HPKP Reports, the ultimate protection

With HPKP you can protect yourself from threats in the PKI ecosystem

Our Platform

HTTP Public Key Pinning is a controversial mechanism that provides site operators an incredibly powerful defense mechanism. With the ability to 'pin' public keys you can protect yourself from rogue certificates issued by a hostile CA.

The mechanism is controversial though. With such a huge amount of power, and an equal amount of complexity in deploying it right, many sites have struggled to do it right and talk of deprecation is circulating. Chrome has already removed support for the HTTP header in January 2019.

Enabling HPKP Reports

Whilst enabling HPKP is easy, you simply return a the HTTP response header 'public-key-pins', knowing which values to pin and why can be extremely difficult.

Pinning at the leaf, intermediate or root levels offer varying degrees of protection and difficulty in maintaining the policy. Understanding which you should pin at and why, if you should pin, is a task for those with extensive experience in the Web PKI.
