Frequently asked questions

How do you choose the best cybersecurity companies in Türkiye?

Ask for the team's certifications (OSCP, CISSP) and a sample report; put the test scope and the legal authorisation text in writing. Compare candidates on the same project scope, delivery terms and maintenance costs. The CompAtlas category list is not a quality or turnover ranking; sponsored visibility is not a measure of success.

How do you choose a Cybersecurity company?

Ask for the team's certifications (OSCP, CISSP) and a sample report; put the test scope and the legal authorisation text in writing.

How long does a Cybersecurity project take and what does it cover?

A penetration test is usually a few weeks of work, and a verification test is needed after findings are fixed. Continuous monitoring (SOC) is a separate subscription service.

How are cybersecurity companies on CompAtlas verified?

Before each company goes live, we check that its website is live; personal data is filtered out and only corporate information is kept. For details, see the data methodology linked from the About page.
