Congrats on an incredibly impressive and technically complex product.

Operating such high visibility events like the Olympics sounds pretty nerve-wracking. How much of an issue is security for you? Do you experience any attacks?

Security has been a hot topic for the past few years, but it's getting even more attention now. Fortunately, it’s mostly a concern for production facilities, and the most effective solution is often complete isolation—most production networks don’t have internet access at all.

With the rise of remote production (where the control room is located at headquarters while cameras and microphones are on-site at stadiums), broadcasters are implementing VPNs, private fiber connections, and other methods to stay largely separate from the public internet.

In our case, the only part that uses the public internet is the relay server, which is necessary when working over cellular networks. Security is one of the main reasons we haven’t expanded this service into a full cloud portal yet—it’s much easier to secure a lightweight data relay with no database, running on a single port, than to lock down a larger, more complex system.

I want to add that the relay server is never handling any customer secrets (so a low value target), and we have techniques in place to reduce the probability of DoS (increase the cost to the attacker).

So even if someone would be able to break into the server through the small attack surface, he would not be able to change any setting on any of our customer's devices. Or even read any status either. Of course, if someone can break into our server, the DoS is inevitable, but so far this never happened.
