Security & Trust

How we protect the sensitive estate, financial, and personal information that executors and their attorneys entrust to us.

1. Encryption & Data Protection

Encryption in transit (TLS/HTTPS)

Every connection to EstateProFiler — web pages, API calls, and file transfers — is encrypted with TLS 1.2 or higher. TLS certificates are automatically managed and renewed; the application is not reachable over unencrypted HTTP.

Password protection

Account passwords are hashed with bcrypt, an adaptive, salted hashing algorithm designed to resist brute-force attacks. Plaintext passwords are never stored, logged, or transmitted to third parties, and cannot be recovered — only reset.

Secrets management

API keys, signing secrets, and database credentials are stored in server-side environment configuration — never in client-side code, never in the browser, and never committed to source control.

2. Authentication & Session Security

HttpOnly, secure session cookies

Sessions are carried in httpOnly cookies that JavaScript cannot read, which neutralizes the most common session-theft vector (XSS token exfiltration). Cookies are flagged Secure in production so they are only ever sent over HTTPS.

Short-lived, rotating tokens

Access tokens expire after 15 minutes and are silently rotated using a 7-day refresh token. When a password is reset, all existing sessions are invalidated server-side, immediately signing out any device that held the old credentials.

Google sign-in (OAuth 2.0)

Users may authenticate with their Google account via OAuth 2.0. In that flow no password exists on EstateProFiler at all — identity is verified by Google and only the resulting verified email and name are stored.

Two-factor authentication (2FA)

Password-based accounts can enable TOTP two-factor authentication using any standard authenticator app (Google Authenticator, Authy, 1Password). When enabled, a valid time-based code is required after the password before any session is issued, and one-time backup recovery codes (stored only as bcrypt hashes) are provided for account recovery. Recommended for executors administering high-value estates.

Brute-force protection

Authentication endpoints are rate-limited. Repeated failed sign-in attempts are throttled both per account and per source address, and the same protection is applied to registration and to password-reset requests — sharply limiting credential-stuffing and password-guessing attacks.

Password reset controls

Password resets use single-use, expiring tokens delivered to the account email. Reset links cannot be replayed once used, and completing a reset invalidates every existing session across all devices.

3. Access Control & Data Isolation

Per-estate data scoping

Every API request is verified against the requesting user’s identity. A user can only read or modify an estate they own or one they have been explicitly invited to. There is no cross-tenant visibility of any kind.

Role-based collaboration

Estates support three roles — Owner, Co-Executor, and Viewer — granted only through email invitations that the recipient must accept. Only the estate owner can change collaborator roles or revoke access, and invitations sent to one email address cannot be accepted by another.

Client share links (read-only)

Attorneys and heirs can be given read-only share links that are time-limited (1–365 days, 90 by default), revocable at any time, optionally password-protected (with a minimum length and the password itself bcrypt-hashed, submitted via a request header rather than the URL, and rate-limited against guessing), and restricted to only the sections the owner chooses to expose. Every access is counted and links return a permanent “expired” response once revoked.

4. Financial Data Handling

Bank credentials never touch our servers

Bank account linking is performed through Stripe Financial Connections. The account holder enters their banking credentials directly into Stripe’s secure interface — those credentials are never seen, transmitted through, or stored by EstateProFiler. Stripe is PCI-DSS Level 1 certified (the highest level) and SOC 1 / SOC 2 audited.

Minimal financial data retention

From a linked bank account we store only the institution name, account nickname, last four digits, balance, and the individual transactions the executor explicitly reviews and approves for import. Linked accounts can be disconnected at any time, which also severs the connection at Stripe. A checkout or payment session can only ever be applied to the account that initiated it.

Payments

Subscription payments are processed entirely by Stripe. Card numbers are entered on Stripe-hosted payment pages and are never stored on, or transmitted through, EstateProFiler servers.

5. Administrative Safeguards & Auditability

Restricted administrative access

Administrative functions are limited to a small, explicitly allowlisted set of accounts. Requests to administrative endpoints from any other account return “not found” rather than “forbidden” — a defense-in-depth measure that avoids even revealing that the endpoints exist.

Administrative audit trail

Every administrative action (account changes, refunds, data corrections) is recorded in a dedicated audit log with the acting administrator, the action taken, and a timestamp.

Per-estate activity log

Each estate maintains its own activity timeline recording who created, modified, imported, or deleted each record and when — useful both for probate accountability and for security review.

6. Infrastructure & Application Protections

Managed cloud infrastructure

EstateProFiler runs on managed, containerized cloud infrastructure (Kubernetes) with the database isolated from public access. Application traffic reaches the platform only through the TLS-terminating ingress layer.

Strict cross-origin policy

The API only accepts browser requests from our own known application domains (an allowlist), rather than any origin. This closes off cross-site request abuse from untrusted websites.

Safe file handling

Uploaded documents and attachments are validated by extension, stored with a server-determined content type (never the value a client claims), and served with download-forcing and no-sniff headers so an uploaded file can never be executed as a script in the browser. Downloads are private and access-controlled to the estate.

Email practices

Transactional and follow-up emails are delivered through Resend (SOC 2 Type II). All marketing sequences honor one-click unsubscribe (RFC 8058) and CAN-SPAM requirements, and unsubscribe requests take effect immediately.

7. Your Data, Your Control

Export anytime

The complete cash ledger exports to CSV and all reports export to PDF at any time — the estate’s records are never locked inside the platform.

Deletion & disconnection

Linked bank accounts can be disconnected instantly by the account holder. Full account and estate data deletion is available on request and removes the estate and all of its child records.

Purpose limitation

Estate data is used solely to provide the service to the account holder and their invited collaborators. It is not sold or shared with advertisers.

Infrastructure partner certifications

Our most sensitive workloads — payments, bank credentials, identity, and email — run on independently audited infrastructure.

Stripe

Payments & bank connections

PCI-DSS Level 1SOC 1SOC 2

Handles all card payments and all bank credential entry. The highest level of payment-industry certification.

Google

Optional sign-in (OAuth 2.0)

ISO 27001SOC 2 / SOC 3

Users who choose Google sign-in are authenticated on Google’s certified identity infrastructure — no password is ever stored with us.

Resend

Email delivery

SOC 2 Type II

Delivers transactional and lifecycle email on audited infrastructure.

A note on our own certifications

EstateProFiler itself does not yet hold an independent SOC 2 or ISO 27001 certification — those attest to company-wide audit programs and we believe in being straightforward about that. What we can demonstrate today is the concrete set of technical controls documented above, plus the certifications of the audited infrastructure partners that handle our most sensitive workloads (payments, bank credentials, identity, and email).
