Starting prices for a typical small business. Your final fixed quote follows a free 30-minute discovery call. AI consulting can be combined with fractional vCISO or compliance work.
Market ranges are published 2026 figures for U.S. AI consulting. Most sources are consulting firms that publish their own observed rates, so treat them as directional, not as a price list.

Nexus Security Advisors helps Israeli startups and scale-ups pass U.S. security reviews, earn SOC 2, align with U.S. privacy laws, and put a named, U.S.-based fractional CISO in front of customers, investors, and boards.
Israeli startups build world-class technology, but U.S. enterprise deals often stall on security and compliance, not features. These are the questions your U.S. buyers, partners, and investors will ask.
Many U.S. enterprises won't sign without a SOC 2 Type II report, a recent penetration test letter, and current security policies.
SIG, CAIQ, and custom vendor questionnaires arrive with every deal. Slow or inconsistent answers cost weeks.
California's CCPA/CPRA and a growing list of state laws, plus sector rules such as HIPAA for health data and the FTC Safeguards Rule for financial data.
Buyers want a named, accountable security leader they can talk to in their time zone, not a contact eight time zones away.
AI products now face questions on model risk, data use, and the NIST AI RMF, ISO/IEC 42001, and the EU AI Act.
Selling to U.S. government or defense primes brings FedRAMP, CMMC, and NIST SP 800-171 requirements.
We serve as your security leader for U.S. customers: joining security review calls, owning questionnaire responses, and speaking to your program with credibility.
We build a reusable answer library, security overview, and trust page so sales can respond in days, not weeks.
Scoping, policies, control implementation with your team, evidence, and help selecting a U.S. CPA firm and penetration tester.
We map your program under Israel's Privacy Protection Law and GDPR to U.S. state privacy and sector requirements, working alongside your counsel.
Clear cyber risk metrics for U.S. investors and boards, and due-diligence support for funding rounds and acquisitions.
An incident response plan that covers U.S. breach-notification and customer-contract obligations, tested with an executive tabletop exercise.

Expanding into the U.S. this year? Tell us about your product, customers, and timeline, and we'll reply within one business day with a practical starting point.
Request a consultationYes. As your fractional CISO, we can be the named security leader on security reviews, questionnaires, and customer calls, and we report to your founders and board. We are a U.S.-based firm working in U.S. business hours.
Often, yes. Many U.S. enterprise buyers ask for a SOC 2 Type II report specifically. The controls overlap heavily, so an existing ISO 27001 program shortens the path; we map what you have and close the gaps.
A SOC 2 Type I report reflects a single point in time and can follow a few months of readiness work. A Type II report covers an observation period, commonly three to twelve months, so it pays to start early. We help you sequence both against your sales pipeline.
That is a legal and tax decision for your attorneys and accountants. We coordinate with them so your security program, SOC 2 scope, and contracts cover the right entities, which is a common source of delays in U.S. deals.
Israel is usually seven hours ahead of U.S. Eastern Time. We schedule working sessions in the U.S. morning, which is the Israeli afternoon, and keep asynchronous updates moving across the Sunday-to-Thursday Israeli work week.
No. We provide security and compliance leadership. For questions about law, contracts, or corporate structure, we work alongside your legal counsel.
Most small and mid-sized businesses need CISO-level judgment long before they can justify a full-time, six-figure security executive. A fractional or virtual CISO gives you that leadership on a schedule and budget that fits.
Plain-English status on the regulations our clients ask about most, with key dates, what to do next, and links to the official sources.
The CRA sets mandatory cybersecurity requirements for “products with digital elements” (hardware and software) sold in the EU, across their whole lifecycle. It applies to manufacturers, importers, and distributors, including U.S. companies selling into the EU. Fines reach up to €15 million or 2.5% of worldwide annual turnover.
On July 13, 2026, the Department of War paused Phase 2, which would have made third-party (C3PAO) Level 2 certification the default for many contracts starting November 10, 2026. It also launched a 60-day CMMC Reform Task Force and a public request for information. As of late October 2026, no resumption date has been announced. The 32 CFR Part 170 rule itself remains on the books.
Our view: the pause is a window to get audit-ready, not a reason to stop. Requirements can return quickly.
The current HIPAA Security Rule remains in force. HHS proposed the first major update in two decades (published January 6, 2025). The federal regulatory agenda now lists final action no earlier than mid-2027, and agenda dates are not binding.
Smart move: adopt HHS 405(d) Health Industry Cybersecurity Practices now; they line up with where the rule is heading.
Version 4.0.1 is the active standard for anyone who stores, processes, or transmits cardholder data. The “future-dated” requirements introduced in v4.0 became mandatory on March 31, 2025, so assessments now test all of them.
The RMF is the seven-step process federal agencies and many contractors use to manage security and privacy risk across a system's lifecycle. Click a step:
Last reviewed October 23, 2026. This summary is general information, not legal advice; confirm requirements against the official sources.
Every finding gets a plain-language title, a business impact, a named owner, a due date, and a retest date. Have the plan in place, then work the plan.
Timelines are illustrative and scale with organization size and scope.
Measures are selected using NIST SP 800-55 guidance and reported as trends, not one-off snapshots.
Our methods draw on established, peer-reviewed and consensus standards, so results are repeatable and defensible to auditors, boards, and regulators:
Every risk is scored the same way, assigned an owner, and given a deadline. Try it: pick a square on the matrix.
Pick a scenario, then switch controls on and off to see how inherent risk becomes residual risk.
Illustrative model for discussion: control effects are simplified. Real assessments use your environment, evidence, and threat data.
Example scoring. Thresholds and deadlines are tailored to each client's risk appetite.

A fractional or virtual CISO is a senior security executive who leads your security program part-time. You get CISO-level strategy, risk management, and board reporting without the cost of a full-time hire.
Small and mid-sized businesses in any industry, including financial services, healthcare, defense suppliers, manufacturing, technology, and professional services, that need executive security leadership, are facing an audit or assessment, or are rolling out AI and need it governed.
Yes. We assess your current state against NIST SP 800-171 and CMMC requirements, identify gaps, and build a prioritized, owner-assigned plan to close them.
We start by finding the AI tools and agents actually in use, then build AI risk into each initiative's business case, apply least privilege to AI agents, and align to frameworks such as NIST AI RMF, ISO/IEC 42001, the EU AI Act, and the OWASP AI Exchange.
Yes. We are happy to sign a mutual NDA before any detailed discussion of your environment.
No. We provide security leadership and oversight and work alongside your IT team or managed service provider, helping them prioritize and measure what matters.
Usually as a predictable monthly retainer sized to your needs, or a fixed fee for project work such as an assessment or readiness sprint. We recommend an option after the free discovery call.
