Device hardening
Making the everyday phones and computers you already carry as private and resilient as they can be.
Protective security
Quiet protection for people who matter.
ArtemSec helps high-profile individuals secure the phones, computers, networks and accounts they already rely on against surveillance and attack. Clear guidance, hands-on hardening, and purpose-built tools where off-the-shelf falls short. You keep the keys. Nothing phones home.
Capabilities
Defense across every surface.
Your exposure spans phones, laptops, home networks, accounts and the places you move through. Most of it can be made far safer with the gear you already own.
Network defense
Segmented, filtered home and travel networks with encrypted tunnels and nothing exposed that doesn't need to be.
Private infrastructure
Self-hosted services and storage under your control, so your data never has to live on someone else's servers.
Advice & threat modeling
Straight recommendations based on who might take an interest in you, and how you actually live and travel.
Incident response
Fast triage, containment and recovery when something looks wrong, with the lessons built back into your defenses.
Custom solutions
Purpose-built tools and configurations, researched and tested in-house, when off-the-shelf products can't meet the need.
Approach
Built, tested, yours.
We work alongside you, so you understand what changed and why, and the protection holds when we're not in the room.
Assess
Look at your devices, networks, accounts and routines, and work out the realistic threats.
Harden
Lock down what you already own, step by step, adding custom tools only where they're needed.
Hand over
You hold the keys. Everything is documented, and no access is left behind unless you ask for it.
Evolve
Revisit and test the defenses as threats and devices change, and respond when something looks wrong.
Principles
Discretion is the product.
The people we protect value privacy as much as security. Everything we do is designed to stay out of sight.
- Your keys, your dataEncryption keys and credentials stay with you. Your data is sovereign.
- No backdoorsNo remote access, telemetry or tracking added to anything we touch.
- ConfidentialPrincipals, locations and details are never disclosed.
- Engineered, not improvisedEvery defense is documented, reproducible and tested before it is trusted.
