Why use our Port Scanner with Nmap?
Fast top-port scans for quick insights
Run scans in just minutes across the most common ports to get an immediate picture of exposed services, without slowing down your workflow. Unlike raw Nmap, you don’t need CLI skills or manual setup.
Deep, full-range scans when you need them
Switch to full TCP or UDP scans - up to all 65,535 ports - for a thorough view of your attack surface. It’s perfect for uncovering forgotten services or shadow IT, and you don’t have to write commands or juggle scripts.
No setup or installation
Forget CLI commands, local installs, or script maintenance. Our cloud-hosted scanner works fully online, comes preloaded with Nmap’s most powerful options, and delivers consistent, accurate results without firewall or egress rule headaches.
Results you can act on
Export your findings in CSV, JSON, or PDF, and feed them directly into vulnerability scanners, Pentest Robots, or automation workflows. Share them easily with clients, collaborators, or stakeholders. Every scan produces a professional, client-ready report, which raw Nmap outputs don’t give you out of the box.
Scalable for large environments
From single hosts and domains to bulk IP ranges, our online port scanner with Nmap adapts to your scope. Run scheduled or parallel scans with notifications, use API access for automation, and integrate results into your workflows without extra scripting. Stay efficient at any scale.
A fit for modern workflows
Our Port Scanner is the starting point for comprehensive security testing. Use it to map your attack surface, verify firewall rules, and feed results directly into our Website Scanner or Network Vulnerability Scanner. For internal targets, use our VPN Agent to test securely behind firewalls.
Direct integration
Feed results into Pentest Robots, API-driven workflows, or other proprietary tools to streamline discovery through remediation. Combine with scan templates to run multi-step, repeatable sequences and turn port scans into full vulnerability assessments, without manual handoffs.

Customer reviews
Simple, highly centralized vulnerability management platform with multiple tools
We recently started using PenTest-Tools for our vulnerability scanning. This tool combines multiple scanning capabilities into a single platform, allowing us to centralize our vulnerability management process. By consolidating various tools into one, it has become much easier to manage and monitor the overall picture of our vulnerability management efforts. Additionally, PenTest-Tools offers an integration feature with JIRA, which helps us address findings more efficiently. The configuration of the tool is simple and straightforward, and the support team is also very good at providing prompt feedback and solutions.

Port Scanner with Nmap FAQs
What is a port scanner?
A port scanner tool is part of a family of port scanning tools used in penetration testing and network security. It checks network ports on a target system (by IP address or hostname) to reveal open, closed, or filtered ports. This helps map exposures, identify vulnerable network services and assess security risks, making it perfect for deciding where deeper tests or network scanning should follow.
How is this different from running Nmap locally?
You still get the same open-source Nmap engine that professionals trust, but without needing to install it on Linux, Microsoft Windows or other operating system providers. Our hosted version runs in the cloud, so there's no CLI required. All you need is a browser and you get instant results ready for integration into your workflow.
Can I scan UDP ports?
Yes, you can run full TCP port and UDP scans (e.g. 22 - SSH Secure Shell, 3389 - RDP Remote Desktop Protocol) to cover services like DNS, FTP, and POP3, which gives you comprehensive visibility across essential services like web servers or email servers.
What formats can I export results in?
Export in JSON, CSV, and PDF. These can be shared with clients, used with various integrations and preferred workflows, or matched against firewall rules and port forwarding setups to validate segmentation.
Can I quickly scan all open ports without installing anything?
Yes. Use our open port scanner to launch scans straight from your browser, no setup needed.
Can I run a full TCP/UDP port scan online?
Yes, you can. Run full 65,535 TCP scans, add UDP if needed, and immediately check port status across your targets.
Does this work on large IP ranges or hardened networks?
Yes. It supports bulk scanning across IP ranges and, thanks to its cloud-based hosting functionality, bypasses firewall or local egress restrictions that often block CLI scans.
Is this scanner as good as Nmap?
It is powered by Nmap itself. It has the same accuracy, with extra perks like web-based access, added automation, exports, and integration into broader workflows.
What’s the best online port scanner?
In our experience the best tool combines speed, trust, and integration, and is usable by network administrators all the way to dedicated pentesters. That’s exactly what you get with our Port Scanner with Nmap.
How to scan open ports without installing Nmap
Try our online port checker, powered by Nmap. You get the same power, but without any downloads, or maintenance. It’s ideal for rapid checks from any network or platform (including Telnet or SSH-based testing environments).
Can I run a port scan from my browser?
Of course you can launch full port scans (TCP, UDP, closed ports or specified ports) right in your browser. It’s the easiest way to assess network ports or check a router or remote host without needing terminal access, troubleshooting or fiddling with command lines.
What scanning techniques does this tool use?
The Port Scanner uses TCP SYN scans, full TCP connect scans, and can be configured to test UDP. This approach gives you coverage across standard scanning techniques and helps detect unauthorized access to services.
Can I check SSL-protected services?
Yes. If your target port supports SSL/TLS, the Port Scanner attempts to capture and report certificate details, helping you assess encryption legitimacy.
Can this replace an IP scanner?
Yes. While traditional IP scanners just ping addresses, our Port Scanner checks actual listening ports and services, and delivers a real-time view of active network services, which is much richer than basic ping sweeps.
