If you have ever been asked to "provide a TRA" by a government procurement office or an enterprise vendor security team, you already know the term is common. What is less common is a clear explanation of what the document actually is, why someone wants it, and what producing one actually involves. This guide covers that in plain language.
What a threat and risk assessment is
A threat and risk assessment (TRA) is a formal document that identifies the threats facing a system, application, or organization, then rates each one by how likely it is to happen and how bad the consequences would be if it did. The output is usually a risk register: a list of threats, their likelihood and impact ratings, the resulting risk level, and the controls in place or recommended to bring that risk down to an acceptable level.
It is not a penetration test, and it is not the same as a vulnerability scan. A pen test tries to exploit weaknesses in a live system. A TRA is broader and more structural: it looks at the whole picture, including business processes, data flows, physical access, third-party dependencies, and people, not just technical vulnerabilities. Many TRAs draw on scan results and pen test findings as inputs, but the assessment itself is a risk analysis exercise, not a hands-on hacking exercise.
Who actually needs one
Three groups ask for TRAs most often in Canada.
- Government procurement. Federal, provincial, and municipal RFPs for systems handling sensitive or personal information frequently require a TRA before go-live, following frameworks like the Government of Canada's Harmonized TRA methodology or provincial equivalents.
- Enterprise vendor risk teams. If you sell software to a bank, insurer, or large enterprise, their vendor security review may ask for a current TRA covering the system that will touch their data, separate from any SOC 2 report you hold.
- Regulated organizations doing internal due diligence. Healthcare, finance, and critical infrastructure organizations often commission TRAs on their own initiative before launching a new system, migrating infrastructure, or acquiring a company.
If none of these apply to you today, a TRA may still be worth doing proactively. Deals stall when a buyer asks for a risk assessment you do not have and cannot produce quickly.
What the process involves
A properly scoped TRA generally moves through the same stages regardless of methodology:
- Scoping and asset identification. Define the system boundary: which applications, data stores, networks, and third parties are in scope. This step matters more than people expect. A TRA scoped too broadly takes months and produces a report nobody reads; scoped too narrowly, it misses the risk the buyer actually cares about.
- Threat identification. Catalogue realistic threats: external attackers, insider misuse, third-party compromise, data loss, service disruption, and so on, drawing on threat intelligence and the nature of the system.
- Vulnerability and control review. Assess what controls already exist and where gaps remain, often incorporating architecture review, configuration review, and prior scan or test results.
- Likelihood and impact rating. Each threat gets scored against a defined scale, typically low/medium/high or a numeric equivalent, resulting in an overall risk rating.
- Recommendations and reporting. The final document lists prioritized remediation recommendations tied to each significant risk, along with residual risk after proposed controls are applied.

Realistic timeline
Timelines vary with scope, but for a single application or system of moderate complexity, expect roughly two to four weeks from kickoff to final report: about a week for scoping and information gathering, one to two weeks for the assessment itself, and a few days for review and finalization. Larger scopes covering multiple systems, or organizations with limited internal documentation, run longer. If a vendor promises a TRA in a couple of days, ask what corners are being cut on scoping, because that is usually where quality is lost.
Common misconceptions
A few misunderstandings come up repeatedly with buyers who are asked for a TRA for the first time.
- "A TRA is the same as SOC 2." They overlap in some evidence but serve different purposes. SOC 2 is an attestation against a defined trust services criteria framework, produced by an accredited auditor. A TRA is a risk analysis document and does not require an auditor's opinion. Some buyers ask for both. If your business needs both compliance certification work and risk assessment, our compliance solutions page covers how these pieces fit together.
- "One TRA covers everything forever." Risk changes as systems change. Most procurement and vendor review processes expect a TRA to be refreshed on a set cadence, commonly annually, or after a material change to the system in scope.
- "A TRA is only for large enterprises." Small and mid-size companies get asked for TRAs constantly once they sell into government or regulated enterprise buyers. Company size does not exempt you from the requirement; the scope of the assessment can be sized to match your system.
- "It is purely a technical exercise." A significant part of a TRA is understanding business context: what the data is worth, what happens if the system goes down, who has access and why. Skipping this and jumping straight to a technical checklist produces a document that will not survive scrutiny from an experienced reviewer.
Getting started
If you have a TRA requirement on your desk with a deadline attached, the fastest path is to get the scope right before anything else. A short scoping call typically clarifies whether you need a full TRA, a lighter-weight risk review, or something else entirely.
