The Agentic Security Problem
AI is moving from generating text to orchestrating enterprise systems. As autonomy increases, perimeter defenses become blind to reasoning-level exploits.
From Generating Answers to Taking Actions
Yesterday, AI generated passive text. Today, autonomous agents execute shell scripts, invoke internal APIs, modify databases, and dispatch financial transactions.
Unchecked Tool & Capability Abuse
When an agent is given tool execution rights (Python REPL, SQL execution, file access), a single indirect prompt injection can hijack the tool call with full machine authority.
Cross-Tenant Memory & RAG Bleed
Autonomous agents maintain persistent memory and semantic vector caches. Without cryptographic tenant boundaries, private context easily bleeds across sessions.
Delegated Identity & Superuser Sprawl
Agents frequently run with high-privilege service credentials. If an agent is coerced, the attacker inherits those credentials without triggering standard perimeter alerts.
DEFYRA Validates What Actually Happens When AI Acts
We do not just evaluate chatbot toxicity. We execute scoped, authorized security tests to prove whether your agents can be tricked into exceeding their intended authority.
The Full-Chain AI Attack Path
AI security cannot be solved by simple prompt firewalls. DEFYRA validates the complete attack chain from untrusted input down to business impact.
Untrusted Input
Adversarial payloads, document uploads, web scrapers, user chats
- •Direct prompt injection overrides
- •Invisible zero-font payload injection in PDFs
- •Multimodal image-embedded jailbreaks
Systematic semantic perturbation & multi-modal injection sweeps
Raw input stream, tokenized representations, boundary safety logs
Cybersecurity Services Engineered for AI
DEFYRA provides specialized security validation and red teaming designed specifically for the unique vulnerabilities of modern AI systems.
AI Security Validation
Rigorous, evidence-backed security validation to verify whether deployed AI models and systems adhere to explicit safety and isolation constraints.
Adversarial AI Red Teaming
Expert-led and automated adversarial simulation probing for prompt overrides, jailbreaks, logic evasion, and multi-turn manipulation.
Agent Security Assessment
Targeted validation of autonomous agent decision loops, preventing excessive agency, runaway delegation, and unconstrained action execution.
RAG & Memory Security Testing
Ensuring vector databases, semantic caches, and long-term memory stores are immune to context poisoning, ACL bypass, and tenant bleed.
Tool & API Security Validation
Testing the boundary between LLM reasoning and code execution. Probing function-calling endpoints, REPLs, and backend microservices.
Agent Identity & Authorization
Validating that agent service accounts, OAuth tokens, and delegated credentials enforce least privilege and resist identity forgery.
Model Context Protocol (MCP) Testing
Deep security evaluation of MCP servers, client handshakes, tool manifests, resource spoofing, and capability declarations.
Continuous AI Security Validation
Automated CI/CD security gatekeeper testing new agent prompts, tools, and model weights against regression test suites prior to deployment.
The DEFYRA Validation Workflow
Every security engagement follows an auditable 12-stage validation lifecycle to ensure authorized execution, zero collateral damage, and indisputable proof.

Indirect Prompt Injection via Web Retrieval
Verify if untrusted third-party web content can hijack agent execution during RAG retrieval
Agent parses web text as passive data without executing embedded instructions
Autonomous Unconstrained File System Access
Determine if an agent can execute arbitrary file reads/writes outside authorized directory
Agent tool wrapper strictly enforces chroot/sandbox boundaries and logs traversal attempts

Memory retrieval is strictly scoped by authenticated tenant and session ID
Tool Permission Boundary Bypass
Attempt to invoke administrative tools using standard user privileges via prompt manipulation
Tool execution engine validates caller RBAC server-side before execution
MCP Protocol Server Privilege Escalation
Test whether Model Context Protocol (MCP) server capabilities can be abused beyond declared manifest
Client runtime strictly limits MCP server access to declared capabilities and paths
Server-Side Request Forgery (SSRF) via Web Tools
Evaluate if web retrieval tools can be coerced into scanning internal cloud metadata endpoints
HTTP client rejects requests to loopback, private RFC 1918 IPs, and cloud metadata services
Direct System Prompt Override

Evidence-Driven Security. Not Subjective Claims.
DEFYRA stands on the principle of PROVE. PROTECT. TRUST. We replace hand-waving assertions with tamper-evident technical artifacts that engineering and executive leadership can rely on.
Cryptographic SHA-256 Proof
All captured payloads, network traces, tool execution parameters, and model outputs are hashed upon collection and cryptographically sealed.
DEFYRA RiskModel v0.1
Transparent multi-factor scoring factoring in blast radius, agent autonomy, data sensitivity, and privilege level. Zero fake 100% security scores.
Automated Retest Lifecycle
Once remediations are deployed, rerun exact regression payloads to verify and prove vulnerability resolution before production signing.
Point-in-Time Assurance Reports
Executive and technical reports complete with scope boundaries, tested methodology, reproduction steps, and verifiable evidence references.
