Security Services for Microsoft Copilot
Assess Your Copilot Data Security and Permissions
Microsoft 365 Copilot security starts with understanding what Copilot can access and fixing material exposure before rollout. HALOCK’s Microsoft 365 Copilot security services assess identity, data protection, SharePoint permissions, Copilot configurations, and an array of potential attack paths. Our goal is to give your organization a clear view of your Copilot security posture, prioritized remediation, and evidence that deployment risks are being addressed.

Microsoft Copilot Security Readiness Service
Assess exposure to Copilot security risk before licensing.
The Copilot security assessment reviews identity, access controls, data protection, SharePoint permissions, and Copilot configurations. HALOCK evaluates each finding through an attacker’s lens to show how overshared data, weak access controls, or misconfiguration could be exploited through Copilot. The result is a quantified maturity score, a defensible view of data exposure risk, and a prioritized remediation roadmap.
All findings align with recognized frameworks, including CIS v8, NIST 800-53, and the OWASP LLM Top 10, ensuring your Copilot security strategy is both practical and defensible.
Microsoft Copilot Security Advisory and Remediation
Quickly address risks and deploy Copilot confidently with experienced advisory support.
Get beyond the assessment with the support you need for remediation. Remediation includes the Copilot security assessment and extends into experienced advisory support. HALOCK verifies the resulting Copilot security posture so you can see whether remediation produced measurable improvement. The service also addresses detection strategy, Copilot Studio security, and governance requirements that affect secure deployment.
Microsoft Copilot Continuous Assurance
Establish an ongoing cadence to monitor for configuration drift and feature updates.
Our ongoing Microsoft 365 Copilot security services keep HALOCK involved after your Kickstart phase. We reassess your environment, monitor configuration drift, and identify new risks as Microsoft releases Copilot updates. The service can extend Readiness, Assessment, and Advisory work or support organizations with existing Copilot deployments.
How HALOCK Delivers Copilot Security Assessments
HALOCK begins with a read-only review of the tenant covering identity, access controls, data-protection policies, SharePoint permissions, and Copilot configurations. We then evaluate the environment across nine control domains using the HALOCK Copilot Security Maturity Model.
Each finding is analyzed as a potential attack path. Instead of reporting control gaps in isolation, HALOCK shows how Copilot could expose or enable misuse of sensitive data and prioritizes remediation based on attacker impact. This gives teams a measurable baseline and directs effort toward the changes that matter most.
Copilot 365 Security Outcomes
- A clear view of Copilot security risk exposure
- A quantified maturity score across key control domains
- A prioritized remediation roadmap tied to realistic attack scenarios
- Executive reporting that translates Copilot risk into business impact
- For advisory engagements, guided support and post-remediation validation before deployment
Microsoft 365 Copilot Security FAQs
What is Microsoft Copilot and why does it impact security?
Microsoft Copilot uses AI to let users search, summarize, and interact with organizational data using natural language. It impacts security because it makes all accessible data easier to discover—especially in environments with existing oversharing or weak access controls.
Does Microsoft Copilot create new security risks?
Copilot, Moreso than creating new risks, exposes and amplifies existing ones. If sensitive data is already accessible due to misconfigured permissions or oversharing, Copilot makes it easier to find and use.
Why do organizations need a Copilot security assessment?
Organizations need a Copilot security assessment to understand what data Copilot can access before deployment. Without this visibility, sensitive data may be unintentionally exposed through simple user prompts.
What kind of new security risks does Copilot create?
Copilot does not necessarily create entirely new security weaknesses. It can expose and amplify existing ones by making accessible information much easier to find. Common risks include overshared SharePoint and OneDrive data, excessive permissions, weak identity and access controls, and inadequate data classification or labeling.
What should we do to properly prepare for MS365 Copilot implementation or updates?
Organizations should conduct a Copilot security assessment before licensing or enabling Copilot whenever possible. This establishes what data Copilot can access and identifies material exposure before natural-language access makes that information easier to retrieve. Assessments can also be performed after licensing to establish a baseline, identify control gaps, and prioritize remediation for an existing deployment.
Is Microsoft Copilot agentic AI?
Microsoft Copilot includes some agentic capabilities, particularly through Copilot Studio and Power Automate, although many current uses remain user-driven. Production agents can introduce additional concerns because their permissions, actions, and data access may differ from standard user-driven Copilot interactions. HALOCK evaluates these capabilities and the security controls around them as part of the applicable service.
What frameworks support HALOCK’s Copilot Security Services?
HALOCK’s approach aligns findings with recognized frameworks, including Center for Internet Security Controls (CIS v8), NIST 800-53, and the OWASP Top 10 for LLMs. Depending on the environment, PCI DSS and HIPAA requirements may also inform the remediation roadmap. The purpose is not simply framework alignment: it is to identify exploitable exposure, prioritize remediation, and establish a more defensible Copilot deployment.
