Non-Disclosure Agreements (NDAs): What They Are and Why They Matter

 Non-Disclosure Agreements (NDAs) are foundational contracts that let businesses share sensitive information with employees, contractors, partners, investors, and prospective buyers without losing control of that information. Used correctly, NDAs deter leaks, preserve trade secret rights, and create clear legal remedies if confidentiality is breached.

What is an NDA?
An NDA (confidentiality agreement) is a legally binding contract that creates a confidential relationship between parties and restricts the use and disclosure of defined “Confidential Information.” NDAs can be unilateral (one-way) or mutual (two-way) depending on whether one or both sides disclose sensitive information.

Types of NDAs

• Unilateral NDA: Only one party discloses information (e.g., employer to employee, startup to contractor).
• Mutual NDA (MNDA): Both parties share sensitive information (e.g., M&A evaluations, partnership talks).
• Employee/Contractor NDA + IP assignment: Often combined with invention assignment and non-solicit.
• Investor NDA: Less common with institutional VCs pre‑term‑sheet; more common with strategic partners or nontraditional investors.
• Research/Clinical NDAs: Specialized definitions, data handling rules, and compliance add‑ons (HIPAA, GLP, etc.).
• Patent/Pre‑filing NDAs: Used to avoid public disclosures that could jeopardize patent rights.

Key clauses you must include

• Parties and purpose: Identify the legal entities and the limited purpose for which information can be used.
• Definition of Confidential Information: Define what is protected (written, oral, electronic, samples) and mark/confirming‑memo requirements; include derivative data and analyses.
• Exclusions: Information already known, independently developed, publicly available, or rightfully obtained without breach.
• Use and disclosure restrictions: Use only for the stated purpose; disclose only to personnel/advisors with a need‑to‑know bound by similar obligations.
• Standard of care: At least reasonable care, often no less than what the recipient uses to protect its own similar information.
• Security requirements: Baseline controls (access control, encryption at rest/in transit, logging), breach notification timelines, retention/deletion.
• Return or destruction: Return or securely destroy upon request or at term end; allow one archival copy if justified for compliance.
• Term and survival: Contract term (often 1–3 years) and survival of confidentiality (commonly 2–5 years; trade secrets often survive indefinitely while they remain trade secrets).
• IP rights and no license: No implied license granted; ownership of discloser IP and improvements clarified; feedback license (narrow, royalty‑free) if applicable.
• Non‑solicitation (optional): Narrow, time‑limited non‑solicit of employees/customers where permitted by law.
• Compelled disclosure: Procedure for subpoenas/court orders—prompt notice, cooperation to seek protective orders, disclose only what’s required.
• Remedies: Acknowledge irreparable harm and availability of injunctive relief in addition to damages; limit liability carve‑outs for confidentiality breaches.
• Governing law and venue: Choose a predictable jurisdiction; consider arbitration vs courts and fee‑shifting for willful breaches.
• Entire agreement and assignment: Integration clause; restrictions on assignment (change‑of‑control carve‑out for buyers).

When to use an NDA

• Hiring and contracting: Before sharing roadmaps, code, client lists, pricing, or manufacturing processes.
• Partnering and vendor selection: Sharing APIs, security architecture, SOPs, or bid packages.
• M&A and investment: Sharing financials, product plans, and diligence materials (note: many VCs resist pre‑term‑sheet NDAs).
• Product testing and PR: Embargoed media reviews, beta programs with access to unreleased features.
• Patent strategy: Pre‑filing discussions to avoid public disclosure risks.

Enforceability and limitations

• Reasonableness: Courts scrutinize overly broad definitions, long survival periods for non‑trade‑secret information, and use restrictions that exceed the stated purpose.
• Trade secrets: NDA discipline supports trade secret status; careless marking/controls can undermine protection.
• Public domain and whistleblower carve‑outs: NDAs cannot block lawful reporting to regulators or courts; include whistleblower immunity notices where applicable.
• Jurisdictional issues: Employee‑related restrictions are more heavily scrutinized in some states; ensure state‑specific compliance.

Practical playbook

• Before sharing: Classify data, mark it, and share only what’s necessary; use secure channels and access controls.
• Templates and versioning: Maintain approved NDA templates (unilateral and mutual) with playbooked fallbacks for negotiations.
• Data handling rules: Attach a short security schedule for sensitive categories (PII/PHI, source code, crypto keys).
• Clean teams: For competitive situations, limit access to need‑to‑know personnel and advisors under separate NDAs.
• Docketing: Track signature versions, expiration, survival dates, and return/destruction confirmations.
• Incident response: Pre‑write steps for suspected breaches—preserve evidence, suspend access, send notice, and seek injunctive relief if needed.

Common mistakes to avoid

• Vague definitions or purpose clauses that invite arguments later.
• Failing to include advisors/affiliates and subcontractors within the confidentiality chain.
• Not specifying data security standards or breach notice timelines.
• Over‑promising (e.g., perpetual confidentiality for ordinary business data instead of trade secrets).
• Relying on NDAs without operational controls—weak access, poor logging, and no off‑boarding checklist.

Simple clause starters (to tailor with counsel)

• Confidential information: “Confidential Information means any non‑public information disclosed by Discloser—whether oral, visual, or in tangible form—identified as confidential or that a reasonable person would understand to be confidential given its nature and the circumstances of disclosure, including derivatives and notes thereof.”
• Use limits: “Recipient shall use Confidential Information solely for the Purpose and shall not disclose it to any third party except to its Representatives who need to know for the Purpose and are bound by written obligations at least as protective as this Agreement.”
• Security and breach: “Recipient shall implement administrative, physical, and technical safeguards no less protective than those used for its own similar information, including access controls and encryption in transit and at rest, and shall notify Discloser without undue delay of any confirmed breach.”

FAQs

• Do I need an NDA with every vendor?
  Use NDAs when sharing non‑public information beyond what’s reasonably necessary to procure a commodity service; otherwise use scoped contractual confidentiality.
• Are emails and verbal disclosures covered?
  Yes, if the NDA covers oral disclosures (often requiring timely written confirmation) and electronic communications.
• How long should confidentiality last?
  Commonly 2–5 years for ordinary business information; trade secrets should remain protected as long as they qualify as trade secrets.
• Can NDAs stop whistleblowing or reporting crimes?
  No. NDAs should expressly allow disclosures required by law and protected whistleblower activity.
• Do VCs sign NDAs?
  Many institutional VCs won’t pre‑term‑sheet; share only non‑secret, high‑level materials until a term sheet or use a targeted, mutual NDA with strategic investors.
