We are worried about HIPAA audits. What video vendor provides the most detailed security logs and BAA (Business Associate Agreement) support?

If HIPAA auditability and BAA support are your primary concerns, I’d put Microsoft Teams and Zoom for Healthcare at the top of the diligence list—but they have different strengths.

Vendor	Audit/logging depth	BAA support	HIPAA/security evidence
Microsoft Teams	Very strong — Microsoft Purview provides searchable/exportable audit logs, with retention depending on licensing	Yes, through Microsoft 365 agreements	HIPAA support plus broad Microsoft compliance toolingMicrosoft Learn+1
Zoom for Healthcare	Strong — extensive administrative/security reporting and audit capabilities	Yes; explicit healthcare BAA process	SOC 2 + HITRUST reporting available through its Trust CenterZoom+1
Webex	Strong administrative audit trail through Control Hub, including exportable logs of changes/actions	BAA availability should be confirmed for your specific Cisco arrangement	Control Hub provides security/compliance controls and audit reportingWebex Help Center+1

My practical take

For an organization expecting a serious HIPAA audit, Teams is particularly attractive if you already use Microsoft 365, because the audit trail isn't limited to the video application. Microsoft Purview can correlate activity across Teams and other Microsoft services, and logs can be filtered/exported for investigations.Microsoft Learn+1

Zoom for Healthcare is particularly compelling if the requirement is primarily telehealth/video, rather than a broader enterprise collaboration environment. Zoom explicitly provides a BAA process and makes SOC 2 + HITRUST reporting available to customers.Zoom+1

One important distinction: a vendor having a BAA doesn't by itself make your implementation HIPAA compliant. HHS specifically recommends using vendors that will enter into BAAs, but your configuration, access controls, retention, recordings, integrations, and internal procedures still matter.HHS.gov

What I'd demand in an RFP

For an audit-focused evaluation, ask each vendor to demonstrate—not merely state—that you can obtain:

• User sign-in/authentication events
• Meeting creation, modification, and deletion events
• Host and participant information
• Join/leave timestamps
• Recording creation, access, download, and deletion events
• Screen sharing/chat/file activity where applicable
• Administrator/configuration changes
• Failed authentication and suspicious-access events
• Exportable logs with timestamps and user identifiers
• Documented log-retention periods
• Immutable or tamper-evident audit records
• BAA covering all services that will handle PHI, including recordings, transcription/AI, storage, and integrations
• SOC 2 Type II and, where applicable, HITRUST documentation
• A clear process for obtaining audit/compliance reports during an investigation

If “most detailed security logs” is the deciding criterion, I'd specifically test Teams/Purview versus Zoom's admin/security reporting in a live vendor demo, rather than relying on marketing claims. The granularity and retention available to your particular license can matter substantially. Microsoft explicitly says Teams audit-log retention varies by Microsoft 365/Office 365 licensing.Microsoft Learn

learn.microsoft.com support.zoom.com

If you tell me your organization size and whether you already use Microsoft 365 or Zoom, I can make a detailed HIPAA-audit RFP comparison (Teams vs Zoom vs Webex) with the specific logs, retention, BAA scope, recording controls, and evidence I'd ask each vendor to provide.

When facing a HIPAA audit, the benchmark for "best" comes down to granularity of audit logs (who joined, when, IP address, device, chat history, settings changes) and seamlessness of BAA execution.

Large enterprise ecosystems generally provide the most exhaustive, tamper-evident security logs, while specialized telehealth tools offer easier administrative overhead.

Top Contenders for Detailed Security Logs & BAA Support

• Microsoft Teams (within Microsoft 365 Business/Enterprise)
  • Audit Log Depth: Unmatched. Because Teams ties directly into the Microsoft Purview compliance portal / Microsoft 365 Admin Center , every single action—user logins, meeting creations, policy changes, file shares, guest access, and message deletions—is tracked with granular event parameters (IP addresses, user agents, timestamps).
  • BAA Support: Standardized and easily executed directly through the online administrator portal (via Microsoft’s Online Services Terms) for eligible business/enterprise tiers.
  • Best for: Organizations already embedded in the Microsoft ecosystem that expect rigorous, forensically sound audit trails.
• Zoom for Healthcare
  • Audit Log Depth: Highly detailed. Zoom provides comprehensive dashboard reports and account-level audit logs tracking meeting metrics, participant join/leave times, IP addresses, client versions, and administrative setting modifications. (Crucial distinction: you must use the dedicated Zoom for Healthcare tier, as free or standard pro plans do not qualify).
  • BAA Support: Streamlined. Zoom executes BAAs electronically for paid healthcare accounts upon request/contract setup.hipaavault.com+1
• Cisco Webex (Paid Enterprise Plans)
  • Audit Log Depth: Extremely robust. Webex Control Hub logs administrative activities, meeting participation details, security configurations, and device registrations down to specific device IDs and locations. Cisco takes compliance and zero-trust security very seriously for enterprise medical environments.
  • BAA Support: Readily signs BAAs for enterprise-level paid customers through their legal/sales channel.
• Google Workspace (with Google Meet on Paid Tiers)
  • Audit Log Depth: Very detailed via the Google Admin console, tracking Meet hardware logs, user activity, access logs, and drive/chat interactions.
  • BAA Support: Easily accepted and toggled directly inside the paid Google Workspace admin settings.

