What is UCC SSL? How Does It Works?

UCC SSL certificate is ideal for your multiple domains and subdomains to provide the highest encryption and comes with different types of validation methods.

In the current digital milieu, safeguarding online assets has become a pressing concern for individuals and businesses alike. The rising incidences of cybercrime and data breaches have necessitated the implementation of formidable security measures, including the use of SSL (Secure Sockets Layer) certificates.

While traditional SSL certificates are engineered to secure a singular domain, Unified Communications Certificate (UCC) SSL proffers an avant-garde solution for entities requiring the security of multiple domains. UCC SSL is an optimal option for organizations with a plethora of websites or subdomains as it has the ability to safeguard up to 100 domain names with a singular certificate, thereby providing a cost-effective and efficacious security solution.

According to a recent report by Cybersecurity Ventures, the global cost of cybercrime is estimated to reach a staggering $6 trillion in 2021. This momentous figure emphasizes the exigency for preemptive security measures in safeguarding online assets. UCC SSL offers an additional layer of protection, ensuring the encryption and security of all domains and subdomains from potential cyber threats.

This blog post aims to explicate the UCC SSL concept, its mechanism of operation, and the manifold advantages of its implementation in securing multiple domains. Therefore, brace yourself for a highly illuminating and technically advanced exploration of the intricacies of UCC SSL.

What is UCC SSL?

A Unified Communications Certificate (UCC), also referred to as a Subject Alternative Name (SAN) certificate, is a type of digital certificate that offers a robust and flexible solution for securing multiple domain names and hostnames with a single certificate.

Designed specifically to cater to the needs of organizations using Microsoft Exchange or Office Communications servers, UCC SSL certificates enable the secure encryption and authentication of both internal and external domain names.

UCC SSL certificates utilize advanced encryption algorithms, such as the RSA, ECC, or DSA, to secure communication channels and prevent unauthorized access to sensitive data transmitted between the server and client. Additionally, they use the Subject Alternative Name (SAN) extension to include all domain names and hostnames that the certificate is intended to secure.

How Does A UCC SSL Certificate Work?

When you purchase a UCC SSL certificate, you provide a list of the domains and subdomains you want to secure, which are then added as SANs to the certificate.

When a client connects to a server that is using a UCC SSL certificate, the client’s browser first checks the validity of the certificate. The browser verifies that the domain name in the URL matches one of the SANs listed in the UCC SSL certificate. If the domain name matches, the browser establishes a secure, encrypted connection with the server using SSL/TLS protocols.

Under the hood, UCC SSL certificates work by using the Server Name Indication (SNI) extension in the SSL/TLS handshake protocol. The SNI extension allows the client to specify the hostname of the server it wants to connect to, so the server can present the appropriate certificate. In the case of a UCC SSL certificate, the server presents a certificate with multiple SANs, allowing the client to securely connect to any of the listed domains or subdomains.

UCC SSL Certificate Features

1. Multiple Domain Support:

One of the key features of a UCC SSL certificate is its ability to secure multiple domains and subdomains with a single certificate. This makes it a convenient option for businesses with multiple websites or subdomains to secure. By consolidating all certificates into one, businesses can save time and reduce costs associated with certificate management.

2. SANs Support

UCC SSL certificates use Subject Alternative Names (SANs) to list all the domains and subdomains that are covered by the certificate. This allows for flexibility in securing multiple domains and subdomains with a single certificate. SANs can also be added or removed from the certificate over time, giving businesses the flexibility to adjust their security needs as their website evolves.

3. Encryption Strength

UCC SSL certificates typically offer high-level encryption, typically 256-bit, which ensures that all communication between the server and the client is secure and cannot be intercepted by third parties. This level of encryption provides strong protection for sensitive data such as credit card information or login credentials.

4. Easy Installation

UCC SSL certificates are easy to install and manage, even for businesses that have limited technical expertise. Once the certificate is installed on the server, it will automatically secure all the domains and subdomains listed as SANs. This eliminates the need for individual certificate installation and management.

5. Flexible Validation Options

UCC SSL certificates offer flexible validation options to suit the needs of different businesses. Domain Validation (DV) certificates are ideal for businesses with simple websites, while Organization Validation (OV) certificates are recommended for websites that need higher authentication compared to DV certificates. Extended Validation (EV) certificates are the most comprehensive and recommended for businesses that need the highest level of security and trust.

6. Compatibility

UCC SSL certificates are compatible with all major web browsers and operating systems, making them a reliable choice for businesses that need to ensure that their website is accessible to all visitors. This compatibility ensures that visitors can access your website securely, regardless of the platform or device they are using.

7. Trustworthiness

UCC SSL certificates are issued by trusted Certificate Authorities (CAs) that have undergone rigorous security audits and comply with industry standards. This ensures that visitors to your website will trust the security of your website and are more likely to transact or share sensitive information on your site.

Conclusion for UCC SSL Certificate

In conclusion, UCC SSL certificates are an effective solution for securing multiple domains under a single certificate. With UCC SSL, you can easily secure up to 100 domains with just one certificate, making it a cost-effective option for businesses with multiple domains to secure. Additionally, UCC SSL certificates come with the same level of encryption and validation as traditional SSL certificates, ensuring that all domains and their associated subdomains are protected against malicious attacks and unauthorized access.
