Network security: a guide for pros
What customers ask, how to win the job, and what to put on your profile.
Offering network security
You review and secure networks for homes and businesses, so customers trust you with their data and devices. A clear scope, a written report and honest limits on what you can promise keep the work professional.
What customers ask
- Is my network secure now?
- What will you change?
- Can you stop a hacker?
- Will the changes break anything?
- How often should we check?
How to win the job
- On the first call, ask the number of devices and users, the data handled, and any past incidents
- Agree the scope in writing, including which devices and accounts you may access
- Review the settings, updates and open ports, and record what you find
- Make changes in steps and test each one so nothing breaks unexpectedly
- Deliver a plain written report with the risks ranked by importance
- Offer a follow up check and explain what the customer must keep doing
What to put on your profile
- Sample report pages with sensitive details removed
- The network types and sizes you secure
- Your scope and access rules, explained in plain words
- Your training, certifications and insurance details
Follow-up that helps the customer
- Offer a check after any major device or software change
- Remind the customer to keep firmware and passwords current
- Send a note on spotting phishing and suspicious logins
Licenses and permits
Network security work is usually not licensed. Check state and local rules for business registration and for how customer data is handled and reported, and keep your insurance and confidentiality terms current.
Questions
What do I do when the customer wants me to access systems outside the scope?
Stop, explain the scope in writing, and ask for a new written agreement before going further.
How do I handle a customer who refuses to change a weak password?
Record the risk in the report, explain the consequences plainly, and let the customer decide with that information in writing.