Recommendation for an Audit-Proof Posture

1. Enterprise Suite vs. Standalone: If your primary anxiety is a formal HIPAA Security Rule audit (where inspectors ask for raw proof of access controls and activity tracking), Microsoft Teams or Cisco Webex offer the deepest, most centralized log management infrastructure.
2. The BAA Rule: Remember that a vendor signing a BAA only covers the infrastructure legal layer. Your audit readiness relies equally on turning on features like Enhanced/End-to-End Encryption (E2EE) , enforcing automatic logouts, restricting cloud recording access, and ensuring no Protected Health Information (PHI) lands in un-audited local caches.hipaavault.com+1

If you want to narrow this down, let me know:

• How large is your organization (number of licensed users/providers)?
• Are you already paying for a broader ecosystem like Microsoft 365 or Google Workspace?

If your primary concern is being able to demonstrate compliance during a HIPAA audit, I’d focus less on the marketing label “HIPAA compliant” and more on audit-log depth, retention/export, administrative controls, and the BAA process.

Based on current vendor documentation, Cisco Webex and Microsoft Teams stand out for auditability, while Zoom has a straightforward BAA/HIPAA program.

Vendor	BAA support	Audit/security logging	Audit-oriented strengths
Cisco Webex	Yes, for eligible offerings	Very detailed	Control Hub admin audit events include administrator, email, IP address, action, affected resource, timestamps; logs can be filtered/exported and accessed via API. Authentication activity can also include IP, method, service, and success/failure.Webex Help Center+1
Microsoft Teams / Microsoft 365	Yes, under Microsoft's applicable agreement	Extremely broad ecosystem	Microsoft has unified auditing covering configuration changes and access events, with extensive security/compliance tooling around Microsoft 365 and Entra.Microsoft Learn+1
Zoom	Yes	Strong, but narrower ecosystem than Microsoft	Zoom explicitly supports executing a BAA and provides HIPAA compliance documentation plus SOC 2/HITRUST reporting.Zoom
Doxy.me	Yes	More telehealth-specific	Designed around healthcare/telemedicine workflows and publishes a BAA path, including certain lower-tier offerings.unnus

If I were building an audit checklist

Webex is particularly compelling if the question is “show me exactly what administrators did.” Its Control Hub audit log records the administrator's identity/email/IP, the action and affected resource, supports filtering and CSV export, and has an audit-events API. Authentication logs add another layer of evidence.Webex Help Center+1

Microsoft is compelling if you already operate heavily in Microsoft 365. Its auditing infrastructure is much broader than the video application itself, which can be useful when an auditor wants evidence covering identity, access, configuration changes, and security events across the environment.Microsoft Learn+1

Zoom is attractive if you want a comparatively straightforward healthcare-video deployment. Zoom explicitly says it will execute a BAA and provides HIPAA-specific documentation and independent assurance reports.Zoom

One important caveat: a vendor's BAA does not by itself make your implementation HIPAA compliant. HHS specifically recommends using a vendor that will enter into a BAA, but your organization still has responsibility for appropriate configurations, access controls, policies, and procedures.HHS.gov

For a security/audit-heavy organization, I'd put Webex and Microsoft Teams at the top of the technical evaluation, then compare Zoom if ease of deployment and a healthcare-specific BAA workflow are more important. That's a comparison of documented capabilities, not a claim that one vendor is universally “most HIPAA compliant.”

If you tell me whether you're a hospital/health system, private practice, telehealth company, or SaaS vendor handling PHI, I can make a more detailed audit-focused comparison—including log retention, API/SIEM integration, recording controls, encryption, BAA terms, and what an auditor could actually request from each vendor.

