Financial Services Solution Stack
The exact technical stack Petronella Technology Group deploys for RIAs, broker-dealers, community banks, credit unions, CPAs, wealth managers, and insurance practices. WORM communication archival, supervision queue tooling, NYDFS 23 NYCRR 500 control mapping, GLBA Safeguards program documentation, and pre-staged forensic readiness for securities examiners. Every component, every SLA, every audit deliverable.
The WORM Communication Supervision Stack.
The headline deliverable for any FINRA, SEC, or NAIC-regulated firm is the integrated capture-supervise-retain-produce architecture for electronic communications. Petronella deploys it as a five-layer stack with named vendor categories at each layer. Vendors listed below are example integrations, not endorsements. The actual stack we deploy in your environment is a function of your existing Microsoft 365 or Google Workspace footprint, your custodian or core processor relationships, your examination cadence, and your retention obligations.
WORM Communication Supervision Stack
Five integrated layers that together satisfy FINRA Rule 4511, SEC Rule 17a-4 (and the 2022 audit-trail-alternative amendment), state DOI cyber rules, and the NAIC Insurance Data Security Model Law. Components are deployed, documented, and produced as audit evidence on demand.
Capture
Multi-Channel Source Capture
Email (Microsoft 365 or Google Workspace journaling), Microsoft Teams chat and meeting transcripts, Bloomberg messaging, Slack Enterprise Grid, signed Signal/WhatsApp captures, SMS via approved phone-system gateway, and voice-to-text from approved recorded phone lines.
Integration examples: Microsoft 365 journaling rule, Teams Export API, Smarsh Capture, Theta Lake. Capture rule set is documented per channel and reviewed quarterly.
WORM Archival
Non-Rewriteable Storage with Retention Lock
All captured content lands in a write-once-read-many archive with vendor-attested storage immutability, audit logging of every read, hash-based tamper detection, and a third-party-downloader attestation letter on file with the SEC.
Vendor categories: WORM-archival vendors like Global Relay, Smarsh Enterprise Archive, or Mimecast Cloud Archive (selection driven by your custodian or examiner preference). Retention windows configured to FINRA 4511 6-year minimum, SEC 17a-4 3-year quick-retrieval, with longer windows on a per-record-class basis.
Supervision
Supervisory Queue and Principal Review
Lexicon-based and AI-assisted flagging across the captured corpus, configurable to your written supervisory procedures. Designated principals review flagged items, document disposition, and produce a per-period supervisory log. Off-channel detection (text from a personal phone, Signal mention in an email body, off-system file shares) flags for compliance review and triggers your remediation workflow.
Integration examples: Smarsh Enterprise Supervision, Global Relay Supervision, Microsoft Purview Communication Compliance, Theta Lake. Lexicon and disposition tracking is deliverable as evidence in any FINRA exam.
Retention & Hold
Lifecycle Management with Litigation Hold
Per-channel, per-record-class retention schedules tied to regulatory minimums. Legal-hold workflow that suspends deletion across the archive when triggered by counsel. Defensible deletion at end of retention period with audit log. Cross-archive search to satisfy regulator subpoena or litigation discovery.
Designed to survive an actual subpoena. Hold workflow rehearsed annually as part of incident-response exercise.
Production & Audit Export
Examiner-Ready Production Workflow
One-click export of supervisory logs, captured corpus subsets, retention attestation, third-party-downloader letter, and audit-trail-alternative documentation (per the October 2022 SEC 17a-4 amendment). Production formats compatible with SEC, FINRA, state DOI, and FFIEC examiner request templates.
Production workflow tested quarterly with a mock examiner request. Time from request to delivery: documented under 72 hours for standard scopes, under 5 business days for full firm-history production.
Control mapping deliverable for the New York cybersecurity regulation.
If you write business in New York or your carrier requires NYDFS 500 attestation, this is the control implementation matrix Petronella ships. Each row maps the NYDFS section to the technical control we deploy, the vendor or integration category, and the audit evidence we produce. Delivered as a signed PDF, an editable spreadsheet, and a quarterly attestation refresh.

The Written Information Security Program (WISP) deliverable.
