Subsentio is a trusted third party service bureau that helps telecommunications carriers and Internet providers meet their law enforcement assistance obligations.  We provide our clients with the technical solutions needed to comply with their lawful electronic surveillance requirements. On their behalf, we review and validate (in the US, Belgium, Canada, and Australia) court surveillance orders, implement the lawful surveillance, and provide similar support in response to other legal demands such as subpoenas and court orders for records held by the service provider.

CALEA Compliance

Some communication service providers (CSPs) wonder if they are subject to the Communications Assistance for Law Enforcement Act (CALEA). Others assume that their network hardware comes “CALEA compliant” from the factory and that no further action is required. Far too many believe that CALEA does not apply to them, at all.

In fact, CALEA applies to the vast majority of service providers. CSPs including ISPs need to be CALEA compliant. The service provider is required to install technical solutions for lawful electronic surveillance, and to operate those solutions in a privacy-protective manner. Hardware-resident CALEA software alone can’t do the job. The CSP also needs a mediation device or probe to establish the lawful intercept and deliver evidence in the proper standard formats for the relevant law enforcement agency.

That’s where Subsentio comes in. We can:

  • Analyze your network and provide a technically suitable, compliant solution.
  • Provide a CALEA-compliant technical solution for any kind of network: wireline, wireless, broadband access, VoIP, LTE, or VoLTE.
  • Provide the full array of “active” and “passive” technical solutions to ensure the perfect match for your needs.
  • Perform these services at a price that even small rural carriers and start-ups can afford.

Subsentio manages the whole process for you to make sure it’s performed correctly and to the letter of the law.  We review the court order for validity (in the US, Belgium, and Australia) interface with the law enforcement agency, set up the connectivity to the agency’s monitoring point, activate the surveillance solution on the targeted telephone number or IP address, trouble-shoot any technical disruptions, deactivate the solution when the court order expires, and perform the legally required record-keeping.

Records Production

Sometimes, instead of ordering you to intercept a suspect’s communications in real time, a court and/or law enforcement agency may serve you with a due process order such as a subpoena requiring you to disclose a suspect’s stored calling records or historical information.  Subsentio Records Production lets the CSP outsource this time- and resource-intensive process.  Fast, reliable and cost-effective, Subsentio Records Production runs on an automated, rules-based engine, is backed by 24 X 7 support for exigent needs, and indemnifies the client from legal action.


Finally, Subsentio gives our clients the training they need to perform the in-house portion of the law enforcement assistance process.  We ensure that your security staff knows the protocols used by law enforcement and the precautions expected by their privacy-conscious subscribers.  Whether you receive a court order for real-time surveillance or a request for stored records, your staff will learn to coordinate with our experts to give law enforcement just what the legal order requires.

The end result for Subsentio clients, whether the need is CALEA compliance or records production: peace of mind.
