As Let’s Encrypt certificates are a popular choice for securing websites and services, it’s essential to understand how they work and what benefits they offer. Let’s Encrypt is a free, open-source certificate authority (CA) that provides domain-validated SSL/TLS certificates for web servers and applications. These certificates use public key infrastructure (PKI) technology to verify the identity of the website owner, ensuring that data transmitted between the browser and server remains private and secure. To obtain a Let’s Encrypt certificate, you need to follow these steps: 1. Verify your domain ownership by creating a specific file on your web server or setting up a TXT record in your DNS configuration. 2. Create a Certificate Signing Request (CSR) for your domain using software like OpenSSL or an online tool. 3. Submit the CSR and your domain verification to Let’s Encrypt. Let’s Encrypt certificates are issued in a matter of minutes, compared to traditional certificate authorities that can take several days to issue a certificate. This is because Let’s Encrypt uses automated processes and does not require manual review of application forms. In addition to its speed and efficiency, Let’s Encrypt also offers other benefits: * Free: Let’s Encrypt provides SSL/TLS certificates at no cost. * Automated: The process of obtaining and renewing certificates is automated, eliminating the need for manual intervention. * Open-source: The Let’s Encrypt project is open-source, which allows developers to review the code and contribute to its development. By using Let’s Encrypt certificates, you can ensure that your website or application remains secure and private, while also benefiting from a fast and efficient certificate management process.

Sophos Firewall 21 offers comprehensive support for Let’s Encrypt certificates across multiple aspects of the firewall configuration.

Let’s Encrypt is a non-profit, publicly trusted certificate authority, operated by the Internet Security Research Group (ISRG), issuing X.509 digital certificates for Transport Layer Security (TLS) encryption at no charge.

While Let’s Encrypt issues free and user-friendly SSL certificates, they do come with a notable limitation: their validity is restricted to just 90 days. These imply that they necessitate more regular maintenance than other certificates, which typically have validity periods ranging from 12 to 36 months.

Fortunately, Sophos Firewall simplifies the process by providing an automatic renewal feature, sending reminders 30 days prior to expiration.

Let’s Encrypt certificates support a wide range of firewall providers.
