Web Application Whitelisting

On this page:


The DekkoSecure web platform requires whitelisting in corporate network/device environments where strict firewall and filtering systems may be in operation. The whitelisting policies detailed below are required to allow the platform to be accessed and perform reliably.


  • Whitelist all subdomains of DekkoSecure (*
  • Open TCP 443 (HTTPS) and allow UDP 10000-20000 (SRTP) for * (specifically required for DekkoSecure Meetings)

Browser Policies


  • Allow
  • Allow [*.]

Pop-ups (for AAD SSO windows):

  • Allow

What is SRTP traffic used for?

SRTP is utilised for the DekkoSecure for Government and Law Enforcement video conferencing feature, which is built using the WebRTC ‘insertable streams’ API.



For service reliability, the DekkoSecure platform uses load balancers which comprise of multiple bridges, which change dynamically, so a single subdomain cannot be defined; therefore * is specified.


Can you provide a single/static IP address for whitelisting?

For infrastructure failover and DDoS protection, DekkoSecure platform’s IP is not static and changes over the time, so we cannot provide a single IP. The IP range for the platform is over 100k addresses.
