What we assess
Hosts and management
Approved servers, management interfaces, exposed services and hardening.
Identity relationships
Administrative access, service accounts and permission boundaries.
Connectivity and segmentation
Allowed paths between applications, hosts and network zones.
Operational controls
Secrets handling, relevant logging and configuration practices within scope.
Who it is for
Infrastructure, IT and security teams managing connected on-premises, cloud or hybrid systems.
Before we start
Share a high-level architecture, authorized assets, identity boundaries, critical dependencies and operational constraints. Agree the starting access level and how shared or outsourced components will be treated.
Methodology
From scope to verified fixes.
Map dependencies before testing components. Combine exposure review and configuration evidence with controlled validation of selected cross-system paths. Keep host, identity and network observations linked so remediation can address the root cause and its dependencies.
- 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 service account has unnecessary privileges across several connected systems.
- An administration path bypasses the intended network restriction.
- A shared secret or unsafe management configuration increases the impact of a single exposed component.
What you receive
A scoped architecture and exposure summary, cross-system findings, affected dependencies, hardening recommendations and prioritized remediation actions with retest criteria.
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 Infrastructure Security Assessment
How does this differ from network VAPT?
Network VAPT emphasizes reachable services and network paths. Infrastructure review can also include host configuration, identity relationships and operational dependencies when access is provided.
Can hybrid environments be included?
Yes, where assets and authorization are clear. Cloud accounts, on-premises ranges and third-party dependencies must each have explicit boundaries.
Will critical systems be tested disruptively?
Criticality and exclusions are agreed before testing. Availability-impacting actions are not assumed to be authorized.
