Agentic system assurance
Threat modeling and adversarial review for agents, MCP and A2A systems, tool use, memory, identity and human-approval boundaries.
Independent security assurance for autonomous systems
Autonomy without assurance is just attack surface.
Delx Security helps teams ship AI agents, software products and cloud systems with bounded authority, verifiable controls and a credible path through failure.
What we secure
Security that follows the system all the way to production.
The work starts with mission and architecture, follows the highest-risk paths into implementation, and ends only when remediation is verified. An AI agent security assessment is useful only when the owner can see the authority, evidence and residual limits. No generic checklist theatre. No unbounded testing.
Product security review
Evidence-led review of applications, APIs and cloud architecture against explicit controls, attack paths and production behavior.
Secure delivery systems
Practical security engineering for software supply chains, release gates, secrets, access control and observable operations.
Incident readiness
Runbooks, tabletop exercises and containment plans built around the systems, dependencies and decisions that actually matter.

Operating doctrine
Assume complexity. Remove ambiguity.
Bound authority
Every autonomous action needs an identity, an allowed scope and a revocation path.
Verify behavior
Configuration is intent. Runtime evidence is what proves the control is alive.
Design for failure
Detection, containment and recovery are product capabilities, not emergency paperwork.
Leave evidence
Every finding connects risk, proof, remediation and a reproducible verification step.
Standards, translated into action
Grounded in public frameworks. Tailored to the real system.

Framework alignment is a method, not a certification claim. Scope, evidence and limitations are stated in every engagement.
A bounded engagement
From uncertainty to a decision-grade security record.
- 01Frame
Define the system, business impact, authority and written rules of engagement.
- 02Model
Map assets, trust boundaries, agent actions, abuse cases and credible failure paths.
- 03Verify
Test controls with proportionate, authorized techniques and preserve reproducible evidence.
- 04Improve
Prioritize fixes by exploitability and impact, then verify the remediated behavior.
Direct answers
Before a review begins.
Clear boundaries are part of the assurance work. These answers describe what Delx Security does and does not claim.
What does Delx Security do?
Delx Security provides defensive assurance for AI agents, applications, APIs and cloud-native systems: threat modeling, product security review, secure delivery systems and incident readiness.
What is an AI agent security assessment?
An AI agent security assessment is a bounded review of identity, delegated authority, tools, context, memory, egress, side effects, evidence and recovery. It connects credible abuse paths to remediation and a repeatable verification step; it is not a certification or guarantee.
Can Delx Security review an MCP server?
Yes, when the owner gives written authorization. The review can cover the server card, tool and resource schemas, authentication, input validation, side effects, egress, secrets, revocation and runtime evidence. Unbounded scanning and third-party testing are out of scope by default.
Does Delx Security perform testing without authorization?
No. Active testing begins only after an auditable Rules of Engagement defines the assets, techniques, time window, contacts and stop conditions. Research environments use synthetic data by default.
Does Delx Security issue security certifications?
No. Delx Security can map evidence to public frameworks such as NIST CSF, NIST AI RMF, OWASP and MITRE ATLAS, but it does not claim third-party certification unless formally qualified.
How does a Delx Security review work?
A bounded engagement frames the system and authority, models assets and abuse paths, verifies controls with proportionate authorized techniques, and verifies remediation with reproducible evidence.
How does Delx Security relate to Delx?
Delx Security is Delx's defensive assurance arm. It owns authorized security reviews, threat models and defensive research; the Delx platform map shows Security alongside separate Protocol, Wellness, Commerce and Astral properties.
