Every business faces more cyber risks than it can address at once. Assessing cyber risk is how you decide which ones deserve attention and money first. You do not need to be a security specialist to start. You need a clear view of what the business depends on, an honest look at current controls and a simple way to compare one risk with another.
A good assessment answers three questions in business terms: what matters most to keep running, what could realistically go wrong with it and which improvements reduce the most risk for the effort involved. The output is a ranked list with owners and dates, not a pile of technical findings.
List the systems and data the business depends on: email, the accounting system, the line-of-business application, customer records, the phone system and file storage. For each one, ask how long it can be unavailable before the consequence becomes serious rather than annoying, and what happens if its data is exposed or altered. Owners usually know these answers but have never written them down.
Then trace what each system depends on. Billing depends on the practice management system, which depends on the internet connection, which may depend on a single router in a closet. Sort the results into three tiers: critical, important and deferrable. If everything is critical, nothing has been ranked.
Record the devices, servers, cloud services and applications in use, where sensitive data lives and who has access to it. Pay special attention to administrator accounts, shared logins, former employees and vendors with remote access. Gaps in this inventory are themselves a finding, because unknown systems are rarely protected well.
Focus on the threats that commonly affect businesses like yours rather than every possibility. For most small and midsize businesses, the list includes:
For each critical system and threat, note what already reduces the risk: multi-factor authentication, endpoint protection, email filtering, backups, training and monitoring. Be honest about how well each control works, and mark each one effective, partial or absent. Multi-factor authentication on email means little if several accounts are exempt, and a backup that has never been restored is not yet a proven control. Partial controls deserve the closest look, because they create confidence without full coverage.
Use a simple scale from one to five for each risk:
Multiply the two to rank risks. The scores do not need to be precise. They need to be consistent, so that the team agrees one risk is clearly more urgent than another. Judge impact in business terms, such as lost revenue, missed deliveries or regulatory exposure, rather than technical severity.
Put each risk on one line with its score, an owner and a review date. Then decide how to treat it:
The owner should be a person rather than a department, and the review date should be specific. The register becomes the plan and the record of what leadership knew and decided. Review it regularly and whenever the business changes significantly.
A self-assessment using this method is a good starting point and helps leadership understand the issues. A professional assessment adds technical review of configurations, evidence and gaps that are hard to see from the inside, and returns a prioritized remediation plan. A penetration test goes further by having specialists actively try to break in, which is most useful once basic controls are in place.

Rebuild the full assessment at least once a year and review the register more often. Repeat it after significant changes such as an acquisition, a new location, a major new system, a change in IT staff or a security incident.
Include leadership, the people who run finance and operations, whoever manages IT and any key software vendors. Business leaders judge impact, finance understands payment fraud exposure and technical staff judge likelihood and controls. An assessment done only by technical staff tends to rank by technical severity, which is the problem it was meant to solve.
Expect a leadership summary, the critical systems reviewed, findings tied to evidence, a ranked list of risks with recommended treatments and owners, and the decisions leadership needs to make.
Requirements vary by insurer. Many applications ask about specific controls, and a recent assessment makes those questions easier to answer accurately.
