Secured, automated, and running on AgentOS

Every website and SaaS platform we build is secured and automated end to end. Every agent runs on XDQ AgentOS, guardrails, human gates and an audit trail included.

FIND · FIX · VERIFY
Secure by default
We test and close the attack surface, web, API, cloud and the AI/agent layer, before you launch, then re-test to verify.
CYBER BRAIN
AI security analysis on watch
An AI security brain reviews new exposure as your product changes, prompt injection, tool abuse, leaked secrets, and flags what moved.
AUTOMATED
Guardrails in the pipeline
Secret scanning, policy checks and guardrails run automatically on every deploy. Human-gated, you approve each change.
FAQ

Questions we get about web & saas product development

What's in an MVP?

Auth, billing, admin, email, the core workflow and a marketing page, working software a customer can pay for, not a prototype.

Can you scale it later?

The MVP is built on the same multi-tenant foundation we run in production, so scaling is adding capacity, not rewriting.

Do you do the marketing site too?

Yes, including SEO structure, pricing pages and lead-magnet calculators.
