Startup / Small — Post S2 (IGA)
Focus: Building lightweight governance habits—reviews, documentation, and accountability—without enterprise IGA tools.
Previous: Post S1 covered IAM setup (MFA, JML, SSO, and offboarding).
TL;DR
Startups don’t need full-blown IGA systems to practice governance.
You just need a repeatable rhythm—review who has access, record it, and act on changes.
With nothing more than spreadsheets, automation tools, and discipline, you can meet audit, investor, or SOC 2 expectations while staying lightweight and affordable.
1. What “lightweight governance” really means
Identity Governance & Administration (IGA) sounds heavy, but at its core, it’s about three simple questions:
- Who has access?
- Should they still have it?
- Can we prove we checked?
For startups, the right approach isn’t buying a complex IGA suite. It’s starting a review cadence that’s traceable and easy to automate later.
2. Why small orgs should care early
Governance matters even before compliance does:
- Reduces breach risk: shared admin accounts, unused licenses, and stale credentials are silent liabilities.
- Builds investor trust: early-stage due diligence often includes “How do you manage user access?”
- Prepares for SOC 2 or ISO 27001: access reviews and offboarding evidence are standard control points.
Early habits save huge remediation costs later.
3. Start simple: The lightweight review loop
You can run a working governance loop in three steps, using free or near-free tools:
Step 1: Export who has access
Use whatever system you have:
- Microsoft Entra / AD:
Get-ADUser -Filter * -Properties memberOf | Export-CSV users.csv - Google Workspace: Admin console → Users → Export
- Okta Free Tier: Reports → User Apps → Export CSV
- SaaS apps: Slack, GitHub, and Drive all offer user exports (CSV or API)
Dump all results into a single spreadsheet (Access_Register.xlsx).
Step 2: Ask “should they still have it?”
- Create a simple review template in Excel or Google Sheets:
App User Role Manager Last Login Keep (Y/N) Notes - Send each manager their tab or filtered view.
- They mark “Keep = Y/N” and add comments (contract ended, role changed, etc.).
- Even Google Forms or Microsoft Forms can work to collect responses.
Step 3: Track and act
- Centralize all results in one sheet:
Access_Review_YYYY_Q#.xlsx. - For “Remove” items:
- Disable account in AD, Entra, or Workspace.
- Log date/time and “action taken by” in a simple audit sheet.
- Store all quarterly review files in
/Governance/Reviews/.
These become your evidence for SOC 2, ISO 27001, or cyber insurance.
4. Add light automation (optional but powerful)
When the process is stable, use no-code / low-code tools to automate notifications and evidence tracking:
| Tool | Purpose | Example |
|---|---|---|
| Microsoft Power Automate / PowerShell | Email reviewers CSVs, collect responses | Send “Access Review” task to each manager quarterly |
| Google Apps Script | Automate sheet merges | Combine manager tabs into a master |
| n8n / Zapier | Workflow orchestration | Trigger offboarding tasks when “Keep=N” |
| Adaxes | Enforce changes in AD/Entra | Auto-disable accounts after manager approval |
| Linx IGA | Optional add-on | Adds dashboards and audit evidence for small teams |
Even without these, manual + predictable beats automated chaos.
5. Frequency & roles
| Frequency | Review Type | Owner |
|---|---|---|
| Quarterly | Manager review of app access | Department leads |
| Semiannual | Admin review of privileged accounts | IT or Security |
| Annual | Audit summary + evidence export | CEO/CTO signoff |
Add calendar reminders or automate in Teams/Slack:
“Quarterly Access Review due by Friday — confirm or remove access in your sheet.”
6. Minimal evidence checklist
You can satisfy early-stage governance with these five files:
/Access_Review_Qx_YYYY.xlsx— final manager approvals/Offboarding_Log.csv— terminations with disable dates/MFA_Report.csv— MFA status from Entra/Workspace/Privileged_Access_List.csv— who has admin rights/Policies/Access_Control_Policy.docx— 1–2 pages max
Keep them under version control (GitHub private repo, Google Drive, or SharePoint). That’s your lightweight audit trail.
7. Compliance tie-ins (NIST CSF 2.0 & SOC 2)
Even a manual process maps neatly to real frameworks:
| Control Area | Example | Mapping |
|---|---|---|
| PR.AC-1 / PR.AC-4 (NIST CSF) | Maintain and review authorized users | Spreadsheet + manager attestations |
| SOC 2 CC6.3 / CC6.6 | Periodic review of user access | Quarterly reviews + logs |
| ISO 27001 A.9.2.5 | Review of user access rights | Annual audit package |
| Zero Trust Principle | Verify continuously | Reviews + removal confirmation |
8. Evolve gradually
Your first goal isn’t perfect governance—it’s a habit of visibility and correction.
When reviews feel repeatable:
- Move to automated evidence collection with Linx or Adaxes.
- Integrate HR API triggers for joiner/leaver workflows.
- Add dashboard visibility (Power BI, Looker, or Linx Analytics).
That’s your runway to mature governance without buying a heavy platform.
9. What “good” looks like (KPIs)
- Access review completion: ≥ 95% per quarter
- Offboarding SLA: ≤ 1 day from HR term
- Dormant accounts: < 2% of total users
- Evidence folder updated: Quarterly, no gaps
- MFA coverage: ≥ 98%
If you can hit these with a spreadsheet and a cron job, you’re winning.
10. Quick checklist
✅ MFA report current
✅ Shared accounts removed
✅ Access register up to date
✅ Reviews logged
✅ Offboardings documented
Print it. Tape it. Make it a habit.
