Sign an NDA online — privately

Why privacy matters specifically for NDAs

A non-disclosure agreement often names the parties, the confidential subject matter, and the terms of a deal that has not been announced. Routing that document through a third-party server — even a reputable one — creates a copy outside your control. That is directly at odds with the purpose of the agreement itself.

Signing in the browser avoids that entirely. The NDA is opened, signed, and saved on your own device, so the only copies that exist are the ones you and the counterparty deliberately hold. When you return the signed file by email or secure file transfer, the document stays between the two parties and no one else.

What to check before you sign an NDA

Before signing, confirm the essentials:

• >The definition of "confidential information" is not broader than you expect — some NDAs sweep in information that is already public or independently developed.
• >The term — how long the obligation lasts after the relationship ends. A standard confidentiality period is three to five years; indefinite terms are unusual and worth questioning.
• >Whether it is mutual (both sides are bound) or one-way (only the receiving party is bound).
• >Any carve-outs for information you already knew, that becomes public through no fault of yours, or that you receive independently from a third party.
• >The permitted use — the agreement should state that confidential information can only be used for the specified purpose, not for any other purpose.
• >Breach remedies — most NDAs allow the disclosing party to seek injunctive relief without posting a bond, which is a significant provision to understand.

Mutual vs. unilateral NDAs

A unilateral NDA protects one party's information — typically a company asking a contractor, job candidate, or vendor to keep its materials confidential. A mutual NDA binds both parties equally and is common when two businesses are exploring a partnership or acquisition where each side will share sensitive details.

Before you sign, identify which type you have. A mutual NDA creates obligations on you as well as the other party, meaning information they share with you is protected too. If you receive a unilateral NDA but you will be sharing your own confidential information in the relationship, it is reasonable to ask for a mutual version.

Is an electronically signed NDA enforceable?

Yes. NDAs are standard commercial contracts, and electronic signatures are legally recognized under the US Electronic Signatures in Global and National Commerce (ESIGN) Act and the Uniform Electronic Transactions Act (UETA), which has been adopted by 49 states. The EU eIDAS regulation provides the equivalent framework across European Union member states.

Under these laws, a signature cannot be denied legal effect solely because it is electronic. For an electronically signed NDA to be enforceable, the basic requirements are that both parties intended to sign, both consented to transact electronically, the signature is associated with the document, and a copy can be retained. Signing a PDF and exchanging it by email satisfies those requirements in the typical commercial NDA context.

There are narrow categories of documents — such as wills, certain court filings, and documents requiring a notary — that are excluded from ESIGN and UETA. Standard commercial NDAs are not among them.

When a wet signature might still be required

Most commercial NDAs are fully enforceable with an electronic signature. However, a few situations call for extra care. If the NDA will be submitted to a court as part of a filing, confirm the court's requirements. If the counterparty's template explicitly states that it requires a handwritten signature, honor that request. Some regulated industries — particularly government contracting — may impose their own signature requirements on confidentiality agreements tied to classified or controlled information.

When in doubt, ask the other party before signing. The safest approach is always to confirm the counterparty's requirements rather than assume.

Record-keeping after signing

Once both parties have signed, keep the executed NDA somewhere you can find it. Store it alongside any correspondence that establishes the context — the email thread that led to signing, any attachments that define the scope of the engagement. If a dispute ever arises about whether information was covered by the NDA, that context is valuable.

Name your file clearly: something like "NDA_CompanyA_CompanyB_2026-01-15_signed.pdf" is far easier to locate than a generic filename. A simple folder per counterparty or per project keeps executed agreements organized as you accumulate them.

How DocSignHub handles your NDA

When you open a PDF in DocSignHub, the file is loaded directly into your browser using the browser's own PDF rendering. No part of the file is transmitted to DocSignHub's servers or any other server. You draw, type, or upload your signature, place it on the document, and download the result — all within the browser tab. There is no account, no subscription, and no storage of your documents on external infrastructure.

This architecture makes DocSignHub particularly appropriate for NDAs, where the whole point is that the information does not leave the parties involved.
