A secure infrastructure is the foundation of a resilient cybersecurity posture. Testing helps identify weaknesses in networks, servers, and cloud environments.
Infrastructure testing must consider both insider threats and external attacks.
As businesses move to the cloud, securing cloud environments is critical.
Infrastructure security must evolve to counter emerging cyber threats.
Infrastructure penetration testing is an authorised, simulated attack against your network, servers, endpoints, and supporting systems to identify vulnerabilities an attacker could exploit to gain access, escalate privileges, or move laterally. It covers on-premises networks, cloud infrastructure, firewalls, VPNs, Active Directory, endpoints, and any exposed services - testing both what's reachable from the internet and what an attacker could do once inside.
External infrastructure testing simulates an attacker on the internet - it targets your public-facing IP ranges, exposed services, VPN endpoints, and cloud infrastructure, testing whether an outside attacker can breach your perimeter.
Internal infrastructure testing simulates an attacker who's already inside the network (through phishing, a compromised endpoint, a rogue insider, or a lost laptop) - it targets Active Directory, internal servers, network segmentation, endpoint hardening, and privilege escalation paths.
For most organisations, yes - and we typically deliver them as a combined engagement. External testing tells you whether an attacker can get in; internal testing tells you what happens if they do. Modern attacks bypass the perimeter routinely through phishing and credential theft, which means external hardening alone is no longer sufficient.
Testing both is also aligned with the assumptions APRA CPS 234, ACSC Essential Eight, and PCI DSS make about how attackers actually operate.
Vulnerability scans identify known CVEs and misconfigurations against a signature database. Infrastructure penetration testing takes the next step - manually exploiting those vulnerabilities to prove impact, chaining together weaknesses to demonstrate real attack paths, and testing business-context scenarios like privilege escalation to domain admin, lateral movement between segments, and access to specific high-value systems. A scan tells you what's potentially exploitable; a penetration test proves what actually is.
Yes — Active Directory testing is a core part of every internal infrastructure engagement we deliver, and often the most valuable component. Our testing covers common attack techniques including Kerberoasting, AS-REP roasting, DCSync, Pass-the-Hash, unconstrained delegation abuse, and GPO permission misuse - the same techniques attackers use in real incidents.
Findings frequently include excessive privileges, stale accounts, weak service account passwords, and misconfigured trusts that create exploitable paths to domain compromise.
For a straightforward cloud-hosted server or network, infrastructure testing covers it. For cloud-native architectures involving IAM policies, storage buckets, serverless functions, containers, or multi-account structures across AWS, Azure, or Google Cloud, dedicated cloud penetration testing is the right service - the vulnerabilities are architectural, not just configuration-level.
Our team scopes each engagement to match your actual environment, and combined infrastructure and cloud engagements are common where the two overlap.
