## What it covers

- **Secure design**: Security decided at the start: who sees which data, what gets logged, what happens when something fails.
- **Access control**: Sign-in, roles and permissions, and single sign-on with the identity provider you already use.
- **Hardening**: Servers, containers and cloud accounts set up with only what they need, and kept up to date.
- **Review**: A look at an existing application or infrastructure, with a written list of what to fix first.

## How we work

We apply the same practice we use on the products we build: Alearatio, IusRatio and Atlasposting.

We work with your team, on your systems, with only the access the job needs.

At the end you have it in writing: what we found, what we changed, what is left to do.
