CellTrust’s SL2 is now listed in Microsoft AppSource and the Microsoft Teams store, bringing its enterprise-grade mobile messaging capture and compliance tooling directly into the Microsoft collaboration stack and making it easier for regulated organisations to deploy mobile communications capture inside Microsoft Teams. The move packages SMS, WhatsApp and Teams messaging capture with automatic archiving into Microsoft 365 compliance stores, Entra ID single sign‑on, and optional Intune management—positioning SL2 as a turnkey option for banks, broker-dealers, government agencies and other regulated enterprises that must record and govern mobile conversations. (appsource.microsoft.com, celltrust.com)
CellTrust SL2 has been a market presence for several years as a specialist platform that captures SMS, MMS, WhatsApp and voice communications for regulatory recordkeeping, eDiscovery and supervision. The vendor has progressively deepened integrations with Microsoft technologies—SL2 can push captured mobile communications into Microsoft 365 mailboxes for retention and discovery, integrate with Microsoft Purview tools, leverage Entra ID for authentication, and operate alongside Intune for endpoint controls. Those integrations are now formally surfaced through marketplace availability in Microsoft AppSource and the Teams store, lowering procurement friction and making SL2 discoverable to Microsoft-centric IT buyers. (celltrust.com)
This announcement is not a product reinvention so much as a strategic distribution and packaging step: by joining Microsoft AppSource and the Teams Store, CellTrust shortens the path from evaluation to trial and makes the SL2 Teams experience explicitly discoverable to organisations already standardised on Microsoft 365 and Teams. The AppSource listing describes features, licensing expectations and the requirement for an active CellTrust SL2 account—important operational details for procurement and implementation teams. (appsource.microsoft.com)
However, buyers should compare total cost of ownership and integration risk against alternatives that provide tighter coupling with existing archivers or that are delivered as part of a vendor’s larger compliance suite. For some organisations, building a custom ingestion pipeline into Purview from carrier capture or a managed service may be preferable if deep customisation or on‑prem storage is required. (celltrust.com, appsource.microsoft.com)
That said, the benefits come with clear caveats: privacy and BYOD policies must be treated seriously; moderation AI requires careful tuning and governance; and data residency, archiver compatibility, and contractual exit terms must be validated before wide deployment. A recommended approach is a staged rollout: pilot SL2 with a limited, representative cohort; validate archiver ingestion and Purview searchability; tune moderation rules and human review queues; and expand only after legal, security and HR stakeholders sign off. (helpnetsecurity.com, celltrust.com)
For Windows and Microsoft administrators tasked with compliance, SL2’s marketplace availability reduces procurement friction and creates an accessible path to evaluate whether native Teams‑embedded mobile capture can replace or supplement existing capture workflows. The integration with Microsoft Purview and Entra ID makes it a sensible candidate for firms aiming to centralise governance and reduce tool sprawl—provided the organisation performs the due diligence outlined above and treats moderation, privacy and data residency as first‑class items on the deployment checklist. (celltrust.com)
CellTrust SL2’s arrival in Microsoft AppSource and the Teams Store is a practical signal: mobile messaging compliance has moved closer to the mainstream Microsoft ecosystem, and organisations that must govern mobile channels now have a more direct, Microsoft‑aligned path to do so. The technical and legal details remain organisation‑specific, but marketplace availability removes an important barrier to evaluation and should accelerate adoption cycles where Microsoft is already the compliance backbone.

