Information Technology and Cyber Services

Tetra Tech is a leading provider of consulting, engineering, and technology services for government clients, with expertise in innovative application development, cybersecurity, data analytics, and cloud services in support of military operations worldwide.

Information technology continues to grow rapidly and exponentially, as both friendly and enemy states leverage the reach and power of cyberspace to achieve their interests and purposes. Defense organizations across the globe are committed to ensuring freedom of action and maneuver in cyberspace—while denying adversaries the same—by implementing advanced technologies designed to protect and secure the internet and all connected devices. Tetra Tech partners with defense organizations to protect and secure critical information infrastructure and modernize their enterprises for the expanding cyber battlespace.

Our IT and cyber expertise includes:

Aging information systems are a consistent problem across defense customers, with obsolete technology and an inability to meet the pace and demands of the modern cyber force. System consolidation and application rationalization are growing trends to streamline business processes and reduce ongoing costs for sustainment of multiple systems with similar and overlapping capability. Tetra Tech serves a diverse client base with mission-critical applications by leveraging open source and commercially available technologies. We support lifecycle management through a range of common and emerging methodologies that suit our clients’ needs and leverage integrated development environments for enterprise applications prior to deployment into the cloud or on-premise production environments.

Tetra Tech tailors our application development support to our clients’ capability and resources, choosing from a range of development methodologies and technologies, including:

  • DevOps
  • DevSecOps
  • Agile – Scrum/Kanban
  • Traditional – Waterfall
  • Hybrid Agile/Waterfall
  • Mobile Application Development
  • No Code/Low Code Platforms

Global cybersecurity requires a concerted and collaborative effort among nation states, industry, and academia to develop and implement common security policies, frameworks, and technologies. U.S., allied, and coalition defense partners are increasingly reliant on interconnected platforms, applications, systems, and networks to execute warfighting, security, peacekeeping, and humanitarian operations around the world. Tetra Tech helps our defense clients secure their systems and networks against real and emerging threats.

Tetra Tech has a deep understanding of applying U.S. federal information assurance (IA) and cybersecurity standards such as Defense Information Systems Agency (DISA) Security Technical Implementation Guides (STIGs), National Institute of Standards and Technology (NIST) Special Publication (SP) 800-53 recommended security controls for federal information systems and organizations, NIST SP 800-37 guide for applying the risk management framework to federal information systems, Trusted Facility Manual (TFM), Federal Information Security Management Act (FISMA), and Department of Defense Directive (DoDD) 8570 IA workforce improvement.
