets in Israel. Section 6 defines a "trade secret" as business information whose confidential nature gives the holder a commercial advantage over competitors who lack it. Section 7 establishes civil liability for anyone who misappropriates a trade secret, whether or not they signed an NDA. The law covers disclosure, use, and even the threat of imminent misuse.
  • Contracts (General Part) Law 5733-1973 (ื—ื•ืง ื”ื—ื•ื–ื™ื (ื—ืœืง ื›ืœืœื™)): The NDA itself is a contract, so standard principles of Israeli contract law apply โ€” offer, acceptance, consideration, good faith performance under Section 39, and the rules on voiding unreasonable clauses.
  • Standard Form Contracts Law 5742-1982 (ื—ื•ืง ื—ื•ื–ื™ื ืื—ื™ื“ื™ื): Employment NDAs issued on the employer's standard-form template may be subject to challenge under this law if they contain oppressive terms. The Courts Supervisor can void clauses that unfairly prejudice employees.
  • Patents Law 5727-1967 and Copyright Law 5768-2007: These provide parallel protection for specific categories of IP and can reinforce NDA obligations, though they operate independently of confidentiality agreements.

Israeli law does not require a signed NDA to protect a trade secret. Section 7 of the Commercial Torts Law imposes liability on anyone who discloses or uses trade secrets even without a signed agreement, provided they knew or should have known the information was confidential. The NDA adds value by defining exactly what is covered, setting an explicit duration, and creating contractual remedies โ€” agreed penalties and injunctions โ€” that the statute alone does not provide.

In Practice: Section 9 of the Commercial Torts Law 5759-1999 expressly gives District Courts jurisdiction to grant interim injunctions in trade secret cases โ€” including ex parte (without notice) injunctions where there is evidence of imminent disclosure. In urgent cases Israeli courts typically schedule an ex parte hearing within 24โ€“72 hours of filing. If your former employee or partner is about to disclose your proprietary algorithm, customer database, or manufacturing process, you do not need to wait for a full trial. An urgent application to the Tel Aviv District Court (which handles most technology and commercial matters) with your NDA, evidence of the threatened breach, and an affidavit from your CEO can freeze the disclosure before it happens.

2. What counts as a protectable trade secret in Israel

The single most common drafting error in Israeli NDAs is defining "confidential information" so broadly that courts refuse to enforce the agreement. Israeli law is specific about what qualifies as a trade secret worth protecting, and what does not.

What is protectable

Under Section 6 of the Commercial Torts Law, information qualifies for protection as a trade secret if it meets three criteria:

  • It is not in the public domain and is not readily accessible to those in the relevant industry by standard means.
  • Its confidential character gives the holder a competitive advantage.
  • The holder has taken reasonable steps to maintain its secrecy.

Typical examples that Israeli courts have upheld as protectable trade secrets include:

  • Proprietary source code, algorithms, and technical architecture documents.
  • Customer lists that contain pricing history, purchasing patterns, or special terms โ€” as opposed to publicly known client names.
  • Manufacturing processes, formulations, or production methods that are not disclosed in the company's patent filings.
  • Business plans, financial projections, and market research prepared at company expense that are not disclosed to investors or the public.
  • Details of ongoing merger, acquisition, or fundraising negotiations.

What is not protectable

Israeli courts will not protect general industry knowledge, publicly available information, or skills an employee developed during their career. This line matters especially in technology companies, where the boundary between proprietary know-how and general engineering expertise is often contested.

The courts have consistently held that an employee's mental capacity and general professional skills โ€” even if significantly developed or sharpened during their employment โ€” belong to the employee, not the employer. A software developer who becomes expert in a particular programming framework during their job cannot be prevented from using that expertise after leaving. An NDA clause attempting to achieve this outcome will be struck down as contrary to public policy.

In Practice: Section 13 of the Commercial Torts Law 5759-1999 gives courts discretion to exempt a person from trade secret liability where the relevant information became part of their "general professional skills" during employment. Israeli courts apply this section actively. In one frequently cited District Court ruling, a senior developer who had been a central architect of a SaaS product's database layer was found to have legitimately retained his understanding of the system's general design principles โ€” only the specific proprietary implementation details remained protected. Draft your NDA's definition of "confidential information" around specific identified categories of information, not sweeping phrases like "any and all information acquired during employment." The latter will almost certainly be reduced by a court.

3. Employee NDAs: the rules that catch foreign companies off guard

Employee NDAs in Israel work differently than most foreign companies expect. Courts apply a more demanding standard here than they do to commercial agreements between two companies, and the gap catches employers off guard regularly.

The freedom-to-work principle

Israeli courts treat freedom of occupation (ื—ื•ืคืฉ ื”ืขื™ืกื•ืง) as a fundamental right, protected both under general case law and under Section 3 of the Basic Law: Freedom of Occupation. (The Basic Law technically applies to government restrictions, but courts cite the underlying principle in private employment disputes routinely.) Any contractual clause that substantially prevents a departing employee from earning a living in their field will face serious judicial scrutiny.

