Confidential computing on a VPS
On an ordinary VPS the host can read your guest memory. What AMD SEV-SNP and Intel TDX change, what attestation proves, and how to check the server you have.
Tor Browser vs Tails vs Whonix
Tor Browser, Tails and Whonix isolate different things. Work out which one your threat model actually needs, and what each one cannot protect.
Is Tailscale secure? The trust model
Tailscale never holds the keys that encrypt your traffic. The real question is what a compromised coordination server or a stolen identity account can do.
Prompt injection against coding agents
A coding agent runs on text an attacker can write. Map the real injection surfaces on a server, then rank the defences that actually shrink the damage.
