IT That Holds Up to Examiners —
and to Attackers
Financial services and accounting firms concentrate exactly what attackers want: money movement authority, sensitive client financial data, and seasonal deadline pressure that makes staff click things they shouldn't. Business email compromise and wire-fraud schemes target firms like yours specifically — and regulators expect you to have controls in place before something happens, not after.
We build and manage security programs aligned to the frameworks your firm answers to — PCI-DSS, SOC 2, and the cybersecurity expectations of the SEC, FINRA, and state regulators. That means enforced multi-factor authentication, zero-trust access controls, encrypted client data, monitored email with payment-fraud detection, and the documentation trail examiners ask for.
And because deadlines don't wait for IT, you get fast, accountable support with defined SLAs — so a quiet Tuesday in February and the last week of tax season get the same response standard.
What We Deliver
01
PCI-DSS & SOC 2 Alignment
Security controls, audit trails, and documented policies designed to meet PCI-DSS and SOC 2 requirements — maintained continuously, not assembled the week before an audit.
02
Client Financial Data Security
Encrypted storage, access governance, and data loss prevention policies that ensure sensitive client financial data is handled with the discretion your clients expect.
03
Zero-Trust Network Access
Identity-verified, least-privilege access across your network — eliminating implicit trust so only authorized users reach portfolio, tax, and accounting systems.
04
BEC & Wire-Fraud Defense
Advanced email security, payment-redirect detection, and staff training focused on the business email compromise schemes that target financial firms daily.
05
Business Continuity & DR
Defined RPO and RTO targets, tested backups, and failover planning — so a ransomware event or outage doesn't become a missed filing deadline or a client-facing failure.
06
Exam & Audit Readiness
Policies, evidence, and reporting packaged for regulatory exams and client due-diligence questionnaires — answered with documentation, not improvisation.

Frequently Asked Questions
01Can you help us respond to client due-diligence and vendor security questionnaires?
Yes. Because we maintain your security documentation continuously — policies, controls, testing evidence, and incident response plans — due-diligence questionnaires become a fast, factual exercise instead of a scramble. Many of our financial clients win business partly because they can answer these well.
02How do you protect against wire fraud and business email compromise?
Layered controls: phishing-resistant MFA, conditional access policies, advanced email filtering with impersonation detection, blocked auto-forwarding, alerting on suspicious mailbox rules, and staff training with simulated phishing. We also help firms implement out-of-band verification procedures for any payment instruction changes.
03Do you understand SEC, FINRA, and state regulatory expectations?
We build security programs mapped to the frameworks regulators reference — and we produce the documentation and evidence trail examinations request. For formal compliance determinations we work alongside your compliance counsel, with the technical controls and records to back them.
04Can you handle our seasonal crunch periods?
Yes — our SLAs don't relax during tax season or quarter-end. Monitoring catches capacity and performance issues before deadline weeks, and our 24/7 helpdesk means an issue at 9 PM on April 12th gets a response, not a voicemail.
