How does anonymization contribute to "cyber resilience" — protecting privacy even when a breach occurs?

Anonymization reduces the impact of a breach, not just its probability — stolen anonymized data can't be used to harm specific individuals.

The realistic premise: the question is not if a breach will happen, but when. Most controls aim to lower the probability of a breach. Anonymization is different — it lowers the impact:

• Stolen data can't harm individuals. Properly anonymized data can't be used to blackmail, intimidate, or discriminate against a specific person — the link back to identity is broken.
• Data retains its value. Even after a breach, the anonymized data is still useful for analytics and learning — the leak doesn't destroy its legitimate value.

That's why anonymization belongs to cyber resilience: it ensures that when defenses fail, the damage to people is contained.

Tip: Encryption protects data at rest until the key leaks; anonymization protects the people even after the data itself is fully exposed.
