Security & trust

Your clients' data, treated like it's ours.

NexusOS is multi-tenant by design. Access control, isolation and encryption are built into the foundation — not bolted on.

Role-based access

Founders, team members and clients each see only what their role allows. Permissions are enforced on every request, not just the UI.

Tenant isolation

Every client organization is partitioned by organization ID. Client portal users can never see another client's projects, files or invoices.

Encryption in transit

All traffic is served over HTTPS/TLS. Data moves between your browser, our servers and storage encrypted end to end.

Managed, backed-up database

Built on a managed Postgres platform with automated backups and point-in-time recovery, so your data is durable by default.

Modern authentication

Sessions use signed JWTs with secure, httpOnly cookies. Enterprise plans add SSO so your team signs in with your identity provider.

Audit logs

Enterprise workspaces get audit logging across sensitive actions, so you always know who did what and when.

Reliable infrastructure

Deployed on a global edge platform with a 99.9% uptime target on paid plans and graceful handling under load.

Least-privilege by design

Internal and client roles are separated at the data layer. The portal re-checks the client's identity on every query.

Why it matters

One agency, many clients, zero leakage.

Agencies hold sensitive material for every client they serve — contracts, financials, creative work, login details. The biggest risk isn't an outside attacker; it's one client accidentally seeing another's data.

NexusOS is built around that reality. Every record is scoped to an organization, and the client portal re-verifies the signed-in client on each request. Internal roles and client roles are separated at the data layer, so a misconfigured screen can never expose what a user isn't entitled to see.

If you have specific compliance requirements — a security questionnaire, a DPA, or SSO with your identity provider — reach out and we'll work through them with you.
