The highest-value security move costs nothing: an honest look at the gaps you already have. Our free Personal Opsec Checklist is a structured self-assessment across six areas: public records, digital footprint, personal space, routines, self-defense, and situational readiness. You rate your own risk in each, then prioritize what to work on first. A sample from our extended version, distributed exclusively at Gart Training sessions. Link:

What does the safety app on your phone know about you? Gart's answer: nothing. By design. 1. No background tracking. The alert button stays silent until you trigger it. No background location. 2. End-to-end encrypted. Alert content and chat use NIP-44. We can't read them, and neither can the relays. 3. Nothing to hand over. No identity, contacts, or location stored. You can't leak what was never collected. 4. Publicly verifiable. The live alert stream is public. We'd rather you check than trust us. We wrote exactly how it works. Full blog:

A Safety App That Can't Track You

Every other safety app keeps you safe by watching you. Gart keeps you safe by knowing nothing about you.

Join us this Wednesday for a free Gart webinar with @Max Hillebrand and the Sound Money Solutions team: Password Management & Access Control. Live session with a Q&A. Last week, at @BTC Prague we only scratched the surface of personal security. This is where we go deeper. Besides your password, what else stands between someone and your accounts? 10 seats left.

Why build another safety app? Because the popular ones watch you, sell you, or can be tricked into handing you over. One has 98 million users and sold their location to data brokers within 20 minutes of collecting it. Full story:

Around 9 in 10 people attacked for their crypto come back home. Our training teaches the choices that put you in that number. Session 4 of the Gart Training, Survive & Thrive, covers the first 60 seconds and the hours after: when to comply and when not to, staying composed enough to think, and the prepared moves that buy you time. If it happened, would your next move be a decision or a guess? This is the final session of the June 9 training in Prague, 2 days before @BTC Prague . Signups close tonight. 5 seats left.

Every protocol is a decision you make once, now, while you're calm, so you or your safe contacts don't have to make it later, under pressure, with the clock ticking. Session 3 of the Gart Training, Protocol Design, is where we help you build yours. Who gets contacted, in what order, what they do, and the codes that signal you're in trouble without tipping anyone off. June 9 in Prague, 2 days before @BTC Prague 15 seats available.

Good security works in layers. Avoidance, deterrence, detection, delay, response. Each layer an attacker has to get through costs them time and risk, and most look for someone easier first. Session 2 of the Gart Training, Get Hard to Get, is on building those layers, plus the 30-day opsec plan to put them in place. June 9 in Prague, 2 days before @BTC Prague 15 seats available.

Digital Security Series, Session 1. An Introduction to Gart's Remote Training.

You will leave with a clear understanding of what a privacy-focused device setup looks like, why each layer matters, and what the implementation path looks like if you decide to take it further. This is an introduction to Gart's Digital Security Remote Training, a one-on-one service that walks you through the full setup at your own pace. What you will learn - Why hardware choice matters before you install anything, and what to look for in a privacy-focused device - How operating system selection affects what data leaves your phone and who can access it - What profile separation is, and how it creates an absolute wall between your Bitcoin activity and your daily apps - How routing Bitcoin traffic through Tor changes what your internet provider can see - What a sustainable maintenance routine looks like, so your setup does not decay over time Sign up now, we have limited seats to keep it nice and cozy.

Tomorrow we run the VIP security briefing for @BTC Prague 2026. The briefing is one piece of our engagement. We're running the independent security audit for the conference, working with the organizers, the on-site security teams, and the speaker and VIP advisory tracks. If you're a VIP attending the conference, join us tomorrow. You should have an invitation link in your email. On the agenda: - The 2025-2026 crypto incident pattern - Pre-travel info discipline - Transport and crowd protocol in Prague's tourist zones - Daily check-ins, duress codes and information management - What to do if something goes wrong on the ground

If you're into sovereignty and personal freedom, you know it doesn't start with key ownership. It starts with your and your family's personal safety. It's a topic many think about but most don't know how to tackle. Spending one day in a Gart Training in Prague 9th June might help:

Tomorrow 2pm UTC join our webinar about physical security for bitcoiners. Not just for the publicly doxxed.

Personal Security Webinar

for bitcoin podcasters, influencers and public speakers

Threat Intelligence: We explore the current situation facing crypto holders, including emerging trends and real-world scenarios. Proactive Prevention: You've already been doxxed. Now what? We walk through the concrete steps you can take to improve your personal security posture before a situation escalates. Practical Security: Digital hardening, safe travel protocols, handling dirty contacts, and securing your home and family - the everyday practices that close the gaps attackers look for. Confident Response: Clear, effective protocols to protect yourself and your family in the rare event that something unexpected happens.

Gart is running an independent security audit for @BTC Prague, Europe's largest Bitcoin-only conference. Scope: a full audit of event security posture, plus a dedicated advisory track for speakers and VIP guests. We work directly with the organizing team and with the on-site security teams on the floor during the event. The audit covers every layer from the first checkpoint at the gate to the last car leaving the after-party: threat picture, access control, VIP flow, comms, incident protocols, escalation paths, rehearsals. Why this engagement exists: targeted attacks against publicly known crypto holders are no longer rare. Our dataset documents 75 physical attacks in 2025, climbing through 2026 (stats.gart.io). Conferences put many of the most publicly recognized, most doxxed figures in one venue, on a published schedule. That concentration is what makes the event work. It is also what creates a serious duty of care and BTC Prague completely owns it. We will not publish what we find or recommend. That, by design, is not something you share with the public.
