Turvallisuussertifikaatteja, or security certificates, are digital documents that verify the authenticity of a website or application. They are issued by trusted third-party organizations known as Certificate Authorities (CAs). These certificates use public key infrastructure (PKI) to establish a secure connection between a client and a server, ensuring data integrity and confidentiality.

There are several types of security certificates, each serving different purposes:

1. Domain Validation (DV) Certificates: These certificates verify that the applicant has control over the domain name. They are the most basic and least expensive type of certificate.

2. Organization Validation (OV) Certificates: These certificates provide additional verification of the organization's identity, including its legal existence and physical address. They offer a higher level of trust and security.

3. Extended Validation (EV) Certificates: These certificates provide the highest level of verification, including the organization's legal existence, physical address, and operational existence. They are indicated by a green address bar in web browsers, providing users with an extra layer of assurance.

Security certificates are essential for protecting sensitive data, such as personal information, financial transactions, and intellectual property. They help prevent man-in-the-middle attacks, phishing, and other cyber threats. By using security certificates, organizations can build trust with their users and comply with industry regulations and standards.