Under the FTC Safeguards Rule (2023 amendments), every covered financial institution (now broadly including CPAs, mortgage brokers, tax preparers, and many more) must maintain a written information security program with nine prescribed elements. Petronella ships the WISP as a complete program package, not a downloaded template.
Written Information Security Plan
50-to-80 page WISP covering all nine FTC Safeguards elements. Tailored to your firm size, services, and customer-information inventory. Signed by the qualified individual (Petronella as service-of-record, or your in-house designee with our advisory support).
Risk Assessment Workbook
Threat-source-by-asset risk register with likelihood, impact, inherent risk, controls in place, residual risk, and treatment decision. Refreshed annually, with material-change triggers documented inline.
Qualified Individual Designation
Letter of designation naming the qualified individual responsible for the program. Petronella can serve in this role under written agreement, or support your in-house designee.
Employee Training Program
Role-based training curriculum, annual mandatory completion, phishing simulation outcomes, training-platform export evidence. Petronella runs the program or hands it to your HR partner with full documentation.
Vendor Management Register
Inventory of every third party with access to customer information, due-diligence file per vendor, contractual security requirements, periodic reassessment cadence, exit-and-recovery plan per critical vendor.
Board (or Sole-Prop) Annual Cyber Report
Annual written report from the qualified individual to the board or governing body covering material risks, incidents, control effectiveness, and recommended program changes. Required under FTC Safeguards 314.4(i).
PAM session recording for treasury, FedLine, and core access.
For firms with FedLine wholesale-payments access, core-banking administration, or wire-treasury workflows, the privileged-access management layer is the difference between an examiner observation and an MRA. Petronella deploys a PAM solution with session recording, just-in-time elevation, vaulted credentials, and a tamper-evident replay log for any privileged session.
Privileged Access Management Stack
Designed for the financial services privileged-access threat model: insider abuse, account compromise, and the post-incident need to reconstruct exactly what a privileged user did, when, and against which target system.
Encrypted Credential Vault
All privileged credentials (FedLine, core admin, hypervisor, network gear, custodian portals) checked into an encrypted vault with rotation policy, break-glass procedure, and access-request workflow.
Just-in-Time Privilege Granting
Privileges granted only at moment of need, for the minimum duration, against the minimum scope. Time-bound elevation with automatic deprovisioning. Approval workflow for sensitive scopes.
Full-Session Capture and Replay
Every privileged session recorded as searchable video and command-log. Replay available for audit, incident reconstruction, or examiner production. Tamper-evident storage with hash chain.
Phishing-Resistant Authentication
FIDO2 hardware keys (YubiKey or equivalent) for every privileged-access credential request. No phishable factor, no SMS, no TOTP. Backed by recovery procedure with dual-control approval.
Real-Time Anomaly Detection
Every PAM event streams to the SIEM with correlation rules tuned for financial-services privileged-access threat patterns: after-hours treasury access, novel-IP FedLine connection, batch-anomaly ACH origination, multi-target credential harvesting.
Pre-staged evidence collection for securities and banking examiners.
When an SEC, FINRA, FFIEC, or state DOI examiner shows up after an incident, the question is not whether you have logs. It is whether you have the right logs, in a defensible chain of custody, with attribution that survives expert challenge. Petronella pre-stages this so that on day one of an incident, the evidence collection runs from a documented runbook rather than from improvisation.
Pre-Stage
Forensic data sources identified, log sources confirmed, retention windows mapped to source, evidence-collection runbook written, chain-of-custody templates loaded, on-call escalation tree current.
Trigger
SIEM alert, vendor notification, employee report, or examiner request triggers the IR plan. Petronella IR engineer paged, initial scope decision within 30 minutes, counsel and senior management notified per workflow.
Evidence Collection
Forensic image of affected endpoints (write-blocked, hashed, dual-witnessed). Memory capture if scope warrants. Cloud-tenant log preservation. Mailbox audit logs frozen. Network metadata pulled. All collected per runbook with chain-of-custody documentation.
Examiner Production
Evidence package assembled per regulator request format. Chain-of-custody documentation, hash manifests, attribution analysis, timeline reconstruction. Craig Petronella (NC Licensed Digital Forensics Examiner #604180) signs as forensic examiner of record where required.
