LLB GROUP

We build your platform, run it and keep it secure.

LLB Group develops web platforms, operates the infrastructure they run on and manages their security. One team answers for the code, the servers and the protection around them.

Three services, one team accountable.

We build the software, host it and protect it. When something needs attention, you talk to the people who wrote the code and run the servers.

Platform development

We design and build the software your business runs on: client portals, CRMs, dashboards, internal tools and APIs.

  • Web apps in Next.js and React
  • APIs and back ends in FastAPI and Python
  • PostgreSQL data models and migrations
  • Integrations with payment providers, CRMs and trading servers
U02

Infrastructure and operations

We host and run what we build, on servers we size, monitor and maintain for the workload they carry.

  • Dedicated and cloud servers on Hetzner, AWS and Vultr
  • Linux and Windows Server administration
  • Deployments, monitoring and uptime alerts
  • Backups with scheduled restore tests

Security of the platforms we build

Security is part of the work from the first commit. We harden every layer, watch it in production and fix issues as soon as they appear.

  • Cloudflare WAF rules, rate limiting and bot protection
  • Origins with no exposed ports through Cloudflare Tunnel
  • Code review and dependency vulnerability checks
  • Incident response and fixes at the root cause

Security at every stage.

The same process on every platform, from the first design to the day something goes wrong.

  1. Stage 1

    Design

    We map what needs protecting: data, user accounts, payments and admin access.

  2. Stage 2

    Build

    Code review, dependency checks and secrets kept out of the codebase.

  3. Stage 3

    Deploy

    Hardened servers, least-privilege access and no inbound ports left open.

  4. Stage 4

    Operate

    Edge filtering, monitoring, access logs and backups we test by restoring them.

  5. Stage 5

    Respond

    We contain the issue, fix the cause and add a rule so it does not happen again.

Our security scope

Our security work covers the platforms we build and the systems clients contract us to maintain. We never test third-party systems without written authorization from their owner.

What you run todayThe platform, the stack and where it is hosted.
What you needA new build, a migration, ongoing operations or a security review of a system you own.