What SL2 brings to Microsoft Teams: features and capabilities
SL2’s Teams-enabled offering combines a feature set designed for regulated communications with integration hooks to Microsoft compliance tooling. Key capabilities include:- In‑Teams SMS and WhatsApp messaging: Users can send and receive SMS and WhatsApp conversations from within Microsoft Teams (desktop and mobile), while those messages are captured for compliance. (appsource.microsoft.com, celltrust.com)
- Automatic archiving into Microsoft 365: Captured messages can be routed to Microsoft 365 E5 mailboxes or otherwise integrated with Microsoft Purview (retention, Advanced eDiscovery, Communication Compliance). This enables established Microsoft retention and supervision workflows to operate over mobile messaging. (celltrust.com)
- Microsoft Entra ID SSO and Outlook contact sync: Users authenticate with work accounts via Entra ID and can sync Outlook contacts for a unified experience. (celltrust.com)
- Support for One‑to‑One, Group, BCC and WhatsApp messaging: The product supports several message modalities commonly used in client communications. (celltrust.com)
- Integration with EIA/archivers and optional moderation: SL2 offers automatic archiving to established electronic information archivers and optional content moderation/quarantine features that flag or hold risky messages for compliance review. Recent additions include AI‑based moderation capabilities designed to prevent high‑risk messages from being delivered. (appsource.microsoft.com, helpnetsecurity.com)
- BYOD and corporate device models: SL2 supports App Capture (BYOD), Carrier Capture and Stacked Capture strategies, allowing organisations to choose between separation of work/personal communications and enterprise control of numbers and archiving. (celltrust.com)
How it integrates with Microsoft technologies
CellTrust has intentionally aligned SL2 with Microsoft’s security, identity and compliance stack:- Microsoft Entra ID (Azure AD) is used for authentication and single sign‑on, simplifying identity management and conditional access. (celltrust.com)
- Captured communications can be handed off to Microsoft 365/E5 mailboxes or managed via Microsoft Purview Data Lifecycle Management, enabling organisations to apply the same retention and eDiscovery policies used for email and Teams content. (celltrust.com)
- Intune (Microsoft Endpoint Manager) integration allows SL2 to be deployed under UEM policies—important for BYOD/COPE/COBO rollouts where device controls, remote wipe and app protection policies matter. (celltrust.com)
- The AppSource and Teams Store listings mean organisations can discover, trial and (in some cases) transact for SL2 through Microsoft’s marketplaces—streamlining procurement and allowing Microsoft partner channels to include SL2 in solutions. (appsource.microsoft.com, techcommunity.microsoft.com)
Real‑world use cases and target industries
CellTrust positions SL2 primarily for heavily regulated sectors where mobile communications are both common and auditable:- Financial services and capital markets: Broker‑dealers, asset managers and wealth firms subject to SEC, FINRA, CFTC and similar regimes can capture advisor‑client SMS/WhatsApp and retain records under required retention schedules. (celltrust.com, fintechfutures.com)
- Government and public sector: Agencies that must meet public records requirements can use SL2 to ensure mobile interactions are captured and discoverable for FOIA and records law compliance. (celltrust.com)
- Healthcare and insurance: Where HIPAA or other privacy‑sensitive communications occur over mobile channels, SL2 provides the logging and archiving necessary for audits and investigations. (celltrust.com)
- Legal and professional services: Any firm that needs an exhaustive communication trail for client advice or regulatory proofs will find value in consolidating mobile interactions into corporate compliance systems.
Deployment, licensing and operational considerations
- Active account and licensing: The AppSource listing and vendor communications make clear that SL2 requires an active CellTrust SL2 account and licence—marketplace availability does not eliminate the need for vendor contracts. (appsource.microsoft.com, celltrust.com)
- Procurement path: AppSource and the Teams Store act as discovery and trial channels; enterprise licensing, contractual terms and data residency options are still negotiated with CellTrust directly. (appsource.microsoft.com, fintechfutures.com)
- Data residency and Azure regions: SL2 is engineered on Microsoft Azure with options for Azure Global and, in some cases, Azure Government clouds—organisations with strict residency or sovereign requirements should validate where captured content will be stored and whether a government cloud instance is available. (celltrust.com)
- Integration with EIA/archivers: Many regulated firms rely on third‑party electronic archivers; SL2 offers automatic archiving into leading EIA providers, but compatibility and ingestion formats should be tested during pilots. (appsource.microsoft.com)
- Intune/UEM policies: The capture model (App Capture vs Carrier Capture vs Stacked Capture) affects device management choices and employee privacy—Intune policies, MDM app configuration and app protection settings must be planned and documented. (celltrust.com)
Strengths: why Microsoft AppSource and Teams integration matter
- Procurement friction reduced: Listing in AppSource and the Teams Store increases visibility to Microsoft customers and simplifies trial initiation—accelerating PoC and procurement cycles for Microsoft‑first organisations. (appsource.microsoft.com, techcommunity.microsoft.com)
- Familiar UX drives adoption: Exposing mobile messaging inside the Teams UI reduces training and context switching—users work in the same client they already use. Familiarity accelerates adoption and reduces helpdesk demand. (celltrust.com)
