Let's Encrypt features and specs

  • Free of Charge
    Let's Encrypt provides SSL/TLS certificates at no cost, making it an economical choice for individuals and businesses.
  • Automated Certificate Issuance and Renewal
    The process of obtaining and renewing certificates can be automated using the ACME protocol, reducing manual intervention and administrative overhead.
  • Ease of Use
    Let's Encrypt simplifies the process of enabling HTTPS for websites, even for users with limited technical expertise.
  • Security
    Let's Encrypt certificates provide strong encryption, improving the security of data transmitted between clients and servers.
  • Widely Recognized
    Certificates issued by Let's Encrypt are trusted by all major web browsers and operating systems.
  • Promotes Secure Web Practices
    By making SSL/TLS certificates freely available, Let's Encrypt encourages more websites to adopt HTTPS, contributing to a more secure internet.

Possible disadvantages of Let's Encrypt

  • 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.

Azure DDoS Protection features and specs

    Azure DDoS Protection provides detailed protection against multiple types of DDoS attacks, including volumetric, protocol, and application layer attacks, ensuring broad defense coverage.
  • Integration with Azure Services
    This service is seamlessly integrated with other Azure offerings, allowing easy setup and cohesive functionality within the Azure ecosystem.

Possible disadvantages of Azure DDoS Protection

  • Complexity
    While deeply integrated with Azure, setting up and managing DDoS protection may require a specific level of expertise and understanding of Azure’s infrastructure.
  • Limited to Azure
    Azure DDoS Protection is confined to Azure-hosted services, limiting its usefulness for applications or data hosted on other platforms or in hybrid environments.
  • Cost Implications
    Depending on usage and scale, the cost of Azure DDoS Protection can become significant, especially for small businesses with limited budgets.
  • False Positives
    Like many security measures, there is potential for false positives, where legitimate traffic might be mistaken for malicious activity, potentially impacting user accessibility.
