Find out how your systems work — and where they need attention.
Systems often grow one decision at a time. Eventually, nobody has the full picture. We review how your applications, infrastructure and external services fit together, where they depend on each other and what makes them difficult to maintain.
What we look at
- The main applications, where they run and the people or suppliers responsible for them.
- How data moves and which services depend on each other.
- Access between systems, exposed services and potential points of failure.
- Changes that are difficult to deliver, recurring faults and missing operating information.
What you receive
- An agreed overview of the systems and their main dependencies.
- Findings explained in terms of service disruption, security or maintenance.
- Options for improvement, including the cost and effort assumptions that need checking.
- An ordered set of next actions for management and the technical team.
What is a security architecture review?
It examines who and what your systems trust: which accounts can reach which data, how applications connect, where access is restricted and what could happen if one part is compromised.
We can review an existing setup or proposed change, explain weak assumptions and compare improvements. This complements penetration testing: a test investigates exploitable weaknesses within an agreed scope, while an architecture review examines how the design creates or limits exposure.
Example: an internal reporting tool shares a powerful database account with another application. We examine what each application actually needs and plan how to separate access without breaking the workflow.
A practical example
A business application stops working whenever one old server is restarted. We trace the dependency and compare ways to remove it, including the changes and testing each option needs.
Illustrative example, not a claim about a completed client project.
Questions about this service
Do we need an up-to-date system diagram?
No. Existing information helps, but a review can include building a useful system overview with your team. We agree how much discovery is needed before starting.
Can you review an existing system rather than a new design?
Yes. Inherited systems, undocumented integrations and environments maintained by several suppliers are common reasons for a review.
