I can only really talk about the voting, because that's the piece that I've been involved in.
The way we built it, we know it is secure. Mr. Burton mentioned this a bit beforehand. We worked quite closely with our own cybersecurity team, but we also had the system verified by the National Cyber Security Centre. We had them look over the architecture of the system and point out any concerns they had for us to address. Their concerns, in the end, didn't turn out; the system architecture wasn't a concern for them at all. They were more worried about other things.
I'll give one example. We send out an SMS message to members telling them a division is taking place. When we started the process, we'd send out a URL link to the member hub system, saying, “A division has begun. Please cast your vote and click on this link.” They didn't like that because it encourages people to click on links in text, which is how bad cyber-actors get you to start clicking on things you shouldn't and start stealing your details. They asked us to change that, but it was the only really substantial thing they wanted evolved.
We had them review the system and write up a report, which was sent to our manager and director of the clerks of the House. Obviously no cyber-team is going to say a system is perfect, but they said they were not concerned about the risk of tampering with a vote or members' being spoofed or anything like that. We got that reassurance from a central government body, basically.
