Threat, Vulnerability and Risk Assessment (TVRA)

Know your real threats, your weak points and what to fix first.

What we review The people, property, information and operations you need to protect, the threats against them, and how your current security, including physical security, could be defeated.

What you get Decision-ready findings in plain language, a ranked list of risks, countermeasures from low-cost fixes to larger investments, a confidential written report, and a briefing to leadership. Every threat, vulnerability and risk assessment (TVRA) follows a structured method aligned with the ASIS Security Risk Assessment Standard (ASIS SRA-2024) and ISO 31000:2018.
  1. Establish context and assets.
  2. Threat assessment.
