Privacy & security architecture

Privacy by design.
Built in, not bolted on.

Privacy isn't a feature you add in week 22. It's an architectural decision made on day one. We engineer data minimisation, encryption, access control, and auditability into the foundation — so your platform is defensible the moment it goes live.

The trap

The compliance debt
trap.

Most SaaS products are built to ship features fast. Privacy and security get postponed to "after launch" — at which point retrofitting them is two to ten times more expensive than building them in. By the time the first regulator letter or first procurement questionnaire arrives, the architecture has already locked in the wrong defaults.

Regulatory exposure UK GDPR fines up to 4% of global turnover. ICO investigations. Data subject access requests you can't fulfil because nobody mapped where personal data lives.
Procurement blockers Enterprise customers send 200-question security questionnaires. If you can't answer them with evidence — encryption keys, access logs, retention policies — the deal dies in legal review.
Breach blast radius If you store everything forever in plaintext, a single compromised credential exposes the whole dataset. Minimisation and encryption are damage control before damage happens.
How we engineer it

Privacy as
architecture.

These aren't features in a sprint backlog. They're constraints we honour from the first commit.

Data minimisation

We collect and store only what the product genuinely needs. No "let's grab everything in case it's useful later." Every field we keep has a documented purpose, lawful basis, and retention period.

Encryption at rest & in transit

TLS 1.3 everywhere. Disk-level encryption on every database. Application-level encryption on sensitive columns (PII, payment data, health data). Keys managed via KMS — never embedded in code.

Role-based access control

Every endpoint guarded by RBAC. Permissions inherited from roles, not granted ad hoc to users. Sensitive actions require step-up auth. Service accounts are scoped to the minimum API surface they need.

Immutable audit trail

Every read and write of sensitive data logged with user, timestamp, IP, and outcome. Logs append-only, replicated, and queryable for DSARs, breach investigations, and ISO/SOC audits.

Retention & right-to-erasure

Retention policies enforced by the database, not by intent. "Delete my account" is a one-click operation that propagates to every system. Backups age out on schedule. Tombstones, not orphans.

Tenant isolation

For multi-tenant SaaS: row-level security in the database, not just in the application layer. A bug in your code can't cross-leak Customer A's data to Customer B because the database itself refuses.

The architectural difference

Bolt-on vs
built-in.

The difference between a platform that has privacy controls and one that is privacy-aware shows up everywhere — in incident response time, in DSAR fulfilment cost, in procurement-questionnaire pass rates, in how cleanly you can answer the regulator's first question.

It's not a marketing exercise. It's the same code, designed differently.

Bolted on later

  • "Where does email live?" → 3 days to find out
  • DSAR deletion misses 4 systems
  • Audit log gaps for first 18 months of operation
  • Encryption keys in env vars, on every server
  • Tenant isolation at app layer only

Built in from day one

  • Data map is the schema; answer is one query
  • Deletion is one transaction, propagated everywhere
  • Append-only audit log from first commit
  • Keys in KMS; never visible to application code
  • Row-level security at the database
