Why Should Every Organization Have a Cyber Risk Register?
Last year a mid-sized logistics company in Ohio discovered they had been hacked for eight months. The attackers had full access to emails, customer data, and payment systems. When the board asked the IT manager, “How did this happen?” the honest answer was painful: “We didn’t know this risk even existed.” They had firewalls, antivirus, and backups, but no one had ever written down the fact that their freight management software still used a default admin password from 2018. A cyber risk register would have caught that in five minutes. It is not a fancy tool or expensive software. It is simply a living list of “things that can go wrong with technology and data, how likely they are, how bad they would be, and what we are doing about them.” Yet most organizations still don’t have one. In 2025, that is no longer optional. Regulators, insurers, customers, and boards now expect it. This post explains, in plain English, why every company (big or small) needs a cyber risk register and how to build one without hiring a consultant.

What Exactly Is a Cyber Risk Register?
A cyber risk register is a spreadsheet or document that answers four questions for every important risk:
- What can go wrong?
- How likely is it?
- How bad would it be?
- What are we doing (or planning to do) about it?
It is updated regularly and shared with leadership. That’s it. No magic, no secret sauce.
Why Your Organization Actually Needs One
- You can’t fix what you don’t know exists
- Boards and regulators now ask for it by name (SEC, DORA, NIS2)
- Cyber insurance applications require it (or premiums skyrocket)
- It stops the same conversation happening every year (“Didn’t we already fix phishing?”)
- It turns vague worry into concrete actions and budgets
- It proves you are doing something reasonable if you ever get breached
The Real Benefits (With Numbers)
- Companies with a maintained risk register reduce breach costs by 29% on average (Ponemon 2025)
- Insurance premiums drop 15–40% when you can show a mature register
- Audit time shrinks from weeks to days
- Leadership finally understands why you keep asking for budget
- Teams stop duplicating work on the same risks
A Simple Cyber Risk Register Example
| Risk ID | Risk Description | Likelihood | Impact | Risk Score | Current Controls | Action Plan | Owner |
|---|---|---|---|---|---|---|---|
| CR-001 | Ransomware via phishing email | High | Critical | Very High | Email filter, MFA | Add phishing-resistant MFA + quarterly training | CISO |
| CR-002 | Third-party vendor breach | Medium | High | High | Annual questionnaire | Implement continuous monitoring tool | Procurement |
| CR-003 | Unpatched legacy server | Low | Critical | Medium | Isolated network | Replace by Q4 2026 | Infrastructure |
How to Build One in 30 Days (Step by Step)
- Day 1–5: Gather the usual suspects (IT, legal, finance, operations) for a 2-hour workshop
- Day 6–10: List every asset that would hurt if lost (data, systems, reputation)
- Day 11–15: Brainstorm “what could go wrong” for each (no filtering yet)
- Day 16–20: Score likelihood and impact (use 1–5 scale, multiply for risk score)
- Day 21–25: Write down existing controls and planned actions
- Day 26–30: Present to leadership, get approval, schedule quarterly reviews
Common Mistakes That Make It Useless
- Treating it as a one-time project instead of a living document
- Only IT owns it (risk lives everywhere)
- 100+ risks with no prioritization
- No clear owner or deadline for actions
- Hiding it in a folder no one ever opens
Regulatory and Insurance Pressure in 2025
- SEC (US): Public companies must disclose material cyber risks and governance
- DORA (EU): Financial firms need formal risk registers by January 2025
- Cyber insurance: 70% of carriers now ask for a copy before quoting
- Board liability: Directors can be personally sued for “failure of oversight” without evidence of risk management
Conclusion
A cyber risk register is not glamorous. It will not stop bullets or win you awards. But it is the single best way to turn chaos into clarity. It forces conversations that should have happened years ago. It gives leadership a one-page view of what keeps you up at night. And when (not if) something goes wrong, it proves you were paying attention.
Every organization already has risks. The only question is whether you write them down and do something about them, or wait until they appear on the front page of the news.
Start your register this week. Your future self, your board, and your insurance broker will thank you.
What is a cyber risk register?
A living list of cyber risks, their likelihood, impact, and mitigation plans.
Is it the same as a risk assessment?
No. An assessment is a point-in-time exercise; the register is the ongoing home for those findings.
Do small companies need one?
Yes. A 10-row spreadsheet is better than nothing.
Can I use Excel?
Absolutely. Most companies start there.
Who should own the register?
The CISO or head of IT, but every department must contribute.
How often should we update it?
Quarterly at minimum, or after any major incident or change.
Does it replace cyber insurance?
No, but it makes insurance cheaper and claims easier.
What if we have 200 risks?
Focus on the top 20 by score. The rest can wait.
Is it a legal requirement?
Increasingly yes for regulated industries (finance, healthcare, public companies).
Can we outsource it?
You can get help, but ownership must stay internal.
Do tools like GRC platforms replace it?
They help manage it, but the register itself is the core idea.
Will the board actually read it?
Yes, if you give them a one-page heat map and the top 5 risks.
What if we miss a risk?
Better to have 90% documented than 0%. You improve over time.
Is it only for IT risks?
No. Include third-party, insider, physical, and compliance risks too.
How long does it take to create?
A basic usable version in 2–4 weeks with the right people in the room.
Does it help during a ransomware attack?
Yes. You already know your critical assets and recovery priorities.
Can it reduce our insurance premium?
Often 15–40% when you show a mature, reviewed register.
What if leadership ignores it?
Make the top 3 risks personal: revenue loss, regulatory fines, job loss.
Is a shared Google Sheet good enough?
For startups, yes. Add version history and access controls.
One sentence to convince my boss?
“If we get breached tomorrow, the first question from regulators and insurers will be: show us your risk register.”
