Snail mail
Companies, especially those working with security services, are often targets for mail theft, fraud, and attempted breaches.
We strive to use secure electronic communication and avoid snail mail unless absolutely necessary.
If electronic means do not meet your needs and you still want to send us snail mail — let us know in advance via email or Telegram, and we will send instructions on how to proceed. When we have to, we use recommended, certified, or registered mail with restricted delivery, authentication, ID, and signature.
Important: If you decide to send regular mail with or without prior notice, consider the shipment lost if confirmation of receipt is not received.
