Agentic AI Security
Secure the AI agents you've given access to
Your agents read code, call APIs, query databases and run commands. We find out what they can reach, test how they fail, and build the controls that keep them in bounds. We run agents on production systems ourselves, under the same controls.
The questions we answer
Six things you should know about every agent you run
- 01 Which agents, models and MCP servers are running, and who owns them?
- 02 What can each one reach, and with whose credentials?
- 03 What can it change without a person approving it?
- 04 Which inputs can steer it: documents, web pages, tickets, emails?
- 05 Is every action logged and traceable to a person?
- 06 How do you stop one that misbehaves?
Engagements
Assess, attack, then engineer
Inventory and threat model
We map your agents, models, MCP servers and tools, what each can access, and where untrusted input reaches them.
Agent and MCP assessment
We review tool permissions, credential handling, approval flows, logging and isolation against how the agent is actually used.
AI red teaming
We attack your LLM features and agents: prompt injection, data leakage, tool misuse and excessive agency, with a proof of concept for every finding.
Guardrails engineering
We implement least-privilege tool access, approval gates for risky actions, credential isolation, audit trails and prompt-injection guards.
Proof
We build agents that act on real systems, and the controls around them
OpsMaxx
AI agents operate real server fleets through 28 MCP tools, each set to allow, ask or deny. Agents never receive passwords, keys, hostnames or a root shell, output is redacted, and every action is audited.
Learn more →DSO
AI triages findings and writes fixes, and a person approves every verdict and every fix. The AI never receives the repository credential, and fixes over 400 lines are refused.
Learn more →X-Security
A prompt-injection guard for LLM endpoints, enforced at the API gateway and compiled deterministically, with no model in the enforcement path.
Learn more →Our research
In 2,700+ runs, changing only the scaffold around a model moved it from 0 to 49 solved pentest challenges. How an agent behaves depends on the system around the model, so that is where we test and put controls.

Cyphlon
1:1 Consultation Call
30 min
Google Meet
An introductory call with our engineers about any engagement: a pentest, continuous testing, managed AppSec, security engineering, agentic AI security or a fractional CISO. We'll ask about your stack, your deadlines and what your customers or auditors expect, and tell you plainly if we're not the right fit.
