Use AI in a responsible and transparent way, with clear boundaries and visibility. We help you stay in control of Copilot and custom AI agents by managing access, permissions, and data usage to reduce the risk of misuse or leakage. From prompt to action, AI workflows remain aligned with security, compliance, and business intent without unexpected side effects.
Reduce cloud risk through consistent baselines and continuous visibility. We help you understand configuration drift, exposure, and misconfigurations across cloud environments, and detect deviations early. This keeps risk under control as cloud footprints grow and architectures evolve, without slowing down innovation.
Improve application security without disrupting business workflows. We provide visibility into permissions, secrets, and API access across SaaS and enterprise applications, helping detect risky behaviour, misconfigurations, and excessive privileges. This reduces application risk while keeping systems usable and reliable.
Protect sensitive data through clear classification, labeling, and policy-based controls. We help regulate access, sharing, and data loss across Microsoft 365 and cloud workloads, while tracking how data is used throughout its lifecycle. This reduces both accidental exposure and intentional misuse.
Maintain strong endpoint security with minimal user friction. We use the full capabilities of Microsoft Intune and Defender for Endpoint to continuously assess device posture, exposure, and compliance across platforms. Threats are detected early, compromised devices are immediately isolated, and security standards remain consistent — while users stay productive and supported.
Secure access using practical Zero Trust principles and continuous risk evaluation. We help apply Conditional Access, strong authentication, and least-privilege access across users and workloads, while monitoring identity behavior. This reduces identity-driven attack paths and supports modern ways of working.
Security Copilot only adds value when it's properly guided and tuned.
We build custom agents using structured queries, instructions, and prompt books.
The result: concise, consistent outputs aligned with your environment and workflows.
