How Extended Validation(EV) & Wildcard Certificates Provide Multiple Layer Of Online Protection

SSL Certificate acts as a backbone of the Internet security system. It provides an encrypted link between a browser and a server, which helps in transferring or sharing data in encrypted form to keep the data integral and secure from falling in the wrong hands and from being misused. There are many types of SSL certificates available in the market, but it depends upon the requirement of the applicant, what level of SSL certificate would suit him the best. Higher the security required, higher the level of SSL certificate is needed. Various SSL certificates are divided into two groups on the basis of validation level and secured domains and sub-domains:

Validation level
Domain Validation aCertificate
Organization Validation Certificate
Extended Validation Certificate
Domain and sub-domain
Single Domain Certificate
Wildcard Certificate
Multi-domain Certificate


In this article, we will discuss Extended Validation Certificate (EV) and Wildcard certificate and how these certificates provide multiple layers of online protection.

EV SSL certificate:  EV stands for Extended Validation Certificate and it involves strict selection process of validation to make sure that the entity requesting for this certificate is legal and genuine. If a website is secured with a certified EV SSL certificate, it will be indicated by a Green colored address bar. Similar to Wildcard Certificate, Extended Validation Certificate is also used for websites prefixed with https:// and also for software that verifies legal entity, which controls the software package or website itself. To obtain EV Certificate, CA (Certification Authority) will verify the identity of the applicant and if the information provided by the entity is correct then the certificate is issued. Verification here is very important because EV certificate provides a higher level of security.

Wildcard certificate: If you own a domain and multiple subdomains, and you want to secure them all, instead of buying a certificate for every single domain and subdomain, you can buy Wildcard certificate, which will secure an unlimited number of subdomains but to a specific level. Along with providing security to multiple domains and subdomains, it will also save your time and money, which you would have wasted in buying and installing multiple certificates for every single domain and subdomain.

Technically, we can say that a Wildcard Certificate is a public key certificate and it can be used with numerous subdomains of a domain. The primary use of this certificate is to secure website prefixed with https://. A single Wildcard certificate works for your convenience and saves a lot of time, but it also protects or secures the main domain as well as its subdomain at the same time.
