How to Create a Security Review Checklist in Notion
Security reviews fail not because engineers are careless but because there is no systematic checkpoint. A security checklist embedded in your engineering workflow ensures that every feature with security implications gets reviewed consistently — regardless of who built it or who reviewed the PR.
This guide covers how to build a security review checklist in Notion that integrates into your engineering process: structured checklist databases, threat modeling templates, and a sign-off workflow that creates an audit trail.
Step-by-step guide
Define the security review trigger criteria
Before building the Notion system, agree on when a security review is required: any change that touches authentication or authorization logic, any new data storage (especially PII or financial data), any change to API endpoints that accept unauthenticated input, any new third-party integration, any change to cryptographic functions, and any new file upload or user-generated content handling. Document these criteria in a Notion page called "When Security Review Is Required" and link it from your PR template.
Create the Security Reviews database
Create a Notion database called "Security Reviews" with properties: Feature (title), Status (select: In Review, Approved, Approved with Conditions, Rejected), Engineer (person), Reviewer (person — the security-focused engineer or external reviewer), Review Date (date), Feature Type (multi-select: Auth, Data Storage, API, Third-Party, Crypto, File Upload), Risk Level (select: Critical, High, Medium), and Linked Ticket (URL — Jira or Linear ticket URL). Each feature requiring security review gets one database entry.
Build the security review checklist template
Create a database template called "Security Review." Template sections: Feature Description (one paragraph on what the feature does and what data it touches), Threat Model (table with columns: Threat, Attack Vector, Likelihood, Impact, Mitigation), OWASP Checklist (checkboxes organized by OWASP Top 10 category: A01 Broken Access Control — list of checks, A02 Cryptographic Failures — list of checks, A03 Injection — list of checks, continuing through A10), Data Flow Diagram (embedded Figma or Excalidraw showing data movement), Findings (table: Finding, Severity, Recommendation, Status), and Sign-off section (checkboxes for engineer and reviewer with date).
Populate the OWASP checklist items
For each OWASP category, add specific checkbox items relevant to your stack. A01 Broken Access Control: authorization checked on every API endpoint, direct object reference uses random IDs not sequential, admin functions restricted by role not just UI, API endpoints tested with valid tokens of lower-privilege users. A02 Cryptographic Failures: passwords hashed with bcrypt or Argon2, no sensitive data in URLs or logs, TLS required on all external connections, secrets stored in environment variables not source code. Tailor these items to your specific stack — a Node.js API has different items than a mobile app.
Create the sign-off and audit trail workflow
In the Security Reviews database, the sign-off workflow is: engineer completes the checklist and sets Status to "In Review," reviewer is @mentioned in a Notion comment on the review page, reviewer goes through the checklist and findings, reviewer adds their sign-off checkboxes (date + digital signature in the comments), and reviewer updates Status to "Approved," "Approved with Conditions," or "Rejected." Conditions must be resolved before the feature ships. All comments, sign-offs, and status changes are captured in Notion's audit history. Export the review page as PDF before shipping for the security audit record.
Common mistakes
A generic checklist that applies to nothing specifically
A security checklist with "check for SQL injection" is not useful to an engineer using an ORM. Tailor checklist items to your actual stack: "verify Drizzle ORM parameterization is used on all queries — no raw SQL interpolation of user input." Specific, actionable items get checked. Generic items get rubber-stamped.
Security review as a post-PR gate
A security review that happens after the code is written is a late-stage quality check that catches problems expensively. Move security review earlier: the checklist should be filled in during design and PR creation, not after merge. A threat model written before implementation prevents architectural mistakes that are expensive to fix.
No tracking of approved-with-conditions reviews
Approvals with conditions ("approved, fix the logging of tokens before shipping") create a gap: the condition must be resolved but there is no tracking mechanism. In the Security Reviews database, create a "Conditions" section in the review template with a checkbox list of required fixes. The feature is not eligible to ship until all condition checkboxes are checked by both the engineer and reviewer.
Tips
Add a "Security Review Required?" checkbox to your Jira or Linear ticket template with a link to the trigger criteria — this makes the security review decision visible at ticket creation rather than at PR time
Create a Notion template for a "Lightweight Security Review" for medium-risk features — a 10-item checklist for features that touch existing authenticated paths without introducing new data storage. This reduces the friction for medium-risk reviews and prevents teams from skipping reviews because the full checklist feels too heavy
Export the Security Reviews database as a CSV quarterly and review the distribution of Risk Levels — a team that consistently reviews only "Medium" risk features and never "Critical" has a risk assessment calibration problem, not a security process problem
How Vantage helps
Security reviews are a gate in the engineering process that PMs often forget to budget for. When Vantage generates requirements and tickets for a new feature, it flags which requirements trigger a security review based on the feature type — so the sprint plan includes the review time rather than discovering it as a surprise blocker at PR merge.
