A secure new firm technology setup begins with identity, records and recovery—not a shopping list of apps. Define the services the firm must deliver, the data it will hold and who is responsible. Then choose the smallest supportable stack that meets legal, professional and client requirements.
Design the architecture before purchasing
Map users, locations, client interactions, regulated data, critical workflows and expected growth. Assign a system of record for contacts, documents, accounting, work, contracts and credentials. Avoid adopting overlapping tools without a migration and exit plan.
| Layer | Launch requirement | Owner |
|---|---|---|
| Domain and identity | Registrar protection, MFA, admin separation | Named administrator |
| Devices | Inventory, encryption, updates, remote lock | IT owner |
| Records | Approved storage, access and retention | Records owner |
| Finance | Banking, ledger, billing and approvals | Finance owner |
| Continuity | Backups, recovery contacts and tests | Business owner |
Secure identity and email first
Protect the domain registrar, DNS, email administrators and recovery accounts with phishing-resistant MFA where possible. Use named accounts and separate privileged administration. Configure SPF, DKIM and DMARC, then create an independent verification process for payment changes. See the detailed email security checklist.
Configure devices and access
Use supported operating systems, disk encryption, managed updates, screen locks, endpoint protection and secure disposal. Grant access by role and record approvals. Define onboarding, role change and same-day offboarding. Remote work needs approved networks or secure access, private calls and a process for loss or theft.
Set records and finance controls
Choose where final documents live, how files are named, who can share them and how long they are retained. Establish accounting periods, chart of accounts, expense evidence, billing, collections, bank reconciliation and separation of payment duties. Do not let the CRM, inbox and ledger each become a different customer master.
Test continuity before launch
- Back up critical configurations and data using separate protection.
- Restore a representative file and system record.
- Simulate a lost administrator device.
- Export essential client and financial data.
- Record vendor support, insurer, bank and legal contacts offline.
- Run a tabletop incident and update the plan.
Thirty-day launch sequence
Before client data: approve architecture, identity and policies. Before first engagement: test portal, contract, billing, records and backup. During the first month: review access, reconcile financial systems, inspect security alerts and collect workflow problems. Delay optional automation until the underlying process is stable.
Frequently asked questions
Which software should a new firm buy first?
Identity/email, secure records, accounting/billing and backup usually form the core, but professional duties and service model determine the exact stack.
Can one person hold every administrator role?
A very small firm may have limited staffing, but it can still use separate admin accounts, dual approval for high-risk changes, logs and an external recovery contact.
When should security be reviewed?
Before client data is accepted, after material system or staffing changes, and on a recurring risk-based schedule.
