What we deliver.
Starting prices come from our live catalog. Your proposal fixes the tier and price before anything is signed.
CISO Comprehensive Security Assessment
Holistic evaluation of your organization's entire security program across all critical domains. This efficient, structured assessment provides CISOs and security leaders with a complete diagnostic of security capabilities, maturity gaps, and prioritized improvement opportunities. Our comprehensive approach delivers actionable insights across governance, technical controls, and operational security to inform strategic decision-making and resource allocation.
Board & Executive Cyber Risk Education Program
Specialized education program designed to help boards of directors and executive teams understand, govern, and communicate about cybersecurity risks and their fiduciary responsibilities. Our expert-led program addresses the growing regulatory requirements for cyber risk oversight, SEC disclosure obligations, and provides practical frameworks for effective security governance at the highest organizational levels.
Security Technology Selection Advisory
Vendor-neutral guidance for organizations navigating complex security technology decisions. Our expert advisory service helps security leaders define requirements, evaluate solutions, and select technologies that align with their security strategy and business needs, avoiding costly procurement mistakes and ensuring optimal return on security investments.
Zero Trust Security Assessment
Comprehensive evaluation of your organization's zero trust architecture implementation, examining identity verification, network segmentation, and access controls. Our assessment identifies gaps in your zero trust strategy and provides a roadmap for enhancing security beyond traditional perimeter-based approaches.
Phase 0 — Enterprise AI Risk Assessment
The six pillars of the AI security program are not sold off a shelf — they are built into your ecosystem, and that requires knowing the ecosystem first. Phase 0 is a scoped, fixed-fee assessment that maps your environment end to end: every AI system in use (sanctioned and shadow), the DevSecOps reality, the data and identity stack, the SIEM / EDR / tooling landscape, and where testing should start. It defines how each pillar gets built for you (BYOK and open-source first, commercial upgrades where they earn their place), designs the integration seams into what you already run, and plans the deployment topology for distributed sites. The output is the current-state map, the future-state design and a sequenced build plan — and only then does the program get a number. CISO Marketplace members get the Phase 0 fee credited toward the program if they proceed.
Virtual & Fractional CISO Services
Expert security leadership for organizations that need executive-level cybersecurity guidance without the cost of a full-time CISO. Our Virtual/Fractional CISO service provides experienced security executives who integrate with your team to develop and manage your security program, guide strategic initiatives, communicate with your board, and ensure security aligns with business objectives.
Continuous Security Validation Service
Subscription-based ongoing testing of your security controls, detection capabilities, and response procedures against real-world attack techniques. Our continuous validation approach provides evidence-based assessment of security effectiveness beyond traditional point-in-time assessments, ensuring your defenses work as expected against evolving threats.
Data Protection & Compliance Officer Advisory Services
Specialized advisory service providing organizations with expert Data Protection Officer (DPO) and/or Chief Compliance Officer (CCO) capabilities without the overhead of full-time executive hires. Our experienced professionals serve as your designated privacy and compliance leadership, fulfilling regulatory requirements while implementing effective data protection and compliance programs tailored to your organization's specific needs.
Sr Engineer-as-a-Service Subscription
Access to senior-level engineering expertise on a subscription basis for cybersecurity implementation and support.
Attack Surface Management Program
Continuous discovery, monitoring, and assessment of your organization's external attack surface and digital footprint. Our ongoing service provides real-time visibility into internet-exposed assets, shadow IT, misconfigurations, and newly emerging vulnerabilities, enabling proactive risk reduction before attackers can exploit these weaknesses.
CCO-as-a-Service Subscription
Outsourced Chief Compliance Officer service providing ongoing compliance management and governance support.

CISO & CCO Executive Training and Life Coaching Subscription
Executive-level training and coaching services for Chief Information Security Officers and Chief Compliance Officers, including leadership development.
SMB Continuous Security
Ongoing security monitoring and assessment program.
Security Questionnaire & RFP Response Service
Every enterprise deal arrives with a security questionnaire — SIG, CAIQ, a customer spreadsheet or an RFP security section. We build your answer library from your real controls, complete questionnaires inside an agreed turnaround, have a CISO review every submission, and stand up a trust center so many requests never need a questionnaire at all. AI-assisted drafting keeps it fast; a named practitioner keeps it accurate.
Managed Security Awareness & Phishing Simulation
Buying an awareness platform is easy; running it well every month is what nobody has time for. We run the whole program on the platform of your choice: monthly phishing simulations written against current lures, targeted training for repeat clickers, new-hire onboarding, and the metrics your auditor and insurer ask for — reviewed by a CISO, not just scheduled by a tool.
Non-Human & Machine Identity Security
Assess and govern non-human identities — secrets, API keys, service accounts, workload identities, and AI agent identities — covering issuance, rotation, least-privilege, and lifecycle.
Private Equity Portfolio Cyber Oversight Program
Sponsors carry cyber risk across every platform and add-on they own, usually with no consistent view of it. This program gives the fund a portfolio CISO: a common baseline assessment for each company, quarterly scorecards for operating partners and LPs, pre-close cyber diligence on new deals, 100-day plans after close and incident escalation support. Priced per portfolio after scoping — the number of companies, their size and the diligence cadence drive it.
Identity Threat Detection & Response (ITDR)
Identity-centric threat detection and response across Active Directory / Entra ID — privilege escalation, lateral movement, account takeover, and identity misconfiguration detection + response playbooks.
Process
How an engagement runs.
- 01
Scoping call
A practitioner, not a salesperson, walks through targets, constraints and what a good outcome looks like for you.
- 02
Proposal & rules of engagement
A fixed-scope proposal with tier, price and deliverables. Rules of engagement, contacts and out-of-bounds systems are agreed in writing.
- 03
Sign, then start
MSA and SOW are signed electronically and the deposit is paid. Only then does testing begin.
- 04
Execution
Testing runs to the agreed plan. Critical findings are escalated as they are found; you don't wait for the report.
- 05
Report & debrief
An executive summary plus technical findings with evidence, reproduction steps and fixes, walked through with your team.
- 06
Retest
Where the tier includes it, we verify your fixes and reissue the report, so auditors and customers see the issues closed.
Timelines are set per engagement in the SOW.

The Revolut Breach Is a Case Study in Confusing Authentication With Authorization
Revolut disclosed customer data to attackers who spoofed a government agency's email domain for five months. The root cause was not weak email security but a workflow that treated a valid domain as proof of a valid request.
