Infrastructure Security
Assessment

Uncover hidden vulnerabilities across your on-premise and hybrid infrastructure from Active Directory and network devices to internal servers and critical services before they become your next breach.

What We Test in Your Infrastructure

Comprehensive coverage spanning Active Directory, network devices, servers, and internal services.

Kerberoasting and AS-REP Roasting

Identify service accounts vulnerable to Kerberoasting and user accounts with Kerberos pre-auth disabled for AS-REP roasting attacks.

Pass-the-Hash and Credential Replay

Test for credential reuse, pass-the-hash, and pass-the-ticket opportunities across the domain environment.

Delegation and Trust Abuse

Assess constrained and unconstrained delegation configurations, cross-domain trusts, and forest trust relationships for escalation paths.

ACL and GPO Misconfigurations

Identify overly permissive ACLs on AD objects and GPO misconfigurations that enable privilege escalation or persistent access.

Group Membership and Nested Groups

Audit group memberships for excessive privileges, nested group escalation paths, and inactive accounts with privileged access.

Domain Admin Path Analysis

Map all paths from a compromised user to Domain Admin through group memberships, ACLs, and trust relationships.

Router and Switch Configuration

Review router and switch configurations for weak ACLs, insecure management interfaces, VLAN misconfigurations, and default credentials.

Firewall Rule Audit

Analyse firewall rulebases for overly permissive rules, shadow rules, any-any policies, and rule conflicts that create security gaps.

Wireless Network Testing

Test enterprise Wi-Fi for rogue access points, WPA2/WPA3 weaknesses, EAP bypass, and captive portal abuse that enables network access.

Network Segmentation Validation

Validate VLAN separation, test for VLAN hopping, and assess whether sensitive segments are properly isolated from user networks.

VPN and Remote Access

Test VPN gateways for weak pre-shared keys, outdated protocols, authentication bypass, and vulnerabilities in remote access infrastructure.

Legacy Protocol Exposure

Identify and assess systems running SMBv1, Telnet, FTP, and other legacy protocols that expose the network to known attacks.

Server Hardening Review

Evaluate Windows and Linux server configurations against CIS Benchmarks for OS hardening, service minimisation, and security policy compliance.

Database and File Share Security

Audit internal databases and file shares for weak authentication, excessive permissions, and sensitive data accessible from compromised hosts.

Internal Application Security

Assess internally-exposed web applications, admin panels, and management interfaces for authentication weaknesses and access control gaps.

Patch and Vulnerability Management

Identify unpatched CVEs, end-of-life software, and outdated service versions that provide exploitation opportunities for attackers.

Endpoint Detection Posture

Review EDR, antivirus, and host-based security configurations to determine whether they would detect and block real attack techniques.

Logging and Detection Coverage

Review SIEM, endpoint detection, and event logging configurations to determine whether your team would detect a real attacker in your environment.

How We Conduct an Infrastructure Security Assessment

A structured six-phase process aligned with PTES and NIST SP 800-115, from initial scoping through verified remediation.

Phase 01
Scoping

Define in-scope assets including networks, IP ranges, AD domains, servers, and services. Agree on testing windows and rules of engagement.

01
02
Phase 02
Reconnaissance

Internal network scanning, service enumeration, and Active Directory reconnaissance to map the full attack surface.

Phase 03
Vulnerability Identification

Manual and automated discovery of misconfigurations, unpatched CVEs, weak credentials, and exploitable AD relationships.

03
04
Phase 04
Exploitation and Movement

Safe, controlled exploitation to demonstrate privilege escalation and lateral movement paths across the infrastructure.

Phase 05
Reporting

CVSS-scored findings with attack path diagrams, executive summary, and per-issue remediation steps mapped to CIS Controls.

05
06
Phase 06
Re-Test

Free re-test after remediation to confirm all identified vulnerabilities and attack paths have been effectively resolved.

Built for Organisations With Real Infrastructure

Enterprises and Mid-Market

Organisations with significant on-premise or hybrid infrastructure including Active Directory, internal networks, and server fleets requiring comprehensive security validation.

Regulated Industries

Financial services, healthcare, and government organisations needing infrastructure security evidence for PCI-DSS, HIPAA, RBI, or ISO 27001 compliance.

Post-Incident Recovery

Organisations recovering from a breach needing independent validation that infrastructure attack paths have been closed and security controls are effective.

Questions We Get Asked Often

Infrastructure security assessment identifies vulnerabilities across your on-premise and hybrid environment including Active Directory, network devices, servers, and internal services. It simulates real-world attacks to demonstrate how far an attacker could reach.

Yes. We assess hybrid infrastructure including on-premise networks connected to cloud environments via site-to-site VPNs, hybrid Active Directory, and cloud-managed endpoints.

We assess Kerberoasting, AS-REP roasting, delegation abuse, ACL misconfigurations, GPO-based privilege escalation, and domain admin path analysis. All testing is aligned with PTES and NIST SP 800-115.

No. We follow strict rules of engagement that define testing windows, off-limits systems, and escalation procedures. All exploitation uses controlled techniques designed to demonstrate impact without causing damage or unplanned downtime.

Typical engagements take 7 to 15 business days depending on infrastructure size, complexity, and scope. We provide a precise timeline after initial scoping discussions.
