Industry-tuned solution stacks

How our core stack flexes across niche verticals

Petronella Technology Group runs the same six-capability security stack everywhere — identity, endpoint, network, data, monitoring, recovery. What changes per vertical is the configuration, the scope, the audit evidence we generate, and the architecture pattern we deploy. This page is the build view of the “more industries” catchall: what ships per niche, how the architecture varies, what evidence comes out the other side.

Six core capabilities, twelve niche configurations CMMC RPO #1449 HIPAA, PCI, SOC 2, NIST 800-171, FTC Safeguards, FERPA evidence stacks
The variation framework

One stack, twelve configurations, four architecture patterns

Every Petronella engagement deploys the same six-capability foundation. The vertical-specific work is in three layers above the foundation: which compliance framework drives the configuration, which architecture pattern fits the data sensitivity, and which evidence artifacts we produce for audit. The matrix below is the deliverable view in one frame.

Capability What ships in every engagement How it flexes per vertical
Identity & access Microsoft Entra ID hardening, conditional access, phishing-resistant MFA, privileged access management, lifecycle automation. FERPA scoping for ed-tech; ITAR partition for engineering; PCI-DSS role separation for hospitality and retail; CUI enclave identities for federal-adjacent.
Endpoint & OT Managed EDR/XDR, USB and removable media controls, encrypted disk, application allowlisting, patching SLAs. POS and PMS hardening for hospitality; CAD workstation profile for engineering; imaging and PMS profile for dental; OT segmentation for SMB manufacturers.
Network & perimeter Next-gen firewall, segmentation, Zero Trust Network Access, DNS filtering, jobsite and branch site-to-site. Guest Wi-Fi isolation for hospitality and education; jobsite trailer overlay for construction; multi-property meshes for hospitality groups; vendor-only partner segments for manufacturing.
Data & encryption Email encryption, sensitivity labels, DLP, vaulted credential storage, encrypted backups. WORM-style retention for SaaS audit logs; ePHI handling for dental; cardholder data scope minimization for retail and hospitality; CUI marking automation for engineering.
Monitoring & SOC 24/7 managed SOC, SIEM ingestion, M365/identity/endpoint correlation, AI-assisted triage, hybrid AI + human analyst response. Vertical playbooks: wire-fraud-attempt detection for real estate and construction; PCI-card-test detection for retail; FERPA event escalation for education; ITAR exfil watchlist for engineering.
Recovery & resilience Immutable backups (air-gapped + cloud), tested restore SLAs, incident response runbooks, business continuity templates. Production-line recovery sequencing for manufacturers; PMS-first recovery for hospitality; HIPAA breach-notification timeline for dental; SOC 2 evidence-of-restore tests for SaaS.
Same six-capability foundation, twelve vertical configurations. Detailed bills-of-material are in the per-vertical sections below.
Why this matters at procurement time: when an enterprise customer or a federal prime asks for a control matrix, our standard response is an evidence package mapped to the framework you operate under (NIST 800-171, HIPAA, PCI DSS, SOC 2, FTC Safeguards, FERPA). The capability column above is the same for every client. The right-most column is the vertical-specific evidence we produce.
Per-vertical solution stacks

What ships per niche, in build terms

Each block below describes the deliverable for a specific niche vertical: the controlling compliance framework, the deployment shape, the bill-of-materials, and the audit evidence the client walks away with. These are templates we’ve shipped, not aspirational diagrams.

Engineering firms (ITAR / NIST 800-171 / CMMC variant)

NIST 800-171 / ITAR

For structural, civil, MEP, and ITAR-exposed engineering firms, we deploy a CUI enclave architecture that isolates federal project data from the broader environment.

Complete policy library, automated control evidence dashboard, vendor risk register, observation-period evidence package, auditor-handoff documentation.

