Smart Solutions

Security engineered into the system, not bolted on

We design AI-augmented systems where the destructive actions need human approval, audit trails are immutable, and secrets never touch disk in plaintext. LGPD / GDPR by design, zero-trust by default.

What we deliver

Trust ladder for AI agents

Per-integration trust levels (read → suggest → auto) with explicit thresholds. The agent reads anything, suggests with confidence threshold, auto-executes only the safe playbooks. Destructive actions always need human approval.

Immutable audit trails

Database triggers block UPDATE / DELETE on the audit table — only single-shot reverts allowed. Every AI decision, every webhook, every credential rotation traced and queryable forever.

Server hardening

fail2ban + UFW + TLS hardening + SSH key-only access + automatic backups (S3 + provider snapshots) + restricted admin panels. The boring infrastructure done right.

LGPD / GDPR-aware design

Data minimization, retention windows, right-to-erasure flows, consent tracking, controller documentation. Privacy isn't a checkbox — it's the data model.

Secret management

1Password CLI with service accounts for CI/CD — secrets injected at runtime, never written to disk in plaintext. Per-environment scoping. Rotation playbooks documented and tested.

Zero-trust access

Cloudflare Access (Google / GitHub / SAML SSO) for internal apps. OAuth flows for third-party integrations. Webhooks authenticated via HMAC SHA-256. No public internal services.

AI safety guardrails

Prompt injection prevention, jailbreak detection, content moderation on RAG inputs, output filtering for PII, audit of LLM calls. AI security as a first-class concern.

  • sops + age

Network & Perimeter

  • Cloudflare WAF
  • Cloudflare Bot Management
  • fail2ban
  • UFW / iptables
  • Let's Encrypt TLS
  • DNSSEC

Audit & Compliance

  • LGPD (Brazil)
  • GDPR (EU)
  • Immutable audit trails
  • DB-level triggers
  • Single-shot revert

Backup & DR

  • S3 + lifecycle policies
  • Provider snapshots (AWS, DO, Hetzner)
  • Restore drills
  • RTO / RPO documented

AI Safety

  • Prompt injection prevention

Cases

Trust ladder + audit trails — own command center

Production system where every AI suggestion is logged, every auto-action revertible single-shot, every integration scoped by trust level. Reference architecture under NDA.

Server hardening + backup automation — retail

WordOps stack hardened with fail2ban + UFW, automated backups to S3 + provider snapshots, restricted admin panels behind WAF. Zero successful intrusion attempts since migration.

Credential rotation playbook — multi-client

180-day rotation cycle for all API tokens, SSH keys and database passwords across portfolio. Documented in 1Password with TTL and validation scripts.

Security shouldn't slow you down — design it in

We assess your current posture, identify the gaps that matter and propose hardening that doesn't break delivery.
