HackerTarget TCP Port Scan review
A low-cost hosted scanner for common-port checks, automation, and firewall exposure analysis.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
HackerTarget TCP Port Scan is a hosted web and API tool for checking TCP exposure on Internet-facing hosts and firewalls. It accepts IPv4 addresses, IPv6 addresses, hostnames, and IP ranges, then reports whether scanned ports are open, closed, or filtered. The free scan covers ten common TCP ports, making the product a practical fit for individuals and small teams that need a quick view of basic network exposure without deploying scanning software.
The published plans show a straightforward progression from basic checks to broader and recurring scanning. Starter costs $10 per month when billed annually and adds Nmap scanning, OpenVAS scanning, standard scans, and Tools API access. Pro costs $25 per month when billed annually and adds scheduled Nmap and OpenVAS scans plus increased scan quotas. Business costs $50 per month when billed annually and adds Zmap port scanning and increased scan quotas. Enterprise includes large-scale scanning, a Zmap port scanner, and Tools API access. Scheduled scans and target lists are suited to teams that need repeatable monitoring rather than one-time checks.
Its main strength is focused hosted access: users can run scans through the web or automate queries through the HTTP API, while firewall exposure analysis adds context to port-state results. The scope remains deliberately narrow. The named TCP Port Scan is centered on common-port checks, and the published category specifications show plain-text exports, no verified service detection, and no operating-system detection. Choose HackerTarget for low-cost TCP exposure checks, API-driven queries, and a path to scheduled or broader scanning. Choose another product when deep service fingerprinting, operating-system discovery, or a wider integration ecosystem is central to the workflow.
