Industry-specific solutions

Financial Services and Trading

Banks, Investment funds, credit-card companies, insurance companies and accountancy firms need to comply with regulations such as FINRA, MiFID II or EMIR.

These regulations require blocking communications where there can be conflict of interests, for example, when investors talk with researchers that possess non-public information



HealthCare institutions that need to comply with regulations such as HIPAA, need to control communications that could contain sensitive patient information.

For example, restricting doctors from sending files to prevent information mishandling



Educational institutions often need to restrict communications to avoid behavior breaches and other unpleasant consequences. SphereShield can be used to create policies such as restricting a 12th grader from communicating with a 5th grader.

Common Problems Solved by the Ethical Wall

Block File Sharing Between Groups or External Domains

SphereShield Ethical Wall blocks file sharing across groups or external domains not allowing any loopholes in the process


Protect Users Privacy

Companies that want to restrict communication between C-Level Executives and the rest of the company can prevent them from receiving unsolicited communications

The Ethical Wall can allow those executives to send messages and files but not the other way around

Third Party

Third-Party or Outsourced Companies Restriction

SphereShield Ethical Wall can create policies to allow only one department to communicate to an external company, while blocking all other departments from doing so. Another scenario is when a company doesn’t want to allow meetings between external and internal employees.

Ensure that appropriate notifications are communicated to external and internal contacts.
