network design and engineering

Every client has unique enterprise network design and engineering needs. DIS’s Solution Architects have complementary skills and experience with industry-leading Enterprise Architecture (EA) processes to assist with end-to-end modeling, application, infrastructure modeling, and security modeling. Our engineers have implemented each of these to help various federal agencies work toward the same goal of synchronizing technology performance within their various business processes. 

In the digital age, your network is not just a utility; it's the central nervous system of your entire business. We design and architect secure, high-performance, and reliable enterprise networks that eliminate bottlenecks and provide the resilient foundation your business needs to thrive. Many businesses are struggling with legacy networks that were never designed for the demands of today's cloud-centric, mobile-first world. A modern enterprise network is more than just a collection of switches, routers, and firewalls. It's an intelligent, automated, and secure platform that must be architected to support every aspect of your business operations. Solution Architects work with clients to design custom enterprise network solutions that align with their business needs and objectives, leveraging industry-leading EA processes.  We treat network design as a strategic discipline. We start with your business objectives—not with a specific piece of hardware—to create a holistic blueprint for a network that delivers the speed, reliability, and security your business demands, both today and tomorrow. 

Your network is the lifeblood of your organization, but its complexity is growing exponentially. In a complex, dynamic network, hope is not a strategy. Our Network Infrastructure Modeling services create a sophisticated "digital twin" of your entire network, allowing you to simulate changes, predict behavior, and validate resilience before you ever touch a production device. We move your organization from reactive troubleshooting and hopeful deployments to proactive, data-driven certainty. Network Modeling is the practice of creating a mathematically accurate, software-based replica of your entire network infrastructure. 

This "digital twin" ingests the live configuration and state of every router, switch, firewall, and load balancer—both on-premise and in the cloud. It understands every protocol, access list, and routing policy. This gives you a perfect sandbox to safely test any change, simulate any failure, and understand the precise end-to-end behavior of your network without any risk to your production environment. We leverage cutting-edge network infrastructure modeling tools to design and implement network infrastructure solutions that are optimized for performance, scalability, and security. 

Your security policies are complex. Can you be certain they're working? Your organization has invested heavily in best-in-class firewalls, cloud security, and a robust set of security policies. Traditional security audits are manual, point-in-time, and error-prone. Vulnerability scans are essential, but they can't see the complex routing and policy interactions that create unintended access paths. 

We replace assumptions with proof. Network Security Modeling is the practice of creating a complete, end-to-end software replica of your network's security fabric. Understanding every access control list, firewall rule, cloud security group, routing policy, and network address translation across your entire hybrid environment allows us to move beyond spot-checks and perform a comprehensive, automated analysis of your security posture. 

We can ask millions of "what-if" questions to test every possible traffic path against your intended security policy, providing you with a level of assurance that manual audits can never achieve. We help clients enhance their network security posture through advanced network security modeling, ensuring that networks are protected against both internal and external threats. 

Our engineers have extensive experience in modeling network applications, ensuring that clients have a high-performance, reliable network infrastructure to support their business applications. 

DIS's engineers help clients optimize network performance through network analysis and monitoring, identifying and addressing performance bottlenecks to ensure that networks run smoothly and efficiently. 

Ensure your network is an enabler, not a limitation. Our network capacity planning services use data-driven analysis and strategic forecasting to create a precise roadmap for your network's future; Network Capacity Planning is a strategic discipline that moves you from guesswork to foresight. It is the formal process of analyzing your current network performance and aligning it with your future business goals to ensure you have exactly the right amount of capacity at precisely the right time. Effective capacity planning requires a holistic view. We analyze every potential bottleneck in your network to provide a complete picture. Our engineers work to plan and design network capacity solutions that can accommodate future growth and changing business needs, ensuring that networks are scalable and flexible. 

Waiting for your network to fail before giving it attention is a reactive strategy that leads to predictable problems.  A reactive approach is always more expensive, more disruptive, and more stressful than proactive care.  From reactive firefighting to proactive stability and peace of mind, we provide ongoing network maintenance and support services to ensure that clients' network infrastructure is up-to-date, secure, and functioning optimally. 

We provide solutions to automate security processes, such as vulnerability scanning, patch  DIS's engineers have extensive experience in integrating diverse network systems and technologies, ensuring seamless communication between different network components and maximizing network performance. 

Our elite team of senior network engineers specializes in rapid root cause analysis for the most complex, intermittent, and performance-degrading network problems, restoring stability, speed, and peace of mind. Your business is being impacted. 

The application team says it's the network. Your network team says it's the application. Meanwhile, the problem persists, users are frustrated, and the blame game consumes valuable time. We are the fresh pair of expert eyes your problem needs. We are not just another IT vendor; we are a dedicated team of high-level troubleshooters who thrive on solving the unsolvable.

We bring a systematic, data-driven methodology and a suite of advanced diagnostic tools to your environment. We don't guess. We start by gathering evidence, analyzing the data, isolating the problem domain, and methodically drilling down until we find the definitive root cause. Our engagement provides a clear, unbiased, and evidence-backed path to resolution. DIS's resources are skilled at quickly identifying and resolving network issues, minimizing downtime and ensuring that clients' networks are operating at peak performance. 

DIS provides comprehensive network documentation services, ensuring that clients have detailed information about their network infrastructure, including network topology, hardware and software configurations, and security protocols.