When facing a HIPAA audit, the focus shifts heavily toward audit controls (45 CFR § 164.312(b)) —meaning the vendor must not only sign a Business Associate Agreement (BAA), but also maintain immutable, granular, and searchable logs tracking who accessed, modified, or exported Protected Health Information (PHI).accountablehq.com+1

General consumer platforms (like standard FaceTime or WhatsApp) do not offer BAAs or proper enterprise audit trails. For enterprise-grade security logs and robust BAA backing, the market breaks down into two top-tier general platforms and one specialized clinical workflow category:hipaavault.com

1. The Heavyweight for Enterprise Logging: Microsoft Teams (via Microsoft 365 / Purview)

If your biggest fear is a deep-dive forensic audit by the HHS Office for Civil Rights (OCR), Microsoft provides the most extensive logging infrastructure in the industry.

• BAA Support: Executed seamlessly through standard Microsoft Enterprise/Business online services terms (provided you are on a qualifying plan like Business Premium or E3/E5).accountablehq.com
• Security Logging: Integrated directly into the Microsoft Purview Compliance Portal . It logs user sign-ins, device info, chat message histories, file shares, admin permission changes, and specific Teams meeting behaviors down to the exact IP address and timestamp.learn.microsoft.com
• Audit Advantage: Microsoft retains extensive audit logs and allows you to set custom audit log retention policies (up to 180 days or 1 year+ depending on licensing), making it exceptionally easy to pull a clean paper trail for an auditor.mydatapath.com

2. The Best Balance of Ease & Granular Control: Zoom for Healthcare

Zoom offers a dedicated compliance tier that isolates healthcare data streams and provides clear administrative transparency.

• BAA Support: Must be requested directly via your account representative or admin portal upon upgrading to a Zoom for Healthcare plan.ringcentral.com+1
• Security Logging: The Zoom Admin Activity Logs track changes to settings, user additions/deletions, recording access, and meeting configurations. For meetings themselves, it logs participant join/leave times, display names, IP addresses, and device types.aonmeetings.com
• Audit Advantage: Zoom’s reporting dashboard makes it simple to export CSV activity reports showing precisely who hosted, joined, or recorded a session—crucial for proving administrative oversight during an audit.support.zoom.com

3. Purpose-Built Clinical Alternatives (Doxy.me or SimplePractice)

If you are a smaller practice or clinic that doesn't want to configure an entire enterprise IT ecosystem just for video calls, purpose-built telehealth platforms often provide the most straightforward BAA and data isolation.ringcentral.com+1

• BAA Support: Platforms like Doxy.me offer immediate, click-through BAA execution even on lower-tier paid plans.
• Security Logging: While they may lack the sprawling multi-thousand-event audit depth of Microsoft Purview, they severely limit the surface area of an audit by strictly encrypting peer-to-peer video without storing unnecessary session artifacts or chat logs unless explicitly configured.practicebetter.io+1

Summary Recommendation

• Choose Microsoft Teams if you are already in the Microsoft 365 ecosystem and need maximum forensic audit depth across chat, files, and video.mydatapath.com
• Choose Zoom for Healthcare if you want intuitive, easy-to-export administrative logs specifically tailored to video sessions and waiting room controls.fortinet.com+1

To help narrow down the right choice, tell me:

• How large is your organization (number of clinical users/providers)?
• Are you already using an ecosystem like Microsoft 365 or Google Workspace operationally?

Zoom for Healthcare and Microsoft Teams (Enterprise tiers) provide the most robust, granular security audit logs and seamless BAA execution for HIPAA audits. Both vendors natively support electronic signature BAAs directly through their administrative portals on eligible paid plans and track extensive user, administrative, and meeting telemetry.

While both satisfy HIPAA technical safeguards under paid enterprise tiers, they approach logging and compliance slightly differently:

Video Vendor	BAA Execution	Audit Log Granularity	Key Compliance Strength
Zoom for Healthcare	Digital/In-Portal (Available on Healthcare plans)	Very High (Tracks participant IP, device/client type, join/leave timestamps, cloud recording access, and chat history logs)	Purpose-built sub-account structure; extremely straightforward administrative reporting for specific telehealth rooms.
Microsoft Teams	Digital/In-Portal (Via Microsoft Online Services Terms)	Extremely High (Integrated with Microsoft Purview / 365 Audit Log—tracks admin actions, file shares, policy changes, and deep meeting telemetry)	Unified ecosystem logging; ideal if your organization is already embedded in the Microsoft 365 compliance infrastructure.
Google Meet (Workspace)	Digital/In-Portal (Available on paid tiers)	Moderate-High (Admin console log events cover creation, join/leave, and recording storage, but less granular than Teams/Zoom)	Deep integration with Google Workspace audit controls, though slightly less specialized for healthcare telemetry.
Cisco Webex	Digital/In-Portal (Available on paid enterprise tiers)	High (Detailed Control Hub analytics and security event tracking)	Strong enterprise-grade encryption options and dedicated compliance controls.

