The Challenge
Seeking auditable, separately billed remote desktops for auditor groups
Cherry Bekaert had a business need to provide secure, responsive, and auditable virtual desktops for accountants and third-party auditors. Lacking the internal resources to architect, build, deliver, and manage such a complex environment, it sought a managed service provider to deliver and manage a solution on its behalf.
The key requirements included secured shared storage to enable users to safely share documents with clients, secure access to its proprietary tools for audit purposes, and additional security controls to ensure a safe, auditable environment.
Additionally, Cherry Bekaert sought Cybersecurity Maturity Model Certification (CMMC) accreditation as a CMMC Third-Party Assessment Organization (C3PAO). CMMC is a unified cybersecurity standard for Department of Defense acquisitions aimed at securing the Defense Industrial Base (DIB) supply chain. This certification, which Cherry Bekaert acquired in 2022, enables the company to audit any defense industrial base and produce an assessment accepted by the Department of Defense.
Due to the compliance needs this certification requires, each group of auditors needed an application that required a file server and SQL server. There would also be multiple tenants (groups of auditors) in the AWS environment at the same time, which required separate organizations with delineated permissions and cost accounting for each.
Since CloudHesive is a Registered Practitioner Organization (RPO) authorized to provide guidance to organizations seeking CMMC compliance, the accounting firm turned to CloudHesive for support.
The Solution
Implementing a secure, CMMC-compliant, fully managed virtual desktop environment that scales up and down with seasonal need
CloudHesive worked with Cherry Bekaert to understand its complete set of requirements and needs. The CloudHesive team worked hand-in-hand with its internal team to build and present a secure, scalable cloud architecture to present to the security team for review and approval.
The CloudHesive team built and deployed a CMMC-compliant, scalable virtual desktop solution on the AWS cloud. For the solution’s foundation, the CloudHesive team used Amazon Virtual Private Cloud, Amazon Elastic Container Store (EC2) for cloud storage, and Amazon Elastic Block Store (Amazon EBS) as a storage area network (SAN). To enable virtual desktops for audit teams, CloudHesive deployed Amazon WorkSpaces virtual desktop infrastructure and Amazon WorkDocs for document sharing.
To meet Cherry Bekaert’s security and multiple tenant requirements, the solution included deploying a well-architected, multi-account AWS environment called a Landing Zone. To that, to meet security requirements, CloudHesive implemented a security control plane, integrating multiple third-party cybersecurity tools, including Trend Micro for end point security, DUO to establish multi-factor authentication, and Datadog for SEIM.
To provide multi-tenant billing transparency, CloudHesive used tagging and AWS Cost Explorer, which enables users to visualize, understand, and manage AWS service costs. These tools provide the means to separate AWS bills according to tenants and charge back to the appropriate auditor groups, keeping billing accurate.
CloudHesive also deployed Centricity, a platform built on top of Amazon WorkSpaces, to provide additional visibility into and easier management of Amazon WorkSpaces.
The final solution was a fully managed, highly secured and controlled environment that enables Cherry Bekaert to grow its accounting and audit business line while leaving IT maintenance and management to CloudHesive.
The benefits
Expanding customer base using a scalable, compliant virtual desktop solution
The solution enabled CMMC-compliant, auditable, and scalable virtual desktops for accountants and third-party auditors at Cherry Bekaert, enabling the firm to expand its clientele to those Department of Defense contractors requiring CMMC-compliant audits.
“CloudHesive was fantastic to work with,” said Jack Redfield, Information Security Officer at Cherry Bekaert. “They architected an extremely secure Amazon Workspaces solution that allowed us to securely leverage our proprietary technology and increase our professional services capacity overnight. In addition, the managed service CloudHesive provides on secure AWS workspaces now permits Cherry Bekaert to expand our client base to those demanding this type of controlled environment for their data.”
Additionally, the solution enables the firm to save on costs by scaling up during tax season and scaling down the rest of the year.
