Cybersecurity companies test and protect your systems: penetration testing of websites, apps and networks, vulnerability assessments, security reviews of code and cloud setups, staff awareness training, and monitoring or incident response. Some also help you prepare for audits against standards your customers ask for.

Security work is only as useful as the report you get. Ask for a sample report with the client details removed, check how findings are rated and explained, and agree in writing what may be tested, when and by whom.

What to check before you hire

  • A written scope and rules of engagement before any test starts.
  • A sample report: clear findings, risk ratings, proof and fix advice.
  • Named testers and the certifications they hold, which you can verify with the issuing body.
  • A free or low-cost re-test after you fix the findings.
  • How they store and delete your data and test results.
FAQ

Questions about cybersecurity companies

What is a penetration test?
An authorised, simulated attack on your website, app or network to find weaknesses before someone else does. You get a report of what was found and how to fix it.
How often should I run a security test?
Many businesses test at least once a year and after major changes, such as a new app release or a cloud move. Your customers or industry rules may ask for a specific schedule.
Can a security company guarantee I will not be hacked?
No. Testing and monitoring lower the risk, but no honest provider guarantees zero incidents. Be wary of anyone who does.
How are these companies ordered?
By Trusted IT Firms' listing order: editor rank, featured status and profile completeness. See the ranking methodology page.
