# Security

> Understand Fyno compliance guardrails and data privacy features, including reversible data masking, payload lifecycle governance, dual-control approval queues, HMAC endpoint signatures, and custom private S3/CloudFront media storage.

Security is considered one of Fyno's biggest selling points since we deal with the transmission of a lot of sensitive information and Personal Identifiable Information.

Therefore while implementing the **Security** features, a lot of consideration was put in, keeping **Compliance** as well as client data discretion in mind.

Fyno has 5 **Security** features that can be enabled for your account:

1. [Data Masking](./security/data-masking)
2. [Data Payload Storage](./security/data-payload-storage)
3. [Secure Allowlist Endpoints](./security/secure-allowlist-endpoint)
4. [Secure Media Storage](./security/secure-media-storage)
5. [Secrets](./security/secrets)
6. [OAuth Configuration](./security/oauth-configuration)

> **Note**
>
> Only users with 'Owner' or 'Super Admin' role can enable these security settings. Also these features are NOT AVAILABLE for Free Plan.

Before you enable any of these features, it is important to understand what each one does, to ensure your use case is being covered and you are achieving the security data protection.

> > **Note**

> > These security features, when enabled, applies only to "Live" version data.
