Cencurity is an LLM security gateway designed to protect enterprise AI agents from data leakage and unauthorized access. It sits as a proxy between your LLM calls and the models, inspecting every request and response for sensitive data and risky code patterns. This tool is built for development teams that rely on AI coding assistants like Cursor or Copilot, as well as custom agent workflows. Its core value lies in providing real-time protection without requiring any changes to existing code—just plug it in and instantly gain visibility and control over all agent traffic.
The primary problem Cencurity solves is the inherent risk of prompt leakage and sensitive data exposure when using LLMs in production. Developers often inadvertently send secrets, PII, or proprietary code to third-party models, while agents can generate harmful or confidential output. This creates compliance nightmares, especially under regulations like SOC2, HIPAA, or GDPR. Without a gateway, teams have no centralized way to monitor what goes in and out of their LLM calls, making it nearly impossible to enforce policies consistently across different models and IDEs. Cencurity addresses this by becoming the single control point for all agent communication.
One of the standout features is the Centralized Security Dashboard, which offers a single pane of glass for every agent call. This dashboard displays real-time metrics such as request count, response latency, policy hits, redactions, and blocks. You can see exactly when a secret was detected or a risky output was stopped, along with the full context of the interaction. This eliminates the need to manually sift through scattered logs or rely on incomplete monitoring. By providing instant visibility, it allows security teams to spot anomalies and refine policies quickly, reducing the window of exposure.
Real-time protection is another critical feature that automatically detects and blocks secrets, PII, and risky output before they reach users or models. Cencurity uses pattern-based and machine-learning detection to identify credit card numbers, API keys, passwords, and other sensitive data. When a leak is detected, the gateway can either mask the sensitive content or block the entire request/response, depending on your policy. This edge-based enforcement ensures that data never leaves your controlled environment without meeting your security rules, giving you confidence even when interacting with external AI providers.

Real-time log analysis complements protection by tracing every agent interaction end-to-end. You can search, filter, and correlate requests, responses, and policy decisions to pinpoint risk in seconds. For example, if a user reports unexpected behavior, you can quickly find the exact calls that triggered a policy violation and see what was redacted. Additionally, Cencurity supports webhook notifications that send verified alerts to Slack, Jira, or other tools, ensuring that your team is immediately aware of any policy breaches. The dry-run rollout feature lets you test new policies in a non-blocking mode, measuring impact before enforcement.
The product works as a lightweight proxy that you deploy alongside your existing applications. It intercepts HTTP requests to and from LLM providers, applying a set of configurable policies. These policies are written as simple rules that define what to detect (e.g., regex patterns for secrets) and what action to take (log, mask, or block). Cencurity also provides pre-built policies for common use cases like PII redaction. The whole setup integrates directly with your IDE workflow—simply point your agent to the Cencurity endpoint, and all traffic is filtered. There is no need to rewrite existing agent code or modify your model prompts.
Concrete use cases include logging every agent call to a central dashboard for audit trails, enabling zero-click protection that automatically blocks secrets without developer intervention, and sending real-time webhook alerts when a policy is triggered. For instance, a development team can enable dry-run mode first to see how many false positives a new policy generates, then switch to enforcement once confident. This allows safe rollout of security measures without breaking existing functionality. In production, the dashboard provides evidence for compliance auditors, showing exactly what data was redacted or blocked and when.
Cencurity is built for developers and security teams who need safe, governed AI coding with speed. It is compatible with any LLM agent and any IDE, including Cursor, Copilot, and custom toolchains. The software is open-source and available on GitHub under a quickstart guide that gets you up and running in minutes. While pricing details are not explicitly listed, the free tier allows immediate use. The target audience includes DevOps engineers deploying AI agents, security analysts enforcing policies, and compliance officers requiring audit-ready logs. Ultimately, Cencurity provides peace of mind by ensuring that every LLM interaction is protected, traceable, and compliant.
