Gear Percival Actually Recommends
Stuff worth plugging in
Every tool on this site is free. This page is different — it's a shortlist of network and security gear, with affiliate links attached.
The Honest Disclosure
"Quick and upfront: the links on this page are affiliate links. If you buy something through one, I get a small commission — you pay the exact same price either way. I only link to gear I'd actually tell a friend to buy, never just whatever pays the most."
"Why bother with this instead of just asking for donations? Because it doesn't cost you anything extra — the commission comes out of the retailer's cut, not your wallet. If you were already going to buy a cable or a switch, doing it through one of these links is a free way to help keep the toolkit running."
Not in the market for gear right now? You can support the toolkit directly instead.
