StartSSL&#x27;s offering of free domain certs were ahead of their time and LE is taking it a step further. Having said that, there&#x27;s no cost attached w&#x2F; LE in cases where revoking a cert is required (ex: security vuln). If managing a sizable portfolio of doms w&#x2F; StartSSL Class 1 Certs, missed their fee structure, you&#x27;re in for a surprise.
