SECURITY & DATA

Safe, in plain English.
And in the detail underneath.

LetTrack is a compliance product — which means false claims about security are a liability we won't take. Everything on this page is either live in the platform today, or clearly labelled as roadmap.

B+posture
// self-assessed security posture

Mapped against ISO 27001:2022, NIST CSF 2.0 and OWASP ASVS. Independent third-party certification is on the pre-launch roadmap below.

For tenants

You only ever see your own home. Your data is private, and never sold.

For landlords

A tamper-proof record you can use to prove compliance, later.

For agencies

Client data is isolated per organisation, and audit-ready by default.

For contractors

You see only the job assigned to you — nothing else about the property or tenant.

// shipped today

What's live in the platform now.

Fourteen controls that are switched on for every customer, today. Each shows the plain-English benefit, the technical detail, and how it maps to recognised frameworks.

Who can see what

Every record knows which organisation, role and user is allowed to touch it — and the database enforces it.

01AStrong

Tenant data isolation

You only ever see the world that belongs to you — your home, your properties, or the job you've been assigned. Row-Level Security is enforced at the database layer (organisation_id + membership), so app bugs can't leak cross-tenant data.

ISO A.8.3 / A.5.15NIST PR.AA-05OWASP ASVS V4
02AStrong

Role-based access

Each role gets exactly the access it needs and nothing more. A 9-role hierarchy is enforced in RLS policies; contractors are scoped to assigned jobs only.

ISO A.5.15 / A.5.18NIST PR.AA-05ASVS V4
03AStrong

Isolation is actively tested

The "you can't see other people's data" rule isn't trusted — it's proven. Around 35 automated RLS contract tests attempt cross-tenant access on every release and must pass before code ships.

ISO A.8.29NIST PR.AAASVS V4

Files & sensitive data

Documents are private by default. Right to Rent — the highest-stakes data we hold — gets the strongest lock.

04BSolid

Private document storage

Your files can't be reached by a guessed or shared link. No public storage buckets are used; everything sits in private buckets, with a separate locked store reserved for Right to Rent.

ISO A.8.12 / A.5.23NIST PR.DSASVS V12
05AStrong

Time-limited file access

A document link works only for you, and only briefly. Signed URLs are generated by the server after a permission check; raw storage paths are never exposed to the browser.

ISO A.8.3NIST PR.AA-05ASVS V12
06AStrong

Right to Rent protection

The most sensitive ID and immigration data gets the strongest lock. Stored in a separate bucket with 5-minute links; share code and date of birth are field-level encrypted via pgcrypto, with a key the application never reads, held in a vault.

ISO A.8.24 / A.5.34NIST PR.DS-01ASVS V6

Accountability

If something happens, you can prove what happened — and to whom.

07AStrong

Tamper-proof audit log

An honest, unchangeable record of who did what — useful for proving compliance. Every change is written to an append-only audit_log; database triggers physically block edits and deletes; records carry actor, organisation, action, entity and changed fields.

ISO A.8.15 (+log protection)NIST DE.AE / PR.PSASVS V7
10BSolid

Safe email handling

Test environments can't accidentally email real people; every real email is logged. Sending is dry-run by default; each delivery is recorded with recipient and status.

ISO A.5.14 / A.8.16NIST DE.CM

Encryption, secrets & login

What's on the wire is sealed. What grants power lives where the app can't see it.

08AStrong

Encryption in transit

Everything you send and receive is sealed in transit. HTTPS/TLS is enforced via HSTS (preload) plus hardening headers (CSP, X-Frame-Options DENY, nosniff, Referrer-Policy, Permissions-Policy).

ISO A.8.24 / A.5.14NIST PR.DS-02ASVS V9
09BSolid

Secrets kept out of reach

Powerful keys never touch your browser or our application code. Secrets live in server config only; the most powerful database key is restricted to back-office jobs; the Right to Rent encryption key lives in a vault.

ISO A.8.24 / A.8.4NIST PR.AAASVS V6
12CBaseline

Secure login

Trusted, standard sign-in via Supabase Auth with JWT sessions: email + password (minimum length enforced), magic link, or Google. Two-factor authentication is on the roadmap below.

ISO A.5.17 / A.8.5NIST PR.AA-01 / 02ASVS V2

Where it lives, who handles it

EU-hosted, under strong data-protection law, with a tight third-party footprint.

13BSolid

EU data hosting

Your data sits inside the EU, under strong data-protection law. Hosted on AWS Ireland (EU region) and covered by UK–EU data-protection adequacy. UK residency is on the roadmap if customers require it.

ISO A.5.23 / A.5.34UK GDPR Art.44–46
14BSolid

GDPR foundations

Clear privacy rights, a published privacy policy, defined retention periods, and stated controller/processor positions — LetTrack acts as processor for data uploaded by landlords and agencies. Data-subject-request structures are in place.

ISO A.5.34UK GDPR Art.5 / 12–22
11BSolid

Minimal third parties

Your data isn't sold or scattered across vendors. We use Supabase (data and storage), Resend (email), Stripe (payments, currently off), and Sentry (error alerts). No onward data sharing.

// the small print

  • Ratings are self-assessed. A, B and C labels reflect our own mapping against ISO 27001:2022, NIST CSF 2.0 and OWASP ASVS — they are not externally audited certifications. An independent assessment is on the roadmap.
  • Demo numbers are demo numbers. The illustrative figures shown elsewhere on the marketing site (property counts, percentages, sample timelines) are not live security metrics.
  • Found something we should fix? Security disclosures are welcome at security@lettrack.co.uk.

Questions about how we protect your data?

We'd rather have the conversation than oversell. Reach out and we'll walk you through any of the controls above — or the gaps still on the roadmap.