Architecture variation patterns

Four reference architectures, twelve niche applications

Across the twelve verticals above, we deploy four reusable architecture patterns. The patterns are fungible: the CUI enclave that satisfies engineering ITAR is the same architecture that satisfies a manufacturer’s CMMC Level 2 requirement. The PCI scope-minimization pattern that protects a hotel is the same one that protects a multi-location retailer. Recognizing the pattern is how we keep delivery consistent and audit evidence portable.

Pattern A: CUI / Sensitive Data Enclave

An identity-and-network-segmented zone for controlled data with logging, exfil monitoring, and FIPS-validated encryption. Used wherever a regulator or contract demands data isolation.

Used in: engineering ITAR, SMB manufacturer CMMC L2, federal-adjacent professional services

Pattern B: PCI Scope Minimization

Tokenize at the edge, isolate the cardholder data environment, push the rest of the network out of scope. Reduces audit cost, brand-standard exposure, and breach blast radius.

Used in: hospitality PMS/POS, retail in-store and DTC, restaurant groups

Pattern C: Email-Trust Hardening

DMARC enforcement, sender authentication, out-of-band verification SOPs for high-value transactions. The single biggest leverage point against wire fraud and BEC across multiple verticals.

Used in: real estate, construction, architecture, dealer F&I, nonprofit grant cycles

Pattern D: Compliance Evidence Stack

Continuous policy library, automated control evidence collection, vendor risk register, and audit-ready reporting. Reusable across HIPAA, SOC 2, FERPA, FTC Safeguards, and state privacy regimes.

Used in: dental HIPAA, SaaS SOC 2, education FERPA, dealer Safeguards, retail state-privacy
Service-level commitments

Frequently asked

FAQ for the build conversation

Can you mix patterns? My business spans two verticals.
Yes. Mixed-vertical engagements are normal. A nonprofit running a federally funded research program gets the nonprofit baseline plus the CUI enclave pattern. An architecture firm with hospitality clients gets email-trust hardening on the office side plus PCI scope minimization where they touch any cardholder flows. The patterns compose cleanly because they share the same six-capability foundation.

Do you deploy in our existing environment or do we have to migrate?
We deploy in your existing environment in nearly every engagement. The variation is in how aggressively we replace specific components. For most clients we keep the existing M365 or Google Workspace tenancy, the existing line-of-business apps, and the existing core infrastructure, and we layer security and compliance controls on top. Migration only happens when the existing platform is actively unsafe or contractually disqualified.
Who owns the audit evidence we generate?
You do. All evidence (policies, control matrices, screenshots, logs, restore-test results, training rosters, BAA libraries, vendor risk registers) lives in storage you control, with copies retained in our delivery system. If you switch providers, the evidence package is yours.
How long does a typical vertical-tuned deployment take?
Range is 30 to 120 days for the initial deployment, depending on the vertical and the starting state. Email-trust hardening (Pattern C) can ship in two to three weeks. A CMMC Level 2 readiness package (Pattern A plus evidence stack) is a 90- to 180-day project before C3PAO scheduling. SOC 2 readiness plus the observation period is 6 to 12 months end to end. We scope the timeline honestly during the first call.
Do you handle the audit itself, or just prep us for it?
We don’t perform the audit (separation of duties matters in every framework we work with). We prepare you for the audit, coordinate with the audit firm of your choice, sit in on auditor interviews when helpful, and produce evidence on demand during the observation period. For CMMC, we’re an RPO not a C3PAO, so the certification assessment is run by an independent third party.
What if our compliance posture sits between two frameworks?
Common, especially for SaaS (SOC 2 plus state privacy plus optionally HIPAA), for dealers (Safeguards plus increasingly state-privacy regimes), and for engineering firms (NIST 800-171 plus ITAR plus state privacy). The capability foundation is the same; we layer the relevant control matrices on top and produce a unified evidence package rather than running parallel programs.
Can we start with one pattern and add the others later?
Yes, and this is the most common adoption path. Many clients start with email-trust hardening and managed SOC, then add the compliance evidence stack when a deal or audit forces the timeline, then add the CUI enclave or PCI scope minimization when a contract or business model change requires it. Each pattern is independently deployable and they layer cleanly.
