Affiliate Disclosure

Last updated: January 2026

The Short Version

Some links on FixMyCert are affiliate links. If you purchase a course or resource through these links, I earn a commission at no additional cost to you. I only recommend resources I personally use and believe provide genuine value to PKI and TLS learners.

What This Means

FixMyCert participates in affiliate programs with educational course providers. When you click on certain links and make a purchase, I may receive a small commission. This commission comes from the course provider, not from you—you pay the same price regardless of whether you use my link.

These commissions help support the time and effort that goes into creating and maintaining FixMyCert's free educational content, including over 50 interactive demos, 90+ guides, and 10 runbooks.

How I Choose What to Recommend

My recommendations are based on quality, not commission rates. Before recommending any resource, I consider:

  • Educational value: Does this resource genuinely help people understand PKI/TLS concepts?
  • Instructor credibility: Is the instructor qualified and respected in the field?
  • Practical application: Does it include hands-on labs, real examples, or tools you can use on the job?
  • Personal experience: Have I used or reviewed this resource myself?

Current Affiliate Relationships

As of January 2026, FixMyCert has affiliate relationships with:

Practical Networking (pracnet.net)

I recommend Ed Harmoush's "Practical TLS" course on the Learning Resources page and in relevant TLS guides. FixMyCert visitors receive an exclusive 50% discount with code FixMyCert.

Amazon Associates Program

I recommend select books through Amazon affiliate links, including "Bulletproof TLS and PKI" by Ivan Ristic. As an Amazon Associate, I earn from qualifying purchases.

This list will be updated as new affiliate relationships are established.

Discount Codes

When I share discount codes (like FixMyCert for 50% off Practical TLS), these are genuine discounts negotiated for FixMyCert visitors. The discount comes off the regular price—you save money, and I earn a commission on the discounted sale. It's a win-win.

Where Affiliate Links Appear

Affiliate links on FixMyCert are always disclosed. You'll find them:

  • •On the Learning Resources page (with full disclosure at the top)
  • •In "Want to go deeper?" callouts within relevant guides (with disclosure text)
  • •On the homepage course recommendation (with disclosure text below)

Your Trust Matters

I built FixMyCert to help engineers understand PKI—not to make affiliate sales. The free content will always be the focus. Affiliate recommendations are an additional resource for those who want structured, in-depth courses beyond what I can provide for free. If I ever recommend something that doesn't meet my standards, please let me know.
