SSL & HTTPS
Every site is generated with an SSL Certificate and is served over HTTPS, meaning that your site data is encrypted.
According to Cloudflare, HTTPS is more trustworthy, secure, and authenticated.
Static & Serverless Sites
All The.com sites are static sites. Static sites are more secure because there is no chance of attackers intercepting and changing the data as it loads from server to server.
Even if The.com's Editor is down, your site will not be affected because sites are deployed statically through AWS.
Serverless sites also means less risk of downtime due to maintenance or security breaches since there are teams on the Cloud Service Providers dedicated to keeping your site from attacks.
