Implementation & Management
We help develop your organization's security architecture
We help you understand, document and develop your organization's security architecture - the relationships between security elements, governance principles and policies that determine how systems interact and how data flows.

Security Architect is a SEQRED service covering documentation, assessment and development of it, ot and cloud security architecture.
Implementation & Management
Every organization has a security architecture - a set of relationships between security elements and the principles that govern them. The problem is that it's often undocumented, inconsistent or hasn't kept pace with infrastructure growth. The result is flat networks without segmentation, inconsistent access policies, unclear trust boundaries and lack of data flow visibility. We help map, assess and develop this architecture - so it connects business requirements with security and regulatory demands.
Scope
Mapping and documenting existing security architecture - networks, data flows, trust boundaries
Maturity assessment against SABSA, NIST CSF 2.0 and TOGAF frameworks
IT network segmentation design (microsegmentation, VLAN, firewall rules)
OT zone and conduit architecture per IEC 62443
Zero Trust model design (NIST SP 800-207) - identity, devices, network, applications
Cloud security architecture (AWS, Azure) - landing zone, guardrails, IAM
Governance - roles, responsibilities, policies and decision frameworks
Architecture documentation and configuration standards - so the team can independently maintain and develop the architecture
Process
Discovery
We map the existing architecture: networks, systems, data flows, dependencies.
Requirements
We define security requirements based on risk analysis, regulations, and business objectives.
Architecture design
We create the reference architecture: segmentation, access control, monitoring, resilience.
Validation
We verify the design with IT/OT teams and test key assumptions.
Implementation and documentation
We support implementation and deliver architectural documentation and configuration standards.
Case study
Critical infrastructure operator
We designed a security architecture covering IT and OT network segmentation, DMZ zones, and an access control model for a multi-site organisation.
The organisation implemented a coherent security architecture that meets regulatory and IEC 62443 requirements.

FAQ
How does a security architect differ from an audit? +
An audit assesses the current state. A security architect designs the target state - creating a plan for how the infrastructure should look and which protection mechanisms to apply.
Do you design architecture for hybrid environments (on-premises + cloud)? +
Yes - we design coherent architectures spanning on-premises infrastructure, cloud (AWS, Azure, GCP), and OT environments. The key is a consistent security policy regardless of where assets reside.
How long does a security architecture project take? +
A typical project takes 4 to 12 weeks, depending on environment complexity and scope (e.g., IT network only vs. full IT+OT+cloud).
Do we need new tools and solutions? +
Not always - we often optimise the use of existing infrastructure. We recommend new solutions only when justified and always considering the budget.
How does the collaboration with our IT team work? +
We work closely with the client's teams - the architecture must be deployable and manageable by the internal team. We document decisions and train on new solutions.
How does SEQRED price its services? +
Pricing is based on an individual estimate of our consultants' time, considering the project scope and complexity. We present the offer broken down by phases - so you see exactly what you're paying for and can make decisions at each stage.
Can I speak with an expert before making a decision? +
Yes - an initial consultation is always welcome and free of charge. We help define the actual scope of your needs, which allows us to prepare a rational offer tailored to your organization.
What determines the cost of a security architect service? +
Pricing is shaped by the project type - migration, new investment, or modernization - and the regulatory and compliance requirements that need to be reflected in the architecture.
We'll discuss scope, methodology, and timeline.
Free consultation, no strings attached.
