Engineering for cybersecurity & AI security
Disarmista is a software engineering boutique for cybersecurity innovation. We help security companies — from first prototype to global scale — build, ship, and harden complex products, from endpoint drivers to AI agents.
Security products are technically demanding — and AI is raising the stakes. Agents act, tools execute, models decide, and every seam is a new attack surface. We embed with your team and deliver production-grade software that closes them.
Trusted by leading cybersecurity and technology companies — from early-stage startups to global security vendors.
Three practices. One discipline: security as an engineering property, not an afterthought.
Beyond assessment — we design and build the security layer of AI-powered systems. Agent sandboxing and permission models, prompt-injection defense in depth, tool-call mediation, data isolation, and secure MCP and model integrations.
Products and prototypes built with AI-augmented engineering workflows — agent systems, MCP servers, AI-native tooling and security automation. Delivered by engineers who understand the failure modes of the systems they build with.
Our founding practice: hands-on engineering across the full product lifecycle — architecture, prototyping, implementation, performance optimization, security hardening, integrations, and long-term support. From kernel drivers to cloud-native platforms.
Systems our team has built and improved for security companies worldwide.
Antivirus, endpoint agents, and detection & response systems — from kernel drivers to detection pipelines.
Firewalls and network security products engineered for performance at line rate.
Reverse-engineering tooling and data-intensive analysis systems for threat research at scale.
Protocols and primitives, zero-knowledge proofs, key management, and blockchain & Web3 security infrastructure.
AI security products, agent sandboxing engineering, and security automation tools — the newest generation of the defensive stack.
Desktop agents, drivers, backend services, and cloud-native platforms that hold it all together.
Cybersecurity startups seeking experienced technical execution, and established technology companies investing in innovation. We have helped global security vendors build the systems they are known for, and partnered with startups from first prototype through acquisition — staying on to help them grow inside their new home. That continuity is one of our core skills.
Senior engineers who quickly absorb complex domains, operate with autonomy, and deliver reliable software in security-sensitive environments.
