What we build for cybersecurity companies

Six ways we help cybersecurity teams ship, scale, and stay compliant.

01

Cybersecurity Platform Development

Full-cycle development of security platforms: SIEM, GRC, risk management, threat intelligence. From architecture to production SaaS, built for enterprise scale and multi-tenant environments.

02

Embedded AI Security Layer

We add AI to existing cybersecurity platforms without rewriting the core. Conversational interfaces, agentic workflows, and multi-persona UX layered on top of the product your customers already trust.

03

PoC Development

First versions of security products built on architecture that survives growth. Investor-ready prototypes that become enterprise-grade platforms.

04

Compliance-First Engineering

NIST, ISO 27001, NIS2, SOC 2, and GDPR requirements mapped into architecture decisions from day one.

05

Platform Re-Architecture

Modernization of legacy security platforms: performance, scalability, cloud migration, and preparing the codebase for AI capabilities without disrupting production customers.

06

AI Agent Security Architecture

Tenant isolation in the tool layer, MCP integration, prompt injection defense, and agent boundaries designed for multi-tenant security products.

From embedded AI security layers to decade-long enterprise partnerships — here's how we build products that pass security review.

FinTech cloud financing web platform—Siemens Financial Services app for automated loan applications

Cloud-based platform for Siemens Financial Services in Poland

By engineering an omnichannel SaaS application on a secure cloud-based financial platform, we enabled Siemens to deliver 24/7 credit decisions and 1-minute loan processing.

How we build for cybersecurity: the technical decisions that matter

Tenant isolation lives in the tool layer, not the output filter.

For a US cybersecurity platform, we wired every tool call to the authenticated user, organization, and profile at creation. Cross-tenant tool calls aren't filtered. They're not possible.

MCP integration for agent-ready platforms.

Security products without MCP or equivalent integration become invisible to agent-driven enterprise workflows. We build MCP-native, with least-privilege sandboxes and security audits from day one.

Multi-agent architectures over single-model deployments.

Real enterprise value comes from coordinated agent systems with defined boundaries, not one model with one prompt.

Security-by-design from the first sprint.

Code review, dependency scanning, secret detection, SAST/DAST, and penetration testing prep built into CI/CD, not bolted on at audit time.

Compliance and security we build into every engagement

Frequently Asked Questions

How do you add AI to an existing cybersecurity platform?

We build an embedded AI layer on top of your existing product, without rewriting the core. For a US-based cybersecurity platform, we added a conversational interface, agentic workflows querying the live security stack, and multi-persona UX. Onboarding dropped from 45 minutes to under 2 minutes. The existing security architecture stayed unchanged, so no new compliance scope.

What is tenant isolation in AI-powered cyber platforms?

Tenant isolation determines whether an AI agent can access data across customer boundaries. Most implementations filter agent output, which leaves an attack surface: prompt injection or jailbreaks can pull data across tenants. We build isolation into the tool layer: every tool call is wired to the authenticated user, organization, and profile at creation. The model cannot see, pass, or change these identifiers. Cross-tenant calls are architecturally impossible.

How do you comply with NIST, ISO 27001, and NIS2 when building cyber products?

Compliance requirements are mapped into architecture decisions from the first sprint: data flows, access controls, encryption standards, and audit trails designed against the frameworks that apply to you. Our operations are ISO 27001 certified, and we've delivered NIST and CIS compliant platforms for US cybersecurity clients.

How do you handle sensitive customer data in cyber SaaS development?

Dedicated cloud clusters in your specified region, encryption at rest and in transit, read-only integrations by default, and full audit trails. We never train AI models on your data. For one cybersecurity client, we run a dedicated GCP cluster exclusively for their sensitive calculations.

What's the difference between building a cybersecurity SaaS and a regular SaaS?

Three things. First, the buyer: security products pass enterprise security reviews before anyone sees the demo, so architecture decisions carry sales weight. Second, the data: threat intelligence and risk data demand stricter isolation, encryption, and auditability than typical B2B data. Third, compliance: NIST, ISO 27001, and SOC 2 aren't optional add-ons but core product requirements from day one.

Should we build our cyber platform in-house or work with a specialized dev partner?

In-house makes sense when platform engineering is your core differentiator and you can hire senior security-minded engineers fast. A specialized partner makes sense when speed matters: an experienced team ships your MVP or AI layer in months, not quarters, and transfers knowledge as you scale your own team. Many of our engagements are hybrid: our engineers work inside the client's sprint cycle, then hand over.

We build what comes next.
