Certifications

As a trusted partner of choice to governments, industries and communities around the world, data and information security is at the forefront of everything we do. We continually pursue the highest level of certifications, accreditations, global quality standards and compliance obligations across our business segment.

ISO/IEC 27001

ISO/IEC 27001 is the world’s best-known standard for managing information security systems. It defines requirements that an Information Security Management Systems (ISMS) must meet to obtain certification. The ISO/IEC 27001 standard provides companies of any size and from all sectors of activity with guidance for establishing, implementing, maintaining and continually improving an ISMS. Conformity with ISO/IEC 27001 means that an organization or business has put in place a system to manage risks related to the security of data owned or handled by the company, and that this system respects all the best practices and principles enshrined in this International Standard.

We successfully completed an audit by third-party firm BSI Group Canada Inc. to verify that it meets all requirements of the ISO/IEC 27001 standard.

Great Place to Work™

ERS’s Great Place to Work™ Certification is a measurement of an organisation’s Trust Index score. A confidential Trust Index survey is carried out within organisations, broken down into three overarching themes: Achieving Objectives, Personal Best and Team.
