Offensive security

Find it before someone else does

Penetration testing, red team engagements, and incident response, run against a defined objective, reported with evidence, and re-tested after the fix.

In short

Rynexor provides offensive security testing: penetration tests, red team engagements, and incident response for companies in Türkiye, Cyprus, the Gulf, and Europe. Every engagement runs against a written scope and a defined objective, and every finding ships with reproduction steps and evidence of impact.

Attack surface, declared versus discovered Four concentric bands around a centre point. Innermost: declared assets, the list a client provides. Outside it: discovered assets such as subdomains, staging and development environments. Then inherited exposure through third parties and integrations. Outermost: leaked material such as credentials, public repositories and stale DNS records. Scattered marks across the outer bands represent findings that sit outside the declared list. Declared the asset list you sent Discovered subdomains, staging, dev Inherited third parties, integrations Leaked credentials, repositories, DNS
Structural illustration, not measured data. The declared list is where an engagement starts; it is rarely where the exposure ends.

What this covers

4 areas

01

External penetration testing

Everything reachable from the internet: web applications, APIs, mail infrastructure, exposed management interfaces, and the DNS records that keep pointing at servers nobody remembers renting.

02

Web and API assessment

Authentication and session handling, access control between tenants and roles, injection paths, business logic that can be driven somewhere it was not meant to go. Manual work, not a scanner report reformatted.

03

Red team engagement

A goal-based exercise against your live environment with a small number of people in the loop. The point is not a list of vulnerabilities. It is finding out whether anyone notices, and how long it takes.

04

Incident response

Containment, scoping, and root cause when something has already happened. We work to establish what was reached and what was not, because "we think it was limited" is not an answer you can give a regulator.

How it runs

Stages, in order. Each one produces something you keep.

  1. Stage 01

    Scope and rules of engagement

    Targets in scope, targets explicitly out, testing windows, escalation path, and what happens if we find something critical on the first afternoon. Signed before anything starts.

  2. Stage 02

    Reconnaissance

    Mapping what actually exists, which is routinely larger than the asset list provided. Forgotten subdomains and staging environments are not edge cases; they are most of the way in.

  3. Stage 03

    Exploitation

    Proving reachability and impact with evidence. We chain findings, because the individually-medium issues are usually the ones that combine into something that matters.

  4. Stage 04

    Reporting

    Findings with reproduction steps, evidence, and a fix that fits your stack. Prioritised by what is exploitable in your environment, not by a generic score.

  5. Stage 05

    Remediation testing

    We re-test the fix. A closed ticket is not the same as a closed vulnerability, and the difference is where breaches live.

What you get

  • Technical report with reproduction steps and evidence
  • Executive summary written for people who do not read the technical report
  • Prioritised remediation plan mapped to your stack
  • Remediation re-test and a revised report
  • A debrief call where you can argue with our findings

Questions we get asked

What is the difference between a penetration test and a red team engagement?

A penetration test enumerates what is vulnerable across an agreed scope within a set window. A red team engagement works toward one objective (domain admin, a specific dataset, a crown-jewel system), using whatever route works, and measures whether your detection notices. A test tells you what is broken; a red team tells you what happens when someone uses it.

Will testing take our systems down?

Denial-of-service testing is excluded unless you specifically ask for it and we agree a window. Anything with a plausible availability impact is flagged before it runs, not after. Production testing carries residual risk and the rules of engagement say so in writing.

Do you need credentials and source code?

It depends what question you want answered. Black-box testing shows what an outsider reaches. Authenticated and source-assisted testing finds considerably more per day of effort, because time goes into finding flaws instead of finding the application. Most engagements are worth running authenticated.

How is our data handled during an engagement?

Evidence is encrypted at rest, shared through a channel you control, and destroyed on a schedule you set. Access is limited to named individuals for the duration. The specifics are on our Trust Center page.
