# Security guide
### Data and network security
* All traffic to and from the Superblocks is encrypted using TLS 1.2, 1.3
* All data on the Superblocks platform is encrypted at rest using AES-256 encryption
* Superblocks servers are hosted in AWS across US and EU regions on SOC 2 and ISO 27001 certified infrastructure
* Superblocks resources (Applications, APIs, Workflows, Integrations, Audit Logs) are stored in encrypted and network-protected databases with limited internal access
### IP Addresses
The following IP addresses must be added to an allowlist in order for Superblocks to connect to your configured integrations.
| NAT hostname | Current DNS | Last Recorded IPs |
| ---------------------- | -------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| nat.superblocks.com | [A Records](https://dnsjson.com/nat.superblocks.com/A.json) | `107.22.228.244`
`3.93.101.124`
`34.209.17.50`
`34.227.169.51`
`35.155.119.178`
`35.171.116.214`
`35.86.18.137`
`44.232.244.93`
`54.148.33.216` |
| nat.eu.superblocks.com | [A Records](https://dnsjson.com/nat.eu.superblocks.com/A.json) | `13.50.50.66`
`13.50.81.30`
`13.51.231.18`
`52.17.136.219`
`54.220.65.107`
`99.81.159.1` |
While we do our best to never change these addresses, the best way to keep an updated allowlist is to use the current A records for the NAT hostname shown above, utilizing tools such as dig:
```bash theme={null}
dig +short nat.superblocks.com | sort
```
or by using an API like dnsjson.com:
```bash theme={null}
curl -s https://dnsjson.com/nat.superblocks.com/A.json | jq '.results.records|sort'
```
