Sectigo EssentialSSL Wildcard certificate is an advanced SSL/TLS solution that provides full security for one main domain and an unlimited number of subdomains. The Wildcard certificate allows for easy and effective domain security management, eliminating the need to issue separate certificates for each subdomain. It is based on strong asymmetric encryption with keys of at least 2048-bit length, which ensures compliance with the latest industry security standards.

Sectigo EssentialSSL Wildcard supports encryption algorithms based on both traditional RSA keys and modern ECC (Elliptic Curve Cryptography) keys, which offer better performance and shorter response times while maintaining the same level of security. Thanks to this, this certificate can be flexibly adjusted to the specific needs of the infrastructure, offering advanced cryptographic options. The certificate verification process is based on the Domain Validation (DV) mechanism, which means quick and easy confirmation of domain ownership, most often via e-mail or DNS record. This certificate is widely compatible with web browsers, mobile devices and servers, which guarantees trouble-free functioning in various environments.

An additional advantage is the financial guarantee offered by Sectigo in the amount of up to $10 000, which protects the certificate owner in the event of improper issuance of the certificate by certification authorities. This commitment emphasizes the reliability of this product and the reputation of the Sectigo brand, one of the largest and most trusted providers of SSL/TLS solutions in the world. The Sectigo brand, formerly known as Comodo, has a long-standing industry reputation for delivering reliable internet security solutions, ensuring the highest level of protection for websites and online services.

• Broad protection: Allows you to secure an unlimited number of subdomains at one level under a single root domain, eliminating the need to purchase and manage multiple SSL certificates.
• Advanced encryption: Supports both RSA and ECC (Elliptic Curve Cryptography) algorithms, ensuring high performance and security with cryptographic keys of at least 2048-bit for RSA and 256-bit for ECC, which meets the highest standards for data encryption.
• Compatibility with a wide range of devices and browsers: The certificate is recognized by over 99% of web browsers and mobile devices, including Android, iOS, Windows, and macOS platforms, ensuring a stable and secure connection on almost any platform.
• Fast Domain Validation (DV): The certificate is issued is based on quick and easy verification of domain ownership (Domain Validation), which allows for immediate implementation of protection, usually within minutes of domain confirmation.
• Perfect Forward Secrecy (PFS): The certificate supports Perfect Forward Secrecy technology, which increases the level of session security by ensuring that even in the event of a compromised private key, session keys used in the past cannot be decrypted.
• Financial guarantee: Offers a guarantee of up to $10 000, which protects users in the event of errors by the certificate issuer, providing additional financial security for website owners.
• Simple management: Thanks to the Wildcard function, the domain owner can add and remove subdomains without having to modify the certificate or re-issue it, which reduces the costs and time associated with managing SSL certificates.
• Reputation and trust: Sectigo, as one of the leaders in the industry certification, guarantees high quality and trust, which translates into strengthening the website’s reputation and the trust of its users.

Sectigo EssentialSSL Wildcard certificate security seal is a static graphic that website owners can place on their websites to visually confirm that their site is protected by an SSL certificate. While it is not dynamic, the seal still plays an important role in building trust with users and letting them know that connections to the site are secured with SSL/TLS encryption. The Sectigo security seal can be easily integrated into your website by adding it to a location of your choice, such as the home page, footer, or key areas such as login forms or transaction pages. It is a clear indicator that lets visitors know that their data is being transferred securely, even if the seal does not contain dynamic certificate information. Although the seal does not update automatically, its presence signals to users that the site is using a trusted SSL certificate from Sectigo, one of the world’s leading providers of certificate solutions.

Sectigo EssentialSSL Wildcard certificate is based on Domain Validation (DV), which is fast and automatic, allowing the certificate to be issued in a short time. After placing an order, Sectigo performs a verification process to confirm that the person or organization requesting the certificate has control over the main domain and all its subdomains. There are two validation methods available: email verification and DNS verification. In the case of the email method, a confirmation link is sent to one of the predefined email addresses assigned to the domain, such as admin@, administrator@, webmaster@, postmaster@ or hostmaster@. After clicking the link, control over the domain is confirmed. Alternatively, validation can be done using a DNS record. The user must create a specific TXT record in the DNS configuration of their domain, which will be automatically checked by Sectigo. Once successfully verified by one of these methods, a certificate is generated and issued, allowing immediate application of security to the main domain and all subdomains.

Important: Wildcard SSL certificates cannot be verified via file.

Wildcard feature in the Sectigo EssentialSSL Wildcard certificate allows you to secure not only your main domain, but also all of its subdomains with a single SSL certificate. With this feature, website owners can protect both the main domain (e.g. example.com) and any number of subdomains, such as mail.example.com, blog.example.com or shop.example.com, without having to purchase separate certificates for each of them. Wildcard SSL works by using the “*” symbol before the main domain, which means that all subdomains at this level will be protected. This feature is especially useful for companies and organizations managing multiple services or website sections that are available under different subdomains. This way, it is possible to simplify certificate management and reduce costs, because one SSL certificate protects the entire domain structure. Thanks to Wildcard, the certificate provides flexibility in securing dynamically changing subdomains, which is an ideal solution for organizations developing their Internet resources. This feature also increases the convenience and efficiency of SSL certificate management while offering the same level of encryption and data protection as traditional SSL certificates.

Sectigo EssentialSSL Wildcard certificate provides broad compatibility with almost all web browsers and mobile devices. Its SSL/TLS certificate is recognized by most popular browsers, such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera. Thanks to this, users using these browsers can be sure that connections to the secured website are safe and encrypted. In the case of mobile devices, the certificate is compatible with iOS and Android operating systems, which guarantees correct operation on a wide range of smartphones and tablets. In addition, the Sectigo EssentialSSL Wildcard certificate is supported by older versions of browsers, as well as older operating systems, which increases its universality and ensures that websites can function correctly on different types of devices, regardless of their up-to-dateness. Thanks to its high compatibility with browsers and mobile devices, this certificate is a reliable solution for companies and organizations that want to ensure secure connections on all devices used by their users.