- Native governance leverage: Feeding captured messages into Microsoft Purview and E5 pipelines allows legal and compliance teams to apply existing retention, supervision and eDiscovery tooling to mobile data—reducing the need for separate workflows and lowering overall operational complexity. (celltrust.com)
- Flexible capture models: Supporting BYOD, COPE and COBO models—including Stacked Capture to combine app and carrier capture—gives organisations deployment flexibility matched to their privacy and control requirements. (celltrust.com)
- Advanced moderation and prevention: Newer SL2 moderator AI features aim to prevent risky messages from being sent—shifting compliance from reactive archiving to proactive blocking or quarantine where necessary. This is a significant evolution for firms that wish to reduce reputational or regulatory exposure. (helpnetsecurity.com)
Risks, limitations and points of caution
While the Microsoft marketplace availability is an important milestone, several practical and risk considerations must be weighed by IT, security and compliance teams:- Data residency and sovereignty: Marketplace listings note Azure Global as the default storage; organisations with strong data locality/regulatory demands must confirm Azure region options and the availability of Azure Government instances. Failure to validate residency can create regulatory exposure. (celltrust.com)
- Privacy on BYOD devices: BYOD capture models rely on app containerisation to separate personal and business communications. Despite vendor claims, privacy concerns and employee trust issues need clear policy communication and legal counsel review—especially in jurisdictions with strict employment privacy laws. (celltrust.com)
- Moderator AI false positives/negative risks: AI‑driven message moderation can introduce false positives (legitimate messages held or blocked) and false negatives (risky messages that bypass detection). Organisations should pilot moderation settings, establish escalation and review workflows, and keep forensic logs to defend moderation decisions. (helpnetsecurity.com)
- Archiver compatibility and fidelity: Automatic archiving to third‑party EIA systems requires testing around metadata fidelity, date/time accuracy and message threading. Misconfigured ingestion can complicate eDiscovery and legal holds. (appsource.microsoft.com)
- Vendor dependency for critical audit trails: Relying on a 3rd‑party capture vendor introduces supply‑chain and continuity considerations. Contracts should include audit rights, exit data‑export guarantees and SLAs for data access in case of service disruption. (celltrust.com)
- Regulatory nuance across jurisdictions: The regulatory regimes cited (SEC, FINRA, MiFID II, HIPAA, FOIA, etc.) differ substantially in permitted capture, consent and retention rules—organisations must validate the SL2 approach against specific local regulatory obligations rather than assuming a one‑size‑fits‑all compliance posture. (fintechfutures.com, celltrust.com)
Implementation checklist for IT and compliance teams
- Confirm licensing and procurement route with CellTrust and determine whether AppSource/Teams Store trial meets contractual needs. (appsource.microsoft.com)
- Validate data residency needs and request Azure Government or specific region deployment options if required. (celltrust.com)
- Pilot capture model(s) (BYOD/COPE/COBO) with representative user groups and legal/compliance stakeholders to validate privacy and functionality. (celltrust.com)
- Test archive ingestion into the organisation’s EIA, validating metadata fidelity, retention tags and discoverability in Microsoft Purview/Advanced eDiscovery. (appsource.microsoft.com, celltrust.com)
- Establish moderation settings, human review queues and audit trails for AI holds and blocks; run parallel monitoring to measure false positive/negative rates. (helpnetsecurity.com)
- Document incident response and exit procedures, including data export formats, access to historical captures and contractual SLAs. (celltrust.com)
Market context and competitive landscape
CellTrust operates in a niche but growing field: mobile capture + compliance inside enterprise collaboration ecosystems. Competitors include specialised archiving vendors, legacy telco capture solutions and newer platforms that offer APIs into Microsoft Purview or bespoke connector services. The strategic advantage of SL2 is its end‑to‑end capture model (app + carrier + stacked capture), Teams‑native experience and explicit marketplace presence—factors that favour Microsoft‑centric buyers.However, buyers should compare total cost of ownership and integration risk against alternatives that provide tighter coupling with existing archivers or that are delivered as part of a vendor’s larger compliance suite. For some organisations, building a custom ingestion pipeline into Purview from carrier capture or a managed service may be preferable if deep customisation or on‑prem storage is required. (celltrust.com, appsource.microsoft.com)
Final assessment and recommendations
CellTrust’s listing of SL2 in Microsoft AppSource and the Teams Store is a meaningful distribution milestone that simplifies discovery and trial for Microsoft‑first organisations. The offering strengthens the convergence of mobile communications capture with Microsoft Purview and Entra ID authentication, enabling compliance teams to apply familiar governance controls to mobile messaging channels. For regulated enterprises that already rely on Microsoft 365/E5 tooling, SL2 presents a practical option to broaden capture coverage without introducing a radically different UI or separate archiving silo. (appsource.microsoft.com, celltrust.com)That said, the benefits come with clear caveats: privacy and BYOD policies must be treated seriously; moderation AI requires careful tuning and governance; and data residency, archiver compatibility, and contractual exit terms must be validated before wide deployment. A recommended approach is a staged rollout: pilot SL2 with a limited, representative cohort; validate archiver ingestion and Purview searchability; tune moderation rules and human review queues; and expand only after legal, security and HR stakeholders sign off.
