IT & Security for Financial Firms
Financial firms live on confidentiality, which is why you will not find one of our financial clients named anywhere on this site. NetSys serves hedge funds, investment advisers and accounting practices through vCISO leadership and cybersecurity consulting: the security program written down, the controls implemented and evidenced, and the questionnaires answered truthfully. The work is real. The names stay private. In this industry, that discretion is the first thing worth proving. Accounting and CPA practices have particular pressures, filing seasons, client financial identities, written information security plans, and those are covered on our dedicated accounting page.
The short answer
NetSys provides cybersecurity services and IT support to financial firms — principally CPA and accounting practices and hedge funds — primarily through vCISO leadership and cybersecurity consulting. That covers security strategy and roadmap, risk and compliance assessments, written policies and governance aligned to the rules your firm answers to, cyber-insurance readiness, vendor and third-party risk oversight, incident-response and disaster-recovery planning, and executive or board-level reporting. Where a firm wants one partner for both, it also covers the underlying stack: multi-factor authentication and identity hardening, email protection against wire fraud and business email compromise, managed endpoint detection and response, and immutable backups with scheduled restore tests. We implement, document, and evidence controls; interpreting the rules and deciding what gets filed stays with your compliance counsel. Client identities are withheld by design, so this page carries no named case studies.

Financial Services IT FAQs
Why are there no case studies on this page?
Because our financial clients — mostly CPA firms and hedge funds — engage us under confidentiality, and we honor that in our marketing, not just our contracts. We'd rather show no case study than publish an invented one. Where a reference is essential, we arrange it privately with a client's consent.
What do you actually do for hedge funds and CPA firms?
Mostly vCISO work and cybersecurity consulting: security strategy and roadmap, risk and compliance assessments, written policies, cyber-insurance readiness, vendor and third-party risk oversight, incident-response and disaster-recovery planning, and board-level reporting — plus the underlying security stack (MFA, EDR, email protection, tested backups) where the firm wants one partner for both.
Can you help with investor and client due-diligence questionnaires?
Yes — vendor and third-party risk oversight and questionnaire support are part of the vCISO program. The goal is that every answer your firm gives is truthfully 'yes' and backed by documentation, which is also exactly what protects you at insurance-claim time.
Do you replace our IT provider?
Not necessarily. Financial firms often bring us in as the security layer — vCISO leadership and cybersecurity consulting — alongside an existing IT provider or internal staff. If you'd rather consolidate, our managed IT practice handles the full environment.
Do you work with accounting and CPA firms as well as funds?
Yes — accounting and CPA practices are one of the two financial audiences we serve, alongside hedge funds and investment advisers. Their exposure is specific enough to warrant its own page: a complete financial identity for every client on the list, returns and payment instructions moving by email, and a filing season during which downtime is not survivable. Our accounting industry page covers that work in detail.
What is a vCISO for a financial firm, and do we need one full-time?
A vCISO is executive security leadership as a service: someone who owns the security program, writes the policies, runs the risk assessments, sets the roadmap and the security budget, and answers to your partners, your investors, and your insurer. A firm can need that judgment on a regular cadence without needing a full-time security executive on the payroll. Our vCISO service runs on a standing monthly or quarterly leadership cadence, plus as-needed sessions when an exam, an insurance renewal, an incident, or an investor question lands.
Can you help with SEC Reg S-P and examination readiness?
We build and document the controls the rules ask for — incident response with defined notification steps, access control, encryption, vendor and third-party oversight, written policies, and evidence that all of it is actually in place — and we keep that documentation in a state where it can be handed over rather than reconstructed under pressure. Interpreting the rule and deciding what your firm has to file stays with your compliance counsel or consultant. What we hand you is the control set, the evidence, and answers your firm can stand behind.
How do you stop wire fraud and business email compromise?
In layers, because no single control does it. Multi-factor authentication and conditional access, so a stolen password is not enough on its own. Email threat protection tuned for lookalike domains and reply-chain hijacking. Alerting on inbox rules that quietly forward or delete mail. Then the part that is not technology: an out-of-band callback procedure for any change to payment instructions, written down and enforced no matter who appears to be asking — including on a video call.
We are a small firm with no IT staff. Is a vCISO overkill?
Usually the opposite. Small firms receive the same security questionnaires from custodians and institutional clients that large ones do, often with nobody whose job it is to answer them. If you have no IT staff at all, we can run the environment and the security program together. If you already have an IT provider you like, we come in as the security layer alongside them. Either way it is month to month — no long-term contract, on any NetSys agreement.
Do you offer the free external penetration test to financial firms?
Yes, and it is the fastest way to find out whether your current setup holds. An engineer comes to your office, demonstrates how far an attacker actually gets, and leaves a prioritized fix list. You keep the findings whether or not you hire us. For a firm that needs to show an insurer or an institutional client that testing happens, it is also a sensible place to start.
