Secure the Infrastructure
Behind Your Business.
Cloud environments, identity systems, networks and workloads have become deeply connected. TMG Security helps organizations assess these environments, identify security weaknesses and strengthen the infrastructure supporting their applications and data.
Your Infrastructure Is No Longer Inside One Network.
Modern environments create more flexibility, but also introduce more identities, services, trust relationships and configuration dependencies.
Security therefore needs to extend beyond individual servers. The question is no longer only whether a host is patched — it is what an identity can reach, what a service is exposed to, and which boundaries actually hold.
Every Connection Creates a Security Boundary.
Scroll to travel down through the stack, one layer at a time.
Secure Every Layer of the Infrastructure.

Identity Has Become the New Perimeter.
In a cloud environment the network is no longer the main boundary. A role, a policy or a key can be the difference between a contained service and access across an entire account.
That is why identity and access controls sit at the centre of modern infrastructure security. Most meaningful findings are not about a single misconfigured setting — they are about what a given identity can reach once every permission and trust relationship is followed through.
Different Clouds. One Security Strategy.
Each provider has its own controls and its own defaults. The security questions underneath them are the same.

Applications Are Moving Into Layers.
Each layer has its own access model. Findings usually live in the relationship between two of them.

You Can’t Secure What You Can’t See.
Most environments contain more than anyone has mapped. The first job is establishing what exists and how it connects.
Twelve categories, assessed as relationships.
Categories of weakness we assess, described at a level useful for scoping. Findings are documented with technical detail privately to your team.
A Configuration Is Only Important When It Creates Risk.
A long list of configuration deviations is easy to produce and difficult to act on. Most of it will never matter, and the items that do matter get buried alongside the ones that do not.
Assessment should focus on the relationship between technical configuration and business risk: which settings create exposure, what that exposure makes reachable, and what reaching it would actually mean. That is what turns a findings list into a plan.
When Should Infrastructure Security Be Revisited?
Findings your team can act on.
Which of these apply depends on engagement scope.
Weaknesses identified across the environment in scope, with the reasoning behind each.
Settings that widen exposure or weaken a boundary, described precisely enough to locate.
What a finding means in your environment rather than against a generic scoring table.
Supporting detail so findings can be verified rather than taken on trust.
Practical direction on addressing each finding, including where the change belongs.
An order of work, so limited engineering time goes to what matters most.
Verification that addressed findings no longer reproduce, within the agreed retest scope.
How this practice is put together.
Understand both infrastructure and security implications.
Treat identity and access as core security boundaries.
Connect infrastructure security to the applications running on it.
Account for modern workload architectures.
Look at relationships rather than isolated configurations.
Connect infrastructure security with offensive, defensive and application security.
Infrastructure sits between attack and defence.
Each practice answers a different question about the same environment.
