Security gaps threatened the company’s cloud migration, but crisis was averted with services from Lightstream.

Business Challenge

A desire to stay innovative, modern, and operationally effective—three critical attributes in today’s competitive construction industry—led a large design-build construction company in the Midwest to explore the cloud. The company’s IT leadership team chose Microsoft Azure as their platform and purchased Prisma Cloud, a multi-cloud security offering from Palo Alto Networks, to provide added security protection for their cloud environments.

Once its Azure environment was implemented, the company began migrating applications. The team’s goal was to move as many applications as possible to the cloud, knowing some applications would have to remain on-premises, and their operating environment would result in a hybrid configuration.

After months of moving applications and deploying them into production, however, the company discovered problems. A security assessment revealed there were serious security gaps in the way Azure and Prisma Cloud had been implemented. If not addressed, the gaps would allow external entities to gain access to their environment, leaving the company’s systems vulnerable to breaches. This forced the company to stop its cloud migration and move applications back into its own data center.

Solution

With its cloud migration on hold, the company looked for a solution to solve its security problems and contacted Lightstream for help.

Once engaged, Lightstream Azure Cloud experts began gathering information. They reviewed the company’s business requirements, technology environment (infrastructure, data services, security landscape, application portfolio, and operations tools), and processes to gain a clear understanding of the company’s operating environment.

Next, the team evaluated the company’s existing Azure environment. They reviewed the company’s core cloud configurations, standards and governance, identity and access management (IAM), network interconnectivity, security, and monitoring, provided recommendations for changes to address issues, and then created an operational run-book with as-built documentation.

The next step was to review the Palo Alto Networks NGFW (next-generation firewall) configuration. The team reviewed the overall design of the appliances, assessed the Azure routing configurations, network placement, and connectivity, and recommended changes to remediate issues and ensure high availability.

The last step was to address the Palo Alto Networks Prisma Cloud implementation. The team evaluated the existing deployment, including policies and settings for resource configurations, user activities, network traffic, and host vulnerabilities, and made changes to resolve problems and ensure the environment operated correctly.

Business Outcomes

Remediation of Security Gaps and Reduced Business Risk

After completing the project with Lightstream, the company was able to eliminate its security gaps. External entities were no longer able to gain access to the company’s Azure environment through the known security vulnerabilities. This increased the confidence in the company’s cloud platform and lowered the risk of security breaches to the organization.

Secure Azure Environment with Next-Generation Firewalls

The company gained a secure Azure environment protected by Palo Alto Networks NGFWs in a high availability configuration. This enabled the company to resume migrating applications safely to the cloud and ensured its firewalls would be resilient.

Successful Prisma Cloud Implementation

With help from Lightstream experts, the company was able to overcome its initial problems and successfully implement Palo Alto Networks Prisma Cloud in its environment. This provided added security protection for the company’s cloud infrastructure and cloud-native applications.
