Security architecture & hardening — design review + operational uplift

Architecture-level review and operational hardening across cloud, identity, network and endpoint — driven by validated attack paths from the KeenSafe platform.

The problem

Where teams get stuck

Hardening guides are generic. Architecture diagrams age. The real question is whether the controls in your environment, configured as they are today, actually break the attack paths an adversary would use.

The KeenSafe approach

How we engage

We review architecture against the attack paths the platform actually finds in your environment. Every recommendation is tied to a specific path it closes. Hardening tasks are sequenced by impact, owner and effort.

Methodology

Four-step engagement model

Same rigour every engagement, calibrated to your environment, threat model and regulatory exposure.

STEP 01

Architecture & control inventory

Cloud, identity, network, endpoint and application controls captured against ATT&CK.

STEP 02

Path-driven gap analysis

Each platform-found attack path is mapped to the control that should have broken it.

STEP 03

Hardening backlog

Sequenced by impact, owner, effort. Each item references the path it closes.

STEP 04

Closure validation

Re-run the same attack path after the fix is deployed — proven closure, not assumed.

What you get

Deliverables

Every engagement ships these outputs — reproducible, evidence-backed and ready for executives, engineers and auditors.

Architecture review report

Trust boundaries, identity plane, segmentation and data-flow risk findings.

Path-mapped hardening backlog

Each task carries the attack path it closes, with owner and effort estimate.

Reference architectures

Sector-appropriate target architectures for identity, cloud and network segmentation.

Validated closure

Platform replays the same paths after fixes ship — proven, not assumed.

Scope of engagement

What this engagement covers

Concrete coverage. Clear boundaries. Optional add-on tracks where customers want to extend.

Included
  • Architecture review: cloud, identity, network, endpoint, application
  • Trust boundary mapping with attack-path validation
  • Microsoft Tier-0 model design + privileged access workstation pattern
  • Cloud workload identity hardening (AWS / Azure / GCP)
  • Network segmentation + microsegmentation review and validation
  • Endpoint baseline + EDR tuning to ATT&CK coverage targets
  • Sequenced hardening backlog: each task references the path it closes
  • Closure validation: same attack path replayed after fix to prove it broke
Optional add-ons
  • OT / ICS hardening under IEC 62443 alignment + safety-first model
  • AI / LLM application hardening (RAG, agent, prompt-injection defences)
  • Microsoft Defender / Entra ID deep-dive (sectoral focus)
  • Reference architectures delivered as IaC (Terraform, Bicep, CDK)
  • Quarterly retainer with continuous re-validation
Out of scope
  • Implementation labour for hardening tasks (we design, your team implements; or extend with managed delivery partner)
  • GRC documentation for compliance audit (covered by Compliance Readiness)

What lands on your desk

Sections customers actually see in the engagement deliverable.

  1. 01
    Architecture review report

    Trust boundaries, identity plane, segmentation and data-flow risk findings with attack-path mapping per finding.

  2. 02
    Path-mapped hardening backlog

    Each task references the attack path it closes. Owner, effort and impact estimated.

  3. 03
    Reference architecture

    Sector-appropriate target architectures for identity, cloud and network segmentation. Where requested, delivered as IaC.

  4. 04
    Validated closure record

    Per-fix replay: same attack path re-run after deployment to prove the fix actually broke the chain.

Common questions

Frequently asked

Do you cover cloud and on-prem?
Yes — AWS, Azure, GCP, Microsoft 365, on-prem AD, hybrid identity, network segmentation, endpoint baselines.
How do recommendations stay current?
Continuously. Every new attack path the platform finds is tested against your hardening posture — drift is visible immediately.
Can you do Microsoft Tier-0 / privileged access?
Yes — privileged access workstations, tiered admin model, AD recovery design and the broader Microsoft Tier-0 architecture are a core specialty.
