Sectigo® Certificate Authority (CA)
Sectigo® is a globally recognized Certificate Authority (CA) that provides digital security solutions for businesses, organizations, and individuals. Formerly known as Comodo CA, Sectigo® rebranded in 2018 and has since expanded its product offerings to include a wide range of cybersecurity solutions.
The company's primary focus is on securing websites, applications, and online communications through encryption, authentication, and data integrity technologies.
SSL/TLS Certificates
One of Sectigo®’s core offerings is its range of SSL/TLS Certificates, which are used to encrypt data transmitted between users and websites, ensuring privacy and protection against cyber threats. These Certificates come in different validation levels to meet various security needs.
Domain Validation (DV) Certificates provide basic encryption and are ideal for personal websites and small businesses. Organization Validation (OV) Certificates require business verification, offering a higher level of trust for corporate websites. Extended Validation (EV) Certificates provide the most rigorous authentication, displaying a highly visible trust indicator, such as a green address bar, to assure users of the website’s legitimacy.
Additionally, Sectigo® offers Wildcard SSL Certificates to secure a domain and its subdomains under one Certificate, as well as Multi-Domain (SAN) Certificates, which allow multiple domains to be protected with a single solution.
Code Signing Certificates
For software developers and organizations distributing applications, Sectigo® provides Code Signing Certificates that ensure software integrity and authenticity. These Certificates are essential for preventing tampering and malware infections, giving users confidence that the software they download has not been altered. Sectigo® offers Code Signing solutions for a variety of platforms, including Microsoft, Java, and Adobe, helping developers establish trust with their users.
E-Mail Security & S/MIME Certificates
To combat email-based cyber threats such as phishing and spoofing, Sectigo® offers Secure/Multipurpose Internet Mail Extensions (S/MIME) Certificates. These Certificates encrypt email communications and allow users to digitally sign their messages, ensuring that emails remain confidential and originate from verified senders. By implementing S/MIME Certificates, businesses can enhance their email security and protect sensitive information from being intercepted or manipulated.
Private CA and Enterprise PKI Solutions
For businesses that require greater control over their digital security infrastructure, Sectigo® offers Private CA and Enterprise Public Key Infrastructure (PKI) solutions. These services enable organizations to establish their own Certificate authority, allowing them to issue and manage digital Certificates tailored to their internal needs. Whether for employee authentication, secure internal communications, or IoT device management, their PKI solutions provide scalable and customizable security.
Web Security and Website Protection
In addition to SSL/TLS Certificates, Sectigo® provides a suite of web security services designed to protect websites from cyber threats. Its Web Security Platform includes malware scanning, vulnerability assessments, and automatic remediation tools to detect and neutralize security risks.
The company also offers website backup and recovery services to help businesses restore lost or compromised data in the event of an attack. Furthermore, its Web Application Firewall (WAF) defends against common online threats such as SQL injection, cross-site scripting (XSS), and distributed denial-of-service (DDoS) attacks.
IoT Security Solutions
As the Internet of Things (IoT) continues to grow, Sectigo® provides security solutions designed to protect connected devices from cyber threats. By issuing digital Certificates for IoT devices, Sectigo® enables secure authentication and encrypted communication between machines, preventing unauthorized access and data breaches. This is particularly crucial in industries such as healthcare, manufacturing, and smart infrastructure, where secure IoT communication is essential for operational safety and efficiency.
