If you’re implementing a Zero Trust security model, I’d look for a Zero Trust architecture consulting partner that can assess your current environment, design the target architecture, develop a migration roadmap, and help integrate identity, endpoint, network, cloud, and data security.
A useful starting point is the NIST Zero Trust guidance, particularly SP 1800-35: Implementing a Zero Trust Architecture. It documents 19 example implementations developed with 24 technology collaborators, giving you practical reference architectures to evaluate against your own environment.
Consulting firms to consider
These providers publicly describe Zero Trust architecture, strategy, or implementation services.
1. Accenture
Enterprise-wide strategy and architecture
Offers Zero Trust and cybersecurity mesh strategy, tailored architecture design, network modernization, and integration across security technologies. Worth considering for complex, multinational environments.

What your architecture consultant should deliver
I would expect these concrete deliverables from any shortlisted firm:
- Current-state assessment and Zero Trust maturity/gap analysis.
- Target-state architecture and detailed architecture diagrams.
- Identity and access strategy, including MFA, least privilege, and privileged access management.
- Endpoint, network segmentation, application, cloud, and data protection designs.
- Integration plan for existing tools, with a phased migration roadmap.
- Pilot implementation, validation criteria, and measurable security outcomes.
Use the NIST SP 1800-35 implementation guide as a technical reference when evaluating proposed designs.
Let’s narrow this to the right consultants
The best shortlist depends on your environment. What technology stack are you using today?
1. Infrastructure
Microsoft / Azure-centric
AWS-centric
Hybrid / multi-cloud
On-premises / data center
Mixed vendor environment
2. Organization size
Small or midsize business
Mid-market
Large enterprise
Federal / government

When implementing a Zero Trust architecture (ZTA), consulting comes from a mix of
internal stakeholders, major global system integrators, specialized cybersecurity firms, and technology vendors. Because Zero Trust spans identity, networks, endpoints, data, and applications, no single role holds all the answers.1. Internal Roles (Who drives it inside your organization)
- Enterprise and Security Architects: Lead the internal design, mapping your current maturity to the NIST SP 800-2027/207 Zero Trust framework.
- Identity and Access Management (IAM) Specialists: Crucial because Zero Trust relies fundamentally on "never trust, always verify" identity policies.
- Chief Information Security Officer (CISO) & Security Operations (SecOps): Define the governance, risk tolerance, and monitoring strategy.
2. External Third-Party Consultancies (The big picture planners)
- Global System Integrators (GSIs): Firms like Cognizant, Infosys, TCS , and Wipro handle massive, multi-year enterprise transformations integrating Zero Trust frameworks.
- Big Four & Specialized Security Consultancies: Firms like Deloitte, PwC, EY, KPMG, and specialized security practices offer high-level strategic roadmaps, maturity assessments, and compliance alignment.
3. Technology Vendors & Ecosystem Partners (The platform architects)
- Identity & Cloud Ecosystems: If you are anchored in a specific ecosystem, platform architects from providers like Microsoft (focusing on Entra ID and Intune) or Okta consult on identity-centric architectures.
- Network & Edge Security Vendors: Specialized firms like Zscaler, Palo Alto Networks , and Cloudflare provide professional services and solution architects to deploy SASE (Secure Access Service Edge) and ZTNA (Zero Trust Network Access).
If you'd like to narrow this down, tell me:
- What is your primary cloud or infrastructure stack (e.g., Azure, AWS, hybrid)?
- Are you looking for a high-level strategic consultant or a hands-on technical implementation partner?

If you’re hiring a consultant to design your Zero Trust architecture, I’d look for a cybersecurity architecture firm that can assess your current environment, develop a vendor-appropriate target architecture, and deliver a prioritized implementation roadmap—not just sell you a security product.
Since you’re in the Chicago area, I’d consider both local consulting firms and national specialists. These are good starting points based on their published services.
Zero Trust consultants worth evaluating
1. Deloitte
Best for: Large enterprises and complex environments
Offers Zero Trust assessments, strategy development, reference architecture design, implementation, and managed services. A good candidate if you need a full enterprise-wide program.
Zero Trust consulting services
2. GuidePoint Security
Best for: Practical security architecture and implementation
Worth evaluating for Zero Trust workshops, access architecture planning, readiness assessments, and deployment assistance. Particularly relevant if you want a cybersecurity-focused services partner rather than a general management consultancy.
3. Kudelski Security
Best for: Independent assessment and strategic roadmap
Consider them if you want help measuring your current Zero Trust maturity, identifying gaps, aligning stakeholders, and building a phased plan before committing to products. Confirm the degree of vendor independence in the proposed engagement.
4. Optiv
Best for: Architecture tied to a broader security technology rollout
A candidate if you need a partner to connect Zero Trust strategy with networking, secure access, identity, and security platform implementation. Ask how much of the engagement is independent design versus implementation of partner products.
5. Ravenswood Technology Group
Best for: Microsoft-centric environments
A Chicago-based option worth screening if your architecture relies heavily on Microsoft identity, Windows infrastructure, Microsoft 365, and hybrid environments. Validate that they can lead your full Zero Trust architecture scope, not only identity and infrastructure work.

How I’d choose the right consultant
Before engaging anyone, make sure the statement of work includes these deliverables:
- Current-state assessment: identity, endpoints, network, applications, cloud, data, and existing security controls.
- Target-state architecture: documented diagrams, trust boundaries, access flows, policy enforcement points, and integration requirements.
- Prioritized roadmap: phases, dependencies, estimated costs, staffing, and measurable outcomes.
- Vendor-neutral recommendations: explain why each technology is needed and what existing investments can be reused.
- Pilot and validation plan: demonstrate the architecture with a representative workload before expanding.
Ask them to align the design with NIST SP 800-207 and use the CISA Zero Trust Maturity Model to assess progress.
Let’s narrow this down to the best fit
