A command-line tool and former web service for detecting the Heartbleed vulnerability (CVE-2014-0160) in TLS servers. Written in Go, it tests HTTPS and STARTTLS services and reports SAFE, VULNERABLE, or ERROR via exit codes.
Use cases
- check if my server is vulnerable to heartbleed
- test cve-2014-0160 on a hostname
- scan smtp or ftp servers for heartbleed via starttls
- script a heartbleed check with exit codes
- verify openssl patch was applied correctly
When to choose
- auditing legacy servers that may still run unpatched OpenSSL
- checking STARTTLS services like SMTP, IMAP, or FTP
- scripted or CI-based vulnerability checks needing exit codes
When to avoid
- scanning for modern CVEs or general TLS misconfigurations
- needing a maintained web-based test (the public site was discontinued in 2019)
- comprehensive vulnerability scanning beyond Heartbleed
