Here is a link to my Stanford Advanced Cybersecurity Certificate, Adobe Reader is required to see the verification as a legit certificate:

Link to Stanford Advanced Cybersecruity Certificate

Because of how Stanford Continuing Ed. does their certificate distribution, there is no way to offer you a direct link from their system. Only the signed PDF, which I have to self-host and distribute.

If you open this in Adobe Reader you will see a blue bar across the top that says "Certified by Office of the Registrar, Stanford University". If you just open it in your browser, you won't see that.
