Network VAPT · External & Internal

Know exactly how far an attacker gets inside your network.

External, internal, Active Directory and wireless testing by CRTP and PNPT-certified testers. We map your real attack surface, break in the way intruders do, and show you the path from an exposed service or a stolen laptop to your most sensitive systems. Delivered remotely for clients worldwide, or on-site across Pakistan when the scope calls for it.

Scanners list weaknesses. We prove the attack path.

A vulnerability scan tells you which hosts run outdated software. Our network penetration testing services tell you what an attacker can actually do with that information. We start where they start: enumerating your external footprint, finding forgotten subdomains, exposed management interfaces, VPN portals and mail gateways, then validating every weakness by hand. Findings are chained rather than listed in isolation, so you learn whether a medium on one host becomes a critical when combined with a weak credential on another.

Internal network penetration testing assumes the perimeter has already failed. Starting from a standard user account or a device plugged into the LAN, our testers map Active Directory attack paths. Kerberoasting, delegation abuse, Active Directory Certificate Services (AD CS) misconfigurations, credential reuse and weak segmentation between user, server and payment zones are all in play. The goal is not a long list of hosts. It is the shortest reliable route to domain admin and the sensitive data behind it, documented step by step so your team can close it.

We deliver network VAPT remotely for organisations worldwide and on-site in Pakistan. At home, banks, telecom operators and government contractors need testing that supports SBP, PTA and SECP expectations, as well as the security questionnaires of their own overseas clients. Wireless security assessments, firewall reviews and VPN testing sit inside the same engagement. Work on production networks runs in agreed windows under formal Rules of Engagement, and anything critical is escalated straight away rather than held for the report.

What we test across your network.

External Penetration Testing

Attack-surface mapping and perimeter testing of everything reachable from the internet: exposed services, VPN portals, mail, DNS and the hosts nobody remembered were still online.

  • Subdomain & asset discovery
  • Exposed service exploitation
  • Password spraying against portals

Internal Network Penetration Testing

Assumed-breach testing from a standard user account or a device on the LAN. We find out what a phished employee or a stolen laptop can reach, and how quickly.

  • Low-privilege assumed-breach start
  • Lateral movement & credential reuse
  • Legacy protocol abuse (LLMNR, SMB relay)

Active Directory Penetration Testing

Attack paths through your domain, from Kerberoasting and delegation abuse to AD CS and Group Policy weaknesses, worked through to domain admin.

  • Kerberos & delegation attacks
  • AD CS & GPO misconfigurations
  • Tiering & privileged access review

Network Segmentation Testing

Proof that your VLANs, firewalls and zones actually hold. We test whether a compromised guest, user or branch segment can reach payment, server or management networks.

  • Zone-to-zone reachability tests
  • Payment & server zone isolation
  • Firewall rule effectiveness

Wireless Security Assessment

On-site testing of corporate and guest Wi-Fi: WPA2 and WPA3 handshake and enterprise attacks, rogue access points, evil twin scenarios and client isolation.

  • WPA2/WPA3 & 802.1X attacks
  • Rogue AP & evil twin scenarios
  • Guest-to-corporate isolation

VPN & Remote Access Testing

SSL VPNs, RDP gateways, jump hosts and remote-worker tooling are the front door now. We test authentication, MFA enforcement, split tunnelling and what a user can reach after login.

  • MFA bypass & weak auth checks
  • Split tunnelling & routing leaks
  • Post-authentication lateral reach

Firewall & Configuration Review

A white-box pass over firewall rulebases, switch and router configs and hardening against CIS Benchmarks, catching what black-box testing cannot see from the outside.

  • Rulebase & any-any rule review
  • CIS Benchmark hardening gaps
  • Management plane exposure

Authenticated Vulnerability Assessment

Broad, authenticated scanning across the estate to baseline patch and configuration state, run by an InsightVM Certified Administrator and triaged by hand so you receive real risk rather than a raw export.

  • Authenticated internal & external scans
  • False-positive triage by a tester
  • Recurring cadence available

How an engagement runs.

  1. / 01

    Scope, Windows & Rules of Engagement

    Under NDA from the first call, we define scope by IP ranges, CIDR blocks, domains and named segments, and agree testing windows, exclusions and emergency contacts before a single packet is sent.

  2. / 02

    Reconnaissance & Attack-Surface Mapping

    Externally, passive and active discovery of every internet-facing asset, including the ones missing from your inventory. Internally, host and service enumeration, domain reconnaissance and trust mapping without noisy, disruptive scanning.

  3. / 03

    Exploitation & Privilege Escalation

    Manual exploitation of validated weaknesses, credential attacks and Active Directory abuse, chained into end-to-end attack paths. Anything with availability impact is agreed in advance, and any critical is escalated to your named contact as soon as it is confirmed.

  4. / 04

    Reporting & Remediation Roadmap

    Leadership gets an executive summary; engineers get a technical report with reproducible steps, evidence and a remediation roadmap ordered by attack path, not by CVSS alone. Then a private debrief call with the people who will fix it.

  5. / 05

    Remediation Support & Retest

    Once fixes are in, we re-run every reported finding and update the report with verified status. On a clean retest we issue an attestation letter summarising scope, method and outcome for anyone who needs the result without the technical detail.

Why teams choose Zencryptix.

  1. / 01

    Certified on the attacks that actually matter

    CRTP, PNPT and OSCP holders who specialise in Active Directory and internal attack paths rather than general-purpose scanning.

  2. / 02

    Safe on production by design

    Agreed windows, throttled scanning, no destructive actions without sign-off and a named stop contact throughout. Your uptime matters as much as our findings.

  3. / 03

    Evidence that travels

    Reports aligned with PTES and NIST SP 800-115, written for a US or EU customer's security team and for SBP, PTA and SECP expectations at home.

Common questions.

It should not, and we plan so that it does not. Scan rates are capped, any exploit that could affect availability is cleared with you before it runs, and production testing stays inside windows you choose. A named contact on your side can pause the engagement at any time.
By IP ranges and CIDR blocks for external and internal testing, plus domains, named segments, VLANs or SSIDs where relevant. We also record explicit exclusions such as fragile legacy systems. If reconnaissance uncovers assets outside the agreed scope, we tell you and wait for approval before touching them.
For external testing, nothing at all. For internal testing we work over a VPN account, a jump box you provision, or a small hardware device connected to your LAN. Wireless assessments need someone physically in range, which we provide on-site in Pakistan; for clients elsewhere we work through a device you connect for us.
Most engagements run two to four weeks from first scan to final report. Live host count, the size of the Active Directory environment and whether wireless or segmentation testing is included all move that figure; large multi-site estates can take up to six. Those same factors, not a host count multiplied by a rate, set the effort behind the quote, which you receive with a timeline within 48 hours of scoping.
In most internal engagements, a lot. Active Directory is where a foothold turns into full compromise, so our CRTP and PNPT-certified testers spend the bulk of internal time on credential attacks, ticket abuse, delegation, AD CS weaknesses and privilege escalation paths. Hybrid estates with an on-premises domain are handled the same way.
A technical report with reproducible steps, a severity-mapped remediation roadmap and an executive summary, followed by a private debrief. One retest of reported findings is included in a standard engagement: after you remediate, we re-verify each one and update the report with its current status. On a clean retest we issue an attestation letter covering scope, methodology and outcome, designed to be forwarded to customers and auditors while the technical report stays internal.
