Our Slitheris network scanner software is free for 50 network devices, making it 100% free to use for most home users, most home labs, very small networks, and classroom settings. And because Slitheris keeps scanning after the first 50 devices it finds, you can evaluate it on various networks without a trial license. Slitheris Network Discovery for Windows is a new premium next-generation network scanner, capable of gathering a wide array of information from network devices without credentials or agents. You’ll get more information than any free Windows-based IP scanner. And there’s no need to configure remote PCs, servers or other network IoT devices. Because of this, it’s extremely useful for both organizations and MSPs (Managed Service Providers) or IT providers who need to visit numerous customer networks and sites. In fact, because MSPs have been our initial focus, it’s perfect for MSPs scanning multiple customer sites needing quick network overviews.

Credential-free and Agentless Windows OS Detection & Fingerprinting

The vast majority of network scanning software packages require some type of credentialed access to remote devices to detect operating systems. However, using TCP/IP stack fingerprinting and other technologies, Slitheris Network Discovery can identify a wide array of operating systems without credentials or authentication, including Windows (and its Edition), Linux, iOS, and Android. Slitheris can even scan for other details related to the operating system such as Windows Uptime, Cold Boot Time, Time of Day and Domain/Workgroup names, and distinguishes between Domain and Workgroup types, all without needing authentication or credentialed access. This saves the time and frustration trying various usernames and passwords or having to visit PCs and servers in person. Managed Service Providers and other IT Providers will particularly appreciate this unique feature.

Most operating systems & other information are from remote devices normally requiring authentication.



Device Type Identification & Detection Hints

Slitheris provides an educated guess of device type by gathering dozens of attributes from each device during the probing process and comparing them to a Device Type Definitions DB, similar to how anti-virus software detects viruses. Although this feature is currently experimental, new methods are in development to much more accurately identify many more types of devices.

Device Age Estimation

As network devices age, they can become less secure and use more power than their newer counterparts, not to mention have fewer features and be less manageable. Some organizations replace important network devices every 5 years or so and sometimes in-house documentation doesn’t exist or has gotten lost over time. Using algorithms derived from various sources, Slitheris has the unique ability to estimate the year any network device was made, requiring just a MAC address to do so. Although most accurate with popular brands such as Cisco, HP, Dell, Apple, Samsung, etc, it’s also more accurate with newer devices made within the past year and older end-of-life devices 5 years or older.

More Device Names

While many IP scanners show IP addresses in place of Device Names, we designed Slitheris from the ground up to use at least ten different possible sources for deriving device names.

SMB Security

Due to the WannaCry (AKA NotPetya) ransomware that used the NSA’s EternalBlue vulnerability in 2017, a special SMB (Server Message Block) security feature was immediately added to Slitheris. Not only will it show vulnerability status without credentials, it also detects if the computer is infected with WannaCry/NotPetya. In addition, this feature has the added value of also determining if SMBv1 and SMBv2 is enabled, as some may want to disable SMBv1 due to security concerns or verify either protocol is independently active.

Find Unpingable Devices

Slitheris uses the ARP Cache to find ‘stealth’ devices unresponsive to pings. These unpingable network devices are indicated with a ruby icon to indicate ‘hidden gems’ were found. Due to how IPv4 works, as long as ARP is being used on a network, all devices will be found.

Easy Web GUI Access

See which devices have web GUI’s and access them instantly in your favorite web browser by simply clicking on the IP address. Both HTTP and HTTPS web GUI’s are detected, indicated by a world icon for HTTP and a lock icon for HTTPS. Secure (HTTPS) GUI’s on devices with both HTTP and HTTPS pages can be accessed by right-clicking on the IP address.

Portable Mode Feature

Especially requested by MSPs, you can now create a portable version of Slitheris Network Discovery, usable from any PC with a local administrator account.

This is only the beginning! Much more to come!
