Free Cybersecurity Tools for Small Businesses, SMBs & Startups

How to get started with cybersecurity at no cost

The cheapest way to start a cybersecurity program is to measure yourself against a recognized framework before you spend anything on tooling or consultants. A structured self-assessment tells you what you already have in place, where the real gaps are, and what to fix first, so your first security dollars go to the highest-risk gaps instead of guesswork.

Every free tool on this page follows the same approach. You capture a short company profile, work through each control or criterion in your chosen framework, and mark it compliant, partially compliant, non-compliant, or not applicable. Each gap is scored for likelihood and impact on a 5x5 risk matrix and ranked Low, Medium, High, or Critical. You then download a professional PDF or Word report with an executive summary, detailed findings, and a phased remediation roadmap across 30, 90, 180, and 365 day horizons.

The tools run entirely in your browser: answers are saved locally on your device and reports are generated client-side, so your assessment data is not transmitted to IRM or any third party. The result is a credible, framework-based starting point you can share with executives, customers, investors, and insurers, produced in an afternoon at no cost.

Which free tool should I start with?

Pick the tool whose framework matches your situation. If in doubt, most small and medium businesses should start with the CIS Gap Assessment at the IG1 scope (essential cyber hygiene), and Canadian organizations should start with the Cybersecurity Baseline Assessment against Canada's national standard.

Free AI Governance for small businesses

AI governance is no longer an enterprise-only concern. Small businesses adopting AI-powered apps, agentic systems, and agentic workflows face the same questions from customers, partners, and regulators: what AI do you use, what could go wrong, and who is accountable? Two of the free tools address this directly, at no cost.

The AI Governance Playbook builds a tailored AI governance framework for your business and delivers findings, recommendations, and a 90-day action plan aligned to the NIST AI Risk Management Framework, ISO/IEC 42001, and the EU AI Act. The ISO 42001 Gap Assessment then measures you against ISO/IEC 42001:2023, the international standard for AI Management Systems, covering the Clause 4 to 10 requirements and all 38 Annex A controls, useful when you are preparing for certification or responding to responsible-AI due diligence.

Closing the gaps is where most organizations want help. IRM's Governance, Risk & Compliance services turn assessment findings into implemented controls and evidence habits, and our Virtual CISO services take teams from first remediation through certification readiness for SOC 2, ISO 27001, ISO 42001 and CMMC.
