# Resilience, encryption, and compliance

This is the durability, encryption, and compliance data.

The reason is in [Resilience and security.](/docs-en/productos/object-storage/concepts/resilience-and-security.md)

### Durability

| Aspect             | Detail                                                              |
| ------------------ | ------------------------------------------------------------------- |
| Triple replication | Each object is stored on three disks across three different servers |
| Another location   | At least one copy is kept in a different data center                |
| Design             | Designed for very high data durability                              |

### Encryption and security

| Layer      | Protection                                        |
| ---------- | ------------------------------------------------- |
| In transit | Encrypted access via HTTPS                        |
| At rest    | Encrypted objects in storage                      |
| Perimeter  | Firewall, IDS/IPS, and anti-DDoS protection       |
| Isolation  | Each customer is logically isolated from the rest |
| Access     | S3 credentials that you control and rotate        |

### Compliance

| Framework | What it certifies                  | Scope          |
| --------- | ---------------------------------- | -------------- |
| ISO 27001 | Information security management    | International  |
| ENS       | National Security Scheme           | Spain          |
| HDS       | Health Data Host, health data      | France         |
| GDPR      | General Data Protection Regulation | European Union |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.plenit.com/docs-en/productos/object-storage/details/encryption-and-compliance.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
