“Adequate cyber defenses” is too vague to reduce to one dependable percentage. A useful assessment looks at specific controls, who owns them, how often they are checked, and whether recovery has actually been tested.

You may have seen the claim that only 14% of small businesses have adequate defenses. As far as we can trace it, the number comes from a 2016 Ponemon Institute survey of 598 people at companies with up to 1,000 employees, in which 14% rated their own company's ability to mitigate cyber risk as "highly effective." That is a ten-year-old self-rating, not a measurement of anyone's defenses, so we do not lean on it.

Many small businesses still make security decisions informally or only after something goes wrong. A short written policy and clear ownership are practical starting points. So is knowing where your Canton, Akron, or Massillon area business actually stands.

This self-assessment will help you find out. Answer honestly, and you will have a clear picture of where you stand and what needs attention.

Section 1: Password and Access Management

These questions address how your business handles the keys to your digital kingdom.

1. Does every employee have their own unique login for each system they use?

If employees share accounts or passwords, you cannot track who did what. You also cannot revoke access for one person without affecting others.

2. Are passwords required to be strong and unique for each account?

"Password123" and variations of company names or birthdays are easily guessed. Password reuse means one breach compromises multiple systems.

3. Do you use a password manager to store credentials securely?

Employees who cannot remember unique passwords write them down, store them in spreadsheets, or reuse them. Password managers solve this problem.

4. Is multi-factor authentication (MFA) enabled on all critical systems?

MFA means stolen passwords alone are not enough to access accounts. In a Microsoft study of business accounts in its cloud, turning on MFA cut the risk of an account being compromised by more than 99%.

5. Do you immediately revoke access when employees leave the company?

Former employees with active credentials are a serious risk, whether through malice or because their credentials get stolen later.

Scoring:
- 5 yes answers: Strong access management
- 3-4 yes answers: Moderate gaps that need attention
- 0-2 yes answers: Critical vulnerabilities requiring immediate action

Section 2: Email Security

Email is one of the main ways attackers get in, through phishing, stolen passwords, and fake payment requests. These questions assess your defenses at this entry point.

1. Do you have email filtering beyond basic spam detection?

Advanced email security analyzes content, checks sender reputation, and blocks malicious attachments and links that basic filters miss.

2. Are employees trained to recognize phishing emails?

Training should cover current threats including AI-generated phishing, not just obvious scams from years ago.

3. Do you have a process for employees to report suspicious emails?

If employees do not know what to do with a suspicious message, they either ignore it or click it. Neither is good.

4. Have you configured SPF, DKIM, and DMARC for your domain?

These email authentication protocols, once DMARC is set to enforce, make it much harder for attackers to send email that appears to come from your exact domain. They do not stop look-alike domains.

5. When was the last time you tested employees with a simulated phishing email?

You cannot know if training works without testing. Simulated phishing reveals actual readiness.

Scoring:
- 5 yes answers: Strong email security
- 3-4 yes answers: Some protection but gaps exist
- 0-2 yes answers: High risk of successful phishing attack

Section 3: Backup and Recovery

Backups are your insurance policy against ransomware and data loss. These questions reveal if that policy will actually pay out.

1. Is all critical business data backed up regularly?

Identify your critical data: customer records, financial data, production files, emails, and anything you could not recreate. Is it all covered?

2. Are backups stored in at least two locations, including offsite or cloud?

Local backups can be destroyed by the same ransomware, fire, or flood that takes out your primary systems.

3. Is at least one backup copy stored offline, disconnected from your network?

Ransomware operators look for connected backups and encrypt or delete them too. Offline copies survive even if attackers compromise your network completely.

4. Have you actually tested restoring from your backups?

Backups that have never been tested are backups you cannot trust. Test restores should happen regularly.

5. Do you know your recovery time objective and can your backups meet it?

How long can your business survive without access to systems and data? Can you actually recover that fast?

