Key takeaways
- A risk assessment template gives security and GRC teams one place to list assets, score threats, and assign mitigations with owners.
- The workbook includes a 5x5 risk matrix, a 15-entry threat library, and formulas for inherent and residual risk.
- Review the register at least annually or after major architecture, vendor, or product changes.
- SecureSlate helps connect risk outputs to controls, evidence, and audit exports.
Overview
A formal risk assessment is how SaaS teams prove they identify threats, prioritize them, and track remediation. Auditors and enterprise customers commonly ask for a living risk register, not a one-time spreadsheet from audit season.
This template follows practices from ISO 27005 and NIST SP 800-30 and is ready to adapt to SOC 2, ISO 27001, and customer security reviews.
What makes it useful
- Structured scoring: Likelihood (1 to 5) x Impact (1 to 5) with Low, Medium, and High bands.
- Threat library: Starter scenarios for insider threats, ransomware, phishing, misconfigurations, and more.
- Residual risk tracking: Document controls in place, then re-score after mitigations.
- Ownership: Every row has an asset owner, risk owner, and due date.

Tab-by-tab walkthrough
Overview and Version & Approval
Set organization name, document owner, version history, and sign-off. This is what makes the file credible in audits.
Instructions
Six-step workflow: list assets, map threats, score L x I, classify using the matrix, document mitigations, and schedule reviews.
Risk Register
Core working tab. Columns include Asset ID, Threat ID, Likelihood, Impact, Inherent Risk Score, Current Controls, Mitigation Plan, Residual Risk, Owner, and Due Date. Replace sample rows with your production systems, customer data stores, and key SaaS tools.
Threat Library
Reference list of 15 common threats with categories and attack vectors. Link Threat IDs from the register to keep assessments consistent across teams.
Risk Matrix
Color-coded 5x5 grid for Likelihood x Impact. Use it in workshops so security, engineering, and leadership agree on risk bands.
How to use it as audit evidence
| What auditors look for | Where it lives in the template |
|---|---|
| Formal risk process | Instructions + completed Risk Register |
| Scoring methodology | Risk Matrix + Likelihood/Impact columns |
| Ownership and remediation | Owner, Due Date, Mitigation Plan columns |
| Review cadence | Version & Approval + dated version history |
Store exports in your evidence library after each quarterly or annual review.
Common mistakes
- Scoring every risk as Medium to avoid hard conversations
- No link between risks and actual controls or tickets
- Register not updated after new vendors, regions, or product launches
- Threat library ignored, leading to inconsistent descriptions row to row
How SecureSlate helps
SecureSlate maps risks to controls, tracks evidence freshness, and exports audit-ready packages so your register stays connected to what you actually operate.
FAQ
How often should we update the risk register?
Many SaaS teams review quarterly and after significant changes (new product surface, major vendor, acquisition, or breach).
Does this replace a full ISO 27005 assessment?
No. It is a practical workbook. Scope and depth still depend on your environment and auditor expectations.
Who should own the register?
Typically security or GRC, with asset owners in engineering and business units validating rows for their systems.
