TLS/SSL Certificate

TLS/SSL (Transport Layer Security/Secure Sockets Layer) certificates are digital certificates used to establish a secure, encrypted connection between a web server and a web browser or other client application. They provide an essential layer of security by encrypting all data transmitted between the server and client, preventing eavesdropping and tampering with data in transit.

TLS/SSL certificates are issued by trusted third-party organizations called Certificate Authorities (CAs). When a user visits a website secured with a TLS/SSL certificate, their browser checks to ensure that the certificate is valid and has been issued by a trusted CA. If the certificate is valid, the browser will establish a secure connection with the server, allowing encrypted communication.

TLS/SSL certificates come in different types, such as Domain Validated (DV), Organization Validated (OV), and Extended Validation (EV), each with varying levels of validation and trust. A DV certificate verifies that the domain owner controls the domain name, while an OV or EV certificate requires additional verification of the organization's identity and ownership. EV certificates provide the highest level of trust and are displayed as a green address bar in the browser.

ThreatNG Security can help organizations manage TLS/SSL certificates by discovering all certificates in use, monitoring them for expiration and vulnerabilities, providing security ratings, and offering guidance on remediation. This can help organizations maintain an up-to-date inventory of their certificates, ensure prompt renewal or replacement, prioritize certificate management efforts, and implement best practices for TLS/SSL security to protect against threats.
