Certifications
Team certifications
The certifications below are professional credentials held individually by members of the RRNK Security team. We show them as text only, and we explain plainly what each one proves — and what it does not.
Certifications held by team members
Every certification in this list requires passing a time-limited practical examination, not only a multiple-choice test.

These are certifications held by individual members of the team. They are not company-level accreditations, and they do not make RRNK Security an accredited organisation or an official partner of any certification body.
What these certifications mean
They mean the tester responsible for your engagement has demonstrated practical skill to an independent certifying body and is professionally accountable to that body’s code of conduct. They do not mean our organisation is accredited.
What we do not claim
