BorderLock

A consumer app for business travelers, journalists, and activists crossing borders in high-risk regions that locks sensitive memory regions before shutdown and verifies no residual data on next boot.

Target user

Business travelers, journalists, and human-rights workers crossing borders where device seizure is a real risk

Features
  • One-click 'cross-border mode' that triggers a memory scrub and forces a full shutdown with verified cold-boot state
  • Pre-trip checklist that reminds the user to remove tokens, rotate credentials, and back up to encrypted cloud
  • After-border 'clean boot' diagnostic that confirms no unexpected memory persistence from the prior session
  • Optional secure travel pouch (faraday + cooling) for sale as hardware bundle
Why now

A widely-shared bare-metal RAM dumping tool on GitHub means the bar to performing cold-boot attacks has dropped from nation-state to individual, raising the stakes for anyone whose laptop may be seized.

Demand

CBP reports <0.01% of arriving international travelers had devices searched in FY2025; the real-world addressable set of journalists/activists/business travelers who both face seizure risk AND would pay for a consumer app is tiny.Border Search of Electronic Devices at Ports of EntryA Journalist Security Checklist: Preparing Devices for Travel Through a U.S. Port of Entry

Built-in OS pre-boot auth (BitLocker + TPM+PIN, FileVault) plus hardware mitigations like Intel TME already defeat the cold-boot threat at the disk-encryption layer; EFF and Freedom of the Press publish free checklists, leaving a narrow, commoditized gap.Intel Total Memory Encryption White PaperCold boot attack - WikipediaPreparing devices for travel through a US border - freedom.press

Monetization
3/10

Primary alternatives are free (EFF guides, OS-native FDE) and target users are price-sensitive activists/journalists; corporations route this through IT/MDM, not $50 consumer subscriptions.A Journalist Security ChecklistBorder Searches | Electronic Frontier Foundation

Longevity
5/10

Cold-boot risk is a decade-plus stable concern, but the trajectory favors hardware-side fixes (TME, AMD SME, DDR5 on-die ECC) shrinking the residual problem rather than expanding it.Frozen Secrets: Cold Boot Attacks Unlock RAM's Hidden DataIntel Total Memory Encryption White Paper

Feasibility
3/10

Reliably wiping/verifying RAM contents across shutdown requires kernel/driver work, hardware-specific knowledge of memory topology, and survives poorly against DMA/Thunderbolt-class attacks that bypass it anyway.What is a Cold Boot Attack and how can you stay safe?Physical Access Cyberattacks: How Can You Protect Yourself?
