Where Traditional Models Break Down

Most threat modeling frameworks were designed for reversible systems. They assume:

• Transactions can be rolled back
• Accounts can be frozen
• Admins are trusted
• Providers are always available
• Mistakes are survivable

The reality in high-risk systems:

• Cryptographic keys represent ownership
• Transactions are final
• A single admin action can be existential
• Security tooling becomes a dependency
• Insider risk and pressure are real

In these systems, failure is not an outage. It is permanent loss.

Ideal for:

System architecture review
Trust boundary analysis
Identity and access control assessment
Transaction and payment flow analysis
Threat modeling and risk assessment
Mitigation and remediation roadmap

Architecture First. Authority First.

BitVault Advisory models power before attacks.

Architecture review is important, and it is linked to a good threat model. But digging deeper — for a higher quality assessment — processes must be evaluated too.

We specialize in mission critical assessments. Delivering a unified view of risks and applicable controls for mission critical systems.

In high-risk systems, security fails when one actor can act alone, instantly, and invisibly.
