Guerilla Marketing in 2022 for my project

I'm looking for ideas to promote my new project, "The 2hO Network" (https://2ho.ca). 2hO means "To Home Office" - where most of us are working these days.

It's a Peer to Peer VPN which wraps a zero-config admin framework around WireGuard. It coordinates NAT hole punching etc.

I know there are others out there. But it's a big world and I know it will find a niche. I am hoping for a small business and work from home audience.

My question is not really about the product itself. But more about how to get the initial exposure it will need before any serious media outlets will be comfortable covering it.

As the service is mostly free, I am hoping not to put a lot of money behind marketing. At least not until it has established some kind of foothold.

I know PR is the secret to success in this type of venture. But are there any tricks to getting it out there initially. Essentially, the problem is going from zero to one.

Any and all advice is welcome.

Thanks