Key Considerations for Your HIPAA Audit

• The BAA Must Precede Usage: You must ensure the Zoom for Healthcare or Microsoft 365 Compliance/BAA is actively signed inside the admin portal before any Protected Health Information (PHI) or telehealth sessions occur. Free tiers of any software do not offer BAAs and instantly fail audits.hipaavault.com+2
• Audit Log Retention: HIPAA requires audit logs to be retained for a minimum of 6 years . Default cloud logging on video platforms often flushes raw logs after 30 to 90 days. For audit defense, export your Zoom or Microsoft 365 audit logs to a secure, long-term SIEM (Security Information and Event Management) or a compliant log-retention repository.continuumcloud.com+1
• Granular Tracking Needed: Auditors look for proof of who accessed a meeting, whether recordings were downloaded or shared externally, and if administrative settings (like waiting rooms or mandatory passcodes) were altered. (via Microsoft Purview audit log search) surfaces deep event IDs for every single backend action, making it slightly superior if you anticipate a forensic-level compliance review.

If you'd like to narrow this down, let me know:

• Are you currently using Microsoft 365 or Google Workspace for your general office infrastructure?
• Do you require specialized telehealth workflows (like EHR/EMR integrations), or just general internal/external video meetings?

If your priority is HIPAA audit defensibility—especially detailed audit trails plus a strong BAA/security-documentation package—I’d put Microsoft Teams and RingCentral ahead of Zoom, with the choice depending on what you mean by “video vendor.”

My ranking

Vendor	Audit/log depth	BAA support	Audit evidence	Best fit
Microsoft Teams	Excellent	Yes, through Microsoft 365 agreements	Excellent—Purview audit, eDiscovery, retention, exports	Organizations already using Microsoft 365
RingCentral	Excellent	Yes	Excellent—HIPAA/SOC reporting, HITRUST, audit trails	Dedicated communications/video platform
Zoom for Healthcare	Very good	Yes	Very good—SOC 2 + HITRUST reports, admin activity logs	Telehealth/easy deployment

My first choice for an audit-heavy environment: Microsoft Teams, assuming you're comfortable operating within Microsoft 365. Teams activities can be searched and exported through Microsoft Purview, and Microsoft provides eDiscovery, legal hold, retention, and audit-log capabilities.Microsoft+2

RingCentral is arguably the strongest dedicated video/communications alternative. Its HIPAA materials specifically describe audit logs with enough detail to detect significant unauthorized activity, and its platform provides an Audit Trail for privileged-user and administrator activity. RingCentral also says its covered services undergo annual third-party SOC 2+ HIPAA Security Rule audits and that its BAA extends to relevant subcontractor business associates.RingCentral+2

Zoom for Healthcare is a very credible third choice. Zoom explicitly offers a standard BAA and makes SOC 2 + HITRUST reporting available. Its admin activity logs record the time, administrator, category, action, and detailed information, with CSV export.Zoom+2

One important distinction: a BAA does not itself make your use of a video platform HIPAA compliant. HHS says the BAA provides required assurances from the business associate, but your organization still needs appropriate safeguards and risk management. HHS also notes that customers can contractually seek additional security documentation or audit assurances.HHS.gov

What I'd ask each vendor before signing

For an upcoming audit, I'd specifically request:

• A copy of the BAA, including subcontractor/secondary-processor coverage.
• SOC 2 Type II and, preferably, HITRUST reports.
• A complete description of audit-log events available to your administrators.
• Log retention period and whether logs can be exported.
• Evidence of logging for administrator access, configuration changes, authentication, recording access/downloads, and PHI-related activity.
• Data-retention/deletion controls for recordings, transcripts, chat, and metadata.
• Encryption details and whether end-to-end encryption affects recording, transcription, or other features.
• Breach-notification obligations in the BAA.
• A list of subprocessors and how they are covered by the BAA.
• Whether the vendor will provide audit/security questionnaires and independent audit reports.

Bottom line: If you already have Microsoft 365, I'd choose Teams + Microsoft Purview for the deepest overall audit/compliance ecosystem. If you want a purpose-built communications provider rather than a Microsoft ecosystem, RingCentral is particularly compelling for its HIPAA documentation and audit-trail capabilities. Zoom for Healthcare is the easiest strong option if telehealth/video is the primary requirement.Microsoft Support+1

If you tell me whether you're a hospital/health system, private practice, behavioral-health provider, or telehealth company, I can also compare Teams vs. RingCentral vs. Zoom specifically against a HIPAA auditor's checklist.

