Threat assessment
Survival Period
Survival provisions define how long confidentiality and other NDA obligations continue after the agreement ends. Perpetual or overly long survival periods are a common red flag.
What it is
The survival period is the duration confidentiality (and sometimes non-solicit or non-compete) obligations remain in force after the NDA terminates or expires. It is distinct from the term of the business relationship itself.
Why it matters
Standard commercial NDAs often use 2–5 years of post-termination confidentiality. Perpetual confidentiality — or survival tied to trade-secret status without limits — can lock you into obligations indefinitely for information that may no longer be sensitive.
Red flags to watch for
- Perpetual confidentiality without mutual benefit
- Survival exceeding 5 years for routine business discussions
- No clear termination date for the agreement itself
- Survival of overly broad definitions of confidential information
Market norms
- Mutual NDAs between peers: 2–3 years survival is common
- Investor or M&A contexts: longer survival may be justified for true trade secrets
- Freelancer/client NDAs: push for survival aligned with project end + 1–2 years
NDAShield perspective
Termination and survival language is a core section in every analysis. Compare survival periods across multiple NDAs using a consistent Burn Score methodology before you commit to long-running confidentiality obligations.
