Sole proprietor, FIFO Networks
Cybersecurity - Networks - Wireless – Telecom - VoIP
Most of my money comes from contract work for public utilities around the country, but I also provide remote tech support to small business and SOHO clients, mainly (but not exclusively) in the USA.

I do a fair amount of custom work for people when a loved one dies: unlocking computers, data recovery, and account recovery (Advice: keep paying their cell phone bill until you've got all their data back).

Also, personal cybersecurity for journalists, TV reporters, politicians down to the City Council level, and political candidates. TV stations: contact me for contract pricing for your entire news team.

Use https://fifonetworks.com/contact-us/ for questions or to schedule service. It's just me. You'll be communicating directly with me.

Information security stuff with emphasis on payment security. Views expressed are my own.

I'm a hacker and mainly post about web security.

By profession, I am a pentester and team leader @usdAG.

I like to explain and understand things and I am convinced that the two go hand in hand.
So my posts are mostly of an educational nature.

Lately, I spend most of my free time developing CVE Crowd.

Professional paranoid. Toots mine, not employers past/present/future. RT/boosts ≠ agreement. E pluribus unum.

Trying to use @bsy for "social", @bsy for math/CS, and @bsy for security news, but we'll see if it's workable.