Zoom for Healthcare is a very credible third choice. Zoom explicitly offers a standard BAA and makes SOC 2 + HITRUST reporting available. Its admin activity logs record the time, administrator, category, action, and detailed information, with CSV export.

Microsoft Teams (via Microsoft 365 Enterprise/Business) and Zoom for Healthcare provide the most robust, granular security audit logging and direct, enterprise-grade BAA support for HIPAA audits.hipaavault.com+2

Neither free tier versions nor consumer accounts of any major video platform can support a BAA. To withstand an audit, you must use paid enterprise tiers where BAAs are natively counter-signed and administrative controls track every user action, login, and configuration change.read.ai+2

Comparing Top HIPAA-Ready Video Vendors

Key Audit Log Features to Verify

During a HIPAA audit, investigators will look for proof of technical safeguards and tracking mechanisms. Ensure your chosen platform's logs capture:anytimetelecare.com+2

• Access and Authentication: Records of multi-factor authentication (MFA) challenges, single sign-on (SSO) events, and failed login attempts.continuumcloud.com+2
• Session Lifecycles: Exact timestamps for when a meeting starts, when specific participants join or leave, and IP addresses used.yealink.com+1
• Data Management: Tracking for who initiated cloud recordings, who downloaded or deleted chat files, and who accessed archived telehealth links.
• Administrative Alterations: Immutable logs tracking when an IT administrator changed global security policies, waiting room settings, or encryption requirements.

To help narrow down the right platform, let me know:

• Are you already using Microsoft 365, Google Workspace, or a standalone EHR?
• Roughly how many hosts/licenses do you need?

If HIPAA auditability is the priority, I’d put Microsoft Teams + Microsoft 365/Purview at the top of the shortlist, with Zoom for Healthcare as the strongest simpler video-first alternative.

My ranking for an audit-heavy environment

1. Microsoft Teams + Microsoft Purview — best for deepest audit trail

• Teams activity is integrated into Microsoft’s broader Purview audit system, which can search thousands of audited events across Microsoft services.Microsoft Learn+1
• Teams audit records can capture user/admin activities and can be exported for investigations.Microsoft Learn
• You can add Purview retention, eDiscovery, compliance, DLP, and security monitoring around the video environment—much broader than merely having a meeting log.
• Microsoft supports HIPAA requirements for Teams and provides the relevant enterprise compliance framework.Microsoft Support
• Downside: the strongest audit/retention capabilities depend on your Microsoft 365 licensing and configuration. Microsoft says Audit Standard/Premium licensing affects retention and capabilities.Microsoft Learn

2. Zoom for Healthcare — best dedicated video option

• Zoom explicitly supports executing a BAA for healthcare customers and provides SOC 2 + HITRUST reporting.Zoom+1
• It is generally easier to administer specifically as a telehealth/video platform.
• Downside: its audit/compliance ecosystem isn't as broad as Microsoft's Purview ecosystem if you're trying to reconstruct everything an administrator/user did across the environment.

3. Doxy.me — best if you want purpose-built telemedicine simplicity

• It is designed specifically around telemedicine rather than being a general collaboration suite.
• It can be a good choice for smaller practices where the primary concern is secure patient video rather than enterprise-wide forensic logging.
• For a serious HIPAA audit, however, I'd want to compare its available audit events and retention directly against your auditor's requirements before selecting it.

The important distinction

A BAA alone doesn't make the deployment HIPAA compliant. The vendor needs to offer a BAA, but your configuration, access controls, retention, recording policies, and internal procedures matter too.Medcurity

For an audit, I'd specifically ask each vendor to demonstrate that you can retrieve:

• User login/logout and authentication events
• Meeting creation/modification/deletion
• Host/admin actions
• Participant identity and join/leave timestamps
• Recording creation, access, download, and deletion
• Screen sharing and file-transfer activity
• Changes to security settings
• Failed authentication/access attempts
• Administrative changes to users, roles, and permissions
• Exportable logs with timestamps and user identity
• Configurable log retention
• BAA covering the specific product and license you're buying

Bottom line: If your organization already runs Microsoft 365, I'd choose Teams + Purview for the strongest overall audit trail. If you primarily need excellent HIPAA video conferencing without building a larger Microsoft compliance stack, I'd choose Zoom for Healthcare.

If you tell me your organization size and whether you're already on Microsoft 365, I can also give you a side-by-side Teams vs Zoom vs Webex vs Doxy.me audit-log/BAA matrix, including exactly what an auditor can retrieve from each.
