Prompt injection. Data exfiltration. Uncontrolled tool access. Multi-agent systems are powerful, and dangerously under-secured.
Paratele designs, builds, and hardens multi-agent architectures so the things that could break trust never get the chance.
Grounded In
Every platform will sell you an agent builder. Nobody's asking the hard questions: What happens when Agent A hallucinates instructions to Agent B? Who controls tool access? Where's your blast radius? That's where we come in.
Teams spin up agents without architecture guardrails. Each one becomes a potential attack surface with unchecked tool access and no observability.
We've audited systems where a single "helper" agent had write access to production databases, S3 buckets, and three external APIs — and nobody knew it existed until the security review.
Most agent deployments bolt on security later, if at all. Prompt injection, data exfiltration, and privilege escalation risks hide in plain sight.
In every multi-agent system we've threat-modeled, we find at least one path where a compromised agent can escalate to data it was never meant to touch. Every single one.
Multi-agent systems need more than a framework. They need deliberate architecture: communication patterns, failure modes, and trust boundaries designed from day one.
We've seen 5-agent systems with over 40 implicit trust relationships. Most teams can't draw their own blast radius on a whiteboard — that's the gap we close.
Our methodology is grounded in established security frameworks — MAESTRO, OWASP LLM Top 10, MITRE ATLAS, NIST AI RMF, and STRIDE — adapted for the unique challenges of multi-agent AI systems.
Explore our framework →From architecture design to ongoing advisory, we meet you where you are in your agent journey. Every engagement delivers compliance-ready architectures built for regulated environments.
You're building a system where 20 agents coordinate across three services. We'll map every communication path, every tool permission, every failure mode, then threat model the whole thing before you write a line of code. You get an architecture with STRIDE analysis at every trust boundary, not a slide deck with arrows and optimism.
Outcome: You walk into security review with a threat model that answers their questions before they ask them. Self-hosted and sovereign deployment options available.
Your agents are in production. Do you know what happens if someone prompt-injects your intake agent? Do you know which agents can reach your database directly? We'll map every exfiltration path, every privilege escalation vector, every tool permission that's wider than it should be. Then we give you a fix list in priority order.
Outcome: A prioritized remediation roadmap with specific architectural fixes, not a 60-page findings report that sits in a drawer. You'll know exactly what to fix Monday morning.
Agent A delegates to Agent B, which calls a tool, which triggers Agent C, which writes to a database that Agent D reads from. Now Agent A hallucinates. What's your blast radius? We design the orchestration layer so you can answer that question: routing, state management, trust boundaries, and human-in-the-loop controls that actually contain failures instead of cascading them.
Outcome: An orchestration architecture where every failure mode is mapped and contained. Deployable on cloud or your own infrastructure. Your data classification drives the decision, not your vendor's preference.
New agent framework dropped. Your team wants to adopt it. Is it secure? Your orchestration layer grew three new agents last month. Did the trust boundaries keep up? You need someone who's in this space daily, not a consultant who reads the changelog once a quarter. Architecture reviews, security posture checks, vendor evaluation. On your schedule, at practitioner depth.
Outcome: Your team stays ahead of emerging threats and architectural drift without hiring a full-time AI security architect. We're the person you Slack when something doesn't look right.
Every engagement follows a deliberate process. No shortcuts, no hand-waving. Each phase builds on the last to deliver architecture that's secure by design, not by accident.
Map your agent environment, data flows, infrastructure constraints, and security requirements. We learn your system before we touch your architecture.
STRIDE-based threat modeling across every agent interaction, data flow, and trust boundary. We identify what can go wrong before it does.
Build the architecture with security controls embedded, not bolted on. Communication patterns, access policies, failure modes, all documented.
Validate the architecture against MAESTRO, OWASP LLM Top 10, and MITRE ATLAS. Every design decision is tested against known attack patterns.
Deliver production-ready documentation, architecture diagrams, and threat models. Your team is equipped to build, operate, and maintain the system.
Real systems. Real security challenges. Anonymized to protect our clients, but detailed enough to show how we think.
A multi-agent system spanning cloud and local compute, designed for security-first multi-domain operations.
The organization needed specialized agent teams across multiple domains: security operations, research, infrastructure management, with strict data isolation between teams and flexible deployment across cloud and local compute. Agents in different domains needed to collaborate without violating trust boundaries.
Graph-based agent routing with relationships and trust boundaries stored in a queryable graph database. Hybrid cloud and local compute deployment driven by data classification. Sensitive operations run on local infrastructure, scale workloads push to cloud. Multi-lens analysis patterns where multiple agents analyze the same problem from different perspectives, with aggregated and validated outputs.
End-to-end data controls with strict separation between internal and external audience handling. Open-ended agent workflows (exploratory research) and directed agent workflows (constrained operations) maintain different security postures. The exploratory agents can't reach production data, and the constrained agents can't deviate from approved patterns.
Production system spanning multiple interconnected systems with defined trust boundaries and full audit capability on every inter-agent communication.
Secure data processing across agent workflows with classification-based routing and strict access controls.
Agents needed to collect, process, and analyze data from multiple sources while maintaining strict security controls based on data sensitivity. Different data classifications required different handling, and the agents processing the data needed to be isolated from each other to contain potential breaches.
Classification-aware routing where agents only access data at their clearance level. Microservices-based pipeline deployable to AWS, GCP, Azure, or local compute. Collection and scraping agents fully isolated from analysis agents. Blast radius containment ensures a compromised collection agent can't reach analytical outputs or cross-classification data.
Data never moves between classification levels without explicit policy enforcement. Full audit trail on every agent data access event. Encryption in transit and at rest across all pipeline stages. Policy-as-code for data movement rules. No implicit trust, no inherited permissions.
Fully auditable data pipeline with zero cross-classification leaks. Every data access logged and traceable. Deployable across cloud providers or on-premises with identical security guarantees regardless of infrastructure.

Try the Threat Mapper →Paratele exists because the people building multi-agent AI systems and the people who understand how to secure them are rarely the same people. We're both.
Multi-agent systems in production. Orchestrated, secured, and operating in the real world. Not demos. Not proofs-of-concept. Real systems handling real workflows across hybrid cloud and local infrastructure.
Two decades of cybersecurity and cloud architecture taught us how systems break. Building production multi-agent systems taught us where AI agents break specifically. That intersection, deep security expertise meets hands-on agent engineering, is what makes Paratele different from consultancies reading whitepapers and platforms selling drag-and-drop.
Every architecture decision runs through a STRIDE threat model. Security isn't a layer. It's the foundation everything else is built on.
We build with the tools. We don't sell them. Our recommendations come from production experience, not partnership agreements.
Frameworks inform our work. They don't replace it. You need an architecture that ships, scales, and doesn't break trust. Not another compliance checklist.
Every architecture we design can run on your infrastructure. Cloud, on-prem, hybrid. Your data stays where you decide it belongs.
