Enterprise security architecture consulting

Enterprise security architecture is the documented design of how security capabilities protect an organization's systems: which controls exist, where they sit on each component and connection, and how they map to the business processes the systems serve. The working artifact is an architecture diagram with data flows and control placement, kept current as systems change.

A review examines one system or platform in depth: its components, connections and the controls on each, producing ranked findings and fixes. An assessment measures the architecture function across the organization against the security capabilities and produces a maturity view with a target state and roadmap. A review answers whether this system is designed securely. An assessment answers whether security is designed into how the organization builds.

Two pricing forms. Advisory is billed at USD $250 an hour in bundles of 10, 40 or 100 hours, with the larger bundles discounted, and the same rate applies inside a fractional security team retainer. Reviews and assessments are quoted as a fixed fee after the scoping call: a single-system security architecture review typically falls between USD $9,000 and $25,000, and a target-state assessment across several platforms is scoped above that. The price follows the number of components and connections in scope, how much of the architecture is already documented, and whether our team also builds the design. The scoping call is free and ends with a written quote.

Four stages. Discovery first: interviews with the people who know the system from a technical and a business-value point of view, a read of existing diagrams and documentation, and technical discovery with scripts or tooling where documentation is thin. Then the walk: every component checked for hardening, patching, endpoint protection and privileged access, every connection checked for authentication, encryption and logging. Then design: ranked findings with a fix each, a target architecture, and the SOC 2 and ISO 27001 mapping. Then handoff to your engineers and security operations. A single-system review is measured in weeks and a multi-platform target-state assessment in months; the scoping call sets the timeline for your system.

Five things. A senior architect doing the work, with ten or more years in cybersecurity, five in architecture, and credentials such as CISSP or CCSP. A documented method that walks components and connections rather than a slide of tools. Deliverables engineers can build from: diagrams with data flows, control placement and written requirements. A handoff to security operations, so logs, detection use cases and compliance evidence come from the finished design. And independence from the technology vendors whose products the design places. Ask any firm you evaluate for a sample diagram and a sample findings page before you sign.

Access to the people who know the system, an executive who owns the risk decisions the design will raise, and whatever documentation exists: diagrams, data-flow descriptions, cloud account layouts, the list of security tools in place. A current diagram helps and is optional; when none exists, producing it is the first deliverable. Read-only access to cloud consoles or network observation is arranged during discovery when technical discovery is needed, and Truvo takes no custody of production data.

Accountability rests with the senior technology or security leader, typically the CTO or CISO, regardless of who provides the advice. The advising security architect, whether in-house, fractional or consulting, designs and reviews. The accountable executive decides and owns the risk the design accepts.

A typical bar is ten or more years of cybersecurity experience with at least five in security architecture, supported by certifications such as CISSP, CCSP, CISA, CISM or GIAC. Beyond credentials, the consultant needs a working understanding of the technology being secured, the business processes it serves, and what security operations requires to run the system day to day.

At the first of: a compliance requirement with system implications (SOC 2, ISO 27001, a customer security review), a new platform build or cloud migration, or the first serious security technology deployment such as EDR or SIEM. Advice before these moments decides the design. Advice after them audits it, and redesign costs more than design.

No. Vendor solution engineers know their product's reference architecture better than anyone, and their hours are already paid for. Our role is independent: whether the product is the right control at all, where it sits in the wider design, and whether its telemetry reaches your security operations team.
