External Auditing Services: IT, Accounting & Data

At Linford & Company, our auditors are experts in SOC 1, SOC 2, HIPAA compliance, and FedRAMP® assessments. Our backgrounds are diverse, spanning from decades of combined auditing experience in the “Big Four” firms to decades of combined experience in security engineering of highly complex and sensitive systems for the federal government. With each engagement, our team follows our proven approach and leverages their vast experience to work efficiently, develop superior products, and minimize the impact to our clients, all at a fair fee. We welcome you to inquire about our auditing and assurance services.

System and Organization Controls (SOC) 1 audits are intended for service organizations providing services related to their clients’ internal controls over financial reporting (ICFR).

SOC 2 audits are for service organizations that do not necessarily provide services relevant to their clients’ internal controls over financial reporting. A SOC 2 audit is an independent audit of a service organization’s compliance with one or more of the SOC 2 Trust Services Principles and Criteria which are Security, Availability, Confidentiality, Processing Integrity, and Privacy.

A HIPAA compliance engagement entails the evaluation of the internal controls in place at an organization to meet the requirements of up to three HIPAA rules—security, privacy and breach notification—related to their electronic protected health information (ePHI) environment. HIPAA compliance audit reports provide the independent auditor’s opinion as to compliance with the in-scope requirements of the regulation itself; whereas, HIPAA compliance assessment reports focus only on reporting gaps in compliance.

HITRUST Common Security Framework (CSF) assessments and certification are for healthcare providers and their service organizations who transmit and store Protected Health Information (PHI). HITRUST CSF certification demonstrates an organization’s compliance with regulations and security standards designed to safeguard PHI. A Certified HITRUST Assessor performs customized HITRUST assessment based upon an organization’s unique environment to independently validate the entity’s self-assessment in order for HITRUST to certify the organization.

Cloud Service Providers (CSP) offering cloud services to federal agencies must meet Federal Risk and Authorization Management Program (FedRAMP) requirements. As part of the FedRAMP program, independent assessors, called Third Party Assessment Organizations (3PAO), assess CSP cloud offerings for FedRAMP compliance and assist the CSPs through the FedRAMP process toward achieving an Agency Authorization to Operate (ATO) or a Provisional ATO (P-ATO) through the Joint Authorization Board (JAB).

Cloud Service Providers (CSPs) delivering services to state and local agencies are required to adhere to the Government Risk and Authorization Management Program (GovRAMP) standards. Within the GovRAMP framework, Third Party Assessment Organizations (3PAOs), acting as independent assessors, evaluate CSP cloud offerings for compliance with GovRAMP requirements and guide CSPs through the GovRAMP process in order to obtain an Authorization to Operate (ATO).

NIST 800-171 and CMMC assessments are for organizations which interact with sensitive data, in support of programs which interact either directly or indirectly with the federal government and Department of Defense. The type of assessment required will depend largely on the way the organization interacts with information of various classifications and what entity will be the recipient of the assessment report. For entities doing business with the DoD, the CMMC certification process will provide organizations the opportunity to demonstrate compliance with requirements based largely on NIST standards such as 800-171.

Cutting edge penetration testing and attack simulation, powered by real world threat intelligence gathered through postmortem examinations of successful attacks, using the MITRE ATT&CK framework. Our penetration tests include comprehensive evaluations of Physical Assets, Network Infrastructure, Cloud Resources, Web Applications, Mobile Apps, and Source Code Security Reviews. By Identifying vulnerabilities and weaknesses, we help organizations proactively strengthen their defenses against cyber threats.

Achieving ISO/IEC 27001:2022 certification acts as a business differentiator, having this certification is affirming to an organization’s suppliers, clients, and stakeholders that their business takes information security management seriously. Certification showcases an organization’s dedication to continuous improvement, development, and safeguarding of information assets and sensitive data through the implementation of proper risk assessments, policies, and controls. ISO/IEC 27001:2022 compliance certification is achieved upon the successful completion of an assessment.

Achieving ISO 27701 certification differentiates your organization by demonstrating to controllers, processors, customers, and regulators that personal data is handled under a formal Privacy Information Management System. The 2025 revision is now a standalone PIMS standard — it no longer requires an underlying ISO 27001 certificate. Linford & Company helps organizations achieve readiness for this standard today, and will offer accredited certification audits against the standard when those services become available.

Merchants that accept payment cards as payment for goods and/or services and service providers involved in the processing, storage, or transmission of cardholder data on behalf of another entity or providing a service that controls or could impact the security of cardholder data are required to be PCI compliant. Our Qualified Security Assessors (QSAs) can assist you with both self-assessment questionnaires (SAQ) and report of compliance (ROC).

The CSA STAR (Security, Trust, and Assurance Registry) is a certification program designed by the Cloud Security Alliance to provide transparency and assurance regarding the security practices of cloud service providers. It evaluates cloud providers against industry standards like the Cloud Control Matrix (CCM) and offers two areas of assurance: Level 1, self-assessment and Level 2 third-party assessment. By completing the Level 1 and attaining Level 2 Attestation for SOC 2 or Level 2 Certification for ISO/IEC 27001, CSA STAR helps organizations assess and select trusted cloud providers that have achieved the above stated levels while promoting accountability in cloud security.
