A handy systems and security-focused tool, Port Authority is a very fast port scanner. Port Authority also allows you to quickly discover hosts on your network and will display useful network information about your device and other hosts.

One of the fastest port scanners with host discovery on the market! Host discovery is typically performed in less than 5 seconds. If the device you're scanning drops packets, it takes about 10 seconds to scan 1000 ports. If the device you're scanning rejects packets, it takes less than 30 seconds to scan all 65,535 ports!

Features

* Heavily threaded, no more waiting for results one at a time
* LAN host discovery
* Public IP discovery
* MAC address vendor detection
* LAN/WAN host TCP port scanning
* Custom port range scans
* Open discovered HTTP(S) services to browser
* Lightweight service fingerprinting (SSH/HTTP(S) server type and version)
* DNS record lookups supporting almost every record type
* Wake-on-LAN for LAN hosts

How are scans so fast?

This application makes heavy use of threading. Because most of the operations performed are I/O bound a lot more threads can be used than the number of cores on a device. In fact, one of the most intensive parts of the application is updating the UI during scans. This has gone through many optimizations but still remains a bit of a hotspot.

I have a lower end and/or older device, will this work?

Absolutely! Just lower the number of threads that are used for port scans in the settings. I'm always working on improving the efficiency and memory footprint of the application, and things have been greatly improved since the original version!

I keep getting crashes when scanning a large range of ports

The crash is most likely an out of memory exception that is occurring due to using too many threads. Lower your port scan thread count in the settings. The right value will be highly dependent on the device and its hardware.

I'm getting a warning that says this application is trying to send email

A few users have reported that a warning pops up on their device, warning them that this application is trying to send mail. This is caused by various security software so you can be assured (or just look at the code yourself) that I'm not sending mail.

Some security software looks at where traffic is coming and going from the device and takes certain actions for certain cases. If you're running any kind of port scan that includes port 25 (SMTP) this will most likely be flagged. Even though no data is being sent to that port the security software will see an outbound connection to an SMTP service and throw up a warning. Obviously this is a very bad check but some security tools are better than others and may actually look for data flowing out to port 25 to see if there's really anything happening.

I'm not finding some of the hosts/devices on my LAN

If you're finding that some devices aren't responding in time you should increase the host scan timeout setting, just be aware that it will cause host scans to take longer. In some cases it may be worth trading time for accuracy.

I'm not finding open ports that I know are truly open

You can now adjust the timeout for connections made to ports when performing either LAN or WAN scans. If you're scanning something over WAN (mobile network if you're using a cell phone) please be aware that scanning is best effort. Mobile carriers may detect that a real port scan is occurring and apply traffic shaping dynamically, or they may just start terminating the connections entirely. Additionally, if you happen to have poor signal or to not have 4G the quality of the network connection may be so poor that you'll need to have a fairly high timeout in order to tolerate latency spikes.

    Very cool, nice fun!!! Need to use good judgement and becarefull what you do, and where. I'm trying to learn code and all this stuff. So next time my email, then bank and couple other problems arise, I can understand and read enough to do something about it. Or help someone else. Great job, Port Authority!!¡!!

    Excellent. Does exactly what I need, which is to tell me how many and what are all the devices that share your Wi-Fi network. It's super easy to use, has no intrusive ads and it's free. Many thanks to the dev for such a great app, and congrats on a job well done.

  3. Ken Guest-avatar

    Ken Guest

    It works well for what it is, but it could be improved by getting rid of the drum picker for specifying the port range and having a normal text box entry field instead. Currently trying to scan ports 8000 to 9000 only is... suboptimal.

  4. Rudi On The Line-avatar

    Good for displaying host details - useless for finding ports. If you want to scan a certain range of ports you have to scroll - YES SCROLL - through the 65k ports, TWICE, to set the upper and lower limits. Why not just allow a number entry?

  5. Todd Hayward-avatar

    Todd Hayward

    Its quite good. However, the one feature I really want that this version does not have is the ability to specify a remote IP range to scan. As a network / systems admin I need to be able to discover hosts/devices on remote address ranges that are part of the networks I am connected to. I would donate to the dev for the inclusion of that option.

    Excellent android conversion of some stuff found on pc though the wake couldn't be seen to do anything on my laptop maybe it was the software that disappeared from my desktop but maybe it worked and did what i should.

    inconsistencies: perform a host scan, see a host, it tells me the vendor. use the same app on a different device and that same host as before has unknown vendor. sorting is strange: sorts by ip by default, with options to do it via hostname or vendor. no way to return to ip order. minor things. reply: host 'a' vendor shows on device 'x' but does not show on device 'y'. different db going to different phones? pie ok (s8), lollipop (s4) not. UPDATE: external ip function fixed

  8. George Marshall-avatar

    I have to commend the responsibility and the knowledgeability of the developer here, even though this app does not have what I wanted. I was looking for a way to apply restrictive filters to block all traffic on specified ports to either an IP address or a wildcard (*) for ALL IP addresses. I wanted this because some of my Android 9 system apps are making unencrypted connections through Port 80 http! BIG security risk. Anyway, I wish more developers were like you. Best of luck!

    handy tool for network mapping at high level, it was only after reading another reviewers notes that I realised you could text-entry the scrollable port entry though. (tap the number in the scroll and you should be able to edit the number). Doesn't remember the discovered ports after you leave the node / ports list and go back to the network nodes list. Doesn't seem to indicate tcp / udp either.

    Great app wasnt able to use my printer as encapsulated ethernet took the port but runnin 65k i ports system to find embedded systems was great with mac addresses and ips thank you!
