INSTEAD OF NMAP

A simpler Nmap alternative for Windows

For when the job is: Find out which ports are open on a host or across a subnet.

Nmap is the better scanner, and this page is not going to pretend otherwise. It fingerprints operating systems, identifies service versions, and runs a scripting engine that can do far more than report open ports. If you are doing security assessment work, use Nmap.

What CySecTek offers is the common case without the setup. It answers "what is open on this host" and "what is open across this subnet" using ordinary Windows sockets — a plain TCP connect and UDP probes — so there is no Npcap driver to install, no administrator rights needed, and nothing left behind on a client machine you were only visiting.

What CySecTek does here

  • Scans a host, a CIDR block, a range, a comma-separated list, or a file of targets.
  • Multi-host targets are swept for live hosts first and only those are scanned, because a /24 is 254 addresses and usually a dozen machines.
  • Results group by host with its hostname, MAC vendor and open-port count, and export to CSV, JSON or plain text.
  • Adjustable parallelism, retries and timeout, and a scan you can stop.
  • Optional banner grabbing for SSH, HTTP, FTP and SMTP.
  • No driver and no elevation — it runs as an ordinary user on a locked-down laptop.

When to keep using Nmap

  • OS fingerprinting and service-version detection. CySecTek reports the IANA service name for a port, which is a guess from the number, not an interrogation of what is really listening.
  • The Nmap Scripting Engine, and anything built on it.
  • SYN / half-open scanning and other raw-socket techniques — CySecTek completes the TCP handshake, which is slower and shows up in logs.
  • Serious security assessment, penetration testing, or anything where completeness is the point.

Questions

Does it need Npcap or WinPcap?
Not for port scanning — that uses ordinary sockets. Npcap is only needed for the two features that read raw frames: LLDP/CDP switch-port discovery and packet capture.
Does it need administrator rights?
No, not for scanning. A connect scan is something any user can do.
How fast is a /24?
It depends on the port list and your network, but the sweep-first approach is what makes it practical: only hosts that answered ARP, ICMP or a TCP knock get scanned, so you are usually scanning a dozen machines rather than 254 addresses.
Is this a replacement for Nmap?
No, and it is not trying to be. It is the quick answer for a field engineer; Nmap remains the right tool for assessment work.
