What it is

Run a basic security review for small offices: check devices, updates, email settings, passwords, backups and Wi-Fi, then fix the gaps and write a plain-English report. Optionally add ongoing monitoring and staff awareness training.

Your first three steps

  1. Create a standard audit checklist and a sample report, using free guidance from sources like CISA or NIST as a base
  2. Get general liability and professional liability (errors and omissions) insurance, plus a written service contract
  3. Approach local accountants, medical offices and chambers of commerce to offer a low-cost first audit
Who pays

Small offices such as dental practices, accountants, law firms, contractors and shops with no in-house IT person.

How it makes money

Fixed fee per audit, fees for fixing and setting up protection, and an optional monthly retainer for monitoring, updates and support.

Skills that help
  • Networking and device security knowledge
  • Clear written reports
  • Sales and relationship building with business owners
Watch out for
  • Professional liability: if a client is breached after your work, you could be blamed, so use careful contract wording and insurance
  • Clients in health care, finance or law may have extra data rules (such as HIPAA), so check what applies before taking them on
  • Get written authorization before testing or scanning any client network
  • Check whether your state or city requires a business license, and your state's rules on charging sales tax for services
  • Certifications such as Security+ are not legally required but can help win trust
