About Us

Ian Zatman founded SNG Security Ltd in 2017 to deliver privacy and security that email cannot provide. SecurityNet is a simple to use encrypted data transfer service for a global audience of users where each user passes information directly to another user.

By directly we mean that literally.  

  • Your data flows from your computer to your contact's computer.  
  • No cloud or server or middle-man in between you and your client. 
  • No opportunity for spies, hackers, governments to get at your data. 
  • Encrypted end to end with ever changing passwords.
  • And even if they do intercept a transmission, all they get is garbage!

SecurityNet: When email and cloud storage is just not secure enough.

Exchange confidential data with colleagues, clients, customers.

Eliminate your exposure to risk easily and conveniently.

How do we do this?

  • Firstly, we don't store your data  - unlike the big boys of this world!  
  • We connect you to your invitation-only contact just while your files are being transmitted.
  • We never touch your data, other than to transmit files from you direct to your contact.
  • The encryption passwords change every few seconds - even we don't know them.
  • Only you and your invitation-only contacts get to see your confidential files.
  • There is no cloud storage, no middle-man, no tracking, and no logging. 
  • Your business really is YOUR business.

SecurityNet installs in minutes, and users can grow a completely private encrypted user network from a couple of users to hundreds.

For those times when email and cloud storage is just not secure enough for your private files, we provide you with your own Private Encrypted User Network to effectively eliminate your exposure to risk, easily and conveniently.

The story behind SecurityNet

Ian has been an IT consultant for more years than he wishes to think about!

​On one assignment he designed security software for a major European Bank to secure and encrypt the transmission of payments instructions across insecure networks throughout Eastern Europe.

This was initially used in the bank's Regional Wholesale Banking Operations and then spread to the Payments & Cash Management department for wider use.

Originally called Security Blanket, the software required the resources of a major bank's IT department to install and maintain.


Then, around 2015, Ian ​decided to build a security service that secures and encrypts confidential data as it travels across the internet. This service would - and should - be made available to anyone, be it an enterprise, a smaller business or even individuals.

Advances in technology enabled us to finally succeed in producing a plug-and-play Security and Privacy system for any business to communicate and exchange confidential data with its clients.

And so was born...

SecurityNet:  For Privacy & Security that email cannot provide.

Where each computer ​passes information directly to another.

No tracking - No logging - No snooping - No insecure "cloud".

In 2017 Ian founded SNG Security Ltd to provide the SecurityNet Service.
