1. An apparatus comprising:

  • a memory;

    a security agent, at least a portion of which is to be implemented in a hardware processor, to extract and examine a certificate, wherein the certificate is used in authentication of a first secure communication channel with a domain,wherein the security agent stores in a non-transitory computer readable medium a relationship indicator between the domain and the certificate based on the detection of a pinning indicator within the extracted and examined certificate used in authentication of the first secure communication channel, wherein the detection of the pinning indicator comprises comparing the value of a field of the certificate with a predetermined value, and wherein data to be communicated over a second secure communication channel with the domain is secured via Secure Socket Layer (SSL) or Transport Layer Security (TLS) based on the stored relationship indicator between the domain and the certificate; and

    wherein the relationship indicator comprises a pin in the certificate which records the domain, the certificate, and pin information into the memory for either the security agent or a web browser to enforce the pin.
