Key Points
Compliance monitoring in Microsoft Teams is essential for safeguarding sensitive data, reducing cybersecurity risks, and maintaining regulatory adherence through tools like Microsoft Purview and third-party solutions like Mimecast Aware.
Challenges in Teams compliance include managing unstructured data, mitigating risks from sensitive data sharing, and addressing compliance gaps in third-party integrations, which require proactive monitoring, clear policies, and regular employee training.
Ensuring regulatory compliance in collaboration tools like Microsoft Teams is no longer a nice-to-have. With the rise in remote work, and fines for improper record-keeping in these tools exceeding $1.7 billion since 2021, ensuring compliance in this data set is now a critical aspect of organizational governance. Read on to explore the intricacies of compliance monitoring in Microsoft Teams and why it is indispensable for modern companies.
What is compliance monitoring in Microsoft Teams?
Compliance monitoring for Microsoft Teams involves tracking, enforcing, and documenting adherence to regulatory and internal policies within the platform’s ecosystem. A dedicated compliance function ensures that data handling, storage, and sharing align with legal requirements and company standards.
In Teams, compliance monitoring isn’t just ticking off a regulatory checklist, but an active, ongoing process to protect sensitive data, maintain accountability, and mitigate risks tied to real-time communication and collaboration. The unstructured, high-volume nature of Teams data—spanning chat, meetings, files, and integrations—makes effective monitoring a key factor in a strong compliance posture.
Microsoft Teams security features
Microsoft Teams includes multiple layers of security controls to help safeguard sensitive communications and data:
Data encryption: Encrypts data both in transit and at rest to protect against unauthorized access.
Multi-factor authentication (MFA): Ensures that only authorized users gain access to the platform, even if credentials are compromised.
Compliance certifications: Teams meets standards like HIPAA, ISO 27001, SOC 1 and SOC 2, and GDPR, supporting regulated industries in meeting their obligations.
Information barriers: Restricts communication between specific groups or individuals to prevent unauthorized sharing of information.

Advanced threat protection: Detects and blocks malicious content, links, and attachments before they can be acted upon.
These built-in protections work best when paired with clear policies, regular monitoring, and user awareness programs.
Why Microsoft Teams compliance matters
Organizations across regulated and unregulated industries store and transmit vast amounts of sensitive information in Teams, including:
Financial data: governed by SEC and FINRA rules
Protected health information (PHI): subject to HIPAA requirements
Personally identifiable information (PII): subject to GDPR, CCPA, and other privacy laws
Payment card data: subject to PCI DSS compliance requirements
Compliance monitoring helps organizations:
Safeguard sensitive data and ensure privacy obligations are met.
Reduce cybersecurity risks by detecting and addressing risky behaviors in real time.
Avoid costly fines and reputational damage from non-compliance.
Build a culture of accountability where employees understand and follow data handling rules.
Regulatory bodies increasingly expect continuous compliance—not just policy creation. Demonstrating adherence in Microsoft Teams requires visibility into user activity, especially in chat and file-sharing spaces where even administrators may have limited insight.
Strengthen your Microsoft Teams compliance with advanced tools built to withstand the data deluge.
What tools can I use for Microsoft Teams compliance?
There are tools available within the Microsoft suite that enable organizations to monitor Teams.
Microsoft Teams Admin Center
The Teams Admin Center has a centralized dashboard where administrators can monitor important metrics like members, owners, guests, Teams user classifications, team status, group chats, private chats, Teams channels, Teams rooms, and meetings. Usage reports highlight Teams app and device usage, audio and video conferencing, live events, virtual appointments, SMS notifications, and more.
Teams usage report
This is a built-in report within the Teams Admin Center. It provides a view of how users leverage Teams, including employee activity metrics like the number of users per device type, user count per activity type, and activity counts.
Microsoft 365 usage analytics
This tool also monitors Microsoft Teams usage data as well as performance metrics, alarms, and Microsoft Teams service status. Admins can spot adoption trends that may equate to performance issues.
Microsoft purview compliance portal
This portal can be used to monitor Microsoft Teams for security and compliance purposes. Purview gathers data from custodians across all of Microsoft 365’s ecosystem as primarily an eDiscovery tool rather than compliance monitoring.
Audit log
The audit log records global admin and user activity reports, allowing Teams administrators to monitor actions and changes made and identify potential non-compliance and internal policy violations.
Third-party apps
Third-party solutions like Mimecast Aware offer advanced monitoring capabilities for Teams, like usage analytics, performance monitoring, resource availability, security scanning, and customizable dashboards. Such platforms can make compliance monitoring work in Teams and other platforms organizations use to collaborate.
What compliance standards does Microsoft Teams use?
Microsoft Teams supports and adheres to various compliance standards to ensure a secure and compliant collaboration environment.
Compliance standards for Teams
Microsoft Teams supports many compliance standards, including:
HIPAA
ISO 27001
ISO 27018
SSAE16
SOC 1 and SOC 2
Organizations can further manage their data governance using Microsoft Purview (formerly Azure Purview, available with an active Microsoft 365 license for an additional cost). Using Purview, compliance officers can better understand how data moves through their organization, where risks exist, and deploy controls that enforce best practices and acceptable use.
Compliance challenges when using Teams
Despite its many benefits, using Microsoft Teams for collaboration poses unique challenges related to compliance:
Complex file storage and searchability—Files linked within Teams chats can be difficult to locate within the complex environment of public and private channels and direct messages and cloud-based storage locations like SharePoint, OneDrive, and OneNote, making it harder to understand where sensitive or regulated data lives
Sensitive data sharing—That employees share sensitive data at all within Teams is both an indisputable fact and a major information security headache—impacting search and eDiscovery, internal forensic analysis and early case assessment, knowledge management, and data loss prevention in addition to compliance
Exfiltration and message modification—Teams can offer employees an attractive solution to circumvent traditional controls and checkpoints, for example by sharing restricted content and removing the message to hide evidence of having done so. This constantly changing, real-time flow of unstructured data requires a new approach for compliance teams to manage
Third-party compliance gaps—Teams offers thousands of integrations with custom and third-party apps and tools, each one creating a potential backdoor through which data can be compromised
Steps to reduce compliance risks in Teams
To mitigate compliance risks associated with Teams, organizations can take some simple but effective steps, including:
Creating clear acceptable use policies for Teams
Regularly training employees on compliance risks and best practices
Setting appropriate retention periods for all Teams data
Using monitoring tools to track Teams activity and ensure compliance
Collaboration tools like Microsoft Teams provide powerful new ways for employees to work together to achieve business goals and accelerate workflows, but the chatty, informal nature of collaborative work can make it more tempting to circumvent rules. Our research shows that employees are far more willing to share sensitive information such as credit card numbers in collaboration tools than they would be in legacy systems such as email.
Educating employees on the risks inherent in these behaviors, and providing secure channels where employees can exchange company-sensitive information, is essential to mitigating this danger in Teams. Pairing routine employee education and training with a tool like Aware that can monitor compliance and correct employees in real time can further support compliance adherence and data security for Microsoft Teams.
