Let's Encrypt free SSL is a great option, but has limits.
Let's Encrypt pros
- Completely free
- Auto-renews every 3 months
- DV level — fine for regular sites
Limits
- DV only — no company name
- Wildcard needs DNS validation
- Needs some tech skill (Plesk makes it easier)
When to buy a paid SSL
For banks, e-commerce and sites where company identity matters — get OV/EV.
