Security Architecture Review

A systematic evaluation of IT systems, infrastructure and processes to assess security posture, identify vulnerabilities and weaknesses in the architecture, and confirm alignment with security best practice and industry standards.

Typical engagement15 days for assessment plus one week for reporting.

The problem

What usually brings people to this.

  • Cyber security incidents and anomalies
  • Security configuration issues
  • Poor compliance status
What we do

A systematic evaluation of your security posture, on-premises and in cloud

We review the design and configuration of your IT infrastructure — on-premises or cloud — against cyber security best practice. The primary goal is to identify potential vulnerabilities, risks and weaknesses in the architecture and confirm that it adheres to recognised standards. The output is a risk-rated set of findings with a remediation plan and a target design.

  • 01

    Network security architecture

    Review of network security design and control placement.

  • 02

    Server infrastructure security

    Security architecture review across server and compute infrastructure.

  • 03

    Endpoint security architecture

    Review of endpoint protection design and coverage.

  • 04

    Cloud security architecture

    Security architecture review of cloud infrastructure and its integration points.

Methodology

How the engagement runs.

A defined sequence, so you know what is happening at any point and what comes out of each stage.

  1. 01

    Define security requirements

    Establish the standard the architecture will be measured against.

    • Business and regulatory drivers
    • Applicable frameworks
    • Scope and boundaries
  2. 02

    Identify and classify assets

    Know what is being protected and how much it matters.

    • Asset inventory
    • Data classification
    • Criticality rating
  3. 03

    Design security architecture components

    Map the controls that should exist across the estate.

    • Network controls
    • Identity and access
    • Endpoint and workload controls
  4. 04

    Threat modelling and risk assessment

    Work out what could realistically go wrong and what it would cost.

    • Threat modelling
    • Risk identification
    • Impact and likelihood rating
  5. 05

    Implement security controls

    Define the controls to be put in place and their sequence.

    • Control selection
    • Prioritisation
    • Implementation planning
  6. 06

    Test and validate the architecture

    Confirm the controls work as designed.

    • Control validation
    • Configuration verification
    • Gap confirmation
  7. 07

    Document and communicate security policies

    Leave the organisation able to maintain the posture.

    • Policy documentation
    • Standards and procedures
    • Stakeholder briefing
Typical duration 15 days for assessment and one week for reporting.
Deliverables

What you receive.

  • 04Short-term and long-term target design
Outcome

What changes afterwards.

  • Improved security posture
  • Improved compliance posture
  • Strategic alignment between security and business direction
  • Improved user experience

Technologies and frameworks in scope

  • ISO 27001

Questions

Before you get in touch.

Does this cover cloud as well as on-premises infrastructure?

Yes — the review covers network, server, endpoint and cloud security architecture, whichever combination applies to your estate.

Do you just report findings, or design the fix as well?

Both — the output includes recommendations and remediation plans plus a short-term and long-term target design, not only a list of gaps.

Which frameworks is this assessed against?

ISO 27001 and NIST.

How long does the review take?

15 days for assessment plus one week for reporting.
