Fusion Security is a small studio that does both sides of the job. We audit and harden your systems, then design the mobile apps, SaaS products and AI tools your business needs next, with security built in from the first line of code.
Most teams hire one firm to build and another to find out what went wrong. We do both, so the people writing your code are the people who know how it gets attacked.
Audits, hardening and a remediation plan your team can actually follow.
Agents, automations and LLM features wired into the tools you already use.
iOS and Android apps, taken from first sketch all the way to the stores.
Platforms and sites built on infrastructure we know how to defend.
We map your goals, your users and what you need to protect before anything gets built.
We work out how the product could be attacked and design the defenses into the architecture.
We ship in short iterations you can test, with code review and security checks at each step.
We deploy, monitor and maintain, and keep dependencies and cryptography current.
We build, host and secure our own software in production. What we learn there goes into every client project.
Quantum computers will break the public‑key cryptography most systems rely on today. PQC Status inventories the cryptography in your infrastructure, flags what is quantum‑vulnerable, and tracks your migration to the new NIST post‑quantum standards.

Visit fusion-ai.cloudFusion Security is operated by FUSSEC Services LLC. The company grew out of more than a decade of hands‑on infrastructure and security work: network and security engineering at a managed hosting provider, then independent consulting since 2015 for banks, financial firms, media groups and an electronic‑signature trust provider.
That work covered security audits, firewalling, directory and messaging infrastructure, and large migrations, such as merging the Active Directory of two banking entities with 2,500 users.
Since 2024 we have also designed AI products and automations and trained more than 150 professionals to use AI in their daily work. Today we bring the two together: software that is useful, and secure from the start.