This does not mean employee NDAs are unenforceable. It means they must be narrowly drafted. Courts balance:

  • The employer's legitimate interest in protecting genuinely confidential information and real trade secrets.
  • The employee's right to work in their chosen profession and use skills they have developed.
  • The public interest in labour mobility, competitive markets, and the free flow of talent, particularly relevant in Israel's concentrated tech sector.

Consideration for employee NDAs

An NDA signed at the start of employment, as part of standard onboarding, is generally valid in Israel. The job itself is sufficient consideration. An NDA presented to an existing employee partway through their tenure is a different matter: without something additional offered to the employee (a pay rise, a promotion, a bonus, or an express statement that continued employment is contingent on signing), the agreement may be challenged for lack of consideration. Several Israeli Labor Court decisions have voided after-the-fact NDAs on exactly this ground.

In Practice: The Regional Labor Court (Tel Aviv branch handles the highest volume) is the venue for employment-related NDA disputes. Claims for breach of an employment NDA that seek compensation and injunction are heard in the Labor Court, not the District Court โ€” a distinction that matters because Labor Court judges are specialists and the court has developed its own well-defined jurisprudence on the limits of post-employment confidentiality. The Labor Court can issue interim injunctions on a same-day or next-day basis in urgent cases. Filing fees in the Labor Court for a claim with a value above NIS 100,000 are approximately NIS 1,640, with ongoing legal costs for a contested case typically ranging from NIS 30,000 to NIS 120,000 per side for proceedings through a first-instance judgment.

Non-compete clauses versus NDAs

Foreign businesses frequently include non-compete clauses (ืื™ืกื•ืจ ืชื—ืจื•ืช) in the same document as the NDA. These are two distinct obligations with very different enforceability in Israel. While NDAs protecting genuine trade secrets are generally enforceable, blanket non-compete clauses prohibiting a former employee from working for any competitor are extremely difficult to enforce in Israeli courts. Courts require that a non-compete clause be supported by specific additional consideration (a lump sum payment, a higher salary during the restriction period), be limited to a specific geographic scope and duration, and be genuinely necessary to protect identifiable trade secrets rather than just limiting competition. The NDA and non-compete should be drafted as separate obligations with separate consideration where possible.

4. B2B and startup NDAs: the commercial context

When two commercial entities enter an NDA โ€” a foreign tech company and an Israeli development partner, or a VC fund and a startup seeking investment โ€” Israeli courts apply a different standard than they do in employment. Both parties are presumed to be sophisticated, to have had access to legal counsel, and to have freely agreed to the terms. Courts generally enforce clearly worded commercial NDAs, including penalty clauses and longer durations, without the policy override that applies to employees.

Mutual versus unilateral NDAs

In an investment or partnership context, the standard NDA is mutual (ื”ืกื›ื ืกื•ื“ื™ื•ืช ื”ื“ื“ื™): both parties agree not to disclose each other's confidential information. This is the appropriate form when both parties will share sensitive material โ€” the startup's technology and financials, the investor's due diligence methodology and fund strategy. A unilateral NDA makes sense when only one party is disclosing, for example, a potential acquirer conducting initial diligence on the target company before signing a letter of intent.

For Israeli startup founders approaching international investors, the mutual NDA is the norm. Most sophisticated Israeli VCs and foreign funds will have a standard form they prefer, but any NDA that clearly identifies the parties, defines what is confidential, sets a reasonable duration, and includes a governing law and jurisdiction clause will generally be treated as enforceable.

In Practice: Israeli courts have consistently held that a two to three year duration for a B2B NDA related to a technology transaction is reasonable, while a ten-year or indefinite duration for specific categories of technical information (source code, undisclosed patent-pending inventions) can also be upheld if genuinely justified by the sensitivity of the material. Where B2B NDAs most often fail in court is not on duration but on scope: a clause stating "all information disclosed in any form" without further specification tends to be treated as overbroad and severed by courts, leaving the agreement enforceable only for information that would independently qualify as a trade secret under the Commercial Torts Law. Add specific categories ("financial projections labelled CONFIDENTIAL", "source code repositories shared via [platform]", "customer list in Schedule A") to make the NDA litigation-ready.

5. Key clauses every Israeli NDA must include

These are the provisions that determine whether an Israeli NDA holds up in court or gets severed into irrelevance:

Definition of confidential information

Specify categories precisely. Name specific document types, systems, databases, or processes. Avoid catch-all language as the sole definition. Where appropriate, include a schedule of specific items. The more specific the definition, the easier the NDA is to enforce and the clearer the obligations on both parties.

Carve-outs

Every enforceable Israeli NDA must exclude from the definition of "confidential information" information that: (a) was already in the public domain before disclosure; (b) enters the public domain without breach of the agreement; (c) was already known to the receiving party; or (d) was received independently from a third party without restriction. Courts expect these standard carve-outs. An NDA without them suggests the drafter was attempting to create an unreasonably broad restriction and will raise judicial suspicion about the entire agreement.

Purpose limitation

State explicitly that confidential information may only be used for a defined permitted purpose โ€” for example, "evaluating a potential acquisition of the Company" or "performing the services under the Master Services Agreement dated [date]." A purpose limitation prevents the receiving party from mining disclosed information for other projects or competitive intelligence.

