Cybersecurity Transformation

Tetra Tech is transforming an enterprise-wide cybersecurity program so it can proactively mitigate risk
Tetra Tech is providing end-to-end cybersecurity support for a large federal client, including threat mitigation and incident response, security architecture, vulnerability management, risk management, and awareness training.
The legacy program for this client was compliance-oriented and consisted of completing required tasks and reporting as needed without considering proactive security and risk management. Our approach began with stabling a multi-functional program management office that clearly defined a governance structure and standards, and automated manual processes, policies, and procedures. We identified and remediated gaps in existing procedures and standardized incident response security measures for major cyber events and provided implementation support for forensics tools. In part, this approach included the provision of ongoing award-winning cybersecurity training, not only to address general awareness, but also emerging trends and how they can be implemented.
