## Verdict

The deciding factor is what you need to manage. Pick ZeroSSL for free 90-day certificates and straightforward ACME automation, or for a published subscription with unlimited 90-day certificates. Pick Sectigo if you need to buy OV or EV certificates directly, or want Certificate Manager Pro to discover existing public certificates and manage renewals across providers. ZeroSSL also offers OV, EV and enterprise lifecycle management through its HID Global enterprise offering, so those needs do not rule it out; they require a separate enterprise inquiry.
