What Is the Shield Connector for MobileGuard AT&T?

MobileGuard — now part of Smarsh — is an enterprise mobile communication archiving platform providing SMS and mobile message capture for regulated industries. MobileGuard AT&T refers specifically to the capture of SMS communications from AT&T-connected business mobile devices through MobileGuard’s NetGuard network-level solution. NetGuard is MobileGuard’s flagship carrier-level capture product — a network-based SMS archiving solution requiring no on-device application installation, capturing SMS directly from the AT&T network for regulated employees on AT&T corporate mobile plans.

AT&T is one of the two largest mobile network operators in the United States, providing business mobile services to millions of corporate customers — including a significant proportion of regulated financial institutions across the US financial services market. For broker-dealers, investment advisers, hedge funds, and trading firms with front-office staff on AT&T corporate mobile devices, MobileGuard AT&T NetGuard has provided a network-level SMS capture mechanism that meets the technical requirements of a carrier-based compliance capture solution.

The SMS records held within MobileGuard’s infrastructure from AT&T-connected devices are business records subject to the same SEC, FINRA, CFTC, and FCA recordkeeping and surveillance requirements as any other regulated electronic communication. Shield’s connector ingests these records into Shield’s compliance platform, applying AI-powered surveillance and making them available for cross-channel investigation.

As with the broader US mobile compliance enforcement landscape, the SEC and FINRA’s sustained focus on off-channel and mobile communications makes MobileGuard AT&T records a priority compliance data source — and the surveillance obligation remains unmet without integration into a dedicated compliance surveillance platform.

Why MobileGuard AT&T Compliance Is Complex

  • US regulatory enforcement focus on mobile SMS — The SEC and FINRA have issued successive enforcement actions specifically targeting unarchived and unsurveilled mobile SMS communications — imposing substantial penalties across major financial institutions. Firms that deployed MobileGuard AT&T to address their SMS capture obligation have addressed archiving; they have not necessarily addressed active surveillance. Shield applies the surveillance capability that enforcement actions make clear is expected.
  • The gap between archiving and surveillance — MobileGuard AT&T NetGuard captures and archives SMS from AT&T-connected devices without on-device apps. What it does not provide is AI-powered misconduct surveillance, cross-channel correlation, or eDiscovery workflows. SMS records in MobileGuard AT&T are archived; they are not actively surveilled without integration into Shield.
  • NetGuard network-level capture scope — NetGuard’s network-level capture on AT&T covers SMS from AT&T-connected corporate devices. Firms whose employees also use Verizon, T-Mobile, or personal devices need additional capture mechanisms for complete mobile SMS coverage. Understanding the scope of the AT&T NetGuard deployment is essential for identifying any coverage gaps.
  • Mobile-specific language and informality — AT&T SMS records require NLP models calibrated for financial services language to accurately identify misconduct signals.
  • Cross-channel continuity — AT&T SMS captured through MobileGuard must be correlated with Bloomberg IB, email, voice, and other channels to produce a complete business interaction record for investigations and examinations.
