What we assess
Exposure and services
Approved IP ranges, reachable services, management interfaces and unnecessary exposure.
Known weaknesses
Version and configuration observations, validated where feasible and separated from scanner assumptions.
Segmentation
Permitted paths between agreed zones and access to sensitive services.
Service protections
Authentication controls, transport configuration and hardening relevant to the discovered services.
Who it is for
IT directors, infrastructure teams and security owners reviewing perimeter exposure, internal segmentation or a network change.
Before we start
Provide owned or authorized IP ranges, exclusions, service criticality, maintenance windows and a technical contact. Shared infrastructure and third-party addresses require explicit authorization and must not be inferred from DNS alone.
Methodology
From scope to verified fixes.
Confirm asset ownership and permitted ranges before discovery. Correlate exposed services with their configuration and validate a bounded selection of attack paths. Internal and external vantage points answer different questions and are defined separately in scope.
- Agree authorization, coverage, test limits and evidence handling.
- Discover and manually validate candidate weaknesses.
- Report confirmed findings, unverified observations and coverage limitations distinctly.
- Discuss remediation and retest the specified fixes within the agreed window.
Typical issues we look for
Examples of possible issues, not findings from R53SEC client engagements. Actual results depend on the system and scope.
- A management service is reachable from an untrusted network segment.
- An outdated service has a relevant weakness that can be safely validated in the approved environment.
- A segmentation rule allows a path that the documented network policy intends to block.
What you receive
An approved-asset exposure inventory, validated weaknesses with affected endpoints, segmentation observations, prioritized fixes and explicit coverage limitations.
The report includes an executive summary, finding identifiers, severity rationale, impact, evidence, remediation and coverage limitations. CVSS is included where appropriate with its version, vector and assumptions. Retest scope, timing and commercial terms are agreed before work begins.
Questions about Network VAPT
How do internal and external assessments differ?
External testing examines approved internet-facing assets. Internal testing starts from a defined internal position to review trust boundaries and reachable services.
Is every discovered host automatically in scope?
No. Discovery does not grant authorization. Ownership, permitted address ranges and exclusions govern what can be assessed.
Are brute force and disruptive exploitation included?
They are not assumed to be allowed. Any intrusive technique requires a documented objective, explicit authorization and agreed stop conditions.
