TLSX is a fast and configurable TLS grabber written in Go that collects and analyzes TLS-based data from hosts. It supports multiple TLS connection modes, probes for certificate details, and TLS fingerprinting via JARM/JA3.

Use cases

• grab TLS certificates from a list of hosts
• collect subject alternative names and certificate details from servers
• compute JARM and JA3 TLS fingerprints
• detect TLS misconfigurations across a network
• enumerate SANs and CNs during reconnaissance
• scan hosts on ASN, CIDR, IP, or URL inputs for TLS data
• output TLS data as JSON for pipelines

When to choose

• you need fast, scriptable TLS data collection at scale
• you want TLS fingerprinting like JARM/JA3 in a CLI workflow
• you need JSON/TXT output for automation pipelines
• you want flexible TLS connection modes and cipher/SNI control

When to avoid

• you need deep TLS vulnerability exploitation rather than data collection
• you want a GUI-based certificate inspector
• you need continuous certificate monitoring with alerting rather than on-demand scanning
