Promotes Secure Web Practices

Possible disadvantages

Short Duration of Certificates
Let's Encrypt certificates are valid for only 90 days, requiring more frequent renewals compared to traditional certificate authorities.
Limited Support Options
Let's Encrypt relies on community support and documentation, and does not offer dedicated customer support for troubleshooting and assistance.
No Extended Validation (EV) Certificates
Let's Encrypt does not issue Extended Validation (EV) certificates, which provide additional verification and a higher level of trust for business websites.
Potential for Misuse
Since certificates are issued for free and with minimal validation, there is a risk that cybercriminals might use them for phishing or other malicious activities.
No Wildcard Certificates for Multi-Level Subdomains
While Let's Encrypt supports wildcard certificates for single-level subdomains, it doesn't support them for nested subdomains (e.g., *.sub.example.com).
Reliance on Third-Party Tools for Automation
Users may need to rely on third-party tools or scripts for automation, which could introduce additional complexity or security risks.
