How to Start a Cybersecurity Consultancy
Going from security work for an employer to your own consultancy: credentials, registration, an EIN, insurance and your first engagement.
A cybersecurity consultancy sells the skills you use in a security role, but you also find the clients, write up each scope and send the invoices. These steps cover the set-up. The cybersecurity consultant invoicing guide linked below explains how to price and bill an assessment.
The BLS page on information security analysts (In the US, last modified August 27, 2026) says "Most information security analysts work for computer companies, consulting firms, or business and financial companies." It also says "Many employers prefer to hire candidates who have information security certification." If you hold certifications, name them in your proposals.
Example of a first engagement invoice, in sample figures: a fixed-fee security assessment at 1 × $2,400.00 and 6 hours of remediation advice at 6 × $150.00 = $900.00 come to $2,400.00 + $900.00 = $3,300.00. Use your own figures; these are only an illustration.
Step-by-step startup guide
Follow these steps to launch your cybersecurity consultant business on solid footing.
- 1
Choose the services you'll sell
Pick a focus, such as security assessments, policy writing or incident response, and the size of client you want to serve.
- 2
Check your credentials
The BLS page on information security analysts (In the US, last modified August 27, 2026) says "Information security analysts typically need a bachelor’s degree in a computer science field, along with related work experience." Ask your state's licensing office whether any service you plan to offer needs a license.
- 3
Register the business
The SBA (In the US, SBA, checked October 31, 2026) says "If you conduct business as yourself using your legal name, you won’t need to register anywhere." For an LLC or another structure, ask a lawyer or an accountant which suits you.
- 4
Get an EIN
The IRS (In the US, IRS, last reviewed or updated October 16, 2026) says "You never have to pay a fee for an EIN."
- 5
Insure the work
The SBA (In the US, SBA, checked October 31, 2026) lists professional liability insurance for "Businesses that provide services to customers" and says "This coverage protects against financial loss as a result of malpractice, errors, and negligence." Ask a licensed agent which policies fit security work.
- 6
Scope, then bill the first engagement
Put the scope, deliverables and timeline in a written proposal, get the client's sign-off, and invoice against it.
Tips for starting your cybersecurity consultant business
- Log your hours on every engagement, fixed-fee work included, so you can see what each job took.
- Keep client findings only in the systems the client approves, and say so in your proposal.
- Plan for quarterly tax payments from your first engagement. The IRS (In the US, IRS, last reviewed or updated September 25, 2026) says "Individuals, including sole proprietors, partners, and S corporation shareholders, generally have to make estimated tax payments if they expect to owe tax of $1,000 or more when their return is filed."
- Ask a lawyer to review your engagement terms before the first client signs.

When this isn't for you
Security work done as an employee, or billed through a staffing agency, doesn't need these steps; they're for people setting up a consultancy.
