Cert Spotter vs CRYPTAS Publicly Validatable Certificates: 2026 Comparison

Security teams managing external-facing domains should use Cert Spotter to catch unauthorized TLS issuance before attackers weaponize it; the tool monitors Certificate Transparency logs continuously and costs nothing, removing budget friction from what should be table-stakes threat detection. The 1,132 GitHub stars and sustained maintenance reflect real adoption among teams that treat cert monitoring as preventive rather than reactive. Skip this if your threat model assumes attackers won't bother with certificate abuse, or if you need policy enforcement and revocation workflows built in; Cert Spotter alerts you to the problem but leaves remediation to you.
