Security Architecture
Design of the security controls built into your systems: identity, network segmentation, encryption, logging and trust boundaries, documented so engineering teams can build to them.
Capability overview
What security architecture involves
Security architecture decides how controls fit together before anything is built or bought. We define trust boundaries, how users and services prove who they are, where data is encrypted and which events must be logged, so security is part of the design rather than a review at the end.
Designs follow zero trust principles described in NIST SP 800-207 and are written as reusable patterns: a standard for internet-facing applications, one for internal services, one for third-party connections. New projects then start from an approved pattern instead of a blank page.
What is included
What the work produces
Reference architectures
Diagrams and written standards for common system types, covering identity, network placement, secrets handling, encryption and log forwarding.
Threat models
STRIDE-based analysis of key systems that records the threats considered, the controls chosen and the risks consciously accepted.
Segmentation design
Network and account boundaries that limit how far an attacker can move after compromising a single laptop, server or cloud workload.
Architecture review service
A lightweight review gate for new projects, with turnaround measured in days so security does not become a delivery bottleneck.
How we work
How we deliver security architecture
Current design capture
Existing diagrams, cloud configurations and data flows collected and corrected, because documentation rarely matches what is deployed.
Principles and standards
A short set of architecture principles agreed with engineering leads, such as no shared admin accounts and encryption for all data in transit.
Pattern design
Reference designs drafted for the most common workloads and tested against realistic attack paths.
Validation with builders
Patterns walked through with the teams who will implement them, adjusted where they are impractical or too costly.
Governance setup
Exceptions process and review cadence put in place so the architecture stays current as platforms change.

Security Assessment & Auditing
Structured audits of your security controls against a named standard such as ISO/IEC 27001, the CIS Controls or sector regulations, with evidence-backed findings and a remediation plan.
Vulnerability Assessment
Authenticated scanning of servers, endpoints, network devices and web applications to find known weaknesses, ranked by real exploitability rather than raw severity scores.
Penetration Testing
Manual, intelligence-led attacks on your applications, networks and cloud accounts by testers who chain weaknesses together to show what a real attacker could reach.
Web Application Security
Protection for live websites and web applications: hardened configuration, a tuned web application firewall, bot and abuse controls, and fixes for OWASP Top 10 weaknesses in production.

Ask a questionNo. Much of the work is retrofitting controls to existing estates, for example introducing segmentation into a flat network or moving legacy applications behind single sign-on.
Zero trust guidance in NIST SP 800-207, the CIS Controls and cloud provider well-architected security pillars are the usual references. Where you already follow ISO 27001, designs map to its Annex A controls.
A penetration test finds weaknesses in something already built. Security architecture decides how it should be built so that whole classes of those weaknesses never appear.
