Security Posture Analysis
Comprehensive Security Assessment
The security maturity of Standard Notes is high, leveraging end-to-end and zero-knowledge encryption to protect user data. The website enforces HTTPS and uses Cloudflare DNS, though DNSSEC is not enabled, which is a minor gap. The codebase is open source and independently audited, enhancing transparency and trust. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a security.txt file and incident response contact emails limits formal vulnerability disclosure channels. The lack of a cookie consent mechanism despite tracking scripts is a minor compliance gap. Overall, the security culture appears strong with room for formalizing some policies.
