What we publish
Clear writing on networks & security
ProxyPortals is an independent English-language blog. We explain cybersecurity, computer networking, internet protocols, cloud infrastructure, and digital privacy in plain language — for students, homelabbers, and people who run systems at work.
Topics we cover
Every article is meant to be useful: definitions you can remember, diagrams in words, and the “why it matters” that textbooks often skip.
Cybersecurity
Threat models, authentication, malware basics, secure configurations, and how attackers actually think — without fear-mongering or marketing fluff.
Networking
TCP/IP, DNS, routing, switching, firewalls, NAT, VPNs, and how packets move from your laptop to a server on the other side of the world.
Cloud & privacy
How modern infrastructure is built, what encryption actually protects, and practical habits for staying safer on the public internet.
How we write
Networking and security are full of jargon. We start from first principles and build up, so you can follow even if you are new to the topic.

Why ProxyPortals exists
Most people meet networking and security as a wall of acronyms: TLS, BGP, Zero Trust, MFA. The ideas behind them are not mysterious — they are just rarely explained without assuming a computer-science degree.
We started this site to publish long-form guides you can actually finish. Expect explainers on how the internet is wired, how encryption sessions work, how firewalls decide, and how to think about risk on a home network or a small company LAN.
We do not operate a public proxy, VPN, or scanning service from this website. ProxyPortals is a publishing site. Use what you learn on systems you own or are authorized to administer.
