Security Architecture & Engineering
Security architecture defines how identity, access, data, network, cloud, and monitoring controls fit together across an environment. Our engineers ensure those designs can be implemented reliably and maintained over time. Together this forms the foundation that allows an organization to operate securely at scale.
Architecture as the Foundation for Security
Armature Systems works with organizations to design architectures that match real technical constraints, support existing and future workloads, and provide a clear model for how security controls should function across systems.
We design security stacks that span network, endpoint, identity, cloud, and data layers. This includes architecting how technologies such as firewalls, segmentation controls, network sensors, EDR, CASB/DLP, and cloud native protections fit together in a cohesive model. The goal is to reduce fragmentation, eliminate overlapping tools, and create an architecture that can be operated consistently.

A security program only works if the underlying architecture supports it.
Many issues including identity sprawl, flat networks, inconsistent logging, fragmented cloud guardrails, and overlapping tools are symptoms of architectural misalignment rather than individual control failures.
Our work focuses on defining security architecture that reflects:
- how applications and data are built and accessed
- where trust boundaries exist
- how identity is managed across cloud and on-prem environments
- what controls are feasible to implement
- how workloads communicate
- how teams operate day to day
A key part of architectural work is reducing operational overhead. Many environments accumulate tools that were never designed to work together. We help define architectures where platforms support one another instead of competing for visibility or control. This improves consistency, simplifies operations, and creates a foundation that teams can realistically maintain.
This creates a security foundation that is realistic, maintainable, and tied directly to engineering decisions.
Architecture Domains we Cover
Security architecture spans multiple layers of an environment. We design across the following domains:
Identity & Access Management
- Identity flow and trust relationships
- Authentication and MFA patterns
- Role and permission models
- Privileged access requirements
- Federation and SSO
- Access governance alignment
Cloud Security Architecture
- Cloud landing zones and guardrails
- Network and security group models
- Key management and secrets handling
- Data storage protections
- Logging, monitoring, and event routing
- Identity and access in cloud-native systems
Network Security Architecture
- Segmentation aligned to applications and data
- Zero Trust network design
- Firewall and inspection placement
- Remote access and private connectivity
- Integration with identity-based policies
- Placement of security sensors and visibility points across campus, data center, and cloud environments
Application & Data Security Architecture
- Data classification and protection patterns
- Application trust boundaries
- API and service-to-service authorization
- Secrets management
- Encryption and key rotation models
- Placement of DLP, CASB, and data exfiltration controls within application and cloud architectures
Logging, Telemetry & Detection Architecture
- Logging strategy based on investigation requirements
- Event source identification and normalization
- Routing into SIEM/XDR platforms
- Mapping logs to detection and response workflows
- Ensuring telemetry coverage for critical assets
Architecture Design & Engineering Outputs
Architecture only adds value when it can be implemented.
We translate design into engineering deliverables that can be executed without ambiguity:
High level architecture diagrams that define major components, trust boundaries, and control layers
Low level design documents detailing how controls are applied across identity, network, cloud, and applications
Data flow and access flow diagrams that clarify how systems interact
Segmentation plans aligned to workloads
Logging and telemetry specifications
Integration plans for existing infrastructure and tools
Architecture patterns for campus, data center, and cloud environments
Roadmaps that sequence implementation in a practical, achievable order
Engineering Feasibility & Decision Support
Security architecture often requires choosing between multiple valid solutions.
We help evaluate:
- what is feasible within existing infrastructure
- what requires new tooling or platform changes
- what should be retired or consolidated
- where dependencies exist between identity, cloud, network, and applications
- how changes impact operations, automation, and detection

Integration Alignment
Security architecture is tightly connected to implementation. The designs we produce are structured to support:
clean handoff to engineering and cloud teams
alignment with Solution Integration services
readiness for automation and SOAR workflows
support for future MDR onboarding and detection use cases
How we work
Assess
We review the current environment, identity, network, cloud, applications, logging and identify architectural gaps, constraints, and dependencies.
Design
We develop high-level and low-level security architectures across the relevant domains, aligned to your program requirements and operational realities.
Validate
We work with engineering, IT, cloud, and security teams to ensure designs are feasible, understood, and ready for implementation.
Support Implementation
We can partner through Solution Integration to help build, configure, or migrate systems based on the architecture.
