Once an attacker is inside — via phishing or a compromised laptop — how far can they reach across your Cyprus network? We start from an assumed-breach position and attempt lateral movement, privilege escalation and access to your most sensitive systems.
We map trust relationships, attack shared credentials and prove whether your segmentation actually contains a breach.
What separates our internal network penetration testing is depth: we don't stop at the first finding, we chain weaknesses until we can prove genuine business impact. We map your real environment, not a generic template, then test every path where trust is granted and every place where controls could be bypassed.
The result is clarity: a prioritised, exploitable-risk view of your internal network attack surface that your team can act on immediately, backed by proof rather than a scanner's guesswork.
The businesses that rely on us understand that untested systems are unquantified risk. A weakness that reaches customer or financial data can trigger a NIS2 and ISO 27001 obligation, damage hard-won client trust, and stall deals while security questionnaires go unanswered. Our internal network penetration testing exists to remove that uncertainty before an attacker — or an auditor — finds the gap first.
By proving exactly what is exploitable and what it would cost, we turn a vague worry into a concrete, fundable remediation plan. Cyprus firms use our reports to close real gaps, satisfy CySEC, GDPR and NIS2 expectations, and demonstrate genuine due diligence to clients, partners and insurers — with a free retest to prove the fixes hold.

How we run your engagement
Kick-off & scoping. A short call to agree goals, in-scope assets and rules of engagement, so your internal network penetration testing is safe, authorised and aimed at your real business risk.
Mapping & discovery. Before touching anything we map the full attack surface in scope, so nothing exploitable slips through.
Hands-on testing. Cyprus-based specialists exploit and chain weaknesses manually — the flaws scanners walk straight past — to show genuine impact.
Reporting. Each issue is verified, CVSS-rated and documented with a step-by-step reproduction and a practical fix your team can apply.
Free retest. Once you have remediated, we re-test at no extra cost to confirm the attack path is truly closed.
Tools & techniques
In practice, your internal network penetration testing focuses on lateral movement & privilege escalation, credential harvesting & reuse attacks and network segmentation validation and the ways they can be chained together.
We combine disciplined reconnaissance with hands-on exploitation. Service discovery and version mapping start with Nmap and targeted enumeration; where a scanner flags a weakness we validate it by exploitation rather than trusting the alert. Credentialed and uncredentialed checks, manual configuration review and safe exploitation of real attack paths give you an accurate picture of what an attacker on — or reaching into — your network could actually achieve.
Every step follows a documented rules-of-engagement so testing stays non-disruptive to production. We map how one foothold could lead to lateral movement across your Cyprus network, then show the exact chain rather than a list of theoretical CVEs.
When you need this engagement
You are deploying, changing or relying on systems where lateral movement & privilege escalation would be business-critical
You are merging networks, moving office or migrating infrastructure
A regulator, insurer or enterprise client requires an infrastructure penetration test
You suspect legacy systems or flat network segmentation are increasing your risk
You need annual NIS2 or ISO 27001 evidence for your Cyprus operations
What you receive
Internal attack-path narrative
Compromise chain with evidence
Segmentation and hardening guidance
Free retest after remediation

When your internal network penetration testing wraps up, you receive a clear, audit-ready report plus a walkthrough call with your team. Inside you will find:
A concise executive summary that management and the board can act on
Every technical finding with a reproducible, copy-paste proof of concept
CVSS v3.1 ratings and plain-language business impact for each issue
Practical, prioritised remediation your developers can implement straight away
A free retest and updated finding status once fixes are in place
A signed attestation letter for clients, auditors, GDPR, NIS2 and ISO 27001

What you gain
By the end of your internal network penetration testing, you will know exactly which weaknesses a real attacker could exploit, what it would cost your business, and the precise order in which to fix them — backed by evidence, not a scanner’s guesswork. Cyprus firms use our findings to close critical gaps, satisfy client and regulator security questionnaires, and demonstrate due diligence for GDPR and NIS2. With a free retest included, you also get documented proof the issues are resolved.
Working with us
Every internal network penetration testing begins with a short, no-obligation scoping call to understand your goals, environment and constraints, followed by a fixed-price proposal. Most work is delivered remotely, and because we are based in Cyprus we work in your timezone with on-site visits across Limassol, Nicosia and island-wide where it helps. We keep you updated throughout and flag any critical finding immediately rather than waiting for the report. Everything is covered by a signed NDA and safe, non-disruptive testing that protects your production systems. You receive your report, a walkthrough and a complimentary retest once fixes land. Engagements are typically booked one to three weeks ahead, and urgent testing can often be arranged — just email hi@cypruspentest.com.