Scoring:
- 5 yes answers: Solid backup strategy
- 3-4 yes answers: Gaps that could prove costly during an incident
- 0-2 yes answers: Severe risk of unrecoverable data loss

Section 4: Endpoint Protection

Every computer, laptop, and phone is a potential entry point. These questions address device security.

1. Do all company devices have current endpoint protection software?

Traditional antivirus is no longer sufficient. Modern endpoint detection and response (EDR) tools monitor behavior and respond to threats automatically.

2. Are operating systems and software kept updated with security patches?

Unpatched systems are easy targets. Automatic updates should be enabled wherever possible.

3. Do you have policies for personal devices accessing company data?

If employees use personal phones or laptops for work, those devices need security too.

4. Are laptops encrypted so data is protected if devices are lost or stolen?

Full disk encryption means a stolen laptop does not automatically mean stolen data.

5. Can you remotely wipe a lost or stolen device?

When devices disappear, you need the ability to remove company data before it falls into wrong hands.

Scoring:
- 5 yes answers: Well-protected endpoints
- 3-4 yes answers: Moderate endpoint security with room for improvement
- 0-2 yes answers: Devices are a significant vulnerability

Section 5: Network Security

Your network connects everything together. Weaknesses here affect your entire organization.

1. Do you have a business-grade firewall (not just a consumer router)?

Business firewalls provide features like intrusion prevention, content filtering, and VPN support that consumer devices lack.

2. Is your firewall firmware current and regularly updated?

Firewalls with outdated firmware often have known vulnerabilities that attackers exploit.

3. Is your Wi-Fi secured with WPA3 or WPA2-Enterprise?

Open or WEP-secured wireless networks are easily compromised. Guest networks should be separate from business networks.

4. Do remote employees connect through VPN rather than exposing systems directly to the internet?

Direct exposure of remote desktop, file shares, or applications creates easy targets for attackers.

5. Do you know all devices connected to your network?

Unknown devices could be rogue access points, compromised systems, or unauthorized equipment.

Scoring:
- 5 yes answers: Solid network security foundation
- 3-4 yes answers: Network has vulnerabilities that need attention
- 0-2 yes answers: Network security requires significant improvement

Section 6: Policies and Procedures

Technical controls only work when supported by clear policies and trained people.

1. Do you have a written cybersecurity policy that employees have acknowledged?

Policies document expectations. Without them, security is inconsistent and unenforceable.

2. Do you have a documented incident response plan?

When something goes wrong, who do you call? What steps do you take? Figuring this out during a crisis costs precious time.

3. Have employees received security awareness training in the past year?

Threats evolve constantly. Training from two or three years ago addresses threats that no longer exist while missing current ones.

4. Do you have security requirements for vendors and partners who access your systems?

Your vendors' security weaknesses become your security weaknesses when they have access to your data or systems.

5. Do you conduct regular reviews of user access and permissions?

Access accumulates over time. Regular reviews remove permissions people no longer need.

Scoring:
- 5 yes answers: Strong policy foundation
- 3-4 yes answers: Policies exist but need strengthening
- 0-2 yes answers: Policy gaps create significant organizational risk

Interpreting Your Results

Add up your yes answers across all sections for your total score out of 30.

25-30: Strong security posture
You have the fundamentals in place. Keep maintaining and improving them, and reassess regularly so you stay current as threats change.

18-24: Moderate security with notable gaps
You have some protections in place but meaningful vulnerabilities exist. Prioritize addressing gaps in sections where you scored lowest. Consider professional assessment to identify issues this self-assessment may have missed.

10-17: Significant security weaknesses
Your business has substantial exposure to common attack vectors. Multiple areas need immediate attention. A professional security assessment should be a priority, followed by a structured improvement plan.

Below 10: Critical security deficiencies
Your business operates with minimal cyber protection and is exposed to the most common attacks. Getting help to close the biggest gaps first should be a priority.

What To Do Next

If this assessment revealed gaps, you have two choices: address them yourself or get help.

For businesses with internal IT capability, use your scores to prioritize improvements. Focus first on sections where you scored lowest, as those represent your greatest risks.
