Sectigo SSL Wildcard certificate is an advanced and comprehensive security solution, offering protection for both the main domain and all of its subdomains at the same level in the DNS hierarchy, using a single certificate. As a product of Sectigo, one of the largest and most respected providers of digital certificates in the world, Wildcard SSL provides the highest standard of security, which is reflected in the wide trust in the industry. Sectigo certificates are compliant with CA/Browser Forum standards and have full support for all major browsers and mobile devices, which guarantees wide compatibility and trouble-free implementation in various environments.

This certificate offers the possibility of choosing between two advanced cryptographic algorithms: RSA and ECC (Elliptic Curve Cryptography). The RSA algorithm, with a key length of up to 4096 bits, is a widely used standard in cryptography, offering an excellent balance between security and performance. In turn, ECC, a modern cryptographic algorithm, is characterized by greater efficiency at lower key lengths (e.g. 256-bit), offering a higher level of security with fewer computing resources. Thanks to support for both of these algorithms, Sectigo SSL Wildcard allows for flexible adjustment of security to individual needs and IT infrastructure architecture. Encryption performed by Sectigo SSL Wildcard is based on 256-bit symmetric key sessions, which are agreed using asymmetric RSA or ECC keys. This makes this certificate offer the highest level of confidentiality of data transmission, protecting users against potential man-in-the-middle attacks, eavesdropping on communication, and protecting sensitive information such as login data, payment transactions or other confidential data. The Sectigo SSL Wildcard certificate validation process is based on Domain Validation (DV), which means that it is enough to confirm control over the domain in the verification process, thanks to which the certificate can be issued in a few minutes. This is an optimal solution for organizations that need to quickly implement SSL protection without having to provide identity documents or company information.

Sectigo SSL Wildcard also provides a high financial guarantee (up to $500 000), which is an additional level of protection against potential losses resulting from a certificate security breach. This guarantee is a proof of trust in Sectigo products and their reliability in data protection. This certificate is an ideal solution for companies with an extensive domain and subdomain structure, allowing for easy management of certificates and reduced administrative costs. With Sectigo SSL Wildcard, you can secure a comprehensive network infrastructure with minimal operational effort, while ensuring the highest security standards.

• Unlimited subdomains security: Sectigo Wildcard SSL Certificate allows you to secure an unlimited number of subdomains at the same level of the DNS hierarchy with a single certificate, eliminating the need to purchase separate certificates for each subdomain.
• Encryption based on the latest standards: The certificate supports both RSA (up to 4096 bits) and Elliptic Curve Cryptography (ECC), allowing you to choose the optimal cryptographic technology depending on your security and performance requirements.
• Fast Domain Validation (DV) process: Wildcard SSL Certificate is based on domain validation, meaning it is issued quickly after domain control is confirmed, without the need to provide ID documents or go through lengthy verification processes.
• Full browser and mobile compatibility: Sectigo Wildcard SSL is recognized by all major web browsers and mobile devices, including iOS and Android, ensuring seamless integration across platforms and minimizing the risk of displaying warnings about an untrusted connection.
• Integrated financial guarantee: The certificate is backed by a $500 000 financial guarantee, protecting against potential losses in the event of a security breach resulting from a certificate malfunction.
• Easy administration and cost savings: Using a single Wildcard certificate to secure multiple subdomains greatly simplifies the management of your SSL infrastructure, reducing the administrative and operational overhead associated with monitoring, renewing, and installing certificates.
• TLS Protocol for secure connections: Sectigo Wildcard SSL provides compatibility with the latest versions of the TLS (Transport Layer Security) protocol, ensuring high performance and security of data transmission, protecting against threats such as attacks man-in-the-middle.
• 24/7 Technical Support: The Sectigo Wildcard SSL Certificate is backed by 24/7 technical support, which provides assistance in the event of issues related to installation, configuration or certificate management, ensuring uninterrupted protection of the IT infrastructure.

Sectigo Wildcard SSL Security Seal is a graphical element that can be placed on a website to indicate that the site is protected by an SSL certificate issued by Sectigo. This seal builds trust with visitors by signaling that data transmission between users and the site is secured with encryption. The Wildcard DV certificate protects the main domain and all of its subdomains, meaning that the seal applies to the entire scope of secured elements within a given domain. Unlike more advanced certificates, the Wildcard DV offers a basic level of verification, focusing on fast and effective site security, which is sufficient for many standard applications. Integrating the seal into a website is a simple process of adding the appropriate HTML code provided by Sectigo. The seal can be placed anywhere on the page as a permanent element that confirms SSL protection, increasing the credibility of the site in the eyes of users.

The validation procedure for the Sectigo Wildcard SSL certificate is based on Domain Validation (DV), which consists of confirming that the certificate applicant has control over the domain they want to secure. This process is fast and automated, which allows the certificate to be issued within a short time after verification is completed. Validation begins with the submission of an application by the domain owner. Sectigo then sends an email to the address associated with the domain, such as admin@, administrator@, hostmaster@, postmaster@ or webmaster@. The applicant must confirm their control over the domain by clicking on the verification link in the received email. Alternatively, verification using DNS records is possible, where the applicant must add a special TXT record to the domain’s DNS settings. After verification by one of these methods, Sectigo automatically processes the information and issues a Wildcard SSL certificate, which can be immediately installed on the server. The process is simple and requires minimal administrative intervention, while providing rapid implementation without the need for additional documentation or audits.

Important: Wildcard SSL certificates cannot be verified via file.

The Wildcard feature in the Sectigo Wildcard SSL certificate allows you to secure not only your main domain, but also all of its subdomains at the same level of the hierarchy, without the need to issue separate certificates for each subdomain. This allows a single certificate to protect both the main site, e.g. ‘example.com’, and any number of subdomains, such as ‘mail.example.com’, ‘shop.example.com’ or ‘blog.example.com’. Wildcard works by placing a “*” symbol before the main domain, meaning that the certificate covers all subdomains in a given set. This feature is especially useful for organizations that manage multiple subdomains, allowing them to simplify SSL administration and reduce the costs associated with purchasing and maintaining multiple certificates. Wildcard SSL provides uniform encryption and authentication for the entire domain structure, which is crucial for the security of the network infrastructure and the consistency of certificate management.

Sectigo Wildcard SSL certificate features broad compatibility with web browsers and mobile devices, making it a universal solution for ensuring secure connections across platforms. It is recognized by all major web browsers, such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera, ensuring that users of sites secured with this certificate will not encounter any warnings about the lack of trust in the site. In addition, this certificate is fully compatible with mobile devices, including smartphones and tablets running on Android and iOS, ensuring secure connections also in mobile environments. Thanks to support for the TLS protocol, Sectigo Wildcard SSL offers stable and reliable encryption on any platform, regardless of the device on which the site is displayed.
