SeattleLab is proud to announce that our latest release SL Secure is now available.

SL Secure builds on the highly successful SLNet product range, it adds a layer of security between the SLNet server and the wireless handheld devices whilst maintaining the features provided by SLNet.

SL Secure optimises the SSH protocol link between radio frequency devices and it works with Windows versions 2016 onward as well as enabling an unlimited number of users.

SeattleLab CTO Lorcan Kennedy said “SeattleLab are delighted to announce our latest release. With SL Secure, we feel we have the most secure SSH software to support your organisation from the ground up.

Kennedy spoke of the improved usability with data migration adding that “Our new release means migrating to the cloud has never been easier or more secure.”


Customizable Permissions
Users run in their own appropriate security context, with all their own permissions in place, just as if they had logged in from the main console. This completely preserves all Windows’ C2 security features. SL Secure can lock down terminals so they can only reach specific applications and be prevented from getting to a command prompt.
Secure Logon
It also ensures encryption of usernames and passwords for secure logon over the network.
Full SSH Support
Out of the box support for SSH.

Usability for End-User

High Performance
SL Secure communicates via Winsock Sockets to the terminals and via Pipes to SLCon and the Windows Console Applications. To minimise the impact on the CPU resources, the SLNet secure programs are heavily multi-threaded and asynchronous.
Improved Performance and Reliability
Can handle thousands of user connections with modest requirements. SSH sessions tend to be more robust than the equivalent Telnet session.
Terminal Emulation
Can be customised to meet any terminal emulation or application character needs, details of which are provided in the Installation, Configuration and Administration Guide.

Access to Window’s Common Command Shell
Users who SSH into SL Secure can have full access to Windows’ Common Command Shell. It is completely configurable by the administrator, who can choose to disable access to the Command Shell on a user-by-user basis.
Direct Access to Custom Applications
It offers you the power to define default custom applications for users as soon as they log in.
Terminal Sequences
Also provides ANSI terminal sequences (compatible with the VT-100 and VT-220) for cursor positioning and formatted screen handling. It supports colours, UTF-8 characters, Unicode characters and custom key sequences.
Can insert a record in the Windows event log every time a user connects or disconnects along with a record of what process the user executed and the resulting data and screens from that process.
Remote Administration
SL Secure can be administered locally or remotely.
For security purposes, SL Secure is licensed to specific servers. A license key tied to the server ensures you can track your SLNet Secure licenses and prevent unauthorized uses. Install SLNet on a target server, it activates temporarily and provides a license request file that you email to the SeattleLab license group. A license key file is generated and sent back to you.
