Cyber risk modeling for private equity
OVERVIEW
Make every cyber insurance decision with your own numbers
Turn cyber insurance from a cost you justify into a decision backed by evidence. CyberCube brings the cyber risk quantification the insurance market already relies on to private equity, so you can benchmark limits and retentions against peers, see what one technology failure would cost the fund, and back every decision with your own numbers.
Clarity on every company’s exposure
Understand each company’s exposure and how peers transfer risk, so you and your broker can set limits and retentions on evidence, not guesswork.
Smarter risk transfer, stronger returns
Compare insurance structures side by side and choose the one that maximizes return on investment and meets each portfolio company’s objectives
Protect fund returns from shared technology risk
Solutions
Two ways to take control of cyber insurance spend
Expert-led analysis, ready for your next decision. No platform to learn and no questionnaires for portfolio companies.
Insurance Purchasing Insights
For a single portfolio company or acquisition target, before diligence, at close or ahead of renewal.
- A loss curve showing what a cyber event could cost the company, from an average year to a severe one
- Peer benchmarking of both limits and retentions, against genuine peers
- Average Annual Loss and total cost of risk (premium plus uninsured loss), to put insurance spend in context
- An independent baseline to take into the broker conversation, delivered within days and briefed by CyberCube experts
Portfolio Aggregation & Program Structuring
For the whole portfolio, typically as an annual readout.
- Catastrophe and attritional modeling of economic, insured and uninsured loss across every portfolio company
- Gap analysis showing how much uninsured loss comes from limit exhaustion, retentions and waiting periods, and which companies drive it
- Alternative program modeling, from targeted limit increases to a portfolio-wide excess layer, compared on uninsured loss and payback

How it works: start with one company, scale across the portfolio
- Prove it on a live deal or renewal. A low-cost proof of concept on one or two companies, so you see the value on a decision you're already making.
- Expand in tranches. A 12-month engagement covering groups of portfolio companies, with pre-agreed pricing as deal flow grows.
- Readout and review. Reports on targets and renewals as they come up, and an annual portfolio aggregation readout briefed by CyberCube experts.
We work through insurance brokers or directly with PE firms, whichever you prefer. Engagements can run with counsel involved where required.
Built for the people who buy and advise on cyber insurance across a portfolio
From the operating partner who owns insurance spend to the broker who places the program, CyberCube gives everyone around a private equity portfolio the same independent view of cyber risk.
-
You own insurance spend across the portfolio, and you think in benchmarks. CyberCube gives you a carrier-independent view of each company's cyber exposure and what genuine peers buy, so you can buy with confidence, test options with your broker, or get more coverage for the same premium. Across the fund, you see what a bad cyber year would cost and how much is uninsured.
- Limit and retention benchmarking against true peers
- Total cost of risk for every company you model
- A defensible, documented basis for each insurance decision
- Fast reports on targets and on larger portfolio companies ahead of renewal
-
Every PE pitch sounds the same. CyberCube turns your expertise into something a PE firm can see: the portfolio's insured and uninsured exposure, where the gaps sit, and which program change closes them most efficiently. It opens conversations about the portfolio companies you don't yet place, and builds on the Broking Manager analysis your team already runs.
- Portfolio aggregation modeling that CyberCube runs and briefs for you
- Client-ready outputs you can present as your own advisory
- Fixed scope priced by number of PE clients, simple to bundle into diligence or advisory fees
-
Traditional cyber diligence can be intrusive, slow and expensive for the decision it informs. CyberCube gives deal teams a fast, outside-in view of a target's cyber exposure in insurance terms, so you can set limits at close and see which deals warrant deeper forensic work.
- Loss curve and peer benchmark for the target
- Insurance terms the target's CFO and broker can act on

Frequently Asked Questions (FAQs)
-
CyberCube helps private equity firms and their brokers answer this by modeling a portfolio company's potential cyber losses, from an average year to a severe one, and benchmarking its limits and retentions against genuine peers, so the firm can see whether the cover it buys is proportionate to the company's actual exposure. The answer depends on the company's own loss profile and the firm's appetite for uninsured loss, advised by the broker.
-
Cyber risk quantification for private equity expresses the cyber risk of portfolio companies and acquisition targets in financial terms, and CyberCube's version is built on the same cyber catastrophe and loss models that most leading cyber brokers, insurers and reinsurers already use to price and manage cyber risk. That means outputs come in the terms insurance is bought in (limits, retentions, Average Annual Loss and total cost of risk) and carry weight in the broker and underwriter conversation.
-
CyberCube quantifies cyber risk across a private equity portfolio by modeling every portfolio company's economic, insured and uninsured losses and providing the losses expected in an average year to unlikely but extreme years. Firms use the results to decide where to raise limits, adjust retentions or consider a portfolio-wide program.
-
Cyber aggregation risk is the chance that one event, such as an outage at a cloud, software or healthcare records provider that several portfolio companies rely on, hits many of them at once. CyberCube models that technology concentration so private equity firms can see what such an event would cost the fund and how much is insured.
-
CyberCube's analytics are used by the majority of the cyber insurance industry by premium, including 85% of the top global cyber brokers. This creates a rich data feedback loop to help organizations benchmark their cyber insurance coverage against limits.
-
CyberCube gives private equity deal teams a fast, outside-in view of an acquisition target's cyber exposure, expressed in insurance terms rather than technical findings, using little more than the company's name and its proposed insurance terms, so the firm can inform limits at close and identify which targets warrant deeper forensic diligence before the deal closes.
-
Security ratings score how well a company appears to be protected, while CyberCube's cyber loss modeling estimates what a cyber event would cost a portfolio company or the whole fund in dollars and how much of that loss is insured. The two answer different questions, so many firms use ratings alongside CyberCube rather than instead of it.
-
Yes: CyberCube does not sell insurance, so its analysis gives private equity firms a carrier-independent view of cyber risk that is not bundled with any insurer's coverage and can be taken to any broker or market, while still being built on the models that brokers, insurers and reinsurers already trust. We can deliver through your broker or work with you directly.
-
CyberCube treats private equity firm and portfolio company information as confidential, works within the confidentiality and data terms each firm requires, and can run engagements with a firm's legal counsel involved where privilege is needed, so sensitive deal and portfolio information stays protected throughout the engagement, from a single-company proof of concept to a full portfolio readout.
