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!


* 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.

Reviews From google play store

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.

Search and dicovery open ports and devices on your local networks . My favorite at the time being Apps like this are hard to find

"Unable to access device ARP table" am I doing something wrong? Stock android 10 (Pixel 2)

thnx for this app, Aaron. btw, I became aware that you got ripped off by some "source code thief" in the past, so I searched for "Who use my Wifi" ... looks to me that this has become a popular business model (and that thieves have become better at obscuring their activities)

I wanna know, what's up here, heavy discussion with Developer Aaron Wood, I didn't open the App, Aaron Wood, and You answer so kind to all this, sorry, many nonsensical Comments, I couldn't believe, that a strange Wish like a Payment (!?!), I still look for a good Ports canner, I'm running Win 7 Ultimate, on Computer, Mft's new Update Bundles are terryfying, my OS changes, and affects my Android, off course, I rated 5 stars, because I write about what I read here about the App, I am interested, I'll update my Review, I trust Aaron, Nice from him NOT to start Concepts with Payment, but you can for sure donate Money

won't find everything on the network every time. I don't know why. I've tried slowing the wait time down.

it is an excellent app but it would be better if it could also detect the connected devices when the hotspot is active

Port scanning does not scan due to remote access attacks. Your app need to be reviewed. May I send logs?

Great app, life saver, totally would recommend!

Those who can use this app properly will really enjoy it! Probably the best of its kind yet so simple!


requires following permissions on your android device.

approximate location (network-based)
Allows the app to get your approximate location. This location is derived by location services using network location sources such as cell towers and Wi-Fi. These location services must be turned on and available to your device for the app to use them. Apps may use this to determine approximately where you are.

view network connections
Allows the app to view information about network connections such as which networks exist and are connected.

view Wi-Fi connections
Allows the app to view information about Wi-Fi networking, such as whether Wi-Fi is enabled and name of connected Wi-Fi devices.

full network access
Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.