Duration

For commercial B2B NDAs: two to three years is standard; three to five years is acceptable for highly sensitive technical information; indefinite duration for specific categories (trade secrets that retain value indefinitely, such as proprietary formulas) with a clear sunset clause tied to the information entering the public domain. For employment NDAs: one to two years post-employment is the upper limit Israeli courts consistently accept without challenge.

Agreed penalty clause (ืคื™ืฆื•ื™ ืžื•ืกื›ื)

Israeli contract law (Section 15 of the Contracts Remedies Law 5731-1970) allows parties to agree in advance on a fixed compensation amount for breach. This is valuable in NDA cases because proving actual damages from a confidentiality breach is notoriously difficult. A per-breach amount of NIS 50,000โ€“500,000 is typical for commercial NDAs, calibrated to the sensitivity of the information and the transaction size. Courts can reduce a penalty that is "grossly disproportionate" to foreseeable harm, but a figure tied to the realistic value of the protected information will usually stand.

Governing law and jurisdiction

Specify Israeli law as governing law and name the competent court. For commercial disputes between companies, specify the Tel Aviv District Court. For international transactions where one party is based outside Israel, you may opt for arbitration rather than court proceedings; if so, include a valid arbitration clause under either the Arbitration Law 5728-1968 (domestic arbitration) or reference to the ICC or LCIA rules for international disputes. Note that opting for foreign-law arbitration does not prevent an Israeli court from granting urgent interim relief under Section 9 of the Commercial Torts Law while the arbitration is pending.

In Practice: Section 30 of the Contracts (General Part) Law 5733-1973 voids contractual provisions that are contrary to public policy. In practice, Israeli courts have used this section to strike down NDA clauses that function as disguised non-compete agreements, that restrict the use of publicly available regulatory filings, or that attempt to bind third parties who never signed the agreement. Review every NDA through this lens before finalising: if a clause, applied literally, would prevent a reasonable professional from doing their job in Israel, it will likely not survive a court challenge. The answer is always to narrow the scope, not to hope for judicial mercy.

6. When an NDA is breached: remedies and courts

If a party breaches your NDA in Israel, two parallel routes are available. They are not mutually exclusive.

Civil claim for damages

A civil claim for breach of NDA and misappropriation of trade secrets is heard in the District Court (for claims above NIS 2.5 million) or the Magistrate Court (for smaller claims). You can seek both the agreed contractual penalty and additional damages if you can prove losses exceeding the penalty amount. In technology cases, Israeli courts have awarded damages based on what the defendant saved or gained by using the secret, rather than requiring the plaintiff to prove their own losses. That is a more claimant-friendly approach than the default.

Emergency injunction

The most powerful remedy in an NDA case is a tzav mnia'a zmanit (temporary injunction) preventing the defendant from using or disclosing the information while litigation proceeds. You can apply for an ex parte injunction โ€” one granted without hearing from the other side first โ€” where disclosure is imminent and any delay would cause irreparable harm. Under Section 9 of the Commercial Torts Law 5759-1999, the standard for a trade secret injunction is satisfied where: (a) there is a prima facie case that a trade secret exists and was misappropriated; (b) the balance of convenience favours the applicant; and (c) damages alone would not be an adequate remedy because of the irreversible nature of disclosure.

Israeli courts have granted emergency injunctions within hours when evidence of imminent misappropriation was clear. A typical fact pattern: a departing employee found to have downloaded large volumes of proprietary files to a personal drive on their last day. The injunction can prohibit that employee from starting a new role, freeze specific devices, and require immediate return of all company materials.

In Practice: If you discover a breach or imminent breach of your NDA, act within the first 48 hours. Delay significantly weakens your position when applying for an emergency injunction โ€” courts ask why you waited and may infer that the situation was not truly urgent. The immediate steps: (1) preserve all digital evidence โ€” server logs, access records, email exports โ€” before the person can cover their tracks; (2) contact your attorney to draft the injunction application; (3) prepare an affidavit from a company officer with direct knowledge of the breach and its potential consequences; (4) file at the Tel Aviv District Court using the urgent applications track (typically assigned a hearing within 24 hours for genuine emergencies). Court filing fees for an emergency trade secret injunction application are approximately NIS 1,600โ€“4,000 depending on the relief sought. Attorney fees for preparing and arguing the application typically range from NIS 15,000 to NIS 50,000. Compare this to the potential cost of the trade secret reaching a competitor.

Criminal liability under the Commercial Torts Law

Section 11 of the Commercial Torts Law 5759-1999 creates a criminal offence for deliberate misappropriation of trade secrets, punishable by up to three years' imprisonment. While criminal prosecutions for trade secret theft are relatively rare in Israel, the existence of criminal liability is a meaningful deterrent and relevant when the breach involves a deliberate commercial espionage scenario rather than inadvertent disclosure. A criminal complaint filed with the Israel Police's Lahav 433 economic crimes unit runs parallel to, and does not prevent, civil proceedings.
